Rexroth hydraulic pump maintenance

1. Choose the right hydraulic oil The hydraulic oil plays the role of transmitting pressure, lubricating, cooling and sealing in the Rexroth hydraulic pump. The improper selection of hydraulic oil is the main reason for the early failure and durability of the Rexroth hydraulic pump. The hydraulic oil should be selected according to the grade specified in the random “Instruction Manual“. Different grades of hydraulic oil cannot be mixed to prevent the hydraulic oil from chemically reacting and changing its performance. Dark brown, milky white, and odorous hydraulic oil is deteriorating oil and cannot be used. 2. Prevent solid impurities from mixing into the Rexroth hydraulic pump When refueling, when refueling, the staff must pay attention to using clean work clothes and gloves to prevent solid impurities and fibers from falling into the oil. The filling of hydraulic oil must be filtered by the filter trolley. In order to ensure the cleanliness of the oil, the solid trolley must be cleaned r
