(Summary description)Correct Assembly Installation

Install the hose in a corred way is very important,it will affict the hose’s appearance and cost a lot while it is too long, but if the hose is too short, it cannot flex while being crushed. Both too long and too short can bleak down the hose. So pay more attention to the following guides before you install the assembly:

1.Hose should not be twisted. Hose is weakened when installed in twisted position. Also pressure in twisted hose tends to loosen fitting connections. Design so that machine motion produces bending rather that twisting.
2.Since hose may change in lenth from +2% to -4% under the surge of high pressure, provide sufficient slack for expansion and contraction.
3.Don’t use any clamps at the inflexion so as it can move freely.
4.Choose right angle fittings to avoid too small bending radius and excess force.                                                                                         
5.Hose bending radius should be as big as possible when it is in motion.       
6.Reduce friction:avoid hose touching the object directly or farway from the object.
Technical Instruction

There are many factors which can affict the usage condition of hose assembly, use the hose assembly and hose fittings in a correct way can ensure its reliability and economical efficiency. These factors are following:

1.Hose Dimension
  The selection of hose inside diameter must be correctly made,if the hose inside diometer is too small. It will speed up the medium in the pipeline

2.Working Pressure
  The dynamic working pressure in this catalog refers to the allowable maximum pressure in condition of continuously working. According to the safety modulus of hydraulic hose ruled by international stangard, we recommend that the working pressure is one forth of the minimum blast pressures.

3.Impact Pressure&Fatigue Life-span
   After determining the maximum system pressure for a hydraulic system hose selection can be made. For the hydraulic system’s pressure always be dynamic, there often appears an impact pressure the maximun impact pressure is much higher than the maximum system pressure.To be luckily, there is a overfall valve in every hydraulic system, so high impact pressure cannot affect the fatigue lifespan seriously. As for hydraulic system whose impact pressure appears very frequently, we advise you choose the special hydraulic hose which is able to endure the high impact pressure.

4.Temperature Range
  User must ensure that the temperature is in an allowable range of hose,if exceeding this range, the life-span of hose will be shorten, and the copacity to endure pressure will get down if the working condition temperature keep too high or too low in a long time, we advice you use the hose spring guard.

5.Chemical Compatibility
   If use special hydraulic medium, user should ensure the material of hose inner side and cover, the hose fittings and O-ring can compatiable. With the special hydraulic medium.

6.Bending Radius
   Pay more attention to its minimun benging radius when install the hose assembly, if the bending radius is smaller than the minimum one. The capacity of enduring pressure will get down and the life-span of hose will be shortened.

7.Friction
   We advised you use a soring guard if the hose assembly is always in the condition of touching and making friction with hard object.
