Description

High-pressure multi-stage ash-water pump flow-through part

Technical Field

The utility model belongs to the water pump field, concretely relates to multistage grey water pump of high pressure crosses class part.

Background

Water pumps are machines that deliver or pressurize a liquid. It transfers the mechanical energy of prime mover or other external energy to liquid to increase the energy of liquid, and is mainly used to transfer liquid including water, oil, acid-base liquid, emulsion, suspoemulsion and liquid metal.

Although the existing high-pressure multi-stage grey water pump overflowing part reduces the friction between particles and the overflowing part by arranging the overflowing groove, the overflowing groove rubs with the particles for a long time, so that the gap of the overflowing groove is easy to be enlarged, and the internal leakage is large.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a multistage grey water pump of high pressure overflows parts, through the interior table wall block fixture block at overflowing the groove to fix the fixture block with overflowing the groove through hidden bolt, the wearability in multiplicable overflow groove prevents that overflow groove and granule from carrying out direct contact, avoids overflowing the groove length time and rubs with the granule, leads to overflow groove clearance grow easily, takes place the big condition of internal leakage.

In order to achieve the above object, the utility model provides a following technical scheme:

the utility model relates to a multistage grey water pump of high pressure crosses current part, including overflowing part body and hidden bolt, the inside that overflows the part body is provided with the impeller, the outward appearance wall of impeller is provided with the blade, the balancing hole has been seted up on the blade, the overflow groove has been seted up to the interior table wall that overflows the part body, the inside block in overflow groove is connected with the fixture block, and the fixture block with overflow the groove and pass through hidden bolt fixed connection.

As an optimized technical scheme of the utility model, the blade is provided with four altogether, and four blades are the annular and distribute.

As an optimal technical scheme of the utility model, overflow groove and fixture block looks adaptation.

As a preferred technical scheme of the utility model, the fixture block is character cut in bas-relief structure, and set up on the fixture block with the screw hole of hidden bolt looks adaptation.

As a preferred technical scheme of the utility model, two have been seted up altogether to the overflow groove, and two overflow grooves are located the both sides inside meter wall of overflowing the part body respectively.

Compared with the prior art, the beneficial effects of the utility model are that:

through the interior table wall block fixture block at overflowing the groove to fix the fixture block with overflowing the groove through hidden bolt, the wearability in multiplicable overflow groove prevents that overflow groove and granule from carrying out direct contact, avoids overflowing the groove long time and rubs with the granule, leads to easily overflowing groove clearance grow, takes place the big condition of internal leakage.
