Check or replace the gasket. In the case of the same heat exchange area, the heat exchange loss of the plate heat exchanger is only 1 to 5 of the shell-and-tube heat exchanger, and the weight is less than half of the shell-and-tube heat exchanger. This can greatly increase the thermal efficiency and improve the economics of the heat exchange equipment. Plate heat exchangers are widely used. In the process of heating, cooling, evaporation, condensation, waste heat recovery, etc.
There is a rolling device above the pressing plate, which can easily open the equipment for cleaning and take out a plate.Plate heat exchangers have advantages over other ordinary heat exchangers. On the other hand, the adaptability is also reflected in its use. Both the heat transfer plate and the movable pressing plate are hung on the beam of the machine. At present, they are widely used in various engineering fields such as chemical engineering, machinery, cement, petroleum, electric power, and hot water heating..
Highly adaptable On the one hand, when assembling the heat exchanger, it is convenient to increase or decrease the heat transfer plates according to the output and process requirements, or to rearrange the plates and reselect the process combination. When designing, they must meet the following four requirements: (1) Small temperature difference Because plate heat exchangers have high heat transfer coefficients and strong turbulence, they must After the flow heat exchange in the heat exchanger, the temperature difference between the primary and secondary hot water of the heat exchanger can be very small, and sometimes the temperature difference can approach 1 ℃ ~ 3 ℃.
(2) Small heat loss Because the edge of the plate and the surrounding gasket are exposed to Plate Heat Exchangers FHC014B the atmosphere, the heat loss is very small, generally about 1%, and no insulation measures are required., the purpose of application is achieved through heat exchange between the media in the plate heat exchanger. (4) Flexible operation and convenient maintenance

The plate heat exchanger will also have some problems of one kind or another during use, such as the problems of fouling or water leakage in the heat exchange equipment. The pressure test of overlapping heat exchanger joints can be performed on a single unit.The simple definition of a plate heat exchanger is a device that transfers heat from one heat transfer medium to another. So how to deal with the leakage of plate heat exchanger? Let’s understand it together~
(1) The main reason for the first aspect is that the plate heat exchanger has insufficient clamping dimensions, which can easily cause the heat exchanger to seepage because of uneven dimensions or clamping. It is likely that there is dirt on the main sealing surface of the gasket, the gasket is damaged or the gasket is aging. When each heat exchanger is connected, the tube side and shell side pressure test should be carried out after overlapping assembly.
(3) Of course, some plate heat exchangers have plate leakage, deformation, and assembly misalignment that sometimes cause running pads during use. The liquid inside can easily flow out when it is loose.. The tube side pressure test, and finally the shell side pressure test. For the kettle type reboilers, they should be equipped with a special shell for tube head pressure testing. Floating head heat exchangers and kettle reboilers (floating head tube bundles) are first used to test the pressure of the tube heads with test pressure rings and special tools for floating heads. Plate cracking often occurs in the plate sealing groove or the second sealing area, which are the main reasons for the leakage of the plate heat exchanger.
U-shaped tube heat exchanger, kettle reboiler (U-shaped tube bundle) and stuffing box heat exchanger are used for shell side pressure test with test pressure ring, while checking the joints, and then tube side pressure test. How to check the quality of the heat exchanger at work is a very important issue. (2) Some of the gaskets are out of the sealing groove. If you are interested, let’s take a look~ Fixed tube-sheet heat exchangers HVAC Brazed Plate Heat transfer first perform a shell-side pressure test, and at the same time check the heat exchange tubes and tube sheets Connect the joints, and then perform a pipe stroke pressure test

When the heat exchanger is driven, Heat exchanger company fluid is now filled into the container, the inlet is closed, and the hot fluid problem is slowly injected to minimize the difference in thermal expansion between the tube and the heat exchanger housing formed by the introduction tube. After the heat exchanger is shut down, all fluid in the heat exchanger will be removed by dry compressed air, thereby minimizing stress and avoiding stress corrosion. During driving, the upper and lower water valves are kept fully open to avoid slowing down the flow rate, and impurities in the medium are deposited on the heat exchanger tubular surface to cause corrosion after scaling.
In order to improve the working stability of the heat exchanger hydraulic system, the system should be operated at an appropriate temperature and maintain thermal balance. Using a heat exchanger to control the oil temperature not only ensures the normal operation of the system, but also reduces the thermal deformation of the equipment. Improve equipment working accuracy. If the hydraulic system depends on cooling, the temperature of the oil cannot be restricted below the allowable value. A heat exchanger must be installed; on the contrary, if the ambient temperature is too low to allow the hydraulic pump to move normally, a heat exchanger must be installed.
Easy to clean. I hope our introduction can be helpful to you. Under the premise of using the same data, since the layout requires less data, the production cost must be lower than that of the shell and tube heat exchanger.What are the advantages of plate heat exchangers? In fact, the main reasons for its popularity are its convenient cleaning, light weight, small footprint, and low price. The fluid passing through these bypasses does not fully participate in heat exchange
Reduce the thickness of the plate The design thickness of the plate has nothing to do with its corrosion resistance, but is related to the pressure bearing capacity of the heat exchanger. The geometric structure of the plate corrugation is related to the flow state of the medium. The corners of the plates and the edge sealing structure have been gradually improved, so that the heat exchanger has a good performance. Thicker plates can improve the pressure bearing capacity of the heat exchanger.. The waveform of the plate includes herringbone, straight, spherical and so on.

Water pump failure phenomenon and judgment: After ignition, the water temperature rises too fast or overheating protection, first judge whether the automatic exhaust valve is open, open the front flat screw to see whether the pump shaft is rotating, and use a flat screwdriver to help rotate when it is not rotating. It is impossible to check whether there is 220V electricity on the water pump, if there is, the water pump is broken. The automatic exhaust valve is leaking, disassemble and reassemble, and apply detergent or neutral edible oil on the O-ring to easily install it back.
