self-balancing multistage pump With its high efficiency, low vibration, long life and strong adaptability and other advantages, it has become the priority of the pump device in many industries. The self-balancing multistage pump is an efficient and reliable pump device, which has become the ideal choice for the majority of demanders, with the following significant advantages.

1. Low noise

The self-balancing multistage pump has less vibration and noise. Due to the characteristics of multi-stage design, the vibration generated by each stage will cancel each other, thus reducing the overall vibration of the pump. At the same time, the self-balancing multi-stage pump has a compact structure and stable operation, which reduces the generation of noise and makes the working environment quieter.

2. Longer life

The self-balancing multistage pump has a long service life. It adopts advanced design and manufacturing technology, uses wear-resistant and corrosion-resistant materials, and can operate normally under harsh working conditions. At the same time, the self-balancing multi-stage pump has simple structure, few parts, convenient maintenance, reduces the probability of failure, and prolongs the service life of the equipment.

3. Low maintenance rate

The use of precision casting reduces the number of vulnerable parts and maintenance disassembly and assembly, prolongs the life of the product, avoids a series of problems caused by excessive disassembly and assembly, and reduces the maintenance cost.

4. Strong applicability

Self-balancing multistage pumps have high adaptability. It can be adjusted and combined according to different working conditions to meet the working conditions of different flow and head. This flexibility makes self-balancing multistage pumps widely used in industry, agriculture, construction and other fields to meet various needs.

Advanced combination of modular design, after a large number of use, long-term operation of the test of local components, components with a high degree of interchangeability. Cancel the small gap balance disc, than the traditional multi-stage pump structure to adapt to the media properties more harsh occasions pump first stage impeller adopts double suction structure, so that the pump has good anti cavitation performance, the whole machine runs smoothly, low noise, long service life.

5. Easy maintenance

The whole product adopts three-dimensional design and numerical control processing of rotor parts, which strictly ensures the processing size and processing accuracy of each part. Positioning can be completed by ordinary technicians according to the assembly sequence and requirements of the assembly drawing. It completely avoids that the old multi-stage pump must have personnel to adjust the positioning axial jump size, which brings great convenience to users.

6. High stability

Through the matching of symmetrical impeller and guide vane, as well as reasonable matching clearance and wide axial throttle design, the pump can maintain general stability and high operating efficiency after long-term operation.

7. Good cavitation performance

Optimized hydraulic and structural design, precision casting, reliable wear-resistant materials, some models of pump first-stage impeller adopts double-suction structure, so that the pump has good anti-cavitation performance, smooth operation, low noise and long service life.

8. Strong mechanical sealing performance

When the pump starts and stops, the rotor parts have no axial movement, and there is no axial pulsation when working, which overcomes the problem of poor reliability of the machine seal that has been plagued by multi-stage pumps.

9. High efficiency and energy saving

Self-balancing multistage pumps have high efficiency. This is because it uses a multi-level design, each level has a certain lift. Through the reasonable stage configuration, the total head of the pump can meet the requirements, and in the process of each stage, the pressure change is small, thus reducing the energy loss and improving the efficiency of the pump.

Adopt advanced hydraulic model and independently develop high-efficiency and energy-saving products. As the pump rotor does not have the wear and axial pulsation of the balance disc, the neutral orientation of the impeller and the guide vane is always in the state, which will not cause obvious efficiency decrease with the wear of the balance disc and the forward movement of the rotor components like the common multi-stage pump structure. In addition, there is no leakage of balance water, which reduces volume loss, improves the overall pump operation efficiency and reduces shaft power, the average efficiency is 5%-8% higher than that of ordinary multi-stage pumps.

10. New Structure

With the symmetrical arrangement of the impeller rotor components, the axial forces generated by the symmetrical impellers at all levels cancel each other out, and the automatic balance of the huge axial thrust in the pump cavity can be realized without using the balance disc structure, which breaks through the traditional structure of the multi-stage pump.

11. New Technology

Unique throttling, decompression device, odd-level balance device, but also play an auxiliary support role.

12. High reliability

The symmetrical arrangement of the impeller makes the axial thrust generated during operation basically self-balanced, so that there is no need for a balance disc device with small gaps, high pressure drop, easy to wash, easy to wear, and easy to malfunction, so that the axial force load affects the pump The adverse effects of wear and system interference are reduced to small. The residual axial force is borne by the thrust bearing, so that the pump shaft is always in a state of tension, the force state of the shaft is uniform, and the stress peak is greatly reduced compared with the prototype structure, thereby improving the rigidity and critical speed of the pump rotor, so that the pump rotor operation The stability and reliability are significantly improved.
