Các sản phẩm ống thủy lực chủ yếu được sử dụng để hỗ trợ thủy lực mỏ, khai thác mỏ dầu, thích hợp cho xây dựng cơ khí, nâng và vận chuyển, rèn luyện kim, thiết bị khai thác mỏ, tàu, máy ép phun, máy nông nghiệp, máy công cụ khác nhau và cơ giới hóa và tự động hóa các hệ thống thủy lực các lĩnh vực công nghiệp Nó có thể vận chuyển dầu mỏ - gốc (chẳng hạn như dầu khoáng, dầu hòa tan, dầu thủy lực, dầu nhiên liệu, dầu bôi trơn) và chất lỏng gốc - nước (chẳng hạn như nhũ tương, dầu - nhũ tương nước, nước) và chất lỏng có áp suất và nhiệt độ nhất định (áp suất cao hơn).
For transmission, the maximum working pressure can reach 60MPa. Precautions for hydraulic hoses 1. Inner diameter of the tube: the inner diameter of the hose. 2. The following matters should be paid attention to in the use and design of the hose: 1. The bending radius of the hose should not be too small, and generally should not be less than the value specified in "Technical Characteristics of Hydraulic Hose Assembly". There should be a straight section at the connection between the hose assembly and the pipe joint, and the length of this section should not be less than twice the outer diameter of the pipe. 2. The length of the hose assembly should take into account that the length of the hose will shrink and deform after the pressure oil is introduced into it. Generally, the shrinkage amount is 3 to 4 percent of the length of the hose. Therefore, when the hose assembly is installed, it is not allowed to be in a tensioned state. 3. The hose assembly should be installed without torsional deformation. The joint axis of the hose should be placed in the moving plane as much as possible to avoid damage to the hose when the two ends move with each other. 4. The hose should avoid contact and friction with the sharp corners of the machine to avoid damage to the tube. Safety Measures for Hydraulic Hose In order to ensure the safe and reliable use of the hose assembly, pay special attention to the following matters. 1. Pressure: Normally, the specified working pressure of the hose cannot be less than the maximum system pressure. Only in the case of infrequent use, it is allowed to increase by 20 percent ; for those who use it frequently and often bend it, it should be reduced by 40 percent . If the impact pressure of the system is higher than the specified working pressure of the hose, it will not only reduce the service life of the hydraulic hose, but also may cause personal equipment accidents. 2. Temperature: The fluid temperature and ambient temperature, whether stable or instantaneous, must not exceed the temperature resistance limit of the hose, and the temperature is lower or higher than the recommended temperature of the hose, which can reduce the performance of the hose and cause the hose. damage, resulting in leakage. 3. Fluid compatibility: The fluid in the hose should comply with the regulations made in the "Use" in the product sample. Use beyond the regulations cannot guarantee the service life and safety of the tube. 4. Appropriate end connection: It is widely used due to the convenience of nut connection and low cost, but in the case of large vibration, the looseness of the nut should be fully considered and flanged connection should be adopted. Hydraulic hose connection method 1. Compression fitting connection - pressure range: 250-800 Bar; applicable steel pipe size range: 4-42 mm; applicable material: carbon steel and stainless steel.
