Magnetic gear pump is mainly used in wet corrosion cleaning equipment as follows:
(1) Circulating filtration of liquid medicine: the circulating filtration system of liquid medicine is composed of magnetic gear pump, circulating overflow tank, filter, pipe fittings, etc. Realize the circulating filtration of liquid medicine and ensure the uniformity of liquid medicine temperature and concentration in the process tank. The magnetic gear pump is not suitable for the process tank with high temperature control accuracy because it will cause a certain temperature rise of the liquid medicine during long-term operation. It is often used in solar cell pickling, cashmere making, cleaning and other equipment.
(2) Hot water injection and spraying: wafers treated with chemical solution sometimes need hot DI water spraying and flushing. Generally, DI water is first injected into the preheating tank, heated to the required liquid supply temperature through the heater, and then pressurized and delivered to the sprinkler through the magnetic gear pump to clean the wafer. Because the sliding friction of magnetic gear pump bearing will produce particles, it is not suitable for cleaning with high particle requirements.
At present, there are three main materials of magnetic gear pump: PP, PVDF and ETFE. Select appropriate pump body materials, bearing materials and sealing ring materials according to different solutions. The maximum operating temperature of magnetic gear pumps made of PP, PVDF and ETFE plastic pump bodies is 80 ℃, and the maximum operating temperature of special models is 100 ℃ (assomaamxi Series in Taiwan). The viscosity of the medium has a great impact on the performance of the pump. When the viscosity increases, the head curve of the pump decreases, the head and flow under the best working condition decrease, while the power increases, so the efficiency decreases. For the medium with high viscosity, the magnetic gear pump with small head may not work. On the premise of meeting the flow requirements, the magnetic gear pump used for spray flushing can achieve better cleaning effect by selecting a head of more than 20m.
