Slag pump sealing method

There are three types of sealing methods for slurry pumps, each of which is different. Here are three types of sealing methods.

Slurry pump is the most common kind of seal, which is the first type of seal. It is used to inject water into the shaft seal and continuously inject certain pressure water into the packing to prevent the pump body from discharging in vitro. It is not suitable for the impeller seal. Multi-stage tandem pump with packing shaft seal. Filler shaft seals are simple in structure, easy to maintain and inexpensive.

The slurry pump is followed by the impeller seal, which is driven by a centrifugal force of a reverse centrifugal force to prevent leakage of the slurry. In the case that the positive pressure at the pump inlet is not more than 10% of the pressure at the outlet of the pump, the first-stage pump or the first-stage pump of the multi-stage tandem pump may adopt an impeller-filled shaft seal, and the impeller shaft seal may have no shaft-sealing water and may not be diluted. Body, good sealing effect. Therefore, in the case where dilution is not allowed in the slurry, such a seal can be considered.

Again, mechanical seals are generally used where sealing requirements are high. In particular, some chemical and food industries require not only sealing, but most importantly they are not allowed to add extra components into the pump body. The disadvantages are high costs and difficult maintenance.
