What are the characteristics of the electro-hydraulic servo universal testing machine cylinder?
The electro-hydraulic servo universal testing machine is a widely used hydraulic universal testing machine. The oil cylinder is composed of five parts: a spherical support rod, a pressure cap, a working piston, a spherical support and a working oil cylinder. The oil cylinder of the microcomputer-controlled electro-hydraulic servo universal testing machine adopts a gap-sealed grinding cylinder, which is precisely ground by a grinder. When the pressure oil enters the working oil cylinder from the oil port and acts on the lower end surface of the working piston, it pushes the working piston upward. The working oil cylinder and the working piston have a good fit and are sealed by the gap between them. The inner wall of the working oil cylinder of the WE type universal testing machine is the guiding surface for the movement of the working piston. When the other oil port is connected to the oil return pipe, the working piston moves downward by its own weight. The hydraulic cylinder of the electro-hydraulic servo universal testing machine has the following three characteristics: 1. The end surface of the working piston is the working surface that bears the pressure oil, and the power is transmitted through the piston itself. 2. There is a large empty knife part in the lower half of the cylinder body, so the processing is more convenient. 3. The working piston is equipped with a spherical support rod, which is always under pressure during the working stroke, which can realize the centering effect. For more information, please refer to the official website of Chenda, focusing on the development and production of testing machines for more than ten years, mainly engaged in hydraulic universal testing machines, electronic universal testing machines, friction and wear testing, compression testing machines, tensile testing machines, torsion testing machines, steel bars For bending testing machines, sleeper static load testing machines, etc., new and old customers are welcome to visit the factory for inspection and purchase!

Hydraulic universal testing machines have very high accuracy requirements.
The hydraulic system is the power drive mechanism of the tensile testing machine.
The specific application of the electronic universal testing machine in the automobile manufacturing process: The electronic universal testing machine needs to be used for automobile parts.
Wave soldering refers to the molten solder (lead-tin alloy), sprayed by electric pump or electromagnetic pump into the solder wave required by the design, can also be formed by injecting nitrogen into the solder pool, so that it is pre-loaded The printed board of the component realizes the soft soldering of the mechanical and electrical connection between the solder end or the pin of the component and the pad of the printed board through the solder wave.
The frequency converter is a power control equipment that uses frequency conversion technology and microelectronics technology to control AC motors by changing the frequency of the motor's working power supply.
Electronic universal testing machine is a necessary equipment to control the quality of products.
The calibration operation of the electronic universal testing machine is still relatively unfamiliar to friends who use it for the first time.
Selective wave soldering defects and their prevention.
Testing machine, broadly speaking, is an instrument that verifies the quality or performance of a product or material according to the design requirements before it is put into use.
The tensile force is not an accurate value after being measured by the testing machine, and subsequent calculations are required to get the desired value.
