First of all: the traditional sense of mining submersible pumps. That is, the QJ series of water pumps. This kind of water pump 100 percent are faced with the problem of excessive axial force. Some manufacturers carry out a variety of technical protection. Strength and technology manufacturers have developed a high-pressure load-bearing balancer. This device can effectively alleviate the axial force generated by the pump operation. This is the first generation of mining submersible pumps. It is this kind of mining submersible pump customers need to pay attention when choosing. Try to find fully qualified manufacturers, because these manufacturers use strength and technology to test and verify. Those manufacturers without qualification can't make it. Even the qualification can not do, not to mention the various forms of test equipment and testing equipment, you say?
Next is a variety of models and descriptions of non-axial force mining submersible pumps, the type of mining submersible pumps are mostly changed from the horizontal centrifugal pumps, which is the second generation of mining submersible pumps, this type of submersible pumps are still unable to break through the traditional sense of the limitations of the axial force, which is no more than a reduction of some of the axial force. And in the transformation process, the technology is still not mature enough. The advantages of this type of pump are: the shape is thick and short, and the flow and head are large. Suitable for mining, but the stability and use of time can not be effectively guaranteed.
Finally, it is the new self-balancing mine submersible pump and double suction mine submersible pump. This is the third generation of new and safe mining submersible pumps. Self-balancing using a single inlet, positive and negative impeller design, positive axial force after the water feedback offset, the pump can achieve no axial force operation, safe and reliable. Colleague unit in addition to the bearing device and a variety of axial force constraints on parts, so that as far as possible to reduce the mining submersible pump wear parts, further improving the safety of the mining submersible pump coefficient. And this type of mine submersible pump, installation and maintenance is simple, through the performance is good, stable operation, can effectively ensure that the mine drainage needs. Double suction mining submersible pumps also use double impeller design, both ends of the water inlet, offset each other axial force and then out of the water. So the stability and safety of the same self-balancing mining submersible pumps. It is the choice of the majority of mining enterprises.
