JGGC High Pressure Water Pump
Model-JGGC sub-high pressure multistage boiler feed water pump is designed and made according to advanced technology abroad. This product is made of stainless steel plate, through the process of pressing, drawing and welding, which has been widely used for industrial boiler's feed water in developed countries. Compared with domestic casting processing pump, it has the features of small volume, light weight, high efficient, energy saving, small vibration, low noise, evenly turn long service life, vertical mounted, small ground occupation, which can be described as an ideal upgrading energy saving product.
In addition to water supply, drainage system and boiler feed, it is also widely used for pressure container feed water, tall building feed water, farm irrigation, pressurized in fire control, wine making, medicine, chemical industry, aquaculture, environmental protection and machine matching etc.
Model-JGGC series pump is vertical multistage centrifugal pump. Motor is directly connected to pump shaft through link block above the pump. Water inlet is on the pump base, and outlet is on the base as well, making down suction down discharge piping type. According to user's requirement, up vomiting type i.e. water outlet is on the motor base of upper pump.
The liquid transported from inlet section to impeller 2 through fluid director3, under the action of high speed spinning blade, increasing kinetic energy and potential energy of liquid. After liquid enters diversion apparatus pressure room, speed decreases, kinetic energy changes into potential energy. Liquid passes through lead vane to enter second - grade impeller; get second increment, continuously go on, potential energy gradually adds. The more series centrifugal impeller grades are, the higher water pressure of outlet is. Lastly, pressure water passes through outlet diversion apparatus 12 entering into round tube 11 with diversion 6 formed line clamping case from the base outlet drains off.
The dynamic seal between pump axle 10 and motor base 13 is mechanically sealed, and its friction pairs of the rotating rings are made of hard alloy for its good seal effect and long service life.
The inlet ring part of impeller2 adopts the labyrinth seal formed by floating sealing ring 17. It can be replaced when floating seal rings wear out. The fluid direction bearing is made of cermet, and the inner ring of bearing matched with it is made of hard alloy to ensure reliable operation.
Impeller and fluid direction is made by stainless steel plate, through the process of punching, stretching and welding. Spline shaft and cylinder are all stainless steel, with the advantages of tight structure, light weight, corrosion resistance.
The axial thrust of this series of pumps is borne by motor bearings. The axial channeling momentum of the pump rotor is within the range of 1-3mm. In order to prevent the front and back covers of the impeller from rubbing with the flow guide, the momentum of the motor's rotor should not exceed 1mm. Users should also change the motor bearings while overhauling the water pump.
