Full-automatic drainage type centrifugal oil purification device

Abstract

The invention discloses an automatic drainage device which is arranged on the lower portion of a centrifugal barrel body and distributed symmetrically with respect to a center axis. The automatic drainage device comprises a shell with a cavity. A floater is mounted in the shell. A balance spring is arranged between the top end of the floater and the top end of the shell, and the top end of the floater and the top end of the shell are connected through the balance spring. An end cover is arranged at the lower end of the inside of the shell and is mounted at the bottom of the shell through a fastening clamp spring. A water outlet is formed in the end cover. The bottom of the floater and the end cover are matched in structure. An abutting block matched with the water outlet is arranged at the lower end of the bottom of the floater. An appropriate gap is opened for water drainage operation through the floater according to the water volume under the pressure of water and the effect of the balance spring, water in a centrifugal barrel is automatically and continuously drained under the condition of non-stop operation, the airtightness of a centrifugal field is guaranteed, and separation of pollutants and oil liquid in the centrifugal field is not affected; and the displacement can be automatically determined according to the separated water volume, and water is drained in time.

Description

technical field [0001] The invention relates to the field of oil purification, in particular to a fully automatic drainage type centrifugal oil purification device. Background technique [0002] Whether it is the lubricating oil of the lubrication system of the thin oil station, the turbine oil or the hydraulic oil in each hydraulic system, if the oil is mixed with water and mechanical impurities, it will cause serious harm to the normal operation of the mechanical equipment. The failure of lubrication and hydraulic system caused by the pollution of oil and hydraulic oil accounts for more than 65% of all failures of thin oil lubrication and hydraulic system. Therefore, it is necessary to remove pollutants (solid particles, water, gas, etc.) in the oil. ) to ensure the normal working of mechanical equipment. The traditional oil purification methods mainly rely on platen type oil filter, filter type oil filter, vacuum plus filter type oil filter, coalescing type oil filter, e...

AI Technical Summary

Problems solved by technology

[0004] 1. It needs to be shut down and operated manually. In the actual operation process, the oil purification equipment will flow the separated impurities and water into the dirt box, and then manually open the valve at the bottom of the dirt box according to the size of the impurities and water to discharge the impurities and water. , this process needs to be shut down, which seriously affects the working efficiency of the oil purification equipment

[0005] 2. If the valve of the dirt receiving box in the oil purification equipment is changed to a solenoid valve, and the switch of the solenoid valve is controlled by the control device at regular intervals or according to the change of the liquid level in the dirt receiving box to realize automatic intermittent drainage, although this process There is no need to shut down the operation, but when the water content in the oil is large, the drainage efficiency of the oil purification equipment cannot be guaranteed, and it cannot meet the needs of actual production
