First unpacking check the negative pressure fan parts in the transport has been deformed or damaged, if this situation should be corrected before the installation can be used.
1, open the junction box, turn on the power supply operation (no load), the direction of rotation of the impeller and the same nameplate arrow, negative pressure fan housing to be grounded and observe whether the shell, if this situation should be adjusted immediately.
2, negative pressure fan wiring flange should be connected to the canvas or other soft to take over, in order to facilitate the FRP fan and pipe vibration isolation, FRP fan should not love the weight of the external duct, roof-type FRP fan and the base connection and split hood Install the connection should be added vibration pad, and add a sealant to avoid air leakage.
3, negative pressure fan installed in place, all fasteners must be re-tightened once.
4, to be clear negative pressure fan inlet and outlet pipes and all nearby obstacles can be put into use after the official.
Over the past year, China's fan industry has undergone an extraordinary development process. In the face of international and domestic economic situation, the development of the industry has been challenged. Facts show that the opportunities we face are no longer a traditional opportunity to simply integrate into the global division of labor system, expand exports and speed up investment, but how to grasp and adapt to independent innovation, economic development and other new historical opportunities.
China's fan industry has great potential for development, enterprises in the production and product design technology level of continuous progress in recent years, further step into the automation to increase efficiency and competitiveness, but in the face of opportunities also accompanied by great challenges, and now infrastructure, Factories and mines, residential and other fields to the fan industry to put forward higher requirements, such as large infrastructure projects now less domestic equipment with fans.
Although China's fan industry to the rapid pace of development, showing a rapid growth trend, but there are also some unavoidable problems,
At present, China's fan industry's problems mainly in the following three aspects:
1、uneven industrial structure,
2、the lack of core competitiveness,
3、improper competition within the industry.
China's economy is now in the process of transition, the new technology has not yet found the outbreak point, in this trend of the fan industry is facing industry rebalancing and structural transformation of the pressure. Faced with this situation, China's fan industry should be calm, calm, and actively respond to the maximum to meet the needs of the industry, so that the future development of the domestic fan industry better
Gear pump because of their increasingly important role, the industry's development plan is the goal of scientific research and development investment. With the rapid development of science and technology in the 21st century, gear pumps will be the same as the mobile phone to intelligent.
Gear pump industry focus on key research and development projects have been the industry's various companies attach great importance to the most important is reflected in three aspects: First, the nuclear power plant equipment technology research is to carry out the main pump pump ap1000 core technology research, two On behalf of the technology 1000 core pump main pump technology research, nuclear two, three nuclear pump hub technology research, millions of kilowatts of pressurized water reactor nuclear power pump technology research and nuclear power pump technology scale research; the second aspect, The technical research of petrochemical hub equipment includes the development of million tons of pta device with screw pump, gear oil pump, high pressure small flow pump, quench oil pump hub technology research; the third aspect is to carry out the pump energy saving mechanism research. The next few years, gear oil pump development plan is the goal of scientific research and development investment in pump manufacturing industry, the proportion of GDP to more than 6%, pump manufacturing technology to improve the contribution rate of 68%, to promote the modern equipment manufacturing industry as the core Construction of Vertical Water Pump Manufacturing Industry.
In today's rapid development of science and technology in the 21st century, the gear pump manufacturers have to improve their technological level, so that the gear pump gradually toward the direction of intelligent development, to a certain extent, the valve products and industry development has also been promoted effect. Botou a pump with the trend of science and technology, so that the technical content of oil pump products and shape design has been greatly improved to improve the gear pump market competitiveness, so that a pump in the market have a place.
High-pressure whirlpool fan as a daily production and life commonly used in a device, then the pump routine maintenance work can not be ignored. If only do not pay attention to maintenance, then it may cause the machine to shorten the service life, and even more likely to affect the smooth progress of other work, so Xiaobian today to share with you about the whirlpool pump maintenance matters, only familiar with these, To make the pump better for us to work.
Maintenance of proper maintenance is the whirlpool fan life long premise
First, before using the whirlpool pump, make sure to place it on a smooth ground, and make sure that the surrounding environment is clean and dry and ventilated because the air pump is in the process of working, the motor will send a lot of heat, if not placed in Dry and not ventilated environment, easy to damage the air pump motor, because the temperature will gradually increase; Secondly, in the whirlpool pump work process, to ensure that the working pressure shall not be greater than the fan rated parameters, because too high pressure may make the motor High load operation, the huge heat generated by the pump and the motor too high current, may lead to damage to the pump. Third, because the use of air pump material is mainly aluminum, but small parts are made of iron, so prohibit the operation of the process, to prohibit the solid, liquid, gas and other corrosive substances into the pump, which will cause the whirlpool pump Major parts are damaged.
Then the last, that is, do not use the whirlpool pump, it should be placed in a dry environment, so as to prevent the internal parts of the rust, while the regular maintenance of its timely replacement of which parts are not suitable, So that the machine can better serve the enterprise, only the conservation of good, in order to ensure its efficiency and quality, but also for the production of enterprises to save a lot of capital costs.
Also in the purchase of high-pressure fan, do not be confused by low-cost fans, many small domestic manufacturers, in order to obtain more benefits in the production process using some poor raw materials and so good, so easy to make the machine Serious quality problems, so in the purchase process must be compared between the products, find inexpensive products.
First; factory direct vortex blower, fan motor direct impeller and are high speed, the bearing needs to add butter regularly maintenance, to prevent damage (including impeller bearings).
Second, the motor shaft power and pressure is proportional to the long-term limit pressure to prevent shaft power increases, the motor load is too heavy, often use the relief valve, it is a discharge valve, when the pressure of the use of high pressure fan After the pressure set by the relief valve, the relief valve will automatically open, the excess pressure released, thus protecting the high-pressure fan motor.
Third; whirlpool blower internal institutions are relatively close, impeller and chassis clearance is very small, so to filter debris and dust. Usually in the air inlet with a fine filter / filter. It is based on different use of the site, often using different filter filters
Fourth, in some special occasions, also need to carry out special protection: For example, in the use of sealed environment, pay attention to ventilation and heat; when the ambient temperature (intake air temperature is relatively high), but also pay attention to ventilation and cooling, or select Allows the whirlpool blower with higher inlet air temperature.
