Many people may know that starting a diesel engine requires a starter, but they do not know that a diesel engine needs a backup starter. Under normal circumstances, the diesel engine can be started by the electric motor, but under special conditions, or the electric motor is out of power, the help of a backup starter is needed. Common backup starters include spring starters, air motors, and hydraulic motors.

Because of their excellent performance and wide range of applications, spring starters stand out among many diesel engines starting equipment and have become the most popular diesel engine spare starting parts.

Now let’s talk about 3 things you must know about Spring Starter.

Not only suitable for 4-20L large displacement diesel engines

At present, most spring starters on the market can be applied to 4-30L diesel engines. But this is not absolute. To be able to start a large-displacement engine, it is necessary to manufacture a suitable spring starter for a larger-displacement engine. With the continuous advancement of technology, new challenges also follow.

Used in diesel engines up to 50L

Cqstart spring starter can already provide reliable starting support for 30-50L engines. The Cqstart spring starter can already provide reliable starting support for 30-50L engines. Cqstart spring starter has a variety of combinations to start, according to different needs, provides different combinations of programs. And for emergency starting of large units, the cost of spring starters is much lower than other starting methods such as hydraulics. And can be repeated many times to start.

Applied to diesel engine parts below 2L

The spring energy storage start is especially suitable for the engine under emergency environmental conditions because, with its help, the engine can only be started by manpower. Due to the emergency environment of the engine, its battery often encounters the situation of battery shortage due to long-term storage, resulting in insufficient starting ability of the electric motor, making the entire engine system unable to start and running successfully.

Because of some small emergency diesel engines due to their special use environment (need to meet long-term storage characteristics, reliable starting ability, explosion-proof, etc.), the use of spring starters has become the best starting solution.

The 7 series of Cqstart spring starter is a unique starting device designed for starters below 2L.

Special application scenarios

Since the spring starter uses a disc spring as a medium for storing energy, it does not require batteries, compressed air, or hydraulic drive. It can be used in more demanding application scenarios. Such as special environments such as coal mines, oil fields, and chemical plants.

The spring starter adopts a cavity and transmission mechanism made of special alloy. The unique and simple structure design prevents sparks or radiation during use, and the structure is firm and reliable. Therefore, it is also suitable for occasions that are sensitive to sparks or difficult to maintain.

The angle of the rotating shaft can be adjusted freely

Because the spring starter is operated by a person shaking the handle, the spring is compressed, and then the torque and speed are released to the diesel flywheel to start the engine. 

The spring starter can be adjusted to the most comfortable angle for the user during installation to make the operation more in line with the user’s habits. Because for starting a large diesel engine, the disc spring of the hand-cranked starter will also be larger, and it will be more laborious when using the starter.

Although the spring starter does not use particularly advanced technology and does not use any modern energy, it only needs manpower to operate it, but it is the best starter under emergency conditions. Because it is not affected by environmental conditions (including harsh conditions), it can operate normally. Cqstart can be your most reliable spring starter provider, we are professionals in this field for decades, please do not hesitate to contact us if you are in need of a set of your own spring starter.
