Abstract
The invention relates to the technical field of metering pump equipment, in particular to a symmetric metering pump transmission mechanism with a sliding block frame connecting rod and a metering pump. The symmetric metering pump transmission mechanism comprises a transmission component, a motor, a pump body and a plunger, and further comprises a sliding block frame connecting rod component, a connecting component and two guide components. The sliding block frame connecting rod component comprises a left sliding block frame, sliding blocks, a right sliding block frame and a sliding block connecting rod. The left sliding block frame and the right sliding block frame are arranged symmetrically through the sliding block connecting rod. The sliding blocks are slidably mounted in the left sliding block frame and the right sliding block frame correspondingly. The transmission component is connected with the sliding block frame connecting rod component through the connecting component. The two guide components are oppositely mounted on the two sides of the sliding block frame connecting rod component and do reciprocating linear motion with the sliding block frame connecting rod component.The symmetric metering pump transmission mechanism has the beneficial effects that the left sliding block frame and the right sliding block frame are symmetrically arranged; the sliding blocks are insliding fit in the left sliding block frame and the right sliding block frame; reciprocating motion paths of the left and right guide components are located on the same straight line; and the slidingblock frame connecting rod component has high load-bearing capacity and operation is more stable.
Description
technical field [0001] The invention relates to the technical field of metering pump equipment, in particular to a metering pump transmission mechanism of an opposed slider frame connecting rod and a metering pump. Background technique [0002] The metering pump is composed of two parts, the power end and the liquid end. The power end drives the plunger to reciprocate through the crank linkage mechanism, and the stroke flow is changed through the N-shaped shaft adjustment mechanism; the power end transmission mechanism consists of a motor, a motor bracket, and a transmission box (including a worm gear, a crank linkage mechanism, Stroke adjustment mechanism), pump head bracket, etc. [0003] In the field of metering pump delivery, in order to achieve greater flow and higher pressure delivery, opposed double-head metering pumps are usually used. The reciprocating motion routes of the large end of the connecting rod and the small end of the connecting rod of the existing oppo...
