Introduction to Water Meters Composition of Water Meters
Water meter is something we usually touch, and it is closely related to our daily life. Here, SH-METER will introduce the common sense about water meters, so that everyone has a deeper understanding of water meters.
As the name implies, water meter is an instrument related to water. It is a precision instrument that records water flow (volume).
In terms of its working principle, it can be roughly divided into
(1) Power rotor water meter
(2) Piston water meter
(3) Electronic metering water meter and remote control water meter, etc. In developed countries such as Europe and the United States, the use of remote and electronic metering is mostly, while in today's society, power rotor and piston water meters are used more. With the development of social economy and the continuous emergence of new technologies, new electronic water meters will have a good development prospect. In view of the fact that most of the power water meters commonly used , sh-meter will give a rough introduction to the representative power rotor type. To
The structure and working principle of the rotor type {turbine type, double meter type, etc. are all called power meters} water meters
Rotary wing water meters can be roughly divided into:
(1) Table bolt
(2) Watch case
(3) Three parts of the watch core, of which the watch core is the most important part of the entire instrument just like the brain is to the human body.
The watch heart can be roughly divided into from top to bottom:
(1) Dial
(2) Reduction gear box
(3) Wing wheel
(4) Wing wheel box
(5) Water filter.
Dial: The dial is the display mechanism of water flow (according to the different production processes, it can be divided into digital display/pointer display and digital pointer dual display-double water meter and other styles. The dial shows the production location/model/standard working pressure of the water meter, etc. .
Reduction gear box: The reduction gear box is the reduction mechanism of the water meter. It is located below the dial and is connected to the pointer of the dial through a gear shaft. Its working principle is to slow down the transmission speed of the wing wheel through the toothing of gears of different diameters, and Finally, the rotation amount of the wing wheel is displayed on the dial.
Wing wheel: The wing wheel is composed of bearing gears, bearings, wing blades, fixed water spring lining (bakelite damping parts, center and wear-resistant core), and its function is to transmit the hydraulic force to the reduction gear box.
Wing wheel box: its components are from top to bottom atmosphere drainage hole, water inlet, (note: the drainage hole is slightly larger than the water inlet), fixed water spring, adjusting hole, and adjusting plate.
Water filter: filter out impurities in the water, protect the watch core and extend the service life of the water meter. (The blocking of the water filter mesh will increase the rotation speed of the wing wheel.)
