Grade, the common acidic leach material easily purchased in market, in use will not to human body generate toxic side effect, will not be to by scale removal
Corrosiveness is generated inside water heater, is continued normally as long as scale removal finishes to be cleaned inside a water cavity and pipeline with clear water
Use water heater.
Interface accessory：Generally there are the inside and outside connector of stainless steel, the double end loose joint stainless steel of various 4 points of bores to 6 points of bores
Heatproof hose, raw material band, rubber cushion etc..
2nd, the dismounting of the intake-outlet connector, sewage draining exit of water heater：It is general conventionally to dismantle corresponding interface
It is to learn and grasp the installation method and method for dismounting of water supply pipe joint to the requirement for using the operator of scaler most basic
Basic common sense.
3rd, according to specific water heater type to be cleaned, the solution efferent duct 6 of corresponding type species and return duct 7 are carried out
Connection.
Have herein a little it is important to note that when dismantle Domestic water storage formula electric heater sewage draining exit when, due to hot water
The substantial amounts of hot water of device internal reservoir before the incrustation scale of this water heater is removed, has to client is allowed in advance one evening to stop
The heating function of water heater and closing power supply, make its water temperature inside avoid the scald of personnel below 30 DEG C；It to be put on during dismounting
Raincoat gets clothes wet largely to sluice suddenly when preventing discharge outlet plug or magnesium stick from screwing out.
4th, after connecting efferent duct 6 and return duct 7, poured into acid solution bucket 1 tap water according to the difference of type come
The water of decision water, in general, the water consumption to gas heater and instant electric water heater's scale removal are minimum to need to use
13-15L water；It is medium to the light-receiving glass pipe scale removal water consumption of Domestic water storage formula electric heater and solar water heater to use 40-
60L water；To solar water heater water-storage bucket scale removal water consumption maximum demand 60-80L water.
5th, plug in plug, closes total earth leakage circuit-breaker, be first turned on pump switch 5 allow water pump (4 start running,
Balance is kept since the position of solution tank water outlet is slightly above electric heating tube 2 in the Inlet and outlet water of solution tank 1, without worrying electrical heating
The heater switch 3 that electric heating tube 2 could be opened after the meeting dry combustion method of pipe 2 carries out the heating of solution, the mechanical temperature control of installation casing
Switch control handle is set to 85-90 DEG C；At this moment, the corresponding equivalent lemon granulates by calculating can be put into simultaneously, generally
Control the lemon granulates that 40-60g is added in every liter of water.In this course, it should be noted that the SEA LEVEL VARIATION of observation solution tank 1,
The size for adjusting backflow water yield at any time avoids that solution tank 1 is made to overflow the waste for causing dissolving acid solution and shadow due to backflow water yield is excessive
Ring scale removal effect.
6th, being gradually increasing with water temperature, the Citric Acid Mono particle in solution tank 1 can all dissolve molten into being circulated in
Liquid bucket 1 and water heater corresponding pipeline and participate in dissolving incrustation scale work in.When the Citric Acid Mono particle at 1 bottom of solution tank is whole
After dissolving, the acidity carried out to acid solution every half an hour with ready pH value test paper before detects, because with heat
The dissolving of incrustation scale inside hydrophone, effective dissolving substance, that is, Citric Acid Mono particle contained by acid solution can be gradually used up, dissolved
Ability also can be with reduction, so operating personnel should periodically be monitored the effect and effect of acid solution.
Pay attention to：PH value is that numerical value is smaller to represent acid stronger, the Citric Acid Mono particle of the water addition of isodose in 1-7
Dosage is bigger, and acid solution is higher with regard to concentration, stronger to the solvability of incrustation scale；The acid solution water temperature of heating is higher simultaneously,
It is also stronger to the solvability of incrustation scale.
In use, a test-strips of tearing from test paper sheet, are clamped with hand or pincette and are immersed in solution tank 1, observation
Its color change, then take up vitta corresponding in standard color comparison card and relatively determine the pH value of solution.It is known that
The acidity of current solution, pH value is smaller, acid stronger.
Illustrate in acid solution citric acid when the pH value for detecting acid solution is reduced to 6.5-7 by substantially depleted,
At this moment with reference to the service life of the water heater work is completed to decide whether to stop scale removal process.In general, usage time
Water heater below 5 years, incrustation scale are not to accumulate very thick, can remove and finish by the scale removal time of 2-3h；It at this point, can
To terminate the scale removal of water heater work.
If usage time is the water heater of 5 years or more, the heating tube 2 that can first stop solution tank 1 heats, return duct
Outer comb after 7 reflux discharging valve 11 is put at the sewage draining exit of toilet, and opening reflux discharging valve 11 allows inside water heater
Useless acid solution is discharged into municipal drainage.
The acid pickle of the water heater it is drained after, closing volume discharging valve 11 is opened recycle control valve 10, is started against
Circulation canal；The step of repeating to add water and add in lemon granulates, and the work of cycle dissolving incrustation scale is carried out again.
From the point of view of the waste liquid color contrast of scale removal is dissolved twice, the waste liquid color of general first time is just as dense rice washing water
The same milky turbidity liquid is simultaneously granular with thick incrustation scale, secondary waste liquid color be inclined brown it is somewhat muddy this
When can see that electric heating tube 2 in solution tank 1.
7th, when completing above-mentioned scale removal work, discharging of waste liquid it is complete after, continue from 1 continuous injected clear water of solution tank, allow water
Pump 4, which is pumped into clear water inside water heater, carries out cleaning remaining waste work；To then storage-type electric water heater, preferably clear water
Again to externally discharged waste water after filling it up with.
After the water of blow-off pipe outflow has become clarification, close power supply and stop water pump 4, remove the efferent duct of scaler
6 and return duct 7, taking back the original corresponding water-system pipeline of water heater again can.
