Abstract
A self-priming pump connecting device comprises an upper coupler, a key A and a bolt. The upper coupler is arranged on a motor shaft, the key A is arranged between the motor shaft and the upper coupler, a fastening screw is arranged on the upper coupler, a key B is arranged between the upper coupler and a lower coupler, and the upper coupler and the lower coupler are connected and locked through the bolt. The lower coupler and a pump shaft are integrally arranged, the pump shaft is provided with a shaft sleeve which is sleeved with a mechanical sealing component, a sealing ring is arranged at the lower end of the mechanical sealing component, the lower end of the shaft sleeve is provided with an impeller which is fixed on the pump shaft through an impeller nut, and sealing gaskets are arranged between the shaft sleeve and the impeller and between the impeller and the nut. The self-priming pump connecting device is small in vibration, low in noise, flexible in moving, simple and convenient to dismount and easy to mount, avoids up-and-down moving and left-and-right swinging of the pump shaft, completely eliminates the phenomena of 'running, protruding, dripping and leaking', and prolongs the service life of equipment.
Description
Technical field:
The utility model relates to pump, refers more particularly to coupling device of self-sucking pump.
Background technique:
Present coupling device of self-sucking pump, the gap is big, vibration is big, noise is big, motion is uneven, causes pump shaft play and swinging up and down, has had a strong impact on working efficiency and the working life of self-priming pump, and great majority all can use packing seal or packing_seal or mechanical seal below the pump coupling arrangement, so pump inevitably can produce " run, drip, leak " phenomenon.
Summary of the invention:
The purpose of this utility model provides a kind ofly to be avoided the play up and down of pump shaft and swings, and reduces vibration, increases the service life, and avoids the coupling device of self-sucking pump of " run, drip, leak ".
The utility model is achieved in that coupling device of self-sucking pump, comprise upper coupling, key A, bolt, it is characterized in that: motor shaft is provided with upper coupling, be provided with key A between axle and the upper coupling, upper coupling is provided with Cock screw, between upper coupling and the following coupling key B is set, and by bolt upper coupling is connected locking with following coupling, described coupling down and pump shaft are arranged to one, pump shaft is provided with axle sleeve, is arranged with mechanical sealing assembly on the axle sleeve, and the mechanical sealing assembly lower end is provided with seal ring, the axle sleeve lower end is provided with impeller and is fixed on the pump shaft by impeller nut, axle sleeve and impeller, be provided with sealing gasket between impeller and the nut.
The utility model has been avoided the play up and down of pump shaft and has been swung, and has reduced vibration, has prolonged working life, has avoided " run, drip, leak " phenomenon.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
Among the figure 1, motor, 2, key A, 3, Cock screw, 4, upper coupling, 5, key B, 6, bolt, 7, pump shaft, 8, axle sleeve, 9, mechanical seal, 10, sealed environment, 11, key C, 12, impeller, 13, impeller nut, 14, sealing gasket.
Embodiment:
Below in conjunction with accompanying drawing the utility model is further described:
With reference to accompanying drawing, coupling device of self-sucking pump, comprise upper coupling 4, key A 2, bolt 6, it is characterized in that: 1 in motor is provided with upper coupling 4, be provided with key A 2 between axle and the upper coupling 4, upper coupling 4 is provided with Cock screw 3, between upper coupling 4 and the following coupling 7 key B5 is set, and upper coupling 4 is connected locking with following coupling 7 by bolt 6, described coupling down and pump shaft 7 are arranged to one, pump shaft 7 is provided with axle sleeve 8, be arranged with mechanical sealing assembly 9 on the axle sleeve 8, mechanical sealing assembly 9 lower ends are provided with seal ring 10, and axle sleeve 8 lower ends are provided with impeller 12 and are fixed on the pump shaft 7 by impeller nut 13, axle sleeve 8 and impeller 12, be provided with sealing gasket 14 between impeller 12 and the nut 13.During concrete enforcement, upper coupling is provided with Cock screw, makes upper coupling be positioned on the motor shaft like this, can not rotate and can not move up and down by any direction; Between upper coupling and following coupling, key B is set, and by bolt upper coupling is connected locking with following coupling, make so not removable and upper and lower between upper coupling and the following coupling above and below can not play; Following coupling and pump shaft arrange all-in-one-piece, so coupling can be pump shaft again down, so the pump shaft vibration is little, noise is little, can avoid pump shaft play and swing up and down, and be easy to dismantle, install and repair.Because the mechanical seal lower end is provided with seal ring, is provided with sealing gasket between axle sleeve and impeller, impeller and the nut, such seal arrangement has effected a radical cure the phenomenon of " run, drip, leak ", has prolonged the working life of equipment.
