Abstract
The invention relates to an adjustable semi-opened impeller wearing resistance structure for pump, 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 at least provided with three screw thread holes along the circumference direction in a same spacing; the wearable plate is provided with screw thread blind holes corresponding to the screw thread holes; any one of the screw thread holes is provided with a press screw; any one of the press screws is provided with a through-hole coaxially; any one of the through-holes is provided with a tension bolt; the tension bolts are provided with nuts respectively positioned at the outer end of the press screw; the tension bolts are respectively connected with the threading 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, the water performance of the pump can be improved.
Description
Technical field:
The present invention relates to mechanical field, relate in particular to mashing pump, particularly mashing pump half-opened impeller, concrete is a kind of adjustable half-opened impeller abrasion-proof structure of pump.
Background technique:
In the design of mashing pump, often adopt half-opened impeller in the prior art, the wearing plate that serves as the half-opened impeller front shroud adopts independent part to be embedded on the pump case, so that processing, assembling and replacing.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, wish that this gap is the smaller the better.People adopt fixed wearing plate at present, and this 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, and manufacture difficulty is increased, and cost of production improves.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 adjustable half-opened impeller abrasion-proof structure that the purpose of this invention is to provide a kind of pump, the adjustable half-opened impeller abrasion-proof structure of described this pump will solve in the prior art gap between the impeller blade and wearing plate can not adjust, cause the unfavorable technical problem of pump performance.
The adjustable half-opened impeller abrasion-proof structure of this pump 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 to same intervals at least three tapped holes, described wearing plate is provided with and the corresponding tapped blind hole of described tapped hole, be provided with one in any one described tapped hole and hold out against screw, any one is described to hold out against and all coaxial in the screw through hole is set, be provided with a turnbuckle in any one described through hole, be provided with a nut on any one described turnbuckle, described nut lays respectively at the outer end that holds out against screw, 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.
