Installation Of Plate Heat Exchanger

In order to make the plate heat exchanger give full play to the good use effect, more efforts should be made in the installation before use, and the installation work should be done properly to ensure the smooth use of the equipment in the future. It's necessary to install it correctly.

1. Foundation acceptance: Before installing the heat exchanger, check whether the general situation, plane position, shape and size of the foundation surface and the reserved holes meet the actual requirements, whether the position of the anchor bolts is correct, whether the nuts and washers are complete, and observe whether the threads are in good condition; Whether the foundation surface on which the shim is placed is flat, etc.

2, unpacking inspection equipment.

3. According to the equipment installation dimensions given in the installation drawing, make the foundation platform and arrange the anchor bolts;

4. When moving and transporting, avoid violent collision and damage to the plate;

5. Before installation, check and clean the pipeline sundries to prevent sundries from entering the plate heat exchanger and blocking the flow passage; Connect the pipeline correspondingly, and install thermometer and pressure gauge on the pipeline near the heat exchanger, which is convenient for checking the operation of the heat exchanger;

6. Place the shim: Place the shim on the foundation before installing the plate heat exchanger. In order to make the two contact well, it needs to be leveled.

7, check the clamping stud, if there is any looseness, tighten and reduce the parallelism deviation between the two clamping plates;

8. Unless there are special requirements in the process, generally, the valve of the cold medium at the side that needs to be heated or cooled should be opened first, and then the valve of the medium at the side of the heat source or cold source should be slowly opened after its normal flow;

9. According to the import and export temperature and pressure data, open and start the relevant valves in a proper position to maintain a stable working state;

10, in normal use, should often record the temperature and pressure state parameters, check the equipment working condition; Check the sealing position of plate heat exchanger frequently, observe whether there is leakage and take measures such as pressure relief and clamping;

11, the use of corrosive, flammable medium, it is recommended to add thin iron sheet protection devices on both sides of the plate bundle;

12, plate cleaning can be washed with water or chemical cleaning agent, soft brush should be used.

13. Leveling and alignment: After installation, level the heat exchanger, so that all nozzles can be connected to the pipeline without stress.

How to install the plate heat exchanger effectively is more important for use. Therefore, more attention should be paid to the installation, and it should be operated by professional personnel as far as possible, so that it can not only be installed correctly, but also avoid damage to the equipment.
