Abstract
The utility model discloses a kind of monitoring alarm device of cracked diaphragm of diaphragm pump, comprise petrol station, hydraulic oil chamber, repairing passage, flow transmitter, PLC controller and alarm, one end of repairing passage communicates with petrol station, the other end communicates with hydraulic oil chamber, described flow transmitter is arranged on repairing passage, for detection of repairing flow, repairing flux signal is sent to PLC controller, the unlatching of PLC controller control alarm; The utility model arranges flow transmitter on repairing passage, repairing flow is carried out monitoring in real time and detected, if detect that repairing flow-rate ratio is larger, by PLC controller control alarm equipment alarm, realized diaphragm pump monitors and reports to the police the membrane ruptures of diaphragm pump in the situation that having oil compensation pressure, not only can be used for the monitoring of single membrane ruptures, can also be used for the monitoring that two barrier films break simultaneously.
Description
Technical field
The utility model relates to a kind of diaphragm pump, is specifically related to a kind of monitoring alarm device of cracked diaphragm of diaphragm pump.
Background technique
Diaphragm pump is a kind of important pump type, is usually used in the conveying of ore pulp material.In diaphragm pump, fluid end is divided into hydraulic oil chamber and fed sheet of a media district by barrier film, the indoor hydraulic oil that fills of hydraulic fluid chamber, to-and-fro motion by piston is sent to fed sheet of a media district by power by barrier film, because barrier film separates hydraulic oil and fed sheet of a media, avoid the mixing of the two, ensured that in piston/cylinder, moving element is worked in clean fluid, thereby extended the life-span of piston easily damaged parts.
But, in diaphragm pump running, due to fed sheet of a media, temperature and diaphragm deflection, usually make barrier film aging, make barrier film in not predictable time internal rupture, operator are difficult to find in time and process, after membrane ruptures, if frequent repairing, hydraulic oil can enter in fed sheet of a media district, increase the consumption of hydraulic oil, cause the waste of hydraulic oil; If frequent oil extraction, fed sheet of a media enters in fluid chamber, contaminated liquid compressed-oil system, the wearing and tearing that increase the parts such as piston, the working life of reducing pump.
In order to monitor breaking of barrier film, mainly contain at present pressure-sensitive alarm monitoring and change two kinds of quick alarm monitorings.Pressure-sensitive alarm monitoring is applicable to two membrane configurations, its variation that adopts pressure ring to detect force value between double-deck barrier film judges whether barrier film breaks, this structure is comparatively complicated, if ore pulp side medium barrier film has broken easy retaining pressure passage, so that can not and alarm, and cannot monitor the situation that single membrane configuration breaks.The principle of changing quick alarm monitoring is: after membrane ruptures, medium enters in hydraulic oil, makes the hydraulic oil conduction in fluid chamber, by detecting potential difference, reaches the object whether monitoring barrier film breaks.Change quick alarm monitoring simple in structure, and can monitor the situation that single membrane configuration and double-deck barrier film break simultaneously, but, change quick alarm monitoring and will realize membrane ruptures monitoring, must there are following two conditions: 1, fed sheet of a media and hydraulic oil differ larger on perveance, otherwise can not realize potential difference; 2, fed sheet of a media must enter fluid chamber, still, has in the situation of oil compensation pressure for the recharging oil device of diaphragm pump fluid chamber, even membrane ruptures, medium can not enter fluid chamber timely yet.
Summary of the invention
For above-mentioned deficiency of the prior art, of the present utility modelly provide a kind of in the situation that diaphragm pump has oil compensation pressure, the device that the membrane ruptures of diaphragm pump is monitored, reported to the police.
To achieve these goals, the technical solution adopted in the utility model is as follows:
A kind of monitoring alarm device of cracked diaphragm of diaphragm pump, comprise petrol station, hydraulic oil chamber, repairing passage, flow transmitter, PLC controller and alarm, one end of repairing passage communicates with petrol station, the other end communicates with hydraulic oil chamber, described flow transmitter is arranged on repairing passage, for detection of repairing flow, repairing flux signal is sent to PLC controller, the unlatching of PLC controller control alarm.
With respect to prior art, the utlity model has following beneficial effect:
The utility model arranges flow transmitter on repairing passage, repairing flow is carried out monitoring in real time and detected, if detect that repairing flow-rate ratio is larger, by PLC controller control alarm equipment alarm, realized diaphragm pump monitors and reports to the police the membrane ruptures of diaphragm pump in the situation that having oil compensation pressure, not only can be used for the monitoring of single membrane ruptures, can also be used for the monitoring after two barrier films break simultaneously.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Referring to Fig. 1: a kind of monitoring alarm device of cracked diaphragm of diaphragm pump, comprises petrol station, hydraulic oil chamber, repairing passage, flow transmitter, PLC controller and alarm.In petrol station, be loaded with hydraulic oil, on repairing passage, be provided with Fill valve.When diaphragm pump operation, if the few oil of hydraulic oil chamber, Fill valve is opened, and in the situation that having oil compensation pressure, the hydraulic oil in petrol station enters hydraulic oil chamber by repairing passage.Flow transmitter is arranged on repairing passage, for detecting in real time the repairing flow of repairing passage.Flow transmitter is connected with PLC controller, and PLC controller is connected with alarm.Repairing flux signal is sent to PLC controller by flow transmitter, and PLC controller receives repairing flux signal, in the time detecting that repairing flow is large, and the unlatching of PLC controller control alarm.Alarm can adopt acousto-optic instrument, also can adopt buzzer siren.
Working principle of the present utility model is as follows: because the barrier film of diaphragm pump separates fed sheet of a media district and hydraulic oil chamber, in the time of membrane ruptures, hydraulic oil in hydraulic oil chamber will enter fed sheet of a media district, now in order to ensure the normal operation of diaphragm pump, oil-supplementing system by a large amount of to hydraulic oil chamber repairing, now the repairing flow in repairing passage will become large, the flow transmitter being arranged on repairing passage detects repairing flow in real time, in the time detecting that repairing flow becomes large, by PLC controller control alarm equipment alarm, not only can be used for monitoring the situation of single membrane ruptures, the situation that can also simultaneously break for detection of two barrier films.
Finally it should be noted that, above embodiment is only in order to the technical solution of the utility model to be described but not restriction technologies scheme, although claimant has been described in detail the present invention with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, those are modified or are equal to replacement technological scheme of the present invention, and do not depart from aim and the scope of the technical program, all should be encompassed in the middle of claim scope of the present invention.
