The plate heat exchanger is a kind of heat exchange equipment with high efficiency and low price. It has low investment cost, low installation cost, low maintenance and cleaning cost, flexible applicability, and is also a very energy-saving and environmentally friendly equipment.
The plate heat exchanger needs to pay attention to some problems during the installation process. Otherwise, it will affect the performance of the plate heat exchanger and cannot achieve the expected heat transfer effect.
(1)The plate heat exchanger has four lifting lugs for use during lifting. The slings cannot be directly tied to the plate group, the beam and the guide bar.
(2) When the plate heat exchanger is installed, it needs to maintain 1 m of maintenance space to facilitate the phe cleaning and maintenance in the future.
(3)The thermometer and pressure gauge should be equipped on the pipeline.
(4) If the medium to be walked by the plate heat exchanger is turbid or has large particles, it is necessary to configure a filter valve on the inlet pipe.
(5)Before the formal operation, the plate heat exchanger pipe should be cleaned. If the welding slag or sand enters the heat exchanger, it will cause blockage of the heat exchanger and affect the heat transfer effect.
(6)When connecting the heat exchanger to the pipeline, the ground wire of the welding should be placed at the welding place, and the ground wire should not be placed in the distance to prevent the current loop and damage the heat exchanger.
(7)Ensure that the plate heat exchanger is within the normal clamping dimensions.
(8)If the operating temperature of the heat exchanger is above 100 degrees, take over the expansion and absorption compensation device with thermal stress.
