Abstract
Claims
1. A sump type oil separation crankcase for a refrigeration compressor comprising an upper cover (8) and a lower cover (1), characterized in that: The lower cover (1) is fixedly connected to mounting blocks (2) on both sides. The mounting blocks (2) have slots (3) at their upper ends. The lower cover (1) is fixed with card blocks (4) at all four corners. The card blocks (4) have first threaded holes (5) on opposite sides. Each slot (3) is equipped with a plate (6). The upper end of the plate (6) is fixedly connected to a connecting block (7) on the side near the top cover (8). The four corners of the lower end of the top cover (8) are provided with slots (9). The side of the slot (9) near the first threaded hole (5) is provided with a second threaded hole (10). The connecting blocks (7) on both sides of the top cover (8) are provided with sliding grooves (11). The sliding blocks (12) are slidably connected in the sliding grooves (11). The side of the sliding blocks (12) is fixedly connected to a connecting plate (13). The connecting plates (13) are provided with a third threaded hole (14). The third threaded hole (14) is threadedly connected to a first screw (15).
2. A slotted oil separating crankcase for a refrigeration compressor according to claim 1, characterized in that: The outer walls of the upper cover (8) and the lower cover (1) are fixedly connected to symmetrically arranged connecting pieces (16), and a fourth threaded hole (17) is opened through each connecting piece (16). The fourth threaded hole (17) is threadedly connected to the second screw (18).
3. A slotted oil separating crankcase for a refrigeration compressor according to claim 1, characterized in that: A sealing ring is fixedly connected at the connection between the upper cover (8) and the lower cover (1). The sealing ring is a multi-layer composite sealing ring, consisting of an inner layer of fluororubber, an intermediate layer of polytetrafluoroethylene, and an outer layer of nitrile rubber from the inside out. Lips are provided on both sides of the sealing ring, and the lips form a tight contact with the surfaces of the upper cover (8) and the lower cover (1).
4. The grooved oil separator crankcase for a refrigeration compressor according to claim 1, characterized in that: A turntable is fixedly connected to the wall of both the first screw (15) and the second screw (18).
