Description

Technical Field

[0001] The utility model relates to the technical field of water pump bearing body production, in particular to a pressure testing device for a water pump bearing body. Background Art

[0002] The bearing body is the core part of the water pump. It not only supports the rotor components of the water pump to ensure its stability and reliability, but also fixes the position of the shaft and ensures the rotation accuracy. Its production quality directly affects the performance and operation of the water pump. From the blank to the finished product, the bearing body goes through multiple processes such as blanking, casting, turning, milling, drilling, and pressure testing. Among them, the pressure test in the last process is the key to checking whether the parts are qualified. If the bearing body leaks, it will affect the normal operation of the water pump and even cause more serious consequences. Therefore, how to quickly and efficiently complete the pressure test of the bearing body is the key to ensuring product quality.

[0003] When the pressure test machine is working, it will pressurize the bearing body and detect the pressure value through the pressure gauge. However, the existing pressure test machine can only perform pressure test on one bearing body at a time when working, which is very inefficient in the production process of large quantities of bearing bodies. Therefore, a pressure test device for a water pump bearing body is proposed. Utility Model Content

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] The utility model provides a technical solution: Figures 1 to 4 As shown, in this embodiment, a pressure testing device for a water pump bearing body includes a pressure testing machine 1, and a No. 1 connecting block 4 is fixedly connected to the upper end of the pressure testing machine 1. One end of the No. 1 connecting block 4 is provided with a main pipe interface 13, and the other end of the No. 1 connecting block 4 is provided with three branch pipe interfaces 14. A connecting water channel connecting the main pipe interface 13 and the three branch pipe interfaces 14 is opened in the No. 1 connecting block 4. The main pipe interface 13 is connected to the pressure testing machine 1 through a connecting main pipe 11, and the three branch pipe interfaces 14 are respectively connected to pressure detection components.

[0021] Among them, the pressure detection component is composed of a connecting branch pipe 10, a No. 2 connecting block 5, a pressure gauge 6 and a pressure measuring pipe 7. One ends of the three connecting branch pipes 10 are respectively connected to the branch pipe interface 14 through threaded cooperation, and the other ends of the three connecting branch pipes 10 are respectively fixedly connected to the No. 2 connecting block 5, which is fixedly installed on the top of the pressure testing machine 1. The upper end of the No. 2 connecting block 5 is provided with a pressure gauge 6, and the lower end of the pressure gauge 6 is installed in a threaded hole opened on the upper surface of the No. 2 connecting block 5 through threaded cooperation. The bottom of the threaded hole is connected to the interior of the No. 2 connecting block 5. A pipe joint 8 is provided at one end of the No. 2 connecting block 5 away from the connecting branch pipe 10, one end of the pressure measuring pipe 7 is connected to the pipe joint 8, and the other end of the pressure measuring pipe 7 is connected to the water pump bearing body.

[0022] A manual stop valve 9 is provided on the connecting branch pipe 10 , and the bottom of the manual stop valve 9 is fixedly connected to the pressure testing machine 1 through a mounting seat 12 .

[0023] Whether the pressure detection component is working can be controlled by the manual stop valve 9.

[0024] Among them, fixed vertical plates 2 are fixedly connected to both sides of the upper end of the pressure testing machine 1, and a handle 3 is arranged between the two fixed vertical plates 2. The handle 3 is a U-shaped structure, and the two ends of the handle 3 are rotatably connected to the side walls of the two fixed vertical plates 2 close to each other.

[0025] The handle 3 is provided to facilitate the user to take the device, thereby improving the convenience of the device.

[0026] The length of the two parallel plates of the handle 3 is greater than the length of the pump body on the pressure testing machine 1 .

[0027] Such an arrangement can prevent the pump body on the pressure testing machine 1 from affecting the movement of the handle 3 .

[0028] The utility model provides a pressure testing device for a water pump bearing body, and the specific working principle is as follows:

[0029] When in use, before the pressure test, one end of the pressure measuring pipe 7 is connected to the pipe joint 8, and the other end of the pressure measuring pipe 7 is installed on the water pump bearing body. Then, all the manual stop valves 9 are opened to start the pressure tester 1. The pressure tester 1 will inject water into the water pump bearing body to gradually increase its pressure. By observing the pressure value of the pressure gauge 6, it is judged whether the pressure test requirement is met. After the pressure value is reached, the pressure is maintained for a prescribed time to observe whether the water pump bearing body is leaking or sweating. If there is no such phenomenon, it means that the water pump bearing body has passed the pressure test. The pressure test device can be connected to three pressure detection components, and three identical water pump bearing bodies can be pressure tested at the same time, which can effectively improve the detection efficiency of the water pump bearing body, thereby improving its production efficiency.
