Description
Technical field
The utility model is related to screw compressor manufacturing technology field, especially a kind of vortex electricity for air conditioning for automobiles
Dynamic compressor.
Background technology
There are a kind of swirl motor compressor as illustrated in fig. 1 and 2, including the fixed scroll 6 and movable orbiting scroll being located in shell
9, the scroll portion of movable orbiting scroll 9 is stretched into the scroll portion of fixed scroll 6 to coordinate in the shell portion of fixed scroll 6 and spun, the sliding surface of movable orbiting scroll 9
Mutually slipped by the end face of wear-resistant gasket 10 and bearing block 12, the end face of bearing block 12 passes through wear-resistant gasket 10 and fixed scroll 6
Shell portion is abutted against；Axle 1 of the one end equipped with movable orbiting scroll 9 is by bearing on bearing block 12, and axle 1 is in set on the shaft part at bearing rear
Provided with axle envelope 13；Provided with two passages connected with back pressure cavity 11 between the end face of bearing block 12 and wear-resistant gasket 10, one leads to
Road is connected by being located at the upper drainback passage 8 of fixed scroll 6 with discharge chamber 7, and discharge chamber 7 is formed by shell and fixed scroll 6；One leads to
Road 4 is connected by its lower drainback passage with suction pressure chamber 2, and suction pressure chamber 2 is communicated with suction pressure chamber 21；Suction muffler 2 by shell, fixed scroll 6,
Wear-resistant gasket 10, bearing block 12, axle envelope 13 and axle 1 enclose to be formed；Pressure is provided with the porch of 12 times drainback passages of bearing block
Regulating valve 3, pressure-regulating valve 3 includes the steel ball 32 being located in the inlet screw hole of lower drainback passage, and spring base 34 is screwed in spiral shell
Pit is simultaneously mutually crimped by the spring 33 being arranged at one end with steel ball 32.
During compressor operating, fluid is sucked movable orbiting scroll 9 by movable orbiting scroll 9 under the driving of axle 1 through suction muffler 2 and suction muffler 21
High-pressure fluid is formed in the compression heel row of compression chamber 14 to the discharge chamber 7 for the composition that spun with fixed scroll 6；Partial high pressure in discharge chamber
Fluid can enter by upper drainback passage 8 to be enclosed and is formed by movable orbiting scroll 9, wear-resistant gasket 10, bearing block 12, axle envelope 13 and axle 1
In back pressure cavity 11, then the lower drainback passage of process and pressure-regulating valve 3 enter in suction muffler 2.Therefore, at lower oil return feeder connection
Pressure-regulating valve is installed, it is therefore an objective to which the tolerance for flowing through pressure-regulating valve 3 by its regulation make it that being located at movable orbiting scroll 9 slides surface side
Certain pressure difference is formed between back and suction muffler, the pressure difference and the pressure of effect in compression chamber 14 are cancelled out each other, so that dynamic whirlpool
The pressure that face is slipped between disk 9 and fixed scroll 6, between movable orbiting scroll 9 and bearing block 12 diminishes, and frictional force diminishes, by compressor work
Consumption reduction, abrasion slow down, and the reliability of complete machine is lifted with this.But because spring 33 and steel ball 32 are movement parts, running
Catching phenomenon easily occur causes the backside pressure of movable orbiting scroll 9 to become big extremely, dynamic and static whirlpool mill damage aggravation, and when serious, compressor is short
Failure can be damaged in time, the reliability of swirl motor compressor is substantially reduced.
