Description
Technical field
The invention belongs to manometer standard test collimation technique field, be specifically related to one and can quickly produce 40MPa gas pressure
Power, for the automatic gas pressurization device of manometer assay calibration.
Background technology
In the verification process of manometer, some manometer is the instrument prohibiting oil (water), such as: oxygen gauge, acetylene
Other instrument such as table, this is accomplished by the compressed air with certain pressure as medium to examine and determine instrument.The pressure of traditional approach
Contracting air source mainly has a two ways: hand air pump and gas cylinder.Hand air pump is mainly used in the inspection of small-range manometer
Determine in device.Although pressure is the lowest but in order to complete normal calibration operation, operator need constantly to operate hand air pump and guarantee
Verification process has enough compressed airs, and this is a heavy muscle power job, has had a strong impact on the efficiency of calibration operation.Use
Gas cylinder provides compressed air, gas cylinder finite capacity for assay device, and maximum pressure, the most also with regard to 25MPa, is difficult to
Carrying, and along with use, storage pressure is more and more lower, and the range of overburden pressure table calibrating is more and more lower, slightly higher range
Just cannot examine and determine, so bring to calibration operation many constant, more cannot meet the need of industry spot automatic Verification manometer
Want.In order to solve this problem, people's imagination electric air pump or electric booster etc. replace gas cylinder, but existing electronic
Supercharging air equipment typically all utilizes extra power system to provide energy needed for compressed gas, and such as each gas-booster, this type of increases
Press is mostly to convert compressor, and its feature is that power is big, and output pressure and flow are big, but it is bulky, no
Can effectively utilize low-pressure gas source gas energy, capacity usage ratio is low, and the most common gas-booster lacks controller, frequently
Start-stop, very big to the electrical network of factory, the impact of gas circuit and the damage to equipment itself, it is unfavorable for pushing away in pressure calibration field
Extensively.Also there is research by reducing charger boost side piston area, reach the purpose of supercharging, but this kind of supercharger is all with compressed gas
Body is power, and supercharger driving side low-pressure gas directly discharges air, and energy loss is big, and the efficiency of system is low.Therefore can not expire
Foot industry low discharge, the needs of high pressure, everything seriously govern gas pressure instrument automatic calibrator to automatization,
Miniaturization, the direction of energy-efficientization are developed.

Device (61) is all connected with the second relay (62) with the 3rd relay (63), the second relay (62) with
Solenoid directional control valve (12) is connected, when pressurizer starts, and 24V power supply (60) output 24V unidirectional current
To the first proximity switch (9) and the second proximity switch (10)；When the first proximity switch (9) senses one-level supercharging
Connect during piston (20), the first relay (61) coil electricity, the signal of telecommunication be transferred to the second relay (62),
Solenoid directional control valve (12) one end electric magnet obtains electric, and solenoid directional control valve (12) commutates；When one-level charged piston (20)
When leaving the first proximity switch (9) induction zone, the first relay (61) coil blackout；When charged piston enters
When entering the second proximity switch (10) induction zone, the 3rd relay (63) obtains electric, and the signal of telecommunication is transferred to second
Relay (62), solenoid directional control valve (12) other end obtain electric after commutate；Connect when charged piston leaves second
During nearly switch (10) induction zone, the 3rd relay (63) dead electricity, pressurizer recovers to starting state, subsequently
Rerun.
8. a boosting method, uses the pressurizer described in claim 1, it is characterised in that: described dynamic
Power piston (18) moves right under power P effect, the power piston (18) that connects as one, piston rod
(19) moving to the right with one-level charged piston (20), now one-level pressurized cylinder (21) is low by suck simultaneously
The low-pressure gas that pressurized air source assembly (2) provides is compressed entering two-stage supercharging cylinder by the first check valve (14)
(15), meanwhile two-stage supercharging cylinder (15) sucks the sub-high pressure gas that one-level pressurized cylinder (21) is discharged, and two-stage increases
Cylinder pressure volume is different, and the volume of one-level pressurized cylinder (21) is six times of two-stage supercharging cylinder (15) volume, so one
The gas pressure intensity entering two-stage supercharging cylinder (15) after level pressurized cylinder (21) compression can increase to nearly 6 times, works as power
When piston (18) is moved to the left under power P effect, power piston (18), piston rod (19) and one-level
Charged piston (20) moves simultaneously to the left, and gas is unidirectional by second through two-stage supercharging cylinder (15) compression
Valve (13) enters air accumulator (7).
