Fire rescue ladder oil change precautions

1) In order to completely drain the used oil or flush oil, the following steps should be carried out.

After the hydraulic oil stops flowing from the tank drain hole, the oil on the side of the oil storage tank should not be discharged immediately in order to further drain the oil

Screw the drain cock into the drain hole and continue to maintain the oil discharge state for 3 to 5 minutes. The oil discharge hole of the piston side oil chamber of each cylinder is directly connected with the tank or oil pan, and then the tank is activated to discharge the hydraulic oil.

2) During the flushing operation, the hydraulic oil should flow in the same direction.

3) During the flushing operation, in order to make inclusions such as oxidized products on the pipe wall easy to flow, slight tapping of the pipe is also a method that can be taken.

4) All disassembled tubing must be replaced with a seal. (0 ring) When connecting, the thread surface should be coated with thread sealant to prevent leakage.

5) The quality requirements of hydraulic oil: the service life of hydraulic oil is directly related to quality, to choose the quality of hydraulic oil to meet the national quality standard certification, this hydraulic oil at 40°~100 ° C viscosity index is stable. The new hydraulic oil needs to be purified

6) First apply the minimum operating pressure, and then gradually turn to normal operation, according to this state for 1 to 1.5 hours after 4 hours of injection.

7) After turning to normal operation, check the degree of adhesion of dust on the filter element of the oil filter every 3 to 4 hours, if running. When there is no dust and other inclusions on the oil filter element during inspection, the washing operation can be completed. At this time, such as circulating pipeline oil filter

If the device is temporarily installed, it can continue to operate after being disassembled.

8) After filling the oil tank with new oil and starting the operation of the hydraulic system, the hydraulic oil flow into the cylinder and other devices will cause

9) The service life of hydraulic oil: the life of static hydraulic oil is about two years. In the spring and autumn of each year, the amount of oil in the oil storage tank is reduced, so don't forget to fill the hydraulic oil. The temperature difference between day and night is large, after the vehicle stops working at night, the oil inside the hydraulic tank is high temperature, the air outside the tank is low temperature, the hot air in the tank and the cold air outside the tank meet and contact, it will be cold condensed into water droplets falling in the hydraulic oil at the top of the tank, and over time, the wave pressure oil will be mixed with water. It then turns into an acid that eats away at the metal surface. Under the double action of mechanical operation and pipeline pressure impact, the metal particles falling off the metal surface will be mixed in the hydraulic oil, the large metal particles are filtered out, and the particle hydraulic filter element of less than 10mm can not be filtered out, and the grinding particles mixed in the hydraulic oil will aggravate the wear of the metal surface again. Therefore, in the idle state, the vehicle should not be placed outdoors (especially in cold areas in the north), and at the same time, the filter should be changed frequently.

10) The selection of the design service is required to have a filtering accuracy of not less than 20m(our company can provide the corresponding for.

The recommended replacement time is 500 hours.
