Corrosion-Resistant Rotary Lobe Pump Start-Up And Operation Of The Notes

Corrosion resistant lobe pumps are mainly used for the transport of corrosive liquids. It is one of the more widely used pumps in general equipment pumps. So what matters need to be noted when starting and running the corrosion resistant lobe pump? Today Ace lobe pump's on Lai and everyone to learn together.

I. Pre-launch preparation

1, check the corrosion-resistant lobe pump import and export valves are intact, there is no running blockage, lobe pump and accessories pipeline without leakage.

2, corrosion resistant lobe pump in the start to close the export valve (except for self-priming pumps), not full load, otherwise the rotation torque is too large, the pump will have damage, the motor is also easy to burn due to excessive current.

3、Open the inlet valve, open the exhaust valve to fill the entire pump chamber with liquid, then close the exhaust valve.

4. Determine the steering, point the motor and determine if the steering is correct. Usually the motor is a three-phase, four-wire system. If it reverses, turn any two of the wires against each other, then the motor will form a positive rotation.

II. Up and running

1. Check the fully open valve again and close the spitting line valve.

2, turn on the power, when the corrosion-resistant lobe pump reaches normal speed, and then gradually open the valve on the spitting line, pay attention to close the valve running time should not exceed 5 minutes. Otherwise, the bearing and mechanical seal will be easily damaged.

3. Adjust the working conditions so that the operating conditions are within the range of use in the instructions and as close to the design point as possible. As flow and power are generally not visible, adjust the pressure (outlet pressure inlet pressure = pump head) and current within the rated range.

4、Check the shaft seal condition: mechanical seal: 10 drops/minute, packing seal: 1~2 drops/second, if it exceeds the standard, it should be dealt with in time.

5. Check the vibration and noise conditions.
