Embodiment Construction

[0009] It can be seen from the drawings that this kind of steel-lined fluoroplastic alloy self-priming pump includes an impeller 4, a pump shaft 6, a rear cover 5 and a pump body. As a result, the suction chamber 1, the volute 2, and the extrusion chamber 3 are tightly connected with each other, and the extrusion chamber 3 is tightly connected with the rear cover 5. The surfaces of the suction chamber 1, the volute 2 and the extrusion chamber 3 are lined with a fluoroplastic structural layer 7, and the thickness of the fluoroplastic structural layer 7 is 4-6mm. The suction chamber 1, the volute 2, and the discharge chamber 3 are assembled after sintering and compression molding respectively, and can be connected and fixed with each other by fasteners such as bolts. Due to the steel-lined fluoroplastic structure of the pump, the volume of the liquid storage chamber (suction chamber, pressure discharge chamber) can be designed to be optimal under the premise of ensuring the stru...

Abstract

The self priming pump of fluoroplastic alloy lined steel for pumps mainly includes one impeller, one pump shaft, one back cover and one pump body. The pump body is assembled with one suction chamber, one volute, and one extruding chamber connected tightly. The assembled pump body has the suction chamber, the volute, and the extruding chamber molded and fluoroplastic lined separately, and thus has raised anticorrosion performance. At the same time, the assembled structure can also optimize the inside structure, and shorten the air-liquid separating time and the self priming time.

Description

technical field [0001] The invention relates to a pump, in particular to a steel-lined fluoroplastic alloy self-priming pump. Background technique [0002] Steel-lined fluoroplastic alloy self-priming pump is a single-stage internal mixing centrifugal self-priming pump, which has the advantages of high mechanical strength, strong corrosion resistance, and short self-priming time. It is mostly used in petrochemical, smelting, papermaking, medicine, Food processing and other industries. At present, due to the integral casting of the pump body structure of the same type of pump, the internal rubber lining is used for anti-corrosion treatment, the corrosion resistance (especially some strong corrosive media) is poor, and the inner rubber and steel body are also easy to peel off, thus affecting Use of self-priming pumps. In addition, the pump structure is integrally cast, the internal volume is affected, and the time for gas-liquid separation is long, so the self-priming time i...
