Description

Technical Field

[0001] This utility model relates to the field of vacuum pump testing, and more specifically, to a vacuum pump performance testing device. Background Technology

[0002] A vacuum pump is a device or equipment that uses mechanical, physical, chemical, or physicochemical methods to evacuate a container and create a vacuum. After manufacturing, existing vacuum pumps require performance testing, which is crucial to ensure they meet the needs of various applications. Pumping rate, also known as flow rate, is one such test component. It refers to the volume of gas removed by a vacuum pump per unit time under a given pressure. It measures how quickly a vacuum pump can achieve the required vacuum level at a specific pressure; a higher pumping rate indicates that the pump can reach the desired vacuum level in a shorter time.

[0003] Existing vacuum pump pumping speed performance testing devices require not only collecting pumping rate data but also simultaneously collecting multiple parameters such as pressure, temperature, and motor power. This necessitates operators simultaneously managing multiple data acquisition devices and ensuring data synchronization, increasing operational complexity. Solving these problems has become a pressing issue for those skilled in the art. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a vacuum pump performance testing device, which aims to solve the problem that the existing vacuum pump pumping speed performance testing devices are difficult to operate because they require the collection of multiple data parameters.

[0005] This utility model is implemented as follows:

[0006] This utility model provides a vacuum pump performance testing device, including a bracket, a tank is provided on the top of the bracket, a vacuum sensor is provided on the surface of the tank, a data display component is provided on the surface of the bracket, a bellows is provided above the bracket, and a ventilation component is provided on the outer wall of the bracket.

[0007] The data display component includes a placement panel and an electronic display vacuum gauge. The placement panel is fixedly connected to the top of the bracket, and the electronic display vacuum gauge is fixedly connected to the surface of the placement panel.

[0008] Preferably, the electronic display vacuum gauge is distributed on the surface of the placement panel, and the vacuum sensor on the surface of the tank is connected to the electronic display vacuum gauge via a data wire.

[0009] By adopting the above technical solution, multiple electronic display vacuum gauges can record different data, which facilitates subsequent data copying by operators.

[0010] Preferably, one end of the bellows is fixedly connected to the tank body, and the bottom of the tank body is provided with an air inlet connected to the input end of the vacuum pump to be tested.

[0011] By adopting the above technical solution, outside air can enter the interior of the tank through the bellows and can be connected to the input end of the vacuum pump under test through the air port, thereby measuring the pumping speed of the vacuum pump.

[0012] Preferably, the ventilation assembly includes a split pipe, a flow meter, and a vacuum valve. The split pipe is disposed above the support, the flow meter is fixedly connected to the bottom of the split pipe, and the vacuum valve is installed on the surface of the split pipe.

[0013] Preferably, the diverter pipe is fixedly connected to the end of the corrugated pipe away from the tank body, the surface of the flow meter is provided with a valve, the flow meters are distributed at the bottom of the diverter pipe, and the inner diameters of the multiple flow meters are different.

[0014] By adopting the above technical solution, airflow can enter the interior of the bellows through the diverter pipe, and the opening and closing of the flow meter can be controlled by the valve. Flow meters with different inner diameters can control the flow rate of air flowing into the bellows.

[0015] Preferably, the vacuum valves are distributed on the surface of the distribution pipe, the vacuum valves are connected to the distribution pipe, and different vacuum valves correspond to flow meters with different pipe diameters.

[0016] By adopting the above technical solution, the gas flowing into the distributor pipe can be detected by a vacuum valve, thus preventing the gas flow rate from exceeding the specifications.

[0017] The beneficial effects of this utility model are:

[0018] 1. During measurement, first close all valves and vacuum valves on the ventilation assembly, allowing the pump to run to its ultimate vacuum. This step can be visually observed using a vacuum gauge. Then, starting from the smallest range vacuum valve, sequentially open and close the flow meter valves corresponding to different range vacuum valves and record the data. The process steps are clear and easy for operators to understand and follow. No complicated operating skills or professional training are required, thus solving the problem of high operational difficulty caused by the need to collect multiple data parameters when using existing vacuum pump pumping speed performance testing devices.

[0019] 2. The connection design between the various components of the device is relatively simple. For example, the connection between the bellows and the tank, and between vacuum valves of different specifications and flow meters, can be completed through conventional pipe connection methods without complicated assembly processes. It can quickly assemble the various parts for testing. At the same time, the vacuum value is directly displayed on the electronic display vacuum gauge set on the surface of the panel, which is easy to read. When processing data, you only need to input the recorded values ​​into the table to generate the pumping speed curve. There is no need for complicated manual calculations or the use of professional and cumbersome data analysis software, which simplifies the operation difficulty of subsequent data processing.

[0028] The data display component 3 includes a placement panel 301 and an electronic display vacuum gauge 302. The placement panel 301 is fixedly connected to the top of the bracket 1, and the electronic display vacuum gauge 302 is fixedly connected to the surface of the placement panel 301. The electronic display vacuum gauges 302 are distributed on the surface of the placement panel 301. The vacuum sensor set on the surface of the tank 2 is connected to the electronic display vacuum gauge 302 through a data cable. Multiple electronic display vacuum gauges 302 can record different data, which is convenient for operators to copy the data later. The data information inside the tank 2 can be transmitted to the electronic display vacuum gauge 302 through the data cable and displayed through the electronic display vacuum gauge 302.

[0029] The ventilation assembly 5 includes a diversion pipe 501, a flow meter 502, and a vacuum valve 503. The diversion pipe 501 is positioned above the support 1 and is fixedly connected to the end of the bellows 4 furthest from the tank 2. Airflow can enter the interior of the bellows 4 through the diversion pipe 501. The flow meter 502 is fixedly connected to the bottom of the diversion pipe 501 and has a valve on its surface. The flow meters 502 are distributed at the bottom of the diversion pipe 501, and the inner diameters of the multiple flow meters 502 are different. The flow meter 502 is controlled by a valve to open and close. Flow meters 502 with different inner diameters can control the flow rate of air flowing into the bellows 4. Vacuum valves 503 are installed on the surface of the distributor pipe 501. Vacuum valves 503 are distributed on the surface of the distributor pipe 501 and are connected to the distributor pipe 501. Different vacuum valves 503 correspond to flow meters 502 with different pipe diameters. The gas flowing into the distributor pipe 501 can be detected by the vacuum valves 503 to prevent the gas flow rate from exceeding the specifications.

[0030] During measurement, first, all valves on the ventilation assembly 5 are closed, and the pump is run to the ultimate vacuum. This step can be visually observed through a vacuum gauge.

This allows for quick assembly of the various parts for testing. At the same time, the vacuum degree value is directly displayed on the electronic display vacuum gauge 302 set on the surface of the placement panel 301, which is easy to read. During data processing, the recorded values ​​only need to be entered into the table to generate the pumping speed curve.

The bellows 4 is connected to vacuum valves 503 and flow meters 502 of different specifications. Electronic display vacuum gauges 302 of different specifications are installed on the placement panel 301. During measurement, all valves on the surface of the flow meters 502 and the vacuum valves are closed first. The vacuum pump is started and run to the ultimate vacuum state, which can be observed through the vacuum gauges on the tank 2. After the ultimate vacuum is reached, starting from the flow meter 502 corresponding to the smallest range vacuum valve 503, the valves on the flow meter 502 are opened and closed in sequence, and the data is recorded through the vacuum valve 503. Then, the valve of the flow meter 502 corresponding to the current vacuum valve 503 is closed, and the valve of the flow meter 502 corresponding to the next range vacuum valve 503 is opened for measurement and recording. After all the data is recorded, these values ​​are entered into a table to generate the pumping speed curve, thereby completing the measurement of the vacuum pumping speed.
