Several Discussions on AA's Pressurized Air Supply System for Construction Machinery

AA Discussion on Construction Machinery Pressurized Air Supply System In civil building design, when there is no natural smoke exhaust condition, the places where mechanical pressure air supply is needed are: fire elevator shaft, smoke prevention stairwell, front room , Use an antechamber, evacuation walkways, safe passages, etc. With regard to the design of the mechanical pressurized air supply system, the industry's main implementation specifications are "High-rise Civil Building Design Fire Prevention Code" (GB50045-95) [1] (2005 Edition) (hereinafter referred to as "high regulation") and "architectural design fire protection specification “(GB50016-2006)[2( )”(hereinafter referred to as “Building Regulations”) and corresponding local standards and specifications, such as: “Technical Regulations for Smoke Prevention and Control of Buildings” (DGJ08-88-2006)[3]. Due to the large number of employees, and the understanding of the above norms and standards will inevitably be biased and disagreement, so that the engineering design practices are different. Without reasonable analysis and understanding of the relevant provisions of the code, the design of some pressurized air supply systems may lead to irrational type selection, insufficient air flow, and may even present a certain degree of hidden dangers. Foshan Delike Measurement & Control Instrument Co., Ltd. is a domestic company. Earlier specializing in the production of positive pressure air supply system before the room with floor pressure controller professional manufacturers. "Delik" "DLIKE" is our product brand. Our company is committed to providing all kinds of positive pressure air supply system differential pressure controllers and all kinds of pressure transmitters of medium height and precision type, and differential pressure transmission. , liquid level transmitters and other products. Our products have been used by customers for many years and have been highly praised by customers.

In order to meet the needs of the market and the majority of users, we have introduced the new DLK4520 and DLK4521 differential pressure controllers for positive pressure air supply systems. Welcome to inquire
