wear-resisting Oxygen tube It is a key component of any hydraulic system. When they fail, everything will stop. The preventive maintenance of the metal sandblasting hose is very important and needs to be checked regularly in order to find problems before starting. This may include checking hose caps and fittings, and looking for other signs of leaks and impending hose failure. The more strict the hose inspection process, the more reliable your equipment will be. 1. Benefits of preventive maintenance of metal sandblasting hoses: preventive maintenance of metal sandblasting hoses and equipment is always better than reactive maintenance. One reason is that it can make your equipment run efficiently by solving problems before they fail and have a significant negative impact on the system. Contrary to what many people think, preventive maintenance means reducing downtime due to unexpected component and system failures. Attention to maintenance can also extend the expected life of equipment, maximize its economic value, and minimize potential safety hazards to personnel. Finally, preventive maintenance can reduce maintenance costs and unnecessary equipment procurement. Not participating in regular preventive maintenance can be an expensive decision. 2. Maintenance time of metal sandblasting hose: Oxygen tube company Part of the preventive maintenance program for solid metal sandblasting hoses includes periodic inspection of metal sandblasting hoses. Fixed equipment shall be inspected every three months. For mobile equipment, hose inspection shall be conducted every three months or every 400 to 600 hours, whichever comes first.
1. The use of protection cannot be ignored: the long-term use of high-pressure sand blasting hose joints at home usually does not cause concern, but excessive use and improper protection also buried the hidden danger of joint cracking to a certain extent. It is understood that the service life of the joint is usually 200000 times, and it should be replaced after long-term use. When using the side, Oxygen tube company Care should be taken to close and open as gently as possible and not to rotate the knob of the hose connector repeatedly. 2. Differentiation of quality can be based on standard evidence collection. It is understood that it is still difficult to determine the cause of joint cracking. At present, the National Bureau of Technology and Quality Supervision has issued recommendations for sealing nozzles and hose specifications. These two specifications perfectly adjust the quality specification target of connectors and hoses. Consumers can go to the quality inspection department to check the torsional strength of the connecting hose, the tightness of the connecting spool and the strength of the connecting materials. If the content of standard rules cannot be met, it will be attributed to quality problems, which can serve as a strong basis for expression. 3. The appearance of hose connector is difficult to distinguish between good and bad. In order to pursue profits and reduce costs, many manufacturers currently use selected cast iron (easy to rust) and zinc alloy (non anti-corrosion) as materials to produce high-pressure sand blasting hose joints, which causes product quality problems. It is understood that the quality of connectors and hoses is not up to standard, Binzhou Oxygen tube The strength function and sealing function of high-pressure sand blasting hose joints are not up to standard due to problems such as materials and wall thickness, which should be paid attention to by consumers.
Binzhou Oxygen tube With the continuous updating of technology, the products are also developing in the continuous updating. At present, the inspection requirements of rubber hose are also improved compared with the previous ones. The inspection index of ultra-high pressure hose shall meet the following index requirements according to the requirements of the Safety Code for High Pressure Water Jet Cleaning Operation: 1) The bursting pressure shall be more than 2.5 times of the working pressure. 2) The test pressure shall be 1.5 times of the working pressure, and the pressure shall be kept for more than 2 minutes without damage. 3) Pulse pressure shall be within the range from zero to working pressure, and 50000 pressure pulses shall be free of damage; The pulse frequency is 15 times/min when the working pressure is 1000-2800bar, and 110 times/min when the pressure is above 2800bar. Since high-pressure cleaning machine has been widely used in all walks of life, and the working condition of high-pressure hose is relatively the worst, we must pay attention to the quality when selecting high-pressure hose, so as to avoid unnecessary safety accidents. Oxygen tube company The development of rubber hose can not be separated from cooperation, R&D and innovation can not be separated from communication, and the inspection requirements of rubber hose have been improved compared with the previous ones. The storage site shall be free of ozone, heat source and equipment generating electromagnetic field. The coiled hoses or hose assemblies shall be stored horizontally, and the stacking height shall be limited to the extent that the products at the bottom will not produce permanent deformation.
If conditions permit, secondary vulcanization shall be adopted, wear-resisting Oxygen tube Effectively remove the odor generated during the consumption of odorless hose. Pay attention to the volatilization of various ingredients in the odorless hose formula. When the odorless hose is consumed, in addition to paying special attention to the raw materials and vulcanization process of the reclaimed rubber, pay attention to the selection of various ingredients and whether they will volatilize in the vulcanization process. The volatilization of vulcanizing agent, accelerator and antioxidant will produce a great smell. It is very important to accurately determine the length of the required rubber sand blasting pipe by using the rubber sand blasting pipe. It shall also be checked whether the use conditions of the rubber sand blasting pipe meet the requirements of the selected rubber sand blasting pipe. It should be ensured that the rubber sand blasting pipe you will use is the most suitable one. The working pressure and suction should be carefully determined. Special attention shall be paid to the test standard pressure change or pressure peak of wear-resistant sand blasting pipe. Exceeding the promised maximum value will greatly shorten the service life of the rubber sand blasting pipe. Both ends of the rubber sand blasting pipe cannot be continuously immersed in the transported material. If the bending radius of the rubber sand blasting pipe is less than the minimum value, Binzhou Oxygen tube Its service life will be greatly shortened. Therefore, before installation, it is recommended that you consult the application of information, especially the information about the bending radius of the rubber sand blasting pipe. Protection and cleaning of rubber sand blasting hose: it is recommended to empty the hose after use. Clean if necessary. Inspection: After each use, the rubber sand blasting pipe must be inspected to ensure that it does not show structural damage.
wear-resisting Oxygen tube The inner rubber layer of（ ф 0.3-2.0 reinforcement layer) is the skeleton material that plays the role of reinforcement. What should be paid attention to when storing the wear-resistant sandblasting pipe. 1. The wear-resistant sandblasting pipe should be stored as loose as possible. Generally, rubber hoses with inner diameter less than 76 mm can be wound and stored. 2. During the storage of wear-resistant sand blasting pipe, it is strictly prohibited to stack heavy objects on the pipe body to prevent external extrusion and damage. 3. During the storage of wear-resistant sand blasting pipe, do not contact with acid, alkali, oil, organic solvent or other corrosive liquids and gases, and the heat release should start from 1m away. 4. The storage period of wear-resistant sand blasting pipe shall not exceed 2 years, and it shall be used by the first person to prevent the quality of rubber pipe from being affected by long-term storage. 5. When wear-resistant sand blasting pipes need to be temporarily stored in the open air, the site should be flat and the rubber pipe should be laid flat. The upper cover should be placed under the rubber pipe and no heavy objects should be stacked. At the same time, the hose shall not contact the heat source. 6. The storage place of the upper and lower rubber pipes in the well shall be kept clean and ventilated, and the relative humidity shall be 80. The temperature of the storage place shall be kept between - 15 ℃ and 40 ℃, and the rubber pipe shall be protected from direct sunlight and water spray. 7. When storing wear-resistant sand blasting pipe, Oxygen tube company Both ends of the hose shall be sealed firmly to prevent sundries from entering the hose. 8. When the wear-resistant sand blasting pipe is stored, it should be placed separately according to different varieties and specifications, not mixed, and hang the management board. 9. In order to prevent the pipes from being pressed and deformed during storage, they should not be stacked too high, and the stacking height should not exceed 1.5m. It also requires rubber hoses to be "stacked" frequently during storage, at least once a quarter.
Binzhou Oxygen tube There are many specifications.
