Aquaspring focuses on designing Hot Tubs for different groups of customer. Considering that there are many customer groups, including dealers, hotel owners, and self-use buyers, we have specially classified these hundreds of hot tubs so that various customer groups can quickly look for the right models. As the title suggests, these hot tubs, whether small or large, are all high-end hot tub spas. These models of hot tubs are novel in style, spacious and comfortable inside, equipped with a larger number of massage nozzles, and have a more comprehensive and diverse massage experience. If you have enough budget, these luxury hot tubs are an ideal choice. At the same time, we also provide a variety of functional accessories as options, such as speakers, aroma feeders, ultraviolet disinfection, a variety of styles of skirt decoration, etc., to provide you with a richer soaking experience. deluxe jacuzzi tubs,luxury jacuzzi,best jacuzzi,deluxe hot tub,best luxury hot tubs Foshan Nanhai Halo Sanitary Ware Co., Ltd. , https://www.halospas.com
Insertion force test machine test example operation instructions
**Insertion Force and Pull Force Testing Machine Operation Guide**
**1. Insertion Force Test**
- **Measurement Mode**: Choose the two-way measurement mode. The speed can be set between 1 to 300 (standard machine speed). The number of tests can be adjusted from 1 to 10,000,000. Make sure to "Start measuring position" and check the origin once before beginning.
- **Clamping**: Insert the male and female connectors of the test product into the clamp. Ensure the clamp is vertical and the automatic centering device is near the center. Avoid any misalignment that could affect the auto-centering function or damage the device.
- **Load Zeroing**: After clamping, zero the load and press the move button to separate the male and female ends slightly, without fully removing them. Observe the display to ensure proper movement.
- **Stroke Setting**: Set the test stroke to be less than the actual stroke by 0.1–0.2 mm.
- **File Saving**: After setting all parameters, click “File,†then “Pre-set Storage†to save the file. The file name should only contain letters, numbers, periods, or hyphens — no spaces allowed.
- **Test Execution**: Start the test on the screen. If the stroke cannot be found, use a height gauge to measure the insertion stroke of the male plug, adjust the connector positions, and set the stroke accordingly. Ensure the set stroke does not exceed the actual measured stroke. The starting position is also critical for accurate results.
**2. Break Test**
- **Clamping**: Clamp the test product in the upper or lower clamp. Adjust the height so that the product is properly secured.
- **Test Mode**: Switch to “Break Test.†Set the stroke based on the actual stroke of the product to ensure it can be completely pulled out.
- **Parameters**: Set the speed and number of cycles, then save the file.
- **Return to Zero**: Return to zero, but do not return to zero after clamping.
- **Perform Test**: Execute the test on the screen.
**3. PIN Test**
- **Sensor Connection**: Connect the sensor interface with the test rod and lower the fixture, adjusting the position as needed.
- **Range Settings**: Set the load range to be greater than the maximum force the PIN can exert. The stroke range should be less than the stroke of the PIN above the insulation surface to avoid missing the actual force value during testing.
- **Zero Position**: Select “Load Zero Position (only when force starts counting)†and each time the origin is detected. Save the settings.
- **Test Execution**: Begin the test. Alternatively, you can use the one-way measurement mode, which will result in a black return force curve.
**4. Constant Pressure and Tensile Test**
- **Mode Selection**: Choose “Constant Pressure†mode. The software will automatically open the “Force†and “Time†data frames. Fill in the required force and time values, then save the file.
- **Clamping**: Secure the test product and adjust its position.
- **Test Execution**: Perform the test. When the set force is reached, timing begins, and the test stops after the set time is completed.
- **Constant Pull Test**: Similar to constant pressure, but without the return stroke. These tests are slower, typically around 30 seconds per cycle.
**5. Longitudinal Force Test**
- **Zero Position**: Select “Load Zero Position†and detect the origin each time. Set the unit to grams.
- **Test Rod**: Use the appropriate test rod for the test head.
- **Position Adjustment**: Adjust the position and test the corresponding stress value at different strokes.
- **Customer Request**: Some customers need the stress value at the bottom point of the stroke. In such cases, contact the after-sales technician for assistance.
**6. Load-Displacement Test**
- **Setup**: To test how much deformation occurs under a certain force or what force is applied during deformation:
- Set the load measurement range to the required force and ensure the stroke is large enough.
- Select “Load Zero Position†and detect the origin each time.
- Set the speed (usually around 30), number of cycles, and save the file.
- Perform the test and observe the waveform. The imax value represents the required stroke.
**7. Contact Resistance Test**
- **Settings**: Configure the test parameters similar to the insertion force test.
- **Resistance Measurement**: Select the insertion point resistance value in the last column of the measurement item.
- **Clamping**: Clamp the male and female connectors using the impedance test fixture.
For additional tests such as anti-bending test, peel force test, displacement load test for shrapnel switches, constant tensile life test, and break force measurement, the milligram brand insertion force testing machine can perform these tasks. For detailed operation instructions, please contact Wei Jia at 15995758658 or via QQ 853803917. Note that the above methods apply only to the milligram brand insertion force testing machine with a patent certificate.
