Abstract

The invention belongs to the technical field of heat-resistant magnetic pumps, and particularly relates to an intelligent temperature-control high-temperature-resistant fluorine-lined magnetic pump. The intelligent temperature-control high-temperature-resistant fluorine-lined magnetic pump comprises a pump body, a pump body static ring, an impeller, a pump shaft, a shaft sleeve, an isolation sleeve assembly, a thrust bearing, a pressing plate, a support, an external magnetic component and a temperature sensor. The shaft sleeve is of a spiral groove type. The impeller and the shaft sleeve are assembled together to form an impeller assembly. The pump body static ring, the thrust bearing and the isolation sleeve assembly are assembled together to form a supporting assembly. Blades are arranged on the back of the external magnetic component. The isolation sleeve assembly is formed by assembling an inner isolation sleeve and an outer isolation sleeve together. The joint of the support and the motor is of a double-layer structure, so that a cavity is formed. A detection opening is formed outside the pump body. The temperature sensor is arranged in the detection opening. Compared with theprior art, the intelligent temperature-control high-temperature-resistant fluorine-lined magnetic pump has the following advantages that the medium temperature is monitored in real time through reasonable structure arrangement and scientific material selection, the pump is ensured by an intelligent system, the maintenance cost is reduced, and the intelligent temperature-control high-temperature-resistant fluorine-lined magnetic pump can operate under a high-temperature condition for a long time and can improve economic benefits.

[0002] The high temperature magnetic pump is a kind of non-contact torque transmission through the magnetic drive, so that the dynamic seal is replaced by the static seal, so that the pump is completely leak-free. Since the pump shaft and the inner magnetic rotor are completely sealed by the pump body and the isolation sleeve, it is completely solved. It eliminates the problem of "running, leaking, dripping, and leaking", eliminates the potential safety hazards of flammable, explosive, toxic, and harmful media leaking through the pump seal in the refining and chemical industry, and effectively guarantees the physical and mental health of employees and safe production. High temperature magnetic pump It is composed of three parts: self-priming pump, magnetic drive and motor; the key component of the magnetic drive is composed of outer magnetic rotor, inner magnetic rotor and non-magnetic isolation sleeve; the existing high temperature magnetic drive pump is widely used in petroleum refining, petroleum The chemical industry and chemical industry and other places transport special petroleum, printing and dyeing raw materials and other high-temperature media, which have the characteristics of high safety, long service life and high degree of generalization. With the continuous development of the chemical industry, the requirements for magnetic pumps are getting higher and higher. The higher the increase, the higher the requirements for the anti-dry wear and corrosion resistance of the static ring of the pump body, the pump shaft and the thrust bearing of the magnetic pump. Under the production conditions of high temperature and high pressure, the long-term working shaft may occur The existing high-temperature magnetic pump is cooled by external cooling water to protect the motor. However, although cooling with cooling water for a long time can achieve the effect of heat isolation and protection of the motor, it requires more cooling water and consumes a lot of energy. , increasing operating costs
