Drainage systems are very important at home or in public places. They can drain the water we use in time without causing water plugging. There are many kinds of drainage systems. One of the small series to be said today is siphon drainage. Let's take a look at what the siphon drainage principle is and the related knowledge.

What is the principle of siphon drainage

The principle of siphon drainage is that siphoning can also 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.

Siphon drainage construction points:

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

3、We must apply correct and even force during welding connection

4, the welding cut surface must be vertical 90 °.

The above is the principle of siphon drainage introduced by Xiaobian, as well as the construction points. After understanding the main points of construction, the construction can be done in place. If you want to choose a company for siphon drainage drainage system construction, you must choose a regular company. In order to ensure their own interests.

Mortar Lab Equipment

In order to develop the mortar formulation or Quality control for mortar production, mortar lab is necessary to be established. There are quite some basic equipments or accessories for a standard mortar lab such as mortar mixer with different volume, portable or table-type pull-off tester for tensile adhesion test, flexural & compressive test machine, universal testing machine for elongation test, drying oven or curing chamber for controlled temperature and humidity, seiving machine for sand grading and so on. Except the international standard requiremnt, some special test method can also be fulfilled by some tailor-made facilities, which is also possible to be designed or manufactured here.
