Pay attention to the vibration of the heat exchanger unit

The fluid of the heat exchanger unit generally has a high flow rate. For example, the flow pulsation and transverse flow will cause the fluid induction of the heat exchanger unit. These are generally due to external reasons, such as the failure of the pipeline spring support and hanger conveying the fluid, the loosening of the anchor bolts of the heat exchanger unit, and the unstable supporting foundation of the equipment, which will cause the equipment vibration.

The vibration of the equipment shall be closely monitored, and the vibration value shall be strictly controlled not to exceed 250 μ m。 When this value is exceeded, it needs to be checked and processed immediately.

Especially for those with poor service environment and high requirements, the carbon steel material of heat exchanger unit adopts special R & D and design processes, such as double pass welding and intermediate inspection, which can greatly improve the quality and meet the harsh service requirements. The main products of municipal heat exchange equipment R & D and production include: V series plate, shell and tube, various storage tanks, volumetric, floating coil, spiral plate, air cooler, radiator, water, decontaminator, filter, heat station, etc. The experts of the production plate of the equipment have issued 66 times. Due to resistance, corrosive medium and flow abrasion, especially the fixed tubesheet, but the temperature difference stress, the connection between Tubesheet and heat exchange tube is easy to leak, resulting in failure. Due to some details easily ignored during production, there are common quality problems in the welding of tubesheet and heat exchange tube, Strong corrosion of other water and organic mixtures is also a factor.
