lubricating oil filter filtration process
The filters are cylindrical in shape and arranged vertically for easy maintenance.
The oil filtering equipment is equipped with two or more filters.
The principle of streamline filtration is adopted. The oil to be filtered flows from the outside to the inside of the filter. Dust particles less than 5 microns cannot pass through the outside of the filter. The filter is made of stainless steel and can be used repeatedly;
A pressure gauge is installed on the filter to monitor the pressure difference across the filter. The filter must be cleaned every time the pressure difference on the filter is greater than 0.3MPa at normal working temperature.
Lubricating oil filtration refers to the three-stage filtration of wheeled oil filter (oil filtering trolley). The wheeled oil filter adopts filter element filtration, and its operation principle is simple.
The three-stage filtering effect of lubricating oil is simple in principle. This equipment can only filter mechanical impurities, and can not remove moisture, harmful gases and other substances in the oil. The filtering accuracy can be selected according to customer requirements. The high precision can reach 1 μ M.
The accuracy of three-stage filtration is 10 μ m, 5 μ m and 3 μ m (conventional configuration precision). Each tank has different eyes. According to the filtering accuracy of the filter element, the tank adopts different pressure to effectively increase the service life of the filter element. (the multi-level UG Eulerian is determined according to the filtering stage and filtering accuracy)
Three stage filtration flow of lubricating oil: between 10L / min and 500L / min (more than 500L / min is called filtration system). The filtration flow is relative to the capacity of new oil pumping and refueling. Generally, the speed of filtering oil is about? Of the flow rate (depending on the degree of oil pollution)
Service life of filter element: the service life is usually about 10 tons of oil according to the pollution degree of oil. Clean or replace once.
Features: low price, high filtering accuracy, easy to move, use according to the site situation, low cost of consumables.
The water and gas in the air seeps into the oil due to the leakage of lubricating system, loose sealing, long-term heat load of oil and open oil storage, which results in water and gas in lubricating oil.
Because of the leakage of the lubrication system, the particles in the air or the system wear and fall off, and the lubricating oil works under high temperature and water for a long time, it will inevitably lead to the cracking and deterioration of some oil and the precipitation of colloidal substances.
Hazards of water, gas and impurities in lubricating oil:
1. The oil is rapidly oxidized and deteriorated to form acidic substances and corrode the metal contact surface;
2. The additive precipitation in the oil failed, the thickness of oil lubrication film decreased, and the wear of mechanical contact surface increased;
3. The lubricating, cooling and flowing properties of the oil are reduced, and the fatigue of metal surface is accelerated;
The blocking under the ice crystal causes the element to form low temperature;
5. The response of oil system is slow with irregular action, and the conductivity is reduced;
6. The oil pump and power equipment are damaged by cavitation.
In this case, an original solution: the advantages of oil change need not be said, but the fatal disadvantage is that the cost of oil change is too high. The recommended solution: for high-precision lubricating oil filtration, you can buy our company to carry out high-precision filtration on the lubricating oil filter.
