Yesterday afternoon, a high pressure magnetic drive circulating pump customized by Shanghai Lingnai Special Magnetic Pump Co., Ltd. has undergone rigorous pressure test and inspection, and has been successfully delivered to the customer. This is another new high-performance magnetic pump product customized by Shanghai Lingnai (Jinai) as a special magnetic pump research and development factory for customers.

The high pressure magnetic drive circulating pump uses static seals instead of dynamic seals, so that the flow parts of the pump are in a completely sealed state, and completely solves the disadvantages of running, emitting, dripping and leaking that cannot be avoided by other pump mechanical seals. High-pressure magnetic drive circulating pumps The body and flow parts are made of corrosion-resistant stainless steel material, which not only has the function of a magnetic drive pump, but also integrates self-priming. It does not require a bottom valve and irrigation water, and the self-priming height can reach 4 meters.

The design difficulty of this high pressure magnetic drive circulating pump lies in the high-pressure design requirements. The high-pressure magnetic pump designed by Shanghai Lingnai can withstand a pressure of up to 40Map.

The high pressure magnetic drive circulating pump adopts an external-mixing axial return water pump body structure. The pump body is composed of a liquid suction chamber, a liquid storage chamber, a volute, a return hole, and a gas-liquid separation chamber. After the pump is started, the centrifugal force acts on The remaining liquid in the suction chamber and the air in the liquid inlet pipe are stirred by the impeller to form a gas-liquid mixture. The mixture enters the gas-liquid separation chamber through the volute. As the speed slows down, the gas and water separate, and the air is pumped out of the liquid. The liquid is discharged from the port, and the liquid returns to the pump through the water return hole. After multiple cycles, the air in the liquid inlet pipe is drained, so that a certain degree of vacuum is formed in the pump to achieve the effect of self-priming.

This high pressure magnetic drive circulating pump designed by Shanghai Lingnai has a compact structure, beautiful appearance, small size, low noise, reliable operation, and convenient use and maintenance. The product can be used in petroleum, chemical, pharmaceutical, electroplating, printing and dyeing, food, scientific research and other units to pump acids, alkalis, oils and rare and precious liquids, venoms, volatile liquids, and supporting circulating water equipment, especially leaking, flammable, Pumping of explosive liquids.
