Industrial chillers are common equipment in industrial production. A standard chiller mainly includes main components such as compressor, condenser, filter, expansion valve, capillary, evaporator, and water pump. Water pumps play an important role in chillers. The importance of a water pump is like that of the heart to the human body. So for chille...

2024-02-2124820This article proposes a new concept of using energy driven molecular gears. Using visible light as the energy source, HTI actively promotes different gear transmission processes at the nanoscale.Unlike hot gear transmission, light gear transmission is the dominant movement within the molecular framework. Meanwhile, the conversion of 180 ° doubl...
2024-02-2027810Generally, the following aspects should be considered for inspection:1) Whether the motor torque is large enough and whether it can drive the load, we generally recommend users to choose a motor with a torque 50% to 100% greater than the actual need when selecting, because stepper motors cannot run under load, even in an instant, it will cause step...
2024-02-2021910As is well known, the chiller unit, also known as the refrigeration unit, mainly cools and cools the equipment. With the compressor as the core, heat is transferred from the low-temperature evaporator end to the high-temperature condenser end through a reasonable matching of the evaporator, condenser, and corresponding throttling capillaries, there...
2024-02-20211101、 Precautions for starting a handheld laser welding machinePower on sequence: turn on the air switch → wait for three to five seconds for the water machine to start, then turn on the emergency stop and key switch → wait for the touch screen to enter the interface, set the welding parameters → click on the air valve to test whether t...
2024-02-19265101. It is not impossible to drill holes on the solder pad. If you are willing to spend money on small holes, the laser hole and plugging process should be fine;a. For BGA pads with a spacing of less than or equal to 0.5mm, they must be very dense and holes must be drilled on the pads; The difficulty and cost of PCB plate making process have increase...
2024-02-1920210As is well known, ultraviolet laser chillers are one of the many classifications of chillers, widely used in the laser production and processing industry, such as various types of lasers and laser equipment with various powers. However, if we want the use of UV laser chillers to become more long-lasting, we must carefully maintain the chiller.Mai...
2024-02-1923810I saw a device without any sensors, and the servo can return to the origin very accurately. The servo is from Yaskawa, and the encoder is incremental. The servo motor rotates in a circular motion, sometimes it cannot rotate less than one turn, and once the action is completed, it returns to the origin. Sometimes it may take several rotations to ret...
2024-02-18289201. Microcontroller systemUsing a microcontroller system to achieve motion control has a lower cost, but the development difficulty is high and the cycle is long. This solution is suitable for users with large product batches, simple control system functions, and experience in microcontroller development.2. Professional motion control PLCMan...
2024-02-18253101、 Servo systemA servo system refers to an automatic control system that utilizes the action of a component (such as a control rod) to reach or approach a predetermined state, and can compare the desired state (desired value) with the actual state, adjusting the control components according to their differences (sometimes the rate of change of this...
2024-02-1828410Researchers at the University of Alto have adopted a new approach to create a metamaterial that exceeds the technological scope that has emerged so far. Unlike natural materials, metamaterials and metasurfaces can be customized to have specific electromagnetic properties, which means scientists can create materials with the characteristics required...
2024-02-1720610The Dark Knights of Gotham City possess a series of impressive technological wonders, but the superhero scientists at the National Renewable Energy Laboratory of the US Department of Energy possess their own cutting-edge capabilities.A recent battery manufacturing project, affectionately known as Batman, has developed a novel laser patterned chem...
2024-02-1723310When William Frieden Dempton, a PhD candidate in mechanical engineering, planned to carefully study how laser powder bed melting process parameters affect microstructure, he never imagined discovering manufacturing defects that had previously been overlooked in PBF-LB additive manufacturing.Shrinkage porosity is a common defect in metal castings,...
2024-02-1521810Pixel Voltaic, a subsidiary of the University of Porto, has launched a laser system for sealing glass and fiberglass perovskite photovoltaic modules, with a maximum size of 30 cm x 30 cm. The company's technology roadmap is to increase production capacity to accommodate larger equipment areas of up to 1 square meter and modify processes to operate ...
