The utility model discloses having reduced the pressure switch number of starts, having made compressed air keep the convenient pressure, reduced the cold machine load of doing, improved the output air quality, it is above to make compressor admission valve life double, improves the stability and the nature controlled of whole system greatly, has solved dry not thorough problem simultaneously.
Description
Technical field
The utility model belongs to the aerodynamic force technical field of rock gas mother station, particularly a kind of aerodynamic system of CNG mother station.
Background technique
The aerodynamic system of current CNG (CompressedNaturalGas) mother station as shown in Figure 1, comprise air compressor, air compressor is connected with gas holder, gas holder is connected with T level air filter, T level air filter is connected with cooling driers, cooling driers is external output squeezing air after connecting C level air filter, in use often there are some defects in such system layout: 1, the start and stop pressure range of air compressor pressure switch is too wide, pressure spacing is 0.3MPa, when the highest shutdown pressure of setting is 1MPa, its lower limit is 0.7MPa, now 0.7MPa can not meet the startup requirement of natural gas compressor, the startup of natural gas compressor requires it is minimum 0.8MPa, during 0.7mpa, the unloading valve of natural gas compressor can be not closed completely not because of dynamics, cause the unlatching of air valve switch too frequent with closed simultaneously, increase wearing and tearing, make service life reduction, simultaneously, exhaust gas pulses strengthens, motor load is unstable, also infringement is had to the main frame of compressor, if when the highest shutdown pressure is brought up to 1.1MPa, the cylinder superpressure of pneumatic actuator, use dangerous.2, the pressure switch of air compressor has steam to discharge because of bottom lever, pollutes contact and causes virtual connection.As replacing can cause contactor sparking to damage not in time.Can cause phase shortage after contacts of contactor damages, can not to start and contacts of contactor adhesion can not depart from, cause burn-down of electric motor, in addition, long-time high load running also can cause the speed of cylinder and piston ring to be worn and torn.3, drying is not thorough, gas holder continuous output squeezing air when gas consumption increases, compressor start when pressure drops to certain value, the pressurized air waiting time in tank entering tank body is shorter, do not have enough time to separate out condensed water to output through gas holder with regard to direct, it is particularly evident that rainy season, there was dampness in the air, adds cooling driers load, moisture in the pressurized air after causing cooling driers to export.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, and proposes a kind of aerodynamic system of CNG mother station.
The utility model solves its technical problem and takes following technological scheme to realize:
A kind of aerodynamic system of CNG mother station, comprise air compressor, air compressor is connected with gas holder by pipeline, gas holder is connected with C level air filter after 1.3MPa safety valve by pipeline, C level air filter controls to be connected with steam trap after gauge outfit through controllable silicon digital display by pipeline, steam trap is connected with cooling driers by pipeline, and pressurized air is sent after connecting T level air filter, voltage stabilizer and oil sprayer successively by pipeline by cooling driers.
And, the pipeline between controllable silicon digital display control gauge outfit and steam trap is provided with 0.95MPa safety valve further.
And the voltage stabilizing value of described voltage stabilizer is at 0.85MPa.
And the turbine oil that oil sprayer uses is No. 20 turbine oils.
Advantage of the present utility model and good effect are:
1, the utility model increases air voltage stabilizer, make output squeezing air pressure constant on 0.85MPa, the pressure switch of pneumatics has adjusted to 0.85-1.2MPa, and pressure range adds 0.5 kilogram, reduce pressure activated switch number of times, make pressurized air keep convenient pressure.
2, the utility model increases cyclone separator, effectively can not only isolate portion of water, increase pressurized air capacity simultaneously, extend pressurized air waiting time in tank, reduce cooling driers load, improve delivery air quality.
3, the utility model has changed the former mechanical pressure switches of air compressor is controllable silicon digital display meter telecontrol, improves the reliability of system.
4, the utility model adds safety valve on pressurized air output pipe, guarantees the Security of system.
5, the utility model increases oil sprayer in the pipeline of aerating island, will deliver in the part needing lubrication after No. 20 turbine oil atomizations, to extend the life-span adding gas column and sled car pneumatic element.
6, the utility model can make compressor suction valve double above working life, greatly improves the stability of total system and handling, solves dry halfway problem simultaneously.
