Description

Technical Field

[0001] This utility model relates to the field of fracturing pump testing technology, specifically fracturing pump testing fixtures. Background Technology

[0002] Air tightness testing of fracturing pumps is a key step in ensuring their sealing reliability under high pressure conditions. It mainly targets the hydraulic end (such as plunger valve box seals) and high-pressure pipeline system. In the existing technology, fracturing pump testing fixtures are used to test air tightness by immersing the pump in water. However, after the test, there is residual water on the pump, which makes it inconvenient to dry the pump, making the drying process less than ideal.

[0003] For example, patent publication number CN215672160U specifically describes a pressure testing fixture for a fracturing pump valve box. The fracturing pump valve box is located inside a testing water tank and below the liquid level. A buffer component is located inside the testing water tank to support the fracturing pump valve box. A pressurizing assembly is located outside the testing water tank and communicates with the interior of the fracturing pump valve box. The buffer component includes a buffer plate and a connecting assembly hinged to opposite sides of the buffer plate. The connecting assembly includes at least two connecting members. One end of the cylinder is hinged to the inner wall of the testing water tank, and one end of the connecting rod is connected to a limiting element inside the cylinder. The block is fixedly connected, and the first spring is sleeved on the connecting rod inside the cylinder. The other end of the connecting rod extends to the outside of the cylinder and is hinged to one side of the buffer plate. This solves the problem that traditional testing water tanks do not have buffer components, and when the fracturing pump valve box is moved to the testing water tank by a gantry crane, the falling speed is too fast and can easily damage the fracturing pump valve box. There is also the problem that this fracturing pump testing fixture performs air tightness testing by immersing the pump in water. However, after the test, there is residual water on the pump, which is inconvenient to dry the pump, making the drying convenience not ideal. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a fracturing pump testing fixture, which solves the problem that while the fracturing pump testing fixture performs airtightness testing by immersing the pump in water, residual moisture remains on the pump after the test, making it inconvenient to dry the pump and resulting in less than ideal drying convenience.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a fracturing pump testing fixture, including a water tank, a drying box on one side of the water tank, a drying mechanism on the drying box, and a buffer mechanism inside the water tank;

[0006] The air-drying mechanism includes a support base, a rotating base rotatably connected to the outside of the support base, two branch pipes fixedly connected to the bottom of the rotating base, a three-way pipe fixedly connected to the bottom of the two branch pipes, a driven gear fixedly connected to the three-way pipe, a driving gear provided on one side of the driven gear, a drive motor fixedly connected to the end of the driving gear, two guide seats fixedly connected to the top of the rotating base, an adjusting screw rotatably connected inside each of the two guide seats, a guide slider threadedly connected to the adjusting screw, a connecting plate fixedly connected to the top of the guide slider, an air-drying rack fixedly connected to one end of the connecting plate, and multiple air outlets opened on the air-drying rack.

[0007] Preferably, the support base is fixedly installed on the drying oven, and the rotating base is rotatably connected to the inner wall of the drying oven through a bearing, so that the rotating base can rotate stably.

[0009] Preferably, the drive motor is fixedly installed inside the drying oven via a flange, and the drive motor is provided with a waterproof shell, which can protect the drive motor and improve the protection effect of the drive motor.

[0010] Preferably, the two guide seats are symmetrically arranged on the rotating seat, and the guide seats are slidably connected to the guide slider, so that the guide slider can guide the movement of the guide seats.

[0011] Preferably, the two drying racks are symmetrically arranged on the two connecting plates, and the bottom ends of the two drying racks are connected to the branch pipe through flexible hoses, so that flowing air can enter the drying racks through the branch pipes and flexible hoses.

[0012] Preferably, the buffer mechanism includes a support plate with multiple water-permeable holes, and multiple telescopic rods are fixedly connected to the bottom end of the support plate. Buffer springs are sleeved on the multiple telescopic rods to provide a buffering effect.

[0013] This utility model provides a testing fixture for fracturing pumps. Compared with the prior art, it has the following advantages:

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-3 This utility model provides a technical solution: a fracturing pump testing fixture, including a water tank 1, on which the fracturing pump is hoisted. A pump is located on one side of the water tank 1, which can be connected to the fracturing pump to inflate it and observe whether air bubbles are generated, thus enabling airtightness testing. A drying chamber 3 is located on one side of the water tank 1, with a sloped bottom surface to guide water. A drying mechanism 2 is located on the drying chamber 3, and a buffer mechanism 4 is located inside the water tank 1. The tested fracturing pump can be moved into the drying chamber 3, and the moisture on the pump can be dried using the drying mechanism 2, facilitating drying and improving drying convenience.

[0023] The air-drying mechanism 2 includes a support base 201, with a rotating seat 202 rotatably connected to the outside of the support base 201. The support base 201 is fixedly installed on the drying chamber 3, and the rotating seat 202 is rotatably connected to the inner wall of the drying chamber 3 via bearings, allowing the rotating seat 202 to rotate stably. Two branch pipes 203 are fixedly connected to the bottom end of the rotating seat 202, and a three-way pipe 204 is fixedly connected to the bottom end of the two branch pipes 203. The bottom of the three-way pipe 204 is connected to the air outlet of the blower via a rotary joint, allowing flowing air to pass through the three-way pipe 204 while it is rotating, thereby enabling the fracturing pump to be air-dried. A driven gear 205 is fixedly connected to the three-way pipe 204. A driving gear 206 is provided on one side of the driven gear 205. A drive motor 207 is fixedly connected to the end of the driving gear 206. The driving gear 206 meshes with the driven gear 205. The output shaft of the drive motor 207 is connected to the three-way pipe 204 through the driving gear 206 and the driven gear 205, so that the drive motor 207 can drive the three-way pipe 204 to rotate. The drive motor 207 is fixedly installed inside the drying oven 3 through a flange. The drive motor 207 is provided with a waterproof shell, so that the waterproof shell can be used to protect the drive motor. The drive motor 207 is protected to improve its protection effect. Two guide seats 208 are fixedly connected to the top of the rotating base 202. Each guide seat 208 has an adjusting screw 209 rotatably connected inside. The end of the adjusting screw 209 has an internal hexagonal groove, making it easy to rotate with a hex wrench. A guide slider 210 is threaded onto the adjusting screw 209. The two guide seats 208 are symmetrically arranged on the rotating base 202, and the guide seats 208 are slidably connected to the guide slider 210, allowing the guide slider 210 to move the guide seats 208. The guide slider 210 is fixedly connected to a connecting plate 211 at its top end. One end of the connecting plate 211 is fixedly connected to a drying rack 212. Two drying racks 212 are symmetrically arranged on the two connecting plates 211. The bottom ends of the two drying racks 212 are connected to the branch pipe 203 through a flexible hose, so that the flowing air can enter the drying rack 212 through the branch pipe 203 and the flexible hose, and the drying rack 212 can move within a certain range while maintaining a connected state. The drying rack 212 has multiple air outlets 213, which can be used to blow air to the fracturing pump.

[0024] Please see Figure 1 and Figure 4 The buffer mechanism 4 includes a support plate 401, on which multiple water-permeable holes 402 are provided to allow water to pass through. Multiple telescopic rods 403 are fixedly connected to the bottom end of the support plate 401, and buffer springs 404 are sleeved on the multiple telescopic rods 403. The telescopic rods 403 can guide the movement of the support plate 401, and the buffer springs 404 can buffer the pressure pump placed on the support plate 401.

[0025] During operation, the distance between the two drying racks 212 is adjusted according to the size of the fracturing pump. Rotating the adjusting screw 209 moves the guide slider 210, which in turn moves the connecting plate 211, which in turn moves the drying racks 212, shortening the distance between the two drying racks 212 and the fracturing pump. Then, the tested fracturing pump is hoisted onto the support base 201. The drive motor 207 drives the drive gear 206 to rotate, which in turn drives the driven gear 205 to rotate, which in turn drives the tee pipe 204 to rotate, which in turn drives the branch pipe 203 to rotate, which in turn drives the rotating seat 202 to rotate, which in turn drives the drying racks 212 to rotate. During this rotation, a blower introduces air into the drying racks 212 and discharges it through the air outlet 213, thoroughly drying the fracturing pump and improving the ease of drying.
