What details should be paid attention to when cooling the ventilation duct Shenyang ventilation duct manufacturers use ventilation ducts to cool down the main stream of the factory workshop, so what details should be paid attention to when using ventilation ducts to cool down? 1. Ventilate and cool down. Because the sun shines on buildings, machinery, equipment, human body and other heat sources, the temperature of places requiring ventilation is higher than that of outdoor places. The negative pressure fan can quickly discharge the hot air in the room, so that the room temperature and the outside temperature are equal, and the temperature in the workshop will not rise. 2. Air flow takes away human body heat, air flow

What will happen if the exhaust hood of Shenyang ventilation duct is not the right model? 1. The investigation results show that most of the users can choose the correct exhaust hood type, but there are also some wrong exhaust hood types. For example, a push table saw generates wood dust when sawing. Because of the large particle size and high specific gravity of wood dust, the wood dust generated during the push table sawing will fall to the ground after moving a short distance along the sawing streamline. In general, the lower suction hood should be used to control the wood dust generated by the push table saw, but the upper suction hood is used in the design

How to fully ventilate the ventilation pipeline in Shenyang? Shenyang Ventilation Duct How to Fully Ventilate The ventilation duct is used to transport dusty airflow. It connects the dust hood, dust collector, electric fan and other components together. Whether the pipeline planning is reasonable directly affects the usefulness of the entire dedusting system. Therefore, Shenyang ventilation pipe manufacturers believe that they should sum up and consider various problems in pipeline planning to obtain more reasonable and useful solutions. During operation, the interface between Shenyang ventilation pipe, electric fan and air outlet will oscillate

How to quote for Shenyang Ventilation Engineering? The quotation of Shenyang Ventilation Engineering, regardless of material, is based on the length of the center line of the air duct in the construction drawing. It is calculated according to the open area of the air duct with different section shapes (circle, square, rectangular), and measured in square meters. For the manufacturing and installation of purification ventilation pipes and components, the calculation method of quantities is the same as that of general ventilation pipes, and the corresponding quota is used. However, the purification cost of components and devices shall be calculated, and 35% of the base price of the devices of the corresponding component sub item shall be taken as the purification cost, of which the labor cost shall account for 40%. For purification pipeline
