The lubricating oil filter equipment is on the suction pipe of the hydraulic pump. This equipment method requires the filter to have a large oil permeability and small resistance. Therefore, a coarse filter with a lower filtering accuracy is generally used. The intention is to maintain the hydraulic pump. The oil suction filter equipment is on the oil return pipe. This equipment method can often remove impurities in the oil. To prevent the oil from flowing back to the tank when the filter is blocked, a safety valve should be connected in parallel. Due to the low pressure of the return pipe, a less powerful filter can be used. The equipment is on the hydraulic pump's oil pipeline. This equipment method maintains components other than hydraulic pumps and relief valves. Fine filters are generally used. Because the filter operates under high pressure, the filter element and housing should be able to accept the operating pressure and impact pressure of the system. In order to avoid overloading the pump or damaging the filter element when the filter is clogged, a clogging indicating device or a safety valve can be installed in parallel on the pressure oil circuit. The equipment is in front of important components, in front of important components, and can be equipped with an independent fine filter as required to ensure the normal operation of these components.
Lubricating oil filter, the internal space is more fully used, eliminating the waste of space in the traditional side-entry type. Opening the upper cover can quickly and easily replace the filter bag. Unlike the traditional side-entry type, the filter bag must be removed and the ring can be replaced. The timing of secondary pollution is that the liquid inlet pipe is wide and smooth, and the inside of the top cover is a horn type. After the liquid enters, it can actively divide the pressure, have a small impact on the filter bag, and filter faster and more securely.
The lubricating oil used in the lubrication process must be pure and free of impurities, otherwise it will seriously endanger the machine, such as conflict surface fuzzing, jamming and clogging of lubrication channels. Therefore, it is necessary to use filtering equipment to filter the suspended impurities in the oil Off. Generally, the filtering equipment is separated by using various porous objects, barriers, or applying different density of oil and impurities and using centrifugal force. The filtering materials used are cotton, felt, metal mesh and perforated metal foil. There are many types of filters, and some commonly used ones are now introduced.
