Analysis of the control principle of the water level of stainless steel water tank
The stainless steel water tank is made of stainless steel plate, color steel plate, etc., closed-cell flame-retardant self-extinguishing polystyrene board or polyurethane as the core layer. By optimizing the combination, the inner and outer layers can achieve the best insulation effect together. The water tank has the shape. Excellent features such as high aesthetics, high mechanical strength, excellent performance and easy assembly. Applicable to schools, hospitals, factories, large hotels, hotels and restaurants with large water consumption. The following YESIN introduces the control principle of the water level of stainless steel water tank:
The buoyancy method measures the liquid level according to the principle of force balance, usually by means of a float of a hollow steel body, so that it can float to the liquid level when balanced. When the liquid level changes, the float will follow the surface movement of the liquid, so the displacement of the float can be measured to know the amount of liquid level change.
According to the shape of the float, there are float type, float type, magnetic float type, float type, etc.; according to different mechanisms, it can be divided into steel belt type and lever type.
Due to the limitation of the length of the lever arm, the lever type float level gauge is generally only used for small-range measurement or as a liquid level signal switch, such as water tank water level control. If the indicator mechanism of the lever type float level gauge is replaced by a converter, the liquid level can be converted into an electric signal for remote transmission, and the relay can be controlled to open and close by a certain method, which is called a liquid level with upper and lower limit alarm functions. Controller.
The technical advantage of the float type liquid level gauge is that the float type liquid level gauge has the characteristics of simple structure, convenient debugging, good reliability and high precision.
Gabion Mesh
Gabion mesh including : heavy gabion/hexagonal mesh, gabion box, gabion mesh sack, welded gabion mesh, Prevention rockfall Mesh.
Gabion mesh's production processes : material inspection- PVC coating- machine weaving- alignment- cutting- edge strengthening- assembly- packing- transporting
The material of gabion mesh is low carbon steel wire, and then will be hot-dipped galvanized, re-plated with Galfan or PVC, so as to improve the durability of the gabion mesh under all sorts of environments.
Applications of gabion mesh :
It has the effect of controlling water capacity, prevent soil and water from flowing,the protecting and improvement of the ecological environment. Gabion can be employed in a variety of ways to stabilize soil conditions around bridges and river bank protection.
