Elbow machine is an important equipment for processing metal pipes, and the hydraulic system, as one of its core components, plays a vital role. The hydraulic system realizes the functions of the elbow machine through the transfer and control of the liquid, such as bending, clamping, moving and so on. This article will deeply discuss the working principle, composition, working process and maintenance of the hydraulic system of the elbow machine, so as to help readers understand this key component more comprehensively.
First, the working principle of hydraulic system
Hydraulic system is a kind of power transmission system that uses liquid transfer, and its working principle is based on PASCAL's law, that is, in a closed container, the pressure of the liquid is evenly distributed in all parts of the container. In the hydraulic system of the elbow machine, the hydraulic pump extracts the liquid from the liquid storage tank and transmits it to the hydraulic cylinder or hydraulic motor through the pipeline, so as to control the various executive parts of the elbow machine.
The working process of the hydraulic system can be simply described as: when the hydraulic pump starts, the liquid is pumped into the pump body, forming a certain pressure, and then transmitted through the pipeline to the hydraulic cylinder or hydraulic motor, so that it performs the corresponding action to complete the processing of the metal pipeline. In this process, the hydraulic system realizes the precise control of the elbow machine by controlling the flow and pressure of the liquid.
Second, the composition of the hydraulic system
The hydraulic system of elbow machine is mainly composed of hydraulic pump, hydraulic cylinder, hydraulic motor, hydraulic valve, oil tank, oil pipe, oil filter and so on. The hydraulic pump is responsible for drawing out from the tank and providing a certain pressure; The hydraulic cylinder drives the piston movement through the liquid pressure to realize the bending function of the elbow machine; The hydraulic motor converts the liquid into mechanical energy to drive the other parts of the elbow machine.
The hydraulic valve plays the role of regulating and controlling the liquid flow in the hydraulic system, opening or closing the hydraulic channel according to the need, so as to achieve the operation of the elbow machine; The tank is used to store liquid and maintain the stability of the system; The oil pipe and oil filter play the role of transporting liquid and filtering impurities to ensure the normal operation of the hydraulic system.
Third, the working process of the hydraulic system
The working process of the hydraulic system of the elbow machine can be divided into four stages: hydraulic pump working stage, hydraulic cylinder working stage, hydraulic motor working stage and hydraulic valve control stage. In the working stage of the hydraulic pump, the hydraulic pump starts, the liquid is pumped into the pump body, and a certain pressure is generated; In the working stage of the hydraulic cylinder, the liquid is transported to the hydraulic cylinder to drive the piston movement and complete the bending of the metal pipe; In the working stage of the hydraulic motor, the liquid is converted into mechanical energy to drive other parts of the elbow. Finally, in the hydraulic valve control stage, the hydraulic valve controls the flow and pressure of the liquid according to the operator's instructions to achieve accurate control of the elbow machine.
4. Maintenance of hydraulic system
To ensure the normal operation of the hydraulic system of the elbow machine, regular maintenance work must be carried out. First of all, it is necessary to regularly check the various components of the hydraulic system, including hydraulic pumps, hydraulic cylinders, hydraulic motors, etc., to ensure that they work normally; Secondly, the liquid in the hydraulic system should be replaced regularly, and the fuel tank and oil pipe should be cleaned to prevent impurities from causing damage to the system; In addition, the working state of the hydraulic valve should be checked regularly to ensure that it is flexible and reliable; Finally, pay attention to the temperature and pressure of the hydraulic system to avoid overheating and overload, affecting the normal operation of the system.
In short, as one of the core components of the elbow machine, the hydraulic system plays an important role. By understanding the working principle, composition, working process and maintenance of the hydraulic system, we can better grasp the working principle of the elbow machine, improve the use efficiency and life of the equipment, and provide a better guarantee for the production operation. It is hoped that this article can help readers to understand the hydraulic system of elbow machine more comprehensively, and provide reference and guidance for practitioners in related industries.
