Precautions for operation of plate heat exchanger

Plate heat exchanger is used more and more widely nowadays. As a common heat exchange equipment, it realizes the exchange of heat. The correct operation of the heat exchanger is an important aspect of realizing its use function, because incorrect operation will not only prevent the equipment from running, but also affect the normal use of the equipment.
1. At the beginning of operation, if the plate heat exchanger is found to have uneven cooling and heating, check whether the air is not completely discharged, whether the heat exchange plates are wrongly added, and whether they are usually blocked, and take corresponding effective measures.
2. If two media are found to be interlinked, especially flammable and explosive media, stop the machine immediately, find out and replace the perforated or cracked plates.
3. Strictly control the temperature and pressure not to exceed the allowable value, otherwise the aging of sealing gasket will be accelerated. As the equipment is full of media during operation, it is not allowed to firmly clamp the bolts under pressure.
4. When tightening the clamping bolts and nuts of the heat exchange plate, the plate bundle distance between the two heads should be strictly controlled, otherwise the heat exchange plate or sealing gasket will be easily damaged. The sliding roller on the movable head of the heat exchanger shall be oiled regularly to prevent rust, so as to ensure flexible disassembly and easy use.
5. Avoid operators from riding, stepping on and placing objects on the plate heat exchanger to avoid damage due to operation errors.
6. During startup, shutdown and operation, the operation procedures shall be strictly followed, and abnormal operation is prohibited.
7. During operation, always pay attention to the changes of temperature and pressure, and avoid overheating and overpressure operation, so as not to affect safe use.
The operation process of plate heat exchanger also needs constant inspection and observation to ensure the uniform heat exchange of equipment. Meanwhile, proper ventilation measures shall be taken during use to prevent heat loss. You need to know the correct operation method and be able to master it.

Hydrostatic test of plate heat exchanger

The plate heat exchanger has a strong heat exchange effect, and we need to add some media, such as water, to achieve the heat exchange effect we want when using it. In order to improve the heat exchange effect, we will also do some small experiments before official use, and we can also do some related heat exchange through hydraulic test. So how should we do well in hydraulic test?
1. Check whether the clamping size meets the drawing requirements.
2. Fill with water or other fluid and exhaust air.
3. Install the blind plate.
4. Connect the pressure test pump or other manual pressure test device to the plate heat exchanger.
5. It is qualified if there is no leakage at 1.25 times of the design pressure and one side alternately pressurizes and maintains pressure for 30min. However, special attention shall be paid to the following: the pressure shall rise slowly and evenly to the required index during pressurization.
6. Install air tightness tester at the inlet and outlet and connect the compressed air source.
7. Close the inlet and outlet valves and open the side funnel.
8. Pressurize the plate heat exchanger and keep it for a period of time according to the specification requirements, and observe the change of air pressure.
9. According to the test results, judge whether the required airtight performance standards are met.
During the hydrostatic test of plate heat exchanger, excess air must be discharged and filled with water to ensure accurate measurement results. Hydrostatic test can reflect the heat exchange efficiency of equipment to a certain extent. If the water pressure of the equipment meets the requirements, it can indicate that the hydraulic test has been successful. At this time, we can continue to use the equipment. It seems that the hydraulic test is very important.

Quality requirements for heat exchanger plates

The heat exchange of heat exchanger is very strong. When purchasing, attention should be paid to the selection of process and flow channel, because these two factors will also affect the equipment to a certain extent. We bought it mainly to achieve efficient heat exchange function. Since plates are so important to the whole equipment, we should know the requirements of plate quality. So what is the requirement? Before the production of plates, let's see what the quality requirements are? At that time, the production of plates will be completed according to the quality requirements.
1. Pits, scratches, indentation and other defects that exceed the thickness tolerance are not allowed on the surface, and the punching burr shall be removed.
2. The forming thinning amount of heat exchanger shall not be greater than 30% of the original actual plate thickness.
3. The parallelism of the base plane in any direction shall not be greater than 3/1000mm.
4. The deviation of ripple depth of heat exchanger shall not be greater than 0.20mm, and the deviation of gasket groove depth shall not be greater than 0.20mm.
5. The roughness of the working surface of the plates used in the food industry after stamping shall not be lower than that of the original plates.
6. The plate surface after plate making shall be flat and smooth without visible unevenness or wave shape. Generally speaking, the error of surface flatness should not exceed 1/5 of the plate thickness.
For the quality requirements of heat exchanger plates, we need to know some basic requirements in the process of producing plates. Under normal circumstances, if the produced plates can meet the above requirements, the quality is acceptable, and they can be used in various heat exchange equipment to play a good role in heat exchange. The quality of plates is related to the future heat exchange, so please complete the production of plates in strict accordance with the quality requirements.

Replacement steps of rubber parts of heat exchanger

The maintenance of the heat exchanger is simple, and many people think it is easy to use. However, after a long time of use, the performance of most equipment will decline, which is inevitable. At this time, we need to replace the equipment parts. How to replace rubber parts?
1. Inspection and testing of recycling performance. Check the wall thickness of the heat exchanger and pipes when rust is suspected.
2. Clean the aging seals. According to different dirt, the acid and alkali cleaning pool is used for chemical cleaning, and the surface of the parts to be cleaned will not be corroded by chemical media.
3. Each plate shall be coated with fluorescent testing agent, inspected for small cracks and corrosion holes under ultraviolet light, and cleaned again. In addition, the condition of the sealing groove shall be checked emphatically, and it shall be trimmed if necessary.
4. After chemical cleaning. Clean the residual chemical medium on the surface with high-pressure blowing device
5. For adhesive sealing gasket, clean up the residual substances, use the mixed adhesive to re bond, and clamp the reassembled heat exchanger plate group in the special fixture to solidify the adhesive; Heat in the holding furnace to achieve good bonding effect. For non adhesive gaskets, different devices are used to fix the gaskets in the heat sink.
6. Inspect the bonding position and bonding quality of each plate radiator, classify them according to the installation sequence, and then carefully assemble the plate radiator group.
The heat exchanger has many advantages, but it is still necessary to carry out regular inspection and maintenance of the equipment in the process of use, so as to avoid unnecessary wear and tear of the equipment if the problems of the equipment cannot be solved in time. Rubber parts shall be replaced at any time to prevent the use of equipment from being affected.
