The Rectifier is ready for use before use
What are the preparations for the Rectifier before use? Under normal conditions, the pressure difference between the inlet and outlet of the Rectifier is determined and verified to determine whether the tube housing is available. When the tube appears to leak, probably quickly check the tube is not damaged, once discovered, it is necessary to quickly repair.
Due to heat transfer tube in the operation of the violent sensation to form a leak, it should be necessary to stop and timely repair.
In the usual use of the process will probably do the time to open the Rectifier at both ends of the head, the box, the tube in time the body of foreign bodies and the appearance of the stolen goods clean and clean.
Regularly view the Rectifier of the two covers, the official box is not corrosive, rust, cracks and trachoma and other conditions, once discovered and timely repair.
Timing on the Rectifier control and shell pressure test, leak test, check the bolt tightness, good insulation, anti-corrosion method (if necessary, to be part of the test).
The regulation should also be scheduled to check the heat transfer tube is not a deformation and twists and turns of the situation.
Check the corrosion status of the baffle and baffle and the tie rod bolts.
Check the sealing surface of the Rectifier to ensure that the sealing surface without scratches, pits.
In the normal operation of the Rectifier, but also on the tube and tube welding at the color inspection.
Many of the equipment will produce a lot of heat, long-term so that the machine's life is shortened, so people often need to use the Rectifier to cool the equipment, the common Rectifier gas Rectifier and liquid Rectifier.
The working principle of the plate Rectifier is as follows:
Since the chilled water (refrigerant fluid) is not in direct contact with the circulating cooling water (working fluid), the heat of the circulating cooling water is transferred to the chilled water by the heat exchanger, and the temperature of the circulating cooling water at the higher temperature is reduced Low temperature fluid, when the heat exchanger on both sides of the fluid for the constant temperature heat transfer, it includes three processes:
The first process: the circulation of cooling water (working fluid) flow of heat transfer to the heat transfer film on the wall of the convective heat transfer process; the second process: through the heat transfer film heat transfer process; the third process: The heat exchanger on the other side conveys the heat transfer to the chilled water (refrigerant fluid).
