Cqstart Spring Starter - Mechanical Emergency Engine Starter

Spring starter is a cost-effective mechanical starting device, which provides engine emergency starting solution when the battery lacks power. The mechanical starter is a complete system, not any other auxiliary required, widely used in the fire pump, military, marine, emergency rescue, petrochemicals, etc.

Working principle of spring starter
Spring starter uses disc springs to store and release energy, suits mini, medium, heavy-duty, and super heavy-duty diesel engines.

Spring starter composition
One spring starter assy is comprised of four mechanical systems including hand cranking, energy storage, energy release and clutch system.

Hand cranking system
The hand cranking system consists of the crankshaft, drive gear, etc. It is designed to input and conveys manpower. There are four functions of this system. First, it determines the space and angle for hand cranking. That makes operating more convenient and comfortable. Second, the rotation direction of input torque is adjustable, ensuring rotation direction accord with axis direction of spring starter’ main shaft. Third, the hand-cranking system limits the reverse rotation of the input adaptor. Fourth, it supports the main shaft in axis direction and thrust the main shaft in the radial direction.

Energy storage system
The energy storage system is the main mechanism of the spring starter. It consists of disc springs, main shaft, and some other auxiliary parts. There are two functions. One is converting input torque from the hand-cranking system to the force in the axial direction. The disc springs will be compressed by this force to store energy. The other one is converting the potential energy of disc springs to the output torque of the main shaft.

Engine release system
The release system is manipulating the mechanism of the spring starter. Its main spare parts are reset k**b assy and trip lever. Reset k**b controls energy storage status. Manipulate reset k**b to stop the main shaft from rotating, so that the whole system is ready for energy storage. When energy is full, manipulate the trip lever to release the main shaft. While disc springs will be decompressed, and the main shaft starts to rotate, driving the drive pinion to rotate, in order to drive the engine flywheel.

Clutch system
Clutch system controls spring starter engage and disengage with engine flywheel. The major part of the clutch system is the drive pinion. It is able to move in an axial direction with the aid of a spiral flute on the main shaft. Before starting the engine, the rotation of the main shaft drives the pinion to move forward to engage with the engine flywheel. When the engine starts to work, the engine flywheel’s rotation will drive the pinion to disengage with it.

How to operate spring starter
It is easy to operate the spring starter. First, you need to confirm the fuel supply is prepared. Then pull the reset k**b, the trip lever will be at the “RESET” position. Use the winding handle to crank the input adaptor for specified turns to energy full. Pull the trip lever in the indicated direction to start the engine.

How to choose the right spring starter
Customers can select the product according to the engine’s displacement, load, installation space and so on. And a customized spring starter can be designed and manufactured depending on the installation interface of the engine.

High Performance Spring Starter From Cqstart

Spring starter will provide mechanical starting when the battery of electric starter lacks power, which makes emergency/auxiliary generator sets more reliable to meet the requirements of firefighting, emergency rescue, military, marine, or some other harsh environments. The units of energy input, storage, transfer, and release are integrated into one spring starter assy. Requiring no external systems, the spring starter is a little larger than an electric starter. It only needs manpower to wind the input adaptor by winding handle, and the springs inside will be compressed to store energy. By pulling the trip lever, energy will be released to turn the engine flywheel. Then the engine gets started.

Advantages Of Spring starter
Self-contained unit(Unlike air/pneumatic or hydraulic starter, spring starter requires no external systems as air compressor, air tank, tube, etc. )

Cost-effective (the price of a spring starter is much lower than that of air/pneumatic or hydraulic starter system)

Maintenance-free (advanced solid grease, no need for maintenance)

Mechanism (Spring starter only needs manpower to wind the input adaptor by winding handle, and the springs inside will be compressed to store energy. By pulling the trip lever, energy will be released to turn the engine flywheel. There is no pollution when operating.)

Anti-explosion (pre-engaged pinion, natural anti-explosion structure, suits any spark sensitive application )

Hand-barring (Spring starter has turning gear for hand barring which makes daily maintenance more convenient)

Waterproof, oil-proof, salty mist proof (Spring starter is corrosion resistance with a baking varnish finish and mechanical components)

High/low-temperature resistance (The environment’s temperature has little influence on a mechanical device.)

Easy to install (Standard SAE mounting face, using several bolts to install spring starter on the engine.)

Uncomplicated operation procedures (One operation circle will cost 30 seconds, 10 seconds for a small engine.)

No liquid grease, no magnetism (Spring starter meets the safety requirements of air transportation, having no influence on other devices.)

How to configure the spring starter?
1. Most engines have two bores (multi-bores) in the flywheel housing, which is available for dual starter applications. In this case, a micro-lock switch must be connected to the circuit of the electric starter in order to protect the spring starter.

2. If the engine has only one bore in the flywheel housing, the spring starter can be used as a primary starter or back up starter.

Mechanical Starter Is The Ideal Solution For Engine Start Without External Power

The engine is the source of power, bringing power to modern society. While the engine must be started by a 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 it lacks external power, the engine is “dead”.

The mechanical starter is the ideal solution during the above situations. 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.

What is the 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 a 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.

How to fit a mechanical starter to the engine?
(1)Most of the flywheel housings have two bores. The 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 spring starter to the mounting bore when needed.

Advantages of mechanical spring starter.
Compared to an electric starter, the mechanical spring starter is maintenance-free. And compared to other means of starting, a spring starter requires no external system such as battery, cable, air compressor, fuel tank and so on. Cqstart spring starter is waterproof, anti-corrosion, and produces no sparks. With a natural anti-explosion structure, you can use it anywhere dangerous.
