Abstract
The invention discloses a method for cleaning deposits of a water-ring vacuum pump. The method includes operation steps of disassembling the water-ring vacuum pump, soaking deposit positions of the water-ring vacuum pump by 8-10% hydrochloric acid solution, allowing the water-ring vacuum pump to stand for 20-30 minutes, then soaking the deposit positions of the water-ring vacuum pump by 10-12% hydrochloric acid solution, allowing the water-ring vacuum pump to stand for 60-90 minutes, purging the deposits of the water-ring vacuum pump by compressed air under the pressure of 0.8-1MPa for 10-15 minutes and allowing the water-ring vacuum pump to stand for 20-30 minutes; starting a high-pressure cleaning machine, regulating the pressure until the pressure is 8-10MPa, aligning a gun head of the cleaning machine with the deposit positions, stepping a pressure transmitter and cleaning the deposits for 5-10 minutes. According to the technical scheme, the method has the advantages that the deposits of the water-ring vacuum pump can be effectively removed, a pump body is prevented from being damaged owing to the fact that the method is specifically used for cleaning the deposit positions, and the method can be widely applied to removing deposits of water-ring vacuum pumps.
Description
Technical field
The present invention relates to Calcium Carbonate Filtration machine Nash hytor fouling cleaning method.
Background technique
In service at first phase phosphogypsum ammonium sulfate device processed, due to Nash hytor serious scale, causes Calcium Carbonate Filtration operation to occur that degree of vacuum does not reach the problem that requires; And the method for traditional scale removal is by acid soak, still, easy etching apparatus during this method misoperation, causes unnecessary equipment damage, affects the working life of equipment.
Summary of the invention
For the deficiencies in the prior art part, the present invention aims to provide a kind of cleaning method of Nash hytor fouling, guarantees, in removing the process of fouling, can not damage the pump housing.
The technical solution used in the present invention: a kind of cleaning method of Nash hytor fouling, comprises following operating procedure:
(1) Nash hytor is taken apart, adopt 8-10% hydrochloric acid solution to infiltrate Nash hytor fouling place, place Nash hytor after 20-30 minutes, use again 10-12% hydrochloric acid solution to infiltrate Nash hytor fouling place, place Nash hytor after 60-90 minutes, adopt the pressurized air of 0.8-1MPa to purge Nash hytor fouling 10-15 minutes, then Nash hytor is placed 20-30 minutes;
(2) start jetting machine, pressure is adjusted to 8-10MPa, with cleaning machine gun head, aim at fouling place, step on the cleaning of kinetic pressure transmitter, clear up 5-10 minutes.
Adopt technique scheme, can effectively remove Nash hytor fouling, by reality, be used and shown, removal effect is good, in removal process, although use hydrochloric acid solution to infiltrate, subsequent handling adopts high pressure water washing, can not leave over acid solution, and while infiltrating hydrochloric acid solution, just, for fouling place, can not damage the pump housing like this, it can be widely used in the scale removal of Nash hytor.
Embodiment
A cleaning method for Nash hytor fouling, comprises following operating procedure:
(1) pump cover of the Nash hytor in a Calcium Carbonate Filtration operation is taken apart, take again the cleaning eye of Nash hytor apart, as the cleaning eye of rotatingshaft both sides, the newly-increased cleaning eye of turnover gas, rubber ball hole, observe the foulant of pump inside, adopt 8% hydrochloric acid solution to infiltrate Nash hytor fouling place, can infiltrate fouling place with the cotton yarn that soaks hydrochloric acid, place Nash hytor after 20 minutes, with 10% hydrochloric acid solution, infiltrate Nash hytor fouling place again, fouling is under hydrochloric acid solution infiltration Bubble formation, placing ring type vacuum pump put after 70 minutes, adopt the pressurized air of 1MPa to purge Nash hytor fouling 10 minutes, then Nash hytor is placed 20 minutes, find that fouling part is loosening,
(2) start jetting machine, pressure is adjusted to 10MPa, with cleaning machine gun head, aim at fouling place, step on the cleaning of kinetic pressure transmitter, clear up 8 minutes, dirty piece is under the active force of high pressure water, and dirty piece is broken to depart from, again dirty piece is cleared out outside pump, can complete cleaning, load onto pump cover and can use.
Claims (1)
1. a cleaning method for Nash hytor fouling, is characterized in that comprising following operating procedure:
(1) Nash hytor is taken apart, adopt 8-10% hydrochloric acid solution to infiltrate Nash hytor fouling place, place Nash hytor after 20-30 minutes, use again 10-12% hydrochloric acid solution to infiltrate Nash hytor fouling place, place Nash hytor after 60-90 minutes, adopt the pressurized air of 0.8-1MPa to purge Nash hytor fouling 10-15 minutes, then Nash hytor is placed 20-30 minutes;
(2) start jetting machine, pressure is adjusted to 8-10MPa, with cleaning machine gun head, aim at fouling place, step on the cleaning of kinetic pressure transmitter, clear up 5-10 minutes.
