Qingdao Sanding pipe 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. Sanding pipe 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.
wear-resisting Sanding pipe 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, Sanding pipe 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.
Air duct mainly refers to the ventilation duct of the central air-conditioning system, which is often ignored, but it is an important part of the air-conditioning system. Qingdao Sanding pipe What are the regulations for welding air ducts? Gongfa HVAC is a manufacturer dedicated to the production of air ducts, which has been recognized and supported by the majority of users for many years. 1、 The welding regulations of carbon steel plate air duct are as follows: 1. The carbon steel plate air duct should be welded by DC welder. Introduction to welding air duct If AC welding machine is used for welding, a vibrator must be added to reduce excitation and stabilize the arc. When welding steel plates, the arc is unstable, which can lead to deterioration of weld quality. 2. Before welding, remove the dirt, oil stain and rust at the welding port; When spot welding or continuous welding is used, the oxide shall also be removed. The butt joint shall be kept with the minimum gap, and the overlap at the manual spot welding location shall be removed in time. After welding, the electrode slag and residual welding wire in the weld and its surrounding area shall be removed in time. 2、 The welding regulations of stainless steel air duct are as follows: 1. Before welding the air duct, remove the grease and dirt in the weld area to prevent pores and sand holes in the weld. Cleaning can be carried out with gasoline, acetone, etc. When welding stainless steel plates by electric arc welding, the surfaces on both sides of the weld should be coated with white ash, Qingdao Sanding pipe To avoid welding slag splashes adhering to the surface of the plate. 2. After welding, attention shall be paid to removing the slag at the weld, brushing the metal luster with a copper wire brush, pickling with 10% nitric acid solution, and then cleaning with hot water.
In the shipbuilding industry, radio industry, electrical industry, telecommunications industry, instrument industry, aviation industry, medical industry, etc., we often see acid and alkali resistant hose, then what is Qingdao Sanding pipe What about? If you want to know more, please read down! Acid and alkali resistant silicone hose is a kind of pipe specially used for power equipment, which uses acid and alkali resistant silica gel as the main raw material and tightly wraps the pipe wall with electrical grade polyethylene spiral wire. Due to the chemical inertia of acid and alkali resistant silica gel, this kind of pipe has good acid and alkali resistance performance and electrical performance, and is commonly used in the production of wires, cables and lead wires in extreme acid and alkali environments. Also called: acid and alkali resistant silicone rubber hose, acid and alkali resistant silicone rubber hose, acid and alkali resistant silicone rubber hose, acid and alkali resistant silicone rubber hose, acid and alkali resistant silicone rubber hose. Features: 1. High temperature resistance (250-300 ℃) and low temperature resistance (- 40-60 ℃); 2. Good acid and alkali resistance. Physiologically stable, able to withstand repeated harsh and disinfection conditions, resistant to ozone aging, light aging, weather aging and ultraviolet radiation. 3. Small resilience and permanent deformation (no more than 50% at 200 ℃ for 48 hours), breakdown voltage (20-25KV/mm), ozone resistance and UV resistance. Sanding pipe company Radiation resistance and other characteristics, 4. Good electrical performance, small change when exposed to moisture, water or temperature rise, even if the silica generated by short circuit combustion is still an insulator, which ensures that electrical equipment continues to work, so it is most suitable for making wires, cables and lead wires.
wear-resisting Sanding pipe Or PVC steel wire spiral reinforced pipe. The commodity is made of high-quality PVC plastic raw materials. PVC steel wire reinforced pipe is also a PVC steel wire reinforced hose that uses steel wire reinforcement. The embedded spiral steel wire is used as the reinforcement layer, so the product has both rigidity and flexibility, that is, it has both satisfying mechanical properties and rigidity, and excellent flexibility. The reinforced pipe of latex fiber is PVC hose embedded with steel wire framework. The inner and outer tube walls are clear, lubricated, free of bubbles, and the fluid transportation is clearly visible. Silicone fiber tube is resistant to low concentration of acid and alkali, high elasticity, not easy to age, and has a long service life. Resistant to high pressure and can be kept intact under high pressure and vacuum. PVC steel wire pipe is made of new PVC reinforced materials, and has made great progress in compressive strength and hardness. The main production method of silica gel steel wire pipe is multiple production method. The main types of steel wire pipe in shopping malls include high pressure steel wire pipe, low pressure steel wire pipe, steel wire skeleton pipe and Tongming steel wire pipe. The application methods are different in different environments. The new PVC steel wire pipe is the most widely used commodity today. Sanding pipe company After use, it will not be the same as the metal pipe, which is easy to deform and leak. What advantages does the PVC fiber reinforced pipe have.
