Principle of energy saving and air tightness test for spiral plate heat exchanger
When it comes to spiral plate heat exchanger, there will be surface type, regenerative type, direct contact type, fluid connection indirect heat transfer mode. In other words, on its own, it's an energy saving device at different temperatures; Helical plate heat exchanger itself is an energy saving device which can realize the heat transfer between materials at different temperatures between two or more fluids.
And the spiral plate heat exchanger equipment is used, that is, the heat will be transferred from the higher fluid to the lower fluid temperature, the fluid temperature to meet the requirements of the process, in order to meet the needs of the process conditions, and at the same time is one of the main equipment to improve energy efficiency.
Speaking of the spiral plate heat exchanger industry, murphy's team found through the investigation, itself will involve hvac, pressure vessels, water treatment equipment and other nearly 30 industries, forming an industrial chain. In order to increase the heat transfer rate of the heat exchanger equipment, in the design, we should fully consider the thermal resistance, after that is to pay attention to the appropriate expansion of the heat transfer area, to meet the heat transfer requirements, but also to achieve the role of energy saving and emission reduction.
Speaking of the principle of air-tightness test of spiral plate heat exchanger, in order to prevent the air-tightness medium of tube heat exchanger from entering the low pressure system, it is necessary to pay attention to the air-tightness test from the low pressure system at this time; When gas tight, two or more pressure gauges must be used to indicate, and the range of the pressure gauge should be more than 1.1 times the test pressure. In order to protect the heat exchanger equipment of the non-boost monitoring pressure gauge, before the boost, that is to pay attention to close the gauge pressure tube.
Spiral-plate heat exchanger air-tightness test principle, in this system of orifice differential pressure meter, when the test should be the valve of the two pressure pipeline open evenly; When there is a check valve on the airtight system, pressure should be applied from the upstream side of the check valve on the helical plate heat exchanger equipment.
