Hydraulic equipments make use of hydraulic power to carry out work. These hydraulic machines use pressurized hydraulic fluid to do work and are used for various applications. Heavy construction equipment is an obvious example. In such a scenario, the hydraulic fluid is supplied to the different hydraulic cylinders and pistons through the main hydraulic lines and gets pressurized as per the physical resistance present.
There are many types of hydraulic equipments available in the market and each type has its own specific function. The two most widely used types of hydraulic fluid pumps are rotary and linear pumps. Rotary pumps are generally used to pump water and other liquids via a pipe. Once the fluid is pumped into the pipe, the force of the water makes the valve closes so that the fluid remains inside. If the pipe is unventilated and if the air is thin, the flow will be small and the pump may have to operate at high pressure to maintain the flow.
A typical rotary pump has two working pistons and a connecting rod. The piston moves back and forth and the connecting rod connects the rotor to the housing https://hydro-tek.vn/san-pham/gioang-phot-thuy-luc/. When the piston moves, the rotor also moves. As the hydraulic fluid passes through the system, it causes the connecting rod to move and consequently the hydraulic fluid in the storage cylinder. The two fluids move against each other in a back and forth fashion, thereby allowing the hydraulic system to maintain a constant rate of hydraulic flow. Most of these hydraulic equipments operate with the assistance of a small pump which is operated by the engineer.
The hydraulic system works on large scales in construction sites and requires large capacity pumps. On smaller scales, these hydraulic systems work with much smaller displacement. The smallest hydraulic pump can handle up to 15 HP, the largest being one hundred and twenty-eight HP. Since most hydraulic systems work on positive displacement, the hydraulic fluid is not allowed to flow backwards.
There are certain disadvantages of using hydraulic fluid. The most obvious is that, because there is no physical way to prevent the fluid from flowing backward, the pump will be working at full capacity constantly. Another disadvantage is that when using these types of equipment, you cannot stop the flow just because you do not like the level of fluid in the storage cylinder. This type of system uses pressurized hydraulic fluid and when this fluid is exposed to atmospheric pressure, there is a high risk of leakage. The hydraulic system works only when the fluid in storage is in motion.
To conclude, hydraulic systems are very important to any construction site or operation. Before choosing a particular hydraulic system, it is important to check the equipments’ usability and efficiency. The price is also a very important factor, but it should never come in replacement of safety. Safety should always be given first priority. Choosing the right type of hydraulic system ensures that you will not have any problem with your project.
