The second purpose is to clean after the first installation of the remaining dirt jack prices, such as sealing pieces, different quality of wash oil and anti-rust oil and wash down inside the casting sand, metal powder run-down, and then second installation consisting of double-acting jack formal system to ensure smooth adjustment formal commissioning and put into normal operation. Cleaning time according to the complexity of the hydraulic jacks, the degree of contamination of the desired filtration precision and hydraulic jacks varies. After reaching a predetermined cleaning time according the type and quantity of impurities through the filter in the filter, to determine whether the end of the second cleaning purpose cleaning. 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, use 120 mesh grease filter new oil filter out impurities. Often use hydraulic jacks, filter cleaned once every two months, six months to clean the tank once a jack, 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. 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.
