Shanghai Textile Machinery Factory, formerly known as Shanghai No. 1 Machinery Factory, has long been a key player in the textile industry, specializing in the production of essential spinning and combing machinery such as draw frames, strip machines, combing machines, and other pre-spinning equipment. Over the years, the factory has continuously evolved, adapting to technological advancements and market demands. Recently, the factory introduced the CJ40S cotton comber, a groundbreaking digital servo multi-axis drive system developed independently by the Shanghai Textile Machinery General Factory. This innovation has already been successfully tested at the factory's experimental base, drawing significant attention from both domestic and international experts and industry peers. As part of the Pacific Electromechanical Group, this new model represents a major milestone in electrical automation for the textile sector. Unlike traditional combing machines that rely on mechanical systems driven by a main motor, the CJ40S utilizes advanced electronic cam technology, multi-axis synchronization, and bus control. These features enable precise control over the combing process, allowing adjustments to the separation motion curve and effective output length based on the specific type of yarn being processed. The machine also improves the coordination between the nipper plate and the detaching roller, ensuring better performance even with varying fiber qualities. Under the leadership of the Pacific Electromechanical Group, the factory has spent nearly half a century refining its combing technology through continuous research, collaboration with universities, and close partnerships with spinning enterprises. By integrating computer technology, digitization, and networking, they have developed a highly automated, intelligent, and digitalized cotton combing machine. This new generation of equipment replaces traditional mechanical cams and planetary gear systems with servo controllers and motors, offering greater precision, durability, and flexibility. The CJ40S uses an electronic cam that can store thousands of data points and multiple curves, allowing for quick and easy switching during operation. The system is equipped with a PCC controller, a user-friendly interface, a mainframe frequency converter, two closed-loop inverters, and encoders, enabling four-axis synchronous operation with high accuracy and stable performance. Additionally, the use of industrial bus control technology ensures fast data exchange between the control and drive units, making it easy for operators to adjust separation curves and speed ratios in just seconds. The machine also includes an Ethernet interface for seamless communication with higher-level systems, supporting centralized control and management of the entire production line. This level of integration not only enhances efficiency but also allows for quicker responses to changing market demands. The CJ40S is a product of the latest design concepts from the Shanghai Textile Machinery General Factory. It offers a simpler structure, lower energy consumption, and produces more uniform cotton web without breaks or irregularities. This leads to reduced raw material waste and improved product quality, with CV% values increasing by approximately 20%. Moreover, the ability to combine different lengths of cotton fibers makes it easier for spinning companies to adapt to market fluctuations. The CJ40S has already received a utility model patent, and an invention patent has been announced. The product has also been submitted as part of the national "Eleventh Five-Year Plan" 863 Program Major Project Proposal, highlighting its significance in the field of textile machinery.

Evaporator

Semi-welded plate evaporator has wide plate gaps, wide channel openings and laser welding, which enable them to perform vacuum and low pressure evaporation processes in both water-based and organic-containing systems.

Evaporator can be considered the point of heat capture in a refrigeration system and provides the cooling effect required for any particular application.There are almost as many different types of evaporators as there are applications of heat exchanger. However,evaporators are divided in to two categories such as (i)direct cooler evaporators that cool air that,in turn,cools the product and(ii) indirect cooler evaporators that cool a liquid such as brine solution that, in turn, cools the product. Normally, the proper evaporator comes with the system. However, there may be an occasion when designing a system, so one will need to determine the requirements and select the proper evaporator from a manufacturer's catalog or manual.

In practice,the following evaporators are commonly used for cooling,refrigerating,freezing,and air conditioning applications:•liquid coolers,•air coolers, and/or gas coolers.

Shell and tube type heat exchangers are the more common form of evaporation units for water cooling and chilling applications.
