Abstract
The invention discloses a differential liquid level monitor. According to the technical scheme, the differential liquid level monitor is characterized in that a main wheel is fixed on an encoder shaft of an encoder, the encoder is fixed on an upper board with two wire holes through an encoder carrier, an auxiliary wheel is fixed on a lower board with an oil hole through an auxiliary wheel bearing, an auxiliary shaft and two lower supports, an upper cover with an upper fixed post is hermetically fixed on a gravitational buoy with a lower fixed post, a thin steel wire is wound on the main wheel and the auxiliary wheel through the two wire holes before two ends of the steel wire are fixed to the upper fixed post and the lower fixed post respectively, a main unit case, the upper board, a guard tube with an air outlet, the lower board and a communicating pipe are fixed together through upper bolts and lower bolts after a cable, a power cord and a signal remote transmission line are connected, and the other end of the communicating pipe is fixedly communicated with a liquid tank. The technical scheme is widely applicable inevitably.
Description
Technical field:
The present invention is mainly used in the on-line continuous monitoring to liquid level.
Background technology:
Current device for continuous on-line monitoring liquid level is a lot, and main what use is two kinds of the convertible and minute-pressure throw-in types of magnetic.The convertible easy jam of level monitoring device, the resolution of magnetic is low; The anti-space of the level monitoring device of minute-pressure throw-in type electromagnetic interference (EMI) is poor, temperature drift is big, and the wrong report that often causes liquid level to transfinite brings the hidden danger of safe operation to relevant device.
Summary of the invention:
The present invention is intended to fundamentally solve the technological deficiency of prior art and patented technology existence aspect the monitoring liquid level, a kind of new technical scheme is proposed, it is characterized in that, after seizing wire is walked around main wheel and accessory whorl respectively by the cable-through hole on two upper plates, the two ends of seizing wire are separately fixed under the gravity floating drum on the fixed leg and last fixed leg, and make seizing wire that certain force of strain be arranged, by the accessory whorl bearing, countershaft, two lower carriages and undercarriage bolt are fixed on accessory whorl on the lower plate that has oil-through hole, main wheel is fixed on the scrambler axle by the key bar, and scrambler is fixed on the upper plate by scrambler frame and rack screw; Monitoring cable and junction block link together scrambler and display controller on connect with the mains line and the signal is far passed line again on display controller; Use bolt host box and upper plate and the casing upper flange that has a vent port are fixed together, with bolt down the communicating pipe flange of casing lower flange and lower plate and communicating pipe is fixed together, the other end of communicating pipe is communicated with fluid box.
The technique effect that technical scheme provided by the invention realizes is such: when the liquid level generation ascending, descending in the fluid box changes, according to the characteristic of liquid, also change synchronously by the liquid level in the communicating pipe casing, namely rise or descend.Before liquid level did not change, the gravity floating drum in the casing was actionless, and at this moment, gravity and the buoyancy of gravity floating drum reach balance.When liquid level rises, the buoyancy of gravity floating drum increases, balance is broken, the gravity floating drum just rises, thereby just drive main wheel and rotate counterclockwise by being fixed on the tensioning seizing wire on the fixed leg and following fixed leg and main wheel produce on the gravity floating drum two ends friction force, main wheel drives the scrambler rotation again, thereby scrambler is exported positive pulse signal, give display controller by the monitoring cable, by display controller signal is handled the back and carry out the monitor signal teletransmission by the signal is far passed line.When liquid level descends, the buoyancy of gravity floating drum reduces, the gravity floating drum descends under the effect of gravity, thereby driving seizing wire driving main wheel clockwise rotates, main wheel drive scrambler clockwise rotates and sends undersuing, undersuing is passed to display controller by the monitoring cable, by the signal is far passed line monitor signal is spread out of after the display controller computing again.
Technical scheme involved in the present invention compared with prior art has outstanding progress and significant technique effect, and disclosed technical scheme compact conformation is succinct, and industry is reproduced convenient, good reliability, resolution is high, has novelty, creativeness and practicality will extensively be employed.
