The principle of this programme: when specifically using, when passing into compressed gas source in pressure cylinder, pressure durations in pressure cylinder raises, compressed gas source promotes piston and moves, piston driving piston cylinder moves and piston rod is released pressure cylinder simultaneously, pressure in the real-time detected pressures cylinder of gas pressure sensor, and pressure is vertically sent to controller, after the gas pressure in pressure cylinder is constant, when the pressure value that gas pressure sensor detects is stablized, controller controls electric control valve and opens, now the source of the gas of pressure cylinder passes into pressurized gas in pneumatic tube, pressurized gas sprays from jet mechanism, dust on piston rod is blown away.
The advantage of this programme is: in this programme, have additional cleaning structure, automatically controlled by gas pressure sensor and controller, carry out jet by jet mechanism to the piston rod stretching out pressure cylinder, the dust being attached to piston rod surface is blown away, so just can reduce the dust of the adhesion of piston rod surface, in piston rod and the frequent friction process of pressure cylinder, because there is no dust attachment on the piston rod, so piston rod and seal guide sleeve rub less, piston rod and seal guide sleeve is not easily caused to damage, without the need to frequent maintenance, thus extend the working life of air spring.
Optimized project 1, to the further optimization of base case, described jet mechanism is blast nozzle, and the direction of pressure cylinder is stretched out in the jet direction of this blast nozzle towards piston rod.The gas pressure sprayed by blast nozzle is high, can effectively be blown away by the dust that piston rod surface adheres to.
Optimized project 2, to the further optimization of base case, described jet mechanism is air jet pipe cylindrically, cavity is provided with in air jet pipe, air jet pipe is offered the suction port be communicated with cavity, this suction port is connected with pneumatic tube, is enclosed within piston rod near cylinder side outside described air jet pipe, and air jet pipe inwall is offered the fumarole that some and described cavity is communicated with.During use, the gas in pneumatic tube enters in cavity through suction port, finally from fumarole ejection, due to air jet pipe be overcoat on the piston rod, the gas sprayed by fumarole can be blown in piston rod circumference, does not clear up dead angle, blows away the better effects if of dust.
Optimized project 3, to the further optimization of optimized project 2, described fumarole is in tilted layout, and stretches out the side of pressure cylinder towards piston rod.When fumarole is in tilted layout in a manner described, the power that the gas of blowout acts on piston rod surface is also tilt, and can directly blow off dust piston rod like this.
Optimized project 4, to the further optimization of base case, any one of optimized project 1-3, described electric control valve is solenoid valve.Solenoid valve has response rapidly, controls sensitive feature, is convenient to accurate control.
