What Are The Causes And Judgment Methods Of The Main Oil Cylinder

The main oil cylinder of the fly ash brick machine is scratched because the equipment is not maintained and maintained for a long time under frequent and high-intensity working conditions, and it accumulates for a long time. The bricks cannot reach the corresponding density and are scrapped. The proportional variable piston pump is selected. Within the pressure and flow range, the main oil cylinder can adjust the pressure and flow according to the needs, and use the pressure retention to control the molding of the brick. The system reduces hydraulic shock by first releasing pressure and then reversing, increasing the oil temperature and prolonging the service life of the main cylinder. A hydraulic control check valve is added to ensure that the slider will not automatically drop with the failure of the balance valve. When the balance valve and the hydraulic control check valve fail together, the safety valve is a safety protection function.

The decompression problem caused by accidental scratches is sudden, and there is no gradual process of normal wear and decompression. The formation of accidental scratches and the service life of the fire brick machine have no inevitable impact, most of which occur during equipment installation or In a short period of time after disassembly, impurities are deposited in the main cylinder due to the unclean hydraulic system, which will cause local scratches under high-pressure movement. Oil doesn't work.

The scratches on the main cylinder occur inside the components. It is very difficult for us to find out when there is no fault. Once the fault occurs and then repair it, the loss will be huge. It is necessary to do a good job of prevention and judgment in advance. Summary judgment method:

1. Under the premise of normal operation of the fly ash brick machine, adjust the hydraulic system to make the main oil cylinder in a high pressure state, measure the maximum pressure and compare the rated pressure, if the difference is too large, it means that the main oil cylinder has been scratched;

2. Stop the automatic control system, keep the high pressure mode, open the oil return pipe of the main oil cylinder at a reasonable position, and observe the leakage of hydraulic oil in the oil return pipe after the internal oil pressure is released. If it exceeds the maximum allowable leakage amount, it means that the inner cavity wall of the main oil cylinder has serious wear and tear Or some accidental scratches, it is necessary to stop and repair the main cylinder.

Scratches will damage the main oil cylinder of the fly ash brick machine. In addition to the maintenance and maintenance of the equipment, we also need to check the main oil cylinder regularly, and use the above judgment method to check to avoid serious scratches. The gray brick machine is not working properly.
