Abstract
The utility model discloses a vertical type subsurface slurry pump, which comprises a motor support, a bearing body part, a mounting plate, a support plate, a main shaft, a protective plate, an impeller, a volute, a filter screen and a water outlet pipe part, wherein an abrasion-proof shaft sleeve and two round nut for adjusting are arranged on the lower end of the main shaft, a screw thread step and a step matched with the abrasion-proof shaft sleeve are processed on the lower portion of the main shaft, the abrasion-proof shaft sleeve and the main shaft are matched through a small gap, and the inner surface of a center hole of the protective plate is processed to be a step shape with a protruded upper portion. The vertical type subsurface slurry pump protects the impeller from being rubbed, prolongs service life of the impeller, also reduces processing dimensional accuracy requirements, reduces production cost, and improves universality of product parts.
Description
Technical field
The utility model relates to a kind of slag stock pump, is specifically related to a kind of vertical slag slurry pump under liquid novel impeller and adjusts and protect new structure.
Background technique
Vertical slag slurry pump under liquid is that single-stage, single-suction cantilever structure are used for carrying solidliquid mixture and the corrosivity slurry that contains the finite concentration solid particle, generally immerse in the slag stock tank or in hole and work, without any need for shaft seal and shaft seal water, easy for installation, occupied ground is little, without advantages such as any leakages and be widely used in the industries such as mine, metallurgy, electric power, coal, chemical industry, building materials.Length under pump insertion liquid, between 800mm～1500mm, if necessary, can be worn suction pipe.Transmission is arranged on motor cabinet by vertical type motor, with coupling or belt pulley, with pump, is connected.The spiral case suction port, with filter screen, can prevent that large particle from advancing in people's pump.Outside meeting user's performance requirement, the assembling of pump and maintain and replace flow passage components easily damaged parts convenience and be also to react slag slurry pump under liquid design important indicator to impeller and quick, the simple to operate property of gap adjustment of backplate.
As shown in Figure 1 and Figure 2, traditional vertical slag slurry pump under liquid liquid mainly is comprised of electric machine support 1, bearing body part 2, mounting plate 3, support 4, main shaft 5, backplate 6, impeller 7, spiral case 8, filter screen 9, parts of outlet pipe 10.Impeller 7 is screwed connection with main shaft 5, impeller 7 back blades and backplate 6 gaps guarantee by support 4 and main shaft 5 length tolerances, error leans against 3 times shimmings of mounting plate and adjusts, therefore assemble cumbersome, main shaft and support length dimension machining accuracy are difficult to guarantee, also are unfavorable for the interchangeability of product parts.Also having impeller neck screw thread end cylindrical and backplate is the clearance seal place, because the main shaft cantilever is long, be subject to its rigidity effects and the impact of spiral case Hydraulic Radial Force while being subject to moving, main shaft and impeller end neck inevitably have certain swing, with backplate, rub, denude impeller neck cylindrical and diminish due to for a long time friction and slurries, have a strong impact on impeller intensity, easily cause security incident.
Summary of the invention
The purpose of this utility model is to provide a kind of vertical slag slurry pump under liquid, solves above-mentioned problems of the prior art, and the first, the gap adjustment that solves in design back blade and backplate, reduce the length machining accuracy, improves the interchangeability of product parts; The second, solve in design impeller neck and backplate friction problem.
The purpose of this utility model is achieved through the following technical solutions: a kind of vertical slag slurry pump under liquid, comprise electric machine support, bearing body part, mounting plate, support, main shaft, backplate, impeller, spiral case, filter screen, parts of outlet pipe, the main shaft lower end adds anti-wear sleeve and two adjusting round nuts, the main shaft bottom is processed with screw thread step and one and coordinates step with anti-wear sleeve, anti-wear sleeve is little Spielpassung with coordinating of main shaft, and center of protecting panel's hole inner face is processed into the step-like of top protrusion.
Described anti-wear sleeve upper end is provided with the seam small stair, and an O RunddichtringO is housed in the seam small stair.
The utility model discloses a kind of vertical slag slurry pump under liquid new structure: on original old-fashioned traditional architecture basics; increased the round nut of an anti-wear sleeve and two adjusting use; change the shape and structure of backplate; make impeller neck and backplate clearance seal be changed to anti-wear sleeve and backplate clearance seal; thereby protection impeller neck is not rubbed; better protection impeller, improved impeller working life.Move anti-wear sleeve and adjust back blade and backplate gap by regulating two round nuts, fixing and locking impeller then, this structure is conducive to equipment adjustment and impeller demolition.Also reduce the accurate to dimension requirement, reduced cost of production, improved the versatility of product component.
The accompanying drawing explanation
The structural representation that Fig. 1 is the traditional vertical slag slurry pump under liquid.
The partial enlarged drawing that Fig. 2 is A place in Fig. 1.
The structural representation that Fig. 3 is vertical slag slurry pump under liquid of the present utility model.
The partial enlarged drawing that Fig. 4 is B place in Fig. 3.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 3, Figure 4, a kind of vertical slag slurry pump under liquid of the present utility model, comprise electric machine support 1, bearing body part 2, mounting plate 3, support 4, main shaft 5, backplate 6, impeller 7, spiral case 8, filter screen 9, parts of outlet pipe 10.Under the prerequisite that guarantees partially rigid under main shaft 5 liquid; change main shaft 5 lower end structures; be processed with screw thread step and one and coordinate step with anti-wear sleeve; install anti-wear sleeve 12 and two stainless steel round nuts 13 additional; anti-wear sleeve 12 is little Spielpassung with coordinating of main shaft 5; backplate 6 center hole inner faces are processed into the step-like of top protrusion; make impeller neck and backplate clearance seal be changed to anti-wear sleeve and backplate clearance seal; swing during impeller operation can not cause impeller neck and backplate to rub yet; thereby better protect impeller, improved impeller working life.Can move anti-wear sleeve and adjust back blade and backplate gap by regulating two round nuts at the window 11 of support 4.Be provided with the seam small stair in the upper end of anti-wear sleeve 12, an O RunddichtringO 14 is housed in the seam small stair, be used for sealing impurity and sewage and do not enter the impeller screw thread, guarantee that main shaft and anti-wear sleeve mating part and impeller screw thread can corrosions, be conducive to repair demolition.
Adopt the vertical slag slurry pump under liquid of the technical program, during assembling at first two round nuts be screwed into position at the bottom of the main shaft silk, after loading onto anti-wear sleeve, after impeller screws in the main shaft screw thread, measure and guarantee back blade and backplate gap with clearance gauge, then regulate round nut the locking of anti-wear sleeve lobulus parietalis superior wheel neck step, wherein second round nut tight, prevent from becoming flexible.
