Specific embodiment
1, the realization of pressure chamber piston pressure metering system.
1) pressure chamber for designing proper volume, shape, pressure rating enables to accommodate piston, piston specific weight, weight
Automatic (or remote control) handler of code and the driving device of piston rotation；Pressure chamber should also have observation window or observation device, with
Observe pistons work state.
2) piston manometer is passed through into pressure bay floor by piston cylinder and seals fixation.
3) necessary pressure chamber pressure guiding pipe, piston pressure pressure guiding pipe, pressure chamber injection pressure equipment, high pressure is configured to adjust and set
It is standby, form complete pressure chamber piston manometer metering system.Power cabin piston manometer metering system should be equipped with inclination when necessary
Degree adjustment and measuring device, guarantee that the piston of pressure gauge is in vertical working condition.
2, the pressure chamber piston manometer course of work.
1) by tested differential pressure meter, high-low pressure interface is separately connected piston pressure pressure guiding pipe and pressure chamber pressure guiding pipe.
2) by pressure chamber injection pressure equipment, reach stable suitable static pressure to pressure chamber injection compressed gas (or liquid).
3) equipment is adjusted by high pressure, generates suitable pressure in piston manometer bottom, while starting piston rotation
Driving, makes piston be in normal operating conditions.
4) differential pressure relative to pressure chamber pressure is generated between pressure chamber pressure guiding pipe and piston manometer pressure guiding pipe at this time
Value, the value need to make the amendment such as counterweight buoyancy, temperature when necessary.The pressure that pressure chamber pressure guiding pipe and piston manometer pressure guiding pipe are drawn
Power applies two different pressures to connected differential pressure meter, for detecting the differential pressure indicating value of differential pressure meter.
Claims (1)
1. pressure chamber piston manometer, pressure bay floor is passed through including pressure chamber and by the piston cylinder of piston manometer, and in
