A guide to the maintenance of silo pumps and pressure vessels

For the long-term stable operation of silo pumps and pressure vessels, we provide professional maintenance support. Daily maintenance should focus on checking seal wear (such as rotary air lock valves, fluidizer seals), pipe blockage (regular cleaning of foreign bodies and agglomeration), air source pressure stability (fluctuation of more than ±5% needs to be calibrated) and dust collector filtration efficiency (exhaust volume must be greater than fan inlet volume). In case of a sudden drop in conveying volume, it is necessary to check the humidity of the material (the recommended moisture content is ≤5%), the bend angle of the pipeline (reduce the sharp bend by 90°) and the sensitivity of the sensor; In the event of a leak, it is necessary to stop the machine immediately to relieve the pressure, replace the aging gasket or tighten the loose bolts.

The pressure vessel body needs to be tested every year, focusing on the inspection of weld cracks and corrosion pits (the depth of >1mm needs to be repaired), and the hydrostatic test is carried out every three years (1.5 times the working pressure for 30 minutes). In addition, the system should be equipped with an intelligent monitoring module to provide real-time feedback on gas-solid ratio, flow rate and pressure parameters to achieve preventive maintenance. We provide customized maintenance solutions, including rapid supply of spare parts, on-site technical guidance and remote diagnostic services, to ensure the efficient operation of customers' equipment throughout its life cycle.
