Description

Technical Field

[0001] This utility model relates to the field of fluid machinery technology, specifically to a direct-drive high-efficiency piston compressor. Background Technology

[0002] A reciprocating compressor is a type of compressor that uses the reciprocating motion of a piston to pressurize and transport gas. It is a positive displacement compressor, also known as a "reciprocating piston compressor" or "reciprocating compressor." It mainly consists of a working chamber, transmission components, a casing, and auxiliary components. The working chamber is directly used to compress gas and consists of a cylinder, cylinder liner, valves, packing, piston, and piston rod. The piston, driven by the piston rod, reciprocates within the cylinder. The volumes of the working chambers on either side of the piston alternately change in opposite directions. On the side with a smaller volume, gas is discharged through the valve due to increased pressure, while on the side with a larger volume, gas is drawn in through the valve due to decreased pressure. The transmission components, used to achieve the reciprocating motion, include crankshaft connecting rods, eccentric sliders, and swashplates, among others. The crankshaft connecting rod mechanism is the most common, consisting of a crosshead, connecting rod, and crankshaft.

[0003] Existing piston compressors generally employ a crankshaft connecting rod mechanism. When the crankshaft rotates, it generates periodic centrifugal force, resulting in severe vibration of the entire machine. The long-stroke design leads to large lateral forces on the piston, significant cylinder wall wear, and the added mass of the counterweight increases the overall weight by more than 30%. Furthermore, it cannot eliminate the problem of second-order inertial forces. Improvement solutions attempting to use linear motor drives also suffer from low thrust density, making it difficult to meet the thrust requirements of large cylinders. Direct drive leads to a surge in motor power demand and inconvenient disassembly and assembly of parts. Therefore, a direct-drive high-efficiency piston compressor is needed to solve the above problems. Utility Model Content

One end of the piston 10 is vertically fixed to the connecting sleeve 9, and the connecting rod 11 is slidably inserted into the inner wall of the connecting sleeve 9. The outer side of the connecting sleeve 9... The first end of the connecting rod 11 is connected to the second fixing bolt 14. The other end of the connecting rod 11 is fixedly connected to the driven rack 3 and the driving rack 6, respectively. A transmission gear 8 meshes between the driven rack 3 and the driving rack 6. The driven rack 3 and the driving rack 6 are connected to the first cylinder 1 and the second cylinder 2 via the transmission gear 8 in a meshing transmission and telescopic connection. The phase difference between the movement of the driven rack 3 and the driving rack 6 is 180°, allowing for coordinated meshing and telescopic adjustment, resulting in better operating efficiency. The driven rack 3 and the driving rack 6 are slidably connected to the connecting sleeve 9 via the connecting rod 11, and the connecting rod 11 is bolted to the connecting sleeve 9 via the second fixing bolt 14. This allows the driven rack 3 and the driving rack 6 to... For easy extension, disassembly, and adjustment, and convenient replacement, a first fixing bolt 12 is inserted and connected to the middle of the front side of the active rack 6. A bolt seat 13 is fitted onto the outer wall of the first fixing bolt 12. A connecting slider 20 is fixedly connected to one side of the bolt seat 13, and a transmission groove plate 7 is slidably connected between the connecting sliders 20. The transmission groove plate 7 is bolted to the active rack 6 via the first fixing bolt 12 and bolt seat 13.

The connecting sliders 20 are bolted to the connecting groove 18 via a third fixing bolt 19. This design allows for easy independent bolt disassembly and assembly of the transmission groove plate 7, and enables adjustment of its sliding position, enhancing its adaptability. Even better, the transmission groove plate 7 has splicing grooves 18 on both sides, and the splicing grooves 18 and the upper ends of the splicing slider 20 are connected by a third fixing bolt 19.

[0021] Working principle: When using this direct-drive high-efficiency piston compressor, the device is first assembled and installed. During use, the motor 5 drives the transmission connecting rod 4 to rotate, which in turn drives the transmission slider 15 to reciprocate on the transmission slot plate 7 through the roller groove 16 and the ball bearing 17. This drives the active rack 6 to extend and retract, and then drives the driven rack 3 to extend and retract through the transmission gear 8, thus achieving stable direct-drive piston operation. When the driven rack 3 and the active rack 6 need to be disassembled, they can be disassembled by inserting the connecting rod 11 and the second fixing bolt 14. When the position of the transmission slot plate 7 needs to be adjusted, it can be adjusted by sliding the splicing groove 18 and the splicing slider 20. This is the usage process of the direct-drive high-efficiency piston compressor.
