Description

Technical Field

[0001] The utility model relates to the field of magnetic pumps, and more specifically to a quick-detachable magnetic pump head. Background Art

[0002] The magnetic pump is mainly composed of several parts such as the pump head, magnetic transmission (magnetic cylinder), motor, base, etc. The magnetic transmission of the magnetic pump is composed of an outer magnetic rotor, an inner magnetic rotor and a non-magnetic isolation sleeve. When the motor drives the outer magnetic rotor to rotate through the coupling, the magnetic field can penetrate the air gap and the non-magnetic isolation sleeve, driving the inner magnetic rotor connected to the impeller to rotate synchronously, realizing contactless synchronous transmission of power.

[0003] The structural components of a magnetic pump are generally divided into a motor, a mounting frame, and a pump casing. In the organization, the motor is fixed to the mounting frame by bolts, and then the mounting frame is fixed to the pump casing by bolts. When installing and repairing the pump, the motor must be removed first. Since the maintenance cycle of the pump is relatively long, the bolts between the motor and the mounting frame, and the bolts between the mounting frame and the pump casing are usually difficult to remove, and the modification is stuck, which is time-consuming and labor-intensive, and difficult to disassemble, which brings difficulties to the maintenance of the pump. To address this problem, a Chinese utility model with application number 202321623737.X proposes a quick-detachable magnetic pump head. The utility model is provided with a disc, a slider, a slide column, a housing, a pump casing, a mounting frame, a motor, a rotating shaft, and a gear. When the magnetic pump needs to be maintained and the motor needs to be removed, the gear is driven to rotate by rotating the rotating shaft, and the rotation of the gear drives the disc to rotate. The disc drives the sliders to move away from each other through the slide column, so that the sliders are separated from the sockets of the mounting frame, and then the motor and the mounting frame can be lifted to remove the motor, so that the device can conveniently remove the motor by rotating the rotating shaft as needed; however, the problems existing when the mounting frame and the pump casing are installed and connected by the device are as follows:

[0004] The overall structure of the disc is complex and contains a large number of precision components. When the mounting frame is installed and fixed by multiple sets of sliders and matching springs, the fixing effect is poor. It is easy for a single set of matching springs and sliders to break and get stuck. Once a single set of matching springs and sliders fails, the entire disc will not be able to achieve limit fixation on the mounting frame.

[0005] Therefore, the utility model proposes a detachable magnetic pump head. Utility Model Content
