The utility model is for the proposition of above problem, and a kind of rotor centering of research and design accurately, quick and easy for installation, the horizontal centrifugal pump lower to operator's skill set requirements or the rotor fixed position structure of hydraulic recycling turbine.
Technological means of the present utility model is as follows:
A rotor fixed position structure for horizontal centrifugal pump or hydraulic recycling turbine, rotor is arranged in the rotor mounting hole in rotor casing, the two ends of described rotor by bearings on bearing housing; It is characterized in that, described bearing is radial watt sliding bearing, adopts positioning spigot to coordinate described rotor fixed position between described bearing housing with described rotor casing.
Further, the shape of described rotor mounting hole is consistent with the line of deflection of rotor shaft.
Further, described bearing is the radial watt sliding bearing of selflubricating; After positioning spigot makes described bearing housing install, rotor is at the gap approaches uniformity of each friction vice division chief.The rotating shaft amount of lifting need not be regulated by regulating the jackscrew on bearing housing.After bearing housing is directly installed with rotor casing, just can ensure that the amount of lifting needed for rotor installation.
Further, the rotor shaft amount of the lifting design needed for rotor, according to after the amount of deflection of consideration rotor, is installed in the position of described positioning spigot.
Further, described bearing is the radial watt sliding bearing of pressure lubrication.
Further, described rotor casing and described bearing housing joint are half flange arrangement.
Further, described rotor casing comprises main box body and is arranged on the seal case at described main box body two ends, and described seal case is connected with described bearing housing, and the joint of described seal case and described bearing housing is full flange arrangement.
Compared with the prior art, the rotor fixed position structure of horizontal centrifugal pump described in the utility model or hydraulic recycling turbine has following beneficial effect: rotor is quick and easy for installation, do not need repeatedly to adjust the amount of lifting and just can ensure that rotor is at each friction vice division chief gap approaches uniformity, improves the run stability of equipment.
