Abstract
The invention discloses a float-type swage discharge flow transmitter, comprising a float-type liquid level transmission device and a signal transmitting portion. In the transmission device, a cable wire embedded with steel balls rounds a turnplate, both ends of the cable wire are respectively connected with a float and a pullback weight, the central shaft of the turnplate is connected with an advance lever of a multi-turn potentiometer, an operational amplifier and a 4-20mA converter of the signal transmitting portion as well as a regulation resistance are all encapsulated in a plastic housing. The device for detecting swage discharge in the invention has simple structure, accurate transmission, good anti-pollution performance, less failure, strong ability for remote signal transmission, reliable detection, long performance life, and has important functions for discharge reduction, pollution prevention and environment protection.
Description
Technical field
The present invention relates to a kind of fluid flow pick-up unit, specifically is float type sewerage discharging flow transmitter.
Background technology
Sewage discharge point is abominable, seriously polluted and apart from central control room place far away at environment often, detect pick-up units such as sewerage discharging flow float-type commonly used, ultrasonic type at present, its measuring technique is comparative maturity, but owing to the reason of environment and the imperfection of pick-up unit, used sensor and pertinent instruments are contaminated easily, damage easily, the remote transmission effect of signal is not good enough, thus the reliability that influence detects and the serviceable life of pick-up unit.
Summary of the invention
The technical issues that need to address of the present invention are to overcome weak point of the prior art, provide a kind of energy anti-pollution, transmit signal at a distance, detecting reliability is good, the float type sewerage discharging flow transmitter of long service life.
Technical scheme of the present invention is: float type sewerage discharging flow transmitter comprises float-type liquid level gearing and signal transmitting part, improvements are that described float-type liquid level gearing is mainly by float, wire rope, rotating disk, counterweight, multiturn potentiometer constitutes, wire rope is walked around rotating disk, float and the counterweight ined succession respectively and hang in the wire rope two ends, the central shaft of rotating disk is connected with the multiturn potentiometer adjuster bar, described signal transmitting part mainly is made of above-mentioned multiturn potentiometer operational amplifier and 4～20mA converter, operational amplifier and 4～20mA converter are encapsulated in the can.
Stud with steel ball on the described wire rope, the rotating disk cylindrical is provided with and the steel ball corresponding grooves; Described can is the anticorrosion plastic housing, and outer casing inner wall scribbles screen layer.
Transmitter of the present invention send device as the important transmission and the change of entire sewage flow quantity detecting system, and it is simple in structure, and transmission is accurate, fault is few, used electronic component and electronic circuit are sealed in the good plastic casing of antiseptic property, and can shield anti-interferencely, are not subjected to the influence of sewage emission point environment.During use, float is lifting with the lifting of the water surface, drive the multiturn potentiometer rotation by wire rope, rotating disk, liquid level during according to the initial liquid level of the tested discharge of sewage and maximum flow regulates potentiometer, just the variation of liquid level can be become the variation of potentiometer resistance, the variation of resistance is amplified through the operational amplifier conversion, form the corresponding relation of potential value and liquid level, electric potential signal becomes 4～20mA current signal through 4～20mA converter again and is delivered to central control room, the remote transmission ability is strong, good reliability, final, application system is converted into flow with the variation of liquid level.This transmitter is because pollution-proof performance is good, and fault is few, so long service life.
Description of drawings
Accompanying drawing is float-type liquid level transmission structures synoptic diagram among the present invention.
Embodiment
Referring to accompanying drawing, in the float-type liquid level gearing, wire rope 6 is walked around the half-turn of rotating disk 4, its two ends link to each other with float 7 with the counterweight 1 that hangs respectively, stud with steel ball 5 on the wire rope equidistantly, the periphery of rotating disk 4 has and the steel ball corresponding grooves, transmission accurately and reliably, the adjuster bar of multiturn potentiometer 2 is connected with the central shaft of rotating disk 3.Multiturn potentiometer in this device and the operational amplifier among the present invention, 4～20mA converter all are encapsulated in inwall to be had in the enclosure-type plastic casing of screen layer.
Claims (3)
