In order to realize the said method of this mode of execution, can use the air-pressure controlling system of rig air compressor as shown in Figure 5 and Figure 6.
With reference to Fig. 5, it is the connection diagram of the corresponding system of the 3rd mode of execution of the air-pressure controlling method of rig air compressor of the present invention.This system comprises the air-pressure controlling system 5 being arranged between gas holder 2 and air compressor 1, the input end of air-pressure controlling system 5 is connected with the output port of gas holder 2, and the output terminal of air-pressure controlling system 5 is connected with the control port of the suction valve 3 of air compressor 1.
With reference to Fig. 6, it is the structural representation of the corresponding system of the 3rd mode of execution of the air-pressure controlling method of rig air compressor of the present invention.Air-pressure controlling system 5 comprises the first pressure regulation branch road 10 parallel with one another, the second pressure regulation branch road 20, the 3rd pressure regulation branch road 30, the 4th pressure regulation branch road 40 and off-load branch road 50, wherein the first pressure regulation branch road 10 comprises and is connected to the input end of this branch road and the first pressure regulator valve 21 between output terminal, the second pressure regulation branch road 20 comprises input end and the second solenoid valve 12 between output terminal and the second pressure regulator valve 22 that is connected on this branch road, the 3rd pressure regulation branch road 30 comprises input end and the 3rd solenoid valve 13 between output terminal and the 3rd pressure regulator valve 23 that is connected on this branch road, the 4th pressure regulation branch road 40 comprises input end and the 4th solenoid valve 14 between output terminal and the 4th pressure regulator valve 24 that is connected on this branch road, off-load branch road 50 comprises and is connected to the input end of this branch road and the 5th solenoid valve 15 between output terminal.
Air-pressure controlling system 5 is the control access of air compressor 1, and its output terminal is connected to reach the object of the air pressure of controlling output with the control port of suction valve 3.Suction valve 3 is pneumatic on-off valve, by its opening and closing of air-pressure controlling of its control port.Thereby the second solenoid valve 12～five solenoid valve 15 is controlled the state of the air pressure of rig air compressor for controlling the break-make of place branch road, the first pressure regulator valve 21～four pressure regulator valve 24 is for controlling the air pressure of place branch road output.When solenoid valve is switched on, solenoid valve is opened, and place branch road is connected; When solenoid valve power-off, closed electromagnetic valve, place branch road disconnects.When place branch road is connected, if the air pressure in branch road reaches the setting pressure of pressure regulator valve in this branch road, pressure regulator valve is opened, and makes air pressure can enter the control port of suction valve 3.
Below in conjunction with example explanation air-pressure controlling system 5, how the air pressure of air compressor 1 output is controlled.When air compressor 1 starts, the control port of suction valve 3 does not have air pressure, and suction valve 3 is opened, and air enters the head of air compressor 1 continuously through suction valve 3, through the air of overcompression, by main line 4, enters gas holder 2.Along with the air compressor growth of 1 operating time, the air pressure in gas holder 2 constantly increases, and the air in the gas holder 2 after supercharging enters air-pressure controlling system 5 through output port.When compressed-air actuated pressure reaches the setting value of the pressure regulator valve in the branch road of a certain connection, pressurized air enters the control port of suction valve 3 by this branch road, and suction valve 3 cuts out immediately.Now do not have outside air to enter air compressor 1, meet the pressurized air of setting pressure from 6 outputs of pressurized air output port simultaneously.After having pressurized air output, the air pressure that the air pressure in pipeline is set lower than solenoid valve, closed electromagnetic valve.Now do not have air pressure to enter the control port of suction valve 3, suction valve 3 is opened, and outside air continues to enter air compressor 1.Repeat above process, the air pressure that can realize air compressor 1 output meets the air pressure of setting.
The energising of solenoid valve and power-off can be according to operating mode need to, by controlling manually, also can automatically control by PLC or other automatic systems air pressure.Each pressure regulator valve is all independent adjustable, and user can, according to the actual conditions in building site, set the air pressure value of the pressure regulator valve of each branch road.
The first pressure regulation branch road 10 is configured to connect during operating mode in boring when rig, at rig, disconnects during in other operating modes, makes the air pressure of this rig air compressor in the first working pressure state; The second pressure regulation branch road 20 is configured to connect when changing bar operating mode when rig, at rig, disconnects during in other operating modes, makes the air pressure of this rig air compressor in the second working pressure state; The 3rd pressure regulation branch road 30 is configured to connect during in perforate operating mode when rig, at rig, disconnects during in other operating modes, makes the air pressure of this rig air compressor in the 3rd working pressure state; The 4th pressure regulation branch road 40 is configured to connect during in Awaiting Overhaul operating mode when rig, at rig, disconnects during in other operating modes, makes the air pressure of this rig air compressor in the 4th working pressure state; Off-load branch road 50 is configured to connect during operating mode in standby or walking when rig, at rig, disconnects during in other operating modes, makes the air pressure of this rig air compressor in unloading condition.
Especially, the first pressure regulation branch road 10 only comprises for controlling the pressure regulator valve 21 of air compressor delivery air pressure, and does not comprise for controlling the solenoid valve of branch road break-make.When the second solenoid valve 12～five solenoid valve 15 equal power-off, when other branch roads all disconnect, air-pressure controlling system 5 enters the first pressure regulation branch road 10 automatically, output the first working pressure.Such benefit is not only to reduce by a solenoid valve; and ensured the safety of system; such as in the situation that the equal power-off of all solenoid valves causing due to misoperation or the system failure; can avoid the output of air compressor non-compressed air, the normal operation of system be played to safety protection effect.
When especially, the 4th pressure regulation branch road 40 can be used for pneumatic system to overhaul, adjust its air pressure.When pneumatic system is overhauled, can need rig air compressor to have certain working pressure, now can allow the 4th solenoid valve 14 energising, and need to set the 4th pressure regulator valve 24 according to system overhaul, make air compressor output the 4th working pressure, thereby carry out the maintenance of pneumatic system.
Especially, off-load branch road 50 only comprises for controlling the 5th solenoid valve 15 of branch road break-make, and does not comprise for controlling the pressure regulator valve of delivery air pressure.This is because off-load branch road 50 while connecting, and the air pressure of rig air compressor output is pressure unloading, and pressure unloading is only the resistance in pipeline, is air compressor system factory setting, and user can not adjust voluntarily.
In this embodiment, take air-pressure controlling system comprises that five branch roads are described as example.During practical application, can increase as required or reduce branch road in parallel, to meet the demand of system works.
Above embodiment is only illustrative embodiments of the present invention, can not be for limiting the present invention, and protection scope of the present invention is defined by the claims.Those skilled in the art can make various modifications or be equal to replacement the present invention in essence of the present invention and protection domain, these modifications or be equal to replacement and also should be considered as dropping in protection scope of the present invention.
