Description

Technical Field

[0001] The utility model relates to the field of magnetic pumps, in particular to a shock-absorbing magnetic pump. Background Art

[0002] A magnetic pump is a power device used for transportation, generally referring to a plastic acid- and alkali-resistant magnetic pump (magnetic drive pump), which is mainly composed of a pump head, a magnetic actuator (magnetic cylinder), a motor, a connecting base plate, and other parts. The magnetic actuator of a magnetic pump consists 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, the magnetic field can penetrate the air gap and non-magnetic materials, driving the inner magnetic rotor connected to the impeller to rotate synchronously, realizing contactless synchronous transmission of power, and converting a dynamic seal structure prone to leakage into a static seal structure with zero leakage.

[0003] The common magnetic pumps currently have poor shock absorption performance. During operation, the magnetic pumps often generate large noise and vibration due to mechanical vibration and fluid pulsation. The vibration may not only cause the magnetic pump itself to be displaced, thus affecting the stable operation and reliability of the equipment, but may also cause interference to the surrounding environment. Therefore, the utility model provides a shock-absorbing magnetic pump to solve the problems raised in the above background technology. Utility Model Content
