Waterproof coil impermeable meter

 

First, overview

Waterproof coil electric impermeable meter is designed according to the requirements of the People's Republic of China national standard GB/T328.10-2007 "Petroleum asphalt paper tire felt, oil paper asphalt waterproof coil test method", this product has a simple operation method, automatic pressure, automatic pressure, automatic timing, automatic alarm after the test time. It has the characteristics of maintaining constant pressure automatically.

Uses

It is mainly used for the quality acceptance and arbitration test of petroleum asphalt paper tyre felt and other waterproof materials allowed to adopt this standard.

Second, technical parameters

  1. Power supply voltage: 220V
  2. Working voltage: 220V

3, power rate: 60W

4, the number of tests: 3 pieces (a group)

  1. Working pressure: 0.1MPa

6, the maximum pressure: 0.6MPa

7, working time: 999 minutes arbitrary setting

8, the test time is finished, automatic alarm, the machine no longer continue to work

Third, the use of

  1. Cut the material to be tested into 3 ¢140mm circles for special use.

2, the 20±5℃ of distilled water or clean fresh water slowly poured into the three permeable tray close to the overflowing state of the round test pieces were placed on the permeable tray, and then the hole of the round pressure sheet on the top, with the pressure plate on the screw.

3, open the valve of the water injection port, fill it with water and then tighten the cover.

4, adjust the pressure gauge (according to the requirements of the upper node to 0.1, the lower contact to 0.05, the factory has been adjusted.

5, time setting, according to the experimental requirements to set the time. For example: to test for 30 minutes, first press the set key, so that the one is 0, then press the set key to ten, press the plus key to make the ten is 3, and then press the start key, the instrument begins to pressurize, when the pressure reaches the set pressure, the machine automatically stops pressurizing, and at the same time, the counter begins to time, such as the test time reaches 30 minutes, the machine automatically stops.

6, when the pressure reaches the set pressure, the timer begins to time the work, if in the effective test time, again automatic pressure, pressure, timer normal timing, not affected by pressure and pressure.

7, after the test is completed, open the water drain valve, discharge the pressure and water, unscrew, remove the specimen, and wipe the test disc clean.

8, in addition to the power supply and transformer, the control circuit adopts high voltage (DC220V), and the electrical equipment should pay attention to the voltage of the device during maintenance.

After each test, the water should be released and wiped clean to keep the equipment clean.
