How to maintain a hydraulic universal test machine

Some things to pay attention to during daily operation of the test machine, which can better maintain and extend the service life. Let’s share with you the daily maintenance of the hydraulic universal testing machine.

Testing machine should pay attention to some issues in daily operation,can better maintenance, prolong the service life, the share of hydroulic universal testing machine daily maintenance matters with you,

1. All parts of the test machine should be wiped clean frequently. Wipe the surface without spray paint cleanly and apply cotton yarn dipped in a small amount of engine oil to prevent rust.

The 1 test machine should always wipe clean, the application of no paintsurface wipe clean after cotton dip a small amount of oil and then wipe it again, to prevent rusting,

During the rainy season, you should pay more attention to wiping, and use a dust cover to prevent dust from entering when not in use.

During the rainy season should pay attention to cleaning, when not in use and dust cover to prevent dust intrusion.

2. All shutters on the control cabinet should not be opened and placed to prevent dust from entering the interior, affecting the sensitivity of the measurement mechanism and easily causing short circuit aging.

2 control cabinet all valve should not be open place, so as to avoid dust entering the inner, sensitivity measurement mechanism caused by short circuit aging effect.

3. Long-term frequent use may lead to a decrease or deterioration of the oil. The amount of oil should be checked every 1-3 months according to the use situation. After the equipment is stopped for 15 minutes, observe the oil window.

3 may lead to reduce the amount of oil or deterioration frequently used for a long time, should according to the use of every check 1-3 months of the first oil. This equipment is stopped after 15 minutes, to observe the oilwindow,

If the oil level is lower than the oil window, add the same hydraulic oil to the middle of the oil window; if the oil has deteriorated, new hydraulic oil must be replaced.

If the oil level is lower than the oil window is added to the sameintermediate position of the hydroulic oil to the oil window; if the oil has been deterioration, must put on new hydroulic fluid.

4. Frequent use of this equipment for tensile breaking tests may cause some fasteners to loosen.

4 the frequent use of the equipment to do the tensile breaking test may lead to some loose fasteners.

5. Lubricate the following parts every 3-6 months according to environmental conditions and frequency of use:

5 according to the environmental conditions and the frequency of use,every 3-6 months for the lubrication of the following parts:

6. There are two jaw clamps for installing jaws on the upper crossbeam and the mobile crossbeam, which are important parts of this machine. The debris on the contact surfaces between the jaw clamps and the beam should be frequently removed according to the use situation to avoid lashing the contact surface. The method is: remove the press plate on the side of the moving beam, take out the jaw clamp, use an oil rag to clean the contact surfaces of the jaw clamp and the beam, apply an appropriate amount of butter and graphite mixed grease, replace the jaw clamp and tighten the fixing screws of the press plate.

6 beam and the moving beam on each jaw clamping device with 2 jaws, is an important part of the machine, should according to the use of often remove jaw clamping plates and the crossbeam on contact surfacedebris, so as to avoid rough contact surface. Method: remove the sideplate is moving crossbeam, remove the jaw clamp, oil cloth respectively contact surface of the jaw plate and beam clean, coated with an appropriate amount of butter and graphite mixed fat, fixed screwtightening clamp jaw clamping back after.
