Abstract
The invention relates to a mechanical cabinet position converter of a gas tank, which belongs to the technical field of measurement. The mechanical cabinet position converter is arranged on a corridorsteel structure of the gas tank; a signal converter arranged on a bracket in a protection cover is connected with the mechanical cabinet position converter through a flexible coupling; and the signalconverter is also connected with a digital-analog converter arranged in an explosion-proof tank through a special explosion-proof cable. The mechanical cabinet position converter of the gas tank adopts a measurement mode of the combination of a coder, the flexible coupling, the bracket, the external digital-analog converter and the explosion-proof tank to convert signals of the mechanical cabinetposition converter of the gas tank so as to convert the signals of the mechanical cabinet position converter into standard 4-20 mA DC signals and send the signals to a basic automatic control system,thereby better monitoring the safe operation of the gas tank. The novel mechanical cabinet position converter not only can be used in dry type gas tanks, but also can be used in Man-type tanks.
Description
Technical field
The invention belongs to field of measuring technique, relate to a kind of mechanical cabinet position converter of gas tank.
Background technology
In the gas chamber engineering project, in order to control the operation of gas chamber better, the formula that need design a mechanism level meter, also select simultaneously a kind of radar or laser level meter for use, two kinds of standby each other operations simultaneously again of equipment, the measuring error of these two kinds of equipment requires as far as possible little (technology requires usually less than 1m).
In the engineering design of gas chamber, the instrument specialty all will be joined a kind of equipment that is signal converter for the selected mechanical type level meter of combustion gas technology, so that the conversion of signals that mechanical level meter is measured becomes 4～20mA DC signal of standard to send the basic automatization control system, reach the purpose of monitoring gas chamber running status.In the gas chamber engineering design in the past, almost all be directly to use gas cabinet cabinet position signal converter.See accompanying drawing 1: mechanical level meter 2 is installed on the gas chamber claustra steel construction 1, and the signal converter 6 that is installed in protective cover 3 on the support 5 is connected with mechanical level meter 2 by flexible clutch 4.But use experience for many years shows, directly adopts signal converter that following drawback is arranged:
1) at first cost an arm and a leg, every about 12～150,000 yuans, and price is going up year by year;
2) because the mechanical type level meter of technological design is non-standard equipment, cabinet for every kind of gas chamber holds, its shaft coupling all is not the integer circle in the number of turns of normal travel and the rotation of accident stroke, therefore, the output of the standard signal of corresponding gauge signal converter 4～20mA DC will be revised during field adjustable repeatedly, require mechanical type level meter manufacturer to cooperate at the scene simultaneously and revise its shaft coupling, just can satisfy production engineering specifications substantially, but precision is not high, often measuring error is bigger;
3) scene is debugged repeatedly and technology shaft coupling equipment is revised repeatedly, and the manpower waste is big, inefficiency.
Summary of the invention
The present invention designs a kind of mechanical cabinet position converter of gas tank exactly, is used for substituting the conventional in the past gas chamber machinery cabinet position signal converter that uses.The present invention's machinery level meter is installed on the gas chamber claustra steel construction; signal converter rack-mount in protective cover is connected with mechanical level meter by flexible clutch, and signal converter is connected with digital to analog converter in being installed in explosion-proof tank by explosion-proof private cable.
Adopt this Typical Gas Tank mechanical cabinet position converter that following tangible benefit is arranged:
1) the Typical Gas Tank mechanical cabinet position converter uses the scrambler+flexible clutch+support+this multiple measurement mode of digital to analog converter and explosion-proof tank of joining than directly using cabinet position signal converter that better applicability is arranged outward; And price is cheaper.Do not need to consider again whether shaft coupling rotates the integer circle, and applicability is better, and bigger price advantage is arranged, save about 100,000 yuans of investments for every.
2) can improve the measuring accuracy of gas chamber mechanical type level meter, reduce the measuring error between mechanical type level meter and radar or the laser level meter, can control the operation of gas chamber better;
3) need not to consider whether shaft coupling rotates the integer circle in normal travel and accident stroke in the design, can when design, solve Signal Matching and mechanical connection problem once.Raise labour productivity significantly, reduce the time that the engineering debug personnel debug at the scene.
The present invention is that 4～20mA DC that the measuring-signal with mechanical level meter converts standard to send the basic automatization control system, reaches the running status of complete monitoring gas chamber piston, and whether the monitoring gas chamber purpose of safe operation.Thereby better the running status of gas chamber piston is monitored, and then the safe operation of gas chamber is monitored.
The present invention can obviously save investment, saves human and material resources, can also improve measuring accuracy.
Description of drawings
Fig. 1 is an existing gas chamber machinery cabinet position signal converter;
Fig. 2 is a mechanical cabinet position converter of gas tank of the present invention.
Among the figure, part 1 is a gas chamber claustra steel construction; Part 2 is mechanical level meter; Part 3 is a protective cover; Part 4 is a flexible clutch; Part 5 is a support; Part 6 is a signal converter; Part 7 is an explosion-proof tank; Part 8 is a digital to analog converter; Part 9 is explosion-proof private cable.
Embodiment
Be described further below in conjunction with 2 pairs of specific embodiments of the invention of accompanying drawing:
The present invention adopts scrambler+flexible clutch+support+join digital to analog converter and this multiple measurement mode of explosion-proof tank that gas chamber machinery level meter signal is changed outward, become 4～20mA DC of standard to send the basic automatization control system mechanical level meter conversion of signals, thereby monitor the safe operation of gas chamber better.This novel mechanical cabinet position converter both can use in dry gas holder, also can be used in graceful formula cabinet.
