It is suitable for hydraulic transmission of construction machinery, lifting, transportation machinery and mining machinery. Hydraulic transmission principle - oil is used as working medium, Chengde Oil cylinder The movement is transmitted through the change of sealing volume, and the power is transmitted through the pressure inside the oil. 1. Power part - converts mechanical energy of prime mover into pressure energy (hydraulic energy) of oil. For example: hydraulic pump. 2. Executive part - converts the oil pressure energy input by the hydraulic pump into the mechanical energy driving the working mechanism. For example: hydraulic cylinder, hydraulic motor. 3. Control part - used to control and adjust the oil pressure Chengde Oil cylinder Manufacturer Flow rate and flow direction. For example: pressure control valve, flow control valve.
Compared with mechanical transmission, hydraulic cylinder transmission is a new transmission form. Hydraulic transmission has a history of more than 200 years since the birth of hydraulic press, but hydraulic transmission has been going on for many years. Especially after the 1960s, with the development of atomic energy science, space and hydraulic technology, Chengde Oil cylinder It permeates all fields of the national economy, including agricultural machinery, automobiles, light textile, shipbuilding, petroleum, aviation and machine tool industries, Chengde Oil cylinder Manufacturer Hydraulic technology lists some application examples of hydraulic and pneumatic transmission.
1. There are many factors that cause this problem. First, measure the pressure of the main system to see whether the pressure of the main system in the pressure holding state is consistent with the initial setting. Check the hydraulic oil and suction oil filter before measuring the pressure, Chengde Oil cylinder Replace or clean it. Secondly, check the main overflow valve of the reversing control multi way valve to see if it is damaged or blocked by foreign matters, Chengde Oil cylinder Manufacturer Clean it. If your pump is a gear pump, the problem should be minor in general. 2. Next, let's look at the traffic problem.
The hydraulic cylinder is the actuating element that converts hydraulic energy into mechanical energy in the hydraulic system. The faults can be basically summarized as hydraulic cylinder misoperation Chengde Oil cylinder Manufacturer It is unable to push the load and the piston slips or crawls. It is not uncommon for hydraulic cylinder failure to cause equipment shutdown. Therefore, Chengde Oil cylinder Attention should be paid to the fault diagnosis, use and maintenance of hydraulic cylinder. The main reason for excessive wear of piston seals is that the speed control valve is improperly adjusted, resulting in excessive back pressure, improper installation of seals or contamination of hydraulic oil. Secondly, foreign matters enter during assembly and the quality of sealing materials is poor.
Hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or swing motion). It is simple in structure and reliable in operation. When it is used to realize reciprocating movement, the reducer can be avoided, Chengde Oil cylinder And there is no transmission clearance, smooth movement, so it is widely used in various mechanical hydraulic systems. Output force of the hydraulic cylinder is proportional to effective area of the piston and pressure difference on both sides; The hydraulic cylinder basically consists of cylinder barrel, cylinder head Chengde Oil cylinder Manufacturer The piston and piston rod, sealing device, buffer device and exhaust device are composed.
