Description

Technical Field

[0001] This utility model relates to a coil pressure loss testing system, belonging to the field of pressure loss testing technology. Background Technology

[0002] As a heat exchange and heat dissipation device within a closed-circuit cooling tower, the application of closed-circuit cooling towers is becoming increasingly widespread due to rising customer demands for water quality, leading to a gradual increase in the demand for coils. As a key component for heat and mass transfer in a closed-circuit cooling tower, its heat dissipation capacity directly affects the overall operating performance of the tower. To balance pressure loss and cooling effect, appropriate coil specifications need to be selected based on the customer's water volume requirements, and testing must be conducted in advance to ensure performance. Current technology uses whole-tower testing. If pressure testing is to be performed on individual coils, different sized support frames need to be selected based on the coil specifications, wasting significant manpower and resources. Furthermore, pressure loss testing of coils of different specifications involves pipe replacement, and equipment switching during this process may lead to test deviations, making accurate data comparison impossible.

Detailed Implementation

[0016] The following is in conjunction with the appendix Figure 1-2 Further explanation of this utility model:

[0017] A coil pressure loss testing system includes a support frame 9 compatible with coils 8 of different sizes. The inlet and outlet ends of the coil 8 are detachably connected to an inlet pipe 3.2 and an outlet pipe 3.1, respectively. The outlet pipe 3.1 is sequentially equipped with an air vent valve a6 and a pressure gauge a5 along the outlet direction. An ultrasonic flow meter is connected to the end of the outlet pipe 3.1. The inlet pipe 3.2 is sequentially equipped with a delivery pump 1, a pressure gauge b12, and an air vent valve b10 along the liquid flow direction. The air vent valves a6 and b10... All 0 are automatic air vent valves, which realize automatic air venting of the pipeline, thereby making the pressure gauge test results more accurate. The inlet ends of air vent valves a6 and b10 are respectively equipped with ball valves a7 and b11. The medium enters the air vent valve after passing through the ball valve. The ball valve is used to control the flow rate of the medium through the air vent valve. The front end of the liquid inlet pipeline 3.2 is connected to gate valve 2. Gate valve 2 is connected to the ultrasonic flow meter through a metal bellows with adjustable length. By extending and retracting the metal bellows, it can adapt to the installation of coils 8 of different sizes.

[0018] The support frame 9 includes support columns 9.2 fixed to both ends of the connecting beam 9.1. The bottom of the support columns 9.2 is fixed to the base, and support arms 9.3 are rotatably connected to the support columns 9.2. The support arms 9.3 are set at the same height as the support arms 9.3 at both ends of the connecting beam 9.1. The support column 9.2 has five parallel and equal-length support arms 9.3. The support arms 9.3 are rotatably connected to the support column 9.2 through rotating bushings, and the support column 9.2 has a lower limit block to prevent the rotating bushings from moving downwards. The five support arms 9.3 form a five-layer support structure on the support column 9.2, which can realize the vertical placement and testing of five sets of coils. The support arms 9.3 can be rotated according to the size of the coils, so that the support arms 9.3 are in the optimal support position for the coils 8, avoiding the dent in the middle of the coils due to gravity when placed, and thus avoiding inaccurate measurement results caused by the dent. During measurement, read the values ​​of pressure gauge b12 on the inlet pipe 3.2 and pressure gauge a5 on the outlet pipe 3.1, and calculate the pressure loss inside the pipe.

[0019] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
