Abstract
A single-support suspension type single-stage centrifugal pump, which is characterized in that: the single-disk bearing, installed in the bearing housing of a suspension tackle that is combined as a whole with pump covers, functions to support the pump spindle; the taper surface of the centering taper sleeve socketed on the pump spindle is closely pressed against the inner taper surface of the bearing cover to realize double-support together with the single-row bearing, which facilitates concentricity with the pump body. To ensure accurate penetration of the motor spindle into the spindle sleeve hole of the pump spindle, a wedge liner plate can be placed between the electric motor and the high stand capable of centering. The adjusting bolt on the high stand can be turned to make the motor spindle concentric with the pump spindle. When the motor spindle is inserted into the spindle sleeve hole of the pump spindle, the centering taper sleeve is removed from the inner taper surface to realize a single-support suspension type single-stage centrifugal pump.
Description
The utility model belongs to the pump class in the fluid machinery, and what be specifically related to is single supporting suspension-type single stage centrifugal pump of optimizing structure.
Known to the claimant, the suspension-type single stage centrifugal pump of at present domestic and international widespread production, as Fig. 4, this pump is the dual-supporting suspension-type, and the pump housing has the pump pin 35 times, be fixed on the base, impeller 36, pump shaft 40 and two dish bearings 39 are the main rotor of pump, are the radial force of bearing pump, two dish bearings 39 keep at a certain distance away and are contained in the bearing housing on the suspension 38, cause pump shaft 40 lengthenings; One end of suspension 38 is contained on the pump cover 37, and reliable and stable for guaranteeing suspension 38, the other end connects mutually with base-mounted support 41, plays the aiding support effect; The transmission of pump connects by coupling and motor, for making pump operation steady, when pump is installed, pump shaft 40 is to have certain thickness Shim to realize by adjusting pump pin and motor underfooting with the motor shaft coaxality, obviously do not reach stepless micro-corrective action, cause pump shaft 40 and motor shaft coaxality low, produce bad vibration during pump operation.Because pump shaft 40 lengthenings make the complicated weight of complete machine structure big.
In view of the defective that above-mentioned dual-supporting suspension-type single stage centrifugal pump exists, the design people has developed single supporting suspension-type single stage centrifugal pump.
The purpose of this utility model is on the basis of dual-supporting suspension-type single stage centrifugal pump, overcome existing shortcoming, and provide the list of optimizing structure to support the suspension-type single stage centrifugal pump, impeller, pump shaft and single-deck bearing are the main rotor of pump, it is to compress with bearing gland in the bearing housing of suspension of one that bearing is contained in pump cover, pump shaft inserts brearing bore and by the shaft shoulder and bearing locking nut bearing is clamped, and restriction pump shaft axial motion and radial displacement realize single support structure.Motor shaft, motor flat key directly insert in the axle sleeve hole of pump shaft, and pump shaft is shortened, the weight saving of pump compact integral structure; Pump and motor are contained on the adjustable middle high-base of being furnished with wedge-type backing plate and adjusting nut, turn the adjusting bolt, make the slippage on the high-base in adjustable of wedge-type backing plate, reach high stepless micro-regulating action in the motor, make the relative pump housing of pump shaft and pump cover coaxality height with motor shaft, avoid the bad vibration phenomenon of pump operation generation thus, improved the reliability of pump.
The purpose of this utility model is realized that by following technological scheme it comprises single supporting suspension-type single stage centrifugal pump that foundation the utility model proposes: the pump housing, choma, impeller, impeller nut, pump cover, mechanical seal, pump shaft, bearing locking nut, motor, wedge-type backing plate, adjusting bolt, adjustable middle high-base, accent Intermediate shaft sleeve, bearing gland, bearing.It is characterized in that; Impeller, impeller nut, mechanical seal, bearing locking nut, bearing, pump shaft is the rotor of pump, it is to compress with bearing gland in the bearing housing of suspension-type of one that the single-deck bearing is contained in pump cover, pump shaft inserts brearing bore and by the shaft shoulder and bearing locking nut bearing is clamped, restriction pump shaft axial motion and radial displacement, in order to ensure impeller in pump housing choma to neutrality, the axis hole place design of bearing gland has the bearing gland inner conical surface, be enclosed within that tapered sleeve and bearing gland inner conical surface are adjacent in the accent on the pump shaft, before motor shaft is inserted the axle sleeve hole of pump shaft, limit the swing of pump shaft temporarily, make in the rotor and the pump housing concentric around bearing.In order to make motor shaft accurately insert the axle sleeve hole of pump shaft, place the wedge-type backing plate between motor leg and adjustable middle high-base, turn the adjusting bolt that is contained on the adjustable middle high-base, withstand slippage before and after the adjustable relatively middle high-base inclined-plane of wedge-type backing plate, just can be stepless trace adjust the height and the inclination of motor shaft center line, motor shaft and motor flat key just insert in the axle sleeve hole on the pump shaft restriction pump shaft smoothly around the swing of bearing.After in the axle sleeve hole of motor shaft insertion pump shaft, tapered sleeve pulls away the bearing gland inner conical surface in the accent, realizes single supporting suspension-type.
On the high-base, be that horizontal slotted hole is vertical slotted hole at the bolt hole that the motor location footprint is installed at the bolt hole that pump housing location footprint is installed in adjustable, the bolt hole of wedge-type backing plate is horizontal slotted hole, and the coaxality that guarantees the pump complete machine is just given in three's combination.
The utility model list supporting suspension-type single stage centrifugal pump is compared with existing suspension-type single stage centrifugal pump, has positive effect.It utilizes the rotor of single-deck bearing supporting pump, makes pump structure compacter, and pump shaft is shorter than existing suspension-type single stage centrifugal pump, has improved the rigidity of pump shaft; Tapered sleeve and can realize the adjustable middle high-base of stepless trace during its utilize to be transferred, can guarantee the coaxality of the relative pump housing of pump shaft and pump cover with motor shaft, avoided the choma eccentric wear on the impeller and the pump housing: this model utility is to insert transmission in the axle sleeve hole of pump shaft by motor shaft and motor flat key, pass through coupling transmission coaxality height than existing suspension-type single stage centrifugal pump, thereby can eliminate because the low pump oscillation phenomenon that causes of coaxality makes pump operation more steady reliable.
