GDL Vertical multistage pump inlet and outlet

Vertical multi-stage pump inlet and outlet points up and down the structure, the user can be installed according to the actual situation will import and export direction from the vertical point of rotation 90 °, 180 °, 270 ° four positions. Pump shaft and motor shaft at the same level, the use of mechanical seal, bearings with low noise bearings, so the vertical multistage centrifugal pump running low noise, vibration is very small, greatly improving the use of the environment and improve the service life . It is characterized by small footprint, high head, easy installation and maintenance. For high-rise building water supply and drainage, fire pumps, factories, mines, oil and other units conveying temperature below 90 ℃ water or physical and chemical properties similar to water.
Vertical multistage centrifugal pump features:
1, the use of efficient standard motor, the motor shaft coupling directly connected with the pump shaft, flow chamber assembly and the outer cylinder is located between the base and the pump head by the rod bolt fastening. Pump outlet located on the same axis of the pump seat.
2, with integrated maintenance-free mechanical shaft seal, reliable, easy to use and maintain.
3, china haina brand vertical multi-stage centrifugal pump compact structure, good looks, low noise, high efficiency.
4, a wide range of uses, can be used to transport from drinking water to chemical medium delivery.
Vertical multistage centrifugal pump maintenance and care:
1, the inlet pipe must be highly sealed, can not leak, leak;
2, prohibit vertical multistage centrifugal pump in the cavitation state of long-term operation;
3, prohibit vertical multistage centrifugal pump operating conditions in large flow, the motor over-current long-term operation;
4, regular check GDL vertical centrifugal pump running motor current value, try to make the pump running in the design conditions;
5, vertical multistage centrifugal pump in operation should have someone care, so as to avoid accidents;
6, vertical multistage centrifugal pump should be carried out every 500 hours for refueling;
7, vertical multistage centrifugal pump after long-term operation, due to mechanical wear and tear, so that unit noise and vibration increase, parking inspection, the need to change into the vulnerable parts and bearings, unit overhaul period is generally one year.
Vertical multistage centrifugal pump in the course of the work, the attack of unpleasant noise and noise, not only hinder the staff thinking, but also affect everyone’s health; noise seizures are: spring cracking, rotary vane noise announced in the work ; Improper installation, the rotor noise when the work of conflict; the vane from the end of a strong squeeze past somewhere from the retracted rotor position jumped out and vertical multistage centrifugal pump cavity hit the noise; parts have burrs, vertical Multistage centrifugal pump cavity into the foreign body or vertical multistage centrifugal pump cavity deformation so that work outbreak hinders the announced noise; vertical multistage centrifugal pump cavity smooth and poor, declared dry grinding noise; harmful space is too large, vertical Multistage centrifugal pump its own attack noise; motor bearings lack of oil, attack dry grinding noise.
