Abstract
The invention discloses a pump. The pump comprises a pump body, a pump cover arranged on one side of the pump body, a shaft for driving, a bearing frame and bearings for supporting the shaft and mounting supporting feet for supporting the bearing frame. The pump is characterized in that the pump body is a double-volute pump body; an open impeller is arranged at one end of the shaft in the pump body; pump body wear rings are arranged between the open impeller and the pump body and between the open impeller and the pump cover respectively; the bearing frame is an integrated heavy bearing frame; the bearing is a lubricating ball bearing. The pump is simple in structure and convenient to maintain.
Description
Technical field
The present invention relates to a kind of pump.
Background technique
Existing petro-chemical pump comprises the parts such as the pump housing, pump cover, pump shaft, motor and base, pump shaft is through the pump housing and pump cover, in the pump housing, pump shaft one end is equiped with impeller, and driven by motor pump shaft rotates, and has mechanical seal and packing seal two kinds according to use medium axle head.Be generally used for the liquid of the conveyings such as oil refinery, petrochemical industry, coal processing industry, paper-making industry, sugar industry containing particle due to petro-chemical pump, therefore adopt unshrouded impeller wearing and tearing few, energy consumption is low, long service life, is easy to cleaning, is convenient to maintenance.Therefore, be necessary to design a kind of novel petro-chemical pump, to overcome above-mentioned defect.
Summary of the invention
For solving above-mentioned existing shortcoming, main purpose of the present invention is the pump providing a kind of practicality, and structure is simple, be convenient to maintenance.
For reaching above-described object, following technological scheme taked by a kind of pump of the present invention:
A kind of pump, comprise the pump housing, be contained in the pump cover of pump housing side, the axle for transmission, the bearing bracket stand supporting described axle and bearing and the installation leg for supporting described bearing bracket stand, it is characterized in that, the described pump housing is two misfortune shell pump housings, in the pump housing, one end of described axle is equiped with unshrouded impeller, be respectively equipped with pump housing wear ring between described unshrouded impeller and the described pump housing and pump cover, described bearing bracket stand is overall heavy bearing frame, and described bearing is lubricating ball bearings.
Adopt the present invention of as above technological scheme, there is following beneficial effect:
1, unshrouded impeller easy-maintaining and cleaning is adopted.
2, between unshrouded impeller and the described pump housing and pump cover, be respectively equipped with pump housing wear ring, easy accessibility, be easy to change.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is unshrouded impeller structural representation of the present invention.
Embodiment
In order to further illustrate the present invention, be described further below in conjunction with accompanying drawing:
As depicted in figs. 1 and 2, a kind of pump of the present invention, comprising the pump housing 102 and being contained in is the pump cover 151 of body side, the pump housing 102 is two misfortune shell fruit bodies, and caliber is large, and corrosion allowance is large, radial force is little, and axle degree of drawing is little, and velocity in pipes is little, vibrate little, noise is low, and the pump housing 102 is with automatic exhaust device, pipeline configuration is simple, and bearing capacity is good, and the pump housing 102 need not support, can not rupture, the life-span is long.Pump cover 151 is provided with overall heavy bearing frame 330 away from the pump housing 102 side.Bearing bracket stand 330 adopts integrated type, and coaxality is good, stability is high, good rigidly, amount of deflection are little.One end in the middle part of bearing bracket stand 330 and away from the pump housing 102 is respectively equipped with bearing cap 360, is respectively equipped with anti-friction bearing 320 inside two bearings lid 360, and anti-friction bearing 320 is lubricating ball bearings in the present embodiment, can self oiling.One to be arranged on bearing bracket stand 330 between two bearings 320 in order to the axle 21 of transmission, and one end of axle 21 is passed described pump cover 151 and is entered in fruit body 102, fruit body 102 axis 21 being equiped with a unshrouded impeller 230, being also provided with the impeller nut 922 for locating unshrouded impeller 230 near the shaft end being body 102 side.Pump housing wear ring 502 is respectively equipped with between pump cover 151.This pump housing wear ring 502 Ke Yi Red washes, and can also change after wearing and tearing, saves maintenance and spare part expense, keeps in repair simple, convenient and rapid.Be provided with axle sleeve 524 at axle 21 near unshrouded impeller 230 place, outside bearing bracket stand side, be provided with sealing cover 471 at the external pump cover 151 of axle sleeve.The liquid-discharging tube 710 for discharge opeing is provided with at the lower curtate of bearing bracket stand 330 near pump cover 151 place.The installation leg 183 for back shaft bolster 330 is connected with away from the lower curtate of pump cover 151-side at bearing bracket stand 330.
The parameter that the present invention uses is as follows: bore 25-400mm, and flow (Q) can reach 2600m3/h, and working pressure (P) can reach 2.5Mpa, and operating temperature (T) is between negative 20 degree to positive 450 degree.
