A hydraulic hose is a high pressure hose made of synthetic rubber, thermoplastic or Teflon
Transfers fluid for power transmission in hydraulic machines
The development of flexible hydraulic hoses further paved the way for the development of a wide range of new high-powered machines based on hydraulic technology
Hydraulic hoses, Compressed are made of plastic They are responsible for powering the machines
. These days, hydraulic systems in various industries such as the construction industry, Shipbuilding, road construction, automobile manufacturing
, agriculture and… Has been used and is of great importance. In hydraulic systems, pumps convert mechanical energy into compressed fluid power
. In the next step, the hydraulic hoses will direct this fluid to different parts of the device
. Wired hydraulic hose inner layer The material of the inner layer must be compatible with the fluid, as it is in direct contact with it
. Therefore, in case of fluid change, pay attention to its compatibility with the material of the inner layer
. The inner layer should not be mac or porous
. Fluid temperature affects the inner layer And withstands operating temperatures between -41 and +100 degrees. The function of the inner layer is to seal the hose connections
. Wire reinforced layer The woven layer of wire makes the hose resistant to internal pressures
. This layer gives a special mechanical resistance to the hose
. In addition to holding the two ends of the hose in place, it provides electrical conduction
. Exterior protective cover The outer cover protects the hose against the following factors
: Non-conductivity of electricity Abrasion resistant, Flame, against ozone And UV rays
, Against corrosion Types of external protective coatings Elastomeric smooth coating, elastomeric wrapped
, woven from fibers, woven from steel Standard hydraulic hose The following table shows the SAE hydraulic hose standard
: Type of fluid passing pressure range SAE standard number Petroleum condensate Chemical oils Water-based fluids Working temperature
