heat exchanger tube bundle cleaning

This technology uses the cavitation effect and the principle of cavitation in the fluid mechanics to complete the cleaning of the special hard dirt on the inner wall of the pipeline. When the liquid from the rear of the pipeline cleaning device push the process forward, before and after the pipeline cleaning device produces pressure difference and flow from the crack of the spring sheet, rubber sheet through cause leaf spring and vibration frequency, violent shaking, cleaning device is this whirling vortex surrounded, forming a continuous movement of the low pressure area, the area of water has always been a gaseous state, the resulting subtle steam soak and quickly is compressed until it burst and transient lasing a powerful micro jet, numerous micro jet converging shock wave, shattering sediments. The structure of pipeline cleaning device takes into account the annular gap formed between the outer surface and the inner surface of the tube. When the liquid flows through the annular gap (10-15m/s) at high speed, the dirt will be sent to the 8-10m before the cleaning device. As the liquid running faster than the pipeline cleaning device 1.5-2 times faster, dirt is always in front of the equipment movement until the discharge, but not for the occurrence of clogging. Pipeline cleaning device to 0.4-1.2m/s speed, after the pressure 0.6-1.2MPa (6-12 kg force /cm2) to transfer liquid along the pipeline running, through their own discharge of liquid 25-40%. Its cleaning rate is determined in the transport of water consumption, strong scarring degree and cleaning device before and after water pressure differences, the slope of the Guan Daoqing, distance from the outfall of the distance.
