Description
Technical field
The present invention relates to pump valve preparing technical field, and in particular to a kind of Fluorine-lined self priming pump cleaning method.
Background technology
The operation principle of self priming pump is first to fill water in pump case before starting mode of pump, and rotation makes leaf to impeller at a high speed after startup
The current direction volute in conduit is taken turns, at this moment entrance forms vacuum, makes to open into water non-return flap, the air in suction line enters pump
It is interior, and reach outer rim through impeller conduit.Self priming pump category self priming centrifugal pump, it has, and compact-sized, easy to operate, operation is flat
Surely, easy, efficiency high, long lifespan are safeguarded, and has the advantages that stronger suction capacity.Pipeline is not required to install bottom valve, before work only
It need to ensure to contain in the pump housing and quantitatively draw liquid, different liquids can use unlike material self priming pump, continuous with scientific and technological level
Improve, self priming pump uses field also varied, is similar at some in chemical enterprise, due to substantial amounts of soda acid and high corrosion
Liquid need to be conveyed, therefore traditional self priming pump is when in use, it may appear that the problem of corrosion and ageing, the collection of these problems
Middle appearance, cause self priming pump aging occur, damage.
Fluorine-lined self priming pump solves the etching problem of above-mentioned self priming pump in pump valve field at this stage, and Fluorine-lined self priming pump cares for
Name Si Yi is exactly the self priming pump of inner lining fluoroplastics, and the Fluorine-lined self priming pump pump housing uses advanced production technology with metal shell Pian tight liner fluorine
Plastic manufacturing, main flow passage components impeller, pump cover etc. is formed using the disposable hot press moulding of metal insert coated with fluoroplastic, this
The application of kind mode, sufficiently solve the problems, such as self priming pump aging, but certain disadvantage is still had in the use of reality
End.
Fluoroplastics totally still fall within plastic material, its in actual applications, in some specific soda acids and sewage disposal
It is permanent to use when field is applied, can internally form substantial amounts of dirt and greasy dirt, if not in time handle, can be to pump
The space of internal cavity causes necessarily to occupy, and influences the actual operating efficiency of the pump housing, traditional cleaning way, is all to tear the pump housing open
After unloading, cleaned accordingly, not only efficiency is low for this cleaning way, while the effect also unobvious cleaned.
The content of the invention：
The technical problems to be solved by the invention are to provide that a kind of technological process is simple and easy, and cleaning performance is obvious, side
The simple thoroughly Fluorine-lined self priming pump cleaning method of method.
The technical problems to be solved by the invention are realized using following technical scheme：
A kind of Fluorine-lined self priming pump cleaning method, it is characterised in that comprise the following steps：
1) by self priming pump inlet and outlet to be cleaned, UNICOM imports and exports interface in a cyclic water tank, then good seal respectively；
2) water is added in cyclic water tank, self priming pump is then turned on and carries out water circulation, control water is in 25m3/ h high flow rate
Lower circulation 15-25min；This step, water under high pressure conveying, is rinsed for inwall to be existed into bulky grain spot；
3) after above-mentioned water circulation terminates, water in water tank is heated up to 75-78 DEG C, then constant temperature persistent loop 10-
15min；This step is used for after heating so that liner softens, while removes surface portion greasy dirt；
4) keep above-mentioned water temperature constant, the rubble that particle diameter is 1-2mm is added in water, continue water circulation and rinse 25-
35min；The impact of gravel particle, the impact of inner chamber body attachment is realized, is shot down；
5) after the processing of above-mentioned steps 4 terminates, clear water in water tank is cooled to room temperature, and releases clear water, then in water
Acid solution is added in case, again with 25m315-25min is circulated under/h high flow rate；
6) after the processing of above-mentioned steps 5 terminates, internal acid solution is released, alkali lye is then added in water tank, equally with
25m315-25min is circulated under/h high flow rate；
7) after the cleaning of above-mentioned steps 6 terminates, buck is released, then using clear water, has import to be rinsed to outlet using clear water
After 3-5 times, you can.
Acid solution in above-mentioned steps 5 is the aqueous hydrochloric acid solution that concentration is 12-14%；
Alkali lye in above-mentioned steps 6 is the oxalic acid aqueous solution that concentration is 8-12%；
Acid solution and alkali lye in above-mentioned steps 5 and step 6 after use after use, after carrying out filtration treatment, are circulated
Use.
The beneficial effects of the invention are as follows：Cleaning process flow of the present invention is simple and convenient, significant effect, can not dismantle pump
Cause that the spot on pump housing inner lining fluoroplastics is thoroughly cleaned in the case of body, cleaning efficiency is high, quick and safe, cleans cost
It is low, suitable for the surface cleaning of various pump valves.
