Abstract
The utility model provides a chemical fluorine lining pump. The pump comprises a pump body, polythene composite layers and an impeller, wherein the high-molecular polythene composite layer materials are covered on the contact surfaces between media and the inner chamber of the pump body, between media and the impeller, between media and the pump cover and between media and one end of a shaft; the shaft and the impeller are in threaded connection with each other; and an anti-rotation sleeve is arranged at the top end of the shaft in a position connecting with the impeller. Due to the high-molecular polythene materials covered on the surface in contact with media of the inner chamber of the pump, the decay resistance of the pump is greatly improved; and the impeller and the shaft are in threaded connection with each other, and are fixed together not by a nut but by the anti-rotation sleeve arranged between the impeller and the shaft, so that the impeller can not rotate reversely when the shaft rotates, and the service life of the pump is prolonged.
Description
Technical field: the utility model relates to a kind of chemical industry lining fluorine pump.
Background technique: be extensive use of pump in industries such as pharmacy, oil, metallurgy, electric power, electrodeposits,, cause the corrosion of pump housing internal structure easily, so the working life of these pumps is not long because of corrosive liquids such as the highly basic of long-term delivery high concentration, strong acid.Perhaps need adopt very valuable metal to make, the expense costliness is that general enterprise holds and dares not accept.And being connected and all adopting nut to fix of the general impeller of old-fashioned pump and axle, when impeller ran up, set screw nut also can be followed motion together sometimes, because of there not being anti-reverse measure, causes impeller to come off easily, the damage pump body structure.
Summary of the invention: the purpose of this utility model will provide a kind of chemical industry lining fluorine pump exactly, and it can overcome the existing problem of above product well.The purpose of this utility model is to realize like this, chemical industry lining fluorine pump, be made up of the pump housing, polyethylene composite bed, impeller, it is characterized in that: the surface in that inner chamber, impeller, pump cover, the axle head of the pump housing contacts with medium all is coated with the high-molecular polythene composite material; Axle is set to scyewed joint with connecting of impeller, and in the top and the impeller joint of axle an anti-pivoted housing is set.The utility model is because in the inner chamber of pump, covered one deck high-molecular polythene material with the medium contacting point, the decay resistance of pump is greatly improved, impeller adopts scyewed joint with connecting of axle, do not use nut to fix on the top, but adopt between impeller and axle an anti-pivoted housing is set, thereby makes the impeller can transfer when moving, the working life of having improved pump.
Description of drawings:
Fig. 1 is a structural representation of the present utility model; 1. the pump housing, 2. polyethylene composite bed, 3. impeller, 4. pump cover, 5. anti-pivoted housing, 6. spool.
Embodiment: the utility model is described in further detail below in conjunction with accompanying drawing;
Chemical industry lining fluorine pump is made up of the pump housing 1, polyethylene composite bed 2, impeller 3, it is characterized in that: the surface in that inner chamber, impeller 3, pump cover 4,6 end of the pump housing 1 contact with medium all is coated with high-molecular polythene composite bed 2 materials; Axle 6 is set to scyewed joint with connecting of impeller 3, and in the top and impeller 3 joints of axle 6 an anti-pivoted housing 5 is set.During concrete enforcement, the fusing of high-molecular polythene composite material is annotated north on required pump housing inner chamber, impeller, pump cover, axle head and surface that medium contacts, coagulation forming, cooling, the demoulding get required part.Processing impeller tapped hole, tool withdrawal groove and keyway.At screw thread and the keyway that processing of axle left end and impeller match, the anti-pivoted housing of processing, and be provided with keyway.To prevent that pivoted housing puts into the impeller tool withdrawal groove, axle screws in the impeller, and the top is with anti-pivoted housing, tumbles in the key stationary positioned again.When under the drive of impeller at axle during high speed rotating, because of being provided with anti-pivoted housing and key, impeller can not come off, and only can revolve tighter and tighter.
