Causes Cummins generator set coolant not to circulate

Causes Cummins generator set coolant to not circulate diesel generator | diesel generator price / 2018-07-17
Cummins diesel generator block cylinder design is sturdy and durable, with low vibration and low noise; in-line six-cylinder four-stroke, stable operation and high efficiency; replace wet cylinder liner, long life and convenient maintenance; two cylinders and one cover, four valves per cylinder, advance Fully gas, forced water cooling, low heat radiation and excellent performance.

In the process of using diesel generator sets, the problem often arises that the coolant of the generator set does not circulate, which leads to the failure of the diesel generator set to operate normally, which leads to a significant reduction in work efficiency. The genset research center takes the Cummins generator set as an example. For the majority of users to share the reasons and solutions for the coolant does not circulate.

The main reasons for the non-circulation of the Cummins generator set coolant are:

1. Cummins diesel generator pump failure. Check if the pump is working well. If the pump drive pinion wear is too limited, it means that the pump has no effect and needs to be replaced before it can be cycled normally.

2. The liquid level of the Cummins diesel generator set coolant is too low or does not meet the requirements. If the liquid level is too low, the temperature of the coolant will increase directly, so that the coolant will not circulate. The coolant is 50% antifreeze + 50% softened water + DCA4 according to the regulations. If it does not meet the requirements, the pipeline will be blocked and the pipe wall will be produced. Rust prevents the coolant from circulating properly.

3. The thermostat of Cummins diesel generator set is faulty. A thermostat is installed in the combustion chamber of the engine to control the temperature of the engine combustion chamber. The thermostat must be fully opened at the specified temperature to facilitate small circulation. If there is no thermostat, the coolant cannot maintain the circulating temperature, and a low temperature alarm may occur. .

Cummins generator set engine uses gear centrifugal pump to force water cooling, large flow channel design, good cooling effect, which can effectively reduce heat radiation and noise. A unique spin-on water filter that prevents rust and corrosion, controls acidity and removes impurities.

Coupling Transform:  It is true that the power consumption rate of T-BFP is higher to M-BFP, so there is a requirement to transform the M-BFP, in order to decrease the station service power consumption rate. The methods of transformation including the followings:

coupling connected directly, frequency control, external lube oil station

replace gearbox, transform booster pump add new motor

tretain coupling function, external oil station recover oil system

This transform project could save standard coal 3594t every year for a 300MW unit power plant. ( Ningxia Maliantai Power Plant 1# unit has finished in 2012 ).
