Briefly introduce the magnetic drive pump
A magnetic drive pump (referred to as a magnetic pump for short) applies the principle of modern magnetomechanics, that is, when the motor drives the outer rotor (i.e., outer magnetic steel) assembly to rotate, through the action of the magnetic field, the magnetic force line passes through the isolation sleeve to drive the inner rotor (i.e., inner magnetic steel) assembly and impeller to rotate synchronously. Since the medium is sealed in the static isolation sleeve, the purpose of no leakage pumping medium is achieved, and the leakage of shaft seal of mechanical drive pump is completely solved Industrial pump without leakage and pollution.
Application of magnetic drive pump
Precautions for maintenance of magnetic drive pump
A magnetic drive pump is an ideal pump to eliminate running, emitting, dripping and leakage in chemical processes, eliminate environmental pollution, create a "leak-free workshop" and "leak-free factory", and realize safe and civilized production
Magnetic drive pump is widely used in the production process of petroleum, chemical, pharmaceutical, printing and dyeing, electroplating, food, environmental protection, and other enterprises to transport corrosive liquids without iron filings, especially for the transportation of flammable, explosive, volatile, toxic and precious liquids. A magnetic drive pump is a new type of pump that uses the working principle of magnetic coupling to transfer torque without contact. When the motor drives the outer magnetic rotor to rotate, it drives the inner magnetic rotor to rotate synchronously with the impeller through the action of the magnetic field, so as to achieve the purpose of pumping liquid. Because the liquid is enclosed in a static isolation sleeve, it is a fully sealed and leak-free pump.
Precautions for magnetic pump maintenance
l Pump shaft broken
The pump shaft of the MDW magnetic pump is made of pure silicon carbide. The main reason for the fracture of the pump shaft is that the shaft is broken due to the empty operation of the pump and the dry grinding of the bearing. When the pump is disassembled for inspection, it can be seen that the bearing has been seriously worn. The main way to prevent the pump from breaking is to avoid idling the pump.
Insufficient lift
The reasons for this failure are: there is air in the conveying medium, the impeller is damaged, the speed is not enough, the specific gravity of the conveying liquid is too large, and the flow is too large.
nsufficient flow.
The main causes of insufficient flow are impeller damage, insufficient speed, high head, sundries blocking the pipe, etc.
The pump cannot pump out the liquid.
The failure of the pump to pump liquid is the most common failure of the pump, and there are many reasons. First, check whether there is air leakage in the suction pipe of the pump, whether the air in the suction pipe is discharged, whether the amount of liquid filled in the pump is sufficient, whether there are sundries blocked in the suction pipe, whether the pump is reversed (especially after changing the motor or after the maintenance of the power supply line), and whether the suction height of the pump is too high. By
If it still cannot be solved through the upper inspection, the pump can be disassembled for inspection to see whether the pump shaft is broken and whether the moving ring and static ring of the pump are intact.
Taicang magnetic centrifugal pump Co., Ltd. was born in 1979. It cooperated with Shanghai Chemical Design Institute to form a unique core research project with magnetic drive pump, and achieved great success. It has become the first company in China to comprehensively design and produce magnetic drive pump. Today, Taicang magnetic centrifugal pump Co., Ltd. has become a leading manufacturer of magnetic drive pumps in China, with many patents and 12 utility model patents.
