Pump assembly fixing device 1, pump housing sucking pipe through hole 101, flange bracket 102, oil through 103, screw hole 104, the groove 105 of stepping down, pump assembly 2, upper bearing (metal) 201, casing top half 202, frame set 3, screw 4, soldering point 5.
Embodiment
Need to prove, in the situation that do not conflict, embodiment and the feature in embodiment in the application can make up mutually.Describe below with reference to the accompanying drawings and in conjunction with the embodiments the present invention in detail.
Embodiment one:
See also Fig. 2, the invention provides a kind of pump assembly fixing device 1, pump assembly fixing device 1 is the both-side opening cylinder-like structure, and cylinder-like structure is inner for holding compressor pump assembly 2.Offer pump housing sucking pipe through hole 101 on cylindric side, be used for facilitating pump housing sucking pipe to pass through when fixing pump assembly 2.One side of pump assembly fixing device 1 is provided with the flange bracket 102 of Intermediate Gray through hole, and this flange bracket 102 is used for, with upper bearing (metal) or the miscellaneous part of pump assembly 2, coordinating fixedly during pump assembly 2 in pump assembly fixing device 1.Offer oil through 103 and screw hole 104 on flange bracket 102, oil through 103 can make being back to bottom compressor of refrigeration oil; And by screw hole 104 and screw, that pump assembly fixing device 1 and pump assembly 2 is fixing.The outer circumference diameter of pump assembly 2 needs less than pump assembly fixing device 1 internal diameter, makes pump assembly 2 can put into smoothly pump assembly fixing device 1.
Use pump assembly fixing device 1 of the present invention, make the vibration transfer path of pump assembly 2 be changed.The vibration of pump assembly 2 is to be delivered to flange bracket 102 by screw, then by the whole circumferential surface of pump assembly fixing device 1, is delivered to frame set 3, and the damping of bang path is larger like this, and the vibrational energy that is delivered to frame set 3 is less.Pump assembly fixing device 1 covers most of pump assembly 2 simultaneously, and its whole circumferential outer surface and inner walls face fit tightly, and make the rigidity of housing greatly strengthen, and have improved its natural frequency, and vibration noise reduces greatly.
Preferably, pump assembly fixing device 1 also is provided with the groove 105 of stepping down, and when pump assembly fixing device 1 is assembled with frame set 3, is conducive to reduce the hot jacket of pump assembly fixing device 1 or the unbalance stress of colding pressing, thereby reduces the distortion on support plane like this.
As shown in Figure 3 and Figure 4, the present invention also provides a kind of compressor that uses pump assembly fixing device 1, pump assembly fixing device 1 hot jacket or cold pressing with frame set 3 in; Pass by screw 4 screw hole 104 of being located at respectively on flange bracket 102 simultaneously and the screw hole of being located on casing top half 202 from bottom to top is fixed.This moment flange bracket 102 lower surfaces and casing top half 202 upper surface laminatings.So design can also be adjusted the position of rotor with respect to stator inner hole by screw, guarantees that the air gap between stator and rotor is even, reduces vibration noise.
