Magnetic drive pump is a high safety level of high-quality anti-leakage pump, know the principle and maintenance of magnetic pump can effectively improve the stability of transportation projects, but also to a certain extent to reduce misoperation, for extending the service life of the pump is also of great significance.
As for the principle and maintenance of magnetic pump, we first understand from the principle that the driving mode of magnetic pump and other electric pumps are driven by motors. Its core component is a magnetic drive composed of internal and external magnetic rotors. The structure can transfer kinetic energy without mechanical contact, which is the main reason why magnetic pump can not leak a drop during transportation. When the magnetic pump is used, the kinetic energy of the motor drives the external magnetic rotor to rotate. The magnetic force generated by the motor can penetrate the air gap and other non-magnetic substances and synchronously drive the internal magnetic rotor connected with smelting, so as to transfer power. There is no mechanical contact in the transmission process, which changes the dynamic seal into a static seal, thus greatly improving the safety.
In terms of maintenance, it is recommended to make regular maintenance plan in advance. It is usually recommended to carry out a routine inspection every one thousand hours. If the pump environment is poor, the maintenance and maintenance time can be shortened accordingly. Routine inspection and maintenance contents are as follows: after disassembling the pump body, check the aging and wear of bearing and end face moving ring and other vulnerable parts, check whether the clearance is normal, and other moving components also need to be checked step by step. In daily transportation, if the treated medium is easy to precipitate or crystallized, pay attention to cleaning the pump cavity and draining the accumulated liquid after stopping the pump.
In terms of operation, the magnetic pump needs to be manually turned before starting to ensure flexible operation without astringency. The tightness of each fastener should also be confirmed. After starting, the discharge valve needs to be opened slowly, and the opening of the discharge valve can be adjusted after the operation parameters of the pump are stable. It should be noted that the magnetic pump is strictly prohibited idling, in the process of operation should always monitor the running state, to avoid the media due to accidental cut-off, but also to avoid long time low flow operation, in the transport medium and pipeline pump can only deal with the composition of the liquid close to water, not like the screw pump to deal with the media containing granular debris, otherwise there will be the risk of blockage and wear.
