气源设备安装
Installation of gas source equipment
气源设备是气力输送系统的动力核心,常见的气源设备有罗茨风机、离心风机等。安装罗茨风机时,要确保风机基础水平,采用减震垫等措施减少风机运行时的振动和噪音。按照说明书要求正确连接进风口和出风口管道,保证管道与风机接口处密封良好,防止漏气影响系统风压。安装完成后,对风机进行单机试运转,检查风机的转向是否正确、运行是否平稳,测量风机的风压、风量等参数,确保其性能符合设计要求。
The air source equipment is the power core of the pneumatic conveying system, and common air source equipment includes Roots blowers, centrifugal blowers, etc. When installing Roots blower, it is necessary to ensure that the foundation of the blower is level, and measures such as shock absorbers should be taken to reduce the vibration and noise during the operation of the blower. Connect the inlet and outlet pipes correctly according to the instructions, ensuring good sealing at the interface between the pipes and the fan to prevent air leakage from affecting the system air pressure. After installation, perform a single machine test run on the fan to check whether the fan's direction is correct and running smoothly. Measure the fan's parameters such as air pressure and volume to ensure that its performance meets the design requirements.
输送管道安装
Installation of conveying pipelines
输送管道的安装是气力输送系统安装的关键环节。首先,根据设计图纸确定管道的走向和位置,使用支架、吊架等固定装置将管道牢固安装。管道安装应保持一定的坡度,便于物料顺利输送,避免出现物料堆积现象。管道连接时,采用焊接、法兰连接或快装连接等方式,确保连接紧密、密封良好。对于焊接连接,要保证焊缝质量,避免出现气孔、裂纹等缺陷;法兰连接时,要使用密封垫片,并均匀拧紧螺栓,防止漏气。安装过程中,要注意管道的清洁,避免杂物进入管道影响物料输送。
The installation of conveying pipelines is a crucial step in the installation of pneumatic conveying systems. Firstly, determine the direction and position of the pipeline according to the design drawings, and firmly install the pipeline using fixed devices such as brackets and hangers. Pipeline installation should maintain a certain slope to facilitate smooth material transportation and avoid material accumulation. When connecting pipelines, welding, flange connection, or quick installation connection should be used to ensure a tight connection and good sealing. For welding connections, it is necessary to ensure the quality of the weld seam and avoid defects such as porosity and cracks; When connecting flanges, use sealing gaskets and tighten bolts evenly to prevent air leakage. During the installation process, attention should be paid to the cleanliness of the pipeline to avoid debris entering the pipeline and affecting material transportation.
分离器与除尘器安装
Installation of separators and dust collectors
分离器用于将输送的物料与空气分离,常见的分离器有旋风分离器、布袋分离器等。安装旋风分离器时,要确保其垂直度,保证物料能够顺利分离和排出。连接分离器与管道时,接口处要密封严密,防止物料泄漏。布袋分离器安装时,要正确安装布袋,确保布袋与箱体密封良好,避免出现漏气影响除尘效果。除尘器用于净化输送后的空气,安装除尘器时,要按照说明书要求安装过滤元件,如滤袋、滤芯等,并定期检查其清洁程度和使用寿命,及时进行更换和维护。
Separators are used to separate conveyed materials from air. Common separators include cyclone separators, bag separators, etc. When installing a cyclone separator, ensure its verticality to ensure smooth separation and discharge of materials. When connecting the separator to the pipeline, the interface should be tightly sealed to prevent material leakage. When installing the bag separator, the bag should be installed correctly to ensure good sealing between the bag and the box, and to avoid air leakage that may affect the dust removal effect. Dust collectors are used to purify the air after transportation. When installing the dust collector, filter elements such as filter bags and filter cartridges should be installed according to the instructions, and their cleanliness and service life should be checked regularly. Replacement and maintenance should be carried out in a timely manner.
控制系统安装
Installation of control system
气力输送系统的控制系统实现对设备的自动化控制和监测。安装控制系统时,要正确连接各种传感器、控制器和执行机构,如压力传感器、流量传感器、电动阀门等。将传感器安装在合适的位置,确保能够准确监测系统的运行参数,如风压、风量、物料流量等。控制器和控制柜要安装在干燥、通风良好的地方,便于操作和维护。连接电线和电缆时,要按照电气原理图进行接线,确保接线正确、牢固,避免出现短路、断路等电气故障。
The control system of the pneumatic conveying system realizes the automation control and monitoring of the equipment. When installing a control system, it is necessary to correctly connect various sensors, controllers, and actuators, such as pressure sensors, flow sensors, electric valves, etc. Install sensors in appropriate locations to ensure accurate monitoring of system operating parameters such as air pressure, air volume, material flow rate, etc. The controller and control cabinet should be installed in a dry and well ventilated place for easy operation and maintenance. When connecting wires and cables, follow the electrical schematic to ensure correct and secure wiring, and avoid electrical faults such as short circuits and open circuits.
