Working principle

The core of the alcohol injection lever is the piston metering pump, which achieves fluid injection through the reciprocating motion of the piston metering pump. The piston metering pump is mainly composed of two parts: the motor and the piston pump. The motor drives the piston pump to move back and forth through the coupling. When the piston moves to the rear dead center, the pump chamber gradually forms a volumetric vacuum. Under the action of the atmosphere, the suction valve opens to suck in the liquid; When the piston moves forward to the dead center, the suction valve closes and the discharge valve opens, and the liquid is discharged from the pump, enabling the pump to achieve the purpose of suction and discharge, thereby achieving fluid filling.

Structure and Characteristics

The alcohol injection pry is mainly composed of a base, piston metering pump, storage tank, pressure gauge, observation hole, safety valve, liquid level gauge, related supporting valves and pipeline accessories, and electrical accessories.

There is a flow control handle on the piston metering pump, which can adjust the filling speed of the fluid; Storage tanks are used for storing and refilling liquids; After the system overpressure occurs, the safety valve automatically trips to protect downstream devices.
