  • What is the current situation and future direction of the construction machinery industry?

      With the continuous advancement of technology and the acceleration of industrialization, construction machinery, as an important equipment in modern fields such as construction, transportation, and water conservancy, is playing an increasingly important role. The widespread application of construction machinery not only improves construction efficiency and reduces labor intensity, but also promotes the development of related industries and makes great contributions to the country’s economic construction.   1、 Common Classification of Construction Machinery Engineering machiner...

  • What are the breakthrough points of hydraulic transmission?

    1. Control of oil leakage issues The hydraulic control system has a variety of application scenarios, and it is prone to problems during use, one of which is oil leakage. leakage not only leads to the contamination of hydraulic oil but also severely affects the normal operation of the control system. This is mainly because hydraulic oil plays a crucial role the transmission and control processes of mechanical equipment, and the control of hydraulic oil temperature is particularly strict. If the hydraulic oil operates for a long time in an overhe state, it will affect the normal operation of...

  • Super soft hose

    Speaking of hoses, everyone’s impression might be that they are soft, capable of conveying fluids, and similar to the transparent water pipes at home Before joining the Weilan platform, I also had this understanding. In fact, in the world of hoses, there are many special products, such as the antivehicle pressure hoses introduced earlier. Today, I want to introduce to you the “excellent student” of the hose family – the ultra-soft hose 1. Why choose ultra-soft tubing? In practical applications, the need for special flexible hoses is very common, mainly due to the fo...

  • PTFE Hose vs. PVC Hose: Differences and Characteristics

      In fluid transfer systems, hoses serve as the critical bridge between equipment and media, and their performance directly affects the stability and safety of the system PTFE hoses and PVC hoses, as two common types of hose materials, each have unique advantages and applications. Understanding the differences between them can help us make reasonable choices based on actual needs. Chemical composition and stability   The PTFE hose is made of polytetrafluoroethylene material, which has extremely high chemical stability and is almost unaffected by any substances. It can resist the attack o...

  • How to ensure reliable sealing of high-pressure tube fittings with O-ring seals?

    O-ring Both SAE flange seals and O-ring end seals are sealed by O-rings. These fittings are generally used in applications with very high pressure and the reliability requirements for machinery equipment are also very high. These application occasions are generally static pressure seals. How can we ensure the reliability of O-ring seals The sealing principle of O-rings used in static pressure sealing After the O-ring is installed in the sealing groove, its cross-section is subjected to contact pressure, resulting in elastic deformation, and generates a initial contact pressure P0 on the con...
