Installation Standards for Hydraulic Hose Fittings

2022-11-12

A hydraulic hose fitting is a rubber product consisting of polyethylene and a soft outer tube. Compared with rubber hose, it has the advantages of oil resistance, weather resistance, acid and alkali resistance and corrosion resistance. The inner layer of the joint is composed of imported superfine fiber and high-strength braided soft rubber. It has the characteristics of oil resistance, high temperature resistance, flame retardancy, good aging resistance, not brittle, no aging, good high and low temperature resistance, etc. During the welding application process of the hose joint, there must be no defects such as cracks and pores. When using, it must be noted that the sealing conditions must comply with the GB/T6138-2008 technical conditions for hydraulic joints used in pipeline engineering machinery; hose joints are used to connect two or more different joints for movement or to connect pipes and fluids; if damaged after use It cannot be resumed. That is to say, if it is found to be seriously damaged or needs to be reused after repair, it also needs to be reinstalled; it can be welded, used and maintained; it can also be selected without pressure requirements or use in certain areas.

1. When the pipeline leaks or corrodes during use, it cannot be replaced immediately, and a hose joint must be installed between two different joints.

       When a leak has been resolved, it cannot be replaced. When using a hose connector, its working pressure must comply with the regulations. The standard product model, sealing material and strength index that meet the regulations should be used during installation. The method used is a special form of joint. It is made of special molds and precision rubber sleeves. There are seals inside, and the inner and outer rubber hoses are connected to ensure the sealing performance of the pipeline connection. This kind of joint has the characteristics of oil resistance and high and low temperature resistance because it has the characteristics of oil resistance, high temperature resistance and corrosion resistance. It can also be used in some special spaces without pressure. It can be used in some occasions that require special connection. It can well solve the problem that its service performance is not long enough to cause damage but can be used normally; at the same time, it can also have an aesthetic effect. It is a more economical and convenient connection device, and can also be used as a mechanical device; its installation method It is relatively simple, that is, to fix it in a suitable position with bolts; it has good sealing.

2. When installing the hose joint, pay attention to the connection method and size, and pay attention to the construction and installation.

       When installing, check whether there are cracks, air holes and other defects in the connecting parts. If cracks are found, they must be repaired. And the connection quality should be checked regularly during use to ensure the service life. The corrugated compensator used in the hose joint can effectively compensate the deformation of the pipe, and at the same time protect the joint from external impact, so it will not be deformed or damaged, and will not affect the service life. The corrugated compensator adopts sealing materials and manufacturing processes to ensure its good sealing performance. The sealing performance is good, the service life is long, and the maintenance cost is reduced. The hose joint manufacturer said that some small details should not be ignored, otherwise it will affect the service life of the hose joint. Especially during use, if problems are found, they should be resolved in time. How to install the hose joint: First of all, it should be determined whether the pipeline interface is correct; in the pipeline, if there is leakage, it should be installed in the pipeline, and the hose joint should not be damaged by external force; if it is damaged, please reinstall it. This is to check the required pressure before installing the hose joint to ensure its normal use. There are several important steps in the installation process of the hose joint: placing the sealing material in the pipeline; tightening the mounting flange of the rubber hose and the soft hose joint and the fastening nut of the seal; tightening the fixing bolt on the seal; tightening the nut will It is tightened and the gasket is used to fasten the sealing ring on the sealing; the rubber strip is wrapped on the spring with tape; or the sealing tape is tightened on the rubber ring; if there is leakage, the pipeline should be closed in time and all gaps should be checked; during use , if there are air bubbles inside, it will cause pipeline leakage. Otherwise it will be unusable and continue to repair. Usually, when parts such as sealing rings and bolts need to be replaced, it is necessary to select a suitable length and use suitable tools to install them in place and ensure the normal operation of the equipment before installation. And the valve should be closed immediately after each opening of the pressure to prevent air leakage, and whether there is dust and other sundries in the surrounding space should be considered during installation; installation methods and precautions; please use special tools for operation; use safety measures when inspecting pipelines; If possible, the inspection method is as follows: install all hose joints in a proper position to prevent the pipe from being connected normally; use appropriate brackets around the pipe to provide a stable support for it to prevent the rubber seal from falling off and damage the hose joint; It should be noted that it cannot be disassembled; the sealing structure must be reliably fixed.
