Self-balancing multi-stage pump is bound to rise to the future of the pump industry

Self-balancing multi-stage pump - high-efficiency energy-saving self-balancing multi-stage centrifugal pump is a new type of product developed by the pump industry. Now many companies are producing and promoting this product, because this self-balancing multi-stage pump is bound to The development trend of future water pumps will arise.

The self-balancing multi-stage pump is improved on the basis of the original traditional multi-stage pump. The obvious uniqueness of this multi-stage pump is:

1. High-efficiency - The ability to continuously operate for 8,000 hours without failure, which increases the efficiency of the work, while also reducing maintenance costs;

2. Power Saving—Compared to the conventional multi-stage pump, this self-balancing multi-stage pump saves up to 3% to 14%, which greatly saves the user's cost.

3, no balance device - This is an obvious characteristic of self-balancing compared to traditional multi-stage pump. This product is due to the non-equilibrium device, that is, the disc friction loss without balance disc and no balance of the return loss, so the pump efficiency is 5-14% higher than the same class of multi-stage pump, and completely solve the balance device due to the failure of the balance plate and balance The wear of the disk base or the failure of the rotor to kill it greatly prolongs the life of the pump.

Self-balancing multi-stage pump compared to the traditional multi-stage pump technology advanced 1, advanced combination of modular design, extensive use of long-term operation of the test of the local components, parts and components have a high degree of interchangeability.

High-strength, high-quality materials, as well as a wide selection of inlet and outlet flanges and splices, improve the pump's high allowable load, and the high-strength, high-quality pump casing structure has a close service life that is five times that of conventional castings. The impeller and guide vane in the over-flow area are precision cast, and the smoothness and smoothness of the impeller increase by more than 2% over the ordinary castings. Can meet the specific requirements of the system under special circumstances of the user at any time.

2. The rapid assembly and disassembly design allows the water pump to replace the seal and bearing components without disassembling the pump body and the inlet and outlet lines, ensuring less overhaul and inspection time.

3, high efficiency, high reliability, low cost combination. Through the optimal combination of impeller and guide vane, reasonable fit clearance and wide axial throttling design, ZPD high-pressure multi-stage centrifugal pump can still maintain its high stability and extremely high operation after long-term operation. effectiveness.

4, good cavitation performance. With excellent impeller hydraulic model or special double-suction impeller structure, users do not need to configure the front pump or increase the height of the inlet tank.

5. Symmetrically arrange the rotor components of the impeller, where the impeller is divided into two ends at high and low pressure regions, the axial forces cancel each other out and balance, the instantaneous axial force of the pump under working conditions and the residual shaft due to machining error and spiral seal The directional force is borne by the thrust bearing mechanism of the bearing component. This type of pump eliminates the axial force balance mechanism such as the balance plate or the balance drum. It completely avoids the sudden loss of the rotor caused by the failure of the balance plate or the balance drum. , Parts damage, broken shafts, and even the burning of motor accidents.

6. Safe pump body seal design. According to different pressures and structures, the pump body adopts a hard seal or O-ring seal that faces the metal surface.

According to user requirements, the center tap and minimum flow system can be increased.

The pump can be replaced and sealed without removing the inlet and outlet lines.

The unique performance and advanced technology of self-balancing multi-stage pumps are constantly meeting the needs of users. The current development situation and the needs of users have opened up high-efficiency, energy-saving and environmental protection. It is bound to be the development of the future water pump, and the self-balancing multi-stage pump eliminates the balance disk device, which solves various annoyances caused by the balance disk wear and reduces maintenance. Costs, etc. From all aspects, the self-balancing multi-stage pump is bound to arouse the development trend of future water pump and become the main product of multi-stage pump!
