Mechanical spring starter can start diesel engines in any special environment releasing the spring’s potential energy. The spring stater motor requires no battery or any other external system, only by hand. It is the ideal backup starter, especially suitable for firefighting, emergency rescue, military, marine and other environments that require high starting reliability. It is also the best starting solution of “black start” or “dead-ship start".
I guess everyone will work with an engine in daily life, and the most common engines are car engines and motorcycle engines. As we all know, the engine is the source of power that can bring power to modern society.
While every engine must be started by the starter, the common starter is an electric starter that needs a battery to provide energy. Other starting methods like air starter, require an external system to provide energy. All of them rely on external power; once they lack external power, the engine is “dead”.
Although the electric motor is convenient and even automatic, it still needs maintenance. If the starter is out of maintaining or out of electricity, the engine won't start. It is fine for common situations, but it will cause bad results if it is an emergency.
But how can we avoid this? It is easy to understand the principle and solve the problem. Let’s focus on the engine of a motorcycle, every motorcycle will be equipped with a kicking starter for start engine. It is an easy and simple way to start an engine if the electronic starter doesn’t work.
We can also provide an alternate startup option for other engines, mechanical spring starter. It is based on different principles comparing with the kicking starter of a motorcycle. It can start a diesel engine in any special environment by releasing the spring’s potential energy. Cqstart 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. The mechanical spring starter can apply to emergency generator sets, lifeboats, firefighting sets, emergency pump sets, construction machines, power plants, irrigation and drainage device, etc.
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 basic composition of Cqstart spring starter
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 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.
Fire Pump
In the event of a power failure in a fire accident, the fire-fighting unit needs to be able to start normally and drive the water pump to extinguish the fire. The requirements for the reliability of the diesel engines are very high. If for some reason, the diesel engine cannot start successfully, the mechanical starter is required as a backup solution to ensure the engine starting.
Emergency
Most of the emergency rescue is mobile, generally in the state of warehouse storage, relatively lack of battery maintenance. Usually meet the failure to start an engine. It is difficult to find backup battery power under the emergency situation. At this time, the mechanical starter can be used to manually start the engine for the rescue problem.
Marine
When the marine ships meet the situation of power off, the emergency generating set is used to generate power for the ship. Mechanical starter is an ideal choice as the backup device for the emergency engine start.
Military
Under the conditions of field military training, the environment is hard and harsh, and the backup is always insufficient. When the battery is out of power, the important military equipment can’t work normally, which may cause serious consequences. The mechanical start device will solve the problem and can ensure the engine starting by manual system without any other external energy.
Special Environments
There’s always no electricity or the power is low under the environments includes mining, offshore gas and some special chemical plants. The engine starter with mechanical starting system will effectively work under these special environments.
Backup Of Other Engine Starters
The mechanical start system can be used as the back up and replacement of other engine starting system, applicable installing on the diesel generator sets of land and marine, mining machinery, engineering machinery and agricultural irrigation and drainage machinery.
