Abstract
The utility model provides a petrochemical pump, comprising a pump body, a pump cover arranged on one side of the pump body, a shaft for driving, a bearing frame and a bearing which are used for supporting the shaft, and installation pins for supporting the bearing frame, wherein one end of the shaft in the pump body is provided with an open impeller, a pump body wear ring is respectively arrangedamong the open impeller, the pump body and the pump cover. Adopting the open impeller, the petrochemical pump can be easy to repair and clean.
Description
[technical field]
The utility model relates to a kind of pump, particularly a kind of petrochemical industry pump.
[background technique]
Existing petrochemical industry pump comprises parts such as the pump housing, pump cover, pump shaft, motor and base, pump shaft passes the pump housing and pump cover, pump shaft one end is equiped with impeller in the pump housing, and the driven by motor pump shaft rotates, and according to the working medium axle head two kinds of mechanical seal and packing seals is arranged.Because the petrochemical industry pump generally is used for the liquid that conveyings such as oil refinery, petrochemical industry industry, coal processing industry, paper-making industry, sugar industry contain particle, therefore adopt the unshrouded impeller wearing and tearing few, energy consumption is low, and long service life is easy to clean, and is convenient to maintenance.
Therefore, be necessary to design a kind of novel petrochemical industry pump, to overcome above-mentioned defective.
[model utility content]
The purpose of this utility model provides a kind of simple in structure, petrochemical industry pump of being convenient to keep in repair.
The utility model petrochemical industry pump, comprise the pump housing, be contained in the pump housing one side pump cover, be used for transmission axle, support described axle bearing bracket stand and bearing, be used to support the installation leg of described bearing bracket stand, an end of described axle is equiped with unshrouded impeller in the pump housing, is respectively equipped with pump housing wear ring between described unshrouded impeller and the described pump housing and pump cover.
Wherein, the described pump housing is the double volute pump housing.
Wherein, described bearing bracket stand is whole heavy bearing frame.
Wherein, described bearing is lubricated ball bearing.
Because adopt said structure, the petrochemical industry pump of the utility model has following beneficial effect:
1. owing to adopt unshrouded impeller easy-maintaining and cleaning.
2. owing to be respectively equipped with pump housing wear ring between unshrouded impeller and the described pump housing and pump cover, easy accessibility is easy to change.
[description of drawings]
Fig. 1 is the utility model petrochemical industry pump structure schematic representation.
Fig. 2 is the utility model petrochemical industry pump unshrouded impeller structural drawing.
[embodiment]
Below in conjunction with drawings and Examples the utility model petrochemical industry pump is further described.
As shown in Figure 1, the utility model petrochemical industry pump comprises the pump housing 102 and is contained in the pump cover 151 of the pump housing one side that the described pump housing 102 is the double volute pump housing, caliber is big, and corrosion allowance is big, and radial force is little, shaft deflection is little, and velocity in pipes is little, vibrates little, noise is low, and the pump housing has automatic exhaust device, and pipeline configuration is simple, bearing capacity is good, the pump housing need not support, can not rupture, and the life-span is long.Described pump cover 151 is provided with whole heavy bearing frame 330 away from the pump housing one side.Bearing bracket stand 330 adopts that the integrated type coaxalitys are good, stability height, good rigidly, amount of deflection are little.The end that described bearing bracket stand 330 middle parts reach away from the pump housing is respectively equipped with bearing cap 360, and two bearings lid inboard is respectively equipped with anti-friction bearing 320, and anti-friction bearing 320 is lubricated ball bearing in the present embodiment, but self oiling.One axle 21 in order to transmission is arranged on the described bearing bracket stand 330 320 of two bearings, and an end of described axle 21 passes described pump cover 151 and enters in the pump housing 102, be equiped with a unshrouded impeller 230 on the axle 21 described in the pump housing 102, also be provided with the impeller nut 922 that is used to locate described unshrouded impeller 230 at shaft end near the described pump housing 102 1 sides.151 of pump covers are respectively equipped with pump housing wear ring 502.This pump housing wear ring 502 can wash, and can also change after the wearing and tearing, saves maintenance and spare part expense, keeps in repair simple, convenient and rapid.Be provided with axle sleeve 524 at described axle 21 near unshrouded impeller 230 places, be provided with sealing cover 471 near outside bearing bracket stand one side at the external pump cover 151 of axle sleeve.Lower curtate at bearing bracket stand 330 close described pump cover 151 places is provided with the liquid-discharging tube 710 that is used for discharge opeing.Be connected with the installation leg 183 that is used to support described bearing bracket stand 330 at bearing bracket stand 330 away from the lower curtate of described pump cover 151 1 sides.
The parameter that the utility model petrochemical industry pump uses is as follows: bore 25-400mm, flow (Q) can reach 2600m
3/ h, working pressure (P) can reach 2.5Mpa, and operating temperature (T) is between-20 ℃～+ 450 ℃.
