Hydraulic oil flow meter manufacturer, hydraulic oil meter
I. Overview of Turbine Flowmeter RTLW Turbine Flowmeter is composed of turbine flow sensor and display instrument. It is manufactured by foreign advanced technology and is one of the most ideal flowmeters for liquid metering. The flowmeter has the characteristics of simple structure, high precision, convenient installation and maintenance. This product is widely used in petroleum, chemical, metallurgy, water supply, papermaking, environmental protection, food and other fields. It is suitable for measuring stainless steel 1Cr18Ni9Ti, 2Cr13 and corundum Al2O3, hard alloy without corrosion, and no fiber, particles, etc. Impurity liquid. If it is used together with a display instrument with special functions, it can be used for automatic quantitative control and over-alarm alarm. Second, the turbine flowmeter product features: 1. The sensor is a carbide bearing thrust type, which not only ensures accuracy, but also improves wear resistance. 2. The structure is simple, firm and easy to assemble and disassemble. 3. The measuring range is wide and the lower limit flow rate is low. 4. Low pressure loss, good repeatability and high precision. 5. It has high resistance to electromagnetic interference and vibration. Third, the working principle of the turbine flowmeter: the fluid flows through the sensor housing. Since the blade of the impeller has a certain angle with the flow direction, the momentum of the fluid causes the blade to have a rotational moment, and the blade rotates after overcoming the friction torque and the fluid resistance. Stable, under certain conditions, the speed is proportional to the flow rate. Due to the magnetic permeability of the blade, it is in the magnetic field of the signal detector (composed of permanent magnet and coil). The rotating blade cuts the magnetic line and periodically changes the coil. The magnetic flux is such that an electric pulse signal is induced at both ends of the coil, and the signal is amplified and shaped by the amplifier to form a continuous rectangular pulse wave having a certain amplitude, which can be transmitted to the display instrument to display the instantaneous flow rate and the cumulative amount of the fluid. 18936754809
4.0MM SPC Vinyl Flooring can be easily installed on different type of floor base, either concrete, ceramic or existing flooring;
It`s formaldehyde free, completely safe flooring covering materials for both residential and public environment.
UV coating is a very important and necessary processing for SPC Flooring (Rigid vinyl plank), which is processed after the extrusion or lamination and before profiling (chamfering).
The main reasons for UV coating on SPC flooring (Rigid vinyl plank) are as to enhance the surface wear-resistance feature, we use 0.3mm (12mil) or 0.5mm (20mil) wear-layer on our SPC Vinyl Flooring to make it strong wear-resistance for heavy traffic or home using.
