鮮肉柜高壓壓力控制器屬冷藏展示柜單體的壓力控制器，其作用是防止壓縮機的排氣壓力過高，一般安裝在壓縮機的排氣出口端。

　　動(dong)作原理：高(gao)(gao)壓(ya)氣體作用于(yu)高(gao)(gao)壓(ya)波(bo)紋(wen)管，當(dang)高(gao)(gao)壓(ya)壓(ya)力低于(yu)高(gao)(gao)壓(ya)給定值下(xia)限(xian)時，高(gao)(gao)壓(ya)調(diao)節(jie)彈(dan)簧(huang)克服(fu)來自波(bo)紋(wen)管的壓(ya)力，將傳動(dong)螺(luo)釘抬起(qi)，微(wei)(wei)動(dong)開關(guan)的按(an)鈕隨之抬起(qi)，電(dian)路接通，壓(ya)縮(suo)機正常運(yun)轉;當(dang)高(gao)(gao)壓(ya)值超過高(gao)(gao)壓(ya)給定值上限(xian)時，高(gao)(gao)壓(ya)波(bo)紋(wen)管壓(ya)力克服(fu)彈(dan)簧(huang)力把(ba)傳動(dong)螺(luo)釘壓(ya)下(xia)，按(an)下(xia)微(wei)(wei)動(dong)開關(guan)的按(an)鈕，電(dian)路斷開，壓(ya)縮(suo)機停(ting)車(che)。

　　The high pressure pressure controller of the fresh meat cabinet belongs to the pressure controller of the refrigerated display cabinet. The function of the controller is to prevent the high pressure of the compressor exhaust, and it is generally installed at the outlet of the compressor.

　　Action principle: high pressure gas acts on high pressure bellows, when the pressure is lower than the lower limit of the given value of high pressure, the pressure regulating spring overcomes the pressure from the bellows, raises the drive screw, the button of the micro switch is raised, the circuit is connected, the compressor runs normally, and when the high pressure value exceeds the upper limit of the given value of the high pressure, the high pressure is higher. Press the bellows pressure to overcome the spring force to drive the screw down, press the button of the micro switch, the circuit is disconnected, and the compressor stops.

　　Low pressure pressure controller for fresh meat cabinet

　　The low pressure controller also belongs to the pressure controller of the refrigerating display cabinet monomer, and its function is to prevent the suction pressure of the compressor from being too low. It is generally installed in the intake port of the compressor, and its configuration and operation principle are similar to that of the high pressure controller. When the low pressure is lower than the lower limit of the normal setting value, the low pressure pressure protector acts so that the compressor stops. When the pressure rises, it can automatically reset and drive. In addition, in the small refrigerated display cabinet refrigeration device, the control of the compressor parking and driving can be controlled directly by the method of controlling the suction pressure directly, and the temperature of the cabinet can be controlled.
