Description
[technical field]
The present invention relates to the major axis pump, the axial-adjustment unit of chemical pump under particularly a kind of major axis liquid.
[background technique]
Chemical pump is that a kind of its working portion is immersed in the vertical pump in the medium under the major axis liquid, its rotor bearing mode topmost is the corner connection ball bearing that uses in pairs, be mainly used in and bear axial force, rotor deadweight, and restrict rotor axial float and amount of deflection radially, all the other are all sliding bearing, a bearing radial force.
In order to satisfy degree of depth requirement under the liquid, it is long that pump is done usually, and the longest 6-7m that reaches is because of A generally needs to connect axle.From connecing a dimensional chain for assembly as can be known, the normal accumulation of design tolerance is generally 2-5mm.The axial interference of choma and the pump housing, pump cover choma must design axial-adjustment unit before and after the impeller.Axial-adjustment unit commonly used can be referring to Fig. 1.Number in the figure 10 is interstage sleeves, the 11st, and lock washer, the 12nd, rise and cover screw, the 13rd, angular contact ball bearing, the 14th, axle, the 15th, locking nut, the 16th, bearing support, the 17th, bearing bracket, the 18th, bearing gland, the 19th, outside framework oil seal.
As can be seen from Figure 1, bearing support 16 is a Spielpassung with bearing bracket 17, gets H7/h6 usually, and bearing support 16 cylindrical end faces are processed with equally distributed three tapped holes.When needs are adjusted axial clearance, can evenly adjust and cover screw 12, bearing support is promoted a height from bearing bracket; Simultaneously the whole rotor of pump is along with bearing support is done same displacement, thereby reaches the purpose of adjusting axial clearance,
Above-mentioned controlling device is simple in structure, but the shortcoming that exists a maximum is, can only folk prescription to adjusting axial clearance, if choma and pump cover are axially interfered behind the impeller, then powerless.
[summary of the invention]
Task of the present invention provides a kind of improved rotor axial regulator, it solved existing controlling device can only folk prescription can not bidirectional modulation to adjusting axial clearance problem.
Technological scheme of the present invention is as follows:
A kind of rotor axial regulator, it comprises bearing bracket, bearing support, axle through bearing support, be placed in the paired angular contact ball bearing in the bearing support, interstage sleeve, locking nut and outside framework oil seal, be installed in the bearing gland on the bearing support, and rise and to cover screw, on the described axle axle sleeve is housed, axle is a Spielpassung with axle sleeve, angular contact ball bearing is installed on the axle sleeve, and locking nut is installed on the axle sleeve miner diameter end with the axially locating angular contact ball bearing, and the axle sleeve bigger diameter end is provided with the bearing positioning step, the angular contact ball bearing location and installation is in this bearing positioning step, end face at the axle sleeve bigger diameter end is equipped with the joint nut that withers, and locking nut also is housed on adjusting nut, and this adjusting nut and locking nut are installed on the axle.
The present invention is by adjusting adjusting nut position on axle, thereby realizes the bidirectional modulation of axial clearance, regulate put in place after, by means of screw, locking nut,, lock washer locks axle sleeve, axle and adjusting nut reliably.Pump is in startup, running or Umklapp process, and the bearing location is reliable, does not produce between axle sleeve and the axle to move to axial.
Regulative mode of the present invention must carry out before assembling finishes, and it is uncontrollable that assembling finishes in back and the pump operation process.The wood model utility is simple in structure, easy to operate, good reliability.

[specific embodiment]
Referring to Fig. 2, the present invention is the axial-adjustment unit of chemical pump under a kind of major axis liquid, and it is equipped with bearing bracket 27 and bearing support 26, and axle 24 is in bearing support 26.Be positioned to the angular contact ball bearing 23 to using in bearing support 26, interstage sleeve 20 is installed between the angular contact ball bearing 23.Installation shaft pressure cap 28 on bearing support 26, and cover screw 22 and tighten up by rising.
In conjunction with referring to Fig. 3 to Fig. 9, axle sleeve 21 is housed on the shaft part in bearing support 26, axle 24 is a Spielpassung with axle sleeve 21, angular contact ball bearing 23 is installed on the axle sleeve 21.Axle sleeve 21 bigger diameter ends are provided with bearing positioning step 211, and angular contact ball bearing 23 location and installation are in this bearing positioning step 211.Axle sleeve 21 miner diameter ends are processed with outside thread, and locking nut 25 is installed on axle sleeve 21 miner diameter ends with axially locating angular contact ball bearing 23, and the locking nut 25 on axle sleeve 21 miner diameter ends is installed on axle sleeve 21 miner diameter ends by screw thread.
End face at axle sleeve 21 bigger diameter ends is equipped with adjusting nut 34, and locking nut 35 and lock washer 31 also are housed on adjusting nut 34.This adjusting nut 34, locking nut 35 and lock washer 31 are installed on the axle 24.Owing to be processed with screw thread and keyway on this section axle 24, adjusting nut 34 and this screw-thread fit are realized axial clearance regulation by adjusting the position of adjusting nut 34 on axle 24.The effect of keyway is to play the effect locking to adjusting nut 34 with 31 common cooperations of locking nut 35, lock washer.
Be processed with equally distributed through hole at adjusting nut 34 end faces, on axle sleeve 21 bigger diameter end end faces, be processed with along the equally distributed tapped hole of circumference, on axle sleeve 21 bigger diameter ends and locking nut 35, screw 32 is housed, be that the through hole that screw 32 passes adjusting nut 34 is installed in axle sleeve 21 tapped holes, and firmly be connected, and pass through locking nut 35 with reliably locking between axle sleeve 21 and the axle 24 with axle sleeve 21.
The angular contact ball bearing 23 that uses is installed on the axle sleeve 21 in pairs, its inner ring axially locating is respectively by axle sleeve 21 steps and last lower locking nut 35,25, its outer ring and bearing support 26 endoporus cooperate, and the outer ring axially locating is respectively by bearing gland 28 and bearing support 26 endoporus steps.The angular contact ball bearing 23 main bear rotor of using are in pairs conducted oneself with dignity and the bi-directional axial power, restrict rotor axial float and amount of deflection radially.The cooperation of the outside thread of axle sleeve 21 miner diameter ends and last lower locking nut 35,25 realizes the axial restraint and the locking of diagonal angle contact ball bearing 23 inner rings.
By adjusting adjusting nut 34, axle 24 relative axle sleeves 21 are freely moved up and down, and parts such as axle sleeve 21, angular contact ball bearing 23, bearing support 26 do not produce any displacement with respect to bearing bracket 27, thereby reach the purpose of regulating impeller port ring and pump housing choma and pump cover choma axial clearance.After the axial clearance adjustment finished, the through hole that screw 32 is passed adjusting nut 34 firmly was connected with axle sleeve 21, and made between axle sleeve 21 and the axle 24 reliably locking by means of locking nut 35 and lock washer 31.
