Precautions For The Operation Of Chemical Magnetic Pump
TIME：2024-06-03 Author：admin Views：
Magnetic drive pumps lead to bearings subjected to impeller and pump shaft radial imbalance force, there are two major categories of pasteurized alloy bearings and non-metallic bearings, the latter take the water smooth, simple structure, reliable task, but poor wear resistance; the former wear resistance is good, but the structure of the complexity of the oil self-circulation system and the above water seal installation often fails to destroy the bearings, affecting the reliability of the non-metallic water smooth bearings instead of the tendency to be replaced by the water smooth bearings.
Take non-metallic bearing magnetic drive pump running for a period of time, bearing and journal wear, bearing radial clearance increases, the spindle and impeller dynamic swing increases, radial clearance increases to a certain value must be overhauled to solve the problem, otherwise, the impeller, pump shaft transverse vibration ferocious, and further will form the vane touching the shell. The solution is to spray plating journal, car round or change the bearing.Take non-metallic bearing magnetic drive pump running for a period of time, bearing and journal wear, bearing radial clearance increases, the spindle and impeller dynamic swing increases, radial clearance increases to a certain value must be overhauled to solve the problem, otherwise, the impeller, pump shaft transverse vibration ferocious, and further will form the vane touching the shell.

Here are the precautions for the operation of chemical magnetic pump：
1. Idle running is strictly prohibited.
2. It is strictly prohibited to pump out the medium.
3. In the case of the outlet valve is closed, the chemical horizontal magnetic pump continuous running time shall not exceed 2min, in order to prevent the magnetic actuator overheating and failure.
4. The magnetic torque should not be designed too small.
5. It should be operated under the specified temperature conditions, and it is strictly prohibited for the medium temperature to exceed the standard. Platinum resistance temperature sensor can be installed on the outer surface of the isolation sleeve of the chemical horizontal magnetic pump to detect the temperature rise of the annular gap area so as to alarm or shut down when the temperature exceeds the limit.
6. When conveying the medium containing solid particles, it should be filtered at the entrance of the pump flow pipe.
The features of the chemical magnetic pump :
1. Adaptable to chemical process requirements
2. Corrosion resistance
3. Resistant to high and low temperatures
4. Wear-resistant, scour-resistant
5. Reliable operation
6. No leakage or less leakage
7. Capable of conveying the critical state of the liquid
8. Vapor corrosion resistance
Chemical magnetic pump product application:
It can be used as sulfuric acid transfer pump, nitric acid pump, hydrochloric acid pump, hydrofluoric acid pump, phosphoric acid pump, acid unloading pump, unloading pump, dosing pump, acid washing pump, acid circulation pump, acid circulation pump, lye pump. Reasonable design, advanced technology, with full seal, no leakage, extremely strong corrosion resistance, etc.,widely used in: chemical industry, acid production, alkali production, smelting, rare earth, pesticides, dyes, pharmaceuticals, papermaking, electroplating, pickling, radio, scientific research institutes, national defense industry, etc., pumping acid, lye pumping.
