The 150 type Roots blower is a volumetric rotary blower with the characteristic of forced gas transmission, widely used in various fields such as sewage treatment, powder conveying, aquaculture, pneumatic conveying, cement production, mine ventilation, and grain processing. The following is a detailed introduction to the 150 type Roots blower:
1、 Performance parameters
1. Air volume: The general air volume range is between 10.39~27.05m3/min or 10.8~24.8m3/min, depending on the design and application scenario of the fan. Some specially designed or customized fans may have more specific airflow values, such as 17.2~39.3m3/min, etc.
2. Wind pressure: The discharge pressure is usually between 0.1~0.6MPa or 9.8kPa~58.8kPa.
3. Speed: The speed range is usually between 1150 and 1900rpm.
4. Power: The power range is between 15~37kW, and there is also a 75kW 150 model Roots blower available for selection.
Structural Features
1. Rotor design: The rotor of the 150 type Roots blower is usually designed with special features to ensure good stability and wear resistance during high-speed operation.
2. Bearings and Seals: High quality bearings and seals are used to ensure the stability and reliability of the wind turbine during long-term operation.
3. Shell material: The shell is usually made of high-quality steel with sufficient strength and stiffness to withstand various stresses generated during operation.
3、 Advantages of use
1. Energy saving: Adopting advanced pneumatic design and manufacturing processes, it has energy-saving characteristics and can significantly reduce energy consumption.
2. Low noise: Emphasis is placed on noise control during design, optimizing the structure and using low-noise materials to reduce the noise generated by the fan during operation, meeting environmental requirements.
3. Easy to maintain: The structure is compact, simple, and very easy to maintain. High quality components also extend their maintenance cycle and reduce maintenance costs for users.
4、 Precautions for use
1. Inlet temperature: The inlet temperature should not exceed 40 ℃.
2. Gas quality: The solid particle content in the gas should not exceed 100mg/m3, and the particle size should not exceed half of the assembly gap.
3. Bearing temperature: The bearing temperature should not exceed 95 ℃.
4. Lubricating oil temperature: The lubricating oil temperature should not exceed 65 ℃.
5. Preparation before startup: Before startup, check the installation quality of all fasteners and locating pins, as well as the installation quality of intake and exhaust pipes, valves, etc., to ensure that the base of the unit is firmly padded around, and anchor bolts should be tightened. At the same time, the specified grade of lubricating oil should be injected into the gearbox to the oil mark position, and the specified amount of lubricating grease should be injected into the drive side with sufficient quantity.
6. Empty load test run: Newly installed or overhauled fans should undergo empty load test run, which refers to putting them into operation with the intake and exhaust valves open. Run with no load for about 30 minutes. If the situation is normal, you can start running with load.
5、 Maintenance and repair
1. Regular inspection: Check the fastening condition of each part and whether the positioning pin is loose. Regularly inspect the body for oil leakage, pay attention to whether the lubrication is normal, and pay attention to the amount of lubricating grease.
2. Replace lubricating oil: The lubricating oil is medium load industrial gear oil (grade 220, kinematic viscosity 198-242mm ²/s @ 40 ℃, flash point ≥ 200 ℃); The grease is butter (synthetic lithium based grease needle penetration, drip point ≥ 190 ℃). Run for 200 hours, change the oil and grease once, and change the oil and grease for the second time after running for a month. In the future, it is recommended to replace it every three months according to the usage environment and oil (grease) quality condition.
3. Clean the filter: Regularly check the air inlet gas filter and promptly clean or replace the filter element.
4. Precautions for disassembly and assembly: Before disassembling the machine, the dimensions assigned to the machine should be measured, recorded, and marked on the components to ensure that the original fit requirements are maintained after assembly.
6、 Market situation
There are several well-known manufacturers in the market that produce 150 type Roots blowers, such as the Changsheng brand, with stable product performance and reliable quality. The price varies depending on factors such as brand, configuration, and performance.
