As shown in fig. 6, being a kind of cleaning method of stage variable pressure pulse cleaner of the application, respectively moisturizing is heated,
Vacuum pulse tank is taken out, and vacuum pulse pumpback and tube chamber internal pulses air-blowing five are most of.First during statement described below, do not have
The system being described to then is considered for closed state.
Process 1, moisturizing:
Moisturizing process is exactly the step of injecting cleaning solution into vacuum tank 2 from water compensating valve 16.It is divided into vacuum feed and normal pressure
Moisturizing both of which can be selected according to actual conditions.Vacuum feed is exactly that vacuum tank 2 is intake under negative pressure state, opens moisturizing
Valve 16 injects cleaning solution into vacuum tank 2 by inlet pipeline, while vacuum pumping valve 6 is opened, and vacuum pump 29 is opened, and is started true
Empty slot vacuuming action makes groove body keep negative pressure (- 80Kpa or so) state.In the case where groove body is negative pressure state, on the outside of inlet valve
Water will accelerate speed and be injected toward rinse bath, and moisturizing efficiency can be improved.Water compensating valve 16 is closed when cleaning solution reaches at high liquid level 11
Stop moisturizing, while being also switched off vacuum pumping valve 6, stops vacuum pump 29.And it opens 8 (3~5 seconds) recovery vacuum tanks 2 of the broken valve of gas and is
Normal pressure state completes entire vacuum feed flow.
The use of normal pressure moisturizing specific method is to open simultaneously the gentle broken valve 8 of water compensating valve 16, (0KPa is left in normal pressure for cleaning solution
It is right) it injects naturally in vacuum tank 2 under state, the gentle broken valve of water compensating valve 16 is closed when cleaning solution reaches the height of high liquid level 11
8, complete moisturizing process.
The cleaning solution of injection needs to submerge article-cleaning, but needs and retain certain altitude at the top of vacuum tank, at this time vacuum tank
According to liquid level be divided under liquid and liquid on.Cleaning solution can be pure water, tap water, softened water, can also add it is various specially
Use cleaning agent.
Process 2, heating：
The step of temperature of 2 cleaning liquid inside of vacuum tank is heated to set temperature.2 cleaning liquid inside of vacuum tank is more than low first
Heater 17, temperature sensor 18 is just allowed to read the real time temperature of cleaning solution, cleaning solution temperature when the height of liquid level 13
Stop heating when at or above set temperature, starts heater 17 when being less than set temperature, cleaning solution temperature is made to stablize
Set temperature or so, heating stepses can be according to the set temperatures of variation through in whole service beat, other steps are not having
Body states heating process.Heater 17 can be the modes such as electrical heating or steam heating, can also be the heating of arbitrary shape
Device.
Process 3, vacuum pulse tank are taken out：
It is exactly cleaning solution by the process that is drawn onto in vacuum tank 2 in vacuum tank 9 that process 3, which is briefly described,.It is as follows：
Moisturizing process 1 and heating process 2 is first carried out, makes the cleaning solution of injection certain altitude in vacuum tank 2, and is heated to
Set temperature.It after having executed process 1 and process 2, opens gas and breaks valve 8, make to keep normal pressure (0KPa) state on 2 liquid of vacuum tank.It opens
Dynamic vacuum pump 29 opens left arteries and veins to 9 pumping high vacuum of vacuum tank after reaching setting time (20 seconds) or setting pressure (- 90KPa)
Rush valve 12 (3-6 seconds), because of the pressure difference of 9 relative vacuum slot of vacuum tank, 2 presence -90KPa or so, according to liquid from high pressure toward low
The principle flowed at pressure, being immersed in the cleaning solution inside the tube chamber instrument in cleaning solution will be inhaled by the vacuum of 2 the inside of vacuum tank
Leading-in device 14 is poured in quickly through left pulse valve 12 in vacuum tank 9, because pressure difference is big, the cleaning solution inside tube chamber instrument is such as arteries and veins
Punching is the same quickly to be injected in very short time in vacuum tank 9, and powerful scouring force is generated in flow process by the dirt inside tube chamber
Stain is taken away, therefore plays efficient cleaning performance.After the opening of left pulse valve 12 reaches setting time, left pulse valve 12 is closed, and
Stop vacuum pump 29, after being delayed 2 seconds, opens the broken valve 7 of tank gas and tank drain valve 28 exhausts the cleaning solution in vacuum tank 9.Arrive this
The left side vacuum pulse tank for completing a flow takes out step.Same principle, after vacuum tank replenishes cleaning solution, in repetition
Stating action, only left pulse valve 12 is changed to right pulse valve 15 then and can similarly complete the right side vacuum pulse tank of a flow and takes out step.
Left side vacuum pulse tank is taken out and vacuum pulse tank pumping in right side is alternately performed, and terminates entire vacuum pulse tank pumping after reaching setting number
Step.
Process 4, vacuum pulse pumpback
It is exactly cleaning solution by flowing back into the process in vacuum tank 2 in vacuum tank 9 that process 4, which is briefly described,.It is as follows：
After process 3 has been first carried out, process 4, vacuum pulse pumpback cleaning can be carried out if selection vacuum tank does not drain
Step.
Specific method is to close the gas connected with vacuum tank 2 to break valve 8, opens vacuum pump 29 and is vacuumized to vacuum tank 2, is reached
To after setting vacuum degree (- 80KPa), then it is delayed 10 seconds.Opening broken pot valve 7 makes vacuum tank 9 keep normal pressure state, as long as beating at this time
Left pulse valve 12 is opened, cleaning solution passes through vacuum suction device under differential pressure action by left pulse valve 12 in vacuum tank 9, then leads to
It crosses interface and is diverted to inside each tube chamber and return in vacuum tank 2, because pressure difference is big flow velocity is fast, therefore has ratio to tube chamber inside
The spot being attached to inside tube chamber is taken away, plays cleaning action by stronger scouring effect.Similarly, if above-mentioned action is by a left side
Pulse valve 12, which is changed to right pulse valve 15 then, can equally complete the right side vacuum pulse tank pumping step of a flow.If executing process
4, then process 3 without tank drain, make cleaning solution between vacuum tank 2 and vacuum tank 9 so process 3 and process 4 can be alternately performed
It washes away back and forth, is not necessarily to additional additional clean liquid, reaches more energy efficient more efficient cleaning purpose.
Process 5, tube chamber internal pulses air-blowing
First, vacuum capping 3 is to be closed, and closes gas and breaks valve 8, makes vacuum tank 2 for closed state.It opens and takes out
Vacuum valve 6 and vacuum pump 29 extract 2 inner air of vacuum tank out.Reach setting time (such as 20 seconds) or setup pressure value (as-
After 90KPa), vacuum pump 29 and vacuum pumping valve 6 are closed.Opening broken pot valve 7 at this time makes vacuum tank 9 keep normal pressure (0KPa), delay
Left pulse valve 12 is opened after 3 seconds.At this time between vacuum tank and vacuum tank there are bigger pressure difference, such as the principle of giant,
Open left pulse valve 12 in a flash, air quickly pours into the cleaning solution squeezed away inside tube chamber instrument inside tube chamber, left pulse valve
It is closed after opening 2 seconds, and opens gas at once and break valve 8, so that vacuum tank 2 is restored normal pressure, normal pressure state down tube intracavitary portion is squeezed away
Cleaning solution backfills rapidly the place occupied by air again, this flowing having a try, which is brought, bigger inside tube chamber washes away effect
It answers, plays the effect in cleaning pipe intracavitary portion.Same principle repeats the above steps, and left pulse valve, which is changed to right pulse valve, can then replace
Execute the tube chamber internal pulses air-blowing step of left and right side.Terminate entire tube chamber internal pulses air-blowing stream after reaching setting number
Journey.
The technical process that entire embodiment 1 is then completed after process 5 is executed, the present embodiment 1 mainly introduces process 1 and arrives work

Set vacuum values are progressivelyed reach, the boiling point that 2 cleaning liquid inside of vacuum tank is generated according to set vacuum values also decreases, vacuum
2 internal liquid of slot starts to roll, after pressure sensor 5 reaches setting value, when being rolled with liquid in system time control vacuum tank 2
Between, open fluid valve 34,1 second~30 seconds under liquid, external atmosphere pressure through tank breaks the liquid that valve 7 sucks vacuum tank 9 with filter 20
On face, keep balancing with ambient pressure, liquid quickly enters jet pipe 1902 in vacuum tank 9, and jet pipe 1902 is at " going out " word
Shape or the cellular bottom for being uniformly fixed on vacuum tank 2, liquid enters vacuum tank 2 through 1902 moment of jet pipe in vacuum tank 9
It is interior, one powerful scouring force is formed, while driving the progress of 2 cleaning liquid inside of vacuum tank is quickly fierce to wash away, when in vacuum tank 2
