Product Description
The rubber suction and discharge hose has an inner rubber layer, multiple layers of cloth or cord and spiral steel wire are used as the reinforcement layer, and the outer rubber layer is determined according to the use of the pipe. These materials provide resistance against the abrasion and chemical attack from the transported mud or slurry
Outer Cover: Anti-aging and Abrasion Resistant Synthetic Rubber (SBR or NR)
Reinforcement Layer: High Strength Synthetic Textile Cords or Steel Wire Helix
Inner Tube: Anti-aging and Abrasion Resistant Synthetic Rubber
Δ When installing large-diameter suction and discharge hoses, the following points should be noted:
1. Determine the installation position and direction, and place the hose in the desired location for use.
2. Use appropriate tools (such as wrenches, pliers, etc.) to secure the rubber hose to the corresponding connector.
3. Check if the hose is secure and ensure that it does not twist or bend.
4. Connect the interface between the rubber hose and the equipment, paying attention to aligning the interface correctly.
5. Turn on the device and check if the hose is working properly. If there are any abnormalities, they should be dealt with promptly.
ΔThe function of large-diameter suction and discharge hose
The function of large-diameter suction and discharge hoses is to suck or discharge liquids or gases. It is usually made of pressure resistant and corrosion-resistant materials, with a large diameter and length, capable of withstanding flow. Large caliber suction and discharge rubber hoses are widely used in industries, agriculture, construction, and other fields, such as the inlet and outlet pipelines of water pumps, compressors, cleaning machines, and other equipment.
