Summary


DTO oval gear flowmeter is a kind of direct-reading accumulating liquid flowmeter. DTO oval gear flowmeter adds transmitter mechanism on the basic of DTO flowmeter. It can be equipped flux and instant flux. It possesses many virtues such as large testing range, high precision etc..

It is widely used in flux measurement in industrial field such as oil development, oil refining, chemical,
commerce, oil storage.


Operation Principle


  Measurement is made in the testing room. There is a pair of oval gear in it. The pair of oval gear will keep rotating on the axis under the role of liquid pressure difference between inlet and outlet. Liquid flux through the flowmeter will be known by testing gears’ rotation number
As it is showed in picture 1(a), the inlet and outlet are separated by a pair of oval gear A and B.
There is crescent-shaped space between Gear A and inner wall of the testing room (It is showed asshadow in the picture).There is a rotating torque while the total torque on Gear B is zero. Gear B will be rotated by driven of Gear A. The picture 1(b) shows the middle position of the two gears.
When the gears turn to the position showed in the picture 1(c), Gear A will lose rotating torque while Gear B will gain rotating torque. Gear A will be rotated by driven of Gear B. It is showed in the picture1(d).

 

 

 

Structure


The Model DTO oval gear flowmeter mainly consists of testing room, sealing mechanism and
counting mechanism.


1. Testing room: outcover(1) of instrument (see picture 2,3;same as pictures later)is made by cast iron. Inner space and the board (4)consists of the testing room. There are 2 stainless steel axes
(2) and a pair of oval gear(3) is sleeved on the axes.. The liquid from the inlet will be sent to the outlet through the crescent-shaped space by the gears’turn which is driven by pressure difference between inlet and outlet in flowmeter. Four times volume of crescent-shaped space will be accumulated while the gear makes one revolution round. The space between oval gear and inner wall of the testing room is very small with tens of micro-mete only to decrease leak of theinstrument.
 
2. Sealing mechanism: The testing room is sealed. The permanent magnetic sealing.Mechanism is adopted on the small caliber flowmeter(See picture 2).The partition (8)separates the active and passive permanent magnet (6) (7). Sensitivity Of the structure is high and seal is solid. Polytetrafluoroethylene plastic is used as packing seal for the big caliber fowmeter
(See picture 3). T he sealing lining (6) willl be extended to seal by change of spring (7) compression through adjusting the nut(8). The structure is rather simple and conbenient for
adjustment.


3. Counting mechanism: It includes driving wheel speed ratio adjusting mechanism and recokoning mechanism. The total rotation number and speed of a pair of gears will be passed to
the needle and wording wheel of recokoning mechanism(11).after speed changed caused by driving wheel. The total liquid volume and instant flux through the pipe will be known. Speed
ratio adjusting mechanism is used for adjusting and correcting errors of instrument.
Oval gear flowmeter is installed electrical impulses signal transmitter in the counting mechanism of the DTO oval gear flowmeter.I.E. one permanent magnet disk is fixed on the
transducer is installed on the counter. The transducer possesses merits such as long life, strong capacity of anti interference, wide working frequency, no spark, fearless of oil, grease and dust, small measurement, convenient installation. The solid testing signals can be got without contact when the magnet accesses to the induction surface with the action distances.
