Pump water seal
Thread Content
What’s the issue with the pump’s water seal? How does a water seal work? At which part of the pump is water injected, and where does dehydration occur?
Pumps definitely need to be sealed; otherwise, wouldn’t the medium being transported leak out? The water seal of a pump is just one form of sealing, and it can be divided into packing seals, mechanical seals, and dynamic seals. The seal chosen for a pump is related to the hazard level of the medium being transported; the more hazardous the medium, the higher the required seal rating. A water seal works by injecting water into the pump’s seal to create water pressure that provides sealing effect.
Dehydration generally occurs when the water injected serves as a seal, after which it enters the pump and is pumped out along with the other fluid
The so-called \"water seal\" cannot be used alone; it is a type of seal that works in conjunction with a packing seal. Suitable for conditions where the medium contains a high amount of solid particles. Pure water is generally used, with a pressure slightly higher than that of the medium (usually 0.05 MPa higher). The consumption of pure water should be as low as possible, provided that the water seal is maintained. The nozzle can be installed slightly inward in the middle of the packing; its purpose is to prevent solid particles in the medium from entering the packing, thereby avoiding severe wear on the inter-shaft sleeves or shafts and providing protection. Since very little pure water is consumed, the pure water that passes through the filler mixes with the medium and is discharged. These are the ones I have used; I’m not sure if they will be helpful to you.
:lol :lol Learned it*
One of the functions of a water seal is to provide sealing, preventing material leakage； There is also cooling and lubrication of the sealing surface to reduce wear on the shaft. The principle involves a balance between the high-pressure water and the pressure inside the pump; in other words, water is used to push the material that is trying to leak out back into the pump ； It is generally injected into the housing of the pump’s shaft seal, entering the pump directly through the shaft seal and being discharged along with the material.
I have to ask my seniors: what if the water used for sealing does not meet the technical requirements and cannot be mixed into the medium inside the pump? ?
