What is a hydraulic cylinder?
The hydraulic cylinder creates linear movement and strength by means of pressure hydraulic fluid. Industrial machines powered by hydraulic rollers are able to create metals or other materials with very high force with a relatively low supply of high pressure fluid. Heavy equipment
, such as an excavator, relies on the power of hydraulic fluid. The operator easily controls the pressure hydraulic fluid by means of a control valve connected to the distributor hoses and tubes. The solenoid valve is the type of valve most commonly used with a hydraulic cylinder because it has a reputation as safety and reliability. The valves not only control the release of the fluid in the hydraulic cylinder, but often also mix gases and liquids. When the brake pedal is depressing, the pedal is pushing the piston in the main hydraulic cylinder and there is a slave piston every round we cooperate to stop the car.
Hydraulic seals are crucial in relation to the safe functioning of the hydraulic cylinder. The industry that uses the heavy equipmentThe automotive industry, the aerospace industry, the government, the oil and the gas, relies on the improvement of the hydraulic seal technology. The Challenger Space shuttle explosion in 1986 was credited mainly by a non -functional hydraulic seal caused by low temperatures that stiffened the inner material of the seal, preventing the correct sealing.
worn hydraulic seal also represents safety concerns, but can often be prevented by a hydraulic cylinder with a smooth inner surface. The outer surface of the hydraulic cylinder is usually designed from aluminum, steel, cast iron or bronze. The cylinder covers hold the piston rod and can be designed to match each particular cylinder.
The simplest hydraulic systems consist of the pistons and a tube filled with liquid. Pistons used in hydraulic systems are produced in one, two or three pieces depending onon the speed and strength required by the machine. One piece of heavy construction machines uses up to eight hydraulic cylinders that can need up to 100 gallons of oil.
Water hydraulic systems use water as a fluid for hydraulic cylinder rather than oil. Although water is cheaper than oil, as well as non -term, low water viscosity and poor lubricating properties require the system designed exclusively for water hydraulics.
