Abstract
The utility model discloses a capacity adjustment system of a semi-closed standalone double-screw refrigeration compressor. The capacity adjustment system consists of a circulating pump, a group of oil piston, a capacity adjustment sliding valve, at most four capacity adjustment electromagnetic valves and a controller, wherein the capacity adjustment electromagnetic valves are classified into two groups and are connected with the oil piston and the capacity adjustment sliding valve through oil pipes; the capacity adjustment sliding valve is also connected with the circulating pump through an oil pipe; the controller consists of an oil temperature sensor, an oil pressure sensor, a data processor and double-direction controllable silicon. Compared with the conventional capacity adjustment system, the capacity adjustment system disclosed by the utility model has the advantages that the number of the capacity adjustment electromagnetic valves and the use amount of relevant oil paths are reduced, the structure of the system is effectively simplified, the response speed of the system is increased, and the energy consumption of the capacity adjustment system is reduced. Meanwhile, the automation degree of the capacity adjustment system is further increased, and the monitoring for a working state of the capacity adjustment system is also enhanced; the stability of the capacity adjustment system is effectively improved.
Description
Technical field
The utility model belongs to refrigeration plant field, is specifically related to a kind of semiclosed unit two-stage screw bolt refrigerant compressor and holds adjusting system.
Background technique
Along with improving constantly of refrigeration industry development and energy-saving and emission-reduction consciousness, semiclosed unit two-stage screw compressor has obtained using widely with its outstanding power savings advantages, but how to bring into play its maximal efficiency, reduce energy consumption, improving the use longevity is current important topic, the normal 3 stops that adopts is held adjusting system at present, capable of regulating power scope has 25%, 50%, 100% 3, its system is by recycle pump, a displacement-regulating sliding piece, five solenoid valves and two groups of appearances adjust piston to form, although can meet the needs that market is used, but this system oil-way is complicated, during adjustment, reaction velocity is slow, and need to expend more energy consumption, therefore traditional appearance adjusting system is still restricting popularization and the use of semiclosed unit two-stage screw compressor.
Summary of the invention
The utility model object is just to overcome above-mentioned deficiency, provides a kind of semiclosed unit two-stage screw bolt refrigerant compressor to hold adjusting system.
For achieving the above object, the utility model is to be achieved through the following technical solutions:
A kind of semiclosed unit two-stage screw bolt refrigerant compressor holds adjusting system, by recycle pump, oil piston, hold and adjust guiding valve, hold and adjust solenoid valve and controller to form, described oily piston is one group, hold and adjust solenoid valve to be no more than 4, described appearance adjusts solenoid valve to be divided into two groups, and all adjust guiding valve to be connected with oily piston and appearance by oil pipe, described appearance adjusts guiding valve separately by oil pipe, to be connected with recycle pump, described controller is by oil temperature sensor, oil pressure sensor, data processing system and bidirectional triode thyristor form, wherein data processing system respectively with oil temperature sensor, oil pressure sensor and bidirectional triode thyristor electrical connection, described data processing system separately arranges data communication port, described oil temperature sensor and oil pressure sensor are arranged on oily internal piston, another and the recycle pump of described bidirectional triode thyristor, hold and adjust guiding valve, hold and adjust solenoid valve electrical connection.
According to PORT COM, it is RS232 port.
The more traditional appearance adjusting system of the utility model, reduced to hold and adjusted solenoid valve and relevant oil circuit use amount thereof, effectively simplified system architecture, improved system response time, reduced appearance adjusting system energy consumption, this novel also further raising is held adjusting system automaticity and to holding the monitoring of adjusting system working state, effectively promotes the stability of holding adjusting system simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is this novel electric theory diagram.
