The working principle of the professional cleaning machine for micro autoclave|The working principle of the professional cleaning machine for micro autoclave

 

        experimental instrument limited production of micro high-pressure reaction kettle professional cleaning machine working principle is what kind of?

        below are the main steps and procedures for the work of ultrasonic cleaning machine, as well as the principle and knowledge of ultrasonic cleaning machine work. The principle of ultrasonic cleaning machine is mainly the power ultrasonic transducer, frequency source energy, and converted to mechanical vibration, by cleaning groove wall the cleaning fluid in the channel to the ultrasonic radiation. Due to the radiation of the ultrasonic wave, so that the liquid in the groove of the micro bubbles in the sound wave of   to keep the vibration. When the sound pressure or sound pressure to a certain extent by the pressure, the bubble will quickly expand, and then suddenly closed. In this process, the bubble closing instant shock wave, the bubble around   1012-1013pa pressure and the Bureau of regulation, such tremendous pressure generated by the ultrasonic cavitation can destroy the insoluble dirt and make their differentiation in solution, the steam type cavitation directly impact on fouling repeatedly. On the one hand and destroy the dirt cleaning a surface, on the other hand can cause fatigue damage and dirt layer was transferred from the gas bubble type, vibration scrubbing on solid surface pollution layer once the seam drill, drill into the   bubble immediately; vibration makes the dirty layer off, due to cavitation, two the liquid in the interface rapidly dispersed and emulsified oil, when the solid particles wrapped and adhered to the surface cleaning, oil emulsion, solid particles to fall off, in the ultrasonic cleaning   liquid transmission will produce positive and negative alternating pressure, jet formation, impact cleaning, and because the nonlinear effect will produce acoustic flow and the micro acoustic streaming, and ultrasonic cavitation will produce high-speed micro jets in the solid and liquid interface, all the   some effect, can destroy the dirt, remove or weaken the boundary pollution layer, increasing the stirring and diffusion Use, accelerate the dissolution of soluble dirt, and strengthen the cleaning effect of chemical cleaning agent. Thus, any liquid can be dipped into the sound field and the presence of   the place has a cleaning effect, the characteristics of the surface is suitable for the shape of a very complex parts of the cleaning. In particular, the use of this technology, can reduce the amount of chemical solvents, thereby greatly reducing the environmental pollution.

Catalyzer|Catalyzer

according to the International Union of pure and Applied Chemistry (IUPAC) 1981 definition: the catalyst is a change in the reaction rate but does not change the

;  

reaction of the total standard Gibbs free energy of the material.

; &nbspThe effect of

catalyst in chemical reaction is called catalysis. The catalyst in the industry also known as catalyst.

; &nbspThe composition, chemical properties and mass of

catalyst are not changed before and after the reaction; the relationship between the catalyst and the reaction system is the same as the relationship between the lock and key, which is highly selective (or specific). A catalyst does not have catalytic effect on all chemical reactions, such as manganese dioxide has played a catalytic role in heat decomposition of potassium chlorate, accelerate the reaction rate, but on the other chemical reactions would not have catalytic effect. Certain chemical reactions are not only the only catalyst, such as the decomposition of potassium acid in the heat can play a catalytic role as well as Magnesium Oxide, iron oxide and copper oxide and so on.

; &nbspThe definition of

junior high school textbook: can change in chemical reaction (speeding up or slowing down) the rate of chemical reaction of other substances, and that the quality and the chemical properties of itself after reaction (change reaction) did not change the substance called catalyst, also called catalyst. The physical properties may change, for example, the MnO2 in the catalytic reaction of potassium chloride to produce potassium chloride and oxygen from the mass into powder before and after the reaction.   there is a saying, the chemical reactions involved in the catalyst, a first reactant and reaction product, then the two continue new chemical reactions in the original condition, and the reaction conditions of the reaction conditions the resultant catalyst is the original reactant change. For example:  

to H2O2 solution with the addition of FeCl3 solution, the following reactions can occur:

; &nbspH2O2+2Fe3+==2Fe2+ 

; +O2  +2H+  H2O2+2Fe2++2H+==2Fe3++2H2O 

can see that the first reaction to generate the +2H+; 2Fe2+  in the second reaction immediately after the reaction, and changed back to 2Fe3+, and the first reaction is just offset. Here Fe3+ will play a catalytic role.

; &nbspKClO3

oxygen to join the MnO2, the following reactions can occur:

;  

2KClO3+2MnO2== 2KMnO4+Cl2 +O2 2KMNnO4== heating, heating K2MnO4+MnO2+O2, K2MnO4+Cl2== 2KCl+Mno2+O2  

heating;The substance produced by the chemical reaction of the

catalyst will be re generated in the following reaction, namely, the original catalyst.

Each

1. into the reaction medium, the kettle body should not exceed 2/3 level, cast material with a soft cloth to wipe clean the sealing surface, careful not to rub scratches, sealing surface, installed on the kettle cover a main bolt when not overexert, shall not exceed the prescribed tightening torque range of 80~120N.M; and according to the diagonal distribution principle. Tighten the bolts evenly, tighten the 2~3 times, in order to prevent the collapse of the sealing surface. The kettle cover is provided with two high pressure needle valves, one is an exhaust valve, one is a sampling valve (or an air inlet), the needle type valve is sealed, and the needle is provided with a needle.

2. connected to the power, open the speed switch, speed began to show, open the temperature switch, the temperature began to show, set the required temperature, heating, rotary speed control knob set speed.

3.: we set the temperature according to the "select addition and subtraction set the temperature control accuracy is not ideal, such as the need to self tuning, according to the key of self-tuning, self first set the temperature to be used to control the temperature, the key for five seconds, then the digital temperature control instrument down the lower right corner of the display lamp flicker can let go, to go through three meter to the end of the heating and cooling, until the display lights stop flashing after self tuning over, then the normal temperature will be controlled at 1 DEG C, ± self tuning process if you want to quit, hold the button for five seconds, until the indicator lamp is exit. The auto tuning process can not guard, but not to do self tuning during the experiment, can not change the setting temperature, because your appearance in the dark condition, the temperature exceeds the set temperature, so as not to damage the sample unnecessary trouble.

4. knob speed: motor speed through the speed control knob to adjust the speed, clockwise rotation is the speed of the large, counter clockwise is small.

5. each time after lowering the main nut with wrench symmetry test, open the tank cover, remove the samples, cleaning with the corresponding cleaning medium, reaction kettle, don’t touch, scratch the sealing surface, the dirt on the sealing surface, to the corresponding cleaning medium, and dry with a soft cloth net.

6  safety valve series bursting disc safety valve, the factory has been adjusted, is strictly prohibited to mobilize.
