Upon entering the Changshan Hengsheng branch, there was a fresh and modern feeling. In a large, spacious and bright large-scale workshop, rows of new looms are lined up neatly, and they are “very high-speed†and look spectacular. And the temperature in the workshop is clean and tidy. “In the past, I walked to the old textile workshop and stuck cotton wool on the body and hair. I almost could not see cotton hair flying here.†“The production facilities here are really advanced and the automation level is really high!†A representative from other places visited and praised.
Some of the delegates took a look at the "New Product Experimental Machine" sign hanging on the looms. Some of them also asked the staff: "Why is there such a signage" and "How many new products are there?" According to the explainer of Changshan shares, 600 sets of internationally advanced air-jet looms have been put into production for more than two years. The production efficiency is very high. New products are often born. About 30% of the machines are new fabrics and special products. And are produced according to the order.
From the line to the bright and spacious finishing workshop, the reporter saw two special rows of new fabric showcases set up here, and various new fabrics made the representatives from all over the province “open their eyesâ€. "Air conditioning fiber home textile fabrics, according to the environment to adjust the temperature, improve the comfort of the human body; Fei Si fabrics, with a silky luster, soft touch, natural antibacterial, there is "second skin"; Tencel fabrics, with natural Comfortable, feels like silky soft; cotton active printed fabric, clear lines, smooth, moisture-absorbent breathable; (3rd edition)
Key technical transformation The municipal party committee and the municipal government attached great importance to technological transformation work and successively issued the Ten Opinions on Encouraging the Accelerated Development of Industrial Enterprises, Several Policy Measures to Support the Industrial Economy in Eastern Plain Counties (Cities) to Realize a Leap-forward Development, and Shijiazhuang City. Supporting documents such as the Implementing Rules for Several Policy Measures to Achieve Leapfrog Development in the Industrial Economy in Eastern Plain Counties (Cities) and the Implementation Opinions on Accelerating the Implementation of Technological Transformation of Industrial Enterprises, and setting up a special technical reform fund of 100 million yuan for municipal level The "Twelfth Five-Year Industrial Development Plan for Shijiazhuang City" was compiled. At the same time, the city also actively sought national, provincial special funds for technical reform, and effectively promoted the rapid development of the city's leading industries.

Peristaltic pump
There are a few plaster sprayers that have a peristaltic pump (a tube squeezed by rollers) which also requires compressed air to produce a spray. These types of plaster sprayer can also spray textured coatings with particle sizes up to about 3mm diameter, providing that they are not solvent based.
Piston pump
Newer types of plaster sprayer have a piston pump, which has sufficient pressure to spray smooth (untextured) plaster without compressed air. Full airless pumps are sometimes used to spray smooth plaster, although they are not ideal as the flow rate is too low for volume projects; however, they can be used to spray solvent-based plasters.
Air operated piston type supply pumps can put out as much as 27 gpm. Like the Graco Bulldog 10:1 at about 9 gpm and the Lincoln Pile driver 5:1 at about 27 gpm. These flow-rates are calculated at a maximum of 120 cfm air supply. Material supply hoses are medium pressure at about 600 psi. These pumps are material supply pumps only and additional air is required at the Spray Gun to propel the material to the surface. These guns are usually an internal mixture type guns where the material and air exits the gun together.
