Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of protective tooling, and in particular to a pressure testing protective tooling. Background Technology
[0002] Before a water pump leaves the factory, the pump casing needs to undergo a pressure test to ensure that it meets quality standards.
[0003] In the prior art, patent document with publication number CN202122182869.0 discloses a pressure testing device for a high-pressure pump body, including: a high-pressure pump body, a discharge pipe connected to one side of the high-pressure pump body, a pressure testing chamber connected to the surface of the discharge pipe, two concave plates arranged inside the pressure testing chamber, and the two concave plates located on both sides of the discharge pipe, and a positioning mechanism arranged on the top of the two concave plates.
[0004] During use, it was found that the above-mentioned device lacked safety protection functions. As a result, when the pump body was subjected to pressure testing, unqualified pump bodies would scatter fragments or the pump body would rupture, causing the test medium to spray out, which would affect the safety of the surrounding personnel. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides a pressure testing and protective fixture.
[0006] This utility model discloses a pressure testing protective fixture, comprising a workbench, a tank, support rods, a support platform, a filter screen, and a wiring port. The workbench has a tank at its top, and multiple sets of support rods are installed at its bottom, with the tops of each set of support rods connected to the bottom of the support platform. A filter screen and a wiring port are provided on the support platform. The fixture also includes a protective component and a drainage component. The protective component and the drainage component are both located on the workbench, with the inlet of the drainage component communicating with the tank. The device to be tested is placed on the support platform, and the pressure pipe passes through the wiring port to connect with the pump body. The protective component is then installed over the support platform, forming a sealed space. If the pump body bursts and fragments fly, the fragments are confined by the sealed space, preventing injury to nearby personnel. If the pump body ruptures and the test medium leaks out, the sealed space prevents the leaked test medium from being ejected, and the test medium is collected through the filter screen and the tank.
[0007] Preferably, the protective components include columns, beams, motors, lead screws, top plates, threaded connecting blocks, guide plates, enclosures, and limiting blocks. A column is mounted on the top of the workbench, with the top of each column connected to the bottom of the beam. A motor is mounted on the beam, and a lead screw is mounted on the motor's output end. A threaded connecting block is mounted on the top plate, and the lead screw is threadedly connected to the threaded connecting block. A limiting block is mounted at the bottom of the lead screw. An enclosure is mounted at the bottom of the top plate, and guide plates are symmetrically arranged on the outer wall of the top plate, slidingly connected to the column. The pump body is placed on the support platform, and after the stamping pipe passes through the wiring port and connects to the pump body, the motor is started, causing the lead screw to rotate. Because the lead screw is threadedly connected to the threaded connecting block, the lead screw, in conjunction with the guide plates and columns, causes the top plate and enclosure to descend. The bottom of the enclosure contacts the top of the support platform, and the top plate, enclosure, and support platform form a sealed space, providing safety protection for surrounding personnel.
[0008] Preferably, the drainage assembly includes a drainage pipe and a drainage valve. The drainage pipe is installed on the workbench, and the inlet end of the drainage pipe is connected to the tank. The drainage valve is installed on the drainage pipe. The tank collects the outflowing test medium. The drainage valve is opened so that the test medium can be reused by flowing out through the drainage pipe.
[0009] Preferably, it also includes reinforcing bars, and multiple sets of reinforcing bars are evenly spaced on the outer wall of the fence; the multiple sets of reinforcing bars work together to improve the stability of the fence.
[0010] Preferably, the enclosure also includes insert rods and slots. The bottom end of the enclosure is provided with multiple sets of insert rods, and the support is provided with multiple sets of slots. The slots are adapted to the insert rods. When the bottom end of the enclosure contacts the top end of the support, the multiple sets of insert rods are inserted into a set of slots respectively, thereby improving the sealing firmness.
[0011] Preferably, it also includes an observation window, with an observation opening provided on the enclosure and an observation window installed on the observation opening; staff can observe the pressure testing of the pump in the enclosed space through the observation window, improving convenience.
[0012] Preferably, the device also includes adjustable feet, with a set of adjustable feet provided at each of the four corners of the bottom of the workbench; the four sets of adjustable feet work together to provide stable support for the device and improve its stability.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the body to be tested is placed on the support, the stamping pipe passes through the wiring port and connects to the pump body, and then the protective component is installed on the top of the support. The protective component and the support form a closed space. When the pump body bursts and fragments fly, the fragments are confined by the closed space to prevent the fragments from injuring the surrounding personnel. When the pump body breaks and the test medium flows out, the closed space prevents the outflowing test medium from being sprayed out, and the test medium is collected through the filter screen and the tank.
