Hello! The four kinds of cylinders of the car crane generally refer to the telescopic cylinder of the boom, the luffing cylinder of the boom, the horizontal telescopic cylinder of the outrigger and the vertical cylinder of the outrigger.
Tie rod hydraulic cylinder use
Tie rod hydraulic cylinder, compact structure, light weight, installation forms and easy to change, easy to install and dismantle; fittings and maintenance is also convenient, but the tie rod cylinder general working pressure is relatively low, is not very suitable for high-pressure occasions, in the high-pressure pressure is easy to destabilize. All generally not used in engineering machinery. Tie rod cylinder, is the most widely used type of cylinder, mainly used in die-casting machines, injection molding machines, molds, machine tools and other equipment.
Please ask: what is the material of the tie rod of the hydraulic cylinder? Where can I buy it?
Generally it is 45 gauge steel, just polished. It's best to buy it from the manufacturer, usually those places that sell electric motors, cylinders
Do you need to add oil to this kind of cylinder? Add what oil is good
Tie rod cylinder and solenoid valve to be refueled, add ordinary lubricating oil can be.
Because the rubber ring of the solenoid valve is oil-resistant, as for aging, it is bound to age, because it also has a service life. Tie rod cylinder is a kind of tie rod cylinder, such as SCSG series Yadek cylinder. The advantage of the tie rod cylinder is that the load carrying capacity is stronger than the non-tie rod type, and there is not much difference in the specific use.
Precautions for the use of cylinders:
1, air quality requirements
Use clean, dry, compressed air. The air shall not contain organic solvents, synthetic oils, salts, corrosive gases, etc., in order to prevent bad operation of cylinders and valves. Before installation, the connection pipe should be fully blown and cleaned, do not bring dust, debris, sealing bag pieces and other impurities into the cylinder and valve.
2, the requirements of the use of the environment
In the dust, water droplets, oil droplets, rod side should be equipped with telescopic protective cover. When the retractable protective cover can not be used, the cylinder with a strong dustproof ring or waterproof cylinder should be used. If the ambient and medium temperature of the cylinder exceeds -10～60℃ when using the magnetic switch, anti-freezing or heat-resistant measures should be taken.
In a strong magnetic field environment, automatic switching cylinders with strong magnetic field resistance should be used. Standard cylinders should not be used in corrosive fog, or in the fog where air bubbles appear in the seal.
3, cylinder lubrication
Cylinders used for oil lubrication should be equipped with an appropriate flow rate of oil mist. Do not give the cylinder oil lubrication, because the cylinder is pre-greased, can be used for a long time. This cylinder can also be used for oil draining, but once oiled, it cannot be stopped. When using turbine oil no. 1 for oiling, do not use oil, spindle oil, etc. to avoid double expansion of the NBR seals.
