Elasto Proxy supplies five types of rubber hoses to the heavy equipment and transportation industry.
- 充气气体
- Coolant hoses
- Fuel hoses
- Air intake hoses
- Heater hoses
以下部分详细描述了每种类型的橡胶软管。有关其他信息，包括avideoand downloadable guide, please see ourCustom Silicone Connectors页。
Charge Air Hoses
充气气体are used to connect the charge cooler inlet to a vehicle’s turbocharger or intercooler. They’re also used to connect the charge cooler inlet to the engine manifold. Charge air-cooler hoses, as these rubber products are known, must prevent the loss of air pressure even under the most extreme engine conditions. They have both a hot side and a cool side, each with product specifications.
增压空气软管热的一面是红色或黑色in color and manufactured through wrapping, a process that also requires material preparation, vulcanizing, and cutting steps. Materials of construction include FKM/VMQ and AEM in 1, 2, or 4 ply. Unlike the liner, the middle and cover section of the hose may have an aramid fabric reinforcement. Working temperatures range from -40°C to around 250°C.
The cool side of a charge air-cooler hose is blue in color and produced through wrapping and/or extrusion. The range of working temperatures is narrower than on the hot side and spans -40°C to 170°C. The relative pressure, burst pressure at high temperature, inner diameter, and wall thickness are the same on both sides of the air cooler hose. Polyester fabric can be used to reinforce the middle and cover section.
冷却剂软管
Coolant hoses are category of products that include upper and lower radiator hoses, heater hoses, and bypass hoses. They are designed to withstand heat, vibration, pressure, and chemicals while conducting coolant from the water pump to the heater. For more demanding applications, wrapped VMQ is the material of choice. For less demanding applications, lower-cost extruded EPDM is used instead.
Wrapped VMQ coolant hoses can have a 1-ply liner that is red in color. They can also have a 3-5 ply middle and cover section that’s blue in color and reinforced with polyester fabric. Extruded EPDM coolant hoses are usually black in color with a polyester reinforcement. Compared to EPDM coolant hoses, VMQ coolant hoses have a broader range of working temperatures and a higher burst pressure.
燃料软管
燃料软管在整个车辆的加油系统中使用，该系统包括燃料供应管，燃料返回线和燃料压力调节器。通常，这些橡胶软管从NBR / PVC，FKM / AEM或FKM / ECO挤出。对于所有这些材料，最低工作温度为-40°C。对于NBR / PVC，140℃，FKM / ECO为140℃，170°C的最高工作温度为170℃/ AEM。
进气软管
Air intake hoses send a controlled stream of air to the engine. They need to maintain proper pressure and be free from debris that can degrade engine performance. These rubber hoses are usually made of EPDM, CM, or CR and do not have reinforcements. They have both a clean side and a dirty side; however, they lack positive pressure. Compression and injection molding are used to manufacture these hoses.
Heater Hoses
Heater hoses are used to transfer excess heat from the engine to the heater core, the small radiator that provides heat to the cabin. They are smaller than other types of rubber hoses but must still withstand coolant chemicals. Depending on the application, either VMQ or EPDM may be used. Both materials have a minimum working temperature of 40°C; however, VMQ has a higher working temperature (170°C) than EPDM (125°C).
