High-pressure hose hidden precautions

First, choose a brand , quality assurance business , quality assurance, sales and service companies generally better manufacturing , high quality requirements .
Second, pay attention to the hydraulic fittings high-pressure hose assembly installation and operation. Not blindly cut production .Third, the high-pressure hose for industrial products, the use of units should be aware of their required product specifications. Blindly buy one of the factors also contributed to the quality problems .Fourth, as the user , but also pay attention to the high-pressure hose storage environment.

Metal hose selection

For a certain length and gauge metal hose, its ability to withstand stress and shock have certain limits, therefore, when used to choose according to the actual situation. Generally used with a nominal hydraulic hoses pipe same nominal diameter, length of the hose under the sink array of tanks, lateral displacement temperature deformation, misalignment, and other factors to produce an earthquake to determine. Corrugated metal hydraulic ferrules, nets and joint composed of three parts, bellows are made ​​of stainless steel, with good flexibility, small longitudinal rigidity and bending stiffness, can work within a radius of curvature of the nominal, with strong corrosion resistance and good temperature stability. Nets from the strengthening of the role of the metal hose with a larger carrying capacity. Therefore, the metal hose with shock, subjected to bending, absorb stress.

Overview of the hose

Hoses are divided into: stainless steel hose, metal hose, corrugated hose, plastic hoseCorrosion resistance of stainless steel hydraulic ferrule depends on the content of chromium, when added to the 10.5% of chromium, the atmospheric corrosion resistance of steel significantly increased, but the higher chromium content, while still being improved corrosion resistance, but obvious. The reason is that when the steel with a chromium alloying treatment, the type of change has become similar to the surface oxide formed on the surface of pure chromium oxide of the metal.Chromium-rich oxide protects the surface of this tightly adherent to prevent further oxidation. Such thin hydraulic fittings oxide layer, through which you can see the natural luster of stainless steel surfaces of stainless steel has a unique surface. Moreover, if the damaged surface, and atmospheric reactions exposed steel surface will self-repair, re-formation of this "passive film", continue to play a protective role.

Development of hydraulic hose assembly

After a few years of rapid development of reform and opening up , China's hydraulic hose assembly industry has made tremendous progress , their results were witnessed world , due to the development of Jic hydraulic fittingsassembly industry , the whole process of industrialization has also been driven up, get up vigor and vitality. Now, in the 21st century , especially after the party's 18 , China's economic development has entered a new phase, corresponding , for many industrial sectors and departments have also made ​​new demands. Therefore, as a hydraulic hose assembly industry , the need to establish a new development ideas, promote their own development and to adapt to the new era of development plans and ideas.First, companies should establish a people-oriented business ideas. Fully excavated talent, use of personnel , with talents for the development of enterprises to make a great contribution. For this reason , companies should be based on their actual situation , the construction of a mining standards and procedures of talent, and talent to make a different for different but appropriate arrangements to allow these people to give full play the initiative in different positions forhydraulic tube fitting industry to contribute their value.Second, enterprises should also be market-oriented, proactive , rather than passive waiting for the market ruling. With a lot of uncertainty on the market , these uncertainties , for the enterprise, is a potential threat , it will affect the interests and long-term development of enterprises. Therefore, enterprises should establish a set of internal hydraulic hose industry market response plans for a variety of problems that may arise , emergency preparedness , in order to achieve the purpose of being prepared .

use of the high-pressure hose size

When the high-pressure hose be withheld , will always produce withhold too tight or too loose phenomenon, and these phenomena often lead to adverse effects of high pressure hose . Today we say it is the size of the amount withheld would it have any effect on the high-pressure hose . We carried out by the following detailed understanding .Withhold the amount and rate of withholding high pressure hose and fittings assembly when the improper or joint structure and material , size selection is unreasonable, can lead to high pressure hose and fittings withholding too hydraulic hose assemblysor too loose will cause early damage to the joints .When assembled , if the withholding amount is too small, that is between the high pressure hose connector and cut through the loose , high pressure hose there may emerge in the role of oil in the early use from the joint ; If withholding is too large, then the connector and hose too hydraulic tube fitting , easily lead to hose inner being localized damage, cracks , directly into the high-pressure oil from the ruptured steel layer , and then he went to the wire along the gap between the spray coat tails , or has fled somewhere along the wire layer build up , so that the outer layer of plastic to produce drum kits and even rupture . Hoses and connectors in the assembly, if the withholding too fast, likely to cause damage to the plastic layer and the wire break, so that premature failure of the hose in use .The above information is very detailed description of the effect of the size of the amount withheld for the use of high-pressure hose produced , so we need considerable attention when using this withholding his dosage size is accurate, whether the mutation will produce high pressure hose , etc. problems should close attention.

Hydraulic hose assembly is the basis of hydraulic system components

Hydraulic hose assembly is the basis of hydraulic system components. Various hydraulic system is mainly used in construction machinery , metallurgy, mining machinery, and easy installation and removal of the . It is composed of high-pressure steel wire braided or twisted hydraulic hose assembly and steel fittings made ​​by special equipment withhold conduct hydraulic power transmission or conveying water, gas, oil pressure medium to ensure circulation of the liquid and transfer the liquid energy.
Hydraulic hoses need proper protection. Due to the complexity of hydraulic hose varieties , structural diversity, coupled with different conditions , so the length of life , not only on their quality , but also depends on the proper use and maintenance . So even if the product has high quality , if not properly used and maintained , will seriously affect the quality and longevity of its use , even a serious accident should not have occurred , causing damage to property . First of all, dedicated specifically to deal with . hydraulic hose assemblysand hose assembly can only be designed for transporting materials , other materials can not be used to send . Secondly , the use of the pressures within the . Hose and hose assembly should not be used in excess of the design working pressure ( including shock pressure ) . Third, the transportation of materials moderate temperature . Under hose and hose assembly conveyed medium temperature normal circumstances, should not exceed -40 ℃ - +120 ℃. Fourth, given the appropriate use of space hose , not bent. Hose and hose assembly should not be less than the minimum bend radius under the hose , to avoid bending or folding occurs near the pipe joints , otherwise it will impede hydraulic transmission and delivery of materials or damage to the hose assembly. Finally , keep the hose clean. Hose and hose assembly should be kept clean , inside should rinse ( especially acid output tubes, spray tubes, mortar tubes ) . To prevent foreign objects into the lumen , hinder the transport fluid , damage to the device .

Many factors will affect the use of hose assembly

Many factors will affect the use of the hose assembly. The first is the size of the hose. Inner diameter of hydraulic hose assemblysto the right, if it is too small, will affect efficiency. If the inside diameter is too large, will affect the overall system performance of the play. Therefore, it is important to select the appropriate inner diameter. Second, hydraulic hoses will also affect the temperature range of use. If the hydraulic hose working environment temperature exceeds the specified range, then the hydraulic hose pressure capacity will thus be greatly reduced. Experts suggest that if the high or low temperature working environment, should be put on the hydraulic hose jacket. In addition to the above two factors, the use of hydraulic hose assembly Hose working pressure is also affected by the impact stress and fatigue life, impact bending radius and chemical compatibility and other factors.
Hydraulic hose assembly in our lives is very wide, in the mining industry, agriculture and industrial sectors have a lot of use. It is transmitted through water and gas or oil substance hydraulic power to ensure adequate fluid energy during operation.
