O princípio de funcionamento do cilindro hidráulico

Homemade hydraulic press machine,A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and makes linear reciprocating motion (or oscillating motion).

First let us learn the 5 of most basic components.

1、cylinder barrel and cylinder cap

2、Piston and piston rod

3、Sealing device

4、Buffering device

5、Exhaust device

Homemade hydraulic press machine,According to its structure, hydraulic cylinders can be divided into piston, plunger, multi-stage telescopic sleeve, rack and pinion, etc. The working principle of each kind is similar. Take manual jacks as an example (jack is actually a simple cylinder), the hydraulic oil through a one-way valve into the cylinder by the manual booster culm (hydraulic manual pump), and cannot backflow because of the one-way valve, which forcing the cylinder rod up, and then continue to get more oil into the cylinder to work in this way. If we need to let it down, just open the hydraulic valve to let the hydraulic oil return to the tank. This is the simplest working principle, and the others are all based on this. Then take the cylinder of manual handling truck as an example, which is putting the pressure on the handle to make the hydraulic oil into the one-way valve and then into the cylinder, it rises because of the one-way valve cannot flow back. The piston rod rises due to the hydraulic oil pressure, and the hydraulic oil continuously into the cylinder, the piston rod will keep rising. This is why we see the car is rising when we put pressure on the handle of the manual handling truck. The rising of the car body is due to the rising piston rod, and the piston rod is due to non-return hydraulic oil pressure, which can be down when we open the hydraulic valve to let it back to the tank and lower the height of the car.

Piston type hydraulic cylinder working principle

  Homemade hydraulic press machine,Hydraulic cylinder as the implementation of components is essentially a kind of energy gathering and transformation equipment. Application: when the hydraulic cylinder extends, the lower hydraulic machine cavity introduces emulsified oil or gear oil, and the other upper hydraulic machine cavity discharges to promote the piston rod to the guiding set orientation fitness movement; when the hydraulic cylinder retrieves, the upper hydraulic machine cavity introduces emulsified oil or gear oil, and the other lower hydraulic machine cavity discharges.

    Homemade hydraulic press machine,The basic principle is hydraulic cylinder will be keyed into the working pressure energy of the fluid into the piston rod uniform linear motion of mechanical kinetic energy. To put it bluntly, the keyed hydraulic energy is the total flow and working pressure of the keyed fluid, and the output mechanical kinetic energy is the rate v (m/s) and driving force f. All such main parameters are dependent on the work of the capacity shift, so that the hydraulic cylinder is a capacity type of implementation components.
