maintenance of nitrogen generator
oxygen generator equipment maintenance, establish correct maintenance concept and pay enough attention to maintenance. good operation habits and regular maintenance can prolong the normal service life of the equipment, reduce energy consumption, reduce maintenance cost, effectively avoid sudden faults and greatly reduce the negative impact of faults on production
o precautions for daily use
o
o 1. normal supply and normal opening and closing of power supply, water source, air source and temperature conditions required by the machine; especially for the stability of power supply voltage, a voltage regulator can be installed when necessary to reduce the damage to the controller and solenoid valve caused by power supply problems.
o
o 2. pay attention to the air volume, temperature and pressure at the inlet of the cold dryer at any time, and keep the evaporation pressure of the cold dryer between 0.4 ~ 0.5 mpa, not exceeding the rated pressure.
o
o 3. check the automatic blowdown valve of the filter and the automatic drain of the cold dryer every day to avoid blocking and losing the function of drainage and blowdown.
o
o 4. regularly check whether the heat sink of the cold dryer is clean every week, so as not to affect the utility and service life of the dryer doer to poor heat dissipation.
o
o 5. carry out operation and routine maintenance according to the requirements of instrument use code, and irregularly check the sensitivity of solenoid valve / pneumatic valve, pressure range of pressure regulating valve, accuracy of gas analyzer, compression of adsorption tower, exhaust condition of muffler, cleanliness of inner pipe of flowmeter, etc.
o
o 6. check the heating components, electrical control system, hydrogenation capacity, regeneration gas flow of drying tower and regeneration temperature and time of purification equipment.
o
o spare parts replacement schedule
o
o fitting name
o replacement time
o
o pipe filter element
o 6 months or the differential pressure gauge pointer points to the red area
o
o fine filter element
o 12 months or the differential pressure gauge pointer points to the red area
o
o ultra fine filter element
o 18 months or the differential pressure gauge pointer points to the red area
o
