Description

Condenser copper pipe fixing device capable of preventing vibration and abrasion Technical Field The invention relates to the technical field of condenser copper pipes, in particular to a condenser copper pipe fixing device capable of preventing vibration and abrasion. Background The condenser is used as core heat exchange equipment in the fields of refrigeration, chemical industry, ships and the like, and the installation stability of the copper pipe in the condenser directly influences the heat exchange efficiency and the service life of the equipment. In the running process of the condenser, the factors such as compressor vibration, fluid disturbance, equipment start-stop impact and the like can cause continuous radial and axial vibration of the copper pipe, so that the copper pipe and the fixing device are in a dynamic friction state for a long time, and further the problems of contact surface abrasion, copper pipe loosening and the like are caused. The existing condenser copper pipe fixing device mainly depends on an elastic supporting structure (such as a rubber pad and a spring clamp) or a rigid clamping structure to realize fixation, but has the obvious defects that firstly, an elastic part of a vibration damping structure is easy to fatigue and age due to long-term vibration, so that vibration damping effect is attenuated, vibration energy cannot be continuously counteracted, further friction and abrasion of a copper pipe and the fixing device are aggravated, an effective autonomous repairing mechanism is lacking after abrasion is generated, manual periodic disassembly and maintenance are needed, operation and maintenance cost is increased, continuous operation of equipment is affected, secondly, a memory alloy fixing device is partially adopted, external energy sources (such as electric heating) are needed to trigger a shape memory effect to realize rebound reset, energy consumption is high, adaptability is limited, and the complex working conditions of sealing and wetting of the condenser are difficult to adapt, thirdly, the existing copper pipe and clamp contact part has no automatic repairing function due to a wearing surface caused by friction, fatigue crack is easy to be generated at the wearing part of the copper pipe, and especially, the crack expansion of the thin-wall copper pipe can be caused, and medium leakage and equipment shutdown are caused. In addition, the traditional fixing device lacks real-time perception of vibration state and abrasion degree, and the maintenance decision depends on manual inspection, thus being difficult to realize predictive maintenance and being easy to cause serious consequences such as copper pipe leakage, equipment failure and the like due to local abrasion expansion. In order to solve the technical problems, a condenser copper pipe fixing device which does not need external energy and can synchronously realize shape rebound and abrasion self-repairing needs to be developed, and the self-repairing material is driven to release and the memory alloy is triggered by phase change by creatively utilizing mechanical kinetic energy generated by vibration, so that a vibration-energy conversion-cooperative repairing closed-loop mechanism is formed, the vibration resistance and abrasion resistance of the fixing device are fundamentally improved, the operation and maintenance convenience is improved, and the requirements of high-efficiency, stable and long-period operation of a condenser are met.
