system compsition:

The instrument consists of pressure source, pressure host and computer software system.

Pressure source:

Main function is to provide pressure host pressure, pressure station requirement is lower limit must be higher than that of all samples tested by pressure, this part USES the large flow, low n oise, high pressure plunger pump, free maintenance, through the external pressure of demineralized water, able to complete the automatic filling water, ensure the reliability of the total pressure, become one of the most reliable source of pressure. Pressure host:It is composed of pressure micro control part, automatic pressure supplement and electric pressure relief part. The pressure micro control part is controlled by microcomputer MCU, equipped with high resolution and high speed ∑-△ 16-bit ANALOG-to-digital conversion chip, and the computer can communicate constantly, and can automatically fill and relieve pressure according to the pressure situation. 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.

Attentions:

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.

Specification 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.

oubleshooting and troubleshooting:

Matter

Reason

Solution

Host cannot displayed.

No power supply

Check whether the power supply has voltage

Pressure supplement exceeds the upper limit or cannot limit pressure rise

Solenoid valve due to water quality and loose, or long-term use has been damaged

Clean the solenoid valve

Clean water treatment equipment regularly

Replace solenoid valve

 

Equipment maintenance:

1)It is strictly forbidden to turn on the power supply of pressure station before filling water reservoir;

2)When filling the specimen with water, the exhaust valve must be opened first, otherwise the water will not be sufficient;

3)The specimen will be rounded at both ends before loading the fixture, otherwise the sealing ring will be damaged;

4)When the host is in use, it must be noted that if the instrument is powered on, it must be turned on for 3 minutes before the power can be turned off, and it must be powered on again after 1 minute after the power is turned off. If this operation is not followed, it is easy to appear the phenomenon of communication failure, and the responsibility is the responsibility of the user;

4)When the pressure station does not reach the set pressure, it is forbidden to press the pipe;

5)In any road charging process (that is, the pressure is not constant), it is strictly prohibited to charge other roads immediately, which will lead to insufficient pressure supply at the pressure station and prevent other roads from being affected;

6)Because of the existence of water tank, please install ventilation equipment in the laboratory, too high humidity is easy to affect the surface and internal electrical parts of the instrument, shorten the service life;

7)Because the instrument is equipped with a pressure relief device, so the supporting pool must have a sewer pipe, the laboratory to maintain a state of no water.

8)When pressing the cleaning button, the compensating pressure solenoid valve and pressure relief solenoid valve are always in working state, please stop in time to prevent the solenoid valve coil overheating, solenoid valve failure.
