Description
Technical Field
The utility model relates to the field of diaphragm compressors, in particular to a pressure sensor detection device of a diaphragm type hydrogen compressor.
Background
The pressure sensor for detecting the diaphragm pressure in the existing diaphragm type hydrogen compressor only detects when leaving the factory, and ensures that the pressure sensor is normal when leaving the factory. However, whether the hydrogen is damaged during the transportation process or not after the diaphragm type hydrogen compressor is connected, cannot be confirmed. Because the pressure sensor detects the pressure of the inner cavity of the diaphragm group structure of the diaphragm type hydrogen compressor, and the pressure of the inner cavity of the diaphragm group structure is unchanged under normal conditions, the pressure value collected by the pressure sensor is basically unchanged, the pressure of the inner cavity of the diaphragm group structure can be changed only after the diaphragm on the air side or the oil side is broken, and when the generated pressure reaches the set alarm value of the pressure sensor, the PLC system connected with the pressure sensor can alarm and stop. However, since the pressure sensor is not detected again after being connected to the diaphragm type hydrogen compressor, whether the pressure sensor is damaged or abnormal due to installation cannot be confirmed, and since the pressure sensor is not detected after the diaphragm type hydrogen compressor is used for a while, whether the pressure sensor is damaged or abnormal due to other factors cannot be confirmed as well. And under the condition that the pressure sensor is damaged or abnormal, if the air side or oil side membrane of the diaphragm type hydrogen compressor is broken, the pressure sensor can not give an alarm, and the diaphragm type hydrogen compressor can not stop, so that hydraulic oil can be driven into a pipeline of the hydrogen compressor, and the hydraulic oil enters a gas cylinder of a hydrogenation vehicle through a hydrogenation machine to influence the performance of an engine of the hydrogenation vehicle.
Disclosure of Invention
The utility model provides a pressure sensor detection device of a diaphragm type hydrogen compressor, which can detect the condition of a diaphragm pressure sensor of the diaphragm type hydrogen compressor at any time and confirm whether the state of the pressure sensor is normal or not.
The utility model provides a pressure sensor detection device of diaphragm type hydrogen compressor, includes diaphragm type hydrogen compressor, pressure sensor, diaphragm type hydrogen compressor's diaphragm group structure inner chamber's release passageway is connected with three way connection, three way connection's one end is connected the bleeder valve, and four way connection is connected to the other end, other three ports of four way connection are connected respectively pressure sensor, manometer and be used for detecting pressure sensor's gas inlet valve, gas inlet valve's left interface connection detects gaseous trachea.
Preferably, the pressure sensor is connected to a PLC system, and the alarm value is set to be 100 kilopascals.
Preferably, the gas inlet valve is a manual valve or an automatic valve.
The utility model has the beneficial effects that:
the utility model ensures the reliability of the pressure sensor, can detect the condition of the pressure sensor at any time, and can help staff to detect the pressure sensor when the pressure sensor fails or is abnormal. The problem that when the diaphragm of the diaphragm type hydrogen compressor is broken, the pressure sensor is damaged or abnormal and is not stopped in an alarm way, so that hydraulic oil finally enters the gas cylinder of the hydrogenation vehicle is avoided, and the performance of the vehicle is affected.
