Plate cooler: Key points for assembly and installation of plate coolers

The assembly process of the plate cooler for flat plate refrigeration

Read any document in the article carefully (such as qualification certificates, material certificates, process sheets, cad part drawings, packing lists, etc.).

2. Check whether the materials of the plates, joints and gaskets of the plate cooler are consistent with the anti-corrosion requirements of the substances inside the heat exchanger.

3. Check all the components of the plate cooler against the engineering drawings to ensure they are complete and that the model and specification are in line with the engineering drawings.

4. Clean the gasket grooves of the plate thoroughly, apply the adhesive evenly to the gasket. Then stack the plates neatly together and place a certain amount of hanging objects on them.

5. Assemble in accordance with the process table of the design plan and clamp in the prescribed order. When clamping, pay attention to tightening the nuts in sequence.

6. Hydraulic press tests should be conducted on each side separately.

Common problems and installation points of plate coolers

When lifting the plate cooler, pay attention to the management of the machinery and equipment.

When bonding gaskets, it is necessary to ensure that there is no sand, oil stains, iron pins or flux and other dirt on the gasket and the gasket groove of the plate to prevent damage to the sealing performance and cause leakage.

3. When tightening the anchor bolts, apply force evenly and constantly measure the distance between the inner sides of the two clamping plates to ensure that the flatness error between the two clamping plates does not exceed 3 millimeters. Clamp to the required specification and achieve relative flatness to prevent the washer from being pressed off or sliding out of the washer groove.

4. Water is generally selected as the liquid for hydraulic press experiments. The temperature should not be lower than 5℃, and the pressure should be changed slowly during the experiment.

5. A certain amount of maintenance space should be left around the plate cooler, and its size is related to the specification of the plates.

6. The anchor bolts for clamping should be coated with unsalted grease. When there are standards, they should be covered with maintenance tubes to prevent rust and damage to the external threads.

7. If the maximum working pressure at the inlet and outlet of the pump exceeds the maximum application working pressure of the machine equipment, a pressure regulating valve and a valve need to be installed at the inlet of the plate cooler machine equipment.

8. When the plate cooler machine equipment is filled with liquid and contains working pressure, it is not allowed to hold the nuts.
