Abstract

The invention provides a non-contact pneumatic measuring plunger pump, and aims at solving the problem that a traditional measuring plunger pump is low in measuring precision. The non-contact pneumatic measuring plunger pump comprises a plunger pump body and an air motor, and the air motor drives the plunger pump body; the air motor comprises a cylinder, a motor piston rod assembly and a screw rod nut assembly. The motor piston assembly comprises a motor piston rod and a piston which is arranged in the cylinder. The screw rod nut assembly comprises a screw rod and a nut connected to the screw rod in a sleeving mode. The motor piston rod is provided with a center hole in the axial direction, one end of the screw rod is connected into the center hole of the motor piston rod in a sliding mode, and the other end of the screw rod is rotationally connected to the cylinder; the nut and the motor piston rod assembly are fixed together. The pneumatic measuring plunger pump body further comprises a rotary encoder. The rotary encoder obtains a motor piston rod stroke by measuring the number of rotations of the screw rod; by means of the motor piston rod stroke of the air motor, the volume of fluid conveyed by the plunger pump body can be deduced.

Description

technical field [0001] The invention relates to a non-contact pneumatic metering plunger pump. Background technique [0002] In the field of fluid transfer, metering problems are often encountered. Traditional high / low viscosity fluid delivery and metering is done in the form of a pump combination flow meter. The traditional metering method is mostly contact metering, and its metering accuracy is affected by particles, temperature, viscosity, etc. in the metering medium. The measurement accuracy is low, and the ability to identify the minimum flow rate is low. Contents of the invention [0003] The invention provides a non-contact pneumatic metering plunger pump, which aims to solve the problems of low metering accuracy and limited application range of traditional pump combined flowmeters. In addition, the existing non-contact metering flow meters are expensive and complicated to operate. [0004] In order to solve the above technical problems, the present invention is...
