Abstract

A control gate circuit of a pumping unit including power, A phase control drive chip and a lock brake, A phase control driving chip is respectively connected with a second uncontrolled half-wave rectifying module, precharge circuit, An isolation optocoupler is respectively connected with an isolation power supply module and a controllable full-wave rectifying module, wherein the isolation power supply module is connected with a first uncontrolled half-wave rectifying module, the controllable full-wave rectifying module is connected with a lock brake, and the controllable full-wave rectifying module, the first uncontrolled half-wave rectifying module and the second uncontrolled half-wave rectifying module are connected with the power supply. The utility model solves the problem that the rolling occurs due to the load difference when the electric motor of the pumping unit is stopped in the prior art.

Description

technical field [0001] The invention belongs to the technical field of pumping unit control, and relates to a control gate circuit of a pumping unit. Background technique [0002] With its advantages of long stroke and low stroke times, the vertical direct drive pumping unit is gradually replacing the beam pump and becoming the main equipment of modern oil pumping equipment. Vertical direct drive pumping units generally use belts and wire ropes as the transmission medium for the connection between the wellhead side and the counterweight side. When the motor of the pumping unit is stopped, the vehicle will slide due to the existence of load difference, so a brake device must be added to keep the motor rotor in a static state. Contents of the invention [0003] The purpose of the present invention is to provide a control gate circuit for pumping units, which solves the problem in the prior art that the pumping unit will slip due to the existence of load difference when the ...
