hot water centrifugal boiler feed water pump

Boilers must build on their strengths and avoid weaknesses if they want to develop

At this stage, with the dual development of economy and science and technology, in the domestic boiler market, the development of boiler can be described as a rising day, and the main reason is the high efficiency and safety of the boiler itself, and so on. Safety and efficiency are issues that industry will consider when choosing boilers. But if the boiler wants to develop better, must be able to carry on the strong point to avoid the weakness.

From a structural point of view, the condenser by a screw shape form consisting of smoke tube arrangement, the outer plates of the tube, using embossed aluminum packaging, together constitute a three condenser.

1, a plasma cutting machine for cutting sheet metal processing, cutting speed is 5 times normal oxygen cutting method, while sheet impact is small, does not cause scratches, thermal deformation. Intelligent CNC technology makes the operation more flexible.

2, threaded smoke tube increased as compared with ordinary light pipe 5 much heat transfer area, heat faster, while meeting the needs reducing the overall heat transfer area of ​​use.

3, when welding between the threaded pipe and tube sheet, using Expansion -> Welding -> then Expansion (corrective action), and both were face to face welded to ensure that, compared to other boiler manufacturers use welding point larger heat transfer area and higher heat transfer efficiency.

4, of course, can not give condenser thermal insulation, selecting more expensive square fast, better insulation advanced centrifugal glass cotton, weld gap portion is filled sufficiently to ensure that the heat will not be lost.

Concern the 2014 APEC summit (referred to as APEC), held in Beijing Huairou Yanqi ecological demonstration zones on November 10, multinational leaders are to attend an important meeting. The summit venue construction attaches great importance to environmental protection work. In selecting venues hot water centrifugal boiler feed water pump heating and hot water services, to the summit to make clear that emissions of nitrogen oxides boiler, perform extremely strict NOx emission standards around the venue --60 mg / cubic meter. Carefully selected, nitrogen oxide emissions technology in the international advanced level of fast Boiler become the ultimate winner. Gas hot water boiler fast boiler developed the production of ultra-low nitrogen oxide emissions, gas steam boiler, integrated condensing boiler has become the summit heating and hot water designated products.

Introduction to four problems of selecting and purchasing condensing hot water centrifugal boiler feed water pump!

As a new favorite of the new era, condensing boiler is not only more efficient but also environmentally friendly than ordinary gas-fired boiler. It is more and more popular with us, especially for large-family houses. However, many people are not familiar with condensing boilers, daily shopping will often encounter the following 4 major problems, let's take a look.

1, are all household sizes suitable for the installation of condensation wall hangers? Condensing boiler companies ranked top company introduction: in home applications, for only half a hundred square meters or so of the household type, is also suitable for the installation of condensation wall hanging furnace? This may be a false proposition, but the fact is that some heating companies "across-the-board" promote condensation wall hanging furnace, regardless of the size of the owner, this cost-effective account is variable, so this is a need for our specific issues specific analysis.

2, is the whole premixed must be better than the secondary heat transfer condensation? Many people in the industry will sniff at the secondary heat transfer condensing furnace as "false condensation", but the warm cube notes that the secondary heat transfer condensing heat efficiency is also more than 100%, belonging to the category of first-class energy efficiency, but the overall thermal efficiency is a few points lower than the full premix.

3, is it possible for any company to install condensing furnaces? Is it the same as installing conventional wall hanging stoves, can any company install condensation furnaces without professional training, what are the differences in installation, post-maintenance and repair aspects of condensing furnaces? when selecting and purchasing boilers, attention should be paid to manufacturers. Whether the industry organization has a supporting training or evaluation or certification system, when we select the condensing boiler company, we all need to consider these points.

4. Why are condensing boilers so much more expensive than conventional boilers? The price of condensing boilers has become the biggest obstacle to the promotion of almost every HVAC company. Looking at the current market, almost all brands of fully premixed condensing furnaces are more expensive than conventional boiler markets. Where is this expensive? Still, the question is, is your initial cost and post-maintenance cost, whether or not all household areas, all usage habits and conditions, can recover the expensive costs, and when choosing, you should look at the price list of the condensing boiler company, and for the owner, it is necessary to look at the price list of the condensing boiler company. It has made a great contribution to the national "energy saving and emission reduction".

Boiler Feed Water Pumps & Condensate Pumps | Boiler Supplies

Large industrial condensate pumps may also serve as the feedwater pump. In either case, to force the water into the boiler, the pump must generate sufficient pressure to overcome the steam pressure developed by the boiler. This is usually accomplished through the use of a centrifugal pump.
