Abstract: A system and method for monitoring and controlling oil return to a compressor, characterized by monitoring and controlling oil level, oil temperature, and compressor outlet pressure, so as to determine whether the oil level is lower than a predetermined level threshold, whether the temperature in the lubricating oil box is lower than a predetermined temperature threshold, and whether the compressor outlet pressure exceeds a predetermined pressure threshold, so as to control the flow of lubricating oil returned to the oil box by controlling the valve opening of the oil return valve according to a non-segmentation principle or a segmentation principle, ensure sufficient lubricating oil in the oil box, and enhance efficiency of the system.

Abstract: A signal connector includes a main body and positioning device. The main body has a front section with an end connector and a rear formed by an accommodating groove with a threaded hole and insert hole. The positioning device is received into the accommodating groove of the main body, composed of a clamping piece and screwing elements. The clamping piece is at the bottom of the groove, with a threaded hole. The screwing element is inserted through the insert hole and secured in the threaded hole. After foresaid are combined, the conducting filament of a transmission line can be tightly clamped by the clamping piece by rotating the screwing element to move the clamping piece upward, ensuring enhanced signal transmission.
