Detailed Description
Embodiments of the present disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and intended for the purpose of explaining the present disclosure and are not to be construed as limiting the present disclosure.
A diaphragm rupture determining method, apparatus, electronic device, and storage medium of a diaphragm compressor according to an embodiment of the present disclosure are described below with reference to the accompanying drawings.
Fig. 1 is a flow chart illustrating a method for determining diaphragm rupture of a diaphragm compressor according to an embodiment of the present disclosure.
The diaphragm rupture determining method of the diaphragm compressor is configured in the diaphragm rupture determining device of the diaphragm compressor for illustration, and the diaphragm rupture determining device of the diaphragm compressor can be applied to any electronic equipment so that the electronic equipment can perform the diaphragm rupture determining function of the diaphragm compressor.
The electronic device may be a personal computer (Personal Computer, abbreviated as PC), a cloud device, a mobile device, etc., and the mobile device may be a mobile phone, a tablet computer, a personal digital assistant, a wearable device, a vehicle-mounted device, etc. with various hardware devices including an operating system, a touch screen, and/or a display screen.
As shown in fig. 1, the diaphragm rupture determining method of the diaphragm type compressor may include the steps of:
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 formed from three layers of diaphragms, and its middle diaphragm is equipped with a small groove for connecting oil pressure or air pressure with pressure switch by means of pressure-guiding tube after the oil side diaphragm or air side diaphragm is broken, when the detected pressure exceeds the set pressure threshold value, the diaphragm breakage alarm signal is triggered, and the diaphragm compressor is closed. However, after long-term operation or shutdown of the diaphragm assembly, the three layers of diaphragms may not be completely in close contact with each other, gas may be present between the diaphragms, or a slight leak may occur in the seals on both sides of the diaphragms, allowing outside air to enter between the diaphragms through the edges of the diaphragms. When the diaphragm compressor starts to operate, the gas enters the pressure guiding pipe through the middle diaphragm channel, so that false alarm is caused, and the problem of tripping of the diaphragm compressor is solved. Thus, in embodiments of the present disclosure, air within the diaphragm may be exhausted prior to operation of the diaphragm compressor.
Alternatively, after the solenoid valve connected to the diaphragm is activated to exhaust the air in the diaphragm, the solenoid valve may be closed after a preset second period of time.
The second period of time 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 air in the diaphragm, so as to prevent the diaphragm compressor from generating false alarm after being started and affecting the normal working condition of the diaphragm compressor. After the electromagnetic valve is opened for a period of time, the electromagnetic valve can be closed, so that the electromagnetic valve is prevented from being in an opened state all the time in the normal working process of the diaphragm type compressor, and the diaphragm cannot be judged correctly when the diaphragm is broken.
Alternatively, a pressure transmitter, a pressure sensor and other devices can be used to obtain the pressure value at each moment in the pressure guiding pipe. The present disclosure is not limited in this regard.
It should be noted that, during the operation of the diaphragm compressor, the pressure value in the pressure guiding tube connected to the diaphragm may be obtained in real time. The pressure value in the pressure guiding 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 guiding pipe can be increased along with repeated movement of the diaphragm in the working process of the diaphragm type compressor.
And step 103, determining the change trend of the pressure value of the diaphragm in the first time period according to the pressure values of all the moments in the pressure guiding pipe.
The first period may be a period of time before the preset current time. For example, the first period of time may be ten minutes, five minutes, etc., which is not limited by the present disclosure.
Alternatively, only the pressure values at each moment in the first time period may be stored, and the trend of the change of the pressure values in the first time period may be determined, and if the membrane 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 and the first time period is 5 minutes, only the pressure value at each time in the [ t1-5, t1] time period may be saved, and the pressure value saved before time t1-5 may be deleted.
Alternatively, if the trend of the pressure value is a rapid increase trend, the membrane is judged to be broken. If the pressure value change trend is a slow increasing trend, judging that the diaphragm is not broken.
It can be understood that if the diaphragm breaks, air in the gas compression chamber or the hydraulic oil chamber rapidly flows into the pressure guiding pipe, so that the pressure value in the pressure guiding pipe rapidly rises. Therefore, if the trend of the pressure value in the first time period is a rapid increase trend, the membrane is judged to be broken.
If the diaphragm is determined to be broken according to the change trend of the pressure value, a worker can be prompted to close the diaphragm mode compressor to replace the diaphragm.
In the embodiment of the disclosure, firstly, a solenoid valve connected with a diaphragm is started to discharge air in the diaphragm, then, in the working process of a diaphragm type compressor, pressure values at all moments in a pressure guiding pipe connected with the diaphragm are obtained, and then, according to the pressure values at all moments in the pressure guiding pipe, the pressure value change trend of the diaphragm in a first time period is determined. And finally, determining whether the diaphragm is broken or not according to the pressure value change trend. Therefore, before the diaphragm compressor works, air in the diaphragm is discharged, and then whether the diaphragm breaks 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 is improved.
Fig. 2 is a flow chart illustrating a method for determining diaphragm rupture of a diaphragm compressor according to an embodiment of the present disclosure, as shown in fig. 2, the method for determining diaphragm rupture of a diaphragm compressor may include the following steps:
in step 201, a solenoid valve associated with the diaphragm is activated to vent air from within the diaphragm.
The specific implementation manner of step 201 and step 202 may refer to the detailed descriptions in other embodiments in the disclosure, and will not be described in detail herein.
As shown in fig. 3, the solenoid valve S connected to the negative pressure ventilation duct 1 may be first activated to exhaust air in the diaphragm, and then the pressure value at any time in the pressure introduction pipe may be acquired by using the pressure transmitter P in the pressure introduction 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 a fault. The pressure transmitter P is connected with a distributed control system (Distributed Control System, DCS) which can monitor the pressure value in the pressure guiding pipe.
And 203, determining the change trend of the pressure value in the first time period before any moment when the pressure value at any moment in the pressure guiding pipe is larger than a first threshold value.
It can be understood that the first threshold value can be set, and under the condition that the pressure value at any moment is greater than the first threshold value, more air exists in the membrane, and the possibility of rupture of the membrane possibly exists, so that early warning can be sent out to prompt staff under the condition that the pressure value is greater than the first threshold value, and whether the membrane is ruptured can be judged according to the pressure value change trend in the first time period before the early warning moment is sent out.
The specific implementation manner of step 204 may refer to the detailed description of other embodiments in the disclosure, and will not be described in detail herein.
In step 205, in response to the pressure value being greater than a preset second threshold, the solenoid valve is activated to vent air within the diaphragm, wherein the second threshold is greater than the first threshold.
It can be understood that when the pressure value is greater than the first threshold, but the staff does not judge whether the diaphragm is broken in time or not, or judges that the diaphragm is not broken, because the pressure value in the pressure guiding pipe is greater than the first threshold due to the air existing in the diaphragm, the electromagnetic valve can be started to discharge the air in the diaphragm under the condition that the pressure value in the pressure guiding pipe is greater than the second threshold. The pressure value in the pressure guiding pipe is prevented from being too high under the condition that the diaphragm is not broken, so that the diaphragm type compressor stops working.
In step 206, in response to the solenoid valve being in an activated state and the pressure value being less than a third threshold, the solenoid valve is closed, wherein the third threshold is less than the first threshold.
It will be appreciated that in the event that the pressure value is greater than the second threshold value, the solenoid valve is activated, air within the diaphragm is expelled, and after a portion of air has been expelled, the solenoid valve may be closed in the event that the pressure value within the pressure line is less than the third threshold value. And continuously monitoring the pressure value in the pressure guiding pipe so as to continuously judge whether the diaphragm is broken or not.
For example, the first threshold is 0.08 megapascal (MPa), the second threshold is 0.1MPa, and the third threshold is 0.01MPa, then when the pressure value is greater than 0.08MPa, an early warning is sent to prompt a worker to judge whether the diaphragm is broken according to the trend of the pressure value in the time period before the early warning time, if the diaphragm is not broken, the electromagnetic valve is opened under the condition that the pressure value is greater than 0.1MPa, air in the diaphragm is discharged, when a part of air is discharged, the pressure value in the pressure guiding pipe is less than 0.01MPa, the electromagnetic valve is closed, and then the pressure value in the pressure guiding pipe is continuously monitored. If the membrane breaks, the machine is stopped to replace the membrane.
It should be noted that the foregoing examples are merely illustrative, and are not intended to be specific limitations of the first threshold, the second threshold, the third threshold, etc. in the embodiments of the present disclosure.
According to the embodiment of the disclosure, firstly, an electromagnetic valve connected with a diaphragm is started to discharge air in the diaphragm, then, in the working process of a diaphragm type compressor, pressure values of all moments in a pressure guiding pipe connected with the diaphragm are obtained, under the condition that the pressure value of any moment in the pressure guiding pipe is larger than a first threshold value, the pressure value change trend in a first time period before any moment is determined, whether the diaphragm breaks or not is determined according to the pressure value change trend, finally, under the condition that the pressure value is larger than a preset second threshold value, the electromagnetic valve is started to discharge 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. Therefore, before the diaphragm compressor works, air in the diaphragm is discharged first, after the diaphragm compressor works, whether the diaphragm is broken or not is judged according to the pressure value change trend, and under the condition that the diaphragm is not broken, the electromagnetic valve is opened for discharging air, so that whether the diaphragm is broken or not can be accurately judged, and under the condition that too much air exists in the diaphragm, the air in the diaphragm can be discharged, and the normal work of the diaphragm compressor is ensured.
In order to achieve the above embodiments, the present disclosure also proposes a diaphragm rupture determining apparatus of a diaphragm type compressor.

As shown in fig. 4, the diaphragm rupture determining apparatus 400 of the diaphragm type compressor may include: the exhaust module 410, the first acquisition module 420, the first determination module 430, and the second determination module 440.

In one possible implementation, the first determining module 430 is specifically configured to:
and under the condition that the pressure value at any moment in the pressure guiding pipe is larger than a first threshold value, determining the pressure value change trend in the first time period before any moment.
