进口多级离心风机Product description:

The sealing coaxiality measuring device of the casing includes a dial indicator, a dummy shaft and two adjusting mechanisms. The dial indicator seat is adsorbed on the dummy shaft, and the two adjusting mechanisms are symmetrically arranged along the longitudinal centerline of the dummy shaft. The adjusting mechanism includes a base, two vertical guide plates, two opposite studs, a support plate, a bearing seat, a bearing and a sleeve with fasteners. The middle of the vertical guide plate is provided with a guide groove, One end of the opposite direction stud is set at the lower part of the support plate and connected with the support plate by threads, the other end of the opposite direction stud is connected with the base by threads, the bearing seat is fixed on the support plate, the sleeve with fasteners is connected with the bearing, and one end of the dummy shaft is sleeved in the sleeve with fasteners and fixed by fasteners. The design is ingenious, the manufacture is simple and convenient, and the sealing effect of the fixed flow passage of the rotary impeller and the casing is guaranteed, so as to improve the working efficiency and service life of the multistage centrifugal fan.

进口多级离心风机characteristic:

Basic working process of multistage centrifugal fan: multistage centrifugal fan is mainly composed of casing containing multistage flow passage and rotor part containing multistage impeller and main shaft; The medium gas is introduced into the impeller inlet from the air inlet chamber; The pressure and speed of the medium gas passing through each stage of impeller are improved by rotating the impeller (blade) at each stage to do work; The gas flowing out of the impeller is further pressurized through the diffuser, bend and reflux; The medium gas discharged from the last stage diffuser is collected through the exhaust chamber and led to the external gas pipeline. The higher air flow velocity is reduced to the air flow velocity at the outlet of the exhaust chamber, which further increases the gas pressure and meets the technical requirements of the fan. The design and manufacturing accuracy of fan casing will directly affect the overall quality of the fan. For multistage centrifugal fan, the sealing effect of each stage rotating impeller and casing fixed flow passage is extremely demanding, which directly determines the working efficiency and working life of the fan. The sealing effect of the rotating impeller and the fixed flow passage of the casing shall meet the relevant technical requirements, and the precondition is to ensure that the concentricity of the flow passage seals at all levels of the casing and the rotor part meet the requirements.

进口多级离心风机Principle:

When using, determine the axis of the rotor part by measuring any two fixed flow channels of the multistage centrifugal fan, adjust the position of the dummy shaft through the adjustment mechanism, so that the axis line of the dummy shaft is collinear with the axis line of the rotor part, push the dial indicator head on a stage sealing seat of the casing of the multistage centrifugal fan, rotate the dummy shaft, and measure the coaxiality of the casing flow channel seals and the rotor part, In the same step, the coaxiality of the casing channel seals and the rotor can be measured; And modify and adjust the parts where the coaxiality cannot meet the relevant technical requirements.
