Abstract
The invention discloses a probe type liquid-level meter water-wave-resistant device. A probe type liquid-level meter is installed on the upper portion of a pool, probes of the probe type liquid-level meter are immersed in liquid in the pool, the probe type liquid-level meter is in signal connection with a water supply pump and is fixed to a fixing bracket, the fixing bracket is installed on the wall surface of the upper portion of the pool, the exterior of the probe type liquid-level meter is sleeved with a rigid protective sleeve, the lower end of the protective sleeve is open, the interior of the protective sleeve is hollow, the upper end of the protective sleeve is fixed to the fixing bracket, the lower end of the protective sleeve extends below the liquid level and is lower than the lower ends of the probes of the probe type liquid-level meter, a distance exists the lower end of the protective sleeve and the inner bottom face of the pool, and the protective sleeve is communicated with the liquid in the pool only through an opening in the lower end. By means of the probe type liquid-level meter water-wave-resistant device, water waves are isolated from the probes under the circumstance that the liquid level around the probes is not influenced, the probes are not influenced by the water waves and thereby can maintain normal signals, frequent starting and stopping of the pump caused by the water waves are avoided, and the service life of the pump is effectively prolonged.
Description
Technical field
The invention belongs to field of printed circuit board fabrication, be specifically related to the modified node method of the probe-type liquid-level meter in the central pond in a kind of PCB factory.
Background technology
At present, supply water by pumping in the central pond of PCB factory inner storing water amount hundreds of ton, in order to maintain the constant of liquid level in central pond, water level height is that the probe-type liquid-level meter by being installed on certain height position on central pond controls, and the liquid level signal monitored is passed to pumping by probe-type liquid-level meter, thus control the start and stop of pumping, pond high liquid level, then pumping stops, the low liquid level in pond, then signal is to pumping, and pumping starts supplies water.But rocking because the water surface in pond often has ripples, particularly when running into vibrations or wind, when can cause the probe of liquid level gauge, having signal to pumping, ripples rock, twinkling signal disappears again, can make pumping frequent starting and stopping like this, causes pumping greatly to decline serviceable life.
Summary of the invention
In order to solve the problem, the invention provides a kind of probe-type liquid-level meter water resistant wave apparatus, this probe-type liquid-level meter water resistant wave apparatus when not affecting liquid level around probe by ripples and probe isolated, probe can not be subject to ripples impact thus keep normal signal, avoid the frequent start-stop that pumping causes due to ripples, effectively extend the serviceable life of pumping.
The present invention in order to the technical scheme solving its technical matters and adopt is:
A kind of probe-type liquid-level meter water resistant wave apparatus, probe-type liquid-level meter is installed on the top in pond and its probe to immerse in pond in liquid, described probe-type liquid-level meter is connected with water supply pump signal, be provided with a fixed mount, described probe-type liquid-level meter is fixed on described fixed mount, described fixed mount is installed on the top wall in pond, the outer cover of described probe-type liquid-level meter has the protective sleeve of a hard, the lower end of described protective sleeve is opening and inside is hollow, described protective sleeve upper end is fixed on described fixed mount and lower end is inserted into below liquid level, the lower end of described protective sleeve is lower than the lower end of the probe of described probe-type liquid-level meter, there is distance in the lower end of described protective sleeve and the inner bottom surface in described pond, described protective sleeve communicates with liquid in pond by means of only the opening of lower end.
The present invention in order to the further technical scheme solving its technical matters and adopt is:
Say further, the lower end of described protective sleeve is apart from 3 to 50 centimetres, the lower end of the probe of described probe-type liquid-level meter.Furthermore, the lower end of described protective sleeve is apart from 10 to 30 centimetres, the lower end of the probe of described probe-type liquid-level meter.
Say further, described protective sleeve is pvc pipe.
Say further, the top of described protective sleeve and the position being positioned at the top of liquid level has ventilation mouth.Furthermore, described ventilation mouth distance liquid level 20 centimetres to 1.5 meters.Preferably, described ventilation mouth distance liquid level 20-80 centimetre.
Say further, described pond is the central pond in PCB factory.
The invention has the beneficial effects as follows: probe-type liquid-level meter water resistant wave apparatus of the present invention is the protective sleeve of a sheathed hard in the periphery of probe-type liquid-level meter mainly; by protective sleeve by isolated for the ripples of probe-type liquid-level meter and surrounding; and the liquid level true altitude do not affected around probe; probe can not be subject to ripples impact thus keep normal signal; avoid the frequent start-stop that pumping causes due to ripples, effectively extend the serviceable life of pumping.
