Before installation and operation of hydraulic jacks why should be cleaned before installation of hydraulic jacks and running must be rigorous cleaning, cleaning purpose is to remove the hydraulic jack inside the welding slag, metal powder, fragments of the sealing material, and fully maintained within the external jack clean, you can make a hydraulic jack to work, reduce unnecessary trouble, hydraulic jacks that cleaning work, several steps it is worthy of our consideration of the issue, the following, we will work on the hydraulic jacks to a preliminary look clean. The first wash after hydraulic jacks are pre-installed (try fitting tube) jack, remove all of the disintegration of the pipeline carried. Should ensure that the first cleaning, obviously, may be washed and powder metal burr jack manufacturers, sand dust, paint, iron oxide, oil, cotton, rubber and dirt all carefully cleaned a lot of clean, otherwise do not allow the first installation of hydraulic jacks. The first cleaning time with hydraulic jacks size, the degree of accuracy required filter pollution and hydraulic jacks may be. Generally 1 to 2 days and nights. After reaching a predetermined cleaning time, according to the various types and quantity of impurity filter in the filter, and then determine whether or not the end of the cleaning work. 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 quality jacks, 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 hydraulic jacks, 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.
