The working process of the four-stage W-type high-pressure compressor of the present utility model is:

When the first-stage and second-stage conjoined pistons move from the side of the first-stage cylinder head 22 to the side of the crankshaft 54, the working volume of the first-stage cylinder increases, the pressure in the cylinder is lower than the external pressure, and the outside air passes through the air filter in the air filter assembly 9.

With the rotation of the crankshaft 54, when the piston moves from the side of the crankshaft 54 to the side of the primary cylinder head 22, the primary suction valve is closed, the working volume of the primary cylinder gradually decreases, and the gas in the cylinder is compressed for the first time.

The compressed gas cooled by the cooler enters the oil-water separator to separate the water and oil mixed in the gas, and the separated compressed gas enters the second stage of the primary and secondary compression system 3 through the primary safety valve and the secondary air intake pipe 18 In the compression system, the first-stage and second-stage conjoined pistons move from the side of the crankshaft 54 to the side of the first-stage cylinder head. With the rotation of the crankshaft 54, when the first-stage and second-stage conjoined pistons move from the side of the first-stage cylinder head 22 to the side of the crankshaft 54, the second-stage suction valve is closed, and the working volume of the second-stage cylinder gradually decreases, and the compression in the cylinder The gas is compressed for the second time, and the pressure rises again. When the pressure reaches a certain value, the secondary exhaust valve is pushed open. When the gas is compressed, the temperature also increases, and the compressed gas enters the secondary radiator 8 through the pipeline.

The compressed gas cooled by the cooler enters the oil-water separator again, and the separated compressed gas enters the three-stage compression system 17 through the secondary safety valve and the three-stage intake pipe 13. Moving toward the side of the crankshaft 54, the three-stage intake valve is opened, while the three-stage exhaust valve is closed, and the compressed gas enters the three-stage cylinder block 34. With the rotation of the crankshaft 54, when the piston moves from the side of the crankshaft 54 to the side of the third-stage valve seat gland 37, the third-stage intake valve is closed, the working volume of the third-stage cylinder gradually becomes smaller, and the compressed gas in the cylinder undergoes the first stage.

The four-stage W-type high-pressure compressor of the utility model has the following advantages:

(1) Significantly save the mechanical work of compressing gas.

The product has a four-stage cooling process, which makes the compression process close to isothermal compression. After compression, the density of the gas increases, and after the heat is released, the enthalpy value decreases, which improves the efficiency of compressed air.

(2) It can effectively reduce the exhaust temperature.

The cooling device in the middle of the four-stage compression reduces the intake temperature of the gas, which can significantly reduce the exhaust temperature. The temperature of the exhaust gas of the compressor increases with the increase of the compression ratio. The higher the compression ratio, the higher the exhaust temperature. If the temperature of the lubricating oil is too high, the viscosity will be reduced, and the wear will be aggravated. In addition, it is easy to form in the cylinder and on the valve. Carbon deposits, increased wear, and sometimes even explosions. Through the four-stage cooling device, the exhaust temperature is reduced, which greatly improves the safety and service life of the machine.

(3) Significantly increase the volume factor.

As the pressure ratio rises, the volume occupied by the gas expansion in the clearance volume increases, and the actual suction volume of the cylinder decreases. With four-stage compression, the pressure ratio decreases, so the volume coefficient increases, thereby improving the utilization rate of the volume.

(4) Reduce the piston force.

If single-stage compression is used, the higher terminal air pressure always acts on a larger piston area. Through four-stage compression, the gas pressure increases step by step, while the diameter of the cylinder decreases step by step. The gas pressure acting on the large piston area is small, and the high pressure stage is that the higher gas pressure acts on the smaller piston area, so the force acting on the moving mechanism at each stage is significantly reduced. Therefore, the weight of the kinematic mechanism is reduced and the efficiency of the machine is improved.

(5) The mechanical structure is simplified.

The one-stage piston and two-stage piston conjoined structure is adopted, which simplifies the mechanical structure, reduces moving parts, improves the reliability of the machine, and reduces the production cost at the same time.

It is not difficult for those skilled in the art to understand that the four-stage W-type high-pressure compressor of the present invention includes any combination of parts in this specification. Due to space limitation and in order to make the specification concise, these combinations are not introduced in detail here, but after reading this specification, the scope of the utility model constituted by any combination of the parts of this specification is self-evident.
