How can start the engine when it is lack of electricity?
The most popular starter is an electric starter which is convenient and even atomized. But it cannot start an engine once it lacks maintenance or electricity. A mechanical spring starter can solve this issue. It is the perfect solution to start the engine when the electric starter cannot work without electricity. Starting diesel engine at max 50 liters displacement, which only needs manpower.
It can store the manpower energy by compressing the disc springs. After that, the operator can release the energy by pulling the trip lever.
Application Scenes and Details
Firefighting
As diesel engines will drive a water pump for extinguishing, it requires high reliability of diesel engines during firefighting. Once the electric starter breaks down, a mechanical spring starter will be the more reliable backup starter.
Emergency Rescue
Most of emergency rescue sets are movable, usually mothballed in a warehouse. It causes that the sets lack of maintenance for battery. And it is hard to find a backup battery immediately when there is an emergency. However, Cqstart mechanical spring starter is maintenance-free, it hardly malfunctions if the operation is correct.
Marine
The mechanical spring starter can meet the “black start” requirements of the power unit of the ship, if there is an event of electricity loss during the ocean sailing. In the ship regulations, it is required by the SOLAS when the ship is sailing. All ships need to be satisfied that when the whole ship loses power, there should be an emergency unit used to generate electricity for the ship. The mechanical spring starter is designed to achieve the emergency start requirements.
Military Usage
The environment of the wild field is very harsh, and backup resources are insufficient. Generators, vehicles and other vital equipment cannot work, once encountered a shortage of electric starter power. Under this circumstance, you can lean on a mechanical spring starter to start the generators to provide electricity.
Of course, a mechanical spring starter can be used in more than these scenes. All I want to discuss is that the Cqstart mechanical spring starter can apply to varies scenes and different situations, even extremely harsh conditions.
The shipping industry experienced a glorious period from 2000 to 2009 in China, but from 2010, due to the global economic recession, the shipping industry faced the most serious crisis. The situation forced the companies in the field to make the transformation and upgrading. Now the shipping industry is in the phase of transformation. But the all kinds of marine equipment is in demand at any time. YSmarines, based in China, exports the marine equipment to the whole world.
Marine equipment is a general name for many equipments in a vessel. Here we only introduce the simple equipment mainly for accommodation, including marine ladder, marine window, marine door and marine hatch cover. They are necessary parts in one vessel.
Marine ladder is used as the tool to go aboard or ashore, or up and down different deck. The most main products are accommodation ladder, aluminum wharf ladder, pilot ladder, embarkation rope ladder. The accommodation ladder can be manufactured by aluminum or steel. It is usually installed and collected on the shipside, when along with the gunwale released outboard tilted for marine personnel up and down the vessel. It includes ladder frame, upper platform, lower platform, turning device, post, electric or pneumatic winch, safety net and other accessories. The Lowering and hoisting of the ladder is controlled by the winch. Aluminum Wharf ladder also can be called as gangway. It is used as the ladder between the vessel and the dock. It is light, and the handrail is removable. Pilot ladder and embarkation ladder are both rope ladders. They are made of aluminum or hardwood steps and rope. The only difference is that the pilot ladder with anti-twist boards.
Marine window makes the light or the air into the cabins. It is mainly made by aluminum or steel, can be bolted or welded on the bulkhead. The window shape can be changed according to the installment position. According to the function of the window, the designer can decide the window is fixed or open. And the window also can be with electric heating or fireproof. The most widely used window is rectangular window & side scuttle. The rectangular window is used for wheel house, meeting room and deck houses, other superstructures above the freeboard deck. It is fixed or openable. The opening direction is varied. Side scuttle is also called as porthole, normally it includes three parts, the dealight (storm cover), the window frame, the window seat. It has many types according to the different material, opening direction & installment type. we have the detailed introduction for the window opening direction, material, types in our website.

The research on the material of cold-rolled work rolls has always been highly valued by the roll industry. From the initial bearing steel, it has gradually developed to 2% Cr, 3% Cr, and 5% Cr section steel. Its development is usually based on the continuous improvement of chromium content. In recent years, semi high-speed steel and high-speed steel roll materials have been developed and there have been some reports on their microstructure and carbide research. The technicians have studied the quenching process of a newly developed forged high-speed cold-rolled work roll material and analyzed the quenching temperature on the structure, grain size, residual austenite and hardness of the high-speed steel rolls, which provides the theoretical and experimental basis for the development of high-end cold-rolled work rolls.
The new type forged high-speed steel roll material used in the test was smelted in a 50kg vacuum induction furnace and then forged at a high temperature to produce a 100mm × 100mm × 250mm billet, which was annealed at 700°C for 4h to obtain the test raw material. The metallographic sample is a 15mm × 15mm × 15mm block, which is heated at different temperatures by a box-type resistance furnace and quenched by air cooling. The hardness was measured using a 660RLD / T Rockwell hardness tester and the residual austenite was detected using an X’perPro X-ray diffractometer, the structure and grain size were measured using an Axiovert200MAT optical microscope, and the carbides were observed using a QUANTA400 scanning electron microscope.
The microstructure of the new forged high-speed steel rolls is lower bainite + bainite + a small amount of martensite + bar carbide + granular carbide. Among them, large bar carbide is precipitated during the solidification of molten steel. Primary carbides, granular carbides are secondary carbides precipitated from austenite during cooling, and the carbide content is 3.6%.
The quenching temperature of the forged high-speed steel roll
(1) The quenching temperature affects the dissolution of carbides. As the quenching temperature increases, the carbide content in the quenched structure of high-speed steel rolls gradually decreases. When the temperature increased to 1200 °C, the granular carbides had been basically dissolved, leaving only a small amount of massive carbides.
(2) With the increase of quenching temperature, the grains of high-speed steel continues to grow. When the quenching temperature exceeds 1040 °C, the grain growth tendency is obvious. The quenching temperature exceeds 1160 °C and the grain size reaches 4.5, then the grain coarsening will become very serious.
(3) As the quenching temperature increases, the residual austenite content increases continuously. When the quenching temperature is below 1080 °C, the residual austenite content increases relatively slowly and then its content increases sharply. When the quenching temperature reaches 1160 °C, the residual austenite content increases to 38%. So the quenching temperature should be lower than 1080°C, considering the control of residual austenite content.
(4) When the quenching temperature reaches to 1040 °C, the hardness reaches its peak value of 64.1HRC. At this time, the matching of the structure, grain size and residual austenite content could be the best for the high-speed steel roll.
(5) The quenching temperature of the new-type forged high-speed steel roll materials should be selected between 1020 ～ 1080 °C.

Cqstart spring starter, the mechanical spring starter assembly consists of four major parts: a disk drive mechanism, an energy storage mechanism, a release mechanism and a clutch mechanism. The figure below shows the basic structure of a typical disc spring energy storage motor.
The Main Work Process Of Cqstart Spring Starter
The energy storage mechanism is the main mechanism of Cqstart spring starter, the main parts are disc springs and main shafts. Together with the components, they cooperate with, the following functions are realized. First, they can convert the aforementioned manpower input torque into an axial force. This force is compressed and turns into energy which is stored in the disc spring group. Secondly, they can convert the spring potential energy which is stored through compressing spring into torque output through the main shaft to form the power that drives the rotation of the diesel engine.
Detailed Operating Structure Of Cqstart Spring Starter
The Releasing Mechanism
The release mechanism is a part of the operating mechanism for spring starter, its main parts are the lifting rod assembly and the releasing lever working chain. The operator performs two operations with the lifting lever and the releasing lever. The purpose of operating the lifter is to keep the releasing mechanism in a state of being ready for energy storage, in which state the rotation of the spindle will be limited in order to achieve energy storage of the spring. The purpose of operating the releasing lever is to cancel the limitation of the spindle rotation when the diesel engine needs to be started; and at the same time completing the discharge of the disc spring, the output torque of the spindle, and the starting process of the diesel engine. In that progress, the shaft drives the flywheel drive gear to rotate.
The Clutch Mechanism
The clutch mechanism is a mechanism that combines and disengages the movement of the spring starter and the engine. The main part is the flywheel drive gear, which generates axial movement by means of a spiral groove on the starter main shaft. When the diesel engine needs to be started, the main shaft rotating pushes it to move in the direction of the flywheel to achieve meshing with the flywheel ring gear. Conversely, when the starter is working and the diesel engine begins to rotate actively, the flywheel of the diesel engine drives the rotation of the flywheel for driving gear while moving it backward along the axis, disengaging engagement of the gears.
disc drive mechanism The disc drive mechanism is a manpower input mechanism, and the main parts are the disc drive shaft and the transmission gear. It is the only way to convert manpower into spring energy. One of its functions is to determine the disk movement space and the angle required for the disk to make the operation convenient and comfortable. Secondly, it changes the direction of the input torque so that the axis of rotation conforms to the axis direction of the disk spring energy storage. Third, it can limit the reversal of the disc axis. And last, it is the radial support of the spindle and the axial thrust.
Easy Way to Start a Diesel Engine
Cqstart spring starter is easy to operate when there is short of electricity, which compares with other ways. When the diesel engine needs to be started, first needs to ensure that the diesel fuel supply system of the diesel engine works normally. Then pulling the lifting rod of the starter to make the releasing mechanism in the preparation state of energy storage, and using the rotating handle to rotate the starter disk in the specified direction for reaching the required energy storage state. And then, pushing the releasing lever in the direction indicated. After that, the diesel engine will be started.
The development trend of international trade has been greatly enhanced the forward progress of shipping industry. However, the area of ocean is much bigger than that of land. With the largely developing of shipping industry, all kinds of marine and offshore products for various ships and vessel such as stockless anchor and JIS marine valve also have great market space. The marine valve especially the marine globe valve is the most important part on vessel board. There are some advantages and disadvantages about this commonly equipment in ship.
The marine globe valve has much more advantages, which are very useful for each employee on the ship board. If people want to purchase this useful valve for vessel, they could browse the website ysmarines.com , the best supplier for all kinds of offshore products.
First, the globe valve has the simple structure which has already made the manufacturing and maintenance of this valve become more and convenient. The trip of most of ship should be much longer and it would be few opportunities for them to have repairing and supplying on land. This kind of situation has determined that all of equipment and devices on vessel should be easy to be repaired. The stop valve could meet this need.
Second, the working stroke of the marine globe valve is smaller than most of other valve. Because of this advantage, the opening and closing for this machine is very short. This kind of strong point could largely reduce the failure rate of this machine.
Thirdly, the globe valve has good sealing and the friction force between the sealing surfaces Marine Anchor is very small. These two points could largely help people prolong the service-life of this machine. On the other hand, it could also let the operation of this kind of valve become very stable.
Apart from the advantages of this kind of valve, there must be also some defects for this machine. These shortcomings could be concluded into factors below.
First, the fluid resistance of the globe valve is very large so the force required to open and close this valve should be large. This point is because of the simple structure of this valve. However, the ship server must be stronger enough or they would not open and close the valve.
Second, this kind of valve could not be applied with media liquid which have particles, viscosity and easy coking. Otherwise, the situation of failure would be very frequently.
Thirdly, the adjusting ability and performance of this kind of globe valve is very poor. That is depends on the simple structure.
However, types of marine globe valve could be divided into the flanged type, the external JIS marine valve thread type and internal thread type. According to the flow direction of media fluid, there are straight type valve and angle type. Please visit ysmarines.com to get more information about this product.
The mechanical starter is the ideal solution for engine start without external solution. Engine is the source of power, bringing power to modern society.While engine must be started by starter. The common starter is electric starter which needs battery to provide energy. Other starting methods like air starter, require external system to provide energy. All of them rely on external power. Once lacks external power, the engine is “dead”. With mechanical starter, the problem will be solved. Dalin spring starter, using a simple mechanical mechanism, stores the energy by compressing the springs and releases the spring’s potential energy by pulling the trip lever to turn the engine’s flywheel.
What is mechanical spring starter?
A mechanical starter which stores the manpower energy by compressing the disc springs and releases the energy by pulling the trip lever. And then the drive pinion will drive the flywheel to rotate.
It is the ideal solution for black start, mostly used in military, emergency rescue, firefighting, marine and some other conditions where require high reliability. It is also called mechanical spring starter, spring startup, hand starter, hand operated spring starter.
Advantages of mechanical spring starter.
Compared to electric starter, mechanical spring starter is maintenance-free. And compared to other means of starting, spring starter requires no external system such us battery, cable, air compressor, fuel tank and so on. Spring starter is waterproof, anti-corrosion, and produces no sparks. With natural anti-explosion structure, you can use it anywhere dangerous.
How to fit a mechanical starter to the engine?
(1)Most of flywheel housings have two bores. Electric starter has taken a bore. And spring starter can be installed to the other bore.
(2) If the engine only has one mounting bore, just remove the electric starter and install Dalin spring starter to the mounting bore when needed.
