Balance hole is not too large, mainly affect the efficiency of the pump, the following describes the pump axial thrust balance of several methods :
1. Opening balance hole
2. The balance tube
3. Using balanced blade
4. Double suction impeller
Because of its variable delivery, self absorption capacity, can be reversed, can transport the liquid containing solid particles and so on, in the sewage treatment plant, widely used in the transport of water, wet sludge and flocculant liquid. Screw pump
The slurry pump will appear idle phenomenon, usually because the internal pump malfunction phenomenon. Therefore, we want to avoid the slurry pump slurry pump idling phenomenon leads to excessive wear phenomenon, we need to avoid this idle phenomenon, tim
Axial flow pump is a high speed pump, the impeller flow channel is wider, the cavitation is not serious, the performance of the pump is almost no effect. Only when the cavitation development to a serious stage, will affect the working performance of the p
The axial flow pump in the sewage treatment plant is used as a reflux sludge pump, and the two settling sludge pump is returned to the front end of the biochemical pool and mixed with the water inlet. Return sludge pump is generally equipped with frequenc

Pump cavitation, erosion and damage to the joint effect is always an important problem in the water pump operation, maintenance and management, the traditional materials and surface protection technology can not meet the requirements of anti cavitation an
Deep well pump efficiency refers to the ratio of the actual pumping well liquid production and deep well pump displacement theory. Actual production in order to separate the amount of oil as the basis, the theoretical displacement of the deep well pump is
High temperature hot water pump can be 24 hours a day, water, high water pressure, constant temperature to provide the family with different hot water needs, but also consume the least amount of energy to complete the above requirements of the water heate
The taper of the shaft neck and the ellipse degree is not larger than the diameter of the 1/2000. But shall not exceed the maximum 0.05mm, and the surface shall not have scars, exceed the allowable value of axial bending straightening by mechanical or hea
Pump in the open (open loop) is also known as single stage double suction centrifugal pump, the main features of the medium flow, working principle of pump running head: the impeller installed in the pump shell, and fastened on the pump shaft, the shaft d
1.If there is any small sewage pump failure remember not to let it work. If the pump shaft of the filler to be added in a timely manner, if you continue to use the pump will leak. The direct effect of this is that the energy consumption of the motor can b
1.Must meet the requirements of using the flow and head, which requires the pump operating time point (intersection curve and performance characteristics of the pump device) to keep running at high efficiency range, so that power is both easy to damaged p
Self priming centrifugal pump for the first time before starting to use, only need to pump the pump casing into the 2/3 of water, and then start the pump automatically after the water can be sucked up.
Our production of large double suction spiral case in the open pump, flow 4850M3/H, head 20M, matching power 250KW, the number of 8 sets. The pump shell is made of HT250 material disappear grinding casting, the impeller, ring 304 stainless steel shaft, ma
The common mechanical failure and failure of deep well pump have the oil valve cover fracture, pump barrel fault, oil inlet valve cover failure, excessive deformation of the parts of the deep well pump, the failure of the deep well pump.
The tubular pump deep well pump is directly connected to the bottom of the oil pipe column, which is composed of a pump barrel assembly, a plunger assembly, a fixed valve assembly, a fixed valve fixing device and a fixing valve salvage device.
The foundation excavation in the construction of the city, and auxiliary buried underground pipes, underground water is the first problem to be solved, and the key to solve the problem is to use the pump can easily be extracted from the ground water and
Submersible pump is a vane pump, depending on the rotation of the impeller in the spinning process, due to the interaction of blade and liquid, blade mechanical energy to the liquid, the liquid pressure can increase, to achieve the purpose of conveying li

1.Remove the water pump from the engine.
2.The front axle nut submersible pump, unscrew and remove the water pump cover, impeller and seal pressure.
3.Check if the seal, the seal is bakelite, wear is not too serious, can be put in a glass or dry clo
The problem of slurry pump wear is mainly manifested in the:
1.The impact of work efficiency. Due to the gap between the impeller and the pump body mutually wear, the pump volume efficiency decreases gradually with the increase of flow surface wear and
