When mining, the groundwater in the mine needs pumping equipment to be discharged out in a timely manner. The well point drainage method is a construction method that allows continuous pumping of groundwater. The well point construction method is a construction method in which a series of well points are buried below the groundwater surface at 1 to 2m intervals and a self-priming pump or vacuum pump is used to compulsorily draw in groundwater. The water attracted from the suction pipe through the rotary joint gathered in the well point main pipe for drainage, the traditional well point drainage system, mostly using vacuum pumps, but the vacuum pump to meet the suction function, there are many drawbacks, the formation of vacuum is slow; working noise; in addition, the vacuum pump in the work, need to cooperate with the set of one or more vacuum tank, complicated system and a large space occupation is very unsuitable for mining such non-stationary site.
Ace lobe pumps, as a strong self-priming, low-noise pumping equipment, are more often chosen for well point drainage systems, with the following specific advantages.
1、Strong self-priming ability
In terms of self-priming performance, thanks to the ingenious design principle (the medium is filled in a sealed space in the pump chamber and pumped away with the movement of that sealed space), the lobe pump can create a vacuum in a short time without the need to set up a vacuum tank or to inject liquid into the pump chamber at start-up time; self-priming heights of up to 9 m water column are possible.
2. Portable or mobile
In terms of portability, the lobe pump can be driven by a diesel engine, eliminating the need for a drive for outdoor work without power: Ace has also designed a semi-mobile well point drainage pump system, where the pump and drive system are connected and mounted together on an integral base with pulleys underneath and a lifting frame above to facilitate the transfer of the pump equipment to different locations.
3、Strong wear resistance
lobe pumps can handle abrasive slurries with up to 85% solids content and can replace centrifugal slurry pumps, hose pumps, diaphragm pumps etc. Compared to hose and diaphragm pumps, Ace lobe pumps have a large flow range, high pressure rating and guarantee a stable delivery without pulsation.
4、On-line maintenance, easy maintenance
Zhejiang Ace Pump Technology Co., Ltd. is a large comprehensive pump company integrating design, research and development, production and sales of lobe pumps, rotary lobe pumps and rubber lobe pumps. Its products are widely used in the fields of grease, petrochemical, clearing and sweeping tanks, underground and high speed railway sewage, breeding sewage, food waste disposal and so on. Over the years, the company has been focusing on the technical research, manufacturing and production of various types of pumps, and is committed to providing customers with applicable pump handling system solutions.
