Problems solved by technology

In order to meet these requirements, it is possible to increase the diameter of the cylinder and piston of the compression device to increase its internal volume; however, it will cause problems such as increased volume of the compressor, increased power consumption of the motor, and increased cost.
In addition, in the case of using a plurality of vapor compressors, the installation space of the entire facility becomes larger and there is a problem of an increase in cost

[0055] This is an embodiment that achieves the aforementioned first object of the present invention. Figure 1A is a plan view showing the reciprocating compressor as a whole; Figure 1B is a front view in partial section; Figure 1C is a side view showing a partial section. The reciprocating compressor P1 is composed of four gas compression devices, that is, the first gas compressor 1 , the second gas compressor 2 , the third gas compressor 3 and the fourth gas compressor, which are arranged opposite to each other in a cross shape. The four gas compressors 1 to 4 each have cylinders and pistons, and the difference from the aforementioned existing reciprocating compressors is that the four gas compressors have the same internal volume and compression performance. The piston of the first gas compressor 1 and the piston of the third gas compressor 3 are coaxially connected on one of the yokes; and the piston of the second gas compressor 2 and the piston of the fourth gas compr...

[0066] This example is to achieve the aforementioned second objective of the present invention. Such as Figure 4 As shown, a discharge block 121 is mounted on the discharge port 5 a of the cylinder head 5 of the fourth gas compressor 4 using a fixing bolt 122 . An expansion type muffler is formed at a connection portion of the pressure reducing member 121 to the discharge port 5a. The inside of the expandable muffler pipe 123 is formed by disposing a space S whose inner diameter is larger than the inner diameter of the discharge port 5a of the cylinder head 5, and a discharge port 124 whose inner diameter is smaller than the inner diameter of the space S is formed at the front end. The discharge port 124 is connected to a gas supply pipe not shown in the figure.

[0067] As mentioned above, the gas compressed in the first compressor 1 to the third compressor is sent to the cylinder head on the side of the fourth compressor 4 through the first connecting pipe 6 to the third ...

[0072] This example is an embodiment for achieving the aforementioned third objective of the present invention. Such as Figure 5 As shown, a cylindrical mounting portion 221a is formed at the upper end of a fly wheel 221, and a mounting hole 221b is provided in the axial direction. The cylindrical mounting portion 221a is formed based on the shaft hole 222a of the rotor 222 of the motor 19 ; that is, the outer diameter of the cylindrical mounting portion 221 is consistent with the inner diameter of the shaft hole 222a of the rotor 222 . The flywheel 221 is installed by inserting the aforementioned cylindrical mounting portion 221 into the shaft hole 222a of the rotor 222, making its upper end face contact with the lower end face of the crankshaft 223, and then inserting the fixing bolt 224 into the aforementioned mounting hole 221b so that it is in contact with the lower end face of the crankshaft 223. The screw hole 223a provided in the axial direction of the crankshaft 223...

Abstract

A reciprocating compressor is provided with a plurality of gas compression means having a cylinder and a piston, the piston of each gas compression means is cooperated with the compressor by converting a rotating motion of a crankshaft provided on an electric drive source to a reciprocating motion by a scotch yoke mechanism, wherein an increase of the volume of discharged gas can be achieved without designing a gas compression means to be wide or without increasing the number thereof, a pulsation of discharged gas can be decreased by an attachment of an expansion muffler on the cylinder head so as to decrease a vibration and noise of the compressor, an attachment of the fly wheel to the crankshaft and an adjustment of the shaft with the crankshaft can be improved easily, further compressed gas flows are joined and discharged in concentration, thereby the pulsation of discharged gas can be restrained.

Description

technical field [0001] The invention relates to a reciprocating compressor, which is equipped with a plurality of gas compression devices with cylinders and pistons. The pistons of each gas compressor are converted into reciprocating motion by the rotation of the crankshaft provided on the driving source, and are linked by way to run. Background technique [0002] A general reciprocating compressor is composed of a gas compression device with a cylinder and a piston, but there are also reciprocating compressors with multiple gas compression devices. This type of reciprocating compressor with multiple gas compression devices, such as Figure 9A As shown generally, it has three sets of gas compression devices 101, 102, 103 including cylinders and pistons; on the orthogonal axes 105, 106, the pistons are relatively arranged in a reciprocating manner, and the gas compression device 101 starts to sequentially compress the gas Compression and pressurization, and to the gas compre...
