Luoyang Acid and alkali resistant rubber hose It is widely used in mining, chemical industry, construction and iron and steel fields. At present, 90% of ball mills, rod mills and moistening mills on the market still use manganese steel cylinder liners, and the manganese steel material consumed on liners alone every year is more than one million tons. The emergence of rubber liners is favored by many big customers in the ball mill field. What are the indexes that affect the rubber lining plate of the ball mill? 1. Conditions of ball mill use scenario The feeding particle size of ore also plays an important role, so a good ball mill rubber lining plate will be designed according to the size of the customer's mill, feeding particle size, and steel ball diameter. Select the rubber formula suitable for customers, and carry out mapping, design, testing and processing. 2. Rubber formula and processing technology: The rubber material and formula directly affect the performance of the rubber lining plate of the ball mill. Wear resistance is a key factor. It is impossible to determine how long its service life is because of the impact of industrial and mining conditions. The second is corrosion resistance. This is the characteristic of the formula, so even if the appearance is the same, the performance is an advantage. Do not buy for cheap. 3. Regular maintenance: everyone knows that the rubber lining plate of the ball mill is fixed to the cylinder by means of T-bolts, so it is also very important to regularly check the tightness of the bolts and the wear of the rubber strips inside the cylinder. In order to avoid damaging the rubber lining plate of the cylinder and the cylinder of the ball mill when the lifting strip is worn out, the gain is not worth the loss. Acid and alkali resistant rubber hose company One of the advantages of the manganese steel lining plate is that the replacement is simple and only needs two people to operate, and it can be replaced wherever it is broken. This is an advantage that the manganese steel lining plate does not have.
Luoyang Acid and alkali resistant rubber hose It is mainly used for the transportation of liquid and gas. The use requirements of cloth clip sand blasting pipe are stricter than those of ordinary rubber hose. The so-called high voltage puts forward this requirement. The following small series will introduce the use requirements of cloth clip sandblasting pipe. According to the use characteristics of cloth clip sand blasting pipe, the larger working pressure of cloth clip sand blasting pipe is determined according to the system pressure. Each cloth clamping sand blasting pipe has a normal working pressure, and the bursting pressure of cloth clamping sand blasting pipe is 3-4 times of the larger working pressure. The higher the pressure, the higher the number of steel wire layers, and the more stringent the product production. Therefore, according to the actual pressure of the system, the higher the working pressure of the cloth clamping sand blasting pipe, the normal operation of the system can be ensured, and the appropriate cloth clamping sand blasting pipe can be selected. If the impact pressure of the system is frequent, the cloth clip sandblasting pipe with high pulse life shall be selected, and the specification and model classification of the cloth clip sandblasting pipe shall be properly improved. Temperature is also one of the factors considered by customers. Acid and alkali resistant rubber hose company The high and low temperature transition in the working environment will affect the service life and pressure bearing capacity of the rubber hose. Therefore, high-pressure rubber hoses should be used within their allowable range. For the system whose long-term operating temperature is not within its allowable range, hose sheath or special rubber hose shall be purchased.
Whether in the process of purchase or use, production Acid and alkali resistant rubber hose The quality of all needs to be checked regularly. During the inspection, the following items should be noted. 1. Standard size and actual error of high-pressure rubber hose: because the inner diameter and outer diameter of high-pressure sand blasting pipe and the outer diameter of the skeleton layer will shake, if the shaking amplitude exceeds the allowable limit, the balance of the buckling amount of the sand blasting pipe joint cannot be guaranteed, and the quality of the sand blasting pipe assembly cannot be guaranteed. Therefore, for the sand blasting pipe selected for the production of sand blasting pipe assembly, it is necessary to strictly check whether the inner diameter and outer diameter of the skeleton layer meet the requirements, and the requirements for the outer diameter error can be appropriately relaxed. 2. Wall thickness error of high-pressure hose: due to the local pain of the rubber layer in the high-pressure sandblasting pipe and the influence of the overlapping width of the rubber layer of the high-pressure sandblasting pipe quality inspection center between the skeleton layers, the wall thickness error of the sandblasting pipe may be too large. If the wall thickness error exceeds the allowable range, it will affect the tightness and pull-out strength of the connector, and even cause some deflection (tilting head) of the hose assembly connector. Quality inspection of high-pressure sand blasting pipe Therefore, the wall thickness error of sand blasting pipe should be strictly controlled. Generally, the rubber hose with wall thickness error exceeding 0.5mm shall be selected stably. 3. Adhesion between each layer of high-pressure rubber hose: high-quality high-pressure sand blasting pipe shall have prominent integrity, that is, the quality inspection of high-pressure sand blasting pipe shall have high adhesion between each structural layer, and the adhesion between each adhesive layer shall become an integrity. Only in this way can we meet various technical requirements in the process of joint installation and fastening, and only in this way can we ensure the quality inspection requirements of high-pressure sand blasting pipes for sand blasting pipe assembly. Therefore, Acid and alkali resistant rubber hose company It is necessary to control the adhesive force between each layer of the rubber hose not lower than that specified in the technical standard, and the rubber hose with high adhesive force shall be selected as far as possible to produce the rubber hose assembly.
If conditions permit, secondary vulcanization shall be adopted, production Acid and alkali resistant rubber 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, Luoyang Acid and alkali resistant rubber 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 Acid and alkali resistant rubber hose 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: Acid and alkali resistant rubber hose 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.
Luoyang Acid and alkali resistant rubber 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.
