Application of Pneumatic Diaphragm Pump in Coal Mine Drainage System
China's complex geological conditions, the frequent occurrence of geological disasters in mining a serious threat to the safety of coal mine production, mine water is one of the major disasters that threaten the safety of miners, in order to ensure the safety of miners and the normal operation of the mine, the application of coal mine drainage system has become the key, "mining pneumatic diaphragm pump", a compressed air for the power of mine drainage equipment.
Due to the characteristics of the working principle of the pneumatic diaphragm pump, the pneumatic diaphragm pump has the following characteristics:
(1) The pump will not overheat: compressed air is the driving force, and it is a process of expansion and heat absorption during exhaust. The temperature of the pneumatic pump is reduced when it works, and no harmful gas is discharged.
(2) will not produce electric sparks: pneumatic diaphragm pump does not use electric power for power, and after grounding, it prevents electrostatic sparks.
(3) It can pass through the liquid containing particles: because the volumetric work and the inlet is a ball valve, it is not easy to be blocked.
(4) The shear force on the material is low: how to suck in and spit out during work, so the agitation of the material is small, which is suitable for the transportation of unstable substances.
(5) The flow rate can be adjusted, and a throttle valve can be installed at the material outlet to adjust the flow rate.
(6) has the function of self-absorption.
(7) It can be flown without danger.
(8) can dive work.
(9) can transport a wide range of fluids, from low viscosity to high viscosity, from corrosive to viscous.
(10) No complicated control system, no cables, fuses, etc.
(11) small size, light weight, easy to move.
(12) No lubrication is required, so maintenance is simple and will not pollute the working environment due to dripping.
(13) The pump can always maintain efficiency and will not be reduced due to wear.
(14) energy utilization, when the outlet is closed, the pump automatically stops, there is no equipment movement, wear, overload, heat.
(15) There is no dynamic seal, easy maintenance to avoid leakage, and no dead spots during work.
