High pressure fan in the choose and buy, which need to pay attention to the problems in the process of selection and installation

　　The choose and buy

　　Due to the use of the high pressure fan is very extensive, and the selection of it is relatively complex; Lots of fan brands in the domestic market, so customers when high pressure fan of choose and buy, must pay attention to the following:

　　Supplier of 1, the simple understanding of the strength of the scale, the registered capital, scope of business, the company is to obtain the necessary certificates.

　　2, suppliers, business background, historical performance and growth: the company's action is legal, specification.

　　3, the reliability of the products, quality assurance, perfect after-sales service: products have passed CE certification, RoSH certification, SGS certification and so on.

　　4, whether logistics in a timely manner, the terms of payment, etc

　　The selection

　　Due to the use of the high pressure fan is very extensive, the selection of because it is relatively complex. In general, need according to the following two steps:

　　1, need to determine what is the use of high pressure fan, suction or blowing, find the pressure and flow of high-pressure blower corresponding curve; If the wrong curve, sometimes cause selected products cannot be used;

　　2, according to the calculated pressure and flow rate, pressure and flow on the graph at the same time satisfy the corresponding working point above the working curve; Then according to the working curve choose high pressure fan model;

　　The installation

　　1, must use the flat washer and spring washer to tightening screw;

　　2, it is best to use rubber cushion to withstand the weight of the high pressure fan, especially high power high pressure fan, essential;

　　3, the noise has asked for some occasions, also equipped with muffler to reduce noise (in general, about 5 db), silencer installed in the ventilation pipe or out at the end of the wind pipe;

　　4, requiring high for some to noise, can according to the conditions of the machine itself, plus deadened the noise of a layer of cotton, can satisfy the requirement of the field noise, specific can inquire the manufacturer of high pressure fan or the noise of the professional management company;

　　5, in the use of sound deadened the noise of continous, pay attention to the distance of the high pressure fan and casing, pay attention to the high pressure fan ventilation and heat dissipation, pay attention to the rubber cushion to withstand the weight of the high pressure fan, specific need to consult the manufacturer of high pressure fan, such as high pressure fan gauri, Siemens, etc.;

　　6, high pressure fan into the outlet pipe connection, the hose should be used, to isolate vibration.
