[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. In this invention, the electric push rod drives the sealing slide to move upward, and the increased clearance volume provides sufficient buffer space for the connecting rod piston unit to move to its limit position. This effectively avoids rigid collision between the connecting rod piston unit and the cylinder head caused by manufacturing errors, thermal expansion, or sudden changes in operating conditions, reduces the risk of scratches on the inner wall of the cylinder liner, and reduces pressure changes inside the cylinder liner. This reduces wear on the valve plates and piston rings inside the connecting rod piston unit, and improves the stability of the entire machine operation. This device can adjust the compressor discharge volume within a small range, allowing the compressor discharge volume to vary stepwise within the rated value range, accurately matching the stepped demand of different load conditions downstream, and thus enabling the equipment to meet refined operating requirements.

[0017] 2. In this invention, only the first spring works during the initial intake phase, achieving low-resistance and rapid opening, ensuring that fresh air flows smoothly into the cylinder liner, effectively shortening the intake lag time and improving intake efficiency. During the compression stroke, the combined stiffness of the first and second springs forms a high-stiffness closing driving force, which can quickly push the valve plate to tightly fit the outlet seat, effectively blocking the backflow of high-pressure residual gas inside the cylinder liner, completely eliminating backflow loss, and avoiding valve plate oscillation. This achieves a rapid balance effect of high-pressure hard closing and low-pressure soft opening, enabling the equipment to achieve a dynamic matching effect between preload and clearance conditions.

[0018] 3. In this invention, the L-shaped plate drives the gear, ring block, fixed frame, fixed rod and adjusting plate to rotate through the rack and pinion, so that the blades are distributed in a spiral shape. When the high temperature and high pressure oil-gas mixture flows through the gas outlet, the spiral blades can guide the airflow to form a strong swirling flow field. The centrifugal force is used to efficiently separate the lubricating oil particles in the oil-gas mixture, which helps to reduce the consumption cost of lubricating oil and reduce the pollution of the gas storage tank and downstream gas-using equipment by lubricating oil.

[0019] 4. In this invention, the equipment achieves different load conditions by dynamically adjusting the clearance volume, adaptively matching the stiffness of the intake valve spring, and strengthening the centrifugal separation of oil and gas at the exhaust port. This significantly improves the stability of the equipment's operation, extends the life of the core components, and enables fine-grained step adjustment of the equipment's exhaust volume, thereby improving the overall performance of the equipment during use.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figures 1-8The present invention provides a technical solution: an energy-saving air compressor, comprising an air tank 1 and a mounting base 2 installed on the top of the air tank 1, wherein a connecting rod seat 3 is fixedly connected to the top of the mounting base 2, and further comprising: Cylinder liner 4 is fixedly connected to the top of connecting rod seat 3, and two cylinder liners 4 are provided; Cylinder liner 4 is fixedly connected to the top of cylinder liner 4, and a cavity is opened in the center of the cylinder liner 4. One side of the cylinder liner 4 is connected to an air inlet 10, and an air outlet seat 12 is provided on the top side inside the air inlet 10. The other side of the cylinder liner 4 is connected to an air outlet 11. The clearance volume adjustment assembly 7 includes a connecting seat 701 fixedly connected to the top of the cylinder liner 4. An electric push rod 702 is fixedly connected to the top of the connecting seat 701. One end of the output shaft of the electric push rod 702 extends into the cavity and is fixedly connected to a sealing slide 703. It is used to drive the sealing slide 703 to move up and down through the electric push rod 702 to achieve the variable working condition energy saving requirements of the equipment. The air inlet adjustment component 8 is located inside the air inlet 10 and is used to adaptively adjust the gas entering the air inlet 10 according to the operating conditions of the clearance volume adjustment component 7. The outlet separation component 9 is installed inside the outlet 11 and is used to adjust the oil-gas separation effect of the outlet 11 according to the operating conditions of the clearance volume adjustment component 7. Also includes: The bottom of the air inlet 10 and the air outlet 11 are connected to the cylinder liner 4. A first through hole 16 is provided between the air inlet 10 and the cavity, and a second through hole 17 is provided between the air outlet 11 and the cavity. The two air outlets 11 are connected to the same external pipe 13 on the side away from the cavity. The other end of the external pipe 13 is connected to the air storage tank 1 through the gas-liquid separator 14. A one-way valve plate is provided on the side of the air outlet 11 opposite to the external pipe 13. The sealing slide 703 is slidably sealed inside the cavity, and the height of the sealing slide 703 is greater than the height of the first through hole 16 and the second through hole 17.

[0024] Detailed Implementation: First, place the equipment in a suitable position and connect the air inlet 10 to the external air filter unit via a flange seal. Based on the pressure and flow requirements of the downstream air-consuming equipment, set the operating parameters of the drive unit 6 and start it. The rotational power output by the drive unit 6 drives the connecting rod piston unit 15 to perform reciprocating linear motion within the cylinder liner 4. When the connecting rod piston unit 15 moves downward, a negative pressure is formed inside the cylinder liner 4. External low-pressure, low-temperature air enters the cylinder liner 4 through the external air filter unit and the air inlet 10. During the upward movement of the connecting rod piston unit 15, the external low-pressure, low-temperature air is compressed into high-temperature, high-pressure gas and transported to the air storage tank 1 through the air outlet 11, the external pipe 13, and the gas-liquid separator 14. At this time, the clearance volume between the sealing slide 703 and the connecting rod piston unit 15 is within the set position. At this time, multiple blades... The plates 908 are arranged in a spiral shape. With the long-term use of the equipment, the electric push rod 702 can be activated as needed to drive the sealing slide 703 upward. The increased clearance volume provides sufficient buffer space for the connecting rod piston unit 15 to move to the limit position, effectively avoiding rigid collision between the connecting rod piston unit 15 and the cylinder head 5 due to manufacturing errors, thermal expansion or sudden changes in operating conditions. This reduces the risk of scratches on the inner wall of the cylinder liner 4 and reduces pressure changes inside the cylinder liner 4, thereby reducing wear on the valve plate 807 and the piston rings inside the connecting rod piston unit 15, and improving the stability of the whole machine operation. This device can adjust the compressor discharge volume within a small range, so that the compressor discharge volume changes stepwise within the rated value range, accurately matching the stepwise demand of different load conditions of low, medium and high downstream, thereby enabling the equipment to meet the refined operating conditions.

[0025] The air intake adjustment assembly 8 includes: T-shaped seat 801 is set at the bottom of the air outlet seat 12, and the bottom of T-shaped seat 801 is fixedly connected to the inner wall of cylinder head 5 through fixed seat 802. An inner cavity is opened at the center of T-shaped seat 801, and a sliding cavity is opened at the junction of T-shaped seat 801 and fixed seat 802. The sliding cavity is connected to the first through hole 16. The first spring 803 is disposed on the bottom side inside the inner cavity, and a sliding seat 804 is fixedly connected to the top of the first spring 803, and the sliding seat 804 is slidably connected inside the inner cavity. An annular sleeve 805 is slidably connected inside the T-shaped seat 801, and the bottom of the annular sleeve 805 is fixedly connected to the top of the sliding seat 804. An annular seat 806 is fixedly connected to the top of the annular sleeve 805. Valve plate 807 is disposed at the bottom of the air outlet seat 12, and the bottom of valve plate 807 is fixedly connected to the top of the annular seat 806; Two connecting rods 808 are arranged in a circular array at the bottom of the annular seat 806, and the connecting rods 808 are slidably connected inside the sliding cavity; The annular plate 809 is slidably connected inside the sliding cavity, and the annular plate 809 is located below the connecting rod 808; The second spring 810 is disposed inside the sliding cavity, and the top end of the second spring 810 is fixedly connected to the bottom of the annular plate 809. The bottom end of the second spring 810 is fixedly connected to a connecting plate 811, which is slidably connected inside the sliding cavity. The second spring 810 is disposed on the outer periphery of the first spring 803. Two connecting brackets 812 are fixedly connected at one end to both sides of the connecting plate 811, and the other end of the connecting bracket 812 extends into the cavity and is fixedly connected to a horizontal plate 813. The horizontal plate 813 is fixedly connected to the outer periphery of the output shaft of the electric push rod 702, and the connecting bracket 812 is slidably connected inside the first through hole 16.

[0026] Detailed Implementation: The electric push rod 702 drives the L-shaped plate 901 and the connecting frame 812 upward via the horizontal plate 813. During the upward movement of the connecting frame 812, the second spring 810 is driven upward via the connecting plate 811 to assist in adjusting the compression stiffness of the second spring 810 during use. When the connecting rod piston unit 15 moves downward and draws external gas through the air inlet 10, the internal pressure of the cylinder liner 4 is greater than the external pressure in the initial stage of intake, causing the valve plate 807 to open. External gas is delivered to the inside of the cylinder liner 4 through the exhaust seat 12. During the opening process, the valve plate 807 drives the connecting rod 808, the annular sleeve 805, and the sliding seat 804 downward via the annular seat 806, and first compresses the first spring 803 to achieve low-resistance and rapid opening, ensuring that fresh air flows smoothly into the cylinder liner 4. Internally, it effectively shortens the intake lag time and improves intake efficiency. As the connecting rod 808 moves downward, it will squeeze with the second spring 810, which adjusts the compression stiffness. In the initial stage of compression, the stiffness of the first spring 803 and the second spring 810 are superimposed to form a high-stiffness closing driving force, which can quickly push the valve plate 807 to fit tightly against the outlet seat 12, effectively blocking the backflow of high-pressure residual gas inside the cylinder liner 4, completely eliminating backflow loss, and avoiding the oscillation of the valve plate 807, ensuring the stability of the intake airflow. In the initial stage of intake, only the first spring 803 works, reducing the opening resistance. During the compression stroke, the combined action of the first spring 803 and the second spring 810 quickly prevents the backflow of residual gas, achieving a rapid balance effect of high-pressure hard closing and low-pressure soft opening, and realizing the dynamic matching effect of preload and clearance conditions.

[0027] The outlet separation component 9 includes: The L-shaped plate 901 is fixedly connected to the outer wall of the horizontal plate 813 on one side, and the rack 902 is fixedly connected to the other end of the L-shaped plate 901. The L-shaped plate 901 is slidably connected inside the second through hole 17. Gear 903 is meshed with one side of rack 902, and an annular block 904 is fixedly connected to the inner circumference of gear 903. Fixing brackets 905 are fixedly connected to both sides of the annular block 904, and fixing rods 906 are fixedly connected to the side of the two fixing brackets 905 away from the annular block 904. The fixed sleeve 907 is sleeved on the outer periphery of the fixed rod 906, and the fixed sleeve 907 is fixedly connected to the inner wall of the cylinder head 5 through the support frame. The support frame is set on the side opposite to the outer pipe 13. A recovery oil ring is set on the side of the fixed sleeve 907 away from the support frame. Multiple arc-shaped through holes are distributed in an equidistant array inside the fixed sleeve 907. Multiple blades 908 are equidistantly distributed on the outer periphery of the fixed sleeve 907, and a fixed plate 910 is fixedly connected to the inner periphery of the blades 908. The fixed plate 910 is slidably connected inside the arc-shaped through hole, and the blades 908 are rotated and sealed on the outer periphery of the fixed sleeve 907. Multiple adjusting plates 909 are disposed on one side of multiple fixed plates 910, and the adjusting plates 909 are spirally distributed on the outer periphery of the fixed rod 906; Also includes: The drive unit 6 is located on one side outside the connecting rod seat 3, and one end of the output shaft of the drive unit 6 is connected to the connecting rod piston unit 15. The connecting rod piston unit 15 is rotatably connected inside the connecting rod seat 3, and the connecting rod piston unit 15 is slidably sealed inside the cylinder liner 4.

[0028] Detailed Implementation: The L-shaped plate 901 synchronously drives the rack 902 to move upward. Utilizing the linkage effect between the rack 902 and the gear 903, power is transmitted to the gear 903, causing the gear 903 to rotate through the annular block 904, the fixed frame 905, the fixed rod 906, and the adjusting plate 909. This causes the adjusting plate 909 to gradually contact the fixed plate 910, which in turn drives the blades 908 to rotate, further increasing the spiral distribution angle of the blades 908. When the high-temperature, high-pressure oil-gas mixture flows through the outlet 11, the spiral blades 908 can guide the airflow to form a strong swirling flow field, using centrifugal force to efficiently separate the lubricating oil particles in the oil-gas mixture, assisting in reducing... This equipment reduces lubricant consumption costs and minimizes lubricant contamination of the gas storage tank and downstream gas-using equipment. Through integrated design of dynamic clearance volume adjustment, adaptive matching of intake valve spring stiffness, and enhanced centrifugal separation of oil and gas at the exhaust port, it can meet the needs of different load conditions with one adjustment, significantly improving the operational stability of the equipment, extending the life of core components, and enabling fine-grained step adjustment of the exhaust volume, thereby improving the overall performance of the equipment during use. The blades 908 can be set on the outer periphery of the fixed sleeve 907 through a limiting mechanism as needed, and the operating angle of the blades 908 can be set according to actual needs. Furthermore, two sets of multiple adjustment plates 909 can be provided.
