УСТРОЙСТВО ДЛЯ КОНТРОЛЯ ВЛАЖНОГО ХОДА КОМПРЕССОРА ХОЛОДИЛЬНОЙ МАШИНЫ

摘要

FIELD: refrigerating equipment. ^ SUBSTANCE: invention relates to refrigerating equipment and can be used to protect compressor against hydraulic shock. The proposed device controls the compressor wet circuit in compliance with overheat temperature of sucked-off steam with the help of differential thermo couple. The latter is connected to electronic unit that features a relay characteristic. This unit incorporates the relay component that sends its output signals, via differential RC-circuit, to logical circuit so as to eliminate false operations in starting heat-insulated refrigerator, when steam overheat approximates to or equals zero. Aforesaid logical circuit generates alarm signal only in operation of the compressor. ^ EFFECT: higher sensitivity and validity, ease of assembly. ^ 2 dwg
