Connection of hydraulic system of tensile testing machine
Connection of hydraulic system of tensile testing machine
The hydraulic system is the power drive mechanism of the tensile testing machine. When the tensile testing machine is connected to the hydraulic system, we need to pay attention to the following connection matters of the hydraulic system of the tensile testing machine. Let us take a look at it in detail. One, dismantle each part For the strapping, clean the inside of the tubing with clean kerosene, especially the connection threads of each tubing. Two, check whether the gasket at the joint is intact, if it is damaged due to transportation, you should use the new gasket attached to the tensile testing machine to install it. , To prevent oil leakage under high pressure. Third, use a suitable wrench to connect each oil pipe, if it is a seamless copper pipe, connect the host, and rely on the movement of the console to adjust the spacing to connect the console end. Fourth, put the residual oil in the tank Remove the oil and remove the residue in the fuel tank. 5. Open the iron door of the hydraulic control box, you can see the wire mesh oil filter, and when the oil is filled, the oil filter is injected into the oil tank. The tensile testing machine usually uses hydraulic oil, and it should be used in summer. Use hydraulic oil with a higher viscosity, and use a hydraulic oil with a lower viscosity in winter. VI. Pay attention to the oil level when refueling the tensile testing machine. Too little oil, the testing machine cannot work normally, and too much oil will cause hydraulic oil Leak from the working cylinder port.
Hydraulic universal testing machines have very high accuracy requirements.
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.
In order to prevent accidents, safety protection devices are installed in the design of the testing machine.
