Cord hose company The following recommendations contain a series of precautions to prevent items from aging to a greater extent during storage. 1. During storage, the rotating plan system shall be adopted to shorten the storage time of high-pressure braided hose as much as possible. If long-term storage cannot be avoided and the following recommendations cannot be followed, high-pressure braided hoses should be thoroughly inspected before use. 2. Physical storage conditions: The high-pressure braided hose must be stored without mechanical pressure, including excessive stretching, compression or deformation, and without contact with sharp or sharp objects. High pressure braided hoses should be stored on suitable supports or on dry ground. High pressure braided rubber tubes packaged as coils must be stored horizontally. High pressure braided rubber pipes shall not be stacked. If stacking cannot be avoided, the stacking height shall not cause permanent deformation of the high-pressure braided rubber pipe below. Pumping high-pressure hydraulic hose is a common high-pressure hydraulic hose. In order to ensure the operation safety of the pumped high-pressure hydraulic hose, the following small series will briefly introduce the correct use of the pumped high-pressure hydraulic hose: 1. Before each use of the high-pressure hydraulic hose, the surface of the high-pressure hydraulic hose must be evenly coated with soap liquid, which can play a non bonding role between the high-pressure hydraulic hose and the concrete, and play a lubricating role in the drawing process, It can greatly increase the reuse times of high-pressure hydraulic hoses. 2. Installation: first, insert the steel hinge wire into the inner hole of the draw tube to avoid extrusion deformation when pouring concrete. Then, pull out the high-pressure hydraulic hose coated with soap liquid from the prestressed hole and fix it in the correct position with a fixing ring. The spacing of the retaining rings is controlled by the suspension and is usually about 500 mm. production Cord hose When connecting the high-pressure hydraulic hose, wrap both ends of the high-pressure hydraulic hose for one and a half weeks or two weeks with thin iron sheet or PVC pipe (vertical cutting), fix them with iron wire, and then seal both ends of the PVC pipe with tape to avoid entering the mortar.
polyurethane production Cord hose Maintenance measures; Cleaning: It is recommended to empty the hose after use. Clean if necessary. Inspection: After each use, the rubber tube must be inspected to ensure that there is no structural damage. Pressure: If the rubber pipe is under great pressure during use, or the outer layer of the rubber pipe will contact with the conveyed liquid for a long time, it is recommended to conduct a hydrostatic test. Due to the natural characteristics of rubber, the physical properties and performance levels of all rubber products will change. This change usually occurs over time, depending on the type of rubber used. However, changes may also accelerate due to several factors or a combination of several factors. Other materials used to reinforce rubber tubing may also be adversely affected by improper storage conditions. Detailed step 1. Polyurethane sand blasting pipe mandrel: the mandrel is usually pulled backward, mainly to increase the firmness of the connection between the mandrel and the hose. After the spindle barb processing is completed, the barb tip must also be passivated, otherwise the barb tip will pierce the lining material of the high-pressure rubber tube during the buckling process. Cord hose company Even if the high-pressure rubber pipe joint is firmly buckled, if the inner layer is damaged, high-pressure water will leak from the buckle. 2. Polyurethane sand blasting pipe sheath: the sheath is generally in the form shown in the figure, the wall thickness should be moderate, and the internal rectangular tooth height should not exceed 2mm, that is, (d-d) should not exceed 4mm.
Nanchang Cord hose Structure type of product: sand blasting hose is mainly composed of liquid resistant inner rubber layer, middle rubber layer, 2 or 4 or 6 layers of steel wire winding reinforcement layer and outer rubber layer. The inner rubber layer has the function of bearing the pressure of the transmission medium and protecting the steel wire from erosion, the outer rubber layer protects the steel wire from damage, and the steel wire (0.3-2.0 steel wire) layer is the reinforced skeleton material. Application of sandblasting hose products: high-pressure sandblasting hose is mainly used for mining hydraulic support and oil field exploitation, and is suitable for engineering construction, lifting and transportation, metallurgical forging, mining equipment, ships, injection molding machinery, agricultural machinery, various machine tools, and mechanical and automatic hydraulic systems in various industrial sectors to transport petroleum base with a certain pressure (higher pressure) and temperature. (such as mineral oil, soluble oil, hydraulic oil, fuel oil, lubricating oil) and water-based liquid (such as emulsion, oil-water emulsion, water). And liquid transmission. The working withstand voltage can reach 70-100 MPa. The company's sand blasting hose standards refer to national standards/T10544-03, DIN 20023, and SaE100 R9-13. Cord hose company Made of special synthetic rubber, it has excellent oil resistance, heat resistance and aging resistance. The rubber hose has high bearing pressure and superior pulse performance. The tube body is tightly combined, soft to use, and has little compression deformation. The hose has excellent bending resistance and fatigue resistance. The sandblasting hose is 20m long and can be made within 50m as required.
If conditions permit, secondary vulcanization shall be adopted, production Cord hose 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, Nanchang Cord hose 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.
production Cord hose It will burst for a long time due to frequent and severe pressure shocks. This situation is usually not caused by excessive static pressure, but is related to the strength and frequency of pressure shock. During the operation of construction machinery, the oil pressure in the oil resistant hose will rise or fall repeatedly, and then it will form frequent pressure shocks to the oil pipe, causing the oil seal of each part to become more damaged, the oil resistant hose will bubble and break, and the pipe joint will become loose and leak. Therefore, in the process of operation, the valve rod should not be pulled too hard, and it needs to be gentle. The application temperature of the oil in the oil resistant rubber hose is too high, resulting in aging and bursting of the rubber hose. During the operation of construction machinery, the hydraulic system will cause the oil to become hot due to power failure, and the influence of external temperature (especially in summer) will cause the oil temperature to rise sharply. The higher the oiling temperature is, the easier the rubber hose ages, the worse the elasticity is, the lower the strength and sealing function are, and the oil resistant hose will burst quickly. Therefore, Cord hose company During operation, when the temperature rise of the hydraulic system is too high or too fast, the causes should be found and eliminated in time. Necessary cooling measures shall be taken for summer operation, especially continuous operation.
