What Do Glass Blowers Do?

The blower is mainly composed of the following six parts: the motor, the air filter, the blower body, the air chamber, the base (also the fuel tank), and the drip nozzle. The blower runs eccentrically by the offset rotor in the cylinder, and changes the volume between the blades in the rotor slot to suck air in, compress it, and spit it out. In operation, the pressure difference of the blower is used to automatically send lubrication to the drip nozzle, and drip it into the cylinder to reduce friction and noise, while keeping the gas in the cylinder from flowing back. This type of blower is also called a sliding blade blower.

Fans, blowpipes, and bladders, the earliest devices for forced air blowing

The blower does not need lubrication because the impeller runs in the body without friction.

Rotor: by shaft,

How centrifugal blowers work

The operator must be familiar with this regulation before starting up, and operate the blower strictly according to this regulation.

1. Check the oil level of the oil tank. It should be between the oil dipstick and the lower limit.

2. Notify the substation to supply power to the machine.

3. Check the control cabinet on the machine. There should be no alarm display. If there is an alarm, the cause should be eliminated.

4. Select "Manual" status. (Touch the "Manual" key with your finger).

5. Check whether the pressure relief valve is in the open position (the pressure relief valve opens and the green light is on). Check that the diffuser is set to the minimum opening (minimum green light of the diffuser is on).

6. After the above checks, after confirming that the fan can be started, press the start key, and the fan enters the startup program: The auxiliary oil pump is pre-lubricated for one minute (the green light of the auxiliary oil pump runs). The blower can start running (the green light of the blower is on).

The pressure relief valve is closed slowly (the pressure relief valve is turned off and the green light is off, and the pressure relief valve is turned off and the green light is on after two minutes).

The auxiliary oil pump stops running (the green light of the auxiliary oil pump goes out and the red light stops). At this point, the blower has been successfully started and can be put into formal operation.

If the blower fails to start as expected after pressing the start key, the red alarm light turns on after a minute when the oil pressure is too low, and the entire starting process stops. After the cause has been found out, the alarm must be cleared and restarted.

1. After the fan is started, the opening of the diffuser can be slowly adjusted according to the production needs, and controlled by the "open" and "close" keys of the diffuser to ensure the necessary air volume.

2. When the fan is running, the fan must be monitored frequently. Pay attention to the fan current, oil temperature, oil pressure, vacuum pressure, sound, fan, temperature, vibration, etc. Make records on time. If there is any abnormality, find out the cause in time and eliminate it, and report to the production section. If necessary, take emergency stop measures (use with caution).

When a fan is stopped due to production or maintenance or maintenance.

1. Reduce the opening of the diffuser to the minimum (the minimum indicator of the diffuser is green).

2. Touch the "Stop" button of the fan with your finger, and the shutdown program will start:

The blower is mainly composed of the following six parts: motor, air filter, blower body,

Fan energy saving transformation

At present, motors supporting fans in various types of machinery and electrical equipment in various industries in China account for about 60% of the national installed capacity of motors and consume about one-third of the country's total power generation. It is particularly worth mentioning that most fans have the phenomenon of large carts during use. In addition, due to changes in production and technology, it is necessary to constantly adjust the flow, pressure, and temperature of the gas; many units still use them. A backward way to adjust the degree of opening of the air baffle or valve to adjust the flow, pressure, temperature, etc. of the gas. This is actually to meet the requirements of the gas flow regulation of the process and working conditions at the cost of wasted electricity and money by artificially increasing the resistance. This backward adjustment method not only wastes precious energy, but also has poor adjustment accuracy, and it is difficult to meet the requirements of modern industrial production and services. The negative effects are very serious.

In recent years, with the rapid development of power electronics technology, computer technology, and automatic control technology, electrical transmission technology is facing a historical revolution, that is, AC speed regulation has replaced DC speed regulation and computer digital control technology has replaced analog control technology. trend. Motor AC frequency conversion speed regulation technology is a major means to save power, improve process flow to improve product quality and environment, and promote technological progress.
