How to maintain a hydraulic universal testing machine

For multi-performanceHydraulic universal testing machine, Every customer uses it ingeniously and will do effective maintenance after work.

For the hydraulic performance of the universal testing machine, each customer is the clever use of, in the work will make effective maintenance,

1. During the test, when the oil pump suddenly stops working, the oil pump should be opened immediately to remove the sample. It is prohibited to start the oil pump on the high-voltage line or check the cause.

1 during the test, the pump suddenly stops working, should immediately open the pump unloading samples, no startingpump or check reason in the high-voltage wire.

2. During the test, the electrical appliance suddenly fails and the start or stop buttons do not work. The power supply should be cut off immediately to stop the machine.

2 in the process of test, electrical appliances suddenly failure,start or stop button does not work, should be immediately cut off the power, stop the machine.

3. The function of moving crossbeam is to adjust the test space. During the experiment, it is strictly forbidden to start the moving measurement when applying force and unloading force, otherwise it may cause the lifting and lowering driving mechanism to fail.

3 the moving beam's role is to adjust the test space, in the experimental process, strictly mobile measure start unloading force in force and time, otherwise it may lead to failure of the lifting driving mechanism.

4. When installing a bent support by hydraulic universal testing machine, pay attention to calculating the distance between the support. The engraving line on the support is the position of the center line of the roller. Incorrect calculations may cause the connecting rod connecting the two support to be broken.

4 hydroulic installation bending support universal testing machine when calculate the bearing should be betweendistance, bearing on the line for the roller center position, the calculation error may cause the connecting rod bearing offwo.

5. For models equipped with hydraulic chucks, the power supply of the oil pump motor should be cut off first when changing the jaws to avoid damage caused by error operation.

5 for a hydroulic chuck type, should first cut off the power of pump motor in the replacement of the jaw, so as to avoid the error operation of the hydroulic chuck movement damage.

6. All parts of the test machine should be wiped clean frequently. Wipe the surface without spray paint and apply a quantity of cotton yarn sand to prevent rust. Pay more attention to wiping during the rainy season. When the instrument is not suitable, use a dust cover to prevent dust from invading.

The 6 test machine should always wipe clean, the application of cotton yarn sediment no paint surface wipe clean oil to rub it again, in order to prevent rust, during the rainy season should pay attention to clean, do not apply when the dustcover to instrument application of dust prevention intrusion.

7. It is prohibited to operate the superiors of the aircraft staff
