Welcome to the official website of Guangdong Junying Hydraulic Technology Co., Ltd
There is actually a lot to learn about hydraulic knowledge, and everything needs to start from the basics. Today, we will mainly talk about the basic knowledge of hydraulic motor to everyone, hoping that everyone can have a better understanding of it. The deeper level of Ningbo Telems will also continue to explain it to everyone in the later stage.
Firstly, the classification of hydraulic components:
1. Hydraulic pump that converts mechanical energy into liquid (mainly oil) energy (mainly pressure energy)
2. Hydraulic control valve for regulating and controlling pressure energy
3. Hydraulic actuators that convert pressure energy into mechanical energy (hydraulic motors, hydraulic cylinders, hydraulic swing motors)
4. Hydraulic accessories necessary for transmitting pressure energy and adjusting the liquid itself
The characteristics of hydraulic technology:
The basic function of hydraulic circuits lies in the easy control of energy transfer in the form of liquid pressure energy.
From the perspective of energy transfer, hydraulic technology is roughly in the middle position between mechanical energy transfer and electrical energy transfer.
From the perspective of transmission characteristics, mechanical transmission and hydraulic transmission devices can be said to have fixed characteristics. On the contrary, hydraulic transmission devices and electrical transmission devices are the same and have the characteristics of continuously variable speed devices. In addition to constant power, they are also easy to achieve constant speed and torque characteristics.
The characteristics of hydraulic technology can generally be summarized as follows:
(1) Easy to perform stepless speed change, with a wide range of speed changes, that is, the force and torque can be easily adjusted over a wide range;
(2) Good control performance, which means that force, speed, position, etc. can be controlled correctly with a high response speed. In addition, it has good adaptability to other control methods such as electrical and mechanical systems, especially when combined with electrical signal processing, which can achieve excellent response characteristics;
(3) Reliable action and good operational performance;
(4) Moderate flexibility in structure and characteristics;
(5) Standard components can be used to construct circuits that achieve any complex function.
The reason for these characteristics is that volumetric components are used as capacity converters for hydraulic pumps and actuators, and lubricating oil (hydraulic oil) is used as the working medium. The general drawbacks of hydraulic technology are also related to hydraulic oil. These drawbacks can be summarized as follows:
(1) Oil leakage;
(2) In situations where special precision control is required, contamination of hydraulic oil has a negative impact on the characteristics of components and devices. That is to say, the management of hydraulic oil has a significant impact on reliability and the lifespan of components.
The purpose of hydraulic technology:
The characteristics of hydraulic technology are suitable for the automation, high performance, large capacity, small volume, light weight, and other requirements of various machinery and equipment. So although it is a relatively new branch of technology, it is widely used in the transmission mechanism of active power, the operation mechanism of auxiliary machinery, or the automation control mechanism of work.
