英国GRIMM格林进口多级双吸中开泵 UK GRIMM Imported multi stage suction pump
UK GRIMM Imported multi stage suction pump summary:
Imported multi stage suction pump is a two stage double suction horizontal centrifugal pump. It is a new generation of two level horizontal centrifugal pump designed and developed by Green technology in the United kingdom. The pump can replace the traditional segmental multistage pump for the transportation of clean water, liquid containing a small amount of solid particles and the use of corrosive liquids. The utility model is suitable for building water supply, industrial boiler, fire fighting, mine water supply and drainage, chemical industry, and various industrial water supply systems, etc..
UK GRIMM Imported multi stage suction pump technological advantage:
1. The two stage impeller back form, axial force balance. Automatically canceled many pumps necessary balance disc structure, the reliability of the pump and the failure rate is greatly improved, especially to speed changes, the viscosity of the liquid applications.
2。 Shorter bearing span, increase the rigidity of the shaft, make the pump more stable and quiet, especially adapted to the need for quiet water supply occasions。
3. The flow range expanded to 1000m3/h, to fill the general multi-stage pump market gaps.
4. Excellent hydraulic model, pump efficiency is higher than the same parameter multi-stage pump, more energy saving, more environmentally friendly.
5. The level of the pump casing, pump inlet and outlet located in the lower part of the pump shell, maintenance, no need to remove the motor and pipeline, the operation is very convenient, so as to shorten the maintenance time, reducing the use cost.
UK GRIMM Imported multi stage suction pump structure characteristics:
1. The suction and discharge ports of the pump are located in the lower part of the pump case. The level of placement on both sides now. With the pump axis of 90 degrees angle. The pump body is horizontally opened, so that the utility model is convenient to disassemble, and the motor and the pipeline need not be disassembled when the utility model is checked and repaired, and the operation is extremely convenient.
2。 pump main parts are: pump seat, pump cover, two impeller, pump shaft, bearing seat and sealing ring and so on。
3. The main structure of this pump: two impellers are fixed on the pump shaft by the impeller stop sleeve and the sleeve nut. In order to reduce the leakage of the liquid in the extruding chamber into the suction chamber, a sealing ring is arranged at the suction port of the two impellers. The support of the pump shaft is composed of two single row centripetal thrust ball bearings at one end of the coupling, and the other end adopts two single row radial ball bearings. The bearings are lubricated by grease or by thin oil. Single row radial thrust ball bearings, bearing the radial forces of the rotor, also bear the axial thrust of the remainder of the impeller after the natural balance of the impeller is symmetrically arranged. A vacuum chamber is arranged at the lower part of the bearing, and the cooling water can be poured into the bearing to cool the bearing when the temperature of the bearing exceeds the allowable temperature. The transported liquid enters the first stage impeller and passes through the first impeller outlet, and the liquid enters the second stage impeller along the inner flow passage, and then is discharged to the water outlet pipe through the second stage impeller. Screw pump in the highest position and a square plug plugged in, for the pump before starting the vacuum pump connected to draw water into the air in the pump housing. The pump is composed of a direct drive motor through flexible coupling.
4. The general form of pump seal with packing seal; suction end is provided with a packing ring, packing seal, suction side needed to run water from the first stage pump discharge chamber through a water seal pipe connected packing ring, the size of the water through the valve can be adjusted; the discharge end packing required lubricating water is high pressure water by second impeller inlet chamber of self lubrication. When the sealing performance requirements are high, mechanical seals can be used. The mechanical seals are composed of moving rings, stationary rings, pressing elements and sealing elements.
