Whether the pneumatic conveying valve can be successfully applied to production, in addition to the design, manufacturing, installation and operation must be very serious, daily maintenance and maintenance are also very important. Especially the pneumatic conveying valve works in a sealed state, many failures Hidden dangers are not easy to detect, which makes the importance of timely repair and maintenance more obvious. Pneumatic conveying valves can be roughly divided into: air source machinery, air pipe, feeder, conveying pipe, branch, separator, unloader, Dust pipe, dust removal system and electric control system. The maintenance points of each part are described as follows:
1. Maintenance of air source machinery
In the pressure-feed pneumatic conveying system, the air source machinery mainly refers to the air compressor and the Roots blower. Because it is conveyed with exhaust gas, there will be no special maintenance problems for the compressed air machinery itself. According to the manufacturer's The product manual can be repaired and maintained according to the requirements of general machinery. In the suction pneumatic conveying system, the water ring vacuum pump and the roots vacuum pump are usually used as the air source machinery. Since the air is used for conveying, once the air is sucked If it contains dust, it will accelerate the wear of the fan and affect the performance of the fan; there may also be dust adhering to the inside of the fan, which will not only reduce the performance of the fan but also generate vibration, and in serious cases will affect the life of the fan. Clean the inside of the fan and remove the adhered dust.Once the blades of the fan are found to be worn, they should be replaced in time to ensure a good operating state.
2. Maintenance of air duct
In the suction pneumatic conveying system, the air pipe refers to the pipeline between the dust collector and the air inlet of the fan and the air outlet of the fan to the hood. Generally speaking, the maintenance of these two parts of the pipeline is not large, but you must pay attention to the sealing of the connection of the air pipe In the situation, always pay attention to whether the air pipe body is rusty. The damage of the air cap will cause the rainwater tank to enter, and it should be repaired in time. In the pressure-feed pneumatic conveying system, the air pipe includes from the gas compressor discharge port to the feeder The air inlet of the (or delivery tank), together with the intermediate air storage tank, gas-water separator, gas supply system and corresponding piping. The air storage tank and the gas-water separator are pressure vessels, and the usage requirements of the pressure vessel should be followed Check its safety regularly, and pay special attention to the accuracy of the safety valve setting pressure. The oil and water accumulated in the gas storage tank and the gas-water separator should be discharged in time.
The above is the maintenance and maintenance of the pneumatic conveying valve shared by our company for you. Welcome to order. Thank you for your support.
