Maintainance
The Carter excavator hydraulic pump is an important part of the excavator hydraulic system. It is responsible for providing hydraulic pressure to drive the various hydraulic actuators of the excavator. The following are some common maintenance methods for Carter excavator hydraulic pumps:
Regularly replace the hydraulic oil: Regularly replacing the hydraulic oil in the hydraulic system is a very important maintenance measure. Hydraulic oil will be contaminated and aged during use, and regular replacement can keep the hydraulic system running normally. Please refer to the operation manual of the Carter excavator to understand the correct type of hydraulic oil and replacement cycle.
Check the hydraulic pump seal: Regularly check the seals of the hydraulic pump, including shaft seals, sealing rings, etc. If any leakage or wear is found, it should be replaced in time.
Clean the hydraulic pump air inlet and filter: Regularly clean the hydraulic pump air inlet and filter to prevent dust, impurities, etc. from entering the hydraulic system and causing damage.
Check the working pressure of the hydraulic pump: Regularly check the working pressure of the hydraulic pump to ensure that it is operating within the normal range. If the pressure is found to be abnormal, it should be checked and repaired in time.
Regularly check the noise and vibration of the hydraulic pump: Abnormal noise and vibration may be a sign of problems with the hydraulic pump, which requires timely inspection and repair.
Pay attention to the working temperature of the hydraulic pump: The working temperature of the hydraulic pump should be kept within the normal range. Excessive temperatures may cause aging of the hydraulic oil and damage to pump parts. If the operating temperature of the hydraulic pump rises abnormally, the cause should be found and resolved.
