Self-cleaning circulating oil tank

Abstract

The invention discloses a self-cleaning circulating oil tank which comprises a cylindrical tank body, the cylindrical tank body is provided with an oil inlet (close to the upper end part of the tank body) and an oil outlet (close to the lower end part of the tank body), the oil inlet direction of the oil inlet extends along the tangential direction of the inner wall of the cylindrical tank body, and the end face of the lower part of the cylindrical tank body is of a reversed conical structure. According to the invention, the oil inlet of the oil tank extends along the tangential direction, and as the bottom of the oil tank is of a reversed conical structure, fed lubricating oil is in a rotational flow state; because the density of impurities is higher than the density of the lubricating oil, the impurities can be fed into the conical bottom and accumulated in the process of rotational flow, therefore, the lubricating oil in the space of the upper part of the conical bottom of the oil tank contains less impurities, thereby achieving the purpose of automatically removing impurities in the lubricating oil, and ensuring the quality of the lubricating oil, so that the normal operation of each friction pair of power equipment can be ensured; meanwhile, the jamming frequency of three-level filtering system such as a filtering device and a filter screen and the like can be reduced, and the problems that the pressure of an outlet of a circulating pump is excess and the oil supply of the power equipment is not enough can be avoided, thereby avoiding accident of the equipment, and reducing the maintenance cost.

Description

technical field [0001] The invention relates to an auxiliary equipment of a lubricating oil distribution station, in particular to a forced lubricating circulating oil tank. Background technique [0002] The lubricating oil station is an indispensable auxiliary equipment system for large-scale power machinery; the lubricating oil of large-scale power equipment generally adopts forced circulation lubrication. The lubricating oil station generally includes a fuel tank, a circulating pump and a filter; the circulating pump pumps the lubricating oil in the fuel tank to the lubricating part through the filter to achieve lubrication, and the lubricated lubricating oil returns to the fuel tank to form a cycle. It can lubricate the friction pair well, and take away heat and impurities at the same time, which is beneficial to the long-term operation of the friction pair. [0003] Since the lubricating oil for circulating lubrication needs to be used for a long time, the internal imp...

AI Technical Summary

Problems solved by technology

[0003] Since the lubricating oil for circulating lubrication needs to be used for a long time, the internal impurities will accumulate more and more. Although it passes through a three-stage filtration system such as filters and screens, it is easy to cause the lubricating oil to deteriorate or the impurities to enter the friction pair again, resulting in The equipment running state becomes worse, and the service life of lubricating oil becomes shorter

At this time, only the lubricating oil has to be replaced, which causes great waste; at the same time, due to the large amount of impurities, it will cause blockage of the three-stage filter system such as filters and filter screens, overpressure at the outlet of the circulating pump, and insufficient oil supply for power equipment, resulting in equipment breakdown. Accidents, increased repair costs
