Product description:

Jing Chuan LC Series oval gear flow meter
I. Product Overview:
LC Series oval gear flowmeter is a volumetric flowmeter is particularly suitable for measuring the flow of high viscosity heavy oil, diesel oil, lubricating oil, polyvinyl alcohol, resins and other media, it is generally oval gear flow meter, also known as oil table can be directly read out the sum of the liquid flow through the pipeline is widely used in petroleum, chemical, pharmaceutical and other industries.
Second, the principle:
LC Series oval gear measuring portion flowmeter primarily consists of two intermeshing oval gear and housing (measuring chamber) posed, oval gear in the measured medium pressure • p = pl-p2 role, have an effect moment When rotated (a) position, since P1) P2;. in the role of P1 and P2 together torque generated by the wheel rotates clockwise A generation; the half-moon wheel volume between A and housing MEDIUM discharge to the outlet; and drive wheel B for counterclockwise rotation; in this case A is a driving wheel; B is a driven wheel; in (b) shows an intermediate position on, A and B are active round; in (c) as shown on the location; P1 and P2 acting on A wheel resultant moment is zero; the role of the co-B wheel torque to rotate counterclockwise rotation B; and to have been sucked into the volume of media row to the half-moon outlet; then B is a capstan; A is a driven wheel; and (a) shown on the case is just the opposite so cyclical, round A and B each wheel driven alternately from one another to rotate, the measured medium half. described the plot as a unit again and again to the outlet from the inlet discharge. Apparently, the figure (a), (b), (c), the only represent 1/4 weeks oval gears situation, and they have been discharged measured medium is a half-moon volume so each revolution of the oval gear parallelism of the measured medium amount of meniscus volume four times through the oval gear meter meteor volumetric flow rate Q is:
Q = 4nυ0
Where: n-- oval gear rotation frequency (rev / sec);
υ0-- half-moon part of the volume (shellfish).
Thus, under certain conditions meniscus volume υ0 oval gear flow meter, as long as the measured oval gear rotation speed n, you can know the flow of the measured medium.
Third, the product features:
l high accuracy; wide flow range; repeatability;
l helical rotor evenly; small vibration; long life;
l changes in the measured viscosity liquids insensitive, particularly suitable for measuring high viscosity liquids;
l simple structure; small size; light weight;
l easy to install, before the table without having to install straight sections;
Fourth, the technical parameters:
1. Accuracy class: 0.5, 0.2 (typically -10-60 degrees);
2. Applicable medium temperature: -20-80 degrees up to 200 degrees in the case plus the radiator;
3, nominal pressure: min 1.01.62.54.06.4 five kinds of pressure levels;
4, the measured viscosity of the liquid: 0.6 - 200 MPa s, the high viscosity of up to 200-3000 MPa.s;.
5, material: cast iron type divided, cast type and stainless steel type;
LC-A Type Cast Iron oval gear meter is widely used in various oil and measurement of non-corrosive liquid medium cast iron;
LC-E type cast steel oval gear flow meter; a high voltage; metering low corrosive media;
LC-B-type stainless steel oval gear flow meter; widely used strong corrosive liquid medium; metering salts and organic compounds; if acid; base;
6, measuring range:
Flow range m3 / h
