[model utility content]
The utility model provides the heating capacity and high-temperature refrigeration ability that improve compressor, directly can switch between unit compressor and compound compressor, unit compression is used when specified refrigeration, adopt Two-stage Compression high-temperature refrigeration, specified heating with during low-temperature heating, improve the change stage compressor of high-temperature refrigeration ability and heating capacity.
In order to realize above-mentioned model utility object, the technical solution adopted in the utility model is:
A kind of change stage compressor, comprise motor stator, rotor, bent axle, upper roller, lower roller, upper flange, upper cylinder, dividing plate, lower cylinder and lower flange, upper and lower roller to be arranged on respectively on bent axle and in upper and lower cylinder chamber rotary work, the casing wall of upper cylinder offers vane slot, in vane slot, is equipped with the upper slide plate with upper rollers co-operate work, upper flange is provided with and controls the device for controlling sliding vane that upper slide plate action makes the upper cylinder selectivity participation compression work of compressor, described device for controlling sliding vane comprises the plunger hole being opened in upper flange radial direction, spring, plunger, pull bar and control valve, described control valve is installed on the upper flange wall edge place of plunger hole end and is communicated with low-pressure gas end with the pressurized gas end of compressor respectively by pipeline, described pull bar is fixedly connected with plunger and passes plunger hole and stretches in the upper vane slot of upper cylinder, upper slide plate offers coordinate with the drag hook on pull bar lead kerve, described spring is promoting plunger and pull bar outwards moves along the direction of plunger hole under tension force effect, pull bar pulls slide plate away from upper roller.
Described pull bar is fixedly connected with adopting screw between plunger.
The beneficial effects of the utility model are:
The utility model by having the plunger hole of a cooperation plunger back and forth movement on upper flange, be designed with the spring, pull bar and the screw that coordinate and come and go plunger motion simultaneously, pull bar is undertaken fastening integral with plunger by screw, control valve is installed on the upper flange wall edge place of plunger hole end and is communicated with low-pressure gas end with the pressurized gas end of compressor respectively by pipeline; The operation of plunger runs under the control valve gas high and low voltage exchange of outer end and the effect of Compress Spring, upper slide plate offers coordinate with the drag hook on pull bar lead kerve, whether pull bar controls slide plate and normally works, to realize the switching of single twin-stage under the running state of plunger; During single-stage, upper slide plate is pulled outwardly by pull bar, make slide plate can not with upper roller conflict cisco unity malfunction, only have the lower roller in lower cylinder to carry out compression work, gas is discharged to upper cylinder by dividing plate, then from upper flange discharge, formed one stage of compression; During twin-stage, pull bar is inside, and upper slide plate recovers normal work, realizes Two-stage Compression.Controlled by the change level of compressor, the efficiency requirement of specified refrigeration can be met when unit compressive state, high-temperature refrigeration amount can be improved when Two-stage Compression state, significantly promote heating capacity advantage.
