Description

Technical Field

[0001] This utility model relates to the field of testing technology for condensate recovery pumps, specifically to a dedicated testing device for condensate recovery pumps. Background Technology

[0002] The condensate recovery pump adopts a top-mounted structure, which reduces the number of connecting bolts on the valve body under high pressure and large diameter conditions, enhancing valve reliability and overcoming the influence of system weight on normal valve operation. Condensate recovery pumps are widely used in pipelines in coal chemical, petrochemical, rubber, papermaking, and pharmaceutical industries as devices for diverting, merging, or switching the flow direction of media.

[0003] Condensate recovery pumps require functional testing during use, but there is currently no dedicated testing equipment available. Utility Model Content

[0004] This invention provides a dedicated testing device for condensate recovery pumps, aiming to solve the problems in the prior art.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0006] A dedicated testing device for condensate recovery pumps includes a water supply pipeline, a drainage pipeline, and a driving air source. One end of the water supply pipeline is used to connect to one side of the condensate recovery pump to be tested, and one end of the drainage pipeline is used to connect to the other side of the condensate recovery pump to be tested. The driving air source is used to connect to the top of the condensate recovery pump to be tested.

[0007] The beneficial effects of this invention are as follows: During the detection process, liquid water enters the condensate recovery pump tank through the water supply pipeline. At this time, due to its own structural characteristics, the external drive air source end of the recovery pump is in a closed state, and the direct-to-atmosphere end is in an open state. As the water level inside the tank rises, the air inside the recovery pump is discharged through the direct-to-atmosphere end interface. When the water level inside the recovery pump rises to a certain water level line, it triggers the recovery pump's own mechanism to close the direct-to-atmosphere end interface, open the external drive air source end, and the drive air source quickly enters the recovery pump tank. The internal pressure of the tank rises, and the condensate inside the tank is discharged along the outlet side through the drain pipeline.

[0008] As the condensate in the recovery pump is discharged and the water level drops to a certain level, the recovery pump's own mechanism is triggered again, opening the direct connection to the atmosphere and closing the external drive air source, thereby realizing the circulation of water in and out of the recovery pump. The above device is used to detect the functional operation of the condensate recovery pump and prevent the outflow of malfunctioning products.

[0009] This utility model has a simple structure and reasonable design, which can quickly detect the function of the condensate recovery pump. The detection is convenient and efficient.

[0010] Based on the above technical solution, the present invention can be further improved as follows.

[0011] Furthermore, it also includes a water collection tank, with the other end of the water supply pipe and the other end of the drainage pipe respectively connected to the water collection tank.

[0012] The beneficial effect of adopting the above-mentioned further solution is that during the detection process, liquid water enters the condensate recovery pump tank from the collection tank through the water supply pipeline. At this time, due to its own structural characteristics, the external drive air source end of the recovery pump is in a closed state, and the direct-to-atmosphere end is in a closed state. As the water level inside the tank rises, the air inside the recovery pump is discharged through the direct-to-atmosphere end interface. When the water level inside the recovery pump rises to a certain level, it triggers the recovery pump's own mechanism to close the direct-to-atmosphere end interface, open the external drive air source end, and the drive air source quickly enters the recovery pump tank. The internal pressure of the tank rises, and the condensate inside the tank is discharged along the outlet side through the drain pipeline and recovered back to the collection tank.

[0013] Furthermore, the other end of the water supply pipe is connected to the bottom of the water collection tank, and the other end of the drainage pipe is connected to the top of the water collection tank.

[0017] Furthermore, a water supply metal hose section is connected to the water supply pipeline.

The functions of the water supply metal hose section are: firstly, reducing pipeline deformation and thermal stress: the metal hose can utilize its own elastic expansion joint function to reduce axial, angular, and lateral displacement of the pipeline caused by thermal deformation, industrial equipment deformation, etc., thereby improving the service life of the pipeline; secondly, flexible connection and buffering function: in the pipeline system, the metal hose can play the role of flexible connection, especially when the pipeline has axial or angular displacement requirements, it can play a good buffering role and protect the pipeline system from damage.

[0019] Furthermore, a water supply ball valve is also installed on the water supply pipeline, and the water supply ball valve is located between the water supply metal hose section and the other end of the water supply pipeline.

[0020] The advantages of adopting the above-mentioned further solution are that it has a simple structure, reasonable design, and uses a water supply ball valve to control the on / off of the water supply pipeline, making it easy to detect.

[0021] Furthermore, a water supply check valve is also installed on the water supply pipeline, and the water supply check valve is located between the water supply metal hose section and one end of the water supply pipeline.

[0022] The advantages of adopting the above-mentioned further solution are that it has a simple structure, reasonable design, and uses a water supply check valve to prevent liquid water in the water supply pipeline from flowing back.

[0023] Furthermore, a section of flexible metal drainage hose is connected to the drainage pipe.

[0035] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0036] Example 1

[0037] like Figure 1 As shown, this embodiment provides a dedicated testing device for condensate recovery pumps, including a water supply pipeline 1, a drainage pipeline 2, and a driving air source 3. One end of the water supply pipeline 1 is used to connect to one side of the condensate recovery pump 4 to be tested, and one end of the drainage pipeline 2 is used to connect to the other side of the condensate recovery pump 4 to be tested. The driving air source 3 is used to connect to the top of the condensate recovery pump 4 to be tested.

[0038] During the testing process, liquid water enters the condensate recovery pump tank through water supply pipeline 1. At this time, due to its own structural characteristics, the external drive air source end of the recovery pump is in a closed state, and the direct-to-atmosphere end is in a closed state. As the water level inside the tank rises, the air inside the recovery pump is discharged through the direct-to-atmosphere end interface. When the water level inside the recovery pump rises to a certain level, it triggers the recovery pump's own mechanism to close the direct-to-atmosphere end interface, open the external drive air source end, and the drive air source quickly enters the recovery pump tank. The internal pressure of the tank rises, and the condensate inside the tank is discharged through the drain pipeline along the outlet side.

[0039] As the condensate in the recovery pump is discharged and the water level drops to a certain level, the recovery pump's own mechanism is triggered again, opening the direct connection to the atmosphere and closing the external drive air source, thereby realizing the circulation of water in and out of the recovery pump. The above device is used to detect the functional operation of the condensate recovery pump and prevent the outflow of malfunctioning products.

[0040] This embodiment has a simple structure and reasonable design, which can quickly detect the function of the condensate recovery pump. The detection is convenient and efficient.

[0042] Based on Embodiment 1, this embodiment also includes a water collection tank 5, with the other end of the water supply pipe 1 and the other end of the drainage pipe 2 respectively connected to the water collection tank 5.

[0043] During the testing process, liquid water enters the condensate recovery pump tank from the collection tank 5 via the water supply pipe 1. At this time, due to its structural characteristics, the external drive air source of the recovery pump is closed, while the direct-to-atmosphere port is open. As the water level inside the tank rises, the air inside the recovery pump is discharged through the direct-to-atmosphere port. When the water level in the recovery pump rises to a certain level, it triggers the pump's own mechanism, closing the direct-to-atmosphere port, opening the external drive air source, and rapidly introducing drive air into the recovery pump tank. This increases the internal pressure, causing the condensate inside the tank to be discharged along the outlet side through the drain pipe and returned to the collection tank.

[0047] During testing, the aforementioned water collection tank 5 is positioned above the condensate recovery pump 4. This design allows the liquid water in the water collection tank 5 to flow downwards naturally due to gravity, without requiring additional power.

[0048] In addition, by utilizing the increased internal pressure of the condensate recovery pump tank, the condensate inside the tank is discharged along the outlet side through the drainage pipe and recovered into the water collection tank.
