Notes On The Use Of Rotary Lobe Pumps For Municipal Sewage Discharge

Municipal sewage discharge using lobe pumps, mainly because the lobe pump import and export pipeline in a line, no go type pipeline, small space requirements, maintenance without moving the pipeline, no special tools, can replace the high-strength protective liner and simple mechanical seal, saving a lot of maintenance costs for customers. So, what do you need to pay attention to during the use of the lobe pump?

1, check the lobe pump and pipeline and the combination of the phenomenon of loose. Rotate the lobe pump by hand and try to see if the lobe pump is flexible.

2. Observe that the oil level should be at the centre line of the oil mark and that the lubricant should be replaced or replenished in time.

3. Tap the motor and try to see if the motor steering is correct. Try to control the flow and head of the lobe pump within the range indicated on the label to ensure that the lobe pump operates at the highest efficiency point in order to obtain the maximum energy saving effect.

4, lobe pump in the process of operation, bearing temperature should not exceed the ambient temperature of 35C, the maximum temperature shall not exceed 80 C. If found that the lobe pump has abnormal sound should immediately stop to check the cause.

5, lobe pump in the first month of work, after 100 hours to replace the lubricant, after each 500 hours, change the oil once.

6、Often adjust the packing gland to ensure that the drip inside the packing chamber is normal (to become a drop leak out as appropriate).

7, the lobe pump in the winter season, after parking, the pump body needs to drain to prevent frost cracking. When the lobe pump is out of use for a long time, the pump should be dismantled, dried, and the rotating part and the combination of grease should be installed and kept properly.
