Detailed Description
As shown in fig. 1, the lead screw type gas compression system with adjustable flow and pressure comprises a gas compression cylinder 6 and a lead screw driving structure for driving the gas compression cylinder 6, wherein the lead screw driving structure comprises a lead screw 2, the lead screw 2 is connected with a driven adjustable speed motor 1, when the adjustable speed motor 1 rotates, the lead screw 2 connected on the adjustable speed motor 1 rotates to drive a sliding block 5 to compress and stretch acting force on the gas compression cylinder 6 along the direction of a stabilizer bar 4. Therefore, the whole gas compression system has the advantages of stability, high pressure, energy conservation, silence and the like during operation, and the flow and the pressure of the compression system can be conveniently controlled by controlling the speed of the speed regulating motor 1.
Because the gas compression cylinder 6 generates acting force on the sliding block 5 in the compression process, the gas compression cylinder 6 may bend and deform in the compression process, and in order to solve the problems, the stabilizer bar 4 is arranged in the parallel direction of the screw rod 2, and the stabilizer bar 4 and the screw rod 2 form three supporting points on the same plane, so that the effect of stability and firmness is achieved.
In order to improve the work efficiency of the gas compression cylinders 6, the two groups of gas compression cylinders 6 are respectively arranged at two sides of the sliding direction of the sliding block 5, the two groups of gas compression cylinders 6 are connected with the sliding block 5 through a connecting rod, and when the sliding block 5 compresses towards one gas compression cylinder 6, the gas compression cylinders 6 are exhausted. At the same time, the other gas compression tube 6 performs the drawing operation, and the gas compression tube 6 performs the suction operation. The two gas compression cylinders 6 perform complementary actions to provide continuous compressed gas.
When the 1 rotational speed of buncher is slow, lead screw 2 is in slow rotation to make slider 5 slow to the effort of a gas compression section of thick bamboo 6, because the rotational speed is slow, the gas inflow and the gas outlet flow of a gas compression section of thick bamboo 6 are few, when the 1 rotational speed of buncher accelerates, the rotation of lead screw 2 accelerates, thereby makes slider 5 accelerate the effect of a gas compression section of thick bamboo 6, and the gas inflow and the gas outlet of a gas compression section of thick bamboo 6 accelerate, and the flow becomes more. Thereby, the change of the gas flow is changed by adjusting the rotating speed of the motor 1.
When the stroke time of the positive and negative rotation of the speed regulating motor 1 is increased, the linear stroke of the sliding block 5 is increased, the compression of the sliding block 5 on the gas compression cylinder 6 is increased, and the pressure of gas output is also increased due to the increase of the compression of the gas compression cylinder 6. When the forward and reverse rotation travel time of the speed regulating motor 1 is reduced, the linear travel of the slide block 5 is shortened, the compression of the slide block 5 on the gas compression cylinder 6 is reduced, and the pressure output by gas is correspondingly reduced due to the reduction of the compression of the gas compression cylinder 6.
