Before using the equipment, make certain preparation for its use parts and operation environment, and the use of the equipment in the future will be more smooth. The plate heat exchanger also needs such preparations before use, so as to improve its heat exchange efficiency.
2. Before using the plate heat exchanger, the hot side and cold side can be hydraulically tested at 1.25 times of the working pressure respectively, and the pressure can be maintained for 30 minutes. All sealing parts of the equipment can be put into use only when there is no leakage. The test pressure and holding time can also be implemented according to the system regulations, but the test pressure shall not exceed the test pressure value on the product nameplate. It is forbidden to conduct water pressure test for waste water to prevent water from corroding plates.
3. The exhaust valve shall be installed in the plate heat exchanger to remove the air in the medium and prevent the gas from staying in the equipment to reduce the heat transfer efficiency. The connection of the cold and hot medium inlet and outlet pipelines of the plate heat exchanger shall be strictly in accordance with the provisions of the cold and hot medium inlet and outlet directions of the product, and the wrong connection will lose the operation effect or cause accidents.
For the inspection and inspection of the sealing and exhaust valve equipment of the plate heat exchanger, if any use failure of the equipment is found, it can be solved as soon as possible to avoid affecting the later work process.
