Description
Technical field
The present invention relates to scroll compressor, more specifically, the present invention relates to one high side to low side release gas under overvoltage or scarce fluorine working order, thus the scroll compressor that protection Moving plate and quiet disc mechanism are not damaged.
Background technique
In refrigeration systems, when there is blocking, refrigerator leakage in pipeline, scroll compressor just there will be superelevation back pressure or scarce fluorine running phenomenon, this can cause the mechanism such as the second scroll and the first scroll cause wearing and tearing because of high pressure or high temperature abnormality or break, in the fault of compressor, this phenomenon occupies great majority.The general measure adopted in refrigeration industry: 1, a kind of is install high-pressure pressure sensor and low-pressure sensor additional in the refrigeration pipe of compressor suction, exhaust side, when the high pressure of perception, low pressure exceed high pressure, low pressure safety range time, circuit board can send instruction, cuts off compressor power.This method not only cost is high, and control circui is complicated, and due to low-pressure sensor reliability low, compressor can not be protected very well; 2, another kind is that compressor inside arranges protective function, and high voltage protection and scarce fluorine running protection are divided into Liang Ge mechanism.Lacking fluorine running protection is by relief opening set temperature distortion video disc, and when scrollwork core temperature is because lacking that fluorine running is abnormal to be raised, temperature video disc is out of shape and gets through relief opening and low-pressure cavity passage, to low-pressure cavity make-up gas.This method complex structure, parts are many, cost is high, and due to the existence of exhaust ports one-way valve, and when making temperature anomaly, hyperbaric chamber well to low-pressure cavity make-up gas, can reach good protected effect.
