Bellows sealing tester
PIC-(Bellows sealing tester)
1、 Introduction:
This machine is developed and produced in accordance with the technical requirements of JT/T529-2016 "Corrugated Pipes for Pre stressed Concrete Bridges" issued by the Ministry of Transport of the People's Republic of China, to measure the sealing performance of various types of corrugated pipes. Equipped with vacuum pump and digital negative pressure sensor, as well as various conical rubber plugs and dedicated clamping workbenches.
2、 Technical parameters
Vacuum pump power: 2.2kw
Voltage: 220/380 AC
Negative pressure accuracy: 0.01 KPa
Overall weight: 130 kg
Touch screen: 10.1-inch
Special workbench appearance: 1000 * 700 * 450 mm (length * height * width)
Control cabinet appearance: 350 * 1200 * 450 (length * height * width)
Supported specimen specifications: ripple types 50-60-75-90-100 115-130
3、 Test method:
Install the two corrugated pipe joints, pipe joint joints, and connecting heads and place them in dedicated work. Seal both ends with tapered rubber plugs of appropriate specifications. Then the screw applies a certain force value to the rubber plug to ensure reliable sealing of the conical rubber plug. Connect the exhaust hole of the pipe joint to the vacuum pipe. Start the vacuum pump to measure the vacuum degree. A vacuum degree not exceeding -0.07mp is considered qualified.
Control interface
4、 Control interface functions:
1: Real time display of negative pressure curve (refreshing once per second and continuously recording for 2 hours)
2: Simulated negative pressure gauge display for easy observation.
3: Animated indication of vacuum pump start stop for more intuitive operation.
4: Synchronize timing, start timing immediately upon startup. (0-9999s)
5: RTC clock function
6: No mechanical buttons - touch operation.
