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), the pipeline carried all removed disintegration. Should ensure that the first cleaning, obviously, could wash away the metal burrs and powder, sand dust, paint, iron oxide, oil, cotton thin jack, particles 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. What hydraulic jacks works? Big cylinder and piston composed of large hydraulic cylinders lift jack manufacturers, lever handle, a small cylinder, small piston, consisting of a one-way manual pump. Lift the handle so small as the piston moves upward, the lower end of the small piston oil chamber volume increases, the formation of a partial vacuum, then the one-way valve is opened, the suction through the suction pipe from the tank; 320 jack handle firmly pressing down on the small piston down jacks, Under the small piston chamber pressure increases, the one-way valve is closed, one-way valve is opened, the oil through the pipeline input lift cylinder chamber, forcing large living moves up, the top lifting objects. Lifting the handle suction again, the check valve closes automatically, so the oil can not turn the clock back, so as to ensure the weight does not fall on their own. Pulling the handle back and forth constantly, you can keep the oil hydraulic lifting cylinder into the lower chamber, so that the weight is gradually rising. If you open the valve, the lower chamber of the lifting cylinder oil through the pipeline, shut-off valve back into the tank, the weight moves downward, which is the working principle of hydraulic jacks.
