Description
Technical field
The utility model relates to industrial pump field, particularly relates to a kind of intelligent type energy saving material-saving Petrochemical process stamping pump.
Background technique
Pump is widely used in conveying liquid body medium in the production procedure of the enterprises such as oil, chemical industry, pharmacy, printing and dyeing, plating, food, environmental protection.Existing pump bearing is arranged in bracket hole, there is tolerance due to during each Element Design, and after pump assembling, axial integrating error are large, cause the gap between impeller and pump case not meet size requirement.Current installation method joins work according to actual conditions, makes gap control between impeller and pump case within the scope of given size, but this method is time-consuming, effort.And during work, electric machine rotation drives pump shaft and impeller to rotate together, can wear and tear in long-term running, the gap between impeller and pump case be strengthened, causes volumetric loss to strengthen, pump efficiency reduces, in addition in the process manufacturing pump and installation, the axial error produced cannot adjust, and wearing and tearing can make the axial error of pump strengthen, cause shorten the working life of pump, even cause pump to scrap.
Summary of the invention
The purpose of this utility model is to provide a kind of intelligent type energy saving material-saving Petrochemical process stamping pump, this pump structure rationally, the adjustment of pump shaft axial clearance can be carried out, the working life of pump can be extended, improve the efficiency of pump, reduce user cost.
The utility model is achieved in that intelligent type energy saving material-saving Petrochemical process stamping pump, comprise pump case, axle, pump cover, bracket, axle is provided with impeller, mechanical seal, bearing, it is characterized in that: in described bracket hole, be provided with solid housing, the hole back-up ring of rear bearing and fixing rear bearing is provided with in solid bearing base rear end hole, fore bearing is provided with in front aperture, front-end face is provided with fore bearing gland, the end flanges of fore bearing gland and solid housing is fixed by screws in bracket front-end face, the end flanges of solid housing is also evenly equipped with three adjusting screw, solid bearing base rear end is provided with rear bearing cover, and rear bearing cover is fixed by screws on bracket, seal ring is provided with between described solid housing and bracket.
Control interval is provided with between described solid housing and rear bearing cover.
Control interval is provided with between the end flanges of described solid housing and bracket.
Described solid housing cylindrical is provided with oil inlet hole and oil outlet.
Groove is provided with between described solid housing and bracket.
The utility model is rational in infrastructure, can carry out the adjustment of pump shaft axial clearance, extends the working life of pump, improves the efficiency of pump, reduce user cost.
Accompanying drawing explanation

Embodiment
Below in conjunction with accompanying drawing, the utility model is further described:
With reference to accompanying drawing, intelligent type energy saving material-saving Petrochemical process stamping pump, comprise pump case 1, axle 14, pump cover 3, bracket 15, axle 14 is provided with impeller 2, mechanical seal 17, bearing, it is characterized in that: in described bracket 1 hole, be provided with solid housing 8, the hole back-up ring 5 of rear bearing 6 and fixing rear bearing is provided with in stomidium after solid housing 8, fore bearing 10 is provided with in front aperture, front-end face is provided with fore bearing gland 11, fore bearing gland 11 is fixed on bracket 15 front-end face with the end flanges of solid housing 8 by screw 13, the end flanges of solid housing 8 is also evenly equipped with three adjusting screw 12, solid housing 8 rear end is provided with rear bearing cover 4, and rear bearing cover 4 is fixed by screws on bracket 15, seal ring 9 is provided with between described solid housing 8 and bracket 15.Control interval is provided with between described solid housing 8 and rear bearing cover 4.Control interval is provided with between the end flanges of described solid housing 8 and bracket 15.Described solid housing 8 cylindrical is provided with oil inlet hole and oil outlet.Groove is provided with between described solid housing 8 and bracket 15.
During concrete enforcement, in the utility model, impeller, pump case adopt stainless steel material punch welding to make, than casting pump, weight is equivalent to 1/3 of similar casting pump, and efficiency is higher than similar pump by 6 ~ 8%, cost is equivalent to 2/3 of similar pump, energy-conservation, material-saving, manufacturing efficiency is high, avoid environmental pollution, reduce labor intensity; Corrosion-resistant, the life-span is long; The space that impact briquetting pump impeller moves in pump case is large more than casting pump, has both ensured the design performance parameter of pump, and has ensured again efficiency and the corrosion resistance of pump; Pump case is the housing of uneven, an asymmetric scroll casing shape, and at Multi-step forming, stretch, bending, swollen type process, for preventing stainless steel embrittlement, having carried out solution treated, having ensure that quality; Sealing surface gap between impeller eye, casing inlet is less than 0.5mm, and craft precision is high, and gap is easy to adjust.Set up solid housing and can not dismantle the pump housing by adjusting screw adjusting vane with the gap between the pump housing, maintenance pump Effec-tive Function always.In installation process, when the gap between impeller and pump case is undesirable, need to adjust interval; In the course of the work, when the gap between impeller and pump case can be made again after damage in impeller to strengthen, cause volumetric loss to strengthen, when pump efficiency reduces, need to adjust interval; Regulating method is: unclamp screw 13, then adjust adjusting screw, and solid housing band moving axis is moved axially, and adjusting play makes impeller and the gap between pump case and pump cover adjust in predetermined range, and then tightens screw 13.
