performance parameter 

The pneumatic diaphragm pump is powered by compressed air and drives two flexible diaphragms in the chamber to deliver fluid. It has no gear structure and does not rotate when working. It allows the delivery of fluid containing particles of a certain size. With its unique explosion-proof performance, it is particularly suitable for the high gas environment in the coal industry, especially the drainage and sewage discharge operations at the heading face. Ingersoll Rand ARO pneumatic diaphragm pump has passed the China Coal Mine Safety Certification.

Provide products that can be used in hazardous environments. The classic PitBoss series mining pump adopts a special spark discharge alloy shell. These products have passed the comprehensive certification and conform to the ATEX EX I Ⅱ 2GDX grade. They are specially designed for such a special explosive environment in the coal industry, and are also suitable for production or processing workshops with dangerous gases, so as to build a solid safety line for your production.

ARO - Intelligent Automatic Drainage System

Ingersoll Rand ARO intelligent automatic drainage system makes use of the good pneumatic liquid level detection principle in the industry, and can easily control the liquid level to the required level by using only two air pipes together with ARO mining pump

Within the scope of, avoid empty beating of diaphragm pump, significantly reduce the underground inspection time of miners, and effectively help customers to save gas consumption and reduce costs.

At present, customers who have used Ingersoll Rand ARO intelligent automatic drainage system:

Shenhua Shendong Coal Group Shenhua Ningxia Coal Industry Group Inner Mongolia Dayan Mining Group

Datun Coal Power Group Shanxi Lu'an Mining Group Shanxi Xishan Coal Power Group

Classic Applications

■ Automatic control of the liquid level in the sump of various mine shafts

reliable

*英格索兰智能自动排水系统不含矿用泵

Implementation function

■ When the liquid level of the water sump rises and exceeds the high liquid level detection nozzle, start the diaphragm pump.

■ When the liquid level of the water sump decreases and approaches the low liquid level detection nozzle, close the diaphragm pump.

Main components

Pneumatic liquid level sensor

■ Judge the state of liquid level by sensing the tiny air pressure in the air pipe connected with the detection port.

■ High sensitivity without repeated adjustment. Pneumatic control valve

■ Low starting pressure, suitable for downhole low air pressure conditions.

■ High action life, strong tolerance, and adapt to the requirements of harsh downhole conditions and frequent startup and shutdown. Detection of gas pipe

■ Just fix the orifices of the "high" and "low" detection gas pipes near the required liquid level, and the water level range can be easily set.

■ The installation and disassembly are flexible, and the required installation space is very small.
