Hydrostatic Pressure Test Machine

Product Details

Features  Accurate testingTest results are highly consistent with international third-party testing institutions and receive positive feedback from customers in over 60 countries. Servo motor control, stable operation, and longer lifeClosed loop control with servo motor-driven piston for a unique water pressure rise rate balancing system. In addition, the booster system has dynamic feedback adjustments to prevent overload. Multiple testing methods, more practicalDifferent test methods can be selected and test times and variable boost rates can be set and saved. There are three test methods, i.e. boost mode, constant voltage mode, and constant voltage timing mode, to meet various needs. Rapidly produce test results and output reportsEquipped with LED lights for easy observation of the testing process; real-time test results are displayed on the large color touch screen; test results can be formed into reports on the software and printed out directly.

The fabric is subjected to a continuous rise in water pressure until water beads up on the back of the fabric under standard atmospheric pressure. At this point, the measured water pressure value is the hydrostatic pressure. Because the greater the hydrostatic pressure that the fabric can withstand, the better the waterproofness or resistance to seepage. Hydrostatic pressure units The hydrostatic pressure can express in N/㎡, Kpa, and water column height m. And the conversion unit is 1m water column height equals 9.82Kpa. Precaution and Maintenance 1 Before the first operation, the operator must read the Operation Manual carefully and receive special technical training. 2 Sweep the upper chuck lightly before placing the specimen to avoid affecting the test results. 3 The default value of the cylinder is 0.5MPa (can adjust according to the characteristics of the specimen). The maximum error range should not exceed plus or minus 0.2MPa. 4 The inlet pressure should be less than 0.8MPa but the maximum pressure should not exceed 1MPa. 5 Turn off the power and then remove the plug from the power outlet after each test. 6 Emergency stop and restart the instrument in case of malfunction. 7 In order to ensure the normal operation of the machine, the user must regularly check the water level of the test tank. Meanwhile, drain the water out if the machine will keep idle for a long time. You, therefore, need to turn on the drain switch (horizontal direction to the outlet pipe) and by all means, avoid wetting the electrical equipment. After completing the drainage, close the drainage switch (vertically to the outlet pipe) and check that the drainage switch and the pipe mouth must not fall off. 8 Keep the touch screen away from sharp hard objects. 9 No strong electromagnetic interference in the surrounding.
