Product Overview:
CQ type magnetic drive pump (referred to as magnetic pump) is a new product that applies the working principle of permanent magnet coupling to centrifugal pumps. It has a reasonable design, advanced technology, fully sealed, leak free, corrosion-resistant and other characteristics. Its performance has reached the advanced level of similar foreign products.
Main features:
Magnetic pumps replace dynamic seals with static seals, ensuring that the overcurrent components of the pump are in a completely sealed state, completely solving the problems of running, emitting, and dripping that cannot be avoided by other pump mechanical seals. Magnetic pumps use corrosion-resistant and high-strength engineering plastics, steel jade ceramics, stainless steel and other materials as manufacturing materials, so they have good corrosion resistance and can protect the transported medium from pollution.
Product Usage:
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 institutions, national defense industry and other units to pump acid, alkali solution, oil, rare and precious liquids, venom, volatile liquids, as well as supporting circulating water equipment and filter machines. Especially for the pumping of leaked, flammable, and explosive liquids, this pump is more ideal.

Installation and use:
1. The magnetic pump 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.
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 sound, and all 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.
Before the pump stops working, the discharge valve should be closed first, and then the suction pipe valve should be closed.
Precautions for use:
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.
Malfunctions and troubleshooting:

Troubleshooting |
|
The pump is not producing water |
Reverse rotation of water pump Leakage of water pipeline Insufficient water storage in the pump chamber The voltage is too high, causing the coupling to slip during startup The suction distance is too high |
Change the motor wiring Social isolation leakage Increase storage capacity Adjust the positive voltage Lower the installation position of the pump |
|
Insufficient traffic |
The suction pipe diameter is too small Impeller channel blockage Head too high The speed is too low |
Replace the inlet pipe Clean the impeller Turn up the outlet valve Rated speed of Huixia |
|
Low head |
Excessive traffic The speed is too low |
Turn down the outlet valve Restore rated speed |
|
The sound is too loud |
Severe wear of the shaft Severe wear of the shaft sleeve Drive the magnetic steel cup to contact the isolation sleeve |
Replace the pump shaft Replace the shaft sleeve Dismantle the pump head and reassemble it |
|
Leakage of liquid |
Type 0 sealing ring damaged |
Replace the 0-type sealing ring |
