How To Clean The Hydraulic Hose?

The cleaning of hydraulic hose is very important, the hydraulic hose is equivalent to the human body in the industry. Once the blood vessels appear unclean, then people will be sick, the truth is the same.

Hydraulic hose is not clean will cause hydraulic oil pollution, the contaminated hydraulic oil will block the hydraulic components, affecting the normal movement of components. The hydraulic hose does not clean will produce abnormal vibration and noise, this is because of the hydraulic pump oil is not smooth. In addition, the hydraulic hose does not clean lead to impurities into the hydraulic pump to speed up the wear of parts, with increased clearance, causing internal leakage, greatly reducing the life of the hydraulic system. It also creates cleaning difficulties. In addition will damage a lot of tight components, causing damage to components, increase maintenance costs. If the hydraulic hose is dirty, it will cause the "illness" of the hydraulic system. According to statistics show that the hydraulic hose is not clean problems caused by the hydraulic system fault accounted for 60% of the proportion.

Fault analysis of Hydraulic hose: improper use, unreasonable system design and unqualified hose manufacturing. If the use of hydraulic hose in the use of improper will have an impact on the pipe, the following we will analyze this problem:

Firstly, the characteristics of the tubing are analyzed. Hose is divided into rubber pipes and plastic pipes, plastic pipes are cheap, easy to install, but poor carrying capacity, easy to aging, only applicable to the return tubing or relief tubing; rubber hose divided into high-pressure hose and low pressure hose two, high-pressure hose generally by the outer plastic layer, steel wire reinforced layer, the middle of the glue layer and the inner layer of the four components. The inner adhesive layer is directly contacted with the hydraulic oil and is usually made of synthetic rubber.

The carrying capacity of the hose depends on the reinforcement layer, which is the skeleton of the hose, usually woven or wound with wire. Most of the medium and high pressure steel wire braid as skeleton, high pressure, ultra-high pressure use steel wire winding skeleton. Outer plastic layer is generally used to wear-resistant, good corrosion-resistant rubber made to ensure that the strengthening layer is not mechanical damage, chemical corrosion, damp rust, low pressure hose to weave cotton, twine instead of braided steel wire, generally for low-pressure oil pipeline. The hose fault is generally manifested in the following four aspects: the failure of the outer rubber layer, the failure of the inner rubber layer, the failure of the reinforcement layer, the fault at the rupture port.
