Press filter feeding pump of pump barrel cease to function

the feeding pump of pressure filter of pump barrel why stop working?

the structure of the pump: general pump in the structure without any grit wiper, pump in the process of reciprocating motion, make sand settlement directly to the plunger and pump barrel, space and fortress of sand control pump column slot only with grit and sand function, also poses a pump cylinder wear. Plunger and pump barrel surface treatment and selection of materials, the plunger and pump barrel surface material and the conflict between sand coefficient can also affect the sand will card in the plunger and pump barrel gap.

affect the feeding water pump of pressure filter filtration velocity of several factors:

the feeding pressure: pressure filter feeding pump work assignments, into the supply equipment filter feeding pump of pressure so that influence filtration velocity is into the material feeding pressure of pump.

feeding ash: filling slurry ash content of the choice of the filling pulp viscosity, filtration velocity into material pulp viscosity choices;

feed pulp density: solid content high, the pulp density is high, filter cake formation speed will be slow.

low feeding pulp density: filter cake formation will be fast, so visible slurry concentration had a great influence on filter cake moisture content.

no matter what mechanical equipment, in order to ensure the normal work and extension of its using life, we are all necessary for its excellent service and protection. Punctual equipment is it necessary to pack a, then press filter feeding pump equipment how to correct to pick up it?

1, when the feeding pump of pressure filter equipment stop work, we in addition to the closed power supply, we also need to filter through the area tidy up clean, if be due to packing pressure filter feeding pump unit, and the damage to equipment, that is penny wise and pound foolish.

2, when the filtrate was feed pump twitched into equipment, so want to tidy up the filter chamber, is equivalent to tidy up filter plate, prevent filtrate in these crucial bearing dry accumulation, jams, damage to filter plate structure, make the feeding pump of pressure filter equipment can't normal operation.

3, in addition to clean filter chamber, we need to pick up the filter cloth. Filter press filter cloth feeding pump is directly guide device between solid and liquid separation, when cleaning to prevent filter cloth drape, ensure no jam Ming flow feed opening, and return empty undercurrent, ensure smooth feeding pump of pressure filter.
