Abstract
The utility model relates to a graphite corrosion resisting submerged pump, which is mainly composed of a rotary part and a fixed part. A barrel body and a spitting body are pressed and combined together. A shaft sheath is directly arranged on a shaft. One end of an isolating sleeve is enchased in an annular trough of a rear pump cover, and the other end is enchased in an inner hole on the upper end of the barrel body. An impeller and an embedded part are pressed and combined into integration and are connected to the lower end of the shaft by threads. A suction body is connected with the barrel body by threads and tightly presses a guide blade and a front pump cover to the lower end of the rear pump cover. The utility model has the advantages of simple structure, simple production processes, low cost, small volume, convenient transport, and convenient use and maintenance. Because graphite has stable performance, the pump has strong adaptability, high reliability, and long service life.
Description
The utility model relates to the corrosion-resistant Under Water Pumps of a kind of graphite, is the chemical industry anti-corrosive pump.
Be used for carrying Under Water Pumps to be equipped with independent discharge pipe at present, place main pump body on one side with strongly corrosion liquid.Be that material is manufactured generally,, be difficult for transportation, maintenance because its pump housing volume is big with plastics, glass fibre reinforced plastics, stainless steel alloy or cast iron.Use also inconvenient.
It is strong, simple in structure that the purpose of this utility model provides a kind of corrosion resistance, and cost of production is low, uses, keeps in repair, transports all the corrosion-resistant Under Water Pumps of graphite easily.
Because of graphite is a kind of best resistant material, the main body part of the contact medium of pump all uses graphite to make.The utility model has structurally been cancelled independent discharge pipe, and spuing of liquid is to enter the passage that is made of cylindrical shell and separation sleeve via stator, rear pump cover, arrives outlet(discharge) flange and discharges.
The corrosion-resistant Under Water Pumps of this graphite, structure and production technology are simple, and cost is low.Also be suitable for standardization, seriation production in enormous quantities.This pump volume is little, transports, uses and keep in repair all to make things convenient for.Because of graphite high-and low-temperature resistance performance is good, wear-resisting, be difficult for wearing out again, easily processing, expansion coefficient is little, stable performance, so the adaptability of pump is strong, the reliability height.The inside and outside position that contacts with corrosive liquids of the pump housing all uses the good graphite of decay resistance to make, so its long service life.
Describe its technical solution in detail below in conjunction with embodiment's accompanying drawing.
Fig. 1 is the corrosion-resistant Under Water Pumps section of structure of graphite
As can be seen from the figure, the structure of the corrosion-resistant Under Water Pumps of graphite mainly is made up of rotating part and standing part.Cylindrical shell 6 presses together with the body 10 that spues, and sheath shaft 8 directly installs on the axle 9, and separation sleeve 7 one ends are bumped in the circular groove of rear pump cover 5, and the other end is bumped in the endoporus of cylindrical shell 6 upper ends.Impeller 3 is an one with embedded part 11 pressings, with the lower end that is threaded onto axle 9; Suction body 1 and cylindrical shell 6 are to be threaded and to compress stator 4 and front pump cover 2 lower end to rear pump cover 5; 12 is the bottom end bearing of axle 9.Spuing of liquid is to enter the passage that is made of cylindrical shell 6 and separation sleeve 7 through stator 4, rear pump cover 5, arrives outlet(discharge) flange 13 and discharges.
