Abstract
The utility model discloses a refrigerator with an automatic protector. The refrigerator comprises an external circulating system, an internal circulating system and an electric control cabinet thereof, wherein the external circulating system is used for refrigerating circulating water through a compressor; and the internal circulating system is used for cooling the compressor through a condenser. Flow switches for sending out control signals to the electric control cabinet are respectively arranged at water outlets of the external circulating system and the internal circulating system. The refrigerator has the beneficial effects that signal lines are connected and guided from flow switch end lines to the electric control cabinet of the refrigerator; when no water flow caused by system water shortage or water pump damage and other reasons occurs in the external circulating system or the internal circulating system, the flow switches send out no-water flow signals; a power supply of a main machine is automatically cut off to protect the compressor; and the flow switches can send out buzzer alarms to remind maintenance personnel of timely maintaining.
Description
Technical field
The utility model relates to a kind of refrigeration machine, especially a kind of refrigeration machine with automatic protection.
Background technology
The operation principle of the refrigeration machine of existing use is: will cool off to the hydronic water in workshop through compressor; Compressor can produce a lot of heats in cooling procedure; For making the compressor operate as normal, dispose cooling column and the heat that compressor produces is taken away through condenser.The configuration no automatic safety device usually that dispatches from the factory of this refrigeration machine is in its operation process, if the water pump fault; Perhaps system water source and cooling water source disappearance then can not normal circulation, and compressor is still in running order; Can cause overheat of compressor, and even cause damage.
The utility model content
The technical problem that the utility model will solve provides a kind of refrigeration machine with automatic protection, when the water pump fault occurring, can realize automatic shutdown protection to compressor when perhaps system water source and cooling water source lack.
For solving the problems of the technologies described above; The technical scheme that the utility model is taked is: a kind of refrigeration machine with automatic protection; Comprise through compressor being the external circulating system of recirculated water refrigeration, being internal circulation system and the electrical control cubicles thereof that compressor cools off, the flow switch that can send control signal for electrical control cubicles is set respectively at the delivery port of external circulating system and internal circulation system through condenser.
Adopt the beneficial effect that technique scheme produced to be: to connect from flow switch terminals line and draw holding wire to refrigeration machine electrical control cubicles; And be connected with auxiliary reclay, main frame contactor in the switch board; When external circulating system or internal circulation system appearance no current (reasons such as system's lack of water or water pump damage cause) phenomenon; Flow switch sends no current signal; Cause the auxiliary reclay relay of electric cabinet by the transmission of flow switch signal line; Auxiliary reclay cuts off host power supply automatically by the main frame contactor, the protection compressor; And flow switch can send the buzzing chimes of doom, reminds the maintenance personal in time to keep in repair.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation.
Fig. 1 is the structural representation of the utility model.
Wherein, 1-compressor; The 2-condenser; The 3-electrical control cubicles; The 4-flow switch; The 5-thermometer; 6-external circulating system delivery port; 7-internal circulation system delivery port.
The specific embodiment
The utility model comprises through compressor 1 and at external circulating system delivery port 6 and internal circulation system delivery port 7 flow switch 4 that can send control signal for electrical control cubicles 3 to be set respectively for the external circulating system of recirculated water refrigeration, through internal circulation system and electrical control cubicles 3 thereof that condenser 2 cools off for compressor.
Connect from flow switch 4 end lines and to draw holding wire to refrigeration machine electrical control cubicles 3; When external circulating system or internal circulation system appearance no current (reasons such as system's lack of water or water pump damage cause) phenomenon; Flow switch 4 sends no current signal; Auxiliary reclay main control system contactor through in the electrical control cubicles 3 cuts off host power supply automatically, protection compressor 1; And flow switch 4 can send the buzzing chimes of doom, reminds the maintenance personal in time to keep in repair.
Claims (1)
1. be with the refrigeration machine of protection automatically for one kind; Comprise through compressor and be the external circulating system of recirculated water refrigeration, be internal circulation system and the electrical control cubicles thereof that compressor cools off that it is characterized in that: the delivery port at external circulating system and internal circulation system is provided with the flow switch that can send control signal for electrical control cubicles respectively through condenser.
