The vacuum sucks the water from the machine tool to the vacuum pump, how can the water be filtered o

The vacuum sucks the machine into the vacuum pump.

First of all, you need to determine whether the water in the machine is sucked back when the pump is stopped or the water in the machine is sucked away during operation.

If it is during operation, then if you look at why the water is pumped, it must be the liquid level that can be sucked away by the suction port. Why not keep the vacuum pump suction port above the liquid level?

If there is no way to solve the problem of the suction port, then it is OK to add a tank between the vacuum pump and the machine tool Vacuum pump with tank Tank with machine tool.

In this way, the water from the machine falls to the bottom of the tank due to gravity. That won't go into the pump.

If it is a pump stop and suction... Check valve solves the problem.

Add several filter jars between the machine tool and the vacuum pump, the jars are filled with absorbent (such as color-changing silica gel, etc.), and after the air passes through the filter jar, the absorbent in the jar will absorb the moisture in the air.

Add a filter that can be used for negative pressure between the machine tool and the pump, and more than 4 are enough.

What kind of vacuum pump do you use? A vacuum buffer tank can be installed between the vacuum pump and the machine tool, and then an air inlet filter or cold trap can be installed at the air inlet of the vacuum pump.

There is something called a gas-liquid separator that should work, as if it were made of a kind of nanonet

Here's how to use it:

Prepare for the trouble. When using, open the lid of the water tank and inject clean cool water (you can also add water through the drain hose), stop adding water when the water level is about to rise to the water level height behind the water tank, and repeat the start of the machine to no longer add water. After using it for a period of time, it can be refilled with water and water level.

2. Vacuum operation. Tightly attach the suction pipe of the equipment that needs to be evacuated to the suction nozzle of the machine. Turn off the cycle switch, turn on the vertical power supply, turn on the power switch, and start the vacuum operation, and the vacuum degree can be observed through the vacuum gauge corresponding to the suction nozzle.

3. When the machine needs to operate continuously for a long time, the water temperature in the water tank will rise, the water pollution will become worse, and the vacuum degree will be resounded.

4. When it is necessary to provide cooling circulating water for the reaction device, on the basis of the previous operation in Article 3, connect the water inlet and outlet pipes of the device that need to be cooled to the circulating water outlet and water inlet nozzle on the side of the machine respectively, and open the circulating water switch to realize the circulating cooling water.

Summary. Kiss! Hello!

A vacuum pump can drain the water from the pipes. A vacuum pump is used to drain the water (liquid) in the pipe into steam gas and out of the pipe, so that the inside of the pipe can be dried. At one atmospheric pressure, the boiling point (vapor temperature) of water is 100, and when the vacuum pump is used to make the pressure in the tube close to vacuum, its boiling point drops relatively, and when it drops below the outside air temperature, the water in the tube is immediately evaporated.

How much is the negative pressure?

Kiss! Hello! It can reach about 2000 4000 Pa.

It refers to a gas state that is lower than the atmospheric pressure, which is what we often call a "vacuum". For example, when drinking a drink with a tube, there is negative pressure in the head of the tube; The inside of the suction cup used to hang things is also negative pressure. It is precisely because of this pressure difference between the pressure difference and the outside atmosphere that the vacuum pump can "suck" the gas near the suction end in, hoping to help you!

If the vacuum pump (if it is a mechanical pump) is flooded, if the amount of water incoming is not large (less than 2 liters), stop the pump, open the oil valve, and release the water (because the specific weight of the water is below) and open the air shock valve of the mechanical pump for 1 hour.

If a large amount of water is filled into the mechanical pump, drain the oil, add new oil, and open the air shock valve of the mechanical pump for 1 hour.

If the diffusion pump is flooded, it must be removed, the diffusion pump oil must be poured out, the sassafras is dried and polished, cleaned with high-grade gasoline, and new diffusion pump oil must be added.

Check the oil seal ring of the pump shaft, if the wear is serious, it should be replaced with a new part. Leaking water or air in the pipes. It is possible that the nut is not tightened during installation. If the leakage is not serious, cement can be applied to the area of air or water leakage, or cement slurry mixed with asphalt oil.

In this case, if there are conditions, it is best to make the buffer vacuum tank large enough, and the water discharge at full speed you said is not timely, indicating that your original buffer tank design is still not enough capacity, and the bottom should be a negative pump, not an ordinary centrifugal pump. If you can't directly increase the volume of this buffer tank, then you can make another buffer tank in series with it, and place it in a relatively low position as much as possible, so as to increase the volume of the buffer tank. Or simply increase the model of your overcoming pump to increase his pumping capacity.

1.If the power of the centrifugal pump is large enough, a frequency converter can be added, and the control signal is taken from the "liquid level";

2.When the signal of the liquid level and the interlocking (negative) level of the main engine rise to the upper limit, the speed of the main engine will be reduced;

3.It will be better to use DCS to fully control the effect;

Simple controls can achieve the best results;

FYI!

There was no choice but to increase the centrifugal pump. Or change the tank to automatic draining, so that even the centrifugal pump is saved.

Some people say that it is changed to frequency conversion, but in fact, it is still to increase the centrifugal pump.

Increase the vacuum buffer tank, set up a level gauge in the tank, and when the water level arrives, the pump motor stops.
