3. Scope of application

YQF fluorine lined pipeline pump is suitable for long-term transportation of acid, alkali, oxidant and other corrosive liquids of any concentration under the temperature below 200 ℃. It is widely used in petroleum, chemical industry, metallurgy, power, paper making, flue gas desulfurization, dust removal, food, pharmacy, synthetic fiber and other industries.

4. Product Features

(1) The pump is a vertical structure with the same inlet and outlet diameters and located on the same centerline. If a protective cover is added, it can be used outdoors.

(2) The impeller is directly installed on the motor shaft, which can effectively balance the radial and axial loads generated by the pump operation, thus ensuring the operation balance of the pump and reducing the noise.

(3) The bearing adopts ordinary and particle resistant mechanical seal, which is corrosion resistant and wear-resistant, effectively increasing the service life of mechanical seal.

(4) The series and parallel operation mode of pumps can be adopted according to the use requirements, i.e. the flow and head.

7. Installation method

(1) The pump shall be installed and fixed on a stable foundation. It is better to lay a cushion between the base and the foundation. Ensure that the pump will not affect the vibration of the pipeline when it is started. The pump is not affected by other mechanical vibration.

(2) When installing the pipeline, it shall be noted that the inlet and outlet pipelines of the pump shall not exert force on the pump and shall be equipped with corresponding supports.

(3) Valves shall be installed on the inlet and outlet pipelines of the pump when the pump is installed under the condition of reverse flow, and it is better to install pipeline compensator. When the pump is under suction working condition, it is required to install valves at the inlet and outlet of the pump.

(4) Check whether the rotating parts of the pump are stuck or collided. If the pump is collided during transportation, check whether the coupling is concentric and adjust it.

(5) Sufficient maintenance space shall be reserved for the pump during installation to facilitate equipment maintenance in the later period.

8. Precautions

(1) Before use, the pump shall be filled with enough liquid. It is strictly forbidden to start the pump when there is no liquid or insufficient liquid.

(2) Turn on the power supply, click the start switch first to see whether the running direction of the motor is consistent with the rotation direction of the pump. If not, correct it immediately, and do not reverse it.

(3) The unit operates for 5-10 minutes. If there is no abnormal phenomenon, it can be put into operation.

(4) During shutdown, the outlet valve shall be closed first, and then the power supply shall be cut off.

9. Frequently Asked Questions

(1) The reason why the water pump does not discharge water may be that there is air in the pump chamber, the suction head is too high or the suction pipe is too long.

(2) Insufficient pump flow may be caused by partial blockage of pipes and impeller of pump flow passage, insufficient valve opening, etc.

(3) Excessive pump power may be used beyond the rated flow.

(4) Noise and vibration may be caused by unstable pipeline support, gas mixed with liquid, bearing damage, etc.

(5) Pump leakage may be caused by mechanical seal damage or loose connecting bolts.

10. Use needs

(1) For pumps with high lift, check valves shall be installed on the outlet pipeline to prevent water hammer damage caused by sudden shutdown.

(2) If cavitation occurs when the pump is running, it must be stopped within 1 minute.

(3) When the pump is shut down for a long time, the inner flow passage of the pump shall be cleaned.

(4) If the power is cut off suddenly when the pump is running, the power must be turned off immediately and the outlet valve must be closed.

(5) The noise of the pump is ≤ 95dB. In case of vibration and noise, the pump should be shut down for inspection and troubleshooting before operation
