The role of Cummins coolant

Many serious faults occur in the repair reports received by generator set manufacturers, which are often caused by minor maintenance negligence and lack of professional inspection. For example: diesel oil storage tank, due to the condensation of water gas in the atmosphere at temperature changes, formed water drops attached to the inner wall of the tank, into diesel, resulting in excessive diesel water content, such diesel into the engine high pressure oil pump, will rust precision coupling parts - plunger, serious damage to the unit. Regular maintenance can avoid this problem.

Diesel generator sets are used as emergency standby power supply providers after mains failure and power failure. Most of the time, the units are in standby state. Once the power failure occurs, the units are required to "move and supply". Otherwise the standby unit will be meaningless! How can this be achieved? Practice has proved that strengthening daily maintenance is the most economical and effective method. Because the unit is static for a long time, various materials of the unit itself will have complex chemical and physical changes with oil, cooling water, diesel oil, air, etc., so as to "put" the unit bad.

When it comes to maintenance, generator manufacturers attach great importance to the selection of accessories. Coolant is one of the important parts needed for the maintenance of generator set. The diesel engine temperature will rise sharply due to the influence of diesel combustion during the operation of diesel generator. The high temperature environment will not only affect the improvement of the working efficiency of diesel generator, but also cause the occurrence of parts failure. Based on this, we need to cool the heated part, which involves the addition of coolant to the cooling system of diesel engine. What role does the coolant play in the operation of diesel generator set?

1. Anti-freezing effect

The temperature is too low to ensure that the diesel cooling system is not frozen, generally speaking, the commonly used coolant antifreezing temperature is between minus 20 degrees to 45 degrees, according to the actual needs of different regions to reasonable choice.

2, anti-boiling effect

It is guaranteed that premature boiling will not occur under high temperature conditions. The boiling point of coolant commonly used is 104 to 108 degrees. When the coolant is added to the cooling system and pressure is generated, its boiling point will be higher.

3, anticorrosive effect

Special coolant can reduce the corrosion of the cooling system, so as to avoid the cooling system corrosion caused by water leakage problems.

4, rust prevention

High quality coolant can prevent rust in the cooling system, which can lead to accelerated wear and reduced heat transfer efficiency.

5, anti-scale effect

Since the coolant uses deionized water, scaling and precipitation can be avoided to protect the engine.
