Abstract

The invention relates to a semi-opened impeller wearable plate adjustment device, which consists of a wearable plate and a pump body, wherein, the wearable plate is arranged inside the pump body; a column-shaped tube is arranged in the middle of the wearable plate; a column surface is arranged inside the pump body; the column-shaped tube is matched with the column surface, a gap is arranged between the wearable plate and the inside of the pump body; one end of the pump body is provided with three screw thread holes and three light holes along the circumference direction, the three screw thread holes and the three light holes are arranged in an intercrossing manner; the wearable plate is provided with screw thread blind holes corresponding to the light holes; any one of the screw thread holes is provided with a press screw; any one of the light holes is provided with a tension bolt; the tension bolts are provided with nuts respectively positioned outside the pump body; the tension bolts are respectively connected with the screw thread blind holes on the wearable plate. The tension bolts and the press screws are used to fix and adjust the position of the wearable plate, thereby the gap between the impeller and the wearable plate can be adjusted, and the water performance of the pump can be improved.

Description

Adjusting device for half-opened impeller wearing plate
Technical field:
The present invention relates to mechanical field, relate in particular to mashing pump, the particularly half-opened impeller wearing plate of mashing pump, concrete is a kind of adjusting device for half-opened impeller wearing plate.
Background technique:
In the prior art, mashing pump adopts half-opened impeller, is embedded on the pump case as the wearing plate of half-opened impeller front shroud, can be convenient to processing, assembling and changes.And the gap length between impeller blade and the wearing plate directly influences the hydraulic performance and the working life of pump.Under the situation that does not influence normal operation, this gap is the smaller the better.Present wearing plate is fixed, and structure can not be adjusted, and wants to guarantee that the gap delta value between impeller blade and the wearing plate meets design requirement, and just must improve the machining accuracy of correlated parts, manufacture difficulty is increased, the cost of production raising.Simultaneously, because wearing plate can not be adjusted, after the wearing plate wearing and tearing, the gap increases between wearing plate and the impeller, and the pump hydraulic performance descends, even can't normally use, and causes equipment to scrap in advance.
Summary of the invention:
The purpose of this invention is to provide a kind of adjusting device for half-opened impeller wearing plate, described this adjusting device for half-opened impeller wearing plate will solve in the mashing pump of prior art the gap between the impeller and wearing plate can not adjust, cause the unfavorable technical problem of pump performance.
This adjusting device for half-opened impeller wearing plate of the present invention is made of the wearing plate and the pump housing, described wearing plate is arranged on pump housing inboard, the middle part of wearing plate is provided with cylindrical tube, pump housing inboard is provided with the cylndrical surface, described cylindrical tube matches with the cylndrical surface, wherein, be provided with the gap between the inboard of the described wearing plate and the pump housing, one end of the described pump housing along the circumferential direction is provided with three tapped holes and three unthreaded holes, described three tapped holes and three unthreaded holes are alternate uniform, described wearing plate is provided with and the corresponding tapped blind hole of described unthreaded hole, be provided with one in any one described tapped hole and hold out against screw, be provided with a turnbuckle in any one described unthreaded hole, be provided with a nut on any one described turnbuckle, described nut lays respectively at the outside of the pump housing, and described turnbuckle is connected with tapped blind hole on the wearing plate respectively.
Further, be provided with O-ring seals between the cylndrical surface of the cylindrical tube at wearing plate middle part and pump housing inboard.
Working principle of the present invention is: mashing pump is when assembling, if the gap of impeller and wearing plate is undesirable, perhaps mashing pump is after using after a while, and wearing plate weares and teares, the gap of impeller and wearing plate increases, can adjust the position of wearing plate among the present invention, during adjustment, unclamp the nut on the turnbuckle earlier, rotate then and hold out against screw, ideal value is adjusted in gap between wearing plate and the impeller, tightened the nut on the turnbuckle then, can finish adjustment.Simultaneously,, also can realize reaching the performance parameter of expection, thereby improve overall efficiency by changing the gap of impeller and wearing plate.
The present invention and prior art contrast, and its effect is actively with tangible.The present invention is provided with the gap between the inboard of the wearing plate and the pump housing, utilize turnbuckle and hold out against the position that screw fixes and regulate wearing plate, thereby can regulate the gap of impeller and wearing plate, improves the hydraulic performance of pump.

Fig. 2 is the structure enlarged diagram of the local I among Fig. 1.
Fig. 3 is the structure enlarged diagram of the local I I among Fig. 2.
Embodiment:
As Fig. 1, Fig. 2 and shown in Figure 3, adjusting device for half-opened impeller wearing plate of the present invention is made of the wearing plate 1 and the pump housing 2, described wearing plate 1 is arranged on the pump housing 2 inboards, the middle part of wearing plate 1 is provided with cylindrical tube, the pump housing 2 inboards are provided with the cylndrical surface, described cylindrical tube matches with the cylndrical surface, wherein, be provided with the gap between the inboard of the described wearing plate 1 and the pump housing 2, one end of the described pump housing 2 along the circumferential direction is provided with three tapped holes 4 and three unthreaded holes 5, described three tapped holes 4 and three unthreaded holes 5 are alternate uniform, described wearing plate 1 is provided with and described unthreaded hole 5 corresponding tapped blind holes 6, be provided with one in any one described tapped hole 4 and hold out against screw 9, be provided with a turnbuckle 7 in any one described unthreaded hole 5, be provided with a nut 8 on any one described turnbuckle 7, described nut 8 lays respectively at the outside of the pump housing 2, and described turnbuckle 7 is connected with tapped blind hole 6 on the wearing plate 1 respectively.
Further, be provided with O-ring seals 10 between the cylndrical surface of the cylindrical tube at wearing plate 1 middle part and the pump housing 2 inboards.
Regulate turnbuckle 7 and the position that holds out against screw 9, can fix and regulate the position of wearing plate 1, thereby can regulate the gap of impeller 3 and wearing plate 1.
