How To Solve The Problem Of High Engine Temperature Of Sanitary Rotary Vane Pump

Sanitary Rotary Lobe Pump How to solve the problem of high engine temperature:

Reasons for high engine temperature of sanitary rotary vane pump

1. Water leakage in the cooling system or insufficient cooling water;

2. Inaccurate or malfunctioning water temperature gauge;

3. Too much scale in the cooling system, poor heat dissipation effect;

4. The radiator guard net or radiator core ventilation duct is blocked by debris, resulting in poor heat dissipation;

5. The water pump and fan belt are too loose or broken;

6. The water pump is damaged, the fan blades are reversed or deformed, and the wind ring is damaged;

7. The thermostat is damaged in the main valve closed position;

8. The engine is overloaded for a long time and the fuel supply time is too late.

Methods to eliminate the high temperature of the sanitary rotary vane pump engine

When the engine has a high water temperature fault during operation, you should pay attention to observe the fault phenomenon, find out the cause and eliminate it. First, check whether the water temperature gauge is out of order. If it is inaccurate or out of order, replace it. Then check whether the water tank is short of water, whether the water inlet pipe and radiator are broken or leaking. In addition to direct observation from the outside, you can also use the method of pumping to check the leaking part. The leaking part of the radiator can be repaired by soldering. If a radiator pipe is severely broken, the two ends can be clamped and blocked. If a slight leak is found during work, it can be blocked with soap and repaired after parking.

If it is not due to the above reasons, further check whether the engine housing has cracks, whether the water blocking ring is damaged, and whether the water pump drain hole is leaking. Finally, check whether the exhaust valve of the radiator cap is invalid. If it is invalid, replace it.

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

1. Sudden water temperature is too high. First check whether the radiator is overheated. If the radiator temperature is too high, it means that the cylinder gasket is damaged. At this time, pay attention to check whether the upper plane of the engine body and the joint surface of the cylinder head are seriously warped and deformed. If deformed, it should be repaired in time. If the radiator temperature is not high, it means that the cooling water circulation is poor. Check whether the fan belt is broken or seriously slipped. If it is normal, check whether the radiator outlet pipe is sucked flat and whether the inner hole is delaminated and blocked. Find out the cause and eliminate it. The emergency method is to put a properly large spring support in the sucked pipe. Check whether the expansion tube of the thermostat is broken. If it is broken, it should be replaced. If the thermostat is normal, it means that the diaphragm pump is damaged. The water pump should be carefully checked and repaired.

2. Non-sudden water temperature is too high. For the phenomenon of excessive temperature that does not appear suddenly, the engine speed should be increased to observe whether the water inlet is overflowing, and pay attention to whether it is a large amount or a small amount of overflow. If there is a large amount of overflow and the radiator temperature is uneven, it means that some cooling pipes are blocked, which should be paid more attention to in the cold winter. When the water inlet overflows a small amount of water and the engine temperature is low at the beginning and high at the end, it means that the water distribution pipe is damaged or blocked and should be replaced in time. If it is not the above reasons, it may be that there is too much scale in the cooling system and the water channel is not smooth. If water does not overflow at the water inlet, the cooling system appearance and the engine mechanical part should be carefully inspected and analyzed. First, check whether the shutter is closed or the opening is insufficient and whether the fan is rotating normally. 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 blades, bend the blade head appropriately or change the fan blades. If the engine is still overheating under normal cooling system conditions, the reasons for use should be considered.

In short, there are many reasons for the overheating of the sanitary rotary vane pump engine, and the above methods can be flexibly used to check and eliminate them according to the specific situation.
