The reason why the flow of vacuum pump can not reach

When the vacuum pump is in use, the flow rate determines the output. If the flow rate is too small, it can not meet the use requirements, which will seriously affect the use efficiency. So once the flow can not reach the situation we need to find out the reason in time, let's explain it to you.

If the flow of the newly installed vacuum pump fails to reach, first confirm whether the power supply is normal, and whether the reversal caused by the reverse connection of the wire leads to the flow failure, which needs to be eliminated one by one.

The reason why the flow can't be reached is also the wrong selection. Due to the high lift required by the actual working condition and the low lift of the pump, the required requirement can't be met. The vertical height of the on-site outlet pipeline is about 15 meters, and then the horizontal distance is about 1000 meters. After the use, the user's reflected flow can't reach the actual flow only about 60 m3 / h, so the situation can be seen from the above data If the head of the pump is too low, it can be sure that the local flow of the outlet water can not meet the design standard. The horizontal distance of 1000m must be calculated at least according to the head of 20m, so the head of the working condition must be 40-50m sewage pump products to reach the rated flow parameters.

If the flow of the used vacuum pump is not up to the standard, it may be caused by the abrasion and corrosion of the impeller and pump body, or it may be caused by the blockage of the pump body and pipeline. The elimination method is to first confirm whether the pump body and pipeline are blocked, and then check whether the impeller and pump body are worn and corroded, replace the new accessories or select the corrosion-resistant ones The stainless steel vacuum pump product or the self-priming pump product installed on the ground without soaking in water is more suitable. It is also possible that the flow can not be reached due to the loose impeller nut.
