GB/T 6111-2003 Hydrostatic High Pressure PVC Pipe Bursting Machine

GB/T 6111-2003 Hydrostatic High Pressure PVC Pipe Bursting Machine

Software system :It is connected to the pressure host through the RS232 serial interface of the computer, and provides various functions such as parameter setting, calibration, pressure relief, zero adjustment, amplitude modulation, test curve drawing, test record storage and test report printing.

Limitations and description of instrument use:

1)The use of the instrument must meet the following conditions can be tested.

2) Ambient temperature: within the range of 10℃ ~ 40℃;

3) Relative humidity of the environment within 30% - 80%;

4)No vibration around, no corrosive medium environment;

5)Correctly installed and levelled on a firm foundation;

6) There is no strong magnetic field interference and no strong convection in the surrounding air.

1.2 Attentions:

• Please read the instruction manual carefully before use.
• Do not place the instrument in an unstable place.
• Use the instrument under specified power conditions.Do not place anything on the power cord, and do not place the power cord of the instrument where people can step on it. If an extension cord is used, ensure that the extension cord is consistent with the current rating of the original wire.
• In order to prevent electric shock, do not repair the instrument by yourself. Opening or removing the housing may pose a high pressure hazard. When the instrument is not tested or repaired for a long time, please turn off the power to avoid accidents.
• The instrument should be convenient around the water and drainage, do not put the instrument in the vicinity of often water, to prevent electrical corrosion by moisture.
• When filling the sample with water, the upper end of the fixture is strictly prohibited to run the air hole at the person, when the high pressure water spatter is easy to hurt people, especially when clamping the sample at high temperature, it is strictly prohibited to take ordinary cotton gloves, it is necessary to take waterproof and heat insulation gloves.
• In the sample clamping, it is strictly prohibited to dip into the water tank cover can reach the place.
• At the end of the test, it is necessary to click the save button of the road to save the experimental data into the database of the computer by the temporary storage unit, otherwise the new test can not be carried out on the road.

1.3Specification and installation

System working pressure: 0~10 MPa (0~16MPa and 0~20MPa need to custom)

Pressure fluctuation:-1%~2%

Pressure indexing value:0.001MPa

Timer working time:0~10000 hours

Timing error:±0.1%

Instrument storage conditions:

1)The instrument and its accessories must be kept in a dry environment.

2)No vibration around, no corrosive medium environment.

3)No strong extrusion around the environment, no damage to the instrument.

4)The base of the instrument is installed with a caster. After releasing the foot brake plate controlling the caster, the instrument can be pushed to an appropriate position and locked.

Power supply:

The host:220(1-15%)VAC～220(1+10%)VAC,50Hz, 1.0kW

pressure station:380(1-15%)VAC～380(1+10%)VAC 4.0kW

Inspection before using the machine:

1)Check whether the power cable and signal cable are plugged in tightly.

2)Whether the high-pressure hose connection between the pressure host and the pressure station, the pressure host and the water tank is reliable.

Safety warning during maintenance:

Do not operate with the power on when removing or installing the panel. Remove the power cable before the operation.
