Abstract
The utility model relates to an adjustable immersible pump in spiral impeller clearance of big passageway, including the pump body, pump seat, pump body cross-under pump shaft, pump shaft joint impeller, the impeller is arranged the pump body in and is connected with the pump seat of pump body lower extreme, and the external screw thread that connects the adjusting nut periphery on the last horizontal flange of pump seat, adjusting nut hole internal thread connect the locking bolt soon, and the locking bolt lock connects the pump body, and adjusting nut's up end laminating supports terminal surface under the pump body, and adjusting nut's inside and outside screw thread revolves to opposite. The adjustable impeller and pump seat abrasion-resistant device is simple in structure, errors and abrasion gaps caused by abrasion in machining and long-term use can be conveniently adjusted, the gap between the impeller and the pump seat is controllable, and leakage and influence on the operation power of the pump are prevented.
Description
Technical Field
The utility model relates to a immersible pump, the spiral impeller clearance adjustable immersible pump of big passageway specifically says so.
Background
The submersible pump is used for conveying sewage media and is generally provided with the large-channel impeller to ensure no blockage, and the spiral large-channel impeller is a novel blockage-free impeller, has stronger large-particle passing capacity and can even convey live fish. However, the clearance between the open type blade and the pump seat is matched by the contour curve, the curve is completely controlled by the machining precision of the impeller and the pump seat part, the clearance of the impeller cannot be ensured due to the accumulated assembly error, the leakage seriously affects the efficiency when the clearance is too large after the assembly, and the interference and the friction are easy when the clearance is too small.
Disclosure of Invention
The utility model provides a simple structure, error, the wearing and tearing clearance that can convenient regulation impeller and pump seat caused because of processing, long-term use wearing and tearing ensure that the clearance of impeller and pump seat is controllable, prevent to reveal and influence the adjustable immersible pump in big spiral impeller clearance of passageway of pump operation power.
The utility model adopts the technical proposal that: the utility model provides an adjustable immersible pump in spiral impeller clearance of big passageway, includes the pump body, pump seat, and pump body cross-under pump shaft, pump shaft joint impeller, the impeller is arranged in the pump body and is connected and pump seat of pump body lower extreme, its characterized in that: the upper horizontal flange of the pump base is screwed with the external thread on the periphery of the adjusting nut, the internal thread of the inner hole of the adjusting nut is screwed with the locking bolt, the locking bolt is locked and connected with the pump body, the upper end surface of the adjusting nut is attached to the lower end surface of the pump body, and the internal thread and the external thread of the adjusting nut are opposite in screwing direction.
The pump seat still is equipped with circumference joint section, sets up multichannel sealing washer laminating pump body end opening inner wall on the circumference joint section.
The hardness of the adjusting nut is greater than that of the pump body and the pump seat.
And the upper end surface of the adjusting nut is provided with a nut flange for supporting the pump body.
The utility model discloses an adjustable support pump body lower extreme face about adjusting nut cross-under on the horizontal flange of pump seat, accomplish adjustable when impeller and pump seat produce the clearance because of machining error or use wearing and tearing from this to ensure that the clearance of impeller and pump seat is controllable, prevent to reveal, effectively ensure the rated operation power stability of pump simultaneously.

Fig. 1 is a schematic structural diagram of the present invention.
In the figure: the pump comprises a pump body 1, a pump shaft 2, an impeller 3, a pump seat 4, an upper horizontal flange 5, a circumferential joint section 6, a sealing ring 7, an adjusting nut 8 and a locking bolt 9.
Detailed Description
The following further description is made in conjunction with the accompanying drawings and examples.
FIG. 1 shows: the utility model provides an adjustable immersible pump in spiral impeller clearance of big passageway, including the pump body 1, the pump shaft 2, impeller 3, pump seat 4, adjusting nut 8, locking bolt 9, 1 cross-under pump shaft 2 of the pump body, the pump shaft connects impeller 3, impeller 3 arranges in the pump body 1 and connects in the pump seat 4 with pump body lower extreme, the external screw thread of 8 peripheries of adjusting nut is connected on the last horizontal flange 5 of pump seat, adjusting nut hole internal thread connects locking bolt 9 soon, the locking bolt lock connects the pump body, adjusting nut's up end laminating supports pump body lower extreme terminal surface, adjusting nut's interior, the external screw is revolved to opposite.
In this embodiment, the pump base is further provided with a circumferential bonding section 6, and a plurality of sealing rings 7 attached to the inner wall of the lower opening of the pump body are arranged on the circumferential bonding section.
In order to ensure the stable support, the hardness of the adjusting nut is greater than that of the pump body and the pump base, and a nut flange for supporting the pump body is arranged on the upper end face of the adjusting nut.
Claims (4)
