The utility model is characterized in that a ceramic corrosion preventive cap is installed at the end where a main shaft is connected with the impeller, the outer surface of a T-shaped clamping platform of the main shaft is tightly sheathed with a ceramic shaft sleeve, and a sealing assembly is tightly sheathed on the ceramic shaft sleeve out of the pump body and is fixed on the pump body by bolts. The utility model has the advantages of simple and compact structure, easy processing, convenient maintenance, corrosion resistance, and long service life.
Description
The utility model belongs to the single suction single stage centrifugal pump, specifically is a kind of wear-resistance and anti-corrosion ceramicpump.
Present oil, pharmacy, brewage and mostly the employed corrosion protection pump of industry such as beverage is to adopt stainless steel to make, and black box is installed in the pump housing, this pump can be used in weak corrupt liquid normally, and effect preferably arranged, but when stainless steel pump uses in the severe corrosive fluid, because of stainless steel is a metal material, lose using value so be easy to be corroded, particularly at food, industries such as beverage, in a single day the stainless steel pump housing loses anti-corrosive properties, will be to food, the quality of beverage produces very big harmful effect, thereby influence the healthy of people, and the pump housing of stainless steel is subjected to the influence of technology, the processing cost height, be subjected to the influence of configuration aspects, black box is subjected to easily aging being out of order of immersion of liquid for a long time in the pump housing, and maintenance needs the pump housing is all dismantled, so safeguard also very inconvenient, at the problems referred to above, people just are easy to processing in active research, user cost is low, the ceramic-like pump of highly corrosion resistant, though existing ceramic-like pump on the existing market, but its structure is identical with former general service pump, and because of black box is installed in the pump housing, friction-produced high temperature when pump work, one device to the black box cooling must be set, so still there has been above-mentioned deficiency.
The purpose of this utility model be to provide a kind of simple and compact for structure, be easy to processing, highly corrosion resistant, applied range, be convenient to safeguard the wear-resistance and anti-corrosion ceramicpump of long service life.
The utility model is achieved through the following technical solutions:
It is a kind of wear-resistance and anti-corrosion ceramicpump, comprise the pump housing, impeller and Sealing, the pump housing is made up of end cap and pump case, and in end cap and pump case respectively by being mixed with the anticorrosion mortar suit ceramic cap and the pump case of binder, spindle nose in the pump housing is installed ceramic impeller by woodruff key, main shaft is connected with motor by coupling, it is characterized in that the end that main shaft is connected with impeller installs ceramic anticorrosion cap, the spindle set bearing that the pump housing is outer, and be one with supporting base fixed installation, at the suit Ceramic shaft sleeve of the T of main shaft shape card platform intimate, and tight suit black box on the Ceramic shaft sleeve outside the pump housing, black box is fixed by bolts on the pump housing.
Adopt between described ceramic impeller and Ceramic shaft sleeve, the pump housing and the black box on poly-tetrafluoro rubber and the axle sleeve and distinguish suit seal ring closely.
Described black box is made up of an above seal ring that is arranged in order, seal ring by fixed by nut in cartridge.
It is the structure of M shape that seal ring in the described black box adopts poly-tetrafluoro rubber ring and section.
The back side of described ceramic impeller is symmetrily processed with blade.
The water outlet of described pump is Archimedian screw parabolic shape structure in a side of the pump housing.
Be symmetrily processed with fixing threaded hole on the end cap face of the water inlet oral area of described pump.
The utility model compared with prior art, black box is in the pump housing when having changed traditional wheel rotation, be subjected to easily aging being out of order of immersion of corrosive liquids for a long time, and during wheel rotation and black box friction-produced high temperature, must establish the deficiency of cooling device more in addition, black box has been installed on the outer Ceramic shaft sleeve of the pump housing, and ceramic anticorrosion cap has been installed at the fixing spindle nose of impeller, each seal point has adopted multi-stage sealed mode, so have the following advantages:
1, simple and compact for structure, be easy to processing, be convenient to safeguard.
2, highly corrosion resistant, applied range, long service life.
Describe in further detail below in conjunction with accompanying drawing:
Fig. 1: the utility model example structure schematic representation.
Among the figure: 1 end cap, 2 anticorrosion ceramic end caps, 3 pump cases, 4 anticorrosion ceramic pump cases, 5 ceramic impellers, 6 Ceramic shaft sleeves, 7 ceramic impeller caps, 8 Spindle nuts, 9 main shafts, 10 black boies, 11,12,13 seal washers, 14 mortars
As shown in Figure 1, the same with other pump in use, the import and the outlet of pump are connected with pipeline respectively, and main shaft 9 connected with motor by coupling, can use with same mode of operation by similar pump with other, because of direct symmetry on the inlet end cap 1 of this pump has been processed fixing threaded hole, saved traditional flange-type connecting head, so can make the processing of end cap 1 more easy, structure is also simpler, and outlet is in a side of pump case 3, and throwing face is spiral of Archimedes formula structure, throw away along parabolic shape when liquid is thrown away by the rotation of ceramic impeller 5, effectively raise lift; In addition on the main shaft 9 suit Ceramic shaft sleeve 6, and on the Ceramic shaft sleeve 6 of pump housing outside closely suit black box 10, between impeller 5 and the Ceramic shaft sleeve 6 suit poly-polytetrafluoroethylsealed sealed circle 13, because pump has adopted multi-stage sealed mode, thereby ceramic impeller 5 liquid that can not when rotating is leaked to outside the pump housing because of sealing problem, black box 10 has been installed on the Ceramic shaft sleeve 6 of outside of the pump housing, also solved and be subjected to corrosive liquids to soak easily aging phenomenon for a long time, ceramic component and poly-tetrafluoro rubber are all high temperature resistant, can stand long-term operation friction, no longer need special cooling medium cooling, made things convenient for maintenance; Because of pump uses in corrosive atmosphere for a long time; so end cap 1 at pump; corrosion protection pottery end cap 2 and corrosion protection pottery pump case 4 have been set with in the pump case 3; the hold-doun nut 8 outside suits of impeller 5 and main shaft 9 ceramic impeller cap 7; make the position that contacts with liquid in the pump housing all use ceramic component; played good antiseptic effect; the negative blade at pottery impeller 6 backs is when wheel rotation; the liquid at impeller 6 back sides can be thrown away; promptly reduced the negative pressure between the impeller 6 and the pump housing; reduce the pressure of axle envelope; make seal ring and black box 10 sealing effects better again; end cap 1 at pump; adopt the mortar cast to be adhesively fixed between the corrosion protection of setting-in pottery end cap 2 and the corrosion protection pottery pump case 4 respectively in the pump case 3; both the ceramic component in the pump housing had been played fixedly protective action; played damping again; reduce the effect of noise; and Ceramic shaft sleeve 6 can according to pump case 3 length suitably extend; so at one end during serious wear; the other end can be inverted install and continue to use, greatly reduce user cost.
This pump is when being applied to food, beverage industries, because the easy-formation of pottery processing, sanitation and hygiene, highly corrosion resistant, can not pollute food, beverage, and cost is about 1/2 of stainless steel pump, so can be used as the update product of stainless steel pump, in addition because ceramic distinctive high-corrosion resistant, high temperature resistant can be widely used in every profession and trades such as medicine, chemical industry, oil equally.
