The design thickness of the plate has nothing to do

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. Because the corrugation of the plate heat exchanger can cause the fluid to produce turbulence at a small flow rate (Reynolds number-150), it can obtain a Heat Exchangers FHC052G Exporters higher surface heat transfer coefficient.2

Ways to reduce the resistance of the heat exchanger   Increase the average flow velocity of the medium in the inter-plate runner, which can increase the heat transfer coefficient and reduce the area of ​​the heat exchanger. On the premise of meeting the pressure bearing capacity of the heat exchanger, the thickness of the plate should be as small as possible.1 Improve heat transfer efficiency.  2.

Therefore, care must be taken to monitor the water quality on both sides of the heat exchanger to prevent fouling of the plates and prevent debris in the water from adhering to the plates. After years of research and experimentation, it has been found that the corrugated cross-sectional shape is triangular (sine-shaped surface heat transfer coefficient is the largest, the pressure drop is small, the stress distribution is uniform under pressure, but the processing is difficult?) Herringbone plates have higher surface transmission Thermal coefficient, and the greater the angle of the corrugation, the higher the flow velocity of the medium in the flow channel between the plates, and the greater the surface heat transfer coefficient. 

 ④ Set heat exchanger bypass pipe    When the flow of cold and heat medium is relatively large, a bypass pipe can be installed between the inlet and outlet of the heat exchanger on the large flow side to reduce the flow into the heat exchanger and reduce resistance. Improve the surface heat transfer coefficient of the plate. The maximum pressure capacity of the domestic detachable plate heat exchanger has reached 2. It is not economical to increase the flow rate to obtain a slightly higher heat transfer coefficient.  ⑤ Selection of the form of the plate heat exchanger

This is not easy during the use process

This is not easy during the use process. After disassembling the plate heat exchanger, it was found that the surface of the cold fluid end of the plate was bright, with a small amount of black dirt in some parts, the number of corrosion pits was small and did not penetrate, and there were black deposits in the corrosion pit, so it can be inferred to be a gasket Sheet corrosion exists. When the plate heat exchanger is used within the rated working pressure,

the leakage is mainly related to the abnormal impact load of water hammer and air hammer in the system, in addition to the quality factors of the equipment in the manufacturing and assembly. Manufactured (with a thickness of 0. Let’s take a look at the plate heat exchanger as follows~    mainly has the following ways:    rubber gasket material in contact with fluid, when a fluid component penetrates into the rubber, sometimes the soluble substances in it can be extracted, resulting in the production of rubber gaskets

Because some parts of the plate heat exchanger layout need to be welded, there will be a large residual stress during the production process, which provides a prerequisite for stress corrosion. For example, austenitic stainless steel is prone to stress corrosion in a neutral chloride solution, but only the quality concentration of oxygen in the medium is less than 1. Therefore, welding operations must strictly abide by irrelevant welding regulations. Some systems have a critical fracture potential, which will cause corrosion and fracture. Stopping the heat treatment of cold-worked parts and welded parts can help eliminate residual stresses, which also helps prevent stress corrosion.

he heating area is about Heat Exchangers FHC052G Exporters. In addition, the plate heat exchanger bears lower working pressure.  Plate heat exchanger only has the outer shell plate of the heat transfer plate exposed to the atmosphere, therefore, the heat dissipation loss is negligible and no insulation measures are required.6Mpa. For the shell-and-tube heat exchanger, when the liquid processing capacity needs to be increased, the heat transfer area of ​​the original heat exchanger cannot be increased, but the plate heat exchanger The heat transfer area of ​​the heat exchanger is easily increased, thereby increasing the processing capacity

Turn on the heat exchanger and clean the plate

What is the reason for this? Interested friends follow the plate heat exchanger manufacturers to take a look~   Cause analysis:   1, internal blockage;   2, flow trough blockage;   3, the wrong placement of the plate causes side flow;   4, the medium viscosity is strong circulation (flow ) Slower;   5. Solution:   1, disassemble the heat exchanger to clean the interior;   2, disassemble the interface to clean the outlet;   3, rearrange the plates;   4, re-select or adjust the working conditions;   5, remove non-condensed gas;  

 6, remove Turn on the heat exchanger and clean the plate to change the plate arrangement;   7, change the flow rate or requirements;   8, remove the gas and replace the condensate discharge valve or the air pump to replace the steam control valve;   9, modify the system.   Hope that the introduction of plate heat exchanger manufacturers can be helpful to you, follow us for more news! If you don’t understand those aspects, you can consult us and we will have professionals to answer you!.The heat exchange efficiency of the plate heat exchanger is low, and sometimes the effect is not obvious when it is used.

When steam condenses, the high pressure drop is affected by the presence of non-condensed gas;   6, plate fouling;   7, side flow caused by incorrect placement of the plate;   8, the actual data is different from the calibration data;   9, There is a discrepancy between the flow rate and the calibration value;   10. There is a problem stainless steel hanging furnace with the system design. The failure during condensation can be caused by the following reasons: non-condensed gas, too low steam dryness, condensing steam arch valve or too low weather, steam control valve failure;   11, there is gas in the heat exchanger; 12

Even if there is a leakage, the medium will always be discharged. According to the heat exchange area in the unit space How much, the plate heat exchanger is a compact heat exchanger, mainly compared with the shell-and-tube heat exchanger, the traditional shell-and-tube heat exchanger occupies a larger area.

Make the side with the smaller heat transfer coefficient

Every user wants to refrigeration heat exchanger a product that is helpful to them, and the same is true for plate heat exchangers. If you want to choose a product that suits you, you should understand its main points. Let’s take a look at the seven choices of lower plate heat exchangers. Main points~   1.

The control parameters of the plate heat exchanger are heat exchanger material, working pressure, design temperature, etc.  2. The fluid containing silt and dirt should be filtered and then enter the heat exchanger.  3. When the plate heat exchanger is selected, the flow velocity at the interface of the fluid on the side with the smaller temperature difference should not be too large, and it should be able to meet the pressure drop requirements.  

4. When selecting a heat exchanger, try to make the side with the smaller heat transfer coefficient get a larger flow rate, and try to make the heat transfer coefficients on both sides of the two fluid heat exchange surfaces equal or similar to improve the heat transfer coefficient.  5. For the case of large flow rate and low pressure drop, the plate type with low resistance should be selected, otherwise, the plate type with large resistance should be selected.  6

. ​​According to the fluid pressure and temperature, select the detachable type or the electric welding type.  7. It is not advisable to choose plates with too small veneer area, so as to avoid too many plates, the flow velocity between plates is too small, and the heat transfer coefficient is reduced. Nowadays, many of my friends are buying plate heat exchanger products, but the use effect is not ideal. Then everyone knows what causes this situation? Next, our plate heat exchanger customer service, let’s give you a brief introduction Take a moment.   1.

Reasons for system configuration. Plate heat exchangers only play a role in heat conversion and follow the law of energy conduction, that is, the heat released by the hot side is equal to the heat absorbed by the cold side.

The heat pipe of the heat exchanger is under negative pressure

Heat pipe heat exchanger is a new type of heat exchanger with high heat transfer efficiency, which is widely used in aerospace, electronic chemical engineering, petrochemical industry and electric power industry. The heat pipe heat exchanger is mainly composed of three parts: a heat transfer element heat pipe, a box supporting the heat pipe, and a partition plate that divides the flow channel. The heat exchanger partition divides the entire tube box into two parts, one side is the evaporation section of the heat pipe, flowing through the hot gas; the other side is the condensation section of the heat pipe

, flowing through the cold gas. The heat pipe of the heat exchanger is under negative pressure. During operation, the medium in the evaporating pipe section evaporates quickly due to heat, and flows to the condensing section through the small pressure difference on both sides of the heat pipe. Under the action of force, the liquid flows back to the evaporative endothermic section along the porous material inside the heat pipe, and the cycle is repeated to complete the endothermic and exothermic processes. Usually the heat pipe of the heat exchanger is welded with fins to enhance heat exchange. The heat pipes on both sides of the heat exchanger separator can be individually set to length and fining ratio according to the temperature, cleanliness, flow rate, etc. of the cold and hot fluids.

The tubular heat exchanger is composed of several tubes, and the tube diameter varies from 10 to 15 mm to 120 to 150 mm. Generally installed in the flue, it can be placed vertically or horizontally. Air (or gas) flows inside the pipe, and exhaust gas flows outside the pipe. Occasionally, the opposite occurs.

The air water to water heat exchanger company enters the heat exchanger tubes through the heat exchanger cold air box, is heated after several reciprocating strokes, and is finally sent out through the hot air box. In order to avoid heating and bending of the tubes, each tube of the heat exchanger should not be too long. When the temperature of the exhaust gas is below 700 ~ 750C, the air can be preheated to below 300 ℃, if the temperature is too high, the tube is easily deformed, and the weld seam is cracked. This type of heat exchanger has the advantages of simple structure and good air tightness. It can not only preheat air but also preheat gas. The disadvantage is that the preheating temperature is low, and the ordinary steel pipe is easy to deform and leak, and the life of this heat exchanger is short.
