Maintenance and care of hydraulic system for Drill Rig machine
Proper use and maintenance of hydraulic system is the most important work in the use of full hydraulic drilling rigs, and is an important guarantee for the normal operation and extended service life of full hydraulic drilling rigs.
1. Precautions for installing oil pipes in hydraulic system:
(1) The oil suction pipe should not leak, and each joint should be tight and well sealed;
(2) A filter should be installed on the oil suction pipe;
(3) The return oil pipe should be inserted below the oil level of the oil tank to prevent splashing foam and mixing with air;
(4) The leaking oil in the electromagnetic reversing valve must be equipped with a separate return oil pipe to prevent back pressure when the oil is leaking back and avoid hindering the movement of the valve core;
(5) The return oil port of the overflow valve is not allowed to be connected to the inlet of the hydraulic pump;
(6) All pipelines should be installed twice, the first test installation and the second formal installation. After the test installation, remove the oil pipe, pickle it with 20% sulfuric acid or hydraulic acid solution, then neutralize it with 10% soda water, and finally wash it with warm water. After drying, apply oil for secondary installation. Be careful not to have sand, oxide scale, etc. during installation.
