What will happen if the car unloading valve is installed in reverse

The function of the crank connecting rod mechanism is to provide a combustion place, and convert the expansion pressure of the gas acting on the top of the piston after fuel combustion into the torque of the crankshaft rotation, and continuously output power. The crank linkage mechanism is the main moving part of the engine to realize the working cycle and complete the energy conversion.

What kind of forklift is Longgong's on the left side of the engine, and the diesel pump is on the side, and if it breaks, it may be slow or even not at all.

1.Diagnose faults with the method of looking and asking Doctors need to "see, hear, ask, and see" when seeing a doctor, and the same is true for car fault diagnosis, in which looking and asking is an effective way to quickly diagnose car faults. When a car breaks down and needs to be diagnosed, when the repairman sees the car for the first time, he should make a preliminary judgment on the form and service life of the car, and the form of the car can be understood from the appearance, which is very.

When the driver starts the engine and puts the operating lever in neutral mode, the main pump outputs hydraulic oil and returns directly to the fuel tank through the Yedozhao relief valve, and the unloading pressure is 3MPa. If the valve core of the relief valve is not closed tightly due to the dirty oil, when the machine is operating, the output oil of the main pump will pass through the relief valve and go straight to the oil tank, so that the system cannot establish high pressure; Similarly, if the 0-ring on the relief valve that is used to block the connection of the PLS pressure oil to the tank is damaged, it will also cause the main pump hydraulic oil to flow directly back to the tank.

The reason for the multi-way valve, probably, the unloading valve is broken, most of them are because the boom is very slow to retract, there is no force, and it is useless to increase the throttle.

There are two types of air inlets for screw compressors: unloading valves and inlet valves. The unloading valve you said can't be opened should be a problem with the sealing ring of the unloading valve, and the unloading valve can be opened. Take a look at the wear of the two sealing rings and the aging of the O-ring under the sealing ring.

The other type of intake valve is mostly a solenoid valve problem or dirt cleaning.

Clean the relief valve and check the use of the springs.

Unloading oil leakage, then the shutdown must be oil leakage, check whether the unloading solenoid valve is blocked, and then check whether the inlet valve is closed when unloading. Here's the problem.

Unloading valves. On the pipeline, just think about it, and it's okay.
