The accumulator is one of the main components of the hydraulic system, whose main function is to smooth the flow and prevent the impact on the circuit. All testing, troubleshooting, repair and accumulator charging services are carried out by Saman Sanat Pouya Company.
Various types of hydraulic storage can be categorized as follows:
1. Gaseous: the basic idea is creating pressure on the fluid with the help of a gas. Therefore, to follow safety rules, a non-flammable gas such as nitrogen is commonly used.
a. Piston model: in order to create a force to the fluid in accordance with thermodynamic rules and entering the fluid into the circuit, the nitrogen gas cylinder and piston system is used.
b. Bubble model: gas and fluid in those accumulators are separated by a rubber skin. In the initial installation and charging, the accumulator is filled with nitrogen gas and the gas enters the inside of the rubber to the desired pressure.
c. Diaphragm model: the model is similar to the bubble model, but the separation of fluid and gas is done by using a rubber diaphragm.
d. Single-section model: gas and fluid are not separated from each other.
2. Weight model: This type consists of a cylinder that is perpendicular to the head and is mounted above the weight, and therefore, due to its forces, it orbits the fluid. Because the weight force always enters the body, a constant pressure is introduced into the fluid during the whole piston movement, which is one of the benefits of this type. Due to the difficulty of installing common heavy weights, this category is rarely used in industry.
3. Spring model (bouncing): The energy required to drive fluid into orbit is provided by spring. When the fluid enters into the accumulator compartment, the spring is squeezed and, according to Hooke's law, it changes its size, and then it releases the fluid into the circuit when it is released. The springs which can make the required power are usually large. These accumulators are rarely used because of large sizes compared to other types of similar capacity size accumulators.
