I believe everyone is familiar with wear-resisting Suction and discharge pipe Relevant application knowledge of products. It is understood that at present, this product is mainly used for mining hydraulic support and oilfield development. It is applicable to engineering construction, lifting transportation, metallurgical forging, mining equipment, ships, injection molding machinery, agricultural machinery, various machine tools, mechanization of various industrial departments, water-based liquids, etc. And liquid transmission. Its relatively high working pressure can reach 70-120 MPa. In order to achieve better application effect, what problems should be paid attention to when using high-pressure braided hose? 1. The bending radius shall not be less than the given bending radius to prevent damage to the hose skeleton or premature failure due to excessive tension. 2. Select the type and specification of the hose correctly according to the use conditions, and do not misuse or replace it. 3. When using high-pressure braided hose, the pressure should be adjusted slowly and evenly to avoid sudden pressure increase and damage to the pipe body. 4. When the work site changes, it should be removed from the ground without dragging, so as to avoid the skeleton layer being corroded after scratching the outer glue. 5. After delivering corrosive liquid, the interior should be cleaned to prevent residues from corroding the pipe body for a long time, or select corresponding series of products. When storing high-pressure braided rubber hoses, depending on the type of rubber used, Suction and discharge pipe company Note which conditions typically change over time. However, due to several factors or a combination of several factors, this change may accelerate, and other materials used to strengthen high-pressure braided hoses may also be adversely affected by improper storage conditions.

Zhengzhou Suction and discharge pipe 1. The manufacturing quality shall be guaranteed according to the national standards of Oxygen Hose (GB/T2550-91) and Acetylene Hose (GB/T2551-91) respectively, and the hose shall have sufficient compressive strength and flame retardant characteristics. According to the national standard, the oxygen hose is red, the working pressure vessel is 1.5MPa, the inner diameter of the hose is 8mm, and the outer diameter is 18mm; 2. Care must be taken when storing and using the hose to keep it clean and free from damage. For example, avoid exposure to sunlight, rain and snow, and prevent contact with substances such as acid, alkali, oil and other organic solvents that can damage the hose. The storage temperature shall be - 15 ℃~40 ℃, and the distance from the personnel shall not be less than 1m; 3. When using a new hose, the talcum powder on the inner wall of the hose must be blown out first to prevent the channel of the welding torch from being blocked. Avoid external extrusion and mechanical damage during use, and do not fold the pipe body. 4. If the oxygen hose catches fire, stop the air supply first, and then deal with the fire hose, but do not bend the hose. The cylinder valve must be closed when the cylinder is not in use or after work. 5. The hose with bulge, crack or air leakage shall not be used, and the air leakage hose shall not be used after being stuck with adhesive tape. Suction and discharge pipe company When connecting the two ends of the hose with tools, clamp or wire shall be used to fasten, and the intermediate joint shall be fastened with a gas pipe connector.

Zhengzhou Suction and discharge pipe There are many specifications. Different installation positions require different specifications of cloth clamping sand blasting pipe, and the specification selection of cloth clamping sand blasting pipe has different requirements. The following small series will briefly introduce them to you: 1. Temperature: The selection should be based on the ambient temperature when the cloth clip sandblasting pipe is working. In case of high temperature, the temperature correction pressure shall be determined according to the working pressure and temperature correction coefficient of the cloth sanding pipe under high temperature to determine the correct pressure level. 2. Pressure: when selecting the cloth clip sandblasting pipe, check the nominal diameter and pressure gauge of the corrugated cloth clip sandblasting pipe according to the actual working pressure of the hose to determine whether to use the stainless steel mesh sleeve type. 3. Size: select the joint type, size of cloth sanding pipe and hose length according to the size of cloth sanding pipe. 4. Medium: determine the material of each part of the hose according to the chemical properties of the material medium transported in the cloth sanding pipe and the corrosion resistance of the hose material. 5. Status: According to the use status of the hose, refer to the correct use and installation method of the cloth clip sandblasting pipe and the length of the hose in the settlement compensation. Therefore, Suction and discharge pipe company According to the actual pressure of the system, the higher the working pressure of the cloth clamping sand blasting pipe is, the normal operation of the system can be ensured, and the appropriate cloth clamping sand blasting pipe is selected.

We all know Suction and discharge pipe company The noise pollution in industrial production is very serious, and noise pollution is also an important factor affecting workers' enthusiasm for production. Ball mills were once a major source of noise in mining equipment. In order to reduce the noise generated by ball mills, protect the physical and mental health of workers, improve workers' enthusiasm for production, and create greater profits for the company, Through the efforts and research of domestic and foreign industry experts, the ball mill liner has been transformed. Through repeated tests and comparison, it is found that the noise generated by the rubber liner and the manganese steel liner of the ball mill is far less than the manganese steel liner when the technical parameters are up to standard. According to the data provided by the noise monitoring station and the concentrator, We analyzed the noise intensity and the economic benefits: the domestic ND2 precision sound level meter and octave filter were used for detection, and the sound level meter was calibrated by the provincial sound level meter measurement and verification station; There is no sound insulation room in the ball mill workshop. The monitoring points are arranged according to the position of the ball mill and the flow of workers to observe the mechanical operation, 2m away from the sound source. One monitoring point is respectively set on the left and right of the east and west of the workshop and in the middle of the two ball mills. The measurement method is in accordance with the Noise Detection Specification for Industrial Enterprises. As the noise in the workshop is continuous and steady, sound level A is used as the evaluation basis. The rubber lining plate is manufactured by Hainan Rubber Lining Plate Factory according to the ball mill shell structure and the original manganese steel lining plate specification (1.4mx0.74mX0.07m). Zhengzhou Suction and discharge pipe First, take out the manganese steel lining plate in the ball mill barrel, and then install the rubber lining plate in the barrel in turn (front and back). Each ball mill is installed with 48 pieces. First, use the pressure strip to compress, and then use the screws to fix the rubber lining plate on the ball mill barrel, so as to prevent falling off when rotating. The noise intensity of the ball mill workshop with manganese steel liner is 94-103dB (A), while the noise intensity of the ball mill workshop with rubber liner is 87-92dB (A), and the noise reduction difference is 7-11dB (A). The rubber liner has good noise reduction effect.
