The oil pressure of Weichai engine is too high

1. There are many reasons why the pressure of Laidong diesel engine is too high. It is recommended that you go to the repair shop to check: the advantages of diesel engine are large torque and good economic performance.

2. The pressure of Weichai oil is too high. In this way, in this way, under the high temperature season or severe wear of the engine, the choice of high-viscosity oil is conducive to the formation of oil film and reduce engine wear.

3. If the oil pressure is too high, it will also cause oil leakage on the static joint surface of the diesel generator. The paper pads are not qualified. The paper pads of diesel generators are generally made of cow card paper, some are purchased, and some are homemade.

The oil pressure is too high

The reasons why the engine oil pressure of the vehicle is too high are: 1. The engine oil label used is inconsistent with the engine. The oil filter of the engine has not been replaced for a long time. The fuel injection of the vehicle nozzle is too large. The crankshaft bearing of the vehicle is faulty.

The oil pressure gauge or sensor is short-circuited. The reason why the oil pressure of the car engine is too high: the oil suitable for the region or season is not used according to the regulations, because the oil viscosity is too high.As a result, the oil supply pressure is too high, the pressure limit valves of the main and secondary oil channels fail, so that the pressure limit valve cannot be turned on in a timely manner.

The reason why the oil pressure is too high may be that the oil viscosity is too high, the oil pressure sensor fails, the pressure limit valve is improperly adjusted, etc. Oil is known as the blood of the engine. Oil not only plays a lubricating role in the engine, but also plays the role of heat dissipation, cleaning and sealing.

The reasons why the oil pressure is too high: first, the viscosity of the oil is too low; second, the oil filter or the oil filter element is blocked; third, the spring force of the pressure limiting valve and the oil return valve is weakened or broken, or the valve joint surface is not tightly sealed, resulting in oil leakage and pressure relief; fourth, the gap between the main bearing or connecting rod bearing is too large; fifth, the oil pump is not easy to use.

The reason for excessive oil pressure: failure to use suitable for local or seasonalOil, the viscosity of the oil is too high, causing the oil supply pressure to be too high, and the pressure-limiting valve of the main and secondary oil routes fails, resulting in the pressure-limiting valve not being able to open in time for backflow and depressurization. The oil channel from the main oil channel and the auxiliary oil channel to the lubricated surface is blocked.

The reason why the engine oil pressure is too high

1. The oil pressure limiting valve is improperly adjusted; the oil is too dirty and the oil is blocked; the oil pressure gauge or sensor is short-circuited. The reason for the high pressure of automobile engine oil: the oil suitable for the region or season is not used according to the regulations, the viscosity of the oil is too high, and the oil supply pressure is too high. The pressure-limiting valves of the main and secondary oil channels failed, and the pressure-limiting valves could not be opened in time for backflow and decompression.

2. The reason why the oil pressure is too high: 1 the viscosity of the oil is too high; 2 the main oil channel of the oil is blocked;3 The oil pressure limiting valve is improperly adjusted; 4 The oil is too dirty to block the oil channel; 5 The oil pressure gauge or sensor is short-circuited.

3. The main reason why the oil pressure is too high: 1 The oil selection is unreasonable. For example, the use of summer oil in winter not only makes it difficult to start, but also affects the work of the lubrication system. 2 The oil filter or main oil channel is blocked and the pressure to open the return valve is too high.

What will happen if the engine oil pressure is too high

1. If the engine oil pressure is too high, it is easy to break the gasket or oil seal, resulting in leakage faults, such as engine oil blockage, oil seals in front and rear of the crankshaft, oil pipe joints, etc., which will be caused by excessive oil pressure Raw oil leakage.

2. The main reason why the oil pressure is too high: 1 The selection of oil is unreasonable.For example, the use of summer oil in winter not only makes it difficult to start, but also affects the work of the lubrication system. 2 The oil filter or main oil channel is blocked and the pressure to open the return valve is too high.

3. Too high oil pressure is easy to cause oil leakage, which may cause the oil filter to burst or fall off. Engine oil blockage, front and rear oil seals of the crankshaft, etc. Oil leakage will occur due to high oil pressure; sometimes, excessive oil pressure will cause the oil filter to burst or fall off, resulting in a large amount of oil leakage, which is very dangerous in engine operation.

4. First of all, excessive oil pressure will cause oil leakage. When the oil pressure exceeds the design range, the oil sealing ring may fail, resulting in oil leakage. If the oil leakage is serious, it may cause the engine to lose lubrication, causing serious wear or failure of the machine parts.Secondly, excessive oil pressure will affect the fuel consumption of the engine.

5. And once the oil pressure is really too high, it is likely that the fuel tank will crack, or even leak oil in serious cases, so the natural fuel consumption will also increase. And if it is in summer, once the temperature is too high, it will cause more serious consequences such as spontaneous combustion.
