One, hope: see what.
1, see the system configuration is normal, including: pumps, valves, actuators, working oil, oil filters, radiators, etc.;
2. Look at the speed (flow): See if there is any abnormality in the speed of the actuator;
3, look at the pressure: look at the pressure value of the hydraulic system pressure measurement points and fluctuations;
4. Look at the oil: Observe whether the oil capacity is appropriate, whether it is clean, whether there is deterioration, whether there is foam in the oil, etc.;
5, see leakage: Look at the hydraulic pipe joints, valve plate joints, hydraulic cylinder end cover, hydraulic pump shaft protruding whether there is leakage, drip and grease phenomenon.
Second, smell: What to hear.
1, to listen to noise: to determine whether the sound heard is a noise, where the source of noise, hydraulic pumps, motors, valves and other hydraulic components or system piping or work units connected to the components.
2. Listen to the impact: whether the system's impact sound is normal.
The impact of the sound of time: the impact of the hydraulic valve when the change, or inexplicably sound.
The regularity of the impact sound: rhythm or no law.
3. Listen to leaks: Listen to the oil road for subtle, continuous sounds.
4, listen to tapping sound: listen to whether the hydraulic components running when the sound.
5, listen to relevant personnel to reflect.
Third, touch: What to feel.
1, touch temperature rise: touch the surface of moving parts, check whether the fever.
2, touch the vibration: the feeling of vibration phenomenon.
3, touch crawl: feel the movement of the "crawling" phenomenon.
4, feel tightness: check the tightness of the threaded connection.
5, touch tightness: Invisible places, check for oil leakage.
Fourth, cut: use a pressure gauge to judge.
1. Is the pressure value in various places normal: the pump's oil absorption and output, the motor's oil inlet and outlet, the oil pressure in the two-chamber oil tank, the working pressure of the valve, and the control pressure;
2, whether there is pressure fluctuations, whether the fluctuations in the design range.
Fifth, use smell to judge.
1. Smell the oil if it smells bad;
Old cars: The use of a long time, oil components will degenerate, smell and other strange smell,
New car: Check if there is any misoperation in refueling and prevent misfueling.
2. Whether the system smells odor or not, where it came from.
