The Reason Of Leakage In Vertical Pump？
TIME：2024-06-03 Author：admin Views：
Acid and alkali resistant vertical pump is a kind of vertical centrifugal pump which is injection molded with engineering plastics PP/PVDF, it has the characteristics of acid and alkali corrosion resistance, oxidation resistance, and can be idled without water.
It is mostly used in the field of waste gas treatment in the waste gas tower, painting, biological deodorization, acid washing, printing and dyeing, circuit board, electronic industry and many other fields. Mabel environmental protection for you to share the acid and alkali resistant pump vertical pump in the use of water leakage in the process of what are the causes of? Vertical pump leakage causes can be analyzed from these aspects: boot leakage, shutdown leakage.
The reason of water leakage at start-up
● The voltage is too low.
● Impeller damage or wear.
● Inside the pump body or inlet pipe screen is clogged with debris and stones.
● The export pipeline is installed too many elbows.
● Acid and alkali vertical pump suction range is too high or suction pipeline is too long.
● Acid and alkali vertical pump assembly process rubber seal O ring, not installed, or fastened too tight, resulting in deformation of the rubber ring damage without sealing effect, vertical pump installed on the boot leakage.
● The vertical pump installation height is too low, the liquid level is more than 2/3 of the subject, the liquid from the overflow hole.
● The mechanical seal appears to wear.
● There is air leakage in the suction line.
The reason of water leakage at shut down
● Acid and alkali resistant vertical pump conveying liquid height is relatively high, when the shutdown, there is a lot of liquid backflow in the pipeline, resulting in a sharp rise in liquid level, then the liquid out of the overflow hole.
The solution to vertical pump leakage
● Adjust the voltage.
● Replace the new impeller.
● Check and clean out the blockage.
● There are too many pipes in the shape of N. It is recommended to install automatic exhaust valve at the higher point.
● Lower the suction range or shorten the pipeline.
● Acid and alkali vertical pump assembly process to install rubber seal O ring, do not tighten too tight!
● Acid and alkali vertical pump in the assembly process, diagonal fastening screws.
● The liquid level needs to exceed the height of the impeller, not more than 2/3 of the subject, to enhance the installation height of the vertical pump.
● Adjust the seal friction position, take out the seal, and then exchange the orientation of the device, such as the seal on the fastening spring loss of elasticity or cracking, you can remove the spring, with the appropriate diameter of the steel wire or wire tie.
● Eliminate pipeline air leakage phenomenon, within the permissible suction range check method pump start 4-5 minutes of water has not been sucked up, please use your ear close to the inlet pipeline suspected leakage place to listen to the sound of suction, or in the suspected leakage place coating white latex and other methods to repair.
● Conveying the liquid height is relatively high, it need to be installed a check valve at the outlet.
