Abstract
The utility model belongs to the technical field of instrument measurement, and relates to complete equipment for measuring depth of a piston of a gas holder. The device for measuring the depth of the piston of the gas holder is composed of a steel wire rope, a guide pulley, a displacement rotating shaft, a mounting bracket, a spring coupling, a photoelectric position encoder, a signal intelligent processing unit, a skidding balance weight unit and the like. The device for measuring the depth of the piston of the gas holder is characterized in that the mounting bracket, the displacement rotating shaft, the photoelectric encoder and the spring coupling are mounted in an explosion-proof instrument box in combination; one end of the explosion-proof instrument box connected with the steel wire rope is connected with a movable gas holder while the other end thereof passing through the displacement rotating shaft is connected with the skidding balance weight unit; the rise and the fall of the gas holder drives the photoelectric position encoder through the displacement rotating shaft to work, and a gas holder depth signal is converted to be 4-20 mA after being processed with operation processing by the signal intelligent processing unit and directly output. The device is simple and convenient to operate, high in sensitivity, accurate and reliable, explosion-proof, easy to maintain and suitable for a dry gas holder, and also can be used for the latest Wiggins gas holder.
Description
Technical field:
The present utility model belongs to the instrument measurement field, relates to a kind of complete equipment of measuring the gas chamber depth pistion.
Background technology:
In order to reclaim metallurgy, the coal gas resource of industries such as petrochemical industry, actively practice energy-saving and emission-reduction work, in recent years, the construction of gas chamber is in fast development, efficiently move in order to guarantee the gas holder safety and stability, height and the travelling speed data of measuring gas holder in real time are key parameters, the method that present case is measured gas holder height all is to adopt electron waves measurement instruments such as ultrasound wave or radar, because of the principle of electron waves measurement instrument all is that time domain measurement principle reflection interval by reflection wave is converted into distance, and the gas chamber outer wall is the circular steel structure, end face also is an arched top, this structure very easily causes the instrument reflected signal noise jamming to occur, and reflected signal and shakiness thereof cause the frequent saltus step of altitude information, can not measure the gas holder depth pistion by true and accurate, bring very big hidden danger for the safety in production operation.
Summary of the invention
The utility model patented product solves the deficiency of above-mentioned technology, provides a kind of new safety and stability reliable gas holder measurement mechanism.Apparatus of the present invention are made of wire rope, angle sheave, displacement rotation axis, mounting bracket, spring coupling, optoelectronic position scrambler, signal intelligent processing unit, skidding counterweight element etc.It is characterized in that mounting bracket, displacement rotation axis, photoelectric encoder and spring coupling aggregate erection are in explosion-proof instrument box, connecting wire rope one end links to each other with the gas holder piston, the other end through the displacement rotation axis links to each other with the skidding counterweight element, the lifting of piston drives the action of optoelectronic position scrambler through the displacement rotation axis, through signal intelligent processing unit calculation process, be that 4-20mA directly exports with the gas holder height signal transition.In actual use, the signal of the photoelectric encoder of gathering, after data computation processing, output can directly be connected to digital displaying meter and directly show, also exportablely access to that PLC or DCS dispatch control system height show, highly warning and travelling speed warning function, the technology interlocking of participation device operation highly is controlled the be correlated with switch of terminal valve of gas holder, raising automation degree of equipment and security and stability automatically to certain numerical value.
The utility model can be widely used in fields such as Ferrous Metallurgy, crude oil refinery, municipal air feed, can be to the gas holder height measurement of safe ready promptly and accurately, and simple installation, main equipment are all installed on the outside vestibule of gas holder, the anti-explosion safety level, maintenance is little.
