Embodiment Construction

[0018] refer to figure 1 , which includes front cover 1, main shaft 2, front shaft sleeve 3, pump body 4, impeller and rotor assembly 5, rear cover 6, spacer sleeve pressure plate 7, rear shaft sleeve 8, bracket 9, motor 10, spacer sleeve combination 11 , External magnetic 12, sealing ring 13.

[0019] The main shaft is made of steel tightly packed with corrosion-resistant and wear-resistant plastic, and is fixed on the front cover with bolts through cooperation. The plastic on the outer layer of the main shaft has a lubricating and cooling spiral groove. The water inlet of the pump body and the front cover form a water inlet chamber. The body is designed with a support ring composed of support feet inside the water inlet chamber. The support ring is tightly fitted with a front bushing. The main shaft passes through the front bushing and is tightly fitted with the front bushing. The rear shaft sleeve, the impeller and the rotor assembly are set on the main shaft, and are syn...

Abstract

The invention discloses a magnetic pump and relates to the technical field of delivery of highly corrosive chemical liquid. The magnetic pump is characterized in that the magnetic pump comprises a front cover, a main shaft, a front shaft sleeve, a pump body, an impeller and rotor assembly, a rear cover, a spacer sleeve pressing plate, a rear shaft sleeve, a support, a motor, a spacer sleeve assembly, an outer magnet and a sealing ring. All the components making contact with the chemical liquid are lined with corrosion-resistant plastic or made of corrosion-resistant materials. According to the magnetic pump, the fault that a non-metal main shaft is prone to breakage is avoided. Another embodiment can be used for chemical liquid containing crystalline particles. The use environment of the magnetic pump is widened, the reliability of the magnetic pump is improved, the life-cycle cost of the magnetic pump is reduced, and the magnetic pump meets the strict environmental friendliness requirement in the chemical industry.

Description

technical field [0001] The invention relates to the technical field of highly corrosive chemical liquid transportation, in particular to a magnetic pump. Background technique [0002] At present, the main shaft of the ordinary magnetic pump used in the strong corrosive chemical liquid mainly has two supporting methods, type A (see attached image 3 ): The main shaft is fixed on the spacer sleeve, and the impeller and rotor are integrated. Since the main shaft is fixed on the isolation sleeve, the isolation sleeve must have good mechanical strength and can bear various loads generated during the operation of the impeller and rotor, so metal isolation sleeves are often used. However, the use of metal spacers in highly corrosive environments has limited the use of magnetic pumps. If the isolation sleeve is made of corrosion-resistant plastic, the plastic isolation sleeve must not only bear the internal pressure of the magnetic pump, but also bear various loads of the operation...
