Double-tube mesh filter for use in thin oil lubrication systems to filter lubricants of various viscosities. It is the primary equipment for cleaning the lubrication system. The medium viscosity grade used is N22 to N320. Double-tube mesh filter, there are two sets of filter devices, one set of work, one set can be cleaned and spared, adapt to the characteristics of continuous operation of the host. It is necessary to put the filter device into operation or in the state of cleaning standby, as long as the handle of the reversing valve is operated.

a double-cylinder mesh filter, comprising: two filtering devices, wherein a reversing valve is disposed between the two filtering devices, and the reversing valve is provided with an oil inlet port and an oil outlet port, and the A reversing handle is disposed on the top of the valve, and the side wall of the filtering device is provided with an oil drain plug. The utility model has the advantages that the effect of filtering dirt and impurities is good, and the cleanness of the lubricating oil is also improved, the structure is simple, the use is convenient, and the performance is stable.

Applicable to the thin oil lubrication system with a nominal pressure of 0.63MPa, which is used to filter the dirt and impurities in the lubricating oil. Because it is equipped with a magnetic core inside, it can also adsorb ferromagnetic particles (this kind of particles can pass through the filter element) to avoid mechanical friction. Sub-premature wear; superior in performance to general filters.

Instructions for use

1. When the inlet and outlet pressure difference is ≥0.05MPa, the filter device should be stopped, and the filter core block should be taken out for cleaning (including the cylinder).

2. When the filtration accuracy does not meet the requirements, stop the filter device and replace the filter.

3. During the operation of the filter, the reversing valve must not be rotated at will.
