Abstract

Disclosed is a disc-type magnetically connected chemical sliding vane pump, which is used for conveying various oils and chemical media. It includes motor, connection plate, disc-type external magnetic rotor, pump body with eccentric inner cavity, internal magnetic rotor with groove, pump shaft, sliding plate, circular magnet, sliding bearing, hard alloy moving ring, silicon carbide static ring, Round nut, pump back cover. The inner magnetic rotor of the present invention is integrated with the slotted rotor of the sliding vane pump to become an inner magnetic rotor with slots. Due to the change of the magnet installation method embedded in the outer magnetic rotor and the inner magnetic rotor with slots, the ring magnetic connection structure is changed to The disc-type magnetic connection structure directly uses the thin wall on the side of the pump body to isolate the outer magnetic rotor and the inner magnetic rotor with grooves, which cancels the isolation sleeve necessary for the previous ring-type magnetic pump, shortens the length of the pump body, and makes the structure simpler and more compact. The maintenance efficiency is greatly improved, the skill requirements for maintenance personnel are reduced, and the high efficiency and energy saving of the pump are realized.

Description

technical field

[0001] The invention relates to the field of chemical machinery, in particular to a disc-type magnetic connection chemical sliding vane pump with simple structure and low manufacturing, maintenance and maintenance costs. Background technique

[0002] Magnetic pumps are mainly used in all loading and unloading liquid transportation conditions such as trains, liquid terminals, tankers, tank cars, and chemical tank dumping. It consists of an outer magnetic assembly, an inner magnetic assembly and a non-magnetic isolation sleeve. When the external driving force drives the outer magnetic assembly to rotate, the magnetic field can penetrate the air gap and non-magnetic substances, and drive the inner magnetic assembly connected to the impeller for synchronization. Rotating, a new type of pump that realizes the non-contact synchronous transmission of power. At present, magnetic drive pumps are mainly divided into magnetic drive gear pumps, magnetic drive centrifuga...
