Fans can be divided into low pressure fans, medium pressure fans, and high pressure fans by pressure.
Backing plate installation: In order to prevent damage to the fan, two sets of backing irons must be arranged at each anchor bolt distributed around the installation.
In the sewage treatment process, the energy consumption of the blower aeration system accounts for more than half of the energy consumption of the entire process system. The use of air suspension centrifugal blowers can achieve the effect of saving electricity and saving costs.
What are the characteristics of a blast furnace blower? Blast air is supplied to the blast furnace to ensure the coke and oxygen required for the injected fuel in the blast furnace. In addition, there must be a certain wind pressure to overcome the resistance of the air supply system and the material column, and maintain a certain top pressure of the blast furnace.
What to do with the problems in the blower chemical system: common faults: when choosing water cooling, forget to release water during parking in winter, causing frost cracking;
Induction fan of cement kiln is used to discharge dust-containing flue gas in kiln, the temperature is 350-450 ℃. It adopts centrifugal type, and the blade is radial or wing-shaped. The structure should consider wear resistance and high temperature resistance. The air volume is between 9000-12000m³ / min and the wind pressure is between 7000-10000Pa.
Dust removal fan is an important equipment of dust removal system. The role of the dust removal fan is to convey the dust-containing gas to the dust collector and exhaust the purified gas to the atmosphere. Dust removal fan is a type of fan application. Dust removal fan is a centrifugal fan, also called dust removal centrifugal fan. Today, environmental protection is important, and many companies' production workshops will install dust removal equipment to collect and process dust generated during production. In dust removal equipment, fans are used. This type of fan is called dust removal fan. The dust removal equipment is mainly composed of filters, fans and dust collection boxes. Dust-containing air enters the cabinet from the dust source through the suction hood, air duct, and air inlet. Due to the sudden expansion of the air flow, the flow rate suddenly decreases. In the drawer, the remaining dust particles are trapped on the outer wall of the filter element due to the filtering, collision, hooking, and static electricity of the filter element, and the purified air is discharged by the dust removal fan through the outlet. The purified air can be directly discharged into the indoor circulation. Achieved the purpose of environmental protection and dust removal.
The metal mine fan has good reverse air supply performance (that is, easy reverse air), and the return air volume can reach 60% -70% of the air supply volume. Since the metal mine fan can use the reversed wind of the motor, neither a diffuser or a diffusion tower nor a fan room or a backwind duct is required. The construction process is simple, which can greatly shorten the construction period. Compared with other fans, it has fewer auxiliary equipment, fewer control links, good safety and reliability, and can save 70% of civil engineering costs.
What are the characteristics of the blower? During normal operation of the blower, check the bearing temperature, lubricating oil in the fuel tank, motor, etc. every 1 to 2 hours. The temperature should not be higher than the specified value. Roots blowers are very noisy when running. In order to reduce noise, in addition to installing a silencer, you can also use some simple methods to reduce noise, such as the crypt method.
The use of V-belt drive faces this problem. How to calculate the difference between the speed of the Roots fan and the speed of the motor? It can be calculated by the following formula: motor speed * motor speed = fan speed * fan speed. It is not difficult to see from this formula that as long as the size of the roots fan pulley is constant, and the speed of the roots fan can be checked from the manual through the requirements of flow and pressure parameters, the speed of the roots fan is also fixed, and the speed of the motor is Constant, then it is easy to calculate the size of the motor pulley. Roots fan speed should be selected to reduce the speed as much as possible to meet the technical parameters of flow and pressure to achieve the purpose of extending service life.
