The phenomenon of siphoning is caused by the inter-molecular gravitational force and positional difference. That is, using the difference in the pressure of the water column, the water rises and then flows to a lower level. Because the water surface of the nozzle is subject to different atmospheric pressure, the water will flow from the high pressure side to the low pressure side until the atmospheric pressures on both sides are equal, and the water level in the container becomes equal height, and the water will stop flowing. Using siphoning, the water in the container can be quickly extracted. Then we will take a look at the principle of siphon drainage and the key points of siphon drainage construction .
Siphon Drainage Introduction
The siphon was an ancient invention of mankind. As early as the 1st century BC, a strange siphon was created.
For example, in a water tank with water, put one end of the tube in water, and the other end hangs naturally in the cylinder, use the mouth to inhale at this end for a while, then loosen the mouth, then the Water will flow from the tube. Because the tube is curved, like a rainbow, it can also play a role in absorbing water. It is called siphoning.
The principle of siphon drainage
In fact, siphoning is not entirely caused by atmospheric pressure, and siphoning can occur in vacuum. The force that raises the liquid is the cohesion of the molecules between the liquids. In the event of a siphoning phenomenon, since the liquid flowing out of the pipe is more than the liquid flowing into the pipe, the gravity on both sides is not balanced, so the liquid will continue to flow in one direction. As the liquid flows into the pipe, the pressure becomes lower as it goes upward. If the liquid rising pipe is high, the pressure will decrease to generate bubbles (consisting of air or other components) in the pipe. The height of the siphon is determined by the generation of air bubbles. Because the bubbles break the liquid, the force between the gas molecules at the two ends of the bubble is reduced to zero, thereby breaking the siphon effect, so the tube must be filled with water. At normal atmospheric pressure, the siphon works better than it does under vacuum because the atmospheric pressure on the two nozzles increases the pressure inside the entire siphon. Application example: Insert one end of the water-filled hose into the water, and the other end out of the water container. The water outlet should be below the water surface. In this way, water will flow out of the container along the hose.
Absorbent stone sold in the flower market is this principle. There are many small and narrow eyes in the stone. Because of the siphon phenomenon, the water at the bottom of the stone can be sucked up for the small plants on the stone, such as green moss, and the wheat seedlings can survive. Including some siphon teapots, siphon toilets, are all principles.
Siphon drainage construction points
For the siphon drainage system, there are three main points in the construction process: construction preparation, pipeline installation and welding.
Point one: Preparation before construction
1. Adequate staffing and operation staff, set up a special project department construction management.
2. The workers with excellent quality and experience in installing siphonic rainwater drainage systems shall participate in the work of the project department and receive corresponding training before taking up the job.
3, seriously study drawings, closely cooperate with designers and construction personnel, and consider the construction plan thoroughly.
4. Set up temporary facilities and arrange reasonable stacking of materials and machinery.
5. Arrange the equipment, equipment, and auxiliary materials into the field.
6. To supervise the construction personnel in strengthening project quality, safe and civilized construction, etc.
7, stent welding and other process operators must hold certificates.
8. Strictly conduct on-site measurement according to the requirements on the drawings of the construction country, and conduct re-inspection before the installation of the pipeline to ensure that the installation of the pipeline is in full compliance with the requirements of the construction drawings and the acceptance criteria.
The second point: pipeline connection and installation
The siphon drainage discharge system must be strictly installed on the drawings when installing the pipeline to be installed. When connecting the siphon drainage drainage system, two connection methods, butt welded joints and welded pipe hoop joints, are generally used.
Point 3: Construction of Butt Welding Connections
1. We must keep the welding position and the cleanliness of the welding tool plate when welding.
2, according to the weather conditions during construction, to grasp the right welding plate welding temperature
3ã€We must apply correct and even force during welding connection
4, the welding cut surface must be vertical 90 °.
Therefore, for the siphon drainage system, it is only after understanding the main points of construction that it can be put into place. Finally, Pauli Pipeline needs to remind everyone that if everyone wants to choose a company for the construction of a siphon drainage system, it must choose a regular company so that it can guarantee their own interests.
Conclusion: The relevant information on the principle of siphon drainage and the key points of siphon drainage construction was introduced here. I hope this article will be helpful to everyone. If you still have something you don't understand, you can leave a message to Xiaobian at the bottom. We will answer your questions as soon as possible.
