Multi-point oil injection pump

Abstract

The invention provides a multi-point oil injection pump which comprises a valve body provided with a valve element channel, a valve element partially contained in the valve element channel, an oil inlet connector communicating with the valve element channel, an adjustment plug blocking the free end of the valve element channel, a cylinder connected with the valve body, an air inlet connector communicating with the cylinder, a piston located in the cylinder and connected with the valve element in an abutting mode and a first spring connected between the piston and the valve body and arranged outside the valve element in a sleeving mode. The valve body is provided with an air exhaust hole communicating with the cylinder and provided with a plurality of valve body oil outlets sequentially distributed in the longitudinal extension direction of the valve body. The valve element is provided with a valve element inner cavity which communicates with a plurality of valve element oil outlets annularly distributed in the valve element inner cavity. The valve element is pushed through inflation to move so as to enable the valve element oil outlets to sequentially communicate with the valve body oil outlets located in different positions, so that the valve element oil outlets and the different valve body oil outlets form a plurality of oil supply passages, oil injection efficiency and stability are improved, and oil injection cost is reduced.

Description

technical field [0001] The invention relates to the technical field of oil injection devices, in particular to a multi-point oil injection pump. Background technique [0002] Bearings are common mechanical parts, used to determine the relative movement position of the rotating shaft and other parts, and mainly play a supporting or guiding role. Its main function is to support the mechanical rotating body to reduce the friction coefficient of the mechanical load during the transmission process of the equipment. Bearings are widely used in machine tools, motors, conveyors, generators, etc. The life of bearings is very important to the use of equipment, but bearings generally work in high-speed, high-temperature and heavy-load environments, and their life is greatly affected. [0003] Usually a piece of equipment needs to be installed with multiple bearings, such as the core equipment spray head used in the flue gas treatment system of a waste incineration power plant, and mu...

However, in the prior art, the oil in the oil-air lubrication device is poured into the oil-air mixing chamber at one time, so that the mixing of oil and gas is uneven, resulting in over-lubrication or insufficient lubrication during the process of oil-air lubrication device delivering oil and gas to the bearing.
