HOPU LY Series Hydraulic Oil Filtration Cart Introduction
It is mainly used to filter water and impurities in aviation hydraulic oil, lubricant oil,transformer oil, turbine oil, diesel oil, and other waste industrial oils, and it can also use stainless steel materials to filter vegetable oil.
This portable oil filter machine is low cost and is easy to use, with small size and light weight. It is also widely used for oil filling and filtering for machine tools, vehicles, oil tanks, oil switch and mutual inductors.

This machine is composed of components such as a filter bed, oil pump, and coarse filter. The filter plate and filter frame are lined with filter paper or cloth as the filtering medium. The pressure of the compression device fixes the filter plate and filter frame into a separate filtering chamber, and the filter paper or cloth pressed between the filter plate and filter frame plays a filtering role. The high-precision BK-200 plate frame pressure oil filter (cast iron type) has the advantages of simple structure, easy operation, and low operating cost.
The plate and frame pressure oil filter (cast iron type) is specially designed for power plants, power stations, industrial and mining enterprises, lubricating oil warehouses, Machine tractor station, petroleum, chemical, metallurgical, national defense units, etc.

Working principle of plate and frame filter press
The plate and frame filter press is used for solid-liquid separation of sludge wastewater generated in various industries. Compared with its equivalent functional equipment, the plate and frame filter press has better treatment efficiency, and the moisture content of the sludge cake after pressure filtration is lower. The basic principle of its operation is that the filtering material flows through the filtering medium (filter cloth), the solid stays on the filter cloth, and gradually accumulates on the filter cloth to form a filtering mud cake. The filtrate partially permeates through the filter cloth, becoming a clear liquid without solids.

As the filtration process progresses, the filter cake filtration begins, the thickness of the mud cake gradually increases, and the filtration resistance increases. The longer the filtration time, the higher the separation efficiency. Specially designed filter cloth can intercept particles with a diameter less than 1 μ The particles of m. In addition to excellent separation efficiency and high solid content of the mud cake, the filter press can also provide further separation process: during the filtration process, it can effectively wash the filtered mud cake, so that valuable substances can be recovered and filtered mud cake with lower moisture content can be obtained.
