Hydraulic jacks usual maintenance methods are there? 1, the working level in the tank should always be kept in the center of the oil the subject line, to prevent pump cavitation. EHV refueling sync jack, use 120 mesh grease filter new oil filter out impurities. When frequently used filters cleaned once every two months, half a tank cleaning, and replace with new oil. 2, pump the normal operating temperature of 10`C-50`C. High oil temperature, cooling measures to be taken or stop the pump, when the oil temperature is too low, or low heating measures need to be taken to improve the operation of the oil. 3, before the motor is started, the need to change the valve position in half. Jogging several jack the price, to prevent high-pressure pump suction air, before using air excluded. 4, the pump it is set at the factory to work under pressure shall be arbitrarily increased. Single acting hollow (feedthrough) jack widely used in construction, bridge construction, road and railway construction, power station construction, equipment upgrade jack manufacturers, mechanical demolition, the hollow jack with a pull-up, the center hole for the wire, steel, etc. pass through the center of the empty can be processed according to user needs, according to different user requirements specification jack, different stroke hollow jack, optional hydraulic station, single-acting manual pump.
