1CQG high-temperature resistant magnetic drive pumpProduct Overview:
With the need for modernization of China's petrochemical facilities, in order to quickly adapt to equipment upgrades centered on energy conservation and develop products produced in accordance with the APl610 plan that are in line with international advanced standards. Recently, our unit, together with relevant experts in the pump industry, jointly researched, discussed, and invented the CQG type high-temperature resistant magnetic drive pump series that has reached the international advanced level, filling the domestic gap.
IICQG high-temperature resistant magnetic drive pumpProduct Usage:
High temperature resistant magnetic drive pumps are used in petroleum refining, petrochemicals, chemical industries, and other places to transport special petroleum, printing and dyeing raw materials, and their high-temperature media (operating temperature t<300 ℃).
IIIProduct features:
The design of Yingke brand has the characteristics of high reliability, long service life, and high universality. Magnetic drive pump, also known as shaftless pump, replaces dynamic seal with static seal, so that the overcurrent components of the pump are completely sealed. Due to the use of magnetic coupling transmission, it can replace the problems of running, emitting, dripping, and leaking that cannot be solved by the original mechanical pump mechanical seal.
A pump without a shaft seal is a pump with zero leakage because it has no shaft seal.

Model Description: CQG High Temperature Magnetic Drive Pump (Operating Temperature T ≤ 300)⁰C)

VIInstallation and use:
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 all fasteners should be tightened.
4. Check if the motor rotation direction matches the magnetic pump direction mark *.
5. After the motor starts, slowly open the discharge valve and adjust it to the desired opening after the pump enters normal operation.
7Precautions for use:
1. Due to the fact that the cooling and lubrication of magnetic pump bearings rely on the medium being transported, it is absolutely forbidden to operate them in idle mode, while also avoiding the possibility of spatiotemporal rotation caused by power outages and restarts during operation.
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/m3, the particle size is not greater than 30 × 10-6m2/s, and the liquid does not contain 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 running the pump for 1500 hours, the wear of the bearings and end face moving rings should be disassembled and inspected, and vulnerable parts that are no longer suitable for use should be replaced.
7. The magnetic couplings inside and outside the pump are made of high-performance permanent magnet materials, which may pose potential hazards to the following components. Please keep the following components at a distance from this series of pumps. Such as pacemakers, cards and other magnetic cards, calculators, computer disks, watches, etc.
8Malfunctions and troubleshooting:

failure mode

cause

Troubleshooting

The pump is not producing water

	1. Reverse rotation of water pump
	2. Leakage at the beginning of the inlet pipe
	3. Insufficient water storage in the pump chamber
	4. The voltage is too high, causing the coupling to slip during startup
	5. The suction distance is too high

	Change the motor wiring
	Eliminate air leakage

	Adjust the positive voltage
	Installation position of Longlow pump

Insufficient traffic

	1. The suction pipe diameter is too small
	2. Impeller channel blockage
	3. Head too high
	4. The speed is too low

	Replace the inlet pipe
	Clean the impeller
	Turn up the outlet valve
	Restore rated speed

Low head

1. Excessive traffic

2. The speed is too low

Turn down the outlet valve

Restore rated speed

too much noise

2. Severe wear of the shaft sleeve

3. 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

O-ring damaged

Replace the O-ring seal
