Stainless steel electric diaphragm pump engine temperature is too high elimination method

When the engine in the work of high water temperature fault, should pay attention to observe the fault phenomenon, find out the reason to eliminate. First of all, check whether the water temperature table failure, if not allowed or failure should be replaced; Then check whether the water tank, water inlet pipe, radiator is broken water leakage, in addition to direct observation from the outside, can also be used to check the method of air leakage. The radiator can be repaired by tin welding. If a heat pipe is broken heavily, the two ends can be clamped flat and blocked. Found in the work of slight water leakage, can be blocked by soap, to be stopped after repair.

If not for the above reasons, should further check whether there is a crack in the engine housing, whether the water resistance ring is damaged, but also to check whether the pump drainage hole water leakage. Check whether the exhaust valve of the radiator cap is invalid, if the loss of effect is replaced.

If it is not a cooling water leakage problem, the fault should be analyzed and eliminated in two cases.

1. The water temperature is suddenly too high. First check whether the radiator is overheating. If the temperature of the radiator is too high, it indicates that the cylinder pad is washed out. At this time, pay attention to check whether the plane on the body and the cylinder head are seriously warped and deformed. If the temperature of the radiator is not high, it indicates that the cooling water circulation is poor. Check whether the fan belt is broken or seriously skidded. If normal, then check whether the radiator outlet pipe is sucked deflated, whether the inner hole is blocked by delamination, find out the cause to be eliminated, the emergency way is to put the appropriate spring support in the deflated pipe. Check again whether the expansion cylinder of the thermostat is broken, and the rupture should be replaced. If the thermostat is normal, it indicates that the diaphragm pump is damaged, and the pump should be carefully checked and repaired.

2. Non-accidental excessive water temperature. For the phenomenon that the temperature is not suddenly too high, the engine speed should be improved to observe whether the water inlet is turning over, and pay attention to whether it is a large amount or a small amount of turning over. If a lot of water, and the radiator temperature is uneven, it means that some cooling pipe is blocked, in the cold winter should pay more attention to. When the water inlet is turned over a little and the engine temperature is low before and high after, it indicates that the water distribution pipe has been damaged or blocked, and should be replaced in time. If not for the above reasons, the cooling system may be too much scale, waterways are not smooth. If the water does not turn over at the water inlet, the surface of the cooling system and the mechanical part of the engine should be carefully checked and analyzed. First check whether the shutters are closed or not open enough to see if the fan is running properly. If everything is normal and the engine is still overheating, check the fan air volume. If the air volume is insufficient, adjust the Angle of the fan blade and bend or change the fan blade. In the cooling system under normal conditions, the engine is still overheating, should consider the use of reasons.
