The operation steps of the impact sample cryostat, the method of using the cryostat—Jinan Liangong
As a professional manufacturer of testing equipment, the CDW series compressor refrigeration shock sample cryograph produced by it can refrigerate any temperature from room temperature to -100 ℃, and the temperature control accuracy is as high as 0.5 ℃. Because of its superior temperature control accuracy, wide cooling range and good durability, it has won unanimous praise from many users. The specific operation steps of the impact sample cryogenic tank are as follows, please read it carefully.
1. Add an appropriate amount of cooling medium to the cooling tank, such as absolute ethanol or other antifreeze
2. Put the clean samples in the sample basket in order and put them into the cooling tank of the impact sample cryostat.
3. After confirming that the power supply is under the specified voltage and grounding safety, and all parts of the equipment are normally turned on; switch.
4. The temperature control meter is powered on, and press the temperature setting key (set) to enter the temperature setting state. Press the plus, minus and move keys to set the temperature. After setting the required temperature, press the set button to return to normal operation and memorize the parameter value.
5. Turn on the stirring; switch to check whether the cooling medium in the cooling tank of the low-temperature tank has good fluidity.
6, finally turn on the refrigeration; switch.
7. When the medium in the cooling tank is close to the set temperature, the constant temperature heating device works and the indicator light flashes; when the set temperature is reached, the automatic alarm device sounds, and the thermostat starts to record the time and displays the constant temperature time , The operator can turn off the alarm when hearing the news; switch, when the thermostat displays the required constant temperature time, the sample can be taken out for impact test.
8. After the test, turn off the stirring; switch, refrigeration; switch and power supply; switch.
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.
