Cleaning the hydraulic oil is important for the life of the hydraulic power unit . There are many sophisticated hydraulic power unit coupled parts, and some damping holes, and some have cracks and so on.

If solid impurities will result in the invasion of precision coupling strain, card, oil channel blockage, endangering the safe operation of the hydraulic power unit , the invasion of the hydraulic power unit of solid impurities in the general way: hydraulic oil unclean; refueling tools dirty; refueling and maintenance, maintenance accidentally; scaling and other hydraulic components.

Available from the following aspects of solid impurities intrusion prevention hydraulic system:

1.To protect the hydraulic power unit for impurity while adding hydraulic oil:

The hydraulic oil must be filtered when the fuel filling, fuel cleaning tools should be reliable. In order to improve the speed can not be removed fuel tank filler at the filter. Refueling should use clean gloves and overalls, to prevent solid impurities fall into the oil and fiber.

2. The protection of the hydraulic power unit while maintenance:

Maintenance of the hydraulic oil tank when the fuel cap removal, filter cover, test holes, hydraulic tubing and other parts, causing the system to avoid the oil path when exposed to dust, demolition site must first be opened after a thorough cleaning. Such as the demolition of the hydraulic oil tank cover, first remove the soil around the tank cover, screw pine oil cover, clear debris left in the joint of bits (not water rinse tank to prevent water infiltration), confirmed to open the fuel tank after cleaning. To use cleaning materials and hammer should be selected impurities can not afford to wipe the fiber surface attached to the rubber material and hit the special hammer, in hydraulic components, hydraulic hose to wash carefully, dry wind with high-pressure assembly.

Genuine filter selection packaging intact (the packaging is damaged, although the filter in a good condition, may also unclean.) Oil change, clean the filter at the same time, installing the filter before the application materials carefully wipe clean the filter shell and the bottom of the dirt.

3.The cleanliness of hydraulic power unit

Cleansing oil to clean the hydraulic power unit must use the same system used in grade hydraulic oil, oil temperature between 45 ~ 80 ℃, with a large flow away as possible impurities in the system.

Repeated cleaning of the hydraulic power unit to more than three times, each time after washing, while oil heat will release all of its systems, then clean the filter cleaning is completed, replace the new filter after filling the new oil.
