Description
Technical field
The utility model relates to air compressor, especially has the double-core air compressor of two separate host and gas holder.
Background technique
Air compressor especially reciprocating-piston air compressor is used widely in various pneumatic equipments because of characteristics such as its pressure and range of flow are big, moderate, adaptability is strong.Its model, specification are numerous, provide bigger range of choice to the user, generally are according to 1.2 to 1.4 times of conducts of the average air consumption of gas equipment selection ground to the air compressor air displacement.But in concrete production practices; the moment of gas equipment, there was big gap in maximum air consumption with average air consumption; cause the factor of this big gap a lot; generally restive; so through regular meeting take place because of maximum air consumption that the air compressor air displacement temporarily can not satisfy gas equipment causes gas equipment can not the continuous effective operation, what just occur usually waits the gas phenomenon.For the air feed bottleneck that solves so produce, several modes below main the employing: the one, increase stand-by compressor; The 2nd, the configuration gas supply station; The 3rd, the jumbo gas holder of device.But these modes have following deficiency: one is all needing certain excessive input to the user aspect the cost; Its two, if adopt first kind of mode, stand-by compressor has long standby time, thereby reduces the overall efficiency of air compressor; Its three, if adopt second kind or the third mode, can be bigger because of the volume of these equipment and deadweight, special factors such as basic fixed also need be carried out in occupied ground and space, make these equipment not possess flowability, in fact, a lot of gas equipments are mobile operational process.
The model utility content
The purpose of this utility model provide a kind of with low cost, efficient is high, compact structure, automaticity height, be convenient to move, the air compressor of air feed continuously.
This double-core air compressor, but comprise the power mechanism of clockwise and anticlockwise, two independently air compression machine hosts and the gas holder that links to each other with main frame, power mechanism connects the input shaft of two air compression machine hosts respectively by automatic directional driving mechanism.
The utility model rotates by the input shaft that automatic directional driving mechanism drives the air compression machine host, and two of drives respectively by the power mechanism clockwise and anticlockwise are the air compression machine host independently, and efficient height, cost are low.
As improvement, after being parallel to two position three-way valve, the air outlet on two gas holder connects gas equipment.By can the selection pressure bigger gas holder of two position three-way valve to the gas equipment air feed, and the bigger gas holder of pressure is in the time of the gas equipment air feed, power mechanism rotates the input shaft that drives with the tank connected air compression machine host of the less gas storage of pressure and rotates, to inflate to the less gas holder of this pressure.After after a while, originally the gas holder that pressure is bigger is because of reducing gradually to its pressure of gas equipment air feed, and simultaneously, originally the less gas holder of pressure raises gradually because of inflating its pressure.When the pressure that is reduced to the less gas holder of certain numerical value and original pressure when the pressure of the bigger gas holder of original pressure is elevated to a numerical value, can be by two position three-way valve transposition and power mechanism counter-rotating, make original not to the gas holder of gas equipment air feed to the gas equipment air feed, and to originally inflating to the gas holder of gas equipment air feed.Therefore, this air compressor is with low cost, utilization efficiency is high, air feed continuously.
Automatic directional driving mechanism belongs to prior art, and the driving shaft of automatic directional driving mechanism is clockwise, when rotating counterclockwise, can carry out power transmission to two separate functional units respectively.Application number is that 200810123943.8 Chinese patent application discloses a kind of automatic directional driving mechanism (comprising coaxial automatic directional driving mechanism and different axle automatic directional driving mechanism), their compact structures, automaticity height.The detailed description of relevant automatic directional driving mechanism sees also described patent application.This automatic directional driving mechanism is used for the utility model, also makes the utility model be convenient to move.
In order to control the automatic clockwise and anticlockwise of power mechanism, as the improvement to above-mentioned air compressor, it also comprises two pressure transducers that detect the gas holder internal pressure, comparator, the control mechanism of control power mechanism clockwise and anticlockwise; Pressure transducer connects the input of comparator, and the output of comparator connects control mechanism; Comparator arrives control mechanism according to the big or small output signal of two gas holder internal pressures that pressure transducer detects, and rotates with the input shaft of control power mechanism drive with the tank connected air compression machine host of the less gas storage of pressure.
In order to control the automatic transposition of two position three-way valve, as the improvement to above-mentioned air compressor, described two position three-way valve is a solenoid valve, and the output of comparator also connects the control circuit that control electromagnetic valve gets dead electricity; The big or small output signal of two gas holder internal pressures that comparator detects according to pressure transducer is to control circuit, with the control electromagnetic valve action, make be connected air outlet on the big gas holder of pressure by solenoid valve to the gas equipment air feed.
