The extremely complex research object is called a system, that is, an organic whole with specific functions combined by several components of interaction and interdependence, and this system is also a component of a larger system to which it belongs.
N95 is not a specific product name, as long as it meets the N95 standard, and the product passed the NIOSH review can be called the N95 mask, which can filter particles with aerodynamic diameter of 0.24 ± 0.6μm (physical diameter 0.075µm ± 0.020µm) Over 95%.
The belt conveyor adds a telescopic mechanism to the ordinary belt conveyor, so that the belt conveyor can freely expand and contract in the length direction. Users can adjust the buttons according to their own requirements, and control the length of the telescopic belt conveyor at any time.
Reliability measures generally have three types: reliability, failure-free rate, and failure rate. The study of reliability issues was developed during the Second World War to deal with the unreliability of electronic products. The research on reliability design used in machinery began in the 1960s and was first applied to military and aerospace industries, and then gradually expanded to civil industries.
Mathematics has existed and developed for thousands of years. He originated from practice, but also rooted in human reason. Mathematics has always been effective in the journey of human understanding of the world, and it must be effective in the future, because no learning is more rigorous, rational, and reliable than mathematics.
N95 semi-automatic rotary edge banding machine, model parameters can be edited, equipment drawings are a full set of drawings, including engineering drawings.
“Reliability of products is designed, produced and managed”, but practice has proved that the reliability of products designed first. Reliability design has a significant impact on the inherent of the product.
The equipment uses ultrasonic welding to fuse the elastic band to the outside of the mask body, which is a process after the external ear mask is produced.
During the work of the mechanical designer, every small point must be considered very clearly. As a rigorous worker, you must understand those complicated mechanical knowledge points.
As a designer, you must master a basic design software, and 3D modeling is also essential today. So, which software do you use most? How do you feel about using it?
DC53 is a high-strength and toughness general-purpose cold-working die steel. It is an improved version of SKD11 by Japan Datong Co., Ltd. DC53 completely overcomes the shortcomings of SKD11 high-temperature tempering hardness and toughness. It will completely replace SKD11 in high-precision molds.
The structure is generally composed of multiple layers of nonwoven materials. The common structure is the S structure (that is, spunbond-meltblown-spunbond). The woven material has a good filtering effect.
The product architecture diagram is usually used in more complex product projects and is one of the indispensable documents when designing complex products. In this article, the author also introduces you to the process and key points of drawing the product architecture diagram, and hopes to inspire you.
It belongs to a horizontal medium-sized packaging machine. Its working principle is that the packaging roll film enters the former through the packaging film drive roller and is formed. After the packaged object is fed into the former by the feeding conveyor, it is longitudinally sealed and transversely sealed. , And then output by the discharge output machine.
Fully automatic sealing and cutting shrink packaging machine is a highly automated equipment.This product is widely used in medicine, food and beverage and household industries. The application of shrinking machine can greatly reduce the materials and labor costs of medium box packaging, which has important economic significance. , Heat shrink packaging machine accounted for several …
