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 rotated in when (a) the location, since P1) P2, P1 and P2 in the role of co-generated torque to the wheel A produce clockwise round the half-moon volume between A and housing MEDIUM discharge to the outlet, and drive wheel B for counterclockwise rotation, then A is a capstan, B is driven wheels, in (b) shows an intermediate position on, A and B are active round; in (c) the position shown, P1 and P2 acting on A round co zero torque acting on the combined torque to the wheel B B counter clockwise rotation, and the half-moon sucked medium volume within the row to exit, then B is the driving wheel, 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 to 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, good repeatability;
l helical rotor rotates uniformly, vibration, and 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, high-pressure measurement, low corrosive media used;
LC-B-type stainless steel oval gear flow meter is widely used in a metering strong corrosive liquid medium, such as acids, bases, salts and organic compounds such as;
6, measuring range:
