Detailed Description
In order to better understand the technical scheme, the technical scheme is described in detail in the following with reference to the attached drawings of the specification and specific embodiments.
A self-priming pump with an open-door movable flange 19, comprising: pump body 7, pump body 7 in be provided with pump shaft 12, pump shaft 12 be connected with motor 1 through electricity federation 16, motor 1 pass through the bolt fastening on motor frame 3, motor frame 3 be connected with pump body 7 through the bolt, pump body 7 upside be provided with seal box 5, seal box 5 in be provided with vice impeller 14, vice impeller 14 set up on pump shaft 12 and piece together cap 13 fixed through vice impeller, pump shaft 12 lower extreme be fixed with impeller 11, pump body 7 on be provided with drain plug 9, pump body 7 left side welding have drain pipe 15, the right side welding has feed liquor pipe 8, the one end of drain pipe 15 be fixed with non return valve body 17 through flange cooperation bolted connection, non return valve body 17 in be provided with valve rod 18, non return valve body 17 and drain pipe 15 hookup location department be provided with movable flange 19, movable flange 19 one side pass through flange connection on pivot 20 and the drain pipe 15 and fix. The movable flange 19 is matched with the valve rod 18, and the movable flange 19 is reset to form sealing with the liquid outlet pipe 15.
The liquid inlet pipe 8 is positioned between the auxiliary impeller 14 and the impeller 11, the liquid outlet pipe 15 is positioned at the lower side of the impeller 11, the liquid inlet of the liquid inlet pipe 8 faces upwards, the liquid outlet of the liquid outlet pipe 15 faces rightwards, and the liquid outlet pipe 15 is communicated with an explosion-proof controller. 5 upside of seal box be provided with the lug, lug embedding motor frame 3 in, seal box 5 passes through the bolt and fixes with motor frame 3.
