The device is additionally provided with alarm 5, and alarm 5 is connect with liquid level sensor 3, and liquid level sensor 3 incudes in collector box
When environment belongs to abnormality, solenoid valve 2 is controlled by transmission signal and opens valve exhaust, but as 2 exception of solenoid valve, Huo Zhexin
When number transmission abnormality, valve is not opened, and the still gas collection of collector box 1, collector box internal environment continues to change, when variation is more than certain
When value, liquid level sensor 2 sends a signal to alarm 5 and is alerted, to prompt staff's unit exception, need to manually be situated between
Enter.
In the specific implementation process, which is passed through to the exhaust outlet of connecting hole 101 oil resistant exhaust pipe 602 and oil pump 2
Connection, the mounting height of the device are higher than the height of oil pump 6, install in the oil machine in rear pump or output pump in collector box 1, collector box 1 is logical
It crosses fixed anchor ear 4 to be fixed in the fixable equipment around oil pump, such as on barometric cylinder, to liquid level after installing
Liquid level sensor is configured, and solenoid valve action value and warning value is arranged.
When work, the oil in oil circuit can bring portion gas into, and gas passes through the exhaust outlet 601 of oil pump 6, pass through oil resistant and be vented
Pipe 602 enters collector box 1, and collector box 1 realizes the collection to gas, and after collecting gas, pasta can decline, when liquid level sensor 3
When sensing that fuel head decrease beyond action value, liquid level sensor 3 signals to solenoid valve 2, and solenoid valve 2 is opened valve and carried out
Exhaust, after gas discharge, pasta rises in collector box 1, and when the height of rising is more than the height of action value, liquid level sensor 3 is sent out
The number of delivering letters gives solenoid valve 2, and solenoid valve closes valve and stops deflating.
When 2 exception of solenoid valve or liquid level sensor transmit the transmission process exception of signal to solenoid valve 2, liquid level is lower than
When normal level of liquid, solenoid valve 2 does not open valve deflation, and collector box 1 continues gas collection, and liquid level continues to decline in collector box 1, works as liquid level
When dropping below warning value, liquid level sensor 3 sends a signal to alarm 5 and is alerted, and reminds staff that need to manually be situated between
Enter, carries out manual exhaust.
