Hangzhou Xingda ventilation equipment to undertake all types of tin ventilation engineering, ventilation engineering tin Hangzhou, Shaoxing tin ventilation engineering, fume purification project in Hangzhou, Hangzhou, engineering, installation and design of ventilation, fire smoke hotel kitchen project, Hangzhou, central air-conditioning duct installation and other train service. The company has experienced professional and technical personnel, specialized in various industrial and mining enterprises, hotels ventilation pipe installation, ventilation ducts schools, hospitals and other ventilation and exhaust gas treatment, waste dust collection of design and installation. Air conditioning (fresh air) unit fresh air inlet should be provided with electric air blower interlock to prevent freezing in winter because the temperature is too low and the heat exchanger, Riverside area plant exhaust, intake unit, before the water pipes (especially electric valve) bypass branch should be set up, to run before flushing pipes, service lines use; water dish must close watertight; heat exchangers shall be provided after freezing can access space. (3) When two cooling towers in parallel, intermediate drain pan is preferably provided a pressure equalization tube, the same as the diameter of the intake pipe, galvanized iron ventilation engineering company, located in the middle valve. Pump supply, is also located between the backwater best a connecting pipe, the middle set up check, otherwise the two towers runs prone to overflow a tower, a tower keep water phenomenon. Damping base (4) The master and other equipment must be good, and to ensure that the level degree within the permissible deviations, or prone to vibration or excessive noise phenomenon unit is running. 3.4 Duct Detection Equipment Co., Ltd. in Hangzhou Xingda undertake all types of ventilation Ventilation tin, tin ventilation engineering Hangzhou, Shaoxing tin ventilation engineering, fume purification project in Hangzhou, Hangzhou plant exhaust design, engineering, installation and design of ventilation Hangzhou, hotel fire kitchen row Smoke engineering, Hangzhou, central air-conditioning duct installation and other train services. The company has experienced professional and technical personnel, factory smoke window, specializing in various industrial and mining enterprises, hotels ventilation pipe installation, ventilation ducts schools, hospitals and other ventilation and exhaust gas treatment, waste dust collection of design and installation. After the duct system is installed, the system should be closely category test, the wind strength should be able to meet without cracking at the seams at 1.5 times the working pressure. Rectangular duct allows air leakage should meet the regulatory requirements. Tightness test under low pressure in the duct system process guaranteed under the premise of using leaked assay. When the test failed, the sampling rate should be required to do the air leakage test; tightness test pressure duct system after the light leakage inspection, use special air leakage air leakage tester to do the sampling; high pressure duct system tightness tests were performed amount of air leakage test to be done. Plant smoke window | Jianggan plant smoke | plant engineering supplied by Hangzhou Xingda exhaust ventilation equipment. Hangzhou Xingda ventilation equipment (www.tz1288.com/shop/index_6525.html) strong, credible, in Hangzhou, Zhejiang fan, ventilation equipment industry has accumulated a large number of loyal customers.
