英国GRIMM格林进口潜水回流泵 UK GRIMM Imported submersible return pump
UK GRIMM Imported submersible return pump summary:
Department of imported wearable mine pump horizontal single suction multistage centrifugal pump, is the British Green in the integrated absorption of the current basis is successfully developed, the product has the advantages of high efficiency, cavitation performance, wide range of performance, the key is to smooth and reliable operation. The overflow parts are made of wear-resistant materials, and the friction pairs and the clearance parts of the overflow clearance are treated by special process. The utility model is suitable for conveying the muddy mine sewage and other liquids with physical and chemical properties similar to water, and is the most ideal water lifting equipment for coal, mining, metallurgy and other industries.
UK GRIMM Imported submersible return pump structure:
The imported submersible reflux pump with guide rod with automatic positioning fixed, sliding guide bar support as one of the whole water pump parts, generating all weight of the pumps as well as pump thrust all the role in the docking outlet pipe flange. Water pump, accessories and cables can work continuously for a long time without leakage under normal water depth.
Imported diving can move up and down for convenience. Inspection or maintenance personnel do not need to enter the bottom of the pool.
The reflux pump shall be a horizontal single stage structure with vertical single rail and self coupling mounting。 The design of the impeller adopts no blocking and anti winding structure, and the motor and pump body are coaxial through solid particles with diameters of 100mm, 10kW and less。
The return pump can be automatically and securely coupled to the wall pipe and can slide from the top of the tank to the wall pipe at the direction of the guide rod.
The return pump is integrally designed, using closed connections and submersible, and all components of the pump include motors that operate continuously under water.
The impeller shall be made of stainless steel and used for dynamic balancing test. A locking device is arranged between the impeller and the shaft, which is used for preventing the operation from loosing, and the blade is designed as a three piece type. The utility model has the functions of self cleaning and vibration free, and the utility model is a design for the hydraulic transmission without clogging or winding.
The draft tube:
In order to maintain the hydraulic efficiency and reduce the energy consumption, a draft tube is arranged outside the impeller of the reflux pump, and the clearance between the impeller periphery and the draft tube is controlled。
The shaft and the bearing:
The shaft of the return pump and motor is a continuous shaft. The shaft can withstand all axial and radial loads that occur when the impeller rotates. The axis of the impeller is completely isolated from the pumping medium.
The reflux pump motor shaft in two permanently lubricated bearings on the rotating bearing for deep groove ball bearing, main bearing is a spherical ball bearing, wherein the inner bearing ball bearing is used to bear radial force, axial force of the bearing for a bear all by the main bearing。
The sealing of the pump shaft:
Each reflux pump has an oil chamber for the shaft seal system and is equipped with an oil drain device and an inspection screw hole. The oil drain and the check screw hole are easy to enter from outside, so that the oil change work is simpler and easier.
Each reflux pump shall have at least two seals to separate the pump parts。
The impeller wheel and the bearing are provided with two seals to prevent the life of the inner ring mechanical seal and play a protective role.
The seal at the end of the impeller shaft acts as an inserted static / moving ring double mechanical seal. Sealed in an oil chamber that is lubricated by a hydraulic action to overlap the sealing surface at a constant speed. Both internal and external mechanical seals are the latest products to prevent external liquids from entering the oil tank. Both internal and external mechanical seals operate independently.
The pump is used in the oil chamber of the shaft seal system to prevent the full space and the oil expansion in the design, and the leak proof sealing holes and inspection holes are easy to check and maintain from the outside.
The cooling system:
The return pump motor can be cooled sufficiently by the surrounding medium, the larger motor is equipped with an external cooling sleeve, and the back pressure of the pump liquid is used as the motor cycle cooling.
Lifting support system:
The reflux pump is provided with a hoisting hanger with seat and davit. Brake device for hoisting hoist.
Install the lifting support system includes a set of machine per square guide rail, and a special arm type davit, hand chain hoist.
The rigid support of the guide rod is at both ends. The lifting chain includes a water lift ring coupled to the pump.
Such self coupling system:
The water pump of the reflux pump is made of automatic coupling of the flange of the blue face and the through wall pipe, and the efficiency of the pump includes the water passing through the wall pipe. The coupling surface is sealed and reliable, and has self-cleaning function. The self coupling system is an export hard sealing type, and has reliable design guarantee, and the lifting and dropping can not be scratched and destroyed.
