Roots blower is mainly used in the following aspects in the paper industry:
Moisture absorption system: In the process of papermaking, the pulp needs to be dehydrated and dried, and Roots blower is widely used in the moisture absorption system. It can help the paper dry quickly by generating negative pressure and extracting water from the pulp.
Vacuum adsorption system: Roots blower is used for vacuum adsorption system during paper manufacturing. It firmly adsorbs pulp or paper on the conveying equipment by generating strong negative pressure for subsequent cutting, folding, processing and other processes.
Ventilation and exhaust system: the paper mill needs to maintain proper ventilation and exhaust to ensure the stability and safety of the production environment. Roots blower is used for ventilation and exhaust system. It can effectively circulate air, control humidity, temperature and gas concentration, and provide a good production environment.
Pumping system: In the pulp preparation stage, Roots blower can be used as the power source of the pumping system. It can transport pulp from one processing unit to another, such as from the mixing pool to the paper machine, or from the paper machine to the drying equipment.
Selection of air volume boost of Roots blower of moisture absorption system:
When selecting the air volume and pressure of Roots blower, the following factors shall be comprehensively considered:
Pulp properties: different pulp properties have different requirements for the moisture absorption system. For example, factors such as slurry concentration, viscosity and particle size will affect the required air volume and pressure. Roots blower must be selected according to specific pulp properties.
Moisture absorption speed: the moisture absorption speed determines the required air volume. If rapid moisture absorption is required, larger air volume is usually required to provide sufficient air flow to extract moisture.
Paper size and thickness: The size and thickness of the paper also affect the required air volume and pressure. Larger size and thicker paper requires larger air volume and higher pressure to ensure effective moisture absorption.
Equipment exhaust capacity: Roots blower in moisture absorption system is usually used together with other equipment (such as filter, dryer, etc.). It is necessary to ensure that the air volume and pressure of Roots blower can meet the requirements of the whole system and match the exhaust capacity of other equipment.
Production demand: determine the air volume and pressure according to the production demand of the paper mill. In consideration of production scale, production capacity requirements, paper varieties and other factors, select appropriate Roots blower parameters.
Selection of air volume boost of Roots blower of vacuum adsorption system:
The following factors need to be considered:
Adsorption demand: determine the required air volume and pressure according to the specific application and requirements of the vacuum adsorption system. Understand the type, shape, size, weight and other characteristics of the object to be adsorbed, as well as the required adsorption time and intensity.
System design: design parameters such as pipe length, diameter and layout of vacuum adsorption system shall be considered. Longer pipes and complex layout may require greater air volume and pressure to overcome airflow resistance and maintain a stable vacuum adsorption effect in the whole system.
Vacuum level: select Roots blower according to the required vacuum level. Different applications may require different vacuum levels, such as low vacuum (coarse vacuum), medium vacuum and high vacuum. Accordingly, the required air volume and pressure will vary.
Roots blower capacity: refer to the technical parameters and performance curve provided by Roots blower supplier to identify the appropriate model and specification. Pay attention to the maximum air volume, maximum pressure, speed and other parameters to ensure that Roots blower can meet the requirements of vacuum adsorption system.
Safety factors: consider the safety factors of the system, such as preventing airflow blockage caused by excessive adsorption, overload protection and fault response capability. Select Roots blower with corresponding safety functions and protective measures.
Selection of air volume boosting of Roots blower in pumping system:
The following factors need to be considered:
Pumping demand: determine the required air volume and pressure according to the specific application and requirements of the pumping system. Understand the properties of the medium to be pumped, flow requirements, conveying distance, height difference and other parameters.
Pipeline design: design parameters such as pipe diameter, length and layout of pumping system shall be considered. Longer pipes, large diameters and complex layouts may require greater air volume and pressure to overcome airflow resistance and ensure effective pumping effect.
Pumping distance and height difference: determine the required air volume and pressure according to the actual pumping distance and height difference. Larger pumping distance and height difference will cause greater airflow resistance, so the air volume and pressure shall be increased accordingly.
Medium characteristics: understand the viscosity, concentration, particle size and other characteristics of the pumped medium. Some media may have special requirements on the performance of Roots blower, and appropriate Roots blower shall be selected according to the media characteristics.
Roots blower capacity: refer to the technical parameters and performance curve provided by Roots blower supplier to select the appropriate model and specification. Pay attention to the maximum air volume, maximum pressure, speed and other parameters to ensure that Roots blower can meet the requirements of the pumping system.
Safety factors: consider the safety factors of the system, such as overload protection, prevention of airflow blockage and other functions. Select Roots blower with corresponding safety functions and protective measures.
Based on the above factors, through careful evaluation and analysis, we can select the appropriate air volume and pressure of Roots blower. At the same time, communication and consultation with Roots blower suppliers to obtain professional advice and technical support will help ensure the best choice and meet the needs of the pumping system.
