Problems solved by technology

[0002] The piston pump is a reciprocating metering pump. Its working principle determines that after completing a working stroke, it needs to move in reverse to absorb material. There is a working vacuum period and it cannot work continuously.
[0003] Most of the piston pumps currently on the market work in one direction and cannot work continuously, which is a waste of time
A small number of two-way piston pumps can also work continuously, but there is a flow interruption phenomenon during continuous work, and it is impossible to achieve uniform discharge, and the discharge speed control is not accurate

Abstract

The invention is suitable for the field of piston pumps, and provides a two-way piston pump and a control method thereof. The piston pump comprises a control system, a first one-way metering pump, a second one-way metering pump, a first driving mechanism and a second driving mechanism; the control system controls operation or standing of the first and second driving mechanisms; the first and second one-way metering pumps are respectively connected with the first and second driving mechanisms; each one-way metering pump has a hollow cavity, a sucking port and a discharge port; the cavity is communicated with the sucking port and the discharge port; a pneumatic ball valve is mounted in the sucking port; a one-way valve is mounted in the discharge port; each driving mechanism includes a piston rod capable of extending; the end parts of the piston rods are inserted in the cavities of the one-way metering pumps, and perform a reciprocating motion in the cavities; and the control system controls the first and second driving mechanisms to drive reverse movement of the two piston rods. The piston pump has two sets of one-way piston metering pumps; one set is for feeding, and the other set is for discharging; and the two sets are alternately operated to realize continuous discharge of the piston pump.

Description

technical field [0001] The invention belongs to the field of piston pumps, in particular to a bidirectional piston pump and a control method thereof. Background technique [0002] The piston pump is a reciprocating metering pump. Its working principle determines that after completing a working stroke, it needs to move in reverse to absorb material. There is a working vacuum period and it cannot work continuously. [0003] Most of the piston pumps currently on the market work in one direction and cannot work continuously, which is a waste of time. A small number of two-way piston pumps can also work continuously, but there is a flow interruption phenomenon during continuous work, and it is impossible to achieve uniform discharge, and the discharge speed control is not accurate. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a two-way piston pump and its control method, aiming at improving the working efficiency ...
