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, Air compression hose 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, Texas Air compression hose 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.

Texas Air compression hose 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. Air compression hose 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.

Texas Air compression hose It is used for transportation, construction and other operating equipment. Incorrect operation and incorrect environment may affect the normal use of steel braided sandblasting pipe. What specific factors will affect the normal use of steel braided sand blasting pipe? The quality will definitely affect the use effect. The poor quality is actually related to the selected raw materials. Some raw materials are of high quality, and the quality of steel braided sandblasting pipes produced is also very good. However, if the steel braided sand blasting pipe is made of inferior plastic, the quality is very poor, which also affects the use effect. The use environment affects the use effect. Anti static steel braided sand blasting pipe is usually used in industry. Because these products are very common, the demand is also large. However, people do not pay attention to the use environment. If used in strong acid and alkali environment, steel braided sand blasting pipe will naturally corrode. Or if used in a relatively high temperature area, the steel braided sandblasting pipe may melt. Anti static steel braided sand blasting pipe will also affect the use effect. In the eyes of most users, the greater the degree, the better the nature. So if you choose a good one, users can use it with confidence. Understanding and avoiding the wrong use of high-pressure pipeline can reduce the possibility of high-pressure pipeline failure. The following brief introduction will help you. 1. Frequent and serious pressure shock: high-pressure pipeline burst is generally not caused by excessive static pressure, but is related to the severity and frequency of pressure shock. During the operation of construction machinery, the sudden increase or decrease of oil pressure in the high-pressure pipe will occur repeatedly, which will cause frequent pressure shocks to the oil pipe, leading to the aggravation of oil seal damage at various parts, blistering and cracking of rubber hose, and loosening and leakage of pipe joints. Therefore, during operation, the valve rod shall not be pulled too hard, but must be pulled gently. 2. The use temperature of oil is too high: during the operation of construction machinery, due to the power loss of the hydraulic system, the oil will rise, and the external temperature (especially in summer) will lead to a sharp rise in the oil temperature. production Air compression hose company The higher the oil temperature is, the easier the rubber is to age, the worse the elasticity is, the lower the strength and sealing performance are, and the high-pressure pipe will burst rapidly. Therefore, when the temperature rise of the hydraulic system is too high or too fast during operation, the causes should be found out and eliminated in time. For summer operation, especially continuous operation, necessary cooling measures shall be taken.

Air compression hose company It has become the standard configuration of the modern new ball mill, but many problems may occur during the use or installation of the rubber lining plate, which will cause the failure of the rubber lining plate of the ball mill. Here is a brief introduction to the causes of the more common failure of the rubber lining plate of the ball mill. The design and installation are not professional and reasonable. The design and installation are also common problems for many novice manufacturers. For example, the bolt holes for fixing the ball mill lining plate are square, which will cause stress concentration and fracture. Adjust the size of lining plate to control the gap between lining plates at about 8mm; The installation quality of lining plate is very important to the safe operation of ball mill. First, tighten the fixed wedge symmetrically, put the lining plate in sequence, and then use the tightening wedge to secure it; Therefore, professional installation guidance can easily avoid these problems. The reason why the rubber lining plate of the ball mill does not match the steel ball is relatively common, and it is easy for many novice manufacturers to ignore and make mistakes. During the operation of the ball mill, the rubber lining plate of the ball mill, materials and steel balls promote the normal grinding and crushing of the ball mill due to the interaction of forces. The hardness of materials is related to wear resistance, and the wear resistance increases with the increase of hardness, Texas Air compression hose It is a pair of friction pairs, and the increase of hardness of one side will cause the wear of the other side to increase. Therefore, the high wear-resistant rubber lining plate is matched with the high wear-resistant steel ball, and the low wear-resistant rubber lining plate is matched with the low wear-resistant steel ball, so as to ensure the normal wear of the rubber lining plate of the ball mill and extend the service life of the ball mill.
