There are many hydraulic components on construction machinery, and sufficient hydraulic oil is required. When the hydraulic oil needs to be replaced due to its deterioration after a long time of use, some people mistakenly believe that only drain the oil in the hydraulic oil tank and fill it with new hydraulic oil.

However, there are still many old hydraulic oils left in the hydraulic oil pipe and hydraulic control valve at this time. When the equipment is used, the mixing of new and old oils will speed up the deterioration of new oils.

The correct oil change procedure should first drain the hydraulic oil in the hydraulic oil tank, clean the oil tank and add new hydraulic oil, then remove the circuit header, start the engine and run at low speed to make the oil pump work, operate each mechanism separately, drain the old oil in the circuit one by one with the hydraulic oil until new oil flows out of the oil return header, and then connect the oil return header to the oil tank, Add new hydraulic oil to the oil tank to the specified position.

Foshan Fuchao Oil cylinder manufacturer Hydraulic Electromechanical Equipment Co., Ltd. is a hydraulic machinery manufacturing enterprise integrating design, development, production, sales and service. With professional processing equipment and strong technical force, we can design special non-standard hydraulic machinery, non-standard oil cylinders and Hydraulic system 。

Our company follows the service concept of "treat people with integrity, quality first, customer first", and the pioneering spirit. Improve the production process by integrating the professional technology of similar products at home and abroad.

Of course, this oil change also has its disadvantages. Let's say the loader with pilot. When the oil is changed in this way, the pilot oil pressure will be 35kg when the machine is idling first. The pilot oil (that is, the newly changed oil) will arrive at the oil return pipe just after the machine is started. Even three large barrels of hydraulic oil may not be enough. In addition, there is not only one oil return pipe, which needs to be removed one by one, which is troublesome to do one by one.

As the saying goes, "sharpening the knife will not hurt the firewood cutter". Don't be afraid of trouble, friends!

The company will be excellent products, fast time. Fuchao Oil cylinder manufacturer Good reputation to provide users with satisfactory service. Warmly welcome individuals from enterprises to visit our company for business negotiation and common development.

Imagine that although the oil change is a little slow, it depends on the specific model and situation, but at most half a day to one day is enough. How much money can this equipment earn on that day? If a component is damaged due to dirty oil, how much money will spare parts cost you besides maintenance man hours and costs? This is not alarmist!
