The difference between plate replacement machine and casing machine, which is better, plate replacem

The difference between the plate changing machine and the casing machine is: different hot water control, different accessories, and different water discharge speeds.

First, the hot water control is different.

1. Plate changer: The priority operation of domestic hot water of plate changer is controlled by the start and stop of the water pump.

2. Casing machine: The priority operation of the domestic hot water of the casing machine is controlled by the electric three-way valve.

Second, the accessories are different.

1. Plate exchanger: The plate exchanger has an electric three-way valve and a separate domestic hot water heat exchanger.

2. Casing machine: The casing machine does not have an electric three-way valve and a separate domestic hot water heat exchanger.

Third, the water speed is different.

1. Plate replacement: The anti-impact ability of the plate replacement machine is better, and the hot water output speed is faster.

2. Casing machine: It takes a long time for the casing machine to heat and convert domestic hot water, and the water output speed is slow.

The main difference is that the heat exchange method of hot water in the bathroom is different, the plate replacement model provides domestic water through secondary heat exchange, and the casing provides hot water through direct heat conduction through the main exchange. Each has its own advantages, the casing machine has better anti-impact, and the hot water output speed is faster; The heat of the plate changing machine is uniform, and the domestic hot water is comfortable to use.

The casing heat exchanger is a tube-in-tube heat exchanger, and the domestic hot water casing is nested in the main heat exchanger, and the domestic hot water is preferred.

The operation is controlled by the start and stop of the pump, and when the domestic hot water is running, the pump stops working and is heated by a high-temperature water in the main heat exchanger.

Domestic hot water inside the casing.

The plate exchange type is used to heat the domestic hot water through a plate heat exchanger, and the domestic hot water is preferentially operated by an electric three-way valve.

When there is a demand for domestic hot water, the electric three-way valve will introduce the primary high-temperature water in the main heat exchanger into the plate to heat the life. Hot water.

Board machines and nesting machines are commonly used in the electronics manufacturing industry for the production and assembly of circuit boards. Despite their similar names, they have different functions and uses.

1.Function: PCB Routing Machine is mainly used for cutting, cutting, and drilling holes in circuit boards.

It uses a cutter or drill to cut the copper wires on the circuit board, creating or separating circuit paths. The PCB punching machine is used to strip the processed circuit board from the original board and arrange it to the desired size and shape.

2.Applicable objects: The board machine is mainly suitable for large-scale circuit board cutting and drilling, especially suitable for large-scale nuclear production on the production line. Nesting machines are suitable for small batch production, especially for the production of small circuit boards and custom circuit boards.

3.Operation mode: The board machine usually adopts a computer control system, which can be operated automatically. Lining, on the other hand, can be operated manually, requiring the operator to place and separate the boards precisely as needed.

4.Scope of application: The board machine can be used for a variety of circuit board materials, including rigid and flexible boards. Whereas, the nesting machine is mainly used for the separation and finishing of rigid circuit boards, and is usually suitable for thinner circuit boards.

In general, board machines and board machines differ in function, applicable objects, operation methods and scope of application. The choice of which equipment to use to break the crack is based on the specific operational and production requirements required.

Summary. Hello, I am glad to answer for you, which is a good plate exchange and casing heat exchanger, plate exchange and casing heat exchanger: it is good to change casing.

Casing heat exchanger, also known as composite heat exchanger, commonly known as tube-in-tube heat exchange or large tube casing small tube heat exchange, the small tube that produces hot water is nested in the main heat exchanger, and the tap water flowing in the casing is heated by the high-temperature water (heating water) in the main heat exchanger to provide sanitary hot water. The plate heat exchanger is a stainless steel heat exchanger that is independent of the main heat exchanger, and provides sanitary hot water by exchanging heat between high-temperature water (heating water) and flowing tap water in an external plate heat exchanger.

Hello, I am glad to answer for you, which is a good plate exchange and casing heat exchanger, plate exchange and casing heat exchanger: it is good to change casing. Casing heat exchanger, also known as composite heat exchanger, commonly known as tube-in-tube heat exchange or large tube casing and small tube heat exchange, the small tube for producing hot water is nested in the main heat exchanger, and the tap water flowing in the casing is heated and eliminated through the high-temperature water (heating water) in the main heat exchanger to provide sanitary hot water.

The plate-swap heat exchanger is a stainless steel heat exchanger that is independent of the main heat exchanger, which provides sanitary hot water by interchanging hands with flowing tap water in the external plate heat exchanger (heating water).

Hello Comparison of stool between plate exchange heat exchange wall-hung boiler and casing heat exchange wall-hung boiler: 1The sanitary hot water stability of plate exchange heat exchange is better than that of casing heat exchange.

2.Casing heat exchange is relatively easy to seep and form scale. 3.

Plate heat exchangers have a longer service life than casing heat exchangers. 4.Plate heat exchangers are less expensive to repair and replace than casing heat exchangers.

5.The cost of plate-for-type wall-hung boiler is higher than that of casing wall-hung boiler.

Hello dear Sorry for the typo, it's the plate heat exchanger, oh <>

Whether the boiler casing machine or the plate replacement machine is better, you can choose the one that suits you through the following analysis.

First of all: comparison of heat exchange principles.

Casing machine, also known as pipe-in-pipe, the main heat exchanger is nested with domestic hot water casing, the start and stop of the pump is used to control the priority operation of domestic hot water, when the domestic hot water is running, the pump stops working, and the domestic hot water in the casing is heated by a high-temperature water in the main heat exchanger.

When the system realizes the need for domestic hot water, the electric three-way valve will introduce the primary high-temperature water in the main heat exchanger into the plate to heat the domestic hot water.

Secondly: technology comparison.

1. Comfort of domestic hot water - during the use of the casing machine, if the production hot water is temporarily closed and turned on in a short time, it will easily cause the domestic hot water to be hot and cold, and in severe cases, scalds will occur. This phenomenon does not exist at all, and the use of domestic hot water is both safe and comfortable.

2. Scaling - the scaling situation of the casing machine will be more serious with the precipitation of the use time, and the domestic hot water temperature of the plate replacement machine will be controlled below 60, which is not easy to scale.

3. Service life - when the casing machine is used or temporarily closed, the water in the main heater does not flow, and the waste heat cannot be dissipated in time, which will cause local high temperature and affect the service life.

And finally: the structure is contrasted with **.

The structure and control of the casing machine are relatively simple, and it is relatively cheap.

There are many internal components of the board replacement machine, and it is also relatively expensive.

Teacher, what is the difference between the plate replacement machine and the casing machine wall-hung boiler in real thing?

What is the difference between the plate replacement machine and the casing machine wall-hung boiler in physical objects? Hello dear, the difference lies in the constant temperature of domestic water. The constant temperature effect of the plate change is better.

The casing will appear hot and cold in addition. Limescale will appear on the casing. Affect the service life of the machine.

1. Principle: Although the double casing type has a secondary heat exchange, because the water heater is converted into a boiler, like the ordinary water heater, the flame direct heating exchanger, the gas ratio and the water flow rate cannot be completely matched. The principle of heat exchange is to carry out secondary heat exchange through the secondary heat exchanger to alleviate the contradiction between gas and water flow, but still achieve the purpose of constant temperature by controlling the water flow, so the water flow rate changes 2

The double casing design is in conjunction with the heating main heat exchanger, in the combustion chamber; The plate heat exchanger is designed on the waterway plate outside the combustion chamber; 3. Material: double casing is copper pipe; The plate heat exchanger is stainless steel; The maximum pressure of the casing machine is 6kg, and the maximum pressure of the plate type is 10kg; 4. Scaling: The tap water in the double casing directly absorbs the heat of the main heat exchanger in the furnace, and continues to absorb the heat of the furnace flue gas when the hot water function is not used, which is easy to cause scaling; When the hot water function is not used, the electric three-way valve switches back to the heating state, and the heat of the primary heating water will not continue to bring the tap water in the plate exchange, so it is not easy to scale; 5. Comfort:

Before turning off the faucet and re-opening it, the double-sleeved tube type is easy to continue to absorb heat, and the temperature rises greatly, resulting in overheating of the water temperature when the faucet is reopened during use; The stainless steel plate heat exchange is completely external, which will not be affected by the residual heat of the furnace, and the temperature control is still uniform and stable when the faucet is turned on frequently; 6. Maintenance: The disassembly of the double casing is cumbersome, it is not easy to deal with after scaling, and the maintenance cost is high; The plate heat exchanger is placed externally on the waterway plate, which is easy to disassemble, and the stainless steel material is not easy to scale. Hope it helps.

Teacher, what is the difference between the plate replacement machine and the casing machine wall-hung boiler in real thing?

Teacher, what is the difference between the plate replacement machine and the casing machine wall-hung boiler in real thing? 1. The principle is different: although the double casing type has a secondary heat shock, it is exchanged, but because the water heater is converted into a boiler, like the ordinary water heater, the flame direct heating exchanger, the gas ratio and the water flow rate cannot be completely matched.

The principle of plate exchange heat exchange is to carry out secondary heat exchange through the secondary heat exchanger, which alleviates the contradiction between gas and water flow, but still achieves the purpose of constant temperature by controlling the water flow, so the water flow rate changes. 2. Different forms: the double casing is designed together with the heating main heat exchanger in the combustion chamber.

The plate heat exchanger is designed on the waterway plate outside the combustion chamber. 3. The material is different: the double casing is a copper pipe.

The plate heat exchanger is stainless steel; The maximum pressure of the casing machine is 6kg, and the maximum pressure of the plate type is different in terms of fouling: the tap water in the double casing directly absorbs the heat of the main heat exchanger in the furnace, and continues to absorb the heat of the furnace flue gas when the hot water function is not used, which is easy to cause fouling.

When the hot water function is not used, the electric three-way valve switches back to the heating state, and the heat of the primary heating water will not continue to bring the tap water in the Banming car, so it is not easy to scale. Hope it helps.
