Rubber Hose Installation Skills

Dongying Guangyou Rubber Co.,Ltd | Updated: Jul 04, 2017


Rubber hose before installation check: Before installation, the rubber hose must be carefully checked. You must check the left and right rubber hose structure, size, type and length, to ensure correct, the other need to check whether the rubber hose is clean, whether the plug, with or without blister, Rubber Water Hose outer layer is delaminated and other visible defects.

Pipeline arrangement: Pipeline arrangement should be noted: a. Installed with less than the required minimum bending radius rubber hose, will significantly shorten the life of rubber hose. B. Once the rubber hose assembly is damaged, the leaked stool will not touch the hot surface, fire and spark.

Rubber hose protection: In many applications, it may be necessary to fix the rubber hose, attach the protective sleeve or guide, to avoid the rubber hose by unnecessary twists and turns, the impact of pressure, Rubber Water Hose or contact with other mechanical parts wear.

Correct connection: Rubber hose is properly installed so that the rubber hose connector is connected to the oil path and does not cause twisting or torque on the rubber hose due to assembly, use, and so on. It is necessary to avoid damage to the rubber hose, such as tensile load, Rubber Water Hose lateral load, kink, inflection and potential wear.

System inspection: After installation, you should first let go into the system of air, the system pressure to the maximum working pressure, test system function is leaked. Personnel should be kept away from potentially dangerous areas during the trial.

Rubber hose maintenance: even if the correct selection and installation, if not sustained maintenance, rubber hose life will be significantly reduced. Rubber Water Hose The maintenance frequency should be determined according to the severity of the working condition of the rubber hose. The contents of the maintenance shall include at least the following items:

8.1 Visual inspection Rubber hose:

It is found that any of the following conditions must immediately replace the rubber hose:

A) Rubber hose leaks

B) rubber hose hardening, cracking, charred

C) rubber hose winding, broken, flattened, twisted

D) rubber hose outer layer damage, blistering, softening, aging, cutting, wear (any reinforcement layer exposure)

8.2 Pressure test: Run the system at maximum operating pressure, check for possible faults and leaks, and keep the test personnel away from possible hazardous areas.

8.3 Replacement cycle: must be based on past life, national or industry standards, Rubber Water Hose or to the extent of the risk of failure to determine.

Select the rubber hose should note the following:

1, rubber hose size

Including the inner diameter, outer diameter and length of the rubber hose. Reasonable choice of rubber hose diameter can minimize the pressure loss.

2, temperature

To determine the rubber hose within the transmission medium rubber hose outside the ambient temperature of both the temperature. When using rubber hoses in hot and cold environments, Rubber Water Hose consider taking appropriate measures.

3, medium

Select the rubber hose to consider the rubber hose glue should be able to match with the use of the media, the external plastic can match with the media. Need to transport a special medium can communicate with the technical company of the double rubber hose company.

4, pressure

When selecting a rubber hose, it is important to clarify the hydraulic system pressure, including the hydraulic peak. The working pressure provided on the product catalog should be greater than or equal to the hydraulic system pressure.

5, flow and flow rate

When selecting a rubber hose for a newly designed or retrofitted hydraulic system, Rubber Water Hose the appropriate rubber hose diameter should be calculated based on the flow rate and flow requirements of the different oil lines.

6, application

To meet application requirements, the following issues need to be considered:

A. Where is the rubber hose used? What is the device type?

B. Is it used for inhalation conditions (with negative pressure requirements)?

C. Can the rubber hose arrangement meet the minimum bend radius requirements? Will it wear rubber hose? Is there an abnormal mechanical load?

7, other:

7.1 Insulation or conductivity: In some cases in order to prevent the current through the rubber hose insulation requirements. In other cases, in order to release static electricity, it may be desirable for the rubber hose to have good electrical conductivity.

7.2 Penetration: When the rubber hose for gas, Rubber Water Hose liquefied petroleum gas or gas, refrigerant, the gas from the rubber hose to the external infiltration. Will make the rubber hose outside the bubble and separation. Penetration may result in high concentrations of ignition, blasting, toxic gases, fluid loss, etc.

7.3 Environment: Rubber hoses must be compatible with environmental conditions. Environmental conditions include: UV radiation, heat, ozone, moisture, water, brine, chemicals, air pollutants, etc. may cause the rubber hose to degrade or cause early Failure factor.
