Every hydraulic power system must have a hydraulic cylinder, unless it’s used to power an hydraulic motor. The cylinder is responsible for converting fluid pressure into a lateral force. When pressurized hydraulic fluid is allowed to get into the cylinder, the fluid pushes the piston rod forward with great force. In a tipper truck, the piston, usually stretches out, lifting the trailer to an almost upright position, which empties the contents in the process. In the return sequence, the weight of the trailer simply pushes the piston to its initial position. Hydraulic cylinders Brisbane residents should know, come in a variety of sizes. They also have a wide range of uses, which is almost unlimited.
Types of Hydraulic Cylinders
Tipper trucks and hydraulic cranes have telescopic hydraulic cylinders, which have several sleeves that stretch out when the hydraulic fluid is pumped into the cylinder. Hydraulic lifts also have this type of cylinder.
Single-acting cylinders are the most popular in the industry. They are also the oldest. The piston rod inside the cylinder only moves in one direction, and can be returned by a powerful spring or the weight of the load being pushed or lifted in the forward stroke. This is also the simplest type of cylinder.
Double acting cylinders are also popular. As the name suggests, the cylinder has powered forward and return strokes. The cylinder has two fluid inlets. In the first stroke, the fluid pushes the cylinder in one direction. In the return stroke, the fluid pushes the piston in the other direction. These cylinders are incredibly popular in heavy earth-moving machines.
Hydraulic cylinders can develop a number of problems. First, the oil seals around the piston can get damaged, and cause fluid leakage and loss of power. Secondly, the piston can get bent when subjected to excessive forces. The inlet and outlet of the cylinder can also get damaged and cause fluid leakages. Whatever the problem, it is important you hire the best mechanical engineering firm to carry out the necessary repairs. The ideal firm should have technicians with a lot of experience with the type of cylinder you have. They should also be able to fabricate new parts if necessary.
If a new cylinder is needed, be sure to check the specifications of the new cylinder, in terms of the length of the stroke as well as the maximum pressure and force it can sustain. That said, you should consider shopping online as there are many manufacturers and dealers with an online presence, so you can easily compare prices before making the final decision.
