Hydraulic cylinders have what matters need to be checked frequently

Hydraulic oil is the use of liquid pressure can be used in hydraulic systems using hydraulic media, hydraulic cylinders to normal operation use is less hydraulic oil, so the use of oil state is very important. However, it should be noted that before starting the machine, check the oil level, check whether the switch of each oil circuit is in the correct standby state.

Machine idling for about 5min, check the level meter oil whether there are bubbles present, if it is a new car or a new replacement of the hydraulic oil, idling oil bubbles in the oil mark is normal, wait for the bubbles to disappear before allowing the machine to operate. At the same time to pay close attention to the temperature of the oil, when the machine works for a period of time, if the oil temperature is high it is recommended to stop the machine and rest, until the oil temperature is normal and then re-work, in order to prolong the service life of the system and the oil.

Should pay attention to the various parameters of the hydraulic system value is normal, but also must pay attention to the external characteristics of the system - sound. If the system inlet air, water or oil circuit is not smooth, etc., will issue a strange sound. At the same time the meter reading fluctuation display value is not normal, this time should be timely shutdown, troubleshooting.

In order to protect the normal operation of the hydraulic cylinder, the hydraulic oil needs to be filtered regularly, so that the impurity particles in the oil are controlled within the prescribed range. In accordance with the requirements of the machine instructions for regular oil changes, while replacing the oil filter, there are conditions for testing, should be based on its results to determine whether the oil change; also according to the use of machinery site and system requirements to develop the oil change cycle, and the oil change cycle into the technical file of the equipment.

Hydraulic oil in the hydraulic system plays a role in energy transfer, anti-wear, system lubrication, corrosion, rust, cooling and so on. In order to better protect its use of state, before and after the use of the need to do a good job, so that the hydraulic cylinder can also have a better make operation state.
