specific Embodiment 1
[0024] Specific embodiment 1, see figure 1 and image 3 , the present invention provides a mobile compressor oil-saving method based on flow monitoring, the method includes the following steps:
[0025] S1: Set the trigger value of micro-pressure differential switch 1 to 10m3 / min;
[0026] S2: Use the first pressure regulating valve 4 to set the maximum working pressure of the compressor 9 to 21 bar when the drilling rig is working, and use the second pressure regulating valve 3 to set the working pressure of the compressor 9 to 8 when the drilling rig is changing rods or moving. bar;
[0027] S3: When the drilling rig is drilling, the micro-pressure differential switch 1 measures the air flow in the intake pipe 8 as 24 m3 / min, the micro-pressure differential switch 1 does not trigger the electric signal, the solenoid valve 2 is closed, and the compressor 9 is at 22 Work under the pressure of bar;
[0028] S4: When the drilling rig changes rods or travels and shifts, the m...
specific Embodiment 2
[0030] Specific embodiment 2, see Figure 1-3 , this technical solution provides a mobile compressor oil-saving system based on flow monitoring, including an intake pipe 8, a compressor 9, a micro-pressure switch 1, a solenoid valve 2, a first pressure regulating valve 4, a second pressure regulating valve Valve 3, shuttle valve 5, intake control valve 6, intake pipe 8, intake control valve 6, compressor 9, shuttle valve 5 are connected in sequence, micro-pressure differential switch 1 is connected to intake pipe 8, and the second pressure regulating valve 3 is connected to the solenoid valve 2, the shuttle valve 5 is connected to the first pressure regulating valve 4 and the second pressure regulating valve 3 respectively, the micro pressure difference switch 1 is connected to the shuttle valve 5 and the solenoid valve 2 respectively, and the intake control valve 6 is connected to The first pressure regulating valve 4 and the solenoid valve 2.
[0031] The micro-pressure dif...
specific Embodiment 3
[0034] Specific embodiment 3, see Figure 1-3 , the difference from the specific embodiment 1-2 is that the micro-pressure differential switch 1 controls the action of the solenoid valve 2 through the intermediate relay 10 . When the micro-pressure differential switch 1 is closed, the intermediate relay 10 is energized, the solenoid valve 2 is turned on, and the control gas passes through the second pressure regulating valve 3 . In the present invention, 16% of oil is saved.

Description
technical field [0001] The invention relates to a mobile compressor oil-saving system based on flow monitoring. Background technique [0002] Diesel engine-driven mobile screw compressors are divided into two types, one is a mobile screw compressor that provides compressed air for semi-pneumatic rock drilling rigs and down-the-hole drilling rigs, and the other is a mobile screw compressor for fully pneumatic rock drilling rigs. Mobile screw compressors that provide compressed air for down-the-hole drilling rigs. For mobile screw compressors that provide compressed air for fully pneumatic rock drilling rigs and down-the-hole drilling rigs, the compressed air provided is used to drive the drilling rig to achieve drilling, slag discharge, rotation and displacement. A large application of diesel engine-driven mobile screw compressors is mining and drilling and blasting industries that require earthwork excavation. The compressed air provided by the compressor drives a full-air ...
