Abstract
The utility model discloses a high-pressure multi-level water-feeding pump, which comprises a stator portion and a rotor portion. The high-pressure multi-level water-feeding pump is characterized in that the stator portion comprises a feeding section, a middle section, a discharge section, a guide vane and a stuffing box, an opening of the discharge section and an opening of the feeding section are both upward perpendicularly, the rotor portion comprises a shaft, an impeller and a balance disc wing shaft sleeve, and the rotor portion is supported by roller bearings at two ends of the shaft. The high-pressure multi-level water-feeding pump utilizes the balance disc wing shaft sleeve structure, can reduce rotary impulsive force of the shaft, is simple in structure and strong in reliability, and can be used for conveying high-temperature medium and realizing fast and high-efficient multi-level water feeding.
Description
Technical field
The utility model belongs to a kind of pump, specifically is a kind of high-pressure multi-stage feed water pump.
Background technique
The high-pressure multi-stage feed water pump belongs to horizontal multi-stage centrifugal pump, and it is suitable for carrying clear water (that is: impure amount is less than 1%, and granularity is less than 0.1mm) and physicochemical properties to be similar to other liquid of clear water.In production application, when tending to because of the pump running, pressure imbalance before and after the impeller on the wheel disc produces end thrust, make rotor department to suction side's play, as not in addition balance will make the impeller and the fixed pump shell joint that run up touch, the wearing and tearing of damaging property make the axial load increasing and generate heat the expanded motor load; Make simultaneously mutually over against impeller and stator be offset, cause and impact and eddy current that reduce the efficient of pump, pump can't drop into operation in the time of seriously.
The model utility content
The purpose of this utility model provides a kind of high-pressure multi-stage feed water pump, can well dissolve a rotational impulse, and is simple in structure, and good reliability can be used for carrying high temperature media, multistage feedwater that can be rapidly and efficiently.
The technical solution of the utility model is as follows:
The high-pressure multi-stage feed water pump, comprise stationary part, rotor portion, it is characterized in that described stationary part includes suction casing, stage casing, Spit Section, stator, stuffing box body, Spit Section mouth and suction casing mouth are all vertically upward, described rotor portion includes axle, impeller, Balance disc Ji axle sleeve, and rotor portion is supported by the roller bearing at axle two ends.
Each part of described stationary part forms by the turnbuckle connection respectively.
Static junction plane between described suction casing, stage casing, the Spit Section seals with paper washer, and each inter-stage of pump adopts the throttling sealing, and the two side shafts envelope of pump adopts packing seal, and bearing adopts the water retaining ring dash.
The utility model adopts Balance disc Ji axle sleeve structure, can well dissolve a rotational impulse, and simple in structure, good reliability can be used for carrying high temperature media, multistage feedwater that can be rapidly and efficiently.
