Vertical multistage centrifugal pump working principle

The working principle of haina brand vertical multistage centrifugal pump is a centrifugal pump on the effect of rotating impeller on the liquid of the prime mover mechanical energy transmitted to the liquid.As a result of the action of vertical multistage centrifugal pump in the process of the liquid flowing from impeller import export, its speed can be increased, and pressure can be impeller discharge of liquid through the pressure out of the room, most of the speed can be converted to pressure, and then along the discharge pipe to go out, at this point, the impeller inlet vacuum or low pressure, formed by the liquid discharge and suction pool of liquid in the role of liquid surface pressure (atmospheric pressure), by the impeller of the imported, so the rotating impeller is continuous inhalation and discharged liquid.
Vertical multistage centrifugal pump installation steps:
1. Check the pump and motor before installation of idle condition.
2. The vertical multistage centrifugal pump installation location should be near the water as much as possible
3. There are two ways to get the pump and the base installation, one kind is directly in the cement on the basis of rigid connection, the other is to adopt flexible connection JGD type damper installed.
4. Installation of pumps can be placed directly on the basis of higher 30-40 mm (preparation of filling slurry). And then correcting, and wear a good anchor bolt, filling cement mortar, after 3 ~ 5 days after the cement dries up. Recalibration, after being completely dry cement, tighten the anchor bolt nut.
5. Installation of piping outlet pipe should have their own support, should not make the flange pipe under too much weight of the pump.
Vertical multistage centrifugal pump disassembly of the problems that should be paid attention to:
1) before removing, the pump should be within the medium discharge completely.And if the corrosive medium, after emissions should be clean with clear water.
(2) when the disassembly, should be removed the paragraphs of housing, impeller, key parts are arranged in a row, such as Numbers, not mess, when back to pack general back in the original order.Try not to open some assembly is pulled down.
(3) parts to should take put down gently, not knock against, can’t hurt, can’t fall to the ground.
(4) during the period of maintenance, to avoid someone to close the power switch or open the valve material and cause an accident, the power switch can be locked, and the material tube and blind flange.
(5) shall not be loose anchor bolt of the motor, lest affect installation pump alignment.
China haina Vertical multistage centrifugal pump energy saving, cover an area of an area small, easy installation, stable performance, etc.Can fully satisfy the high-rise buildings, deep well mining of water supply and drainage and fire control facilities, such as hot and cold water or general medium is the general industry, the physical and chemical properties such as water liquid conveying the best pump type.Vertical multistage centrifugal pump product use: used for conveying water or other liquid physical properties like water, use medium temperature does not exceed 80 ℃, and suitable for energy, metallurgy, wood processing, chemical industry, textile, papermaking, hotels and restaurants, bathroom, etc.For hot water boiler pressure cycle transport and urban heating system cycle pump, using the medium temperature does not exceed 120 ℃.Vertical multistage centrifugal pump is suitable for the textile, petroleum, chemical industry, medicine, health, food, oil refining and other industrial chemical corrosive liquid.
