Description

LATER OBJECT LIQUID COUNT.

The invention relates to the field of mechanical engineering, in particular flow measurement} bumps and gases.

Known 1sarlvrny counter A.S. USSR JM6044I, containing cor- V / pus with a nozzle.sh, upper and lower housing covers, a drum with blades and a counting mechanism.

Known blade sensor volumetric flow rate of the liquid, and.with. USSR No. 12033 (58, containing a stator, a rotor with grooves axially aligned with it, x in which spring-loaded blades are installed, and a working chamber of constant section located between the stator and the rotor and a spring loaded cracker into which two old plates are inserted.

There is a known vane volumetric liquid meter of Danie.pb company, containing 11: a housing, a rotor located in it, in the slots of which there are five radially mounted plates And a guide ring. The closest to the invention by its technical essence and the achieved result is a liquid meter with - a knob, a.ss.SSSR b 1359678, consisting of a housing, a chamber with a rotor, in the grooves of which the plates radially move,

The disadvantage of all of the flow meters listed above is the complicated etching system of the radially moving plates.

. The aim of the present invention is to simplify the design of the flow meter, increasing the reliability and accuracy of measuring fluid flow.

This goal is achieved by the fact that the cylinder is coaxially mounted with the rotor and the housing has displaced centers of the external and internal surfaces, in which transverse slots of the liquid inlet and outlet are made on the opposite sides, three radial slots are made in the rotor, along which three through plates, on the end surfaces of which thin strips / scrapers / of spring steel are fixed at an angle.

The presented drawings show a sectional plan, “rig,” a general sectional view, fiIt, 2, insert section, riel, 3, and plate configurations, FSH. ,4,

there is an opening for mounting the rotor shaft, and the lower part of the housing, FIG. 2, closes the bottom with the landing Agstom for the rotor shaft,

The cylindrical insert 2, Fig. 1, fI2..3, represents a cylinder with centers of the outer and inner surfaces displaced, and slots for entry and exit are made on the opposite walls of equal thickness;

The rotor 3, Fig. I, represents a cylinder with a shaft in the upper part. Three slots are made in the lower part of the rotor for mounting and radially moving the plates. A cover is attached to the lower part of the rotor to extend the plates.

The plates have the configurations as shown in Fig. 4, Strips / scrapers / made of spring steel are mounted at the end of the plates at an angle. The purpose of the scrapers is to prevent accumulation of deposits on the walls and to center the plate in the radial direction.

The flowmeter works as follows. Due to the difference in pressure, the rotor starts to rotate, while the plates move along the slots, cutting off the volume of liquid in the chamber space. For one revolution of the rotor, a strictly defined volume of liquid is displaced. The measurement of flow and quantity is reduced to measuring the rotor speed with subsequent conversion to the volume.

A prototype was developed and manufactured. Bench tests are underway.
