The air pressure change of pneumatic element is often provided with baroceptor 35 on the pipeline in list H gas circuit between connected pneumatic element all the way,
This is the gas circuit principle of pneumatic element to be measured, referring to Fig. 9.
By taking gas path control valve and list H valve as an example, single H gas circuit actual act operating condition is as follows:
Odd-side high gear turns low gear: for main tank in gear, gas path control valve mandril is in compressive state, and switching preselector valve is to low
Gear is set, and list H valve control terminal has air pressure at this time, and list H valve is pushed to complete conversion of the high gear to low gear, and speed changer realizes that low gear is pre-
Choosing.Since gas path control valve mandril compresses, i.e., gas path control valve venthole is in off state, and list H valve air inlet at this time has no gas
Pressure input.When main tank hangs neutral gear, gas path control valve mandril returns to free position, and the long ventilation of gas path control valve, compression are empty at this time
Gas switches through gas path control valve, list H valve to the low gear position of auxiliary box cylinder (i.e. execution cylinder), auxiliary transmission to low gear.Solution
The shift synchronizer of odd-side caused by basic transmission of having determined is preselected in gear beats tooth problem.
Odd-side low gear turns high gear: for main tank in gear, gas path control valve mandril is in compressive state, and switching preselector valve is supreme
Gear is set, and list H valve control terminal is without air pressure at this time, and list H valve completes conversion of the low gear to high gear under the action of control terminal spring force,
Speed changer realizes high gear pre-selection.Since gas path control valve mandril compresses, i.e., gas path control valve venthole is in off state, this
When list H valve air inlet have no air pressure input.When main tank hangs neutral gear, gas path control valve mandril returns to free position, at this time gas circuit control
The long ventilation of valve processed, compressed air is through gas path control valve, list H valve to the high gear position of auxiliary box cylinder (i.e. execution cylinder), secondary speed change
Device switches to high gear.Solve the problems, such as that basic transmission preselects caused odd-side shift synchronizer in gear and beats tooth.
Equally, by taking gas path control valve and list H valve as an example, the course of work of single H gas circuit pneumatic element fatigue life testboard
It is as follows:
Gas circuit is from low gear to high gear switching action
Cut-off: the compressed air after pressure stabilizing after 34 pressure regulation of air cleaner, into gas path control valve and preselector valve into
Port；Switching two five-way electromagnetic valves 33 makes that cylinder 20 is driven to switch to low gear by high gear, drives transverse direction by gear-shifting rocker arm 23
Shifting block on gear lever 14 is rotated, and rotational angle is limited by limit plate 17；Shifting block compression gas circuit control valve top at this time
Bar is in compressive state, and gas path control valve venthole is in off state, and single H valve is without air inlet.
Pre-selection: shifting block switching driving assembly 7 stirs preselector valve shifting block to be measured and switches to high gear by low gear, list H valve control at this time
End processed is without air pressure, and list H valve completes conversion of the low gear to high gear under the action of control terminal spring force, since single H valve is without air inlet, this
When be list H valve core shift in place realize preselect.
Shift gears in place: two five-way electromagnetic valves 33 of switching make that cylinder 20 is driven to switch to high gear by low gear, are shaken by shift
Arm 23 drives the shifting block on lateral gear lever 14 to be rotated, and rotational angle is limited by limit plate 17；Shifting block compresses at this time
Gas path control valve mandril is in free state, and compressed air leads to the high gear position of execution cylinder through gas path control valve, list H valve,
Complete gear shifting action of the low gear to high gear.
Gas circuit is from high gear to low gear switching action
Cut-off: the compressed air after pressure stabilizing after 342 pressure regulation of air cleaner, into gas path control valve and preselector valve into
Port；Switching two five-way electromagnetic valves 33 makes that cylinder 20 is driven to switch to low gear by high gear, drives transverse direction by gear-shifting rocker arm 23
Shifting block on gear lever 14 is rotated, and rotational angle is limited by limit plate 17；Shifting block compression gas circuit control valve top at this time
Bar is in compressive state, and gas path control valve venthole is in off state, and single H valve is without air inlet.
Pre-selection: shifting block switching driving assembly 7 stirs preselector valve shifting block high gear to be measured and switches to low gear, and list H valve controls at this time
There is air pressure at end, and list H valve is pushed to complete conversion of the high gear to low gear, is at this time the shift of list H valve core since single H valve is without air inlet
Pre-selection is realized in place.
Shift gears in place: two five-way electromagnetic valves 33 of switching make that cylinder 20 is driven to switch to high gear by low gear, are shaken by shift
Arm 23 drives the shifting block on lateral gear lever 14 to be rotated, and rotational angle is limited by limit plate 17；Shifting block compresses at this time
Gas path control valve mandril is in free state, and compressed air leads to the low gear position of execution cylinder through gas path control valve, list H valve,
Complete gear shifting action of the high gear to low gear.
In addition to the test of above-mentioned fatigue life, also to the through-current capacity of pneumatic element and let out using flowmeter trolley 3
Leakage quantity is tested:
1. pneumatic element through-current capacity is tested
This test belongs to the content of pneumatic element performance detection, and test schematic will need measured piece 38 (i.e. referring to Figure 11
The pneumatic element of test) it keeps opening gas source in test gas circuit on a certain state incoming stream meter trolley 3, adjusting pressure regulation
Valve 32 can measure under certain air pressure the maximum stream flow of 38 access gas circuit of measured piece at this time；Other states for switching measured piece 38 can
Test the maximum stream flow of the other access gas circuits of measured piece 38.Data of this result as examination sample flow ability.
2. pneumatic element leakage test
Measured piece 38 (pneumatic element tested) is kept a certain state before test and incited somebody to action by test schematic referring to Figure 12
Gas outlet under this state blocks, and before test gas circuit ventilation, closes the second air circuit breaker valve 36 and third air circuit breaker valve 36,
The first air circuit breaker valve 36 is opened, is supplied to 38 air inlet of measured piece, pressure regulator valve 32 is adjusted, by gas circuit air pressure adjustment to testing gas
Pressure.Second gas circuit flowmeter and third gas circuit flowmeter are respectively the flowmeter of wide range and small-range, first open the second gas circuit
Switch valve 36 closes the first air circuit breaker valve 36, and it is the quilt that the numerical value is read after numerical stability on the second gas circuit flowmeter
Survey leakage rate result of 38 test mode of part under this measuring air pressure；If the leakage numerical quantity shown at this time is too small, openable
Three air circuit breaker valves 36 close the second air circuit breaker valve 36, read the numerical value i.e. after numerical stability on third gas circuit flowmeter
For leakage rate result of 38 test modes of the measured piece under this measuring air pressure.(guarantee other portions of air circuit connection before test
The equal No leakage in position).Switching measured piece 38 other states repeat above step test the leakage rate under other states as a result, this
Test result is the important evidence for detecting pneumatic element sealing performance and whether meeting the requirements.
