The traditional instrument internal structure principle in detail

Abstract: the principle of traditional instrument internal structure details information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. The internal structure of the traditional water meter can be divided into the shell from the outgoing, sleeve, 3 big inner core. Shell is made of cast iron, after water out of the water inlet through the bottom of the casing annulus, here called the annulus. In the annular space with ring on the room. More flow meter manufacturers choose model price quote you are welcome to inquire, here is a traditional instrument internal structure principle in detail the article details. The internal structure of the traditional water meter can be divided into the shell from the outgoing, sleeve, 3 big inner core. The shell is made of cast iron, water out of the water inlet through the bottom of the shell after annulus, here called & other; The ring chamber & throughout; 。 In the annular space above & other; On the ring chamber & throughout; And the outlet is same. A filter with a small hole on the bottom of the sleeve, the filter impurities from the water. Sleeve side has two rows of round hole, hole position coincided with the casing annulus on the up and down, obviously, discharge is into the hole, the top is the drainage holes. Of particular note is that the two rows of holes are along the tangent of the circular sideways. Pay attention to the up and down two rows of holes in the opposite direction. Water flows from bottom hole along the tangent direction, certainly will form a rotating flow, this is very important for water meter work. Inner core is divided into the upper, middle and lower three layers, seen from the window is upper, only the pointer and dial. Actually zui key is lower, there is a plastic wheel, wheel side has a lot of plastic blade, called & other; Impeller & throughout; 。 Impeller's position at the right moment in casing hole formed by the lower rotating flow, water wheel blade, produce torque, rotating impeller. Leading drive too, the greater the flow, the more urgent, the faster the impeller turns. Impeller axis vertical to the middle, the above there is a small gear, and with it & other; Decimal number gear & throughout; Meshing, achieve the goal of cumulative number of revolutions. “ Decimal number gear & throughout; Gear is used whenever a single-digit turn ten laps, ten digits gear turns a circle. In other words, a single gear on a business trip, ten digits gear turns one over ten circle. Single gear is active, turns the ten digits by it. In fact each level decimal finish, with two pairs of gears so that the rotation direction is consistent, which is a pair of transmission ratio, 9:30 at 10:30, the other pair is in series with the both of the total transmission ratio is the product of the two, namely zero. 099999, can approximate to zero. 1. According to this calculation, if you want to read seven digits ( Before the decimal point is read four black dial, read three decimal places are red scale) , with 12 on gear. Plus some other purpose, in the middle and small space to squeeze into 18 axis and 34 gear, also is a high density installation. This kind of water meter because of its simple and cheap, can be in damp environment use for a long time without the need for maintenance, and need not power, power also does not affect the work will still be the advantages of long service. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
