What is the reason for the large temperature fluctuations in the low temperature tank (low temperature instrument) of the impact sample?
The impact sample cryostat, also known as the impact test cryostat, constant temperature cryostat, etc., is a refrigeration device for cooling and heat preservation of the sample in the metal low-temperature impact test. The CDW series impact cryostat is easy to operate and has high working efficiency. However, no device can guarantee zero failure forever. After the device has been used for many years, if the temperature fluctuation becomes larger and exceeds the original temperature range, how to operate?
Based on experience, the following reasons and solutions are summarized for your reference:
1. Too little ethanol in the tank. In this case, you need to add alcohol again.
2. The stirring failed to work normally. It is necessary to check whether the stirring is turned on. If the circuit is normal, the stirring motor needs to be replaced.
3. The PID parameters of the temperature control meter are incorrect. In this case, self-tuning needs to be re-tuned. If not, you can contact the manufacturer at any time and let the manufacturer's staff assist in the setting.
If you have purchase requirements for low-temperature baths for impact samples, please feel free to contact 400-623-6667 for consultation. Our professional service personnel will provide you with professional and efficient service and support.
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.
