Description
Technical field
The present invention relates to a kind of sliding blade apparatus of rolling rotor type compressor, particularly a kind of sliding blade apparatus of transfiguration rolling rotor type compressor.
Background technique
The internal structure of the rolling rotor type compressor of existing two cylinders, as shown in Figures 1 and 2, the compressor of sealing is equipped with compression assembly 1 and electric machine assembly 2.Compression assembly comprises two cylinders, be respectively first cylinder 3.1 and second cylinder 3.2, be separately installed with the first piston 4.1 and second piston 4.2 in each cylinder, and be installed in first slide plate 6.1 and second slide plate 6.2 in cylinder first vane slot 5.1 and second vane slot 5.2 respectively, the eccentric crankshaft of driven plunger, eccentric crankshaft comprises eccentric crankshaft main shaft 7.1 and eccentric crankshaft countershaft 7.2, on the support eccentric crankshaft, lower bearing 8.1 and 8.2, separate the intermediate clapboard 9 of two cylinders up and down, the eccentric crankshaft that drives by electric machine assembly 2 passes torque to the first piston 4.1 and second piston 4.2, the pressurized gas of cylinder compression are discharged to system side by enclosure interior from discharge pipe 10, therefore, pressing in the housing is the high pressure side.The back of first slide plate 6.1 of first cylinder 3.1 is connected with the pressure spring 6.1.1 that promotes the slide plate action, the motion of slide plate is provided by the elastic force of 6.1.1 during compressor start, is just moved by high pressure in first vane slot 5.1 and common first slide plate 6.1 that promotes of pressure spring 6.1.1 behind the compressor start; Second slide plate, 6.2 backs of second cylinder 3.2 then do not promote the spring of vane motion, and second vane slot 5.2 and withdrawing hole 5.4 forms airtight slide plate chambers and be connected an end of penstock 11; The other end of penstock 11 connects pressure switching valve 12, the pressure switching valve can flow to penstock 11 with compressor housing inner high voltage and the switching of air-breathing low pressure, in penstock 11 high pressure, then second slide plate, 6.2 proper motion work, cylinder has compression exhaust; Be low pressure in penstock 11, then second slide plate 6.2 stops in the vane slot 5.2, and cylinder does not compress no exhaust; Cylinder 3.2 switches between exhaust and not exhaust, and then compressor forms the variation of air displacement, and the transfiguration function is achieved.
It more than is typical variable volume compressor working principle, its operation is fairly simple, but, here have a problem: second slide plate, 6.2 backs of second cylinder 3.2 are not owing to install pressure spring, so its freedom of movement is bigger, turning round particularly in stateful switchover process, just stop by working to, or by stopping to reworking, the second slide plate back can bump with the withdrawing hole wall, collide and to cause second slide plate and heavy wear of withdrawing hole wall even breakage when serious, directly cause compressor reliability significantly to reduce, therefore must improve this situation.
Summary of the invention
