Features of high lift submersible pump

Tell us about the characteristics of high lift submersible pump

How to adjust and control the water flow of high-lift submersible pump?

ForHigh-lift submersible pumpThe use of, we mainly to drainage, so for the control of water and water flow, I believe many people do not know what to do, next, we will explain the submersible pump water flow control of various adjustment methods.

1. Variable speed adjustment, changing the speed of the submersible pump can change the performance of the pump, thereby changing the working point of the pump. This method is called variable speed adjustment.

2. Variable diameter adjustment. After rotating the impeller, the performance of the pump will change according to a certain rule, thereby changing the working point of the pump. We call the method of rotating the impeller to change the working point of the pump as variable diameter adjustment.

3. Variable angle adjustment, changing the installation angle of the blades can change the performance of the pump, so as to achieve the purpose of changing the working point of the submersible pump. This way of changing the working point is called variable angle adjustment of the pump.

4. Throttling adjustment. For the water pump device equipped with a gate valve in the outlet pipeline, when the gate valve is closed, the local resistance in the pipeline increases, which steepens the characteristic curve of the pipeline, and its working point moves to the upper left along the Q-H curve of the water pump. The smaller the gate valve is closed, the greater the increased resistance and the smaller the flow rate. This method of changing the working point of the pump by lowering the gate valve is called throttling or variable valve.

The power part of the stainless steel submersible pump adopts the oil-immersed type produced by the current international advanced technology. The submersible stainless steel submersible motor and submersible motor have zero pollution to water quality. They are excellent pumps in deep wells at home and abroad. They have high-quality stainless steel shell, inverted steel shell, shaft core, coupling and new floating impeller. They have no axial force on the motor during operation. The product has the advantages of high head, small pump diameter and small flow, the appearance is smooth, beautiful, high-quality, wear-resistant, long life, high pump efficiency, power saving, and convenient maintenance.

　High-lift submersible pumpIt is to lift the water of single-stage or multi-stage charge pump on the wet surface of the three-phase asynchronous electric submersible pump, and is committed to the development of agricultural irrigation and sprinkler irrigation, industrial and civil building drainage systems.

Stainless steel high lift submersible pump features:

1. The stainless steel submersible pump is composed of two main submersible three-phase asynchronous motors and pumps. The motor is directly connected to the upper pump body. The upper end of the motor shaft is equipped with a reliable shaft seal device, which can effectively prevent the coolant and pumping medium in the motor Exchange to ensure the long-term safe and reliable operation of the stainless steel submersible pump.

2. It is a stainless steel submersible pump suction multi-stage vertical centrifuge unit; the submersible motor is wet with water, and the straight well uses a submersible induction motor. The motor is directly connected to the stainless steel submersible pump through a cylindrical coupling.

3. The motor winding uses polyethylene nylon sheathed water electromagnetic wire, and fills the motor cavity with clean water.

4. Lubricate the bearing with water motor guide bearing. The lower part of the motor is equipped with thrust bearing that can bear the upper and lower axial force of the pump. The thrust bearing of high-lift pump adopts nickel-copper sector block.

5. The stainless steel submersible pump motor has an additional intermediate axial force carrier, and the head can be increased to 900 meters.

okay, thank you all for watching, let's see you next time.
