Description

Whether there is or not Magnetic testis close to the gas roots flowmeter of switch for a kind of band
Technical field
The utility model relates to gas roots flowmeter, whether there is or not the gases of the close switch of Magnetic testi for specifically a kind of band Rotz flowmeter.
Background technique
Gas roots flowmeter is a kind of volumetric flow metering instrument of precise measurement gas flow, high with precision, Good reliability, the features such as light-weight, the service life is long, running noises are low are suitable for measurement natural gas, town gas, propane, nitrogen, work The noncorrosive gases such as industry inert gas, the combustion gas business for being widely used in the industries such as food and drink, hotel are settled accounts, transmission and distribution network combustion gas Metering, gas pressure regulating station metering, the gas meterings such as industry and civil boiler.
The working principle of gas roots flowmeter is as follows: when gas passes through flowmeter, generating in inlet end and outlet side Pressure difference acts on the double waist wheels being linked together with high-accuracy synchromesh gear, so that double waist wheel rotations are driven, it is double during this period Confined space is formed between waist wheel and flowmeter shell inner wall and gland, periodically inflates and is vented, the revolution of double waist wheels Directly proportional to by the gas volume amount of flowmeter, the rotation of double waist wheels passes to mechanical counter through magnetic coupler, thus tired Meter flows through the volume of measurement chamber to realize the purpose of metering.
Mechanical gas roots flowmeter in process of production, needs to carry out the detection of the error of indication, and detection formula needs are adopted Collect flowmeter pulse, since the pulse frequency of mechanical gas roots flowmeter is lower, especially small flow when, test when Between can be very long, a flowmeter having needs 3 aptitude tests in more hours to complete, and production efficiency substantially reduces.
Summary of the invention
The utility model in order to overcome the deficiencies of the prior art, designs a kind of gas waist wheel of band whether there is or not Magnetic testi close to switch Flowmeter goes to detect the revolving speed for getting rid of oil sheet, to greatly shorten error-detecting using no Magnetic testi inductance approach switch Time improves production efficiency.
To achieve the above object, a kind of gas roots flowmeter of band whether there is or not Magnetic testi close to switch, including shell are designed, Inductance approach switch, it is characterized in that: the inside of the shell is embedded with rotor assembly, before the front and rear sides of shell are respectively equipped with End cap and rear end cap are equipped with synchromesh gear, the center of the synchromesh gear in the shell between rear end cap and rotor assembly Place is equipped with and gets rid of oil sheet, and inductance approach switch, the inductance approach switch are embedded on the rear end cap got rid of on rear side of oil sheet For detecting the revolving speed for getting rid of oil sheet;Machine core gear assembly, machine core tooth are equipped in shell between rear end cap and rotor assembly The front side of wheel assembly passes through drive end bearing bracket and connects magnetic coupling component, and the magnetic coupling component is equipped with counter assembly.
The front and rear sides of the rotor assembly are respectively equipped with front side board and back side panel, and the front side board and back side panel are located at shell Internal portion.
The synchromesh gear is located in the shell between rear end cap and back side panel.
The machine core gear assembly is located in the shell between drive end bearing bracket and front side board.
Compared with the existing technology, structure is simple for the utility model, and transformation is convenient, gets rid of oil using on flowmeter original structure Piece, increasing by one can detecte the revolving speed for getting rid of oil sheet without Magnetic testi inductance approach switch, as flowmeter error-detecting High-frequency impulse, the pulse signal that output detection needs, can greatly shorten the time of error-detecting, improve production efficiency.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Referring to Fig. 1, wherein 1 is inductance approach switch, and 2 be rear end cap, and 3 be to get rid of oil sheet, and 4 be synchromesh gear, after 5 are Side plate, 6 be shell, and 7 be rotor assembly, and 8 be front side board, and 9 be machine core gear assembly, and 10 be drive end bearing bracket, and 11 be magnetic coupling component, 12 be counter assembly.
Specific embodiment
The utility model is described further below according to attached drawing.
As shown in Figure 1, the inside of the shell 6 is embedded with rotor assembly 7, the front and rear sides of shell 6 are respectively equipped with front end Lid 10 and rear end cap 2 are equipped with synchromesh gear 4, the synchromesh gear 4 in the shell 6 between rear end cap 2 and rotor assembly 7 Center at be equipped with and get rid of oil sheet 3, be embedded with inductance approach switch 1, the inductance on the rear end cap 2 for getting rid of 3 rear side of oil sheet Formula is close to switch 1 for detecting the revolving speed for getting rid of oil sheet 3;Machine core is equipped in shell 6 between rear end cap 2 and rotor assembly 7 Gear assembly 9, the front side of machine core gear assembly 9 pass through drive end bearing bracket 10 and connect magnetic coupling component 11, the magnetic coupling component 11 It is equipped with counter assembly 12.
The front and rear sides of the rotor assembly 7 are respectively equipped with front side board 8 and back side panel 5, the front side board 8 and back side panel 5 It is located inside shell 6.
The synchromesh gear 4 is located in the shell 6 between rear end cap 2 and back side panel 5.
