The safety, practicality, economy and reliability of the hydraulic transmission system are all very important. Therefore, considering the taboos of choice is mainly considered from these four aspects.
The maximum pressure of hydrostatic drive systems and components need to be limited, that is, they need to be used below the rated pressure. In addition to the hydraulic power source of the pressure-compensated variable pump, one or more hydraulic ball valves should be installed on the system to limit the pressure of all parts of the hydraulic system. In particular, the relief valve should be installed where the hydraulic cylinder has a rod cavity, which is used to prevent the pressure increase caused by the difference in piston area from exceeding the rated pressure limit of the hydraulic cylinder.
No redundant circuit can be set in the hydraulic power transmission system. The control function of the hydraulic system, including the control accuracy, can only be selected and designed within the possible range of existing components, and excessive control design may be redundant.
In addition to the simple and practical design of the hydraulic power transmission system and circuit, the selection of hydraulic components should also be based on the premise of satisfying the function, and the relatively low-priced components should be selected.
The connection form between hydraulic components is very important. In addition to the two-way cartridge MHA hydraulic valves, which is the first choice for high-pressure and large-flow hydraulic systems.
The brand of hydraulic components such as hydraulic hose fitting is also very important and should generally be specified in the contract between the supplier and the buyer. It is best to choose a simple connection form and easy-to-purchase hydraulic components, which can shorten the construction period of the hydraulic system, help reduce costs and improve economic benefits.
Under the premise of ensuring the completion of the required functions, the simpler the hydrostatic drive transmission system, the better. The more complex the hydraulic circuit design, the higher the failure rate may be. While the simpler the hydraulic system and circuit, the higher the reliability.
The hydraulic circuit function should be clear and single, otherwise safety and reliability may be affected. The functional circuits in the hydraulic system cannot interfere with each other. The hydraulic pump may reverse due to the mutual interference of the circuits or the action of external loads. The actuators may also move or rotate beyond the preset due to the mutual interference of the circuits or the action of external loads.
Except for special hydraulic devices or hydraulic machines, it is forbidden to use pipelines such as industrial hose pipe or circuits to directly connect the hydraulic power source and the actuators across the reversing valve, because this may cause the hydraulic actuators to become uncontrollable.
The above are the taboos when choosing the hydraulic system, but in general, the choice of hydraulic system depends on our actual needs and budget. If you want to purchase hydraulic system components such as industrial hoses and fittings, you can consider choosing Jazzy Industrial.
