Abstract
The utility model discloses a fluoroplastic alloy self-priming pump comprising a pump body (1), an impeller (2), a front pump cover (3), a pump cover (4) and a pump shaft (5), wherein the front pump cover (3) and the pump cover (4) are both connected with the pump body (1); the self-priming pump is characterized in that the horizontal height of a liquid inlet (6) at the front pump cover is above the external diameter of the impeller (2); the pump shaft (5) is connected with the impeller (2) through a connecting shaft (7); the surface of the connecting shaft (7) is provided with a fluoroplastic alloy layer (8); and the impeller (2) and the connecting shaft (7) are integrated. Due to the structure, the fluoroplastic alloy self-priming pump can realize life-long self-priming through one-draining, thus reducing labour intensity and improving work efficiency; the impeller and the connecting shaft are integrated, so that the torque force generated along with rotation can be ensured to be bore by a shaft root and the rear part of the impeller; and a soaking part of medium is a plastic alloy layer, so that corrosion is resisted and sealing effect is ensured.
Description
Technical field
The utility model relates to a kind of pump structure, especially relates to a kind of fluoroplastic alloy self-suction pump.
Background technique
Fluoroine-containing plastic alloy is to be formed according to certain ratio fusion by perfluoroethylene-propylene and teflon, is called for short fluorine alloy.By the goods that fluorine alloy is made, the relative perfluoroethylene-propylene intensity of its material is higher, and temperature tolerance also increases.Fluoride plastic alloy pump can any concentration of delivery temperature in-30 ℃～120 ℃ scopes severe corrosive such as strong acid, highly basic, strong oxidizer, organic solvent, the high-risk chemical mediator of poisonous, inflammable, explosive class, be specially adapted to industries such as chemical industry, oil, pharmacy, agricultural chemicals, plating, food.At present, domestic similar pump need be inhaled into the vacuum shape in use or need perfusion before each the use, and this has increased labor intensity greatly, has reduced efficiency.In addition, impeller root Sealing installation place has more influenced sealing effect owing to corroded by chemical mediator for a long time.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, drainage and the fluoroplastic alloy self-suction pump of self-priming throughout one's life.
The problem of the required solution of the utility model realizes by the following technical solutions: it comprises the pump housing, impeller, front pump cover, pump cover and pump shaft, front pump cover, pump cover all connect with the pump housing, the level height that it is characterized in that described front pump cover place liquid entering hole is on impeller outer diameter, pump shaft connects with impeller by connecing axle, connect a surface and be provided with the Fluoroine-containing plastic alloy layer, impeller with connect the axle be structure as a whole.
The pump housing described in the utility model, impeller adopt Fluoroine-containing plastic alloy to make.
The structure that the utility model adopts can realize a drainage and lifelong self-priming, has reduced labor intensity, has improved efficiency; Impeller is structure as a whole with connecing axle, can guarantee the torque force a when root and impeller rear portion are born with rotation, and medium soaks part for the plastic alloy layer, and is corrosion-resistant, guarantees sealing effect.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further:
Accompanying drawing is depicted as structural representation of the present utility model
Among the figure 1, the pump housing 2, impeller 3, front pump cover 4, pump cover 5, pump shaft 6, liquid entering hole 7, connect axle 8, Fluoroine-containing plastic alloy layer
Embodiment
By accompanying drawing as can be known, this fluoroplastic alloy self-suction pump comprises the pump housing 1, impeller 2, front pump cover 3, pump cover 4 and pump shaft 5, front pump cover 3, pump cover 4 all connect with the pump housing 1, the level height that it is characterized in that described front pump cover place liquid entering hole 6 is on impeller 2 external diameters, pump shaft 5 connects with impeller 2 by connecing axle 7, connect axle 7 surfaces and be provided with Fluoroine-containing plastic alloy layer 8, impeller 2 with connect axle 7 and be structure as a whole.Connect axle for the mold pressing of high-quality aluminium processing back outsourcing plastic alloy forms, make impeller and metal connect axle and become one securely.The pump housing described in the utility model, impeller adopt Fluoroine-containing plastic alloy to make.The utility model mechanical seal is adopted without the adjustable end face seal technology of cooling water, is made by materials such as silicon carbide, high-purity alpha-alumina pottery, filling tetrafluoro, graphite.
Obviously, the foregoing description of the present utility model only is for the utility model example clearly is described, and is not to be qualification to mode of execution of the present utility model.For those of ordinary skill in the field, can also make other multi-form variation or changes on the basis of the above description.Here need not also can't give all mode of executions exhaustive, and these belong to conspicuous variation or the change that spirit of the present utility model draws and still are among the protection domain of the present utility model.
Claims (2)
1. fluoroplastic alloy self-suction pump, comprise the pump housing, impeller, front pump cover, pump cover and pump shaft, front pump cover, pump cover all connect with the pump housing, the level height that it is characterized in that described front pump cover place liquid entering hole is on impeller outer diameter, pump shaft connects with impeller by connecing axle, connect a surface and be provided with the Fluoroine-containing plastic alloy layer, impeller with connect the axle be structure as a whole.
2. a kind of fluoroplastic alloy self-suction pump according to claim 1 is characterized in that the described pump housing, impeller adopt Fluoroine-containing plastic alloy to make.
