In order to satisfy degree of depth requirement under the liquid, it is long that pump is done usually, and therefore the longest 6～7m that reaches 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 utility model provides the axial-adjustment unit of chemical pump under a kind of improved major axis liquid, it solved existing controlling device can only folk prescription can not bidirectional modulation to adjusting axial clearance problem.
The technical solution of the utility model is as follows:
The axial-adjustment unit of chemical pump under a kind of major axis liquid, 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 adjusting nut, and locking nut also is housed on adjusting nut, and this adjusting nut and locking nut are installed on the axle.
The utility model is by adjustment adjusting nut position on axle, thereby the bidirectional modulation of realization axial clearance after adjusting puts in place, locks axle sleeve, axle and adjusting nut reliably by means of screw, locking nut, lock washer.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 utility model must carry out before assembling finishes, and it is uncontrollable that assembling finishes in back and the pump operation process.The utility model is simple in structure, and is easy to operate, good reliability.
