Spool valve, pump and motor shaft are allowed to dry can be affected by rust and corrosion on the climatic conditions are unfavorable. If the vehicle is stored outside, it is recommended to coat all exposed surfaces by using grease protective paint if not used immediately. A crucial step in the care of the vehicle using hydraulic equipment is to mengcat. The paint protects the surface of the vehicle, and also can dazzle the eye. Overall cleaning and preparation to be done properly, because of damage to the hydraulic system components could occur.
All piston rods are exposed to the weather should be wrapped with protective tape. Paint can damage the sealing element on the cylinder cover and can cause leakage when the piston rod is pulled. At the time of the motor and pump shaft seal located outside the hull trust bearing, it is important to make sure that the seal is also protected.
All spool control valves, including an open end capped and holes flow should be closed prior to painting. Cleaning dirt, oil and grease is usually done by volatile mineral spirits or paint thinner other, which can be sprayed and allow to dry before painting. Most of the direct control valve (directional) has a door (port) cylinders are blocked in the neutral position and the oil in the cylinder can not be compressed.
During transport, the cylinder may be exposed to mechanical shock loads. To prevent damage, use a buffer of hardwood to prevent movement of the piston rod during transport. Try to keep the equipment with the cylinder in a state interested or fully elongated, motion light due to the expansion of oil is better than on the occurrence of extreme pressure for their expansion or cavitation oil trapped inside.
Storage and handling of oil
The proper handling and storage can secure the equipment. There is no way suggested a reduction in contamination, but it should be noted that none of the procedures that can be done if the contaminated fluid is inserted into the system. Purifier (refiners) to prevent entry of contaminants into the oil up to the time of delivery. It is important to be careful in preventing the entry of contaminants after delivery and during storage and handling.
Select the storage area clean and dry. Save and close the drum beside them to prevent the entry of dust contamination. The water above the drum will enter through the cover and into the oil drum. The water contained in the hydraulic oil will reduce the reliability and service life. Drums must be protected from the temperature changes suddenly and must be kept entirely. Before opening the drum, wipe the top of the drum with care so that the dirt does not fall into the oil.
Initial screening of oil will help clean oil consumption. Before disassembling the filler cap to add oil to the hydraulic system, used to clean the lid and filler nozzle using a clean lint-free cloth. Cover with a tight reservoir after filling. An important part of the preventive maintenance program is to keep the oil clean.
