Description

Technical Field

[0001] The utility model relates to the technical field of industrial refrigeration compressors, in particular to a skid-type super-large screw compressor unit. Background Art

[0002] In the screw compression refrigeration system, the refrigerant is sucked in by the compressor, mixed with the lubricating oil and pressurized into a high-temperature and high-pressure gas. After entering the oil separator, the refrigerant gas is separated and continues to enter the condenser to condense into a high-pressure liquid. After the refrigeration oil is separated, it is filtered, cooled, and pressurized before entering the compressor to lubricate, seal, and cool the compressor. For large screw compressors, the vibration and noise are relatively large. Due to its large gas transmission volume, the vibration and noise of the compressor body and exhaust pipe, including the auxiliary oil pipe, and the economizer pipe are relatively large.

[0003] The existing screw compressor skids include compressors, motors, oil separators and oil circuit systems; there are two general skid layout methods: the screw compressor is located above the oil separator and the screw compressor and the oil separator are arranged in a straight line. For large screw compressor units, if a vertical oil separator is used, the screw compressor and the oil separator are arranged in a straight line; if a horizontal oil separator is used, the compressor is arranged above the oil separator.

[0004] However, if a large screw compressor unit uses a vertical oil separator, the distance between the oil separator and the compressor is about 1 meter, which causes the vibration of the vertical oil separator to be easily transmitted to the exhaust end of the compressor head, causing a series of vibrations from the oil separator to the compressor exhaust pipe and the compressor body; if a horizontal oil separator is used, the compressor is directly installed on the bracket on the oil separator. Since the two are tightly connected in structure, it is very easy to cause resonance that is difficult to predict and solve, so it has limitations. Utility Model Content

[0005] The utility model is developed to solve the above problems and aims to provide a skid-type super-large screw compressor unit.

[0006] The utility model provides a skid-type super-large screw compressor unit, which has the following features: a fixing assembly, the fixing assembly comprising a skid base and a plurality of fixing frames arranged on the skid base; and

[0007] By fixing the compressor mechanism, oil separator, oil pump, filter assembly, and control cabinet mounted on the skid base,

[0008] The compressor mechanism is arranged in parallel with the oil separator. The compressor mechanism includes an oil-injected screw compressor and a compressor motor.

[0009] The filter assembly includes a fine oil filter and a coarse oil filter;

[0010] Among them, an intake pipeline and an exhaust pipeline are provided between the compressor mechanism and the oil separator. The intake pipeline includes an intake pipe, an intake stop valve, an intake check valve, an essential oil filter, and an oil pump. The exhaust pipeline includes an exhaust pipe, an exhaust stop valve, an exhaust check valve, and a coarse oil filter.

[0011] The skid-type super-large screw compressor unit provided by the utility model can also have the following characteristics: the central axis of the oil-injected screw compressor and the compressor motor is parallel to the central axis of the oil separator.

[0012] The skid-type super-large screw compressor unit provided by the utility model can also have the following characteristics: the oil separator is a horizontal, three-stage separation oil separator.

[0013] The skid-type super-large screw compressor unit provided by the utility model can also have the following feature: the installation position of the oil separator is lower than the installation position of the oil-injected screw compressor.

[0014] The skid-type super-large screw compressor unit provided by the utility model can also have the following characteristics: the air intake pipeline and the air exhaust pipeline are also fixedly mounted on the skid base.

[0016] Functions and effects of utility models

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is specifically described in the following embodiments in conjunction with the accompanying drawings.

[0023] Example

[0026] like Figure 1 and Figure 2 As shown, the fixing assembly 10 includes a skid base 11 and a plurality of fixing frames 12 disposed on the skid base 11 .

[0027] In this embodiment, the fixing frame 12 includes a frame-shaped bracket and a steel mounting plate, wherein the frame-shaped bracket is arranged on the skid base 11, and the steel mounting plate is arranged on the frame-shaped bracket, so as to bear the static load and dynamic load of the ultra-large screw compressor unit of the utility model.

[0028] like Figure 1 and Figure 2 As shown, the compressor mechanism 20 includes a compressor mechanism 20, an oil-injected screw compressor 21 and a compressor motor 22, which are both arranged on the skid base 11 through a fixing frame 12. Among them, the central axis of the oil-injected screw compressor 21 and the compressor motor 22 is parallel to the central axis of the oil separator 30.

[0029] like Figure 1 and Figure 2 As shown, the oil separator 30 , the oil pump 40 and the control cabinet 50 are all arranged on the skid base 11 through a fixing frame 12 .

[0030] In this embodiment, the oil separator 30 is a horizontal, three-stage separation oil separator 30 .

[0031] In this embodiment, the oil pump 40 and the control cabinet 50 are both arranged at the edge of the skid base 11 , so that the status of the oil pump 40 and the control cabinet 50 can be easily checked and the control cabinet 50 can be operated.

[0032] In this embodiment, the installation position of the oil separator 30 is lower than the installation position of the oil-injected screw compressor 21. Therefore, the lubricating oil in the compressor can flow freely into the oil separator 30 after shutdown, and will not cause high torque when starting.

[0033] like Figure 1 and Figure 2 As shown, the filter assembly 60 includes a fine oil filter 61 and a coarse oil filter 62, both of which are arranged on the skid base 11 through a fixing frame 12. The removable end caps of the fine oil filter 61 and the coarse oil filter 62 face the walkway, so that it is convenient to replace the filter element. In addition, because the space between the compressor and the oil separator 30 is small, it is necessary to minimize the arrangement of equipment that requires frequent maintenance.

[0034] like Figure 1 and Figure 2 As shown, the intake line 70 includes an intake pipe, an intake stop valve, an intake check valve, a fine oil filter 61 , and an oil pump 40 , and the exhaust line 80 includes an exhaust pipe, an exhaust stop valve, an exhaust check valve, and a coarse oil filter 62 .

[0036] In this embodiment, the utility model skid-type super-large screw compressor unit also includes an oil cooler, a compressor economizer, an oil pump 40 motor, an oil pressure regulating valve, a temperature sensor, a transmitter, and a pressure transmitter, etc.
