What are the differences in the normal positive pressure conveying and how to solve them

What is the meaning of the normal occurrence of forward output, and how to solve it? I think there are some anomalies in the normal positive pressure output. It's the right way to solve it according to that um.

The positive pressure output is normal, if there is some abnormality, then see what the abnormality looks like? Case-by-case analysis.

There will definitely be times when the lawsuit won't be solved, and the solution is to find the place where the delivery can't go and fix him.

Although it is a common occurrence of pages in middle school, how to solve it? It's good that you can find out how to fix it.

If there is an abnormality in the normal operation of the suppression and transportation, first of all, you must stop their operation, stop the operation, and then check that one of their processes is the first problem.

I'm going to sue for those abnormalities that appear in chilblains, whether it can be resolved, and your situation is pressurized, and the lawsuit position can be adjusted to adjust their pressure to address the cause of this failure.

It is very easy to deliver the voltage normally, as long as there is voltage at both ends, the current output can be completed.

If there is any abnormality, you can go directly out of the business and open it directly.

If there is an exception, you can check it again.

If you want to know what abnormalities occur in the normal positive pressure delivery, this is talking about voltage. This is often sometimes the power line is not good, and a lot of electricity will be wasted on the road. The output voltage is quite low when it comes to people's homes, so we can use transformers.

If there is an abnormality, then be sure to close the power switch and find the problem.

This is to be adjusted according to the marker.

If there is an abnormality in the normal positive pressure, if you want to solve it, you can directly solve it according to the fault.

Xu Ya's loss is not comparable from the bridge.

Positive pressure conveying is to use the front end of the conveying system, that is, the fan at the beginning of the system to introduce compressed air into the conveying pipeline, and use the pressure difference between the beginning and end of the pipeline to make the air flow in the pipeline and drive the movement of materials. In the positive pressure conveying system, the material is fed into the conveying system by the feeding device, and at the end of the conveying, the material is separated from the air.

It's normal for Android to have this kind of problem occasionally.,Affect your use.,If it's very serious, redo the system.,It's not serious, just make do with it.。

The common problem of Android phones, there is no special effect, and it will be used.

File corruption bar, re-next.

It is recommended that you reflash the system.

Positive pressure is a gas state in which the pressure of a gas is higher than that of a normal pressure.

Negative pressure is a state of gas pressure that is lower than normal pressure.

Connection: Positive pressure and negative pressure are opposites.

Differences: 1. Different functions.

Positive pressure is a state of gas that is higher than the pressure of a gas at normal pressure (i.e., one atmosphere). For example, when inflating a bicycle or car tire, positive pressure is generated at the outlet end of the pump or pump.

Negative pressure is the state of gas pressure below normal pressure (i.e., one atmosphere).

2. The application is different.

The use of positive pressure is usually involved in the industry, especially in the selection of micro pumps (such as micro booster pumps, micro air pumps, micro pumping pumps, micro gas circulation pumps, micro pumping pumps, micro inflatable pumps, etc.).

The use of negative pressure is very common, and people often make a certain part of the space appear in a negative pressure state, so that they can take advantage of the ubiquitous atmospheric pressure replacement effect.

3. The conveying power is different.

The test and theoretical calculation results show that the positive pressure conveying power is 4 3 times that of the negative pressure conveying power, and the positive pressure conveying gas not only shortens the gas conveying time, but also ensures that the gas concentration remains unchanged. The data measured by the positive pressure tube can truly reflect the natural ignition state of coal.

It's like a room where it's under positive pressure, and the air in the room is going outward"Leaks", and when there is negative pressure, the outside air will be sent into the room"Irrigation"The so-called positive and negative pressures are relative to a reference! Generally, we will take the atmospheric pressure as a reference, and the positive pressure higher than it is called negative pressure, and the positive pressure lower than it is called negative pressure!

If you are in the event of a fire, if you can't escape, it's best to stay in a room under positive pressure!

The positive pressure system generally refers to the positive pressure conveying system, and the negative pressure system generally refers to the negative pressure suction system.

The positive pressure conveying system consists of a compressed gas generator, a transmitter, a pipeline, a booster, a receiving silo, a filter and a controller.

When the positive pressure conveying system conveys the material, the air flow is generated by pressurizing the transmitter, and the pressure generated by the air flow pushes the material to move vertically or horizontally in the pipeline. As shown below. The material is transported from the transmitter to the receiving bin through the pipeline, and at the same time the gas and the material are separated by the filter, the material remains in the silo, and the gas is discharged into the atmosphere through the filter.

The controller controls each part of the feeder to work in the set order. The suitable forms of materials for positive pressure conveying are: embolic conveying, dense phase conveying and dilute phase conveying.

The negative pressure suction system is mainly composed of vacuum suction station, suction pipeline, gas terminal connector, etc.

According to the principle of atmospheric balance, the fresh air outside is directly introduced into the room through the wall air inlet or window air inlet, so that the indoor air is fresh and clean. The fresh air host is installed in the ceiling of the bathroom or kitchen, and the indoor dirty air is sucked into the host through each exhaust outlet and strongly discharged outside, and the indoor air naturally forms a negative pressure area, and the negative pressure effect is used to let the outdoor fresh air filter through the vent and automatically enter the room, forming an uninterrupted and continuous circulation of exhaust and inlet air.

The positive pressure system means that the pressure of the conveyed working fluid is greater than the atmospheric pressure, and the negative pressure system means that the pressure of the conveyed working fluid is less than the atmospheric pressure.

There are generally several reasons why the pump pressure does not go up, one is that there is a leakage point, this check is to open the pump at a flow rate of 1ml min, carefully check the leakage point, and the mobile phase is used with a mobile phase with too small viscosity, for example, sometimes when using a high concentration of n-hexane, it is difficult for the pump to pump it up, at this time, you can use other solvents with a higher viscosity such as ethanol to mix in a certain proportion, so that it can be normal, and there is a problem with the pump itself, which may be a piston scratch, And the active input valve is abnormal and other reasons, this should be removed, after the camel inspection and research, determined, replaced and other methods to solve.

It may be a problem set up in your workstation, it is recommended that you go to the "Chromatography World" ** to see, this ** is very professional in chromatography and will be of great help to you.

Dilute phase conveying typically uses high airflow velocities and low solid-gas ratios over distances of up to several hundred meters. The gas is often conveyed by air, and the power is generally provided by the roots blower, and the material is suspended in the pipeline. The main characteristics of the press-fed conveying method are large conveying capacity, long conveying distance, and stable operation.

The main feature of suction conveying is that it can be conveyed from low place (or bulk place), multiple points to high places, and one point. Pressure feeding and suction feeding can be combined to meet special conveying requirements.

It should be that the chain is long and needs to be tightened at the tail.

Then it depends on the drive chain of the motor, which should be tightened when it is long.
