Abstract
The utility model provides a U-shaped full sealing anticorrosion pump, comprising a pump body, bearings, rolling wheels, a wheel carrier and a union joint. The utility model is characterized in that a U-shaped pipeline diaphragm which has a pipeline inner chamber is arranged in the pump body, and the U-shaped pipeline is fixed on the pump body by the self projection. During the utility model works, the shape of the U-shaped pipeline diaphragm gets smaller, the pulling stress is small, so the service life is long. Because the liquids does not contact with the pump body, the pump body can be made of metallic material, the pump with a high flow rate can be made, and the use range of users can be enlarged.
Description
The utility model belongs to whole-sealed corrosion-resistant pump, is the improvement to existing whole-sealed corrosion-resistant pump.
The corrosion free pump of existing conveying strong acid, alkali lye body, though come out for many years, but still exist several shortcomings: one, the most outstanding shortcoming be exactly diaphragm of rubber deformation is excessive in the course of the work, the distortion pulling force is big, cause diaphragm of rubber to be easy to break, mean lifetime has 100 hours approximately; Two, because the pump housing and diaphragm of rubber are formed transfusing chamber jointly, thereby the pump housing must adopt engineering plastics to make, and it is bigger that the pump housing is subjected to that process limitation can not make, so the corrosion free pump of this kind structure can not be made the corrosion free pump of big flow, using scope is restricted; In case three diaphragm of rubber break, liquid spill can only overflow from the door hole, and leakage can not be reclaimed, and causes wave useless.
The purpose of this utility model is in order to solve above-mentioned existing problems, a kind of U type whole-sealed corrosion-resistant pump to be provided.It can improve the working life of diaphragm of rubber, produces the corrosion free pump of big flow, and leakage is reclaimed.
In order to achieve the above object, the utility model comprises pump seat, the pump housing, liquid inlet and outlet, bearing, wheel carrier, roller, union joint, it is characterized in that being equipped with in the pump housing one and have inner cavity of pipe it is shaped as the U-shaped pipeline barrier film of " U " shape, its relies on the projection of its periphery to be installed in the pump housing inner chamber corresponding grooves.
For the deformation with U-shaped pipeline barrier film reduces to minimum, its shape of cross section can be an ellipticity.
In order to carry liquid such as strong acid, highly basic, the inwall of U-shaped pipeline barrier film is brushed the corrosion resistant barrier film inwall of one deck (as teflon, polyethylene); In order to strengthen the anti-crushing strength of U-shaped pipeline barrier film, its rubber substrate internal layer is filled with reinforced layer (as cord fabric, nylon fiber).
In order to reclaim leakage, liquid return pipe is arranged at pump housing bottom.
During work, liquid enters inner cavity of pipe from liquid entering hole, under the extruding of roller, U-shaped pipeline barrier film inwall is overlayed on the inner face of its outer wall, thereby liquid is pumped into liquid outlet.Owing to the U-shaped that is shaped as of U-shaped pipeline barrier film, and its cross section is an ellipticity, thereby in extrusion process, its deformation is corresponding less, thereby tensile stress is little, has improved its working life.Also because liquid passes in and out from inner cavity of pipe, so that the pump housing need not is corrosion-resistant, just the pump housing needn't adopt engineering plastics to make, and can adopt cast iron to make, and this has just overcome the existing corrosion free pump pump housing and has been subjected to process limitation can not make the shortcoming of big flow.In case if U-shaped pipeline membrane ruptures, leakage can be flowed out from liquid return pipe and be reclaimed, and has avoided waste.
Below in conjunction with accompanying drawing the utility model is described in detail.
Fig. 1 is that master of the present utility model looks half-sectional view.
Fig. 2 is that part sectioned view is looked on the right side of the present utility model.
Fig. 3 is that the master of U-shaped pipeline barrier film looks half-sectional view.
Fig. 4 is the plan view of U-shaped pipeline barrier film.
Fig. 3 is the A-A sectional drawing of U-shaped pipeline barrier film.
Fig. 6 is the partial enlarged drawing of projection.
1 pump seat; 2 liquid return pipes; 3 projections; 4U type pipeline barrier film; 5 pump housings; 6 rollers; 7 wheel carriers; 8 bearings; 9 bearing caps; 10 liquid outlets; 11 liquid entering holes; 12 belt pulleys; 13 union joints; 14 motors; 15 inner cavity of pipe; 16 barrier film inwalls; 17 reinforced layers; 18 rubber substrates.
Referring to above-mentioned accompanying drawing, the pump housing 5 adopts cast iron to make, it is to be integral by two mutual spiral-locks of housing, liquid inlet and outlet 11,10 is arranged on its pump housing 5, there is liquid return pipe 2 its bottom surface, and bearing 8 is housed in the pump housing 5, and three rollers 6 are housed on the wheel carrier 7, the end of wheel carrier 7 is equipped with union joint 13, and it and motor 14 link.The one U-shaped pipeline barrier film 4 with inner cavity of pipe 15 is housed in the pump housing 5, its shape resembles " U " shape, for it is fixed on the pump housing 5, its periphery has a circle projection 3, projection 3 can spiral-lock make U-shaped pipeline barrier film 4 fixing in the pump housing 5 corresponding grooves like this, in roller 6 extrusion processes, reduces the deformation of U-shaped pipeline barrier film 4, be beneficial to improve working life, the shape of cross section of U-shaped pipeline barrier film 4 is an ellipticity.Referring to Fig. 6, the tube wall of U-shaped pipeline barrier film 4 constitutes: brush one deck teflon on rubber substrate 18 surfaces, the barrier film inwall 16 of material, its rubber substrate 18 inner reinforced layer 17(such as cord fabric, nylon fibers of filling).
During work, liquid is from liquid entering hole 11 flow ipe inner chambers 15, under the extruding of roller 6, U-shaped pipeline barrier film 4 inwalls are extruded deformation, ride on the inner face of U-shaped pipeline barrier film 4 outer walls, so just can form to hold and become, liquid is drawn into a discharge, the utility model is owing to changed the structure of existing diaphragm of rubber, it is little to make it produce deformation, and tensile stress reduces, and has reached to improve the diaphragm of rubber purpose in working life, pass in and out the inner cavity of pipe 15 of liquid in shape pipeline barrier film 4 in addition and do not contact with the pump housing 5, make the material of the pump housing 5 can select metallic material for use, thereby can make the corrosion free pump of big flow, enlarged using scope, leakage can be reclaimed through liquid return pipe 2, has avoided the loss of liquid.
