Hydraulic As a widely used technique in the future but there is a broad prospect. With the further development of the computer, the hydraulic control system and intelligent control technology, computer technology, control technology together, so it can play a role in more occasions, also can be more compact, more flexible completion expected control tasks. 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. When refueling electric hydraulic jacks, use 120 mesh grease filter new oil filter out impurities. Often used when manual off jack, oil filter 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 thin jack, 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. Jog a few times 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.
