Sleeve couplings used on Vertical Mixed(Axial) Flow Pumps, semi submersible vertical turbine pumps, and vertical canned condenser pumps with vertical Suspended structures
A sleeve coupling used on a vertical inclined flow pump, a semi submersible vertical turbine pump, and a vertical drum bag condenser pump with a vertical Suspended structure, comprising a sleeve coupling (1), wherein the inner diameter (10) of the sleeve coupling (1) at the mating position with the upper main shaft is 0.5mm smaller than the inner diameter (11) at the mating position with the lower main shaft, and a machining stop (12) is provided in the middle of the inner wall of the mating length, and a slot (9) is provided on the outer wall of the sleeve coupling (1). The disassembly tool includes a first disassembly snap ring (4) and a second disassembly snap ring (5) that is inserted into the corresponding slot (9). The first disassembly snap ring (4) and the second disassembly snap ring (5) adopt a split structure, and the first disassembly snap ring (4) and the second disassembly snap ring (5) are connected as a whole through a long screw (6) and a nut (13). This technology method has a compact structure and is easy to use. It is widely used in vertical inclined flow pumps, semi submersible vertical turbine pumps, and vertical bag condenser pumps with vertical suspension structures. It has strong practical and promotional value. The disassembly tool has a simple structure and reliable performance.
Technical requirements: A sleeve coupling comprising a sleeve coupling (1), characterized in that the inner diameter (10) of the sleeve coupling (1) at the mating position with the upper main shaft is smaller than the inner diameter (11) at the mating position with the lower main shaft, and a machining stop (12) is provided in the middle of the inner wall of the mating length. A slot (9) is provided on the outer wall of the sleeve coupling (1).
