Detailed specifications of the CQB magnetic drive pump

I. Overview of CQB Type Magnetic Drive Pump

The magnetic drive pump is designed based on the centrifugal pump in the impeller pump, but it utilizes the magnetic transmission principle for the drive mechanism. As the centrifugal magnetic drive pump operates on the same principle as the centrifugal pump, primarily relying on the centrifugal force generated by the rotation of one or more impellers to transport fluids, it is named as a magnetic drive pump. The CQB magnetic drive pump is designed and modified based on the original CQ type stainless steel magnetic pump, with the same structure and principle except for the drive and sealing methods.

The CQB magnetic drive pump is a supplement and improvement to the CQ magnetic pump. The flow part of this magnetic pump is made of all stainless steel material, which boasts excellent corrosion resistance to organic acids, organic compounds, alkalis, neutral solutions, and various gases. The wear resistance is enhanced through the磨合 of double helical groove carbon graphite bearings and hard alloy shaft sleeves, ensuring the product's lifespan and making it an ideal pump for leak-free transfer of corrosive media. It can directly replace the IH stainless steel chemical pump as an ideal pump type for leak-free transfer of corrosive media.

Section 2: Installation and Operation of CQB Type Magnetic Drive Centrifugal Pumps

1. Magnetic drive pumps should be installed horizontally, not vertically. The plastic pump housing should not bear the weight of the piping. For applications requiring vertical installation due to special requirements, the motor must face upwards.

2. When the liquid level being suctioned by the CQB magnetic pump is above the pump's shaft centerline, simply open the suction pipe valve before starting the magnetic drive pump. If the liquid level is below the pump's shaft centerline, a bottom valve must be installed in the pipe.

3. Before use, magnetic drive centrifugal pumps should be inspected. The motor impeller should rotate smoothly without any jamming or unusual noises, and all fasteners should be securely tightened.

4. Check if the motor's rotation direction matches the directional indicator * on the magnetic pump.

5. After the motor starts, gradually open the discharge valve. Once the pump reaches normal operating conditions, adjust the discharge valve to the required opening.

6. Prior to stopping work, the discharge valve should be closed first, followed by the intake pipe valve.

Section 3: CQB Magnetic Drive Pump Usage Precautions

1. Due to the cooling and lubrication of magnetic pump bearings being dependent on the conveyed medium, it is prohibited to run the pump without medium. Additionally, it is important to avoid restarting the pump after a power outage during operation, which could lead to empty running.

2. If the conveyed medium contains solid particles, a filter screen should be added to the magnetic drive pump's inlet; if ferromagnetic particles are present, a magnetic filter is required.

3. During operation, the ambient temperature should be less than 40°C, and the motor temperature rise should not exceed 75°C.

4. The medium being conveyed and its temperature should be within the allowable range of the pump material (see attached table). The operating temperature for engineering plastic pumps is <60°C, for metal pumps it is <100°C, the suction pressure should not exceed 0.2 MPa, the maximum working pressure is 1.6 MPa, the density should not exceed 1600 kg/m³, and the liquid should be free of hard particles and fibers with a particle size not greater than 30 × 10^-6 m²/s.

5. For media that tend to precipitate and crystallize, it is essential to clean promptly after use and thoroughly drain the accumulated fluid in the pump.

6. After the magnetic drive pump has been running for 100 hours, the bearings and end face rotating rings should be disassembled and inspected for wear, and any worn-out parts that are no longer suitable for use should be replaced.

7. The CQB magnetic pump and internal/external magnetic couplings use high-performance permanent magnet materials, which may pose potential hazards to the following devices. Please maintain a safe distance from these devices when using this series of pumps. Examples include pacemakers, credit cards and other magnetic cards, calculators, computer disks, watches, etc.
