英国GRIMM格林进口潜水贯流泵 UK GRIMM Imported submersible pump
UK GRIMM Imported submersible pump summary:
New mechatronics products imported submersible axial-flow pump is combined with submersible motor technology and tubular pump technology and produce, while maintaining the advantages of tubular pump itself, and use of the submersible motor, but also overcomes the traditional tubular pump motor cooling, cooling, sealing and other problems.
UK GRIMM Imported submersible pump characteristic:
The product has the following characteristics:
1.The inlet and outlet water head loss is small, the pumping station device efficiency is high.
2.Under the same working conditions, the power allocation of the motor is small and the operation cost is low.
3。The pump foundation does not need to set suction trough, excavation amount is small。
4.Pump tube straight, suitable for removal of the upper tall plant, can not build factories, cars to replace fixed crane hoisting.
5。Save the amount of excavation, and the engineering costs, construction costs, reducing installation area, saving pumping station project total cost 30 ~ 40%。
6。Quick installation and easy installation。
UK GRIMM Imported submersible pump structure description:
Imported submersible tubular pump is horizontal structure, from the pump inlet, the impeller counterclockwise rotation。
Impeller with advanced hydraulic model conversion, the performance of good, stable and mature. Select smaller nD value, good anti cavitation performance, ensure smooth operation.
Smaller products using two independent sets of mechanical seal, the larger product adopts stratified shear packing seal or mechanical seal under different seal combination to adapt to different structure, to ensure reliable sealing, and can realize online repair.
Imported submersible pump is equipped with multi-channel protection device, which can lead the lead to the electric control box。 Protective devices are: overload, lack of phase, leakage, excessive temperature, humidity, flooding and so on (depending on the structure of the pump is different)。
4。Pump / motor shaft:
Small pump and motor shaft coaxial, compact structure, as short as possible, and improve the stiffness, deflection from design will be controlled within the allowable range, running small vibration, seal and bearing life longer; large pump adopts gear transmission structure.
5.Pass through the water channel:
By using CFD and experiment method, the streamline shape of runner is determined, and the operation efficiency is guaranteed。
The shell of the motor transfers heat directly to the surrounding medium and is taken away by the surrounding water. The high power and high voltage motor adopts the patented technology of inner duct heat dissipation, which makes the three-phase winding rise at low temperature and the temperature field is even.
High performance squirrel cage induction motors, designed especially for submersible pumps, comply with GB755 standards. The insulation grade is F, and the highest working temperature is 135 centigrade. Depending on the power, the 380V, 660V, 3KV, 6KV, 10KV and other voltage levels can be adopted. The two VPI insulation process is adopted to ensure the insulation reliability of the high voltage motors.
The bearings are made of rolling bearings, capable of withstanding all axial and radial loads and are completely separated from the medium conveyed by the pump.

UK GRIMM Imported submersible pump main use:
Imported submersible pump is suitable for large flow and low lift occasions. It is mainly used for rainwater drainage, industrial and agricultural water use, regional water diversion, especially for water conservancy and flood control projects with comprehensive consideration of drainage and irrigation. If the bidirectional tubular pump is adopted, the positive pumping and reverse drainage can be realized only if the steering of the motor is changed.
UK GRIMM Imported submersible pump installation form:
Imported submersible pumps generally use dry installation (pump pit without water, the unit is dry around, can be normal maintenance). The two ends are connected with the pipe by a telescopic joint. The installation system for pre embedded steel plate, two foot bolt and two telescopic joint. Embedded steel for one-time embedded parts, embedded in concrete and steel reinforced will lower inserted reinforcement welding; the foot bolt can be an embedded, can be two times the pre buried section; both ends of the telescopic two embedded parts.
When you first install the submersible axial-flow pump into the pre buried steel plate, then on the basis of the position of the connecting bolt and embedded steel plate welding. If the foot bolt is a embedded in the foot bolt as a positioning reference; if the foot bolt two times embedded, can be carried out in the submersible pump in place. Then, according to the design drawing, the height of the tubular pump is adjusted by the wedge, so that it meets the requirement of elevation, and finally the pump position is fixed. Axial force of water pump running by the foot bolt and the pre buried steel plate connection bolts.
Then, the two expansion joints are connected with the water inlet and outlet of the pump to determine the expansion joint position, then the exposed steel bar and the expansion joint are welded, and finally the two grouting is carried out。
Overhaul, such as the need to pump the lift, first closed the door, the pump will flow off the water in the road release, drain the pump pit, and then enter the water at both ends of the expansion joint to loosen, you can pump the pump from。 The installation also takes place only in reverse order。
