UK GRIMM imported horizontal multi-stage centrifugal pump summary:

imported horizontal multi-stage centrifugal pump is a horizontal single suction multistage segmented centrifugal pump. It adopts the hydraulic model of high efficiency and energy saving products recommended by Green in England, and occupies the leading position in the industry. The utility model has the advantages of high efficiency, wide performance range, safe operation and balance, low noise, long service life, convenient installation and maintenance, etc.. Any other liquid that provides clear water or physical or chemical properties similar to water. It can also change the flow passage parts, seals, and add cooling systems to transport hot water, oil, corrosive or abrasive media. Products to implement ASME B73 standard "multi-stage centrifugal pump type and basic parameters" standards.

UK GRIMM imported horizontal multi-stage centrifugal pump characteristic:

imported horizontal multi-stage centrifugal pump is composed of shell parts, rotor parts, balance structure, bearing parts and sealing parts.

1.Shell part:

The shell part is mainly composed of a suction section, a middle section, a spit section, a guide vane, a back section, a bearing body and the like, which are bolted together. The direction of rotation of the pump, from the end of the drive, the pump rotates clockwise.

2.Rotor part:

The rotor part mainly consists of the shaft and the impeller, shaft sleeve and balance plate which are mounted on the shaft. The shaft parts are fastened by flat keys and sleeve nuts, so that the shaft and the shaft become one body, and the whole rotor is supported in the pump casing by both ends of the bearing. The number of rotors in the middle part of the rotor is determined according to the pump number.

When the pump is in use, the shaft seal must be connected with water sealed. Water seal is used in two conditions: one is the use of the first impeller of water, and the other is to quote foreign water. As shown in Table 3, the water sealed with water is referenced as an external seal water, and the water sealed with the first stage impeller is not used as the seal water. The degree of tightness of the packing gland must be appropriate, when the liquid can drop drop by drop. When the temperature of the medium transported is higher than 80 ℃, cooling water must be introduced into the packing gland and seal cooling chamber, cooling water and water are the external reference room temperature water, cooling water pressure is 1.5-3kg/m3, water pressure is higher than that of the seal cavity is 0.5-1kg/m3. Each type of pump water seal and seal cooling chamber, but the water pipeline interface position is different, the pipeline interface in the axial position see the pump structure.

3.Balance mechanism:

The balancing mechanism is composed of a balance ring, a balance sleeve, a balance disc and a balancing pipeline.

4.Bearing part:

The bearing part is mainly composed of bearing body and bearing. This pump bearing has two kinds of sliding bearings and circulation. Bearings are not subjected to axial force, the pump in operation, the rotor part in the pump housing should be able to freely move the axis of the earth, can not use radial ball bearings.

5.Sealing and cooling of pump:

The suction section, the middle section, the spit section and the guide vane of the shell part are coated with molybdenum disulfide grease to seal.

The rotor part and the fixed part are sealed by a sealing ring, a guide vane sleeve and a filling. When the wear degree of the seal ring and guide vane sleeve has affected the work and performance of the pump, it should be replaced in time.

UK GRIMM imported horizontal multi-stage centrifugal pump structure description:

1.The pump inlet and outlet are in the pump axis below the horizontal axis and vertical position, the pump shell. In the open, it is unnecessary to remove the water discharge pipe and a motor (or other prime movers) to see from the coupling to the pump, pump are inverse to the needle. Rotation. In accordance with the user's special order requirements, can also be changed to inch needle rotation.

2.Pump main components are: pump body, pump cover, impeller, shaft, double suction sealing ring, shaft sleeve, bearings and so on. The shafts are made of high quality carbon steel, and the remainder are made of cast iron. The pump body and the pump cover form the working chamber of the impeller, and the screw holes for installing the vacuum meter and the pressure gauge are arranged on the water inlet and the water outlet flange, and the lower part of the inlet and outlet water flanges is provided with a water outlet pipe hole.

3.The impeller is static balanced, fixed by the sleeve and the sleeve nuts on both sides. Its axial position can be adjusted through the sleeve nut, the axial force of the impeller with the symmetrical arrangement of its blades to achieve balance, there may be some residual bearing axial force which is coaxial end bearing.

4.The pump shaft is composed of two single row radial ball bearing, bearings mounted in the bearing body at both ends of the pump body, with lubrication, double suction to reduce the water pressure water chamber drain back to the suction chamber sealing ring.

5.The water pump is directly driven by the motor through the coupling.

6.The shaft seal is a soft packing seal, in order to cool, lubricate the sealing cavity and prevent leakage of air into the pump, there is a water seal between the packings. When the pump works, a small amount of high-pressure water flows through the water seal pipe into the packing chamber and acts as a water seal.

UK GRIMM imported horizontal multi-stage centrifugal pump technical parameter:
