Description

Technical Field

[0001] The utility model belongs to the technical field of compressors and relates to a high-pressure compressor. Background Art

[0002] A compressor is a driven fluid machine that can lift low-pressure gas to high-pressure gas. It is the heart of the refrigeration system. It is widely used in many industries such as petroleum, chemical industry, electric power, construction engineering, mining, steel, metallurgy, automobile, chemical fiber, pharmaceutical, and food. The motor drives the crankshaft to rotate, and the crankshaft drives the piston to reciprocate in the cylinder through the connecting rod, so that the volume in the cylinder changes periodically, that is, the low-pressure gas is sucked into the cylinder for compression and then discharged from the cylinder, and then discharged from the compressor after cooling and gas-liquid separation. The high-pressure compressor uses a multi-stage compression method based on the ordinary compressor to achieve high-pressure output. At present, it is necessary to install three-stage and four-stage cooling pipelines to convert the existing ordinary compressor into a high-pressure compressor. So how to achieve the laying of three-stage and four-stage cooling pipelines in a limited space is a difficult point for people in this field. Summary of the invention

[0006] The high-pressure compressor is provided with a cooler on the front side of the machine head, and then a cooling coil 1 is provided on the front side of the cooler, so that the cooler and the cooling coil 1 are both located between the cooling fan and the machine head. This makes the structure of the high-pressure compressor more compact, thereby saving installation space and reducing the size of the high-pressure compressor; on the other hand, the wind energy of the cooling fan blows to the cooler, cooling coil 1 and cooling coil 2, and the structure is more reasonable, thereby further improving the cooling effect of the cooler, cooling coil 1 and cooling coil 2. In addition, the size of the high-pressure compressor can also be smaller under the same compression power.

[0007] In the above-mentioned high-pressure compressor, the machine head is provided with a plurality of coil fixing clips along its circumference, and the coil fixing clips are connected to the machine head through a supporting sheet metal, and the cooling coil 2 is coiled on the plurality of coil fixing clips. The machine head is provided with the cooling coil 2 coiled by the plurality of coil fixing clips arranged on its circumference, and the supporting sheet metal can support and position the coil fixing clips and the cooling coil 2, so that the cooling coil 2 can be stably arranged on the outer peripheral side of the cooling fan.

When in use, the gas-liquid separation of the first-stage compression adopts the cyclotron filter, which is small in size and can be used for rough separation of gas and liquid. The gas-liquid separation of the second-stage compression, the third-stage compression and the fourth-stage compression adopts the multi-stage oil-water separator, which can be used for fine separation of gas and liquid, and the gas-liquid separation effect is good.

The sum of the number of coolers and cooling coils is determined according to the number of cylinders. In order to make the structure of the high-pressure compressor more compact, the first-stage cylinder and the second-stage cylinder of the high-pressure compressor are cooled by coolers, and the third-stage cylinder and the fourth-stage cylinder are cooled by cooling coils. The coolers are spaced apart in the height direction of the machine head, and one of the cooling coils is arranged at the front side of the cooler and located between the cooling fan and the machine head, and the other cooling coil is arranged on the outer peripheral side of the cooling fan.
