Oil leakage in hydraulic oil filter of causes and solutions
Hydraulic oil filter can quickly remove the water, impurities and volatile (such as ammonia) and other harmful components in the oil, improve the quality of the oil and restore its performance. Ensure the normal operation of the hydraulic system.
However, hydraulic oil filter in the use of the process will also appear vacuum pump leakage phenomenon. Hydraulic oil vacuum pump oil leakage mainly occurred in the vacuum pump oil window, oil tank seal, motor bearing seal three positions, the main reason is that the vacuum pump used for too long and caused the aging of these parts, seal failure, resulting in oil leakage.
Oil leakage of the oil window of the hydraulic oil filter is caused by the aging of the oil window caused by the vacuum pump used for too long, or the aging and failure of the adhesive between the oil window and the oil tank, resulting in the leakage of the pump oil; The oil tank is connected with the motor through the adapter. There is a sealing ring at the junction of the oil tank and the adapter to seal the oil tank. If it ages, it can also cause oil leakage in the vacuum pump. There are two oil seals on the motor shaft: front oil seal and rear oil seal. Any aging failure will cause oil leakage. In addition, there is a felt pad on the adapter, which ACTS as a recovery pump oil, if it is full, the vacuum pump will also seep oil.
