1, correct the rotation direction of the prime mover.
Correcting the rotation direction of the prime mover is a method to solve the problem of no pressure in hydraulic oil pump. The wrong rotation direction of the prime mover may cause the hydraulic pump to fail to work normally, so it is necessary to correct the rotation direction of the prime mover. Before correcting the rotation direction of the prime mover, it is necessary to determine whether the rotation direction of the prime mover is correct. It can usually be judged by observing the rotation trace of the prime mover.
2. Reinstall the gearbox key of the hydraulic pump.
Before reinstalling the drive key of hydraulic pump, it is necessary to check whether the drive key falls off or is loose. If you find something wrong with the drive key, you need to remove it. When removing the transmission key, you must use appropriate tools, such as a screwdriver or wrench, to avoid damage or deformation of the transmission key due to strong force or improper tools.
3. Clean and replace the oil filter.
Cleaning and replacing the oil filter is one of the common methods to solve the problem of no pressure in hydraulic oil pump. The function of oil filter is to filter impurities and particles in hydraulic oil and prevent them from entering the hydraulic system and causing blockage or wear. If the oil filter is blocked or damaged, the hydraulic oil cannot pass through the oil filter, resulting in no pressure in the hydraulic oil pump.
4, come on to the lowest oil mark above.
Replenishing oil above the lowest oil standard is a method to solve the problem of no pressure of hydraulic oil pump. If the hydraulic oil level is too low, the hydraulic oil pump may not work normally, so it is necessary to replenish the oil above the minimum oil level.
5. Clean the pipeline and replace the sealing ring.
Cleaning the pipeline and replacing the sealing ring is one of the effective methods to solve the problem of no pressure of hydraulic oil pump. The pipeline and sealing ring of hydraulic system are the key components of hydraulic oil flow and sealing. If the pipeline is blocked or the sealing ring is damaged, the hydraulic oil will not flow or leak normally, resulting in no pressure in the hydraulic oil pump.
