The working principle of explosion-proof stainless steel magnetic pump is applied to the new product of centrifugal pump, which has the characteristics of reasonable design, full sealing, no leakage, and corrosion resistance.
Explosion proof stainless steel magnetic pumpPrecautions for use:
1. As the cooling and lubrication of the magnetic pump bearings rely on the medium being transported, it is prohibited to operate them without load, and at the same time, it is necessary to avoid idle operation caused by restarting after a power outage during operation.
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 needs to 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. The operating temperature of engineering plastic pumps is less than 60 ℃, the operating temperature of metal pumps is less than 100 ℃, the auxiliary suction pressure is not greater than 0.2MPa, the high working pressure is 1.6MPa, the density is not greater than 1600 ^ kg/m3, and the particle size is not greater than 30 X 10-6 ㎡/S of 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 and the accumulated liquid in the pump should be drained.
After 500 hours of operation of the magnetic pump, the wear and inertia of the bearings and end face moving rings should be inspected. If the gap between the bearings and the shaft sleeve is greater than 0.5-1mm, the axial displacement of the impeller should be 1.5 degrees? When 2mm, the bearing and axial moving ring should be replaced.
Explosion proof stainless steel magnetic pumpBy replacing dynamic seals with static seals, the overcurrent components of the pump are in a sealed state, which solves the problems of running, emitting, and dripping that cannot be avoided by mechanical seals of other pumps. Magnetic pumps use corrosion-resistant and high-strength engineering plastics, steel jade ceramics, and stainless steel as manufacturing materials, so they have good corrosion resistance and can protect the transported medium from pollution. 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, national defense, scientific research institutions, metallurgy, dyes and other units to pump acid, alkali solution, rare and valuable oil liquids, venom, volatile liquids, as well as supporting circulating water equipment and filter machines. Especially for the pumping of liquids that are prone to leakage, combustion, and explosion. This pump is a more ideal equipment for explosion-proof motors.
