Description
[technical field]
The present invention relates to transmission part coupling technical field, employed adjustable rigid coupling in particularly a kind of vertical pump.
[background technique]
At present, the connecting mode of motor shaft and pump shaft is varied, for vertical structure pump by motor bearing pump rotor weight and operation axial force, the necessary rigid joint of the connection of motor shaft and pump shaft, and pump rotor should be axially adjustable, be convenient to adjust the axial clearance of the pump impeller choma and the pump housing, pump cover, avoid friction or stuck.And in the existing transmission part, also do not have a kind of coupling can satisfy above-mentioned all requirements.
[summary of the invention]
Purpose of the present invention is exactly will solve above-mentioned deficiency and the adjustable rigid coupling that provides a kind of vertical pump to use.It has mainly solved the technical problem of following three aspects: the one, and for the vertical structure pump, the rigid joint of motor shaft and pump shaft; The 2nd, pump rotor axial clearance is adjustable; The 3rd, under the situation of not dismantling motor and pump import and export pipeline, can carry out major tune-up to the axle envelope of pump.
For achieving the above object, the present invention proposes a kind of adjustable rigid coupling, comprise motor coupler 1, divide half snap ring 2, intermediate shaft coupling 3, thread spindle to regulator 4, pump coupling 5, attachment bolt, Cock screw 8, motor shaft 12 adopts the keys motor coupler 1 that is connected, pump shaft 9 adopts the keys pump coupling 5 that is connected, motor coupler 1 one ends adopt bolt to connect intermediate shaft coupling 3, intermediate shaft coupling 3 the other ends adopt bolt connecting thread axial adjustment device 4 and pump coupling 5, and thread spindle adopts the pump shaft 9 that is threaded to regulator 4; The axle head position of motor shaft 12 is provided with circular groove, and branch half snap ring 2 is housed in the circular groove, divides half snap ring 2 to be embedded in the motor coupler 1, on motor coupler 1 and the pump coupling 5 Cock screw 8 is housed.
As needs the machine envelope is overhauled or changed, turn on attachment bolt 6 and attachment bolt 7, remove intermediate shaft coupling 3, thread spindle to regulator 4 and pump coupling 5, machine envelope parts (or unit loading type machine envelope) can take out from the spacing between motor shaft and the pump shaft, import and export at mobile motor and pump under the situation of pipeline, can carry out major tune-up to the axle envelope of pump, shorten the repair time.Adopt adjustable rigid coupling of the present invention, simplify the overhaul procedure of vertical pump, the connecting mode of pump and motor is simple and reliable.
The present invention compared with prior art, novel structure, esy to use, safe and reliable, be provided with middle lengthened coupling, not only satisfy the function of rigid joint and axial adjustment, and install and remove convenient, more change planes the envelope or very convenient to the maintenance of pump, in addition, the present invention makes simply, cost is low, is worthy of popularization.
[description of drawings]
Fig. 1 is a structural representation of the present invention.
Referring to Fig. 1,1 is that motor coupler, 2 is that branch half snap ring, 3 is that intermediate shaft coupling, 4 is that thread spindle is that pump coupling, 6 is that attachment bolt, 7 is that attachment bolt, 8 is that Cock screw, 9 is that pump shaft, 10 is that shaft seal cavity body, 12 is that motor shaft, 13 is a key for machine seals parts, 11 to regulator, 5.
[specific embodiment]
Referring to Fig. 1, be the instantiation that adjustable rigid coupling of the present invention is applied in thermal power plant vertical tube bag condensate extractionpump.Be processed with circular groove and keyway on request at vertical machine axle 12 axle heads, after installing key on the armature keyway, motor coupler 1 is installed on the motor shaft 12.Divide half snap ring 2 to be assembled in the circular groove of motor shaft end, move motor coupler 1 to position toward motor shaft end then, motor coupler 1 after motor coupler 1 axially puts in place, is tightened Cock screw 8 by dividing half snap ring 2 axially locating; Axle head position at pump shaft 9 is processed with screw thread and keyway, and after installing key on the pump shaft keyway, pump coupling 5 is installed on the pump shaft, and thread spindle is assembled on the pump shaft to regulator 4, is connected with screw-thread fit on the pump shaft 9; Intermediate shaft coupling 3 is connected with motor coupler 1 by attachment bolt 6, measure intermediate shaft coupling 3 and the gap of thread spindle between regulator 4, and relatively need to regulate pump rotor axial clearance value, the rotation thread spindle is to regulator 4, making intermediate shaft coupling 3 regulate pump rotor axial clearance with the gap of thread spindle between regulator 4 and needs equates, so just can adjust pump rotor axial clearance as required, thread spindle is drilled with aperture to regulator 4 sides, uses special tool just can rotate thread spindle to regulator 4; Tighten attachment bolt 7 intermediate shaft coupling 3, thread spindle are fixed together to regulator 4 and pump coupling 5, make whole coupling rigid joint.The entire pump rotor part is raised, and is suspended on the motor shaft by dividing half snap ring 2, and coming the bearing pump rotor by motor shaft 12 is weight and operation axial force.The moment of torsion of motor shaft passes to pump shaft by key, the impeller rotation.
When the machine envelope is overhauled or is changed, turn on attachment bolt 6 and attachment bolt 7, remove intermediate shaft coupling 3, thread spindle to regulator 4 and pump coupling 5, machine envelope parts (or unit loading type machine envelope) can take out from the spacing between motor shaft 12 and the pump shaft 9, import and export at mobile motor and pump under the situation of pipeline, can carry out major tune-up to the axle envelope of pump, shorten the repair time.The vertical tube bag condensate extractionpump of firepower electrical plant fitness for purpose machine envelope maintenance or change and be no more than 8 hours is adopted the vertical tube bag condensate extractionpump unit loading type machine envelope of adjustable rigid coupling of the present invention to change and is no more than 4 hours, time decreased half, improve power plant's reliability of operation.
Adjustable rigid coupling transmitting torque scope of the present invention: 200～2338N.m; Spacing between motor coupler and the pump coupling: 200～800mm.
