Description
Technical field
The utility model relates to the pump series products, mainly is a kind of bidirectional submersed three-flow pump of planetary gear speed-reduction.
Background technique
Along with the technology of China's Submerged Motor Pumps is tending towards full-fledged, and to large scale development.The above diving axle mixed flow pump of 1600 bores has been arranged at present.But through-flow pump maximizes and technical bottleneck occurred, and traditional diving axle mixed flow pump is the direct-connected structure of through-flow pump and motor.Power is big more for submersible motor, and rotating speed is low more, and volume is just big more, and the weight of electric pump is just heavy more, and the power factor of submersible motor is just low more.Motor strengthens simultaneously, has increased the bulb ratio, has reduced through-flow pump efficient.Thereby need energy-saving material-saving, and the high speed rotating speed of motor is dropped to the low speed of pump head, thereby realize through-flow pump motor slim-lined construction, improve efficiency of motor and power factor, improve the efficient of through-flow pump.In order to realize the way traffic of pump, be water pump to be turned around to become turn to this mode inconvenient operation in the existing technology.
The model utility content
The utility model technical problem to be solved provides a kind of bidirectional submersed three-flow pump of planetary gear speed-reduction, and its structural design is simple, the high speed rotating speed of motor is dropped to the low speed of pump head through plane table thermoconductivity meter; Improve efficiency of motor and power factor; Improve the efficient of through-flow pump, adopt Bidirectional vane wheel simultaneously, realize that the water pump forward draws water; Can realize reverse drainage again, easy to operate.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is:
A kind of bidirectional submersed three-flow pump of planetary gear speed-reduction; Include HV submersible motor and through-flow pump; It is characterized in that: also include sleeve; Be provided with support device in the described sleeve, described HV submersible motor and through-flow pump are installed on the support device, between described hyperbaric diving motor and the through-flow pump plane table thermoconductivity meter are arranged; Be connected through the high speed coupling between the output shaft of said hyperbaric diving motor and the input shaft of plane table thermoconductivity meter, the output shaft of said plane table thermoconductivity meter is fixedly connected through low-speed shaft coupler with the input end of the rotating shaft of through-flow pump; The housing of described plane table thermoconductivity meter all is fixedly connected through flange with the HV submersible motor of upper and lower both sides, the housing of through-flow pump; The impeller of said through-flow pump adopts the Bidirectional vane wheel of S type streamline, and the Bidirectional vane wheel of said S type streamline is installed in the rotating shaft of through-flow pump through two-way bearing configuration; Be communicated with inlet tube and outlet tube on the said sleeve.
Also be provided with the cable outlet mouth on the described sleeve.
Bidirectional vane wheel adopts the wing design hydraulic model of S type, can work in the working surface of blade and the back side, and forward is suitable basically with reverse performance.
Through-flow pump, gear reducer and submersible motor adopt the segmentation connecting mode in the utility model, between gear reducer and submersible motor and the through-flow pump are the driving process of motor to be slowed down be delivered to the through-flow pump main shaft.Because the needs of sealing structure, this is connected with two layers of meaning, the one, housing connect, the 2nd, the connection of drive part.
The housing connection is meant the needs for structure; The retarder shell is through forward and backward flange; Connect with submersible motor output terminal flange, through-flow pump input end flange, and carry out static seal, make submersible motor, reduction gear device form the bulb in the axial-flow pump with O shape circle; Water flows through outside bulb during operation, can take away heat for submersible motor, gear-box.This connection belongs to conventional and connects, and the O-ring seals between flange can play seal action reliably.
Drive part is selected planet wheel reduction gear device for use, and its input, output terminal fully take into account the characteristics of submersible motor, the input output of through-flow pump part, have shortened axial length as far as possible.The axle head and the sun gear of input end become one, and shaft extension partly is exactly the external tooth of cydariform coupling; Output terminal and planet wheel become one, and its output is exactly the internal tooth of cydariform coupling.
The coupling of the usefulness that is in transmission connection has also used customed product, and high speed coupling, an end adopt gradually open form spline, directly is enclosed within on the motor output shaft, and the other end is the cydariform internal tooth, is enclosed within on the input shaft part of speed reducer, forms a pair of crowned teeth and cooperates; Low-speed shaft coupler, an end adopts involute splines, directly is enclosed within on the through-flow pump input end, and the other end is made the cydariform external tooth, inserts the output of speed reducer, also forms a pair of crown gear coupling.Crown gear coupling has following characteristics: 1) compensation performance is good, permission diaxon axis angle displacement ± 1.5 °; 2) can bear heavy duty and impulsive load; 3) efficient is high, can reach 0.99.
The utility model has the advantages that:
The utility model structural design is simple, through plane table thermoconductivity meter the high speed rotating speed of motor is dropped to the low speed of pump head, improves efficiency of motor and power factor; Improve the efficient of through-flow pump, adopt Bidirectional vane wheel simultaneously, realize that the water pump forward draws water; Can realize reverse drainage again, easy to operate.
