Non-metal baler hydraulic system components introduction
The components of the hydraulic system of the non-metal baler include: power components, control components, actuator components, and auxiliary components. Horizontal non-metal baler hydraulic system power components are hydraulic oil pumps; control components are hydraulic valves to control hydraulic oil pressure, flow, direction; actuators are hydraulic cylinders, hydraulic motors; auxiliary components are pipe fittings, pressure gauges, accumulators, filters Oil and so on. The function of the power component of the non-metal baler hydraulic system is to convert the mechanical energy of the prime mover into the pressure energy of the liquid, which refers to the oil pump in the hydraulic system, which provides power to the entire hydraulic system. The hydraulic pump is generally constructed in the form of a gear pump, a vane pump and a plunger pump.
Control elements (ie various hydraulic valves) control and regulate the pressure, flow and direction of the liquid in the hydraulic system. Depending on the control function, hydraulic valves can be divided into pressure control valves, flow control valves and directional control valves. The pressure control valve is further divided into a flow valve (safety valve), a pressure reducing valve, a sequence valve, a pressure relay, etc.; the flow control valve includes a throttle valve, a regulating valve, a split flow collecting valve, etc.; the directional control valve includes a one-way valve, Hydraulic control check valve, shuttle valve, reversing valve, etc. According to different control methods, hydraulic valves can be divided into switch control valves, fixed value control valves and proportional control valves.
Actuating elements (such as hydraulic cylinders and hydraulic motors) convert the pressure energy of the liquid into mechanical energy, driving the load for linear reciprocating or swiveling motion.
Auxiliary components include fuel tank, oil filter, oil pipe and pipe joint, sealing ring, quick-change joint, high-pressure ball valve, hose assembly, pressure tap, pressure gauge, oil level oil temperature gauge, etc.
The reliability of the horizontal non-metallic baler hydraulic system depends to a large extent on the design of the seal of the hydraulic system of the non-metal baler and the selection of the seal. Due to the unreasonable selection of the seal structure in the design, the selection of the seal is not standardized. The compatibility of the hydraulic oil and the sealing material, the load condition, the ultimate pressure, the working speed, and the change of the ambient temperature are not considered in the design. These all directly or indirectly cause hydraulic system leakage to varying degrees. In addition, due to the dust and impurities in the design environment of the non-metal baler design, a suitable dust-proof seal should be selected in the design to prevent dust and other contaminants from entering the system to damage the seals and contaminate the oil, thereby causing leakage.
1. The design accuracy of non-metal balers should be reasonable. The geometric accuracy and roughness of the moving surface of the non-metallic baler should be ensured in the design of the non-metal baler. In the design, the strength of the joint is checked, and the design requirements of high precision and rationalization can ensure that the leakage of the non-metal baler is avoided.
