Insufficient coolant in MTU diesel generator cooling water tank

General generator rent common white smoke mechanical failure problem, the specific situation of the specific analysis, if there is any problem is better than the after-sales contact, if it can solve itself also need to be carried out under the after-sales guidance. If the above does not solve the problem of white or blue smoke in the generator, it can only be completely overhauled.

1. The cooling water temperature of the generator is too high

Usually, the radiator surface of the generator cooling water tank is not clean. The dusty environment is easy to plug the radiator surface, or when the unit is running, sundries are sucked to the water tank by the cooling fan to block the ventilation and make the heat dissipation poor.

Use water to clean the radiator surface or remove debris can be solved. Therefore, it is especially important to keep the environment clean in the equipment room.

2. The coolant in the generator cooling water box is insufficient.

It is necessary to check the cause of cooling water loss, and check whether the cooling water pipes of the cooling water tank and the fuselage leak. If there is leakage, it should be repaired immediately. Then refill the coolant to the normal level.

3. In the process of generator, after using for a long time, the cooling fan belt will gradually age and become inelastic or a belt fracture will cause the cooling fan to lose its normal blowing ability.

At this time, the cooling fan belt needs to be replaced again, and the whole group of belts should be replaced together instead of just one of them. There is a great difference in the elasticity of the old and new belts. When the generator is running, the cooling fan is subjected to large centrifugal force and air shear force. The elasticity difference between a group of belts is not easy to drive the cooling fan to run, and the fan blades are easy to lose balance. However, the matching between the cooling fan, the steel guard and the cooling water tank is fine, and the change of the balance degree may cause the fan to collide, and the last three devices will be damaged. In another case, the belt pulley bearing of the cooling fan sags after wear, causing belt relaxation, affecting the blowing ability. However, this phenomenon is relatively rare in the standby oil machine, as long as the usual maintenance of the cooling fan belt pulley bearing enough lubrication can be avoided.

4. The coolant in the cooling water box is insufficient.

This is due to the pump after a long time of internal gear wear leakage caused by. This fault is also less common in backup oil engines. In this case, contact the manufacturer to repair or replace the pump.

5, thermostat failure can not be opened, so that the cooling water temperature changes can not change the circulation path of cooling water, control the flow of cooling water into the cooling tank, to achieve the purpose of regulating the cooling intensity. The thermostat needs to be replaced.

6. The use of unqualified coolant makes the cooling water pipe accumulate scale, rust and other things to hinder the circulation of cooling water and cause the temperature rise.

For the use of coolant, use at least qualified tap water, preferably distilled, deionized or pure water. For the cooling system that has been seriously deposited or blocked, it is best to mix the volume of every 7 liters of cooling system with the proportion of 0.5 liters of detergent, and clean water. After starting and running for 90 minutes, the circulating cooling water shall be cleansed, and then the clean water shall be cleansed, so as to avoid the detergent remaining in the pipeline to corrode the pipeline.
