Description

Desulfurization waste water delivery pump machine seals collection dress formula washing unit

Technical Field

The utility model relates to a water pump technical field especially relates to desulfurization waste water delivery pump machine seals collection dress formula washing unit.

Background

The water pump is a machine for conveying liquid or pressurizing liquid, and it can transfer the mechanical energy of prime mover or other external energy to the liquid to increase the energy of liquid, and is mainly used for conveying liquid including water, oil, acid-base liquid, emulsion, suspoemulsion and liquid metal, etc.

The medium that the water pump carried contains a large amount of particulate matters and permeates to mechanical seal face, leads to sealed face rapid wear and tear to generate heat, causes the sealed damage of machine seal, causes the water pump to leak, and the hard ring of water pump machine seal is worn and torn, is the circumference slot of concentric distribution, has a large amount of particulate matters deposits simultaneously on mechanical O-shaped ring. Therefore, the desulfurization waste water conveying pump machine enclosed container type flushing device is provided.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the defects existing in the prior art and providing a desulfurization waste water delivery pump machine sealing and packaging type flushing device.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

desulfurization waste water delivery pump machine seals collection dress formula washing unit, including machine seal shell, machine seal gland and washing unit, install machine seal gland on the machine seal shell, install on the machine seal shell and wash the unit.

Furthermore, a mechanical seal cavity is arranged inside the mechanical seal shell, and a mechanical seal shaft sleeve is arranged inside the mechanical seal cavity.

Furthermore, an O-shaped ring is installed on the mechanical seal shaft sleeve, an end cover is installed on the mechanical seal shaft sleeve, and threaded holes are symmetrically formed in the end cover.

Furthermore, the washing component comprises two groups of connecting rings, a water inlet pipe and a water outlet pipe, the two groups of connecting rings are symmetrically arranged on the machine seal shell, and the connecting ring pipe penetrates through the machine seal shell to extend towards the inner part, and the inside of the connecting rings is a cavity.

Furthermore, a water inlet pipe is arranged on one group of the connecting rings, and a water outlet pipe is arranged on the other group of the connecting rings.

The utility model has the advantages that:

1. through the arranged flushing assembly, water is conveyed to the interior of the mechanical seal through the water inlet pipe, the flushing assembly flushes particles attached to the end face of the mechanical seal, and then the flushed particles are discharged through the water outlet pipe, so that the O-shaped ring is prevented from being abraded by solid particles in water, the loss of the O-shaped ring is reduced, the sealing effect is increased, and meanwhile, the mechanical seal is cooled; the problem of machine seal abrasion is fundamentally solved, and the using effect is very good.
