Description
A kind of clad lining pump is used for Chemical Manufacture and carries the device that contains acid, bases and solid particle medium liquid, belongs to mechanical pump class.
Pump is an indispensable device of undertaking the delivery technology medium in the production procedure of chemical fertilizer, chemical industry, metallurgy and mine industry.The opposite opened rubber lined pump of our factory (patent No. 89219316.6) pump housing and line with rubber are opposite opened, form by the preceding pump housing (2), the back pump housing (10), impeller (4), axle sleeve (7), axle (8), axle envelope parts (11), bracket portion (9), the pump housing and rubber lining is vertical centering control to be left, and the face that closes up that two double liners glue together to hold together the face and the front and back pump housing coincide on same plane.
The deficiencies in the prior art part is:
1, for processing medium with strong corrosion and abrasion, to preceding line with rubber and back line with rubber to close up face perishable, the face that closes up that two line with rubber of double close up the face and the pump housing coincide in one plane, because the corrosion that line with rubber closes up face, the corrosion that the pump housing closes up face before and after the influence, cause pump housing seepage, reduced the working life of pump.
2, the line with rubber in the pump housing is formed by compactings such as natural rubber, neoprenes, yet the performance that is limited to rubber, can only be applicable to the processing medium of a part, exist certain narrow limitation, for processing medium and have the processing medium that solid phase particles internally is lined with bump with strong corrosion, in phosphoric acid industry, phosphoric acid material pulp not only contains multiple composition acid solution, and contain solid particle, have strong corrosivity and abrasion, elastometric lining is unaffordable, if use reluctantly, then will frequently change elastometric lining.
The purpose of this utility model is to avoid above-mentioned the deficiencies in the prior art part and designs a kind of clad lining pump, changes inner lining structure, the shape of pump, improves the working life of pump, widens the using scope of pump.
The technical solution of the utility model is: a kind of clad lining pump, by the preceding pump housing (2), the back pump housing (10), impeller (4), axle sleeve (7), axle (8), axle envelope parts (11), bracket portion (9) is formed, it is characterized in that: be close to pump housing inboard, metal integral lining shell (3) is housed, whole lining shell (3) has the medium inlet, outlet is close to pump housing inlet (13) and pump housing outlet (14) inboard, metal liner lid (5) is equipped with on opposite in metal integral lining shell medium inlet, between metal integral lining shell (3) and the metal liner lid (5) seal ring (12) is housed.The diameter of metal liner lid (5) and metal integral lining shell (3) cooperation place is convenient to the installation of impeller than the big 2～6mm of impeller (4) external diameter.
Fig. 1 is clad lining pump structure figure, Fig. 2 is clad lining pump body structure figure, and by Fig. 1, shown in Figure 2, metal integral lining shell (3) does not have the slit in the preceding pump housing (2), the pump housing (10) engagement place, back, avoided the face that closes up of the front and back pump housings, processing medium can not leak into the pump housing and close up face.Adopt the kink lining technology, opposite in metal integral lining shell (3) medium inlet, metal liner lid (5) is housed, between metal integral lining shell (3) and the metal liner lid (5) seal ring (12) is arranged, the metal liner lid (5) that cooperates with metal integral lining shell (3) has a step, and axis of small circle is identical with the aperture of metal integral lining shell (3), than the big 2～6mm of impeller diameter, be convenient to impeller by dress, axis of great circle is convenient to seal washer (12) is compressed than the big 10～20mm of axis of small circle.Capsul spare (6) pushes against metal liner lid (5), and the front and back pump housing is still made the opposite opened combined structure, is convenient to installation, maintenance.
See by Fig. 2, inlet (13) and pump housing outlet (14) at the pump housing locate to make a fluted body step, metal integral lining shell inlet, exit face are lower than pump housing inlet, exit face 2～5mm, concave surface 2～3mm a little more than pump housing inlet, outlet, be convenient to like this between metal integral lining shell inlet, outlet and pump housing inlet, outlet, adorn packing ring (1), packing ring is generally used teflon, neoprene etc., packing ring exceeds pump housing inlet, exit face 2～5mm, thereby guarantees the good seal performance between pump and the external piece.
Fig. 3 is metal integral lining shell front view, Fig. 4 is metal integral lining shell-side view, in the runner of metal integral lining shell (3), vertical muscle (15) is arranged as can be seen from Figure 3, whole lining shell is divided into eight cross sections, since second cross section, is provided with vertical muscle (15) along runner, should narrow down gradually by vertical muscle, stop in the outlet port, the purpose that is provided with vertical muscle (15) is that the processing medium that contains solid phase can successfully be flowed out from outlet, prevents that solid-phase media from depositing in pump.
Characteristics of the present utility model are: the pump housing is opposite opened, and bulk metal pump case and metal liner lid are equipped with in pump housing inboard, and liner is a flush mounted type, and is movable detachable.
