The kcb200 gear pump is a complete system. There will be some faults during the operation, and the fault causes and solutions are briefly summarized.
One of the faults:
KCB gear pump is not draining at all. The reason may be that the suction height is too high. At this time, it is necessary to reduce the height or reduce the elbow valve. Botaibang may also be blocked by the suction pipe. It is only necessary to clean the pipe, or it is inhaled. If the pipe leaks, you need to press or replace the flange gasket.
The second fault:
KCB gear pump is not enough liquid discharge, the possible reasons include partial blockage of the suction pipe need to be cleaned, there is debris in the suction or discharge valve, and the suction and discharge valve needs to be cleaned. If there is gas in the inflation chamber, the venting valve core needs to be vented. If the oil in the oil-filled chamber is insufficient or too much, the oil will be added or reduced. If the compensation valve or the safety valve leaks, the valve needs to be ground. If the pump valve is damaged, it needs to be repaired or replaced. If the speed is insufficient, check the motor." =_blank> Machine voltage.
The third fault:
KCB gear pump is unstable in discharge pressure. For reasons of analysis, if there is any debris in the suction valve or the discharge valve, then the suction and exhaust valve should be cleaned. If the oil is leaking at the connection of the discharge pipe, only the screw at the joint, the safety valve or the compensation valve should be tightened. If you fail, you can adjust it.
The fourth fault:
The measurement accuracy is not enough. The reason is that there is residual gas in the oil filling chamber. In this case, manual oil supply is required to make the safety valve jump open and exhaust; if the safety valve or the compensation valve fails, the adjustment can be made; if the plunger seal leaks oil, it will be adjusted or Replace the sealing ring; the diaphragm piece needs to be replaced by the diaphragm; the suction valve or the discharge valve also needs to be replaced with new parts; if the motor speed is unstable, the power frequency and voltage are stabilized.
The fifth fault:
KCB gear pump has impact sound during operation. The cause analysis may be loose or severe wear of the transmission parts. At this time, it will be tightened or replaced. If the suction height is too high, it will cause impact sound. At this time, the installation height will be lowered. If the suction pipe leaks, it will be pressed. Tightly inhaling the flange; the amount of oil in the diaphragm chamber is too much, the light pressure compensating valve is used to drain the oil when it is artificial; the air inside the medium will also affect; the diameter of the suction pipe is too small to increase.
