Problems solved by technology

[0003] The first purpose of the present invention is to provide an explosion-proof servo volume control system to solve the problem that the existing volume control system cannot meet the high-precision and high-speed filling requirements at the same time. The volume control system uses an explosion-proof servo motor to control the ball valve. The linear opening and closing of the ball valve greatly improves the control accuracy and speed

Abstract

The invention relates to an anti-explosion servo weight control system and a weight control method thereof. The anti-explosion servo weight control system comprises a weight control main body and an anti-explosion execution unit; the weight control main body is connected with the anti-explosion execution unit through a connecting bracket, and the weight control main body and the anti-explosion execution unit are enabled to form an integral whole; a rotary shaft of the weight control main body is connected with a power output shaft of the anti-explosion execution unit through a connecting shaft, and a state of a weight control ball valve on the weight control main body is controlled by the anti-explosion execution unit; the anti-explosion execution unit comprises a servo motor, a planetaryreducer and an anti-explosion shell; and the servo motor and the planetary reducer are installed in the anti-explosion shell, the servo motor is connected with the planetary reducer, a rotating angleof the weight control ball valve on the weight control main body is controlled by the servo motor, and thus, linear open and close of the weight control ball valve are realized. The anti-explosion servo motor weight control ball valve is adopted in the weight control system to realize the linear open and close of the weight control ball valve, and control precision and speed are greatly improved.

Description

technical field [0001] The invention belongs to the field of volume control systems used in chemical explosion-proof liquid material filling machines, and in particular relates to an explosion-proof servo volume control system and a volume control method for accurately controlling the filling speed and precision of filling machines. Background technique [0002] At present, the volume control system adopted by the chemical explosion-proof liquid material filling machine is pneumatic ball valve control. This type of volume control can realize fast and slow filling, which can meet the general accuracy and speed requirements, but cannot meet the requirements of high precision and high speed. Filling needs. Moreover, since the pneumatic ball valve cannot realize the linear opening and closing of the ball valve, the speed will decrease when high precision is required, and the precision will decrease when the speed is increased. The existing electric ball valve drives the shaft...
