Described aerating unit 3 is made of ball valve, high pressure air filling gun head, CNG holding bottle, and described ball valve is the two-position three way ball valve.
Working principle is as follows, and complete machine of the present invention comprises control unit 1, compressor unit 2 and aerating unit 3, and the present invention is connected with the natural gas in home pipeline, and behind start button 16, display lamp 17 is bright, and safety control software carries out self check to the complete machine working state.Finish for pressure, temperature, after power supply status was checked, the present invention entered holding state.Touch screen 18 is visual with the various parameters of complete machine, the operator understands complete machine working state and various parameters by touch screen 18 and selects automatic operation mode or manual operation mode is operated the present invention, after the operator selects automatic operation mode, trigger start key in the touch screen 18, anti-explosion motor 6 is started, drive compressor 5 work by belt, 0.00bar in the natural gas line is sucked in the compressor 5 to 3ar pressure rock gas.And, rock gas being transported to ball valve by high pressure hose 4 through four dehydrator filters 7, ball valve is selected to add natural gas injection in the CNG holding bottle by the air filling gun head after the aerating direction.
Should be noted that based on different pipe natural gas pressure condition differences, this paper is called the variable pressure rock gas with the pipeline pressure rock gas, this is meant that usually natural gas in home is based on certain pressure and through pre-process.
In order to reach the purpose of safety anti-explosive, compressor unit 2 should be positioned over the place that ventilates among the present invention.This is based on rock gas than the upwards volatilization of products such as gasoline, in atmosphere, dilute, and anti-explosion motor 6 places compressor unit 2 bottoms, at the case front panel and the rear board of compressor unit 2 ventilation shutter 15 is set, and rotates the back at cooling fan 8 and forms axial cooling gas flow and reach cooling effect.
Should be noted that although the invention process example has provided cabinet to satisfy suitable ventilation, this demonstration meeting is along with installation situation is adjusted
Provided for example 3bar(45 psi of natural gas line pressure although should also be noted that the invention process example), this demonstration meeting is adjusted according to pipeline pressure pressure sensor 13 or for low-pressure safety valve 10 input journeys.
After complete machine entered holding state, touch screen 18 showed main management software main menu, showed on the main menu that three module buttons are used to drive automatic mode, diagnostic mode, manual mode.
When the operator selects the automatic mode operation button.Pressure transducer 13 numerical value are read in touch screen 18 demonstrations, and the numerical value of temperature transducer 14 shows to have opened to stop button, and sets alarm button and the timer button that button sets operating range based on parameter.If the All Alerts button all is shown as working state.The operator touches start key and adds gas and stand under the automatic operation mode and work.
When the present invention works under automatic mode, safety control software is according to pressure transducer 13 numerical value, temperature transducer 14 numerical value, timer value, solenoid valve on solenoid valve on the rock gas suction tude 11, the rock gas drain pipe 12 is sent the instruction executable operations, after timer arrives the setting blowing time, open electromagnetic valve on the rock gas drain pipe 12 with gaseous emissions in the compressor 5, with the water of deposition in the dehydrator filter 7, oily regular discharge, thereby realize that the oneself of gas station in the aerating process is great clearly.The quick release of compressed natural gas under pressure state, thus can realize compressor 5 and each pipe interior oneself cooling because of heat exchanging process.
When the present invention works, reach the working value that sets when pressure under automatic mode.Safety control software is closed the solenoid valve on rock gas suction tude 11, the high pressure hose 4, opens the solenoid valve on the rock gas drain pipe 12, because the effect of one-way cock and ball valve, the pressurized gas in the high pressure hose 4 can not be back to compressor 5.Solenoid valve shuts natural gas in home body on the rock gas suction tude 11, gas is discharged through rock gas drain pipe 12 in the compressor 5.The software of safety control is simultaneously closed frequency variator, and motor quits work, and adds gas and finishes
Examination is pointed out, in the aerating working procedure, because of the complex working condition environmental change, for by safety control software various solenoid valves being made instruction with kind of a situation reply.
The present invention is directed to the excessive temperature that may occur in compressor unit 2 working procedure; overtemperature protection system is set in software; when temperature is too high; temperature transducer 14 sends current signal to PLC, sends instruction by PLC after being judged by safety control software the solenoid valve on the rock gas drain pipe 12 is moved to reduce temperature.
The present invention is directed to the rising of unknown cause temperature and may endanger compressor unit 2, overtemperature point is set in safety control software reports to the police.PLC sends instruction and cuts off converter power supply, and the solenoid valve of opening on the rock gas drain pipe 12 is also shut down to discharge pressurized gas.
When the frequency variator embedded software is found overcurrent, after the overvoltage, put in order power frequency according to electrical signal and PLC collaborative work height.
Should be pointed out that in the aerating process compressor unit 2 loads increase along with pressure increases.When frequency variator can increase electric current supply and adopt vector control mode to increase with realization pressure by embedded software, anti-explosion motor 6 moments of torsion increased synchronously.
After the operator selects manual mode.Safety control software is not executing instruction to each mechanical part.Operation for any parts is operated the corresponding button on touch screen 18 by the operator.Safety control software only moves according to operator's instruction.Because the possible misoperation of operator is equipped with high-pressure safety valve 9 and low-pressure safety valve 10 in compressor unit 2.If owing to operator's misoperation causes compressor unit 2 overpressure, after reaching safety valve to set working pressure, opens automatically pressure to guarantee compressor unit 2 not overvoltages.If for example pressure surpasses 255bar, thereby thereby Safety valve is discharged the overvoltage partial pressure by the overpressure valve plate that opens the safety-valve.
After the operator entered the diagnosis button, the operator set temperature transducer 14, pressure transducer 13 running parameters after can at first inputing password.Operative norm when PLC will set reference record and store as safe mode work.
The natural gas in home pipeline pressure adopts the low pressure standard according to different technologies and safety standard, for example adopts 2 PSI to adopt the 3kpa standard to 5 PSI pressure (about 0.13bar is to 0.3bar) China.This pressure rock gas is increased to 3600 PSI(250 Bar), do not fill perhaps that excessive temperature rises and causes security incident in compression process.
In the present invention design, adopt air-cooled level Four X type compressor, along with the running of frequency variator under different operating modes, cooling fan 8 and compressor 5 with rotation speed operation in proportion to realize cooling.
