Description

Technical Field

It mainly consists of a test bench and a water tank.

[0003] The test bench has an external high-pressure pipeline and an externally equipped water tank, and the water tank is connected to the pump with a hose.

[0004] The test piece is placed on the ground of the external workshop, and additional measures need to be taken to position and fasten it, and the pipeline is connected with a hose. The processes of clamping, pressing, and pipeline connection are relatively cumbersome, time-consuming, and low in efficiency. The end covers at both ends of the motor housing are replaced with test end covers, and bolts need to be used for manual fastening, which is time-consuming and laborious.

[0005] Generally, a computer, a monitor, and a keyboard are equipped on the test bench. During the pressure testing process, data is transmitted to the computer through a controller or PLC and other detection components, and real-time recording and monitoring of data can be carried out, with timely error reporting and reminders, observing the pressure curve, and printing reports.

[0006] In addition, several pressure gauges and control knobs are equipped on the test bench to control the system pressure, system start and stop, remote / local, pressure testing and pressure holding, manual / automatic, etc., and to control the pressure testing time.

[0007] During the water filling and air exhausting links, manual confirmation is required, and deviations are likely to occur during the operation process.

[0008] There are no safety protection measures around the test workpiece, and high-pressure water leakage may cause personal injury.

Outside the existing test bench, a large hydraulic pressing device is used to press the workpiece to be tested from above, and cylinders are also used to press it from both sides. However, its structure is complex and the price is relatively high. Content of the Utility Model

This test device saves the pressure test data to an excel table for convenient future reference. In addition, operations such as manual data recording and report generation can also be carried out.

[0051] The distribution board 5 is of an openable type and is used for installing internal equipment and wiring.

[0052] The instrument panel 7 is arranged above the operating table and is placed obliquely.

[0057] See again Figure 1 and 2 , casters 19 and universal wheels 28 are installed under the frame 1 to support the overall test bench and facilitate shifting. Both the casters 19 and the universal wheels 28 are equipped with braking devices, which are braked after the shifting is completed to prevent the test bench from moving during the test.

[0058] The frame 1 supports the base 31 of the test bench. The base 31 is provided with a plurality of T-shaped grooves at suitable positions, and the adjusted position of the inclined support seat 29 is fixed by T-shaped bolts 30.

[0059] As Figure 2 and 3As shown, the part of the upper part of the frame lower than the base 31 is enclosed, and a water tank for storing the leaked liquid during the pressure test is formed by the bottom plate and the four walls to prevent the leaked liquid from flowing out during the pressure test.

[0060] Refer to again Figure 2 , two groups of pressing supports 20, pressing cylinders 21 and pressing blocks 22 are symmetrically arranged relative to the symmetry axis of the base 31 in a direction perpendicular to the T-shaped groove.

[0063] The oil cylinder valve block 25 is installed at the safety baffle which is a partition between the test bench and the control console area. It is equipped with an electromagnetic directional valve for controlling the pressing cylinder 21 and the clamping cylinder 39. The high-pressure hydraulic oil is provided by another hydraulic station. The control circuit of the electromagnetic directional valve is connected to the controller for unified control.

[0064] The high-pressure water pipeline at the pump outlet is connected to the pipe connection seat 26, and through Figure 3 the stop valve 34 and the quick-connect joint 35 in, the connection hose 36 is used to connect to the water filling and pressure test joint 37 to test the motor housing.

[0065] Combined with again Figure 3 , the pipe connection seat 26 is located at the safety baffle 23 which is a partition between the operation table and the test bench area. It is fixed to a beam of the frame 1 with bolts. There are connection holes on its back for connecting to the high-pressure pipeline at the pump outlet, and multiple high-pressure pipeline outlets are provided below, and the specific number is determined according to the number of pressure test product interfaces. Each pipeline is marked with the pipeline interface specification. The stop valve 34 and the quick-connect joint 35 are connected to the pipe connection seat 26. A stop valve 34 is provided at each high-pressure pipeline outlet for controlling the on-off of this high-pressure pipeline. A quick-connect joint 35 is equipped at each high-pressure pipeline outlet and is quickly connected to the water filling and pressure test joint 37 through the connection hose 36.

[0067] Two clamping supports 40 are longitudinally supported on the frame 1 along the longitudinal direction of the base 31, that is, along the longitudinal direction of the motor housing. More specifically, they are supported on the bottom plate of the water tank. Each clamping support 40 is equipped with a clamping oil cylinder 39. The two groups of clamping supports 40 and clamping oil cylinders 39 are symmetrically arranged with each other and are movably connected to the compression flange 32. There is a pipeline on the left compression flange and an air release plug 33 is equipped to release the internal air when filling with water. There is a water filling and pressure testing joint 37 on the right compression flange. After filling with water, a hose can be connected to conduct a pressure test. A liquid level transmitter 38 is equipped on the water filling and pressure testing pipeline to monitor the water filling situation.

[0068] Outside the frame, a drain port 41 is provided at the anchor of the water tank to release the leaked liquid. By opening and closing the ball valve on the drain port, the leaked liquid in the water tank can be cleaned.

[0069] For the motor housing of B3 type and other base connection types, it can be directly pressed onto the base 31 with a pressing plate. The installation dimensions of the motor housings of these base connection types are different. Therefore, the installation dimensions of the feet of these motor housings may not be the position of the T-shaped groove of the base 31. When using a pressing plate, the installation dimensions of these motor housings do not need to be considered. When the feet of the motor housing cannot be directly fixed with T-shaped bolts and T-shaped grooves, one end of the pressing plate can be freely fitted with the T-shaped groove and T-shaped bolts for fixation, so that the other end of the pressing plate can press the feet of these motor housings through such fixation. For other types of motor housings, the Figure 2 and Figure 3 shown positioning and pressing method can be adopted.

[0070] The utility model can make the pressure test process safe and reliable, with advanced technology and reasonable structural design. The installation and fixation of the motor housing are more convenient, and automatic pressing can be realized without manual operation. Equipped with a control device, the output pressure and time can be easily adjusted and controlled arbitrarily. The error rate of the connecting pipeline is reduced, and the working efficiency of the pressure test is effectively improved. Equipped with automatic data acquisition components to observe the pressure curve and print reports. The pressure test data is saved to a set form for convenient future reference.
