Precautions for replacing hydraulic oil filter element:

(1) Installed at the suction port of the hydraulic pump, installing an oil filter at the suction port of the pump can protect everything in the system

There are components, but due to the limitation of pump suction resistance, only mesh oil filters with low pressure loss can be selected. this

The oil filter has low filtration accuracy, and particles generated by pump wear will enter the system, affecting other hydraulic components in the system

Unable to provide protection, other oil filters need to be connected in series on the oil circuit for use.0110D003BN/HC is suitable for hydraulic oil filter cartridges in construction machinery

(2) Installed on the oil outlet of the hydraulic pump, this installation method can effectively protect other components besides the pump

Hydraulic components, but as the oil filter operates under high pressure, the filter element needs to have high strength to prevent

When the oil filter is clogged and causes hydraulic pump overload or damage to the oil filter, a blockage indicator is often installed next to the oil filter

Or protect it with a bypass valve.

(3) Install the oil filter on the return oil circuit of the system. This method can integrate the system

Filter out particles generated by the detachment of the oxide layer on the inner fuel tank or pipe wall, or the wear of hydraulic components, to ensure the safety of the fuel tank

The cleaning of the internal hydraulic oil protects the pump and other components. Due to the low return oil pressure, a strong oil filter is required

The degree is not high.

(4) Installed on the branch, this method is mainly installed on the return oil path of the overflow valve, which will not increase the main oil

The pressure loss of the road and the flow rate of the oil filter can also be less than the flow rate of the pump, which is more economical and reasonable. But it cannot filter

All the oil cannot guarantee that impurities will not enter the system.

(5) Separate filtration, using a hydraulic pump and oil filter to form a separate and independent filtration system outside the system

Road, this can continuously remove impurities from the system and ensure its cleanliness. Generally used for large hydraulic systems

1. Familiar with the working principle, operating procedures, maintenance and usage requirements of hydraulic systems, and have a clear understanding of them

Blindly acting recklessly.

2. Prepare new oil according to the instructions, and allow it to settle for at least 48 hours before use.

3. Prepare tools for disassembling various pipe joints, oil filters for adding new oil, hydraulic system filters, etc.

4. Prepare cleaning solution, brushes, and silk cloth for wiping.

5. Prepare the oil stick for storing waste oil.

6. Choose a flat and solid site to ensure that the machine can rotate under the working conditions of bucket and arm arm extension

Accessibility, the boom should not touch any obstacles after lifting, and the distance from the power line should be greater than 2 meters.

7. Prepare 4 sleepers to block the tracks forward and backward.

8. At least 4 operators are required, including 1 driver, 1 on-site commander, and 2 oil change personnel.

2、 Oil change method and steps

1. Place the boom parallel to the track direction and stop at a 45 ° left turn position to allow the bucket cylinder piston rod to move

*Extend, retract the piston rod of the stick cylinder, slowly lower the boom, and place the bucket on the ground

Turn off the engine, open the fuel tank vent valve, and turn back and forth on each operating handle and pedal several times to release the pressure

System residual pressure caused by self weight and other factors.

2. Clean all pipe joints, pump and motor joints, drain plugs, top and bottom fuel tank caps with gasoline *

The oil drain plug and its surroundings.

3. Open the drain valve and the drain plug at the bottom of the fuel tank to allow all the old oil to flow into the oil drum containing the waste oil.

4. Open the fuel cap of the fuel tank, remove the fuel filter element, and check the residual oil at the bottom, edges, and corners of the fuel tank

Does it contain metal powder or other impurities. *Clean the fuel tank, first clean it twice with diesel, and then use

Compressed air blows dry the inside of the fuel tank. Check for residual oil sludge, impurities, etc. at the internal corners until

Clean thoroughly before rinsing with new oil.
