Description

Technical Field

[0001] This utility model relates to the field of fluorine pump system technology, and in particular to a liquid receiver for fluorine pumps, a fluorine pump compressor, and a fluorine pump system. Background Technology

[0002] In data centers or communication equipment rooms, systems need to operate year-round. When the ambient temperature is lower than the indoor temperature, utilizing outdoor cooling sources can achieve energy conservation and emission reduction. This necessitates the use of various types of refrigerant pumps to stabilize the room temperature. A refrigerant pump refrigeration cycle primarily utilizes a refrigerant pump to drive liquid refrigerant through a natural cooling process. Liquid is drawn from the receiver, flows into the compressor pump body, undergoes compression, and finally exits from the drain port.

[0003] In the industry, gear pumps and centrifugal pumps are the most common types of pumps for conveying liquid refrigerants. However, their high manufacturing costs and low overall efficiency have hindered the industry's development. To address these issues, combining pumps with positive displacement rotary pumps can reduce costs and improve efficiency. Furthermore, the design of the liquid receiver structure in positive displacement rotary pumps has a significant impact on efficiency improvement.

[0004] The existing liquid receiver consists of a bend, intermediate pipe, upper cylinder, lower cylinder, suction pipe, intermediate cylinder, filter screen, and baffle. It is installed vertically. The refrigerant pump compressor suction has no buffer, resulting in large pulsation and high flow resistance. Moreover, the vertical installation requires additional piping to connect to the liquid receiver's suction port. The compressor piping is long, and the large liquid pulsation during refrigerant pump circulation leads to large piping vibration, affecting the stable operation of the refrigerant pump. Secondly, the vertical installation of the liquid receiver and the bend connection to the compressor cause eddies to be generated at the bend when the liquid refrigerant flows to the compressor, increasing refrigerant pulsation and thus causing large vibration. Utility Model Content

[0005] The purpose of this invention is to provide a liquid receiver for a fluorine pump, a fluorine pump compressor, and a fluorine pump system, to solve the technical problem in the prior art where the fluorine pump liquid receiver is vertically installed and connected to the compressor via a bend in the pipe, resulting in significant vibration. The preferred technical solutions provided by this invention offer numerous technical advantages, which are detailed below.

[0006] To achieve the above objectives, the present invention provides the following technical solution: The liquid storage device for fluorine pumps provided by this utility model includes a liquid storage body, which is arranged horizontally, and a suction pipe and a discharge pipe are respectively arranged on both sides of the liquid storage body in the horizontal direction. The outlet pipe includes a connecting pipe and two dispensing pipes. One end of the connecting pipe is connected to the main body of the liquid reservoir, and the two dispensing pipes are located at the other end of the connecting pipe, and the two dispensing pipes are distributed in a U-shape.

[0007] As an optional implementation, the diameters of the suction tube, the connecting tube, and the two dispensing tubes are all smaller than the inner diameter of the main body of the reservoir.

[0008] As an optional implementation, both of the liquid separators are provided with a flow-retarding tube at their outlet ends.

[0009] As an optional implementation, the slow-flow tube is an S-shaped tube.

[0010] As an optional implementation, both outlet ends of the slow-flow pipe are provided with horizontal sections, which are horizontally positioned and have a gradually decreasing diameter from the slow-flow pipe towards both ends.

[0011] As an optional implementation, the end diameter of the horizontal section is the same as the diameter of the dispensing tube.

[0012] As an optional implementation, the suction tube includes an expanding straight tube section and a fixed straight tube section. One end of the fixed straight tube section is connected to the expanding straight tube section, and the other end of the fixed straight tube section is connected to the liquid reservoir body. The diameter of the expanding straight tube section is larger than the diameter of the fixed straight tube section.

[0013] As an optional implementation, the liquid reservoir body includes a horizontally placed cylinder, and a filter screen is disposed inside the horizontally placed cylinder.

[0014] As an optional implementation, the horizontal cylindrical body includes an upper cylindrical body, an intermediate cylindrical body, and a lower cylindrical body, wherein the upper cylindrical body and the lower cylindrical body are connected to both ends of the intermediate cylindrical body; and / or, the horizontal cylindrical body is integrally formed.

[0015] A fluorine pump compressor includes a compressor body and a fluorine pump receiver as described above. The compressor body is vertically arranged, and the two distribution pipes are connected to the compressor body.

[0016] A fluorine pump system, comprising a fluorine pump compressor as described above.

[0017] The beneficial effects of this utility model are as follows: The liquid receiver, compressor, and pump system for fluorine pumps provided by this utility model include a liquid receiver body, which is arranged horizontally. A suction pipe and an outlet pipe are respectively arranged on both sides of the liquid receiver body in the horizontal direction. Liquid refrigerant enters the liquid receiver body from the suction pipe and flows into the compressor pump body from the outlet pipe. After compression, it is discharged from the compressor outlet. The outlet pipe includes a connecting pipe and two distribution pipes. One end of the connecting pipe is connected to the liquid receiver body, and the two distribution pipes are arranged at the other end of the connecting pipe in a U-shape. The two distribution pipes can be directly connected to the compressor inlet, allowing refrigerant to flow from the liquid receiver body. The refrigerant flows into the compressor pump body through a connecting pipe and two U-shaped distribution pipes, avoiding the problems of eddy currents and increased refrigerant pulsation leading to excessive vibration that are easily generated by using bent pipe connections. Secondly, the refrigerant receiver body is arranged horizontally, so the refrigerant pump system does not need to add an extra pipeline to connect to the suction pipe of the receiver body. The compressor pipeline is short, reducing vibration during refrigerant pump circulation and ensuring stable operation of the refrigerant pump. In addition, the two distribution pipes are distributed in a U-shape. After the refrigerant passes through the connecting pipe, the cross-section increases when it passes through the middle of the U-shape before entering the two distribution pipes, forming a variable cross-section that changes from small to large and then back to small. This effectively buffers the refrigerant flow pulsation and effectively reduces vibration and suction noise. Attached Figure Description

[0024] This invention provides a liquid receiver, compressor, and system for fluorine pumps that effectively reduce vibration and intake noise.

[0025] The following is combined with Figures 1-9 The technical solution provided by this utility model will be described in more detail.

[0026] This utility model provides a liquid reservoir 100 for a fluorine pump, including a liquid reservoir body 110, which is arranged horizontally, and a suction pipe 120 and a discharge pipe 130 are respectively arranged on both sides of the liquid reservoir body 110 in the horizontal direction. The liquid outlet pipe 130 includes a connecting pipe 131 and two distributing pipes 132. One end of the connecting pipe 131 is connected to the liquid reservoir body 110, and the two distributing pipes 132 are disposed at the other end of the connecting pipe 131, and the two distributing pipes 132 are distributed in a U-shape.

[0027] The present invention provides a liquid receiver 100 for a refrigerant pump, comprising a receiver body 110, which is arranged horizontally. A suction pipe 120 and an outlet pipe 130 are respectively arranged on both sides of the receiver body 110 in the horizontal direction. Liquid refrigerant enters the receiver body 110 from the suction pipe 120 and flows into the compressor pump body from the outlet pipe 130. After compression, it is discharged from the compressor discharge port. The outlet pipe 130 includes a connecting pipe 131 and two distributing pipes 132. One end of the connecting pipe 131 is connected to the receiver body 110, and the two distributing pipes 132 are arranged at the other end of the connecting pipe 131 in a U-shape. The two distributing pipes 132 can be directly connected to the compressor inlet. Refrigerant flows from the receiver body 110 through the connecting pipe 131... The refrigerant flows into the compressor pump body through pipe 131 and the two U-shaped distribution pipes 132, avoiding the problems of eddy currents and increased refrigerant pulsation leading to large vibrations that are easily generated by using bent pipe connections. Secondly, the liquid receiver body 110 is arranged horizontally, which can be directly connected to the two components of the refrigerant pump system. The refrigerant pump system does not need to add additional pipelines to connect to the liquid suction pipe 120 of the liquid receiver body 110. The compressor pipeline is short, reducing refrigerant flow resistance, reducing vibration during refrigerant pump circulation, and ensuring stable operation of the refrigerant pump. In addition, the two distribution pipes 132 are distributed in a U-shape. After the refrigerant passes through the connecting pipe 131, the cross-section increases when it passes through the middle of the U-shape, and then enters the two distribution pipes 132, forming a variable cross-section that changes from small to large and then back to small. This can effectively buffer the refrigerant flow pulsation and effectively reduce vibration and suction noise.

[0028] In some embodiments of this utility model, the suction tube 120 includes an expanding straight tube section 121 and a fixed straight tube section 122. One end of the fixed straight tube section 122 is connected to the expanding straight tube section 121, and the other end of the fixed straight tube section 122 is connected to the liquid reservoir body 110. The diameter of the expanding straight tube section 121 is larger than the diameter of the fixed straight tube section 122.

[0029] In some embodiments of the present invention described above, the liquid suction pipe 120 includes an expanding straight pipe section 121 and a fixed straight pipe section 122.

The liquid refrigerant enters the liquid receiver body 110 after passing through the expanding straight pipe section 121 and the fixed straight pipe section 122 in sequence. The change in cross-section from large to small and then back to large effectively buffers the flow pulsation of the liquid refrigerant, effectively reducing vibration and suction noise.

[0030] In some embodiments of this utility model, the liquid reservoir body 110 includes a horizontally placed cylindrical body 111, and a filter screen 112 is provided inside the horizontally placed cylindrical body 111.

[0033] In some embodiments of this utility model, the diameters of the suction tube 120, the connecting tube 131, and the two dispensing tubes 132 are all smaller than the diameter of the horizontally placed cylinder 111.

[0034] In some embodiments of this utility model, the diameters of the suction pipe 120, the connecting pipe 131, and the two distributing pipes 132 are all smaller than the diameter of the horizontal cylinder 111. As the liquid refrigerant passes through the suction pipe 120, the liquid reservoir body 110, and the outlet pipe 130 in sequence, it forms a variable cross-section that changes from small to large and then back to small. This can effectively buffer the flow pulsation of the liquid refrigerant, effectively reduce vibration and suction noise, and effectively reduce the void effect caused by the vertical liquid reservoir.

[0035] In some embodiments of this utility model, a slow-flow tube 140 is provided at the outlet end of each of the two liquid distribution tubes 132.

[0036] In some embodiments of the present invention described above, a flow-retardant tube 140 is provided at the outlet end of the liquid distribution tube 132. The flow-retardant tube 140 increases the flow resistance of the liquid refrigerant, thereby buffering the liquid refrigerant, increasing the flow path length of the liquid refrigerant, and improving the buffering effect.

[0038] In some of the embodiments of this utility model described above, the flow-slowing tube 140 is an S-shaped tube. The S-shaped tube can better increase the flow resistance of the liquid refrigerant, play a buffering role for the liquid refrigerant, increase the flow path length of the liquid refrigerant, and improve the buffering effect.

The horizontal sections 141 are horizontally arranged, and the diameter of the horizontal sections 141 gradually decreases from the slow-flow pipe 140 towards both ends. Before and after the liquid refrigerant enters the slow-flow pipe 140, a variable cross-section flow path can be formed in the horizontal sections 141 of the gradual structure, further improving the buffering effect.

[0041] In some embodiments of this utility model, the end diameter of the horizontal section 141 is the same as the diameter of the liquid distribution tube 132.
