The air compressor intermittent operation device can monitor, display, store and set data such as lubricating oil pressure, lubricating oil temperature, ambient temperature, air compressor rotating speed, air compressor cylinder surface temperature, air cylinder pressure and the like.
The operation of the air compressor is controlled by combining the actual gas utilization condition of the tank special vehicle, by adding a clutch mechanism (including but not limited to electromagnetic, hydraulic, mechanical clutch and the like) between the power source and the air compressor, monitoring the operation data (including but not limited to system pressure, operation time, temperature and the like) of the system through a control system and automatically or manually giving a signal to the clutch mechanism through the control system so as to control the operation state (including whether to operate or not, or the speed of operation and the like) of the air compressor.
In order to check the reliability of the intermittent operation system, the system is matched with a laboratory measurement and control system: the working environment of the air compressor can be simulated, and various parameters of the system are monitored.
The working environment of the simulated air compressor requires monitoring and controlling the temperature of the lubricating oil, the pressure of the lubricating oil and the ambient temperature, and the rotation speed of an input shaft of the air compressor.
The heating element is arranged in the lubricating oil tank to heat the lubricating oil, and meanwhile, the air compressor is also a heat dissipation device, and the oil temperature regulator is further arranged at the oil inlet of the lubricating oil connecting pipeline and used for automatically regulating the temperature of the lubricating oil, so that the purpose of controlling the lubricating oil temperature is achieved.

The temperature in the temperature box is basically kept in a certain temperature range by the heater arranged in the temperature box where the air compressor is arranged and the temperature regulating device, and when the temperature in the temperature box is higher than a set value, the temperature regulating device starts to work.
The rotating speed of the air compressor can be arbitrarily regulated and kept at a stable value by driving the belt pulley through the variable frequency motor.
In order to realize various parameters of the detection system, the clutch mechanism can obtain working signals, and the temperature of the air path and the temperature of lubricating oil are required to be detected and converted.

When the pressure sensor senses that the pressure of the compressed air in the vehicle reaches a preset value, the pressure sensor transmits a signal to the hydraulic control valve, so that the hydraulic control valve controls oil supply to enable the hydraulic clutch device to be separated, the air compressor stops running, and when the pressure of the compressed air in the vehicle is lower than the preset value, the hydraulic control valve controls oil supply to be released to enable the hydraulic clutch device to be combined, and the air compressor continues running.
When the temperature sensor senses that the heating value of the air compressor is overlarge, the hydraulic control valve controls oil supply to enable the hydraulic clutch device to be separated, and the air compressor stops running.
When the time calculator calculates that the air compressor runs for a long time, the hydraulic control valve controls oil supply to enable the hydraulic clutch device to be separated, and the air compressor stops running.
When other sensors (such as a displacement sensor and a pressure sensor) sense manual control signals, the hydraulic control valve controls oil supply or oil drainage to control the separation and combination of the hydraulic clutch device.
Operation principle of the hydraulic clutch device: the hydraulic oil flows into the oil inlet pipe 4 through the hydraulic control valve 3, then flows into the clutch shaft 5 through the oil inlet hole 17, then flows into the sleeve hole 12, and then flows into the clutch cover 6, so that reverse thrust is generated on the clutch cover 6, the clutch spring 15 is caused to compress, the inner clutch plate 13 is separated from the outer clutch plate 18, and therefore, the power output shaft 11 is separated from the clutch shaft 5, and the power output shaft 11 stops rotating.
The bearing between the clutch shaft and the shell 8 and the joint of the clutch shaft and the power input shaft 1 can be lubricated in the process that hydraulic oil enters the oil inlet hole 17 from the oil inlet pipe 4; the hydraulic oil can lubricate the power output shaft 11 when entering the sleeve hole 12; when the hydraulic oil enters the clutch cover 6, the cooling effect can be carried out on the inner clutch plate and the outer clutch plate.
When the hydraulic control valve 3 controls the hydraulic oil to be released, the clutch spring 15 expands, causing the inner clutch plate 13 to be coupled with the outer clutch plate 18, and thus the power output shaft 11 is coupled with the clutch shaft 5, and the power output shaft 11 starts to rotate.
The hydraulic control valve 3 can adopt a three-way valve, one oil inlet hole, two oil outlet holes, the oil inlet hole is connected with an oil supply system, one oil outlet hole is connected with the oil inlet pipe 4, and the other oil outlet hole is connected with the oil drain pipe.
