What is a hydraulic cylinder?
Hydraulic cylinder is a mechanical actuator, which can convert the fluid pressure into mechanical force, and is suitable for construction, aerospace, manufacturing and other fields that require special force such as pushing and lifting.
What are hydraulic cyilnders used for?
Hydraulic cylinders are mainly used in places where heavy equipment is needed, like civil engineering, construction, aerospace, agriculture and marine industries.
What are the advantages of hydraulic cylinders?
Hydraulic cylinders can be adjusted to many extreme conditions, and they do not suffer from power loss due to the distance limitation from the power source. And they can also have automatic overload protection, variable speed control, etc.
What is hydraulic cylinder made of?
The material selection of hydraulic cylinder is diverse, and each has its own merits. The most commonly used materials are carbon steel, stainless steel and a couple of alloys.
How to measure hydraulic cylinder?
First prepare the tools for measurement, such as thread gauge, tape measure caliper, etc. Next, you should check the hydraulic cylinder brand, and then measure the piston diameter, rod diameter, rod extension and retraction length, thread type, hose port size and diameter, etc.
What are the components of hydraulic cylinder?
Hydraulic cylinder parts mainly with these kinds of: cylinder head, cylinder barrel, cylinder bottom, piston, rod and some seals, etc.
How many types of hydraulic cylinders?
There are several types of hydraulic cylinders, which are single and double acting cylinders, telescopic cylinders and tandem hydraulic cylinders.
How to bleed hydraulic cylilnders?
Different hydraulic cylinders are bleed in different ways, but most of them need to comply with the following points. Choose the right tool and location, discharge the gas in the order of pipeline from far to near, make sure the hydraulic tank is full state so that the gas can be discharged, and finally check several times after the hydraulic pump tank exhaust is finished to make sure the gas is completely discharged.
Why is hydraulic cylinder cushioned?
Hydraulic cylinder cushioning is to slower the speed of the hydraulic cylinder. The aim is to reduce the damage to the piston, extend the service life of the hydraulic cylinder, and also to reduce a certain amount of noise pollution.
How hydraulic cylinders work?
The principle of operation of a cylinder is the Casper principle. The hydraulic cylinder piston, with the help of pressurized liquid, moves in the barrel and generates the appropriate power to push the hydraulic cylinder to work.
