Magnetic Drive Pumps is a new product that applies the working principle of permanent magnet coupling to centrifugal pumps, with reasonable design, full sealing, no leakage, and corrosion resistance at the leading edge of the process, and its performance has reached the leading level of similar foreign products. Magnetic Drive Pumps replace dynamic seals with static seals so that the pump's wetted parts are completely sealed.

Cooling Circulation System for Magnetic Drive Pumps.
Most Magnetic Drive Pumps have a set of cooling circulation systems, and there are often two circulation methods. The internal circulation mode of Magnetic Drive Pumps leads out a high-pressure circulating medium in the pump near the outlet of the impeller. Most of the high-pressure fluid passes through the narrow gap between the inner magnetic rotor and the isolation sleeve, flows through the central hole of the pump shaft or other channels, and returns to Metallic The suction mouth of Magnetic Drive Pumps. Another small part passes through the thrust end face of the thrust bearing and the sliding bearing and then returns to the suction port after passing through the lubricating oil groove of the sliding bearing to complete the lubrication and cooling of the spacer sleeve, the sliding bearing, and the thrust bearing. The external circulation method of Magnetic Drive Pumps leads to a high-pressure circulating medium from the high-pressure area of the pump outlet. lubrication and cooling effect.
Axial force generation and balancing system for Magnetic Drive Pumps.
The generation of the axial force of Magnetic Drive Pumps is mainly composed of the following parts: the axial force caused by the inconsistent pressure on the front and rear cover plates of the impeller, the axial force caused by the introduced high-pressure cooling circulating fluid on the inner magnetic rotor, the impeller in The dynamic reaction force acting on the impeller when work is performed on the medium, and the axial force acting on the end face of the thrust bearing by the pump population pressure of the transported medium. As a result of the above axial force, a very huge axial force is generated, which acts on the entire rotor component and points to the pump population, usually in the thousands or even tens of thousands of N. The thrust bearings of Magnetic Drive Pumps are not capable of withstanding such large axial forces. Therefore, to ensure that the thrust bearing can work safely and stably for a long time, it is necessary to balance the axial force in the pump. There are many ways to balance the axial force in Magnetic Drive Pumps, one of which is the hydraulic self-balancing system of the axial force in the pump. By changing the force area of the front and rear cover plates of the impeller, when the pressure generated by the impeller acts on the front and rear cover plates, a force equal to or close to the size of the impeller will be generated on the impeller, but it is opposite to the axial force acting on the entire rotor. Thereby the axial forces in the pump are substantially balanced. After the hydraulic self-balancing of the axial force in the pump, the axial force on the thrust bearing can be controlled within a small range, and the end faces specific pressure on the thrust bearing can also be controlled within a reasonable range.
