So how does this new type of sprinkler keep warm? What is its principle? Here we have detailed the working principle of this insulated sprinkler.
The tank installed on the chassis, the motor pump device is connected to the external power source through a three-phase harness, the water inlet of the motor pump device is connected to the outlet of the tank through the pipeline, the outlet of the tank body and the inlet of the motor pump device The pipeline between the nozzles is provided with a valve, and a water inlet is arranged above the tank body. The utility model has the advantages of compact structure, low cost, strong adaptability of the whole vehicle, safety and reliability, and simple operation, and is suitable for short distances between cities. Used for transportation.
Insulation material details:
One is that rock wool is made of selected basalt or diabase as the main raw material, melted at high temperature, and made by injection and other methods. Rock wool is filled with a certain amount of adhesives, dust-proof oil, water-repellent agent, and then processed into various rock wool products with various uses through solidification, cutting, and veneering. Rock wool and its products are characterized by light weight, low thermal conductivity, good sound absorption, non-combustion, good insulation properties, and strong chemical stability. The density is 80~250kg/m3, and the thermal conductivity is 0.04w/(mk). Around, the working temperature is -268 degrees to 700 degrees, but in the car is easy to sink to the bottom of the accumulation of the bottom of the skeleton to form a void affect the insulation effect. In addition, the insulating skin is not tightly sealed and leaks water, and rock wool is prone to absorb water and affect the heat preservation effect.
Another kind of insulation material is rigid polyurethane foam, using polyether and polyisocyanate as main raw materials, and then adding flame retardant, foam stabilizer and foaming agent. A microcellular foam, its thermal conductivity is generally around 0.02w/mk. Use temperature -100 degrees to 100 degrees. This material can prevent sedimentation and water absorption and other effects of insulation.
Insulation sprinklers fully support the masses against cold, where users in Guizhou, Hunan and other places can order 5,000 yuan in discount. My company produces Dongfeng, Futian and a series of 2 to 30 tons models for users to choose.
