Condensate pump installation, the installation method of the condensate pump

Common is condensate water pump, condensate pump is mainly used in the thermal power thermal system conveying the condensate in the condenser. Generally liquid temperature does not exceed 80 ℃, the pump inlet pressure is not higher than 0. 6MPa。

the role of the condensate pump is put in the condenser hot well water by the low pressure heater into the deaerator, maintain level condenser heat stability and guarantee of deaerator water, is to meet the requirements of production process and not a waste of electricity, so keep the safe and reliable operation of the condensate pump is critical. Condensate pump work is under the condition of high vacuum conveying close to the saturation temperature of the water.

when a centrifugal pump of the condensate pump starts, with the pump shaft to drive the impeller for high speed rotary motion, forcing filling liquid between blade rotation in advance under the effect of inertial centrifugal force, the liquid from the impeller center to the peripheral radial motion. Liquid in the movement process to obtain the energy flows through the impeller, static pressure can be increased, the flow velocity increases. When liquid left after entering the pump casing, impeller slowdown due to shell port gradually expand, part of the kinetic energy is converted to static pressure can, finally along the tangential flow into the discharge line. So the volute pump casing is not only a part of fluid from the impeller, and can turn another device. When the liquid from the impeller center into peripheral at the same time, form the low pressure area, the impeller center in the center of the holding tank liquid level and the impeller under the action of total potential energy difference, the liquid was sucked into the impeller center. Rely on the impeller's spinning, fluid and continuous suction and discharge. Fluid in centrifugal water pump mechanical energy finally show the decompression can improve.

condensate pump installation method:

1, the structure of the condensate pump is single base, which is simplified combined with mounting plate is located in the base layer of the pit, and spit out bend suspension rotor are connected to the mounting plate, motor is vertically installed on turn out, and the condensate pump rigid connection or flexible connection.

2, condensate pump suction chamber is airtight simplified cavity, the suction on the outer body located in the base layer under the ditch and connected to condenser drainpipe; The direction of condensate water pump discharge nozzles are horizontal.

3, located in the outer body suction bell, suction segment ( body) , in the middle, guide vane, pump cover, sealing ring, bearing, spit out period of pressure water to take over the connection through the poles, such as a pump body and suspension in turn out.

4, by the heads of the impeller of pump rotor components, secondary impeller, shaft sleeve, lock bolt, interval sets, spacer sleeve, sleeve coupling spindle, etc.

5, according to the traffic requirements suction conditions, head for the double suction impeller forms, while the secondary for single suction guide vane type or single suction oblique flow type.

6, to balance the pressure inside the cylinder in the suction chamber and condenser, inhaling indoor gas generated, improve and stable inhalation of indoor and outdoor gas, inhaled can improve and stability and has a balance between condensate pumps and suction room management system.
