There are two main types of waterproof test requirements for automotive electrical equipment products in China's automotive industry standards: 1. The product installed under the hood or exposed should be subjected to IPX4 splash-proof test for 10 minutes: swing tube method (bend radius R=400mm, center spacing of adjacent nozzles is 50mm, 180° arc on both sides of the center of the swing tube) There are nozzles in the section, each nozzle has a diameter of 0.4mm, a water flow rate of 10L/min, and a water pressure of 80KPa.) 2, products installed in the cab and passenger compartment and luggage compartment need to withstand 10min IPX3 anti-leaching test: swing tube method (bend radius R = 1000mm, the center spacing of two adjacent nozzles is 50mm, the center of the swing tube is on both sides There are nozzles in each 60° arc segment, each nozzle has a diameter of 0.4mm, a water flow rate of 10L/min, and a water pressure of 80KPa.) Burner is an important part of furnace.The combustion of fuel, the direction and shape of the flame, the discharge of the exhaust gas and the distribution in the climbing chamber are all related to the structure of the furnace.In addition, the heating of charge, melting time and fuel consumption are directly affected by the burners structure, so the correct choice of burners size and diameter of the maintenance work is of great significance.Most of our burners are made of stainless iron, which is strong, durable and makes the product beautiful in appearance.Furnace vent is not blocked, and can provide sufficient oxygen for combustion. Under the condition of ensuring pure gas and smooth transportation, the flame is blue, which is the normal standard flame color, and no harmful gas of carbon dioxide.
