Embodiment Construction
[0023] The present invention will be further described below in conjunction with the drawings.
[0024] Such as Figure 1-4 As shown in the figure, a corrosion-resistant and wear-resistant slurry pump with an anti-loose impeller includes a front cover 2, a pump body 1, a pump shaft 5, an impeller 3, a rear cover 4, a connecting frame 7, a suspension body assembly 8, The cartridge mechanical seal 6, the impeller 1 is a semi-open impeller, and includes an impeller cover 32. The center of the impeller cover 32 is close to the front cover 2 with a protrusion 34, and the protrusion 34 is surrounded by There is a wheel 31, the wheel 31 includes a main wheel 311 and a secondary wheel 312, the main wheel 311 extends from the bottom of the protrusion 34 to the edge of the impeller cover 32, the secondary wheel 312 is located on the main wheel 311 In between, the protrusion 34 extends to the edge of the impeller cover 32 at a certain distance from the bottom of the protrusion 34. The prot...

The invention belongs to the technical field of wear-resistant and corrosion-resistant slurry pumps, in particular to a corrosion-resistant and abrasion-resistant slurry pump containing an anti-looseimpeller. The corrosion-resistant and abrasion-resistant slurry pump comprises a front cover, a pump body, a pump shaft, the impeller, a rear cover, a connecting frame, a suspension assembly and a collection type mechanical seal, wherein the impeller is a semi-open impeller, and comprises an impeller cover, a bulge is arranged on one side of the impeller cover, and wheel pieces are arranged on theperiphery of the bulge; and each wheel piece comprises a main wheel piece and an auxiliary wheel piece, a hollow groove penetrating through the pump shaft is formed in the pump shaft, a pull rod is arranged in the hollow groove, an outer thread matched with an inner thread is arranged on the periphery of one side, close to the impeller, of the pull rod, and one end, away from the impeller, of thepull rod is fixed with a nut. Compared with the prior art, the method has the advantages that the impeller and the pump shaft are relatively fixed through the pull rod, and meanwhile, the sealing area can be reduced, the impeller can be effectively prevented from being reversely rotated due to the slurry pump, and the problem that the slurry pump or the impeller is loosened due to the fact that liquid flows backwards at the liquid outlet of the slurry pump is solved.
Description
Technical field [0001] The invention belongs to the technical field of wear-resistant and corrosion-resistant slurry pumps, and particularly relates to a corrosion-resistant and wear-resistant slurry pump containing an anti-loose impeller. Background technique [0002] Slurry pump refers to the fluid whose conveying medium is slurry (not clear liquid). It is a pump named after the type of conveying medium. It is specially used to convey solid particles, easy to crystallize, viscous, ore slurry, Designed and developed for the special fluid medium of the desulfurization circulating fluid, the general material of the slurry pump is: lining high molecular polyethylene, special wear-resistant alloy, 2205 duplex stainless steel, ordinary stainless steel and other materials; according to different working conditions, choose Different materials; the main features are wear resistance, impact resistance, creep resistance and corrosion resistance. [0003] A slurry pump is a vane pump, which...
