一.Characteristics of vacuum defoaming machine

This type of equipment，Can be made, square, rectangular, circular, with heating function, mixing function.Customizing in general according to the user's requirements。The main characteristic of this device is that it is not deformed and can effectively solve the bubble problem.Please inform us of the type of product, such as concentration, type and quantity. Time requirements

二.Vacuum defoaming machine shopping method.

1.concentration：Different concentration, its preparation is different. Please explain it clearly. Different prices are different.

2.Vacuuming time：If there is any restriction on the vacuum defoaming time, please let us know in advance.

3.yield：Some users directly put the mold to vacuum, which needs to provide mold size, and need to put several molds into the box.If the raw material of the product is directly vacuoled, it is necessary to provide the weight of the product to customize the size.

4.parameter：Each device can go to -0.1mpa，To -0.1mpa, and to remove bubbles is not an idea. Different products can solve the bubble problem in the product with different equipment.

三：Parameters of vacuum defoaming machine

The following table is only a few common specifications. If it is not suitable for production according to the requirements, the preparation is only recommended and can be prepared according to practical application.

四：Installation operation description of vacuum defoaming machine

 1. the equipment includes accessories, box, vacuum pump, pipe, valve, relief valve, vacuum gauge, lock catch and flange.

2. the first step is to place the vacuum pump and vacuum box neatly, and put them in the place where the power supply and operation are convenient.

3. The Air suction valve, vacuum gauge, Pressure relief valve and reserved pipe with Adhesive tape wrapped tightly screwed up, need to use a lot of tape to avoid leakage, such as with flange of the flange is installed on the vacuum pump suction mouth, please.

4. take out the plastic pipe andLock catch, the end of the interface wrapping tape, one end installed on the box, one end installed on the vacuum pump, remember the two ends to tighten, otherwise the air leakage, the vacuum table will not reach -0.1MPA.

5. Install Pressure relief valve. Normal Pressure relief valve is designed at the top. The caliber USES raw tape to tighten and tighten the Pressure relief valve.

6. Install the vacuum gauge, and the operation method is the same, tighten the caliber with Raw tape and install the vacuum gauge at the top.

7.15l vacuum pump and the following extraction rate are air-cooled, 30L vacuum pump and above pumping speed are water-cooled, and need to be cooled by Water, with Water pump.

8. there are two observation windows on the vacuum box. The observation window at the top is used for lighting, and the front observation window is used to observe the internal foam removal.

9. installation of power supply

五：The operation steps of the vacuum defoaming machine

 1. open the vacuum box door and put the product in the vacuum box. If the product is liquid, it is put in the container 2/3.The product will generate more bubbles in the process of removing bubbles. If the container is filled out, the vacuum pump will easily be damaged. The boiling degree of different products is different. At the very beginning, you can slowly test your products.

2. close the vacuum box door after placing the product. Please close it.

3. Closed Pressure relief valve, Turn on the power, open Air suction valve, when the vacuum negative Pressure table to 0.1 MPA products began in the defoaming.

4. there is a design observation window at the top of the vacuum box. Please use flashlight or installation lights to see the internal bubbles.

 5. In the work, if you find that there are many bubbles, you can open the Deflating valve to put some air in, and continue to vacuum out the empty box, and the Deflating valve should not be opened for a long time.

6. after the product is finished, turn off the power supply, open the pressure relief valve, close the exhaust valve, open the vacuum box door and remove the product, and complete the whole process.
