Problems solved by technology

Small hole group noise reduction is widely used in the control of compressed air discharge. The smaller the aperture of the small hole group, the better the noise reduction effect, but it will cause a large back pressure, which will affect the effective use of air pressure, and will also cause ice to block the discharge. The air hole thus affects the speed of the air motor, and even cannot work
This type of muffler cannot meet the requirements of relevant domestic and foreign standards in harsh sites such as mines and underground mines.

Abstract

The invention relates to a pneumatic diving pump which comprises a shell. The shell is provided with a water inlet, a water outlet, an air inlet and an air outlet, wherein the water outlet is provided with a first drain pipe, and the air outlet is provided with a vent pipe which communicates the air outlet and the first drain pipe so as to discharge compressed air drained from the air outlet and sewage drained from the water outlet along the first drain pipe. The invention basically realizes no power loss and no noise, does not generate an icing block phenomenon, can improve the pump lift at a full flow rate, has simple structure, smart conception, remarkable energy-saving effect and low manufacture cost and greatly improves the practicability of the pneumatic diving pump.

Description

technical field [0001] The invention relates to a pneumatic submersible pump, in particular to a drainage device for the pneumatic submersible pump. Background technique [0002] Pneumatic submersible pumps generally have three types: turbine impact turbine type, volume vane type, and volume gear type. Pneumatic (pneumatic) motors are used as the coaxial prime mover of the pump, which has explosion-proof performance and is not subject to vibration, high temperature, electromagnetic radiation, etc. It can work normally under flammable, explosive, high temperature, vibration, humidity, dust and other conditions. It is very suitable for harsh working environments, especially high gas mines, absolutely safe and reliable. However, the pneumatic submersible pumps currently available on the market all have the defect of high noise, and the general noise is 85 decibels to 118 decibels, which seriously affects the physical and mental health of construction workers on site. [0003] ...
