Anti-fire extinguishing multi-purpose pump product introduction

Anti-fire extinguishing multi-purpose pump product introduction

Supply resistance of multi-purpose pumps, anti-fire resistance of multi-purpose pump parameters, anti-fire resistance of multi-pump pricing, where there is good quality anti-fire resistance of multi-purpose pump

North and South, scramble

use:

The multi-purpose pump for preventing fire-fighting and hindering is mainly used for spraying a retarder solution in a coal mine to prevent spontaneous combustion of coal. It is suitable for fire prevention of floating coal spray inhibitor in the goaf of coal mining face, fire prevention of barrier liquid for high cap top pipe pressure injection, fire prevention of buried pipe injection inhibitor solution in the goaf of combustible coal seams, etc.
advantage:

It is improved on the basis of the original model WJ-24-2, not only the pump body is small, light weight, simple operation, high work efficiency, explosion-proof motor.

working principle

1. The anti-fighting and anti-fighting multi-purpose pump is a 3KW anti-riot motor V-belt driven liquid pump. The driven wheel works at 700~800r/min. When the crankshaft rotates one revolution, the three pumps in the three barrels Under the action of the water and outlet valve assembly, water absorption and drainage are performed three times, so that the water with a certain pressure fills the air chamber seat. Due to the continuous operation of the motor, the crankshaft drives the connecting rod to continuously push the slider member to make a reciprocating linear motion, so that the liquid The pump works continuously.
2. The air chamber is used to regulate the flow rate and pressure of the liquid pump. The inhibitor solution is in a tumbling state and enters the air chamber. The air in the air chamber gradually dissolves in the liquid and slowly decreases, usually after 3~. For 4 hours of continuous operation, the air chamber will be entirely liquid, affecting the stability of the pressure and the service life of the liquid pump.
3. The pressure gauge is a straight pipe type. Its advantages are anti-vibration, fatigue resistance, and not easy to damage. The disadvantage is that the scale is not fine.
4. The pressure regulating valve is used to regulate the working pressure. The pressure adjustment handle pulls the foot in the clockwise direction is the pressure relief, and the counterclockwise pulling the foot is the pressure.
