Overview of YW series unobstructed submersible sewage pump: The working principle of permanent magnet coupling is applied to the new product of centri
Product details
product overview
Applying the working principle of permanent magnet couplings to new products of centrifugal pumps, with reasonable design, advanced technology, fully sealed, leak free, and corrosion-resistant characteristics, its performance has reached the advanced level of similar foreign products.
Magnetic pumps replace dynamic seals with static seals, ensuring that the overcurrent components of the pump are completely sealed, completely solving the problem of leakage, seepage, and dripping that cannot be avoided by other pump mechanical seals. Magnetic pumps use corrosion-resistant and high-strength engineering plastics, corundum ceramics, stainless steel, and other materials as manufacturing materials, so they have good corrosion resistance and can protect the transported medium from pollution.
purpose
Magnetic pump has a compact structure, beautiful appearance, small volume, low noise, reliable operation, and easy use and maintenance. It can be widely used in chemical, pharmaceutical, petroleum, electroplating, food, film photography and printing, scientific research structures. National defense industry and other units pump acid, alkali solution, oil, rare and valuable liquids, venom, volatile liquids, as well as supporting equipment for circulating water and filter machines. Especially for the pumping of liquids that are prone to leakage, flammable, and explosive, this pump is more ideal.
(1) The models of engineering plastic pumps (reinforced polypropylene) are:
08CQ-2, 10CQ-3, 14CQ-5, 16CQ-8, 20CQ-12, 32CQ-15, 32CQ-25, 40CQ-20, 50CQ-25, 50CQ-32.
(2) The models of stainless steel pumps (1Cr18Ni9Ti) include:
16CQ-8, 20CQ-12, 32CQ-15, 32CQ-25, 40CQ-20, 40CQ-32, 50CQ-25, 50CQ-40, 50CQ-50, 65CQ-25, 65CQ-35, 80CQ-35, 80CQ-50.
For example: （50CQ-25）
（1） Magnetic pumps should be installed horizontally and not vertically. The plastic pump body should not bear the weight of the pipeline. For special requirements for vertical installation, the motor must face upwards.
（2） When the suction liquid level is higher than the pump axis line, open the suction pipeline valve before starting. If the suction liquid level is lower than the pump axis line, the pipeline needs to be equipped with a bottom valve.
（3） Before using the pump, it should be checked that the motor fan blades rotate flexibly, without jamming or abnormal noise, and the fasteners should be tightened.
（4） Check if the rotation direction of the motor is consistent with the direction mark of the magnetic pump.
（5） After the motor starts, slowly open the discharge valve and adjust it to the desired opening after the pump enters normal operation.
（6） Before the pump stops working, the discharge valve should be closed first, and then the suction pipe valve should be closed.
（1） Due to the fact that the cooling and lubrication of the magnetic pump bearings rely on the medium being transported, it is absolutely forbidden to operate them without air, and at the same time, it is necessary to avoid spatiotemporal load rotation caused by power outages during operation and startup.
（2） If the conveyed medium contains solid particles, a filter screen should be added to the pump inlet; if it contains ferromagnetic particles, a magnetic filter should be added.
（3） The ambient temperature of the pump during use should be less than 40 ℃, and the temperature rise of the motor should not exceed 75 ℃.
（4） The conveyed medium and its temperature should be within the allowable range of the pump material (see attached table for details). The operating temperature of engineering plastic pumps is less than 60 ℃, the operating temperature of metal pumps is less than 100 ℃, the conveying suction pressure is not greater than 0.2MPa, the maximum working pressure is 1.6MPa, the density is not greater than 1600kg/m ³, and the particle size is not greater than 30 × 30-6 ㎡/S, which is a liquid without hard particles and fibers.
（5） For media that are prone to precipitation and crystallization during transportation, they should be cleaned promptly after use to drain the accumulated liquid in the pump.
（6） After 500 hours of operation of the magnetic pump, the wear of the bearings and end face dynamic rings should be disassembled and inspected. If the gap between the bearings and the shaft sleeve is greater than 0.5mm~1mm and the axial displacement of the impeller is 1.5~2mm, the bearings and axial dynamic rings should be replaced.
