Detailed Description
Reference will now be made in detail to the embodiments of the present disclosure, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and intended to be illustrative of the present disclosure, and should not be construed as limiting the present disclosure.
A diaphragm rupture determination method, apparatus, electronic device, and storage medium of a diaphragm compressor according to embodiments of the present disclosure are described below with reference to the accompanying drawings.
Fig. 1 is a schematic flow chart of a method for determining a diaphragm rupture in a diaphragm compressor according to an embodiment of the present disclosure.
The present disclosure is exemplified in that the diaphragm rupture determination method of the diaphragm compressor is configured in a diaphragm rupture determination apparatus of the diaphragm compressor, which may be applied to any electronic device so that the electronic device may perform a diaphragm rupture determination function of the diaphragm compressor.
The electronic device may be a Personal Computer (PC), a cloud device, a mobile device, and the like, and the mobile device may be a hardware device having various operating systems, touch screens, and/or display screens, such as a mobile phone, a tablet Computer, a Personal digital assistant, a wearable device, and an in-vehicle device.
As shown in fig. 1, the diaphragm rupture determination method of a diaphragm compressor may include the steps of:
It should be noted that the diaphragm in the diaphragm compressor is used to divide the diaphragm compressor into a gas compression chamber and a hydraulic oil chamber. The diaphragm group in the diaphragm compressor is composed of three layers of diaphragms, a small groove is formed in the middle diaphragm and used for connecting oil pressure or air pressure with a pressure switch through a pressure guiding pipe after the oil side diaphragm or the air side diaphragm is broken, and when the detected pressure exceeds a set pressure threshold value, a diaphragm breaking alarm signal is triggered and the diaphragm compressor is closed. However, after a membrane stack is operated for a long time or stopped, the three membranes cannot be completely tightly attached to each other, gas exists between the membrane layers, or slight leakage may occur in the seals on both sides of the membranes, so that external air enters between the membrane layers through the edges of the membranes. When the diaphragm compressor starts to operate, the gas enters the pressure leading pipe through the middle diaphragm channel, so that false alarm is caused, and the diaphragm compressor is tripped. Therefore, in the embodiment of the disclosure, before the diaphragm compressor operates, the air in the diaphragm may be discharged.
Alternatively, after the solenoid valve associated with the diaphragm is activated to vent air from the diaphragm, the solenoid valve may be closed after a preset second period of time.
Wherein, the second time period may be 5 minutes, 3 minutes, 1 minute, etc., which is not limited by the present disclosure.
It can be understood that before the diaphragm compressor works, the electromagnetic valve connected with the diaphragm can be opened first to remove the air in the diaphragm, so as to prevent the situation that after the diaphragm compressor is started, false alarm is generated to influence the normal work of the diaphragm compressor. And then, the electromagnetic valve can be closed after being opened for a period of time, so that the situation that the electromagnetic valve is always in an open state and the diaphragm cannot be correctly judged when the diaphragm is broken in the normal working process of the diaphragm compressor is prevented.
Optionally, a pressure transmitter, a pressure sensor, and other devices may be used to obtain the pressure value at each time in the pressure guiding pipe. The present disclosure is not limited thereto.
It should be noted that, during the operation of the diaphragm compressor, the pressure value in the pressure guide pipe connected to the diaphragm can be obtained in real time. The pressure value in the pressure guide pipe can reflect whether air exists in the diaphragm group, and if the air exists in the diaphragm group, the pressure value in the pressure guide pipe can be increased along with the repeated movement of the diaphragm in the working process of the diaphragm compressor.
And 103, determining the pressure value variation trend of the diaphragm in the first time period according to the pressure value at each moment in the pressure guide pipe.
The first time period may be a time period before a preset current time. For example, the first time period may be ten minutes, five minutes, etc., as the present disclosure does not limit.
Optionally, only the pressure value at each time in the first time period may be saved, and the change trend of the pressure value in the first time period may be determined, and if the diaphragm is not broken in the first time period, the pressure value before the first time period may be deleted, so that the storage space may be saved.
For example, when the current time is time t1, the first time period is 5 minutes, only the pressure value at each time in the time periods [ t1-5, t1] can be saved, and the pressure value saved before the time t1-5 is deleted.
And step 104, determining whether the diaphragm breaks or not according to the pressure value variation trend.
Optionally, if the pressure value variation trend is a rapidly increasing trend, the diaphragm is judged to be broken. If the pressure value variation trend is a slowly increasing trend, the diaphragm is judged not to be cracked.
It is understood that if the diaphragm is broken, air in the gas compression chamber or the hydraulic oil chamber may rapidly flow into the pressure guide pipe, resulting in a rapid increase in the pressure value in the pressure guide pipe. Therefore, if the pressure value variation trend in the first time period is in a rapid increase trend, the diaphragm is judged to be broken.
It should be noted that, if it is determined that the diaphragm is broken according to the pressure value variation trend, the worker may be prompted to turn off the diaphragm mode compressor to replace the diaphragm.
In the embodiment of the disclosure, the electromagnetic valve connected to the diaphragm is first started to discharge air in the diaphragm, then, in the working process of the diaphragm compressor, pressure values at various moments in the pressure guide pipe connected to the diaphragm are obtained, and then, according to the pressure values at various moments in the pressure guide pipe, a pressure value variation trend of the diaphragm in a first time period is determined. And finally, determining whether the diaphragm breaks or not according to the pressure value variation trend. Therefore, before the diaphragm type compressor works, air in the diaphragm is discharged firstly, and then whether the diaphragm breaks or not is determined according to the change trend of the pressure value, so that the influence of the air in the diaphragm on the pressure value is avoided, and the accuracy of judging whether the diaphragm breaks or not is improved.
Fig. 2 is a schematic flow chart of a method for determining a diaphragm rupture of a diaphragm compressor according to an embodiment of the present disclosure, and as shown in fig. 2, the method for determining a diaphragm rupture of a diaphragm compressor may include the following steps:
in step 201, a solenoid valve connected to a diaphragm is activated to exhaust air from the diaphragm.
The specific implementation forms of step 201 and step 202 may refer to detailed descriptions in other embodiments in the present disclosure, and are not described in detail here.
As shown in fig. 3, the electromagnetic valve S connected to the negative pressure ventilation duct 1 may be activated to exhaust air in the diaphragm, and then the pressure value at any time in the pressure guiding pipe may be acquired by using the pressure transmitter P in the pressure guiding pipe. Wherein, a manual valve 2 is connected between the pressure transmitter P and the diaphragm, and the manual valve 2 is used for closing the manual valve when detecting whether the pressure transmitter P has faults. The pressure transmitter P is connected to a Distributed Control System (DCS) that can monitor the pressure value in the pressure guide pipe.
It can be understood that a first threshold value can be set, and under the condition that the pressure value at any moment is greater than the first threshold value, the situation that more air exists in the diaphragm and the possibility of diaphragm rupture possibly exists is indicated, so that under the condition that the pressure value is greater than the first threshold value, an early warning can be given out to prompt a worker, and whether the diaphragm ruptures can be judged according to the pressure value change trend in a first time period before the early warning moment is given out.
And step 204, determining whether the diaphragm breaks or not according to the pressure value variation trend.
The specific implementation form of step 204 may refer to detailed descriptions in other embodiments in this disclosure, and details are not repeated here.
And step 205, responding to the pressure value being larger than a preset second threshold value, starting the electromagnetic valve to exhaust the air in the diaphragm, wherein the second threshold value is larger than the first threshold value.
It can be understood that, when the pressure value is greater than the first threshold value, but the worker does not judge whether the diaphragm breaks in time, or judges that the diaphragm does not break, because the pressure value in the pressure introduction pipe is greater than the first threshold value due to the air existing in the diaphragm, the electromagnetic valve may be activated to discharge the air in the diaphragm under the condition that the pressure value in the pressure introduction pipe is greater than the second threshold value. The pressure value in the pressure guide pipe is prevented from being too high under the condition that the diaphragm is not broken, so that the diaphragm type compressor stops working.
And step 206, in response to the solenoid valve being in the starting state and the pressure value being smaller than a third threshold value, closing the solenoid valve, wherein the third threshold value is smaller than the first threshold value.
It is understood that the solenoid valve is activated to discharge the air in the diaphragm in the case where the pressure value is greater than the second threshold value, and the solenoid valve may be closed in the case where the pressure value in the pilot tube is less than the third threshold value after the air is partially discharged. And continuously monitoring the pressure value in the pressure guide pipe, thereby continuously judging whether the diaphragm is broken or not.
For example, if the first threshold is 0.08 megapascals (MPa), the second threshold is 0.1MPa, and the third threshold is 0.01MPa, an early warning is issued when the pressure value is greater than 0.08MPa, so as to prompt an operator to judge whether the diaphragm is ruptured according to a change trend of the pressure value in a time period before the early warning is issued, if the diaphragm is not ruptured, the electromagnetic valve is opened to discharge air in the diaphragm when the pressure value is greater than 0.1MPa, and after a part of air is discharged, the electromagnetic valve is closed when the pressure value in the pressure introduction pipe is less than 0.01MPa, and then the pressure value in the pressure introduction pipe is continuously monitored. If the diaphragm breaks, the machine is stopped to replace the diaphragm.
It should be noted that the above examples are only simple examples, and cannot be taken as specific limitations of the first threshold, the second threshold, the third threshold, and the like in the embodiments of the present disclosure.
According to the embodiment of the disclosure, the electromagnetic valve connected with the diaphragm is started firstly to discharge air in the diaphragm, then in the working process of the diaphragm compressor, pressure values at all times in the pressure guide pipe connected with the diaphragm are obtained, under the condition that the pressure value at any time in the pressure guide pipe is larger than a first threshold value, the pressure value variation trend in a first time period before any time is determined, whether the diaphragm breaks and rings is determined according to the pressure value variation trend, and finally, under the condition that the pressure value is larger than a preset second threshold value, the electromagnetic valve is started to discharge the air in the diaphragm, and under the condition that the electromagnetic valve is in a starting state and the pressure value is smaller than a third threshold value, the electromagnetic valve is closed. From this before diaphragm compressor work, discharge the air in the diaphragm earlier, later after diaphragm compressor work, judge whether the diaphragm breaks according to pressure value trend of change, under the diaphragm condition that does not break, open the solenoid valve and exhaust to not only can accurately judge whether the diaphragm breaks, can also discharge the gas in the diaphragm under the condition that has too much gas in the diaphragm, guarantee diaphragm compressor's normal work.
In order to achieve the above embodiments, the present disclosure also proposes a diaphragm rupture determining apparatus of a diaphragm type compressor.
