Description

Technical Field

[0001] This utility model relates to the field of pressure testing pump technology, and in particular to an electric water pipe pressure testing pump. Background Technology

[0002] Pressure testing pumps are known to be specialized equipment for hydrostatic testing of various pressure vessels, pipelines, valves, boilers, cylinders, fire-fighting equipment, etc., and for obtaining high-pressure liquids in laboratories. Their main function is to detect and test the working pressure of pipelines, valves, fire-fighting equipment, etc., to ensure they can withstand certain pressures and meet relevant safety standards. Electric pressure testing pumps come in various structures, such as a reciprocating plunger pump where a motor drives a plunger, which in turn moves a slider to inject water into the object being tested, gradually increasing the pressure. This type of pump consists of a pump body, switch, pressure gauge, water tank, and motor. While there is also a vertical high-flow electric pressure testing pump disclosed in Chinese utility model patent CN221703907U, such pumps are large, increasing overall weight and making them inconvenient for users to carry and move, and also increasing manufacturing costs. Therefore, improvements are necessary to address the shortcomings of existing technologies. Utility Model Content

[0036] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit its scope. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the present utility model.

[0037] Example 1: See Figure 1 , Figure 2 , Figure 8 and Figure 9 An electric water pipe pressure testing pump includes a base plate 1 and a pressure testing pump 2 mounted on the base plate 1. The pressure testing pump 2 is equipped with a driver 3 for driving the pressure testing pump 2, a water inlet pipe 4 is mounted on the pressure testing pump 2, and a water outlet fitting 5 is provided on the pressure testing pump 2. The water outlet fitting 5 is equipped with a pressure gauge 6 and a drain valve 7, and the water outlet fitting 5 is used to connect to external equipment that needs to be tested. In use, as long as the driver 3 is started, the pressure testing pump 2 can flow through the water inlet pipe 4 to the water outlet fitting 5. Since the water outlet fitting 5 is used to connect to external equipment that needs to be tested, pressure testing can be performed on the testing equipment connected to the water outlet fitting 5.

[0038] Example 2: This can be explained based on Example 1, such as... Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 10 and Figure 11 As shown, it also includes a water tank 8, which has a chamber 81 for storing water. A base plate 1 is provided on the upper surface of the water tank 8, and a notch 82 is formed between the base plate 1 and the water tank 8. This arrangement allows users to easily observe the water level in the chamber 81 and facilitates water intake, thus better meeting user needs. In use, once the driver 3 is started, the pressure testing pump 2 can pump water from the chamber 81 through the water inlet pipe 4 to the outlet pipe fitting 5. Since the outlet pipe fitting 5 is used to connect to external testing equipment, pressure testing can be performed on the equipment connected to the outlet pipe fitting 5.

[0039] Example 3: This can be described based on Example 1 or Example 2, such as... Figures 1 to 11As shown, the pressure testing pump 2 includes a housing 21 mounted on a base plate 1. A water inlet pipe 4 is mounted on the lower end face of the housing 21. A cylinder 22 is mounted inside the housing 21. A connecting rod 23 is mounted inside the cylinder 22. A piston 25 is mounted on one end of the connecting rod 23 inside the cylinder 22. An eccentric shaft 24 is mounted on the other end of the connecting rod 23. The eccentric shaft 24 is connected to a driver 3. A water outlet pipe 5 is mounted on the cylinder 22. This facilitates the driver 3 to drive the eccentric shaft 24, which in turn drives the connecting rod 23 to move. The connecting rod 23 will drive the piston to move in the cylinder 22, which will cause the water inlet pipe 4 to introduce water into the water outlet pipe 5.

[0040] like Figures 1 to 7 As shown, the driver 3 includes a housing 30 mounted on a casing 21. An eccentric shaft 24 extends into the housing 30. A first bearing 31 and a first gear 32 are mounted on the eccentric shaft 24 inside the housing 30. The first gear 32 meshes with a second gear 33. At least one second bearing 34 is mounted on the second gear 33. A rotating shaft 35 is mounted on the second bearing 34. The rotating shaft 35 is externally connected to an electric drill, facilitating startup via an external device. In this embodiment, two second bearings 34 are used, a reasonable and easy-to-implement arrangement. Or, as... Figures 8 to 11 As shown, the driver 3 includes a housing 36 mounted on a casing 21. A control switch 37 and a power supply 38 are mounted on the housing 36. A motor 39 is housed inside the housing 36, connected to the control switch 37, which in turn connects to the power supply 38. The output shaft of the motor 39 is connected to an eccentric shaft 24. This allows the pressure testing pump 2 to be started and stopped by controlling the motor 39, thus better meeting usage requirements. Furthermore, the power supply 38 uses a battery, which is convenient to implement. This utility model driver 3 comes in various types, offering a wide range of choices.

[0041] Example 4: This can be described based on Example 1, Example 2, or Example 3, such as... Figures 1 to 11 As shown, the water outlet fitting 5 includes a water delivery pipe 51 mounted on the pressure testing pump 2, a connecting pipe 52 mounted on the water delivery pipe 51, a water pipe connector 53 mounted on the outer end face of the connecting pipe 52, a pressure gauge 6 and a drain valve 7 mounted on the connecting pipe 52. This arrangement is reasonable and can realize water delivery and pressure measurement. Further explanation: the drain valve 7 includes a spring 71 mounted inside the connecting pipe 52, a movable plug 72 for opening and closing the water delivery pipe 51 mounted inside the connecting pipe 52, and a valve body 73 mounted on the connecting pipe 52. This arrangement is reasonable and facilitates the opening and closing function.

[0042] All standard parts used in this application can be purchased from the market. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and drain valves that are mature in the existing technology. The internal components of the power supply and motor adopt conventional models in the existing technology, and their internal structure belongs to the existing technology structure. Workers can complete the normal operation of them according to the existing technical manual. In addition, the circuit connection adopts conventional connection methods in the existing technology, and will not be described in detail here.

[0043] It should be noted that although the above embodiments have been described herein, this does not limit the scope of patent protection for this utility model. Therefore, any changes and modifications made to the embodiments described herein based on the innovative concept of this utility model, or equivalent structural or procedural transformations made using the content of this utility model's specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields, are all included within the scope of protection of this utility model patent.
