In addition, irregular adhesion will also cause the dynamic balance of the rotor to deteriorate and the vibration to exceed the standard. Every time it runs for a period of time (2 to 3 months), it will be forced to stop production for maintenance, which seriously affects production. Summary of the invention

[0027] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0028] See also Figure 1-4 As shown, according to an embodiment of the present application, a compressor impeller water flushing system is provided, comprising: a water tank 1, a water supply assembly 2, a water outlet pipeline 3, a connecting pipeline 4, a driving pump 5 and a branch pipe 6;

[0029] The water supply assembly 2 is connected to the water tank 1 and is used to fill water into the water tank 1. The first end of the water outlet pipe 3 is connected to the bottom of the water tank 1, and the second end of the water outlet pipe 3 is connected to the connecting pipe 4. The water outlet pipe 3 is provided with a driving pump 5. The first end of the branch pipe 6 is provided on the connecting pipe 4, and the second end of the branch pipe 6 is connected to the compressor intake pipe.

[0030] Specifically, the water supply component 2 is used to supply external water source into the water tank 1, and keep water stored in the water tank 1. When the compressor impeller needs to be cleaned, starting the drive pump 5 can supply the water stored in the water tank 1 into the connecting pipe 4, and supply it to each compressor intake pipe through multiple branch pipes 6 to form high-pressure atomized water, which can peel off the attachments on the compressor impeller, so that the dynamic balance of the rotor is not destroyed, the vibration value of the unit is stable, and it is close to the original design data of the unit, extending the service life of the compressor, and reducing maintenance costs, thereby ensuring the stable performance of large compressors and extending their safe operation cycle.

[0031] The driving pump 5 includes a driving motor and a centrifugal water pump, which are combined together through a mounting base and are used to pump water from the water tank 1 into the connecting pipe 4 during flushing.

[0032] The water supply assembly 2 includes: a water supply pipe 21, a water injection valve 22 and a water supply pipe 23;

[0033] The first end of the water supply pipe 21 is located inside the water tank 1, the water filling valve 22 is arranged inside the water tank 1 and connected to the first end of the water supply pipe 21, the second end of the water supply pipe 21 is connected to the top of the water tank 1, and the water supply pipe 23 is arranged on the water supply pipe 21, and the water supply pipe 23 is connected to an external water source.

[0034] The water injection valve 22 is an automatic float valve.

[0035] Specifically, the external water source is connected to the water supply pipe 21 through the water supply pipe 23, and the water filling valve 22 is connected to the first end of the water supply pipe 21 located inside the water tank 1. The water filling valve 22 is an automatic float valve, which will automatically open when the liquid level in the water tank 1 drops, and can automatically fill water into the water tank 1 until the water filling valve 22 automatically closes after the designed volume is reached. There is no need to manually observe the water level in the water tank 1 or manually fill the water into the water tank. The water filling is more automated and convenient.

[0036] A filter 7 is provided between the first end of the water outlet pipeline 3 and the driving pump 5 .

[0037] Specifically, by installing the filter 7 on the water outlet pipe 3 between the water outlet of the water tank 1 and the water inlet of the driving pump 5, impurities in the water discharged from the water tank 1 can be filtered to prevent the impurities from causing wear to the driving pump 5 and causing its performance to deteriorate. It also prevents impurities from being fed into the compressor intake pipe through the connecting pipe 4 and the branch pipe 6, causing damage to the impeller during cleaning, thereby affecting the subsequent normal use of the compressor.

[0038] Among them, the filter 7 is a pre-pump filter, which can be easily disassembled after use to clean the internal impurities, thereby ensuring the efficiency of filtering impurities in the water.

[0039] A vent pipe 8 is provided between the first end of the water outlet pipeline 3 and the filter 7 .

[0040] Specifically, by setting the drain pipe 8, the water inside the water tank 1 can be discharged according to demand, which is convenient for maintenance of the water tank 1 and the components installed inside the water tank 1, and the operation is convenient.

[0041] A regulating pipe 9 is provided between the water outlet pipeline 3 and the water tank 1 , a regulating valve 10 is provided on the regulating pipe 9 , and the regulating pipe 9 is located between the driving pump 5 and the connecting pipeline 4 .

[0042] Specifically, the regulating pipe 9 is installed between the connecting pipe 4 and the water tank 1, and a regulating valve 10 is installed on the regulating pipe 9. Through the setting of the regulating pipe 9 and the regulating valve 10, the water volume output by the driving pump 5 and the pressure of the stable water supply port can be adjusted to ensure the designed output value.

[0043] A liquid level transmitter 11 is disposed on the top of the water tank 1 , and a liquid level meter 12 is disposed on one side of the water tank 1 .

[0044] Specifically, the liquid level transmitter 11 is used to monitor the liquid level of the water in the water tank 1 in real time. The low alarm liquid level is set by the liquid level transmitter 11. When the liquid level transmitter 11 detects that the liquid level in the water tank 1 is lower than the low alarm liquid level, it will alarm and warn the staff to remind them to check the liquid level inside the water tank 1 and troubleshoot the failure of the water injection valve 22 to automatically replenish water into the water tank 1, thereby improving the stability of use and further ensuring that the water level in the water tank 1 meets the use requirements. The liquid level meter 12 is installed on one side of the water tank 1, and is mainly used for the staff to observe the liquid level in the water tank 1 on site, so that the liquid level in the water tank 1 can be visually seen.

[0045] The top of the water tank 1 is provided with a drain port 13 and a standby port 14 .

[0046] Specifically, the vent port 13 and the spare port 14 are respectively installed at the top of the water tank 1. The vent port 13 is mainly used to connect to the atmosphere to prevent negative pressure from being generated inside the water tank 1 during use, which affects the subsequent efficiency of extracting water from the water tank 1; the spare port 14 is mainly used for the subsequent temporary addition of parts and equipment to meet subsequent improvement needs.

[0047] A maintenance hole is opened on one side of the water tank 1 , the sealing head 15 is arranged on the maintenance hole, and the first end of the water supply pipe 21 passes through the sealing head 15 and is arranged inside the water tank 1 .

[0048] Specifically, the head 15 can be detachably mounted on the inspection hole of the water tank 1. When the interior of the water tank 1 needs to be inspected, the head 15 can be removed, and the staff can enter the interior of the water tank 1 through the inspection hole to inspect the internal components of the water tank 1.

[0049] It also includes a base 16 , which is arranged at the bottom of the water tank 1 .

[0050] Specifically, the base 16 can support and prevent the water tank 1, thereby improving the stability of the water tank 1 and improving the safety of use.

[0051] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application shall be included in the protection scope of the present application. The above are only preferred implementations of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and variations can be made without departing from the technical principles of the present application, and these improvements and variations should also be regarded as the protection scope of the present application.
