MDSP first stage double suction mine self-balancing multistage pump, the first stage impeller adopts double suction design, can effectively reduce the pump cavitation, this type because there is no balance disc wear and axial pulsation, the neutrality of the impeller and guide vane is always in a state of alignment, not like the ordinary multistage pump structure, will be with the balance disc wear, rotor parts move forward and the efficiency of the problem; Without balanced water leakage and volume loss, the operation efficiency and service life of the pump are improved on the whole, and the efficiency is increased by 5-14% on average than that of ordinary multistage pumps.
Parameter range and model description:
Flow Q: 200-335m³/h;
Head H: 496-540m;
Model: MDS280-65X8P;
MDSP - first double suction mine self-balancing multistage pump;
280 -- design point flow 280m3/h;
65 -- single-stage design point lift is 65m;
8 - the stage of the pump.
Complete range:
Water pump, motor, base, coupling, protective cover, anchor bolt.
How it works:
MDSP first double-suction mine self-balancing multistage pump shaft rotates under the drive of the motor, and does work on the liquid to increase its energy, so that the required amount of liquid from the suction pool through the pump inlet section, impeller, positive guide vane, middle, horizontal outlet of the outlet section, transition pipe, secondary inlet section, anti-impeller, anti-guide vane, vertical outlet of the outlet section, Send the liquid out in a steady stream.
Performance structure advantages:
1. High efficiency and energy saving
Adopt advanced hydraulic model, independently develop energy-saving products; Because the pump rotor does not have the wear and axial pulsation of the balance disc, the neutrality of the impeller and guide vane is always in a stable state, and the efficiency of the multistage pump structure does not decrease significantly with the wear of the balance disc and the forward movement of the rotor components. Without the leakage of balanced water, the volume loss is reduced, the operating efficiency of the pump is improved on the whole, and the shaft power is reduced, and the efficiency is 5%-14% higher than that of the ordinary multistage pump.
2. New structure
With symmetrical impeller rotor components, the axial forces generated by each level of symmetrical impeller cancel each other, and the huge axial thrust in the pump cavity can be automatically balanced without using the balance plate structure, which breaks through the traditional structure of multi-stage pump.
3. New technology
Unique throttling, reducing device, odd-stage balancing device, can also play an auxiliary supporting role;
4. High reliability
The symmetrical arrangement of the impeller makes the axial thrust generated in the operation basically self-phase balance, so that there is no need for small clearance, high pressure drop, easy erosion, easy wear, easy failure of the balance disc device, so that the axial force load on the wear of the pump and the adverse impact on the system interference. The residual axial force is borne by the thrust bearing, so that the pump shaft is always in the tension state, the force state of the shaft is uniform, and the stress peak value is greatly reduced compared with the prototype structure, thus improving the rigidity and critical speed of the pump rotor, and significantly improving the smoothness and reliability of the pump rotor operation.
5, good cavitation performance, long service life
Optimized hydraulic and structural design, precision casting, reliable wear-resistant material, some types of pump first stage impeller adopts double suction structure, so that the pump has good anti-cavitation performance, smooth operation, low noise, long service life;
6, the machine seal strong reliability
When the pump starts and stops, the rotor parts do not move axially, and there is no axial pulsation during operation, which overcomes the problem of poor seal reliability that has been bothering the multistage pump.
7, widely used
The small gap balance plate is eliminated, and the multi-stage pump structure ADAPTS to the occasions where the medium properties are worse than the traditional ones.
8. Low maintenance cost
The use of precision casting, reduce the number of wearing parts and maintenance disassembly, extend product life, avoid a series of problems caused by too much disassembly, reduce maintenance costs;
9, easy maintenance
The product adopts three-dimensional design and CNC machining of rotor parts, which strictly ensures the processing size and precision of each part. The positioning is accurate, and the general technical personnel can complete the assembly according to the assembly order and requirements of the final assembly drawing; Completely avoid the old multistage pump must be professional to adjust the positioning of the axial jump size, bring great convenience to users.
