Application of wear-resistant polyurethane steel wire hose on road sweeper
Road sweeper is a new type of high-efficiency sweeping equipment integrating road sweeping, garbage recycling and transportation. Simply put, it is a special vehicle chassis that is modified with a road sweeping function. In addition to the chassis engine, the vehicle is also equipped with a secondary engine. The four sweeping brushes are driven by a hydraulic motor, with a fan and a wear-resistant suction hose. , Trash cans, water tanks and other supporting equipment. This brand-new model can complete ground cleaning, road dent cleaning, road dent cleaning, and watering of the ground after cleaning, and is suitable for cleaning operations in various climates and different dry roads.
my country's road sweeper industry has experienced decades of development. The products have developed from a single pure sweeping type to a variety of types. Product performance and product quality have rapidly improved, especially after the reform and opening up, through the import of key outsourcing parts. The performance and reliability of road sweeper products are greatly improved. However, there is still a certain gap between the level of road sweepers in my country and developed countries abroad, especially in terms of product reliability. In order to improve the level of road sweepers in my country as soon as possible, narrow the gap with the level of road sweepers in advanced countries, and meet the requirements of my country's environmental sanitation departments for road sweeping operations, road sweeper manufacturers should choose a suitable road sweeper research direction. With the development and progress of society, we are no longer satisfied with vacuum cleaners in a pure sense, and will put forward more requirements from the aspects of multi-function, environmental protection, and economy. The market calls for vacuum cleaners that can meet various needs.
Polyurethane steel wire hose is one of the important components of road sweeper. According to the operating environment of the sweeper, its matching dust suction hose must meet the following requirements: high wear resistance, free expansion and contraction, and discharge of static electricity. Sweeper operations require static electricity due to friction, chemical resistance, and long service life. Dust suction hose, wear-resistant suction tube, wear-resistant hose, polyurethane steel wire hose is a high-performance wear-resistant suction tube specially developed and manufactured for the resistance of sweepers.
Vacuum hose, wear-resistant vacuum tube, wear-resistant hose, polyurethane steel wire hose, polyether polyurethane, with high adhesion galvanized steel wire spiral reinforcement. The inner wall is smooth to ensure that the material flows smoothly in the tube. Vacuum hoses, wear-resistant hoses and polyurethane steel wire hoses of different specifications have an inner diameter of 0.9 mm. Resistant to mold and hydrolysis. Has excellent ozone and weather resistance. Food-grade polyurethane steel wire hose complies with EU 2002/72/CE food-grade standards and US FDA food-grade standards 21CFR177.1680 and 177.2600. The hose is non-toxic, odorless, and halogen-free, and meets the requirements of the RoSH environmental protection directive. The grounding of the spiral steel wire can discharge static electricity, which meets the requirements of TRB S 2153, and the flame retardancy meets the UL94 V0 standard. Usually used for suction occasions, especially suitable for abrasive solids, such as dust, powder, fibers, debris and granular; gaseous and liquid media, industrial dust removal and suction, industrial vacuum cleaners, paper or fabric fiber suction, As an anti-wear protection tube.
Properties: high wear protection (6 times higher abrasion resistance than most rubber materials, 5 times higher than soft PVC), smooth interior, optimized flow characteristics, stretchable; high tensile strength, And tear strength; good mineral oil resistance and chemical resistance; good UV and ozone resistance and low temperature flexibility, small bending radius, not easy to kink, no softener and halogen; no gas and liquid leakage, Flame-retardant meets UL94-HB standard and RoHS regulations. It can discharge static electricity through spiral wire grounding.
Structure: Spiral elastic steel wire is firmly implanted into the wall of the tube to optimize the external fluidity, and the wall thickness is about 0.9 mm
Material: Pipe wall: (polyether-polyurethane, polyester-polyurethane) optional, spiral wire: elastic steel wire.
Temperature resistance range: about -40°C to +100°C, up to +125°C in a short time
