What are the disadvantage of lime slurry pump mechanical seal

lime slurry pump mechanical seal is a primary way to modern pump shaft seal, although the use of it is completely don't leak it is simple, but arrived in minor, probably can bear completely leak amount is completely. But are often present in the lime slurry pump operation and embarrassing situation, then the lime slurry water pump mechanical seal failure reason is what?

1, lime slurry pump machinery seal material selection is not appropriate. Lime slurry pump mechanical seal material are not matched with the transport medium. In the job, the packing element quickly corroded, dissolve or wear and tear, and therefore lose sealing ability. So choose according to the nature of the transport medium and lime slurry pump mechanical seal material is to ensure that the prerequisite for the seal function and normal life.

2, bearing the severe wear or damage to the pump shaft attack serious axial moving, it is also one of the reasons of lime slurry pump mechanical seal leakage. With the development of science and technology, a new method of seal and seal materials present in a row, it will be the pump influences directly the onset of sealing technology and advance.

3, each of the lime slurry pump mechanical seal can withstand the pressure is limited, due to the pressure inside the sealed cavity is calculated, a sealed cavity pressure than the lime slurry pump mechanical seal can withstand the pressure and leak, is one of the common causes of seal failure.

the shortcoming of lime slurry pump mechanical seal performance

produced in the process, the reason of the lime slurry pump and pump mechanical seal leakage has its own cause and external cause, the selection of materials and equipment method and using method of lime slurry pump will cause the failure of mechanical seal, the shortcoming of failure also have differences, to learn through different faults and to make the right judgment promptly can produce supply strong support for practice.

static experiments reveal that: when the lime slurry pump mechanical seal device in the device because workers are not careful, often can make the seal face was damaged so that the deformation and damage, not completely, make the lime slurry pump mechanical seal with granular impurities, may be due to the positioning screw loosening, gland without pressure and machine precision is not high, hypothesis is collar attacks, perhaps is not collar seal compression quantity when installation or is not pressure, also have may be equipment has been damaged.

lime slurry pump mechanical seal of the defect reason and processing: lime slurry water pump and pump mechanical seal including metal non-metallic ring ring corrosion, corrosion and corrosion for sealing ring and corrosion of the contact positions.
