Abstract

The invention discloses a metering pump with an entire solid eccentric wheel travel adjustment mechanism. The metering pump comprises an amount adjustment lead screw, a moving shaft, a hollow shaft, a connection rod, the entire eccentric wheel, a worm gear, a worm and a slide rod, wherein one end of the amount adjustment lead screw is connected with the moving shaft in a mode of coaxial relative motion, the moving shaft is sleeved in the hollow shaft, a chute is formed in the moving shaft, a slide block is arranged in the chute, the entire eccentric wheel is sleeved on the hollow shaft and fixed with the connection rod, the connection rod is connected with the slide rod, and the worm wheel is in cup joint to the hollow shaft and is meshed with the worm. The metering pump is large in bearing capacity, high in metering precision and long in service life.

Description

technical field [0001] The invention relates to a stroke adjustment mechanism, in particular to a metering pump with an integral eccentric wheel stroke adjustment mechanism. Background technique [0002] Metering pump is a reciprocating pump capable of metering and transporting liquid. In addition to the characteristics of reciprocating pumps, it also has the characteristics of stepless flow adjustment. The metering pump is composed of a motor, a transmission box, a cylinder block and other parts. The transmission box includes a connecting rod cam mechanism, a stroke adjustment mechanism and a deceleration mechanism, and the stroke adjustment mechanism is an important part of the metering pump to realize stepless flow adjustment. [0003] The patent document with the document number CN 1796786A describes a stroke adjustment mechanism of a metering pump, including a worm wheel, a worm, an adjustment rod and an eccentric wheel. The eccentric wheel is connected to a connecting ...
