La válvula piloto hidráulica es una válvula auxiliar utilizada para manipular el mecanismo de control en otras válvulas o componentes, y adopta la transmisión hidráulica. La presión hidráulica es un término en la industria mecánica y la industria electromecánica. La presión hidráulica puede usarse como un método de transmisión de potencia para convertirse en una transmisión hidráulica. Las válvulas piloto son mecanismos de control que controlan la apertura (cierre) de otras válvulas. Convierte la energía hidráulica en energía mecánica para controlar otras válvulas y el flujo de control.
The role of the hydraulic pilot generally speaking, auxiliary valves, auxiliary distributors, and wheel loaders with hydraulic pilots have faster hydraulic oil transmission and stable pressure. When the wheel loader stops, the solenoid valve hydraulic oil will not flow back, and the boom will not retract freely. Because the hydraulic pilot is the pilot oil circuit, its oil is sent to the control spool through the handle or other control valves to push the spool to move, so that the high-pressure oil reaches the actuator through the gap after the spool moves. When the wheel loader stops, the control valve automatically cuts off the power, and then the control ends. After the end, the hydraulic oil will not return and the boom will not retract. On the contrary, for a wheel loader without hydraulic pilot, the pressure is unstable. When the wheel loader stops, the hydraulic oil will flow back and the boom will retract.Generally, we recommend configuring a wheel loader with rated load of 2 tons or more to make it work more efficiently. It is not recommended to install the wheel loader below 2 tons, because the attachment will be too sensitive and unstable.
