Roots blowers have several sealing forms: The common sealing forms of Roots blowers are packing gland type and expansion ring type. Which type of labyrinth type and mechanical seal is used depends on the nature of the gas (whether it is harmful, whether it can touch grease, whether it is clean, whether it is meaningful or not) depends on it. When compressing gases such as gas, there are usually four sets of such seals between each bearing and the cylinder, and a set of oil seals at the outer end of the shaft. . Pressurized oxygen, ammonia, etc. When , sulfur dioxide, , etc. and grease (fat) cannot contact the air, four sets of mechanical seals are installed in the cylinder penetration part to lubricate the bearing, gear, part, and protect the gas. This configuration promotes a large span of the rotor bearing.

Introduction:
This 50-type Roots blower is a Roots blower with a small diameter. DN50A, this fan is energy-saving (low noise, small size, vibration The start of small power and high pressure is a good start for the Roots blower. The Type 50 Roots blower is easy to operate. If you remove the muffler and motor, you can move it back and forth by yourself. The energy-saving effect of Roots blower series is obvious, which is much more energy-saving than the early two-blade Roots blower.
Roots blower care is included in the user manual. When we apply a Roots blower, please read the Roots blower manual carefully. Today, the blower will focus on several maintenance contents to tell you.
Grease Grease
This content is very important. The fan editor has mentioned it many times. For those who have not read it, you can read this article "Roots Fan Lubricant and Grease Knowledge"
2. Barometer value
When the rated pressure drops, the Roots blower barometer value must exceed the rated pressure. Long-term overpressure of the fan will affect the normal operation of the fan.
3. Temperature monitoring
conducts temperature measurements on these components every day: bearing temperature, housing temperature, fuel tank temperature, inspects and registers daily.
If the temperature is too high, it will seriously damage the fan. When an abnormal fault is found, abnormal noise or temperature will often occur.
Roots blower manufacturer's maintenance and parts replacement standards, based on the preparation of blower failure analysis, determine the location and scale of maintenance, and prepare parts that may need to be replaced. According to the structure of the parts, prepare appropriate Inspection items and measuring instruments. Based on the conditions of the blower, an overhaul plan was developed. Implement measures. When disassembling precautions, the size and equipment location of key components should be marked so that they can be reselected and marked during the assembly process to facilitate failure. For example, measure the thickness of various gaskets and and write it down, measure the clearance of each component of the rotor and write it down, and check according to the corresponding marks on the main gear, driven gear and tooth space.
Roots blower does not require lubrication during use fat. It is easy to use and adopts a three-blade rotor structure and a reasonable shell inlet and vent structure, so the fan has small vibration and low noise. Noise pollution is also well ensured. The fan is sturdy and durable and can operate continuously for a long time. The power used is very high, which can improve our operation and bring benefits to the operation. However, the adjustment of three Roots blower parts also requires attention to maintenance. The fan rotor is one of the parts that has been used for a long time in Roots blowers. In order to protect all operational contaminants, we often have to inspect and manufacture them.
