Abstract
Aconnecting device for a vertical major-axis submerged pump comprises a motor connecting sleeve, an axial clearance adjusting device, and a pump shaft connecting sleeve. The motor connecting sleeve is arranged on a motor shaft; external threads are formed at the upper top end of a pump shaft; corresponding internal threads are formed in the intracavity of the axial clearance adjusting device; a plurality of through holes are formed on the surface of the axial clearance adjusting device; and the through holes are used for connecting the motor connecting sleeve, the axial clearance adjusting device, and the pump shaft connecting sleeve. In the utility model, the axial clearance adjusting device can be rotated to adjust the pump shaft to move up and down and ensure that impellers rotate in the optimum interspace; and the connecting device is adopted to be fixed with the motor connecting sleeve, thereby minimizing axial play and radial play of the pump, avoiding the adoption of a guide bearing, reducing cost, lowering noise, facilitating installation and maintenance, and prolonging service life.
Description
Technical field: the utility model relates to a kind of pump, particularly relates to a kind of connection set of vertical long shaft submerged pump.
Background technique: traditional vertical long shaft submerged pump, general major axis length is less than 5 meters, and pump duty is little, and used power of motor is also little.In order to guarantee the steady of major axis running, reduce axial force and radial force, adopt the multistage guide bearing, because the flow of pump is little, power of motor is little, so general bearing can meet design requirement.And work as long shaft submerged pump axial length greater than 7 meters, when flow also need increase, at this moment, power of motor also will increase, and will require the pump shaft diameter to increase accordingly, like this will be very difficult when selecting bearing, adopt general bearing to be easy to heating, short, the not steady phenomenon of operation of life-span, adopt extraordinary specification bearing, cost an arm and a leg, cost up, repair demolition are extremely inconvenient.
Summary of the invention: the purpose of this utility model is exactly the connection set that a kind of vertical long shaft submerged pump will be provided, and it can overcome the existing problem of above product well.The purpose of this utility model is achieved in that a kind of connection set of vertical long shaft submerged pump, is by the motor connecting sleeve, the axial clearance regulation device, and the pump shaft connecting sleeve is formed, and it is characterized in that: motor shaft is provided with the motor connecting sleeve; The top is provided with outside thread on pump shaft, the inner chamber of axial clearance regulation device also is provided with corresponding internal thread, the surface of axial clearance regulation device is provided with several through holes, is used for the connection of bolt with motor connecting sleeve, axial clearance regulation device, pump shaft connecting sleeve.The utility model axial rotary slack adjuster, can adjust the upper and lower of pump shaft moves, guarantee that impeller turns round under best clearance, adopt connection set and motor connecting sleeve to fix, can reduce the axial float and the radial-play of pump to greatest extent, can not adopt guide bearing, reduced cost, reduce noise, installation, maintenance is convenient, has prolonged working life.
Description of drawings: Fig. 1 is the utility model structural representation;
1. motor, 2. motor connecting sleeve, 3. axial clearance regulation device, 4. pump shaft connecting sleeve, 5. pump shaft.
Embodiment: the utility model is described in further detail below in conjunction with accompanying drawing;
In the drawings, a kind of connection set of vertical long shaft submerged pump is by motor connecting sleeve 2, axial clearance regulation device 3, and pump shaft connecting sleeve 4 is formed, and it is characterized in that: 1 in motor is provided with motor connecting sleeve 2; The top is provided with outside thread on pump shaft 5, the inner chamber of axial clearance regulation device 3 also is provided with corresponding internal thread, the surface of axial clearance regulation device 3 is provided with several through holes, is used for the connection of bolt with motor connecting sleeve 2, axial clearance regulation device 3, pump shaft connecting sleeve 4.During concrete enforcement, the gap too hour is rotated down the axial clearance regulation device between impeller and front pump cover, and pump shaft is moved up; The gap too hour between impeller back and rear pump cover, rotate up the axial clearance regulation device, pump shaft is moved down, guarantee that impeller turns round under best clearance, because the surface of axial clearance regulation device is provided with several through holes,, the axial clearance regulation device can connect with motor connecting sleeve, pump shaft connecting sleeve so being transferred on any position.Adopt connection set and motor connecting sleeve to fix, can reduce the axial float and the radial-play of pump to greatest extent, can not adopt guide bearing, reduced cost, reduce noise, installation, maintenance is convenient and safe reliable, and Duo one times or more than the multiaxis structure working life.
