Abstract
The invention relates to an energy adjusting mechanism in the semi-closed screw rod type refrigerating compressor. The energy adjusting mechanism comprises a sliding valve (1) and a matching groove (11) which can move in the sliding valve (1); a gas returning hole of an economizer (12) and a liquid spraying hole (13) are respectively arranged on the sliding valve (1) and the matching groove (11) and at the moving direction of the matching groove (11). The energy adjusting mechanism has the advantages that the gas return state of the systemic economizer is changed along with the change of the load; the pressurized liquid spraying state in the compressor is changed along with the change of the load; the liquid spraying way of the compressor is closed under the low load state.
Description
Technical field
The present invention relates to a kind of semi-closed screw type refrigerating compressor, relate in particular to capacity controlling gear in a kind of semi-closed screw type refrigerating compressor.
Background technique
As everyone knows, in screw compressor, special capacity controlling gear is arranged, thereby it can make compressor change its running state along with the change of external load to reach energy-conservation effect.
But in traditional design, compressor energy adjustment structure Design only can make the effect optimization of economizer and liquid spray under the full load state, and when compressor operating during in partial load, because the cause of its return-air, hydrojet change of state uses economizer and liquid spray system can have influence on this systematic function.
Summary of the invention
The technical issues that need to address of the present invention have provided capacity controlling gear in a kind of semi-closed screw type refrigerating compressor, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions:
The present invention includes: guiding valve, the mating groove that can move at guiding valve; Economizer return-air hole and liquid spray orifice are being set respectively on described guiding valve and the mating groove and on the direction that mating groove moves.
Compared with prior art, the invention has the beneficial effects as follows: the return-air state of systematic economy device is changed along with the change of load; Hydraulic fluid spray state is changed along with the change of load; Compressor liquid spray pattern under low load condition is closed.
Description of drawings
Fig. 1 is the structural representation of the present invention under normal state;
Fig. 2 is the structural representation of the present invention under low load condition;
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:
By Fig. 2, Fig. 3 as seen: the present invention includes: guiding valve 1, the mating groove 11 that can move at guiding valve 1; Economizer return-air hole 12 and liquid spray orifice 13 are set respectively on described guiding valve 1 and mating groove 11 and on the direction that mating groove 11 moves;
Distance is identical with the maximum moving distance of mating groove 11 between described economizer return-air hole 12 and the liquid spray orifice 13.
The present invention is respectively applied to the spray of economizer return-air and liquid by making a call to two through holes at guiding valve, along with During load variations, guiding valve also moves forward and backward in casing, and two holes on the guiding valve are also along with guiding valve at this moment Move and move, thereby realize the effect that it can spray under different conditions. In addition, owing to cooperate The cause of groove, when entering low load running at compressor, its guiding valve is shifted to the exhaust side of compressor, This moment, the liquid spray orifice was mated the groove isolation, was compressor automatically stop solution spray under low load condition. Logical Cross the present invention, can make economizer and liquid be sprayed on the fractional load state and be issued to the effect optimization, effectively Realized that the full load state is energy-conservation.
Claims (2)
1. capacity controlling gear in the semi-closed screw type refrigerating compressor comprises: guiding valve (1), the mating groove (11) that can move at guiding valve (1); It is characterized in that: upward and on the direction that mating groove (11) moves economizer return-air hole (12) and liquid spray orifice (13) are set respectively at described guiding valve (1) and mating groove (11).
2. capacity controlling gear in the semi-closed screw type refrigerating compressor according to claim 1 is characterized in that: distance is identical with the displacement distance of mating groove (11) maximum between described economizer return-air hole (12) and the liquid spray orifice (13).
