Abstract
The invention discloses a method and device for ensuring low-load stable operation of gas supply machines. The method is characterized in that one group of gas supply machines is used for supplying gas for users; when gas load of gas users is lower than lowest gas supply capacity of the gas supply machines, surplus gas is returned to an intake master pipe or washer inlet through a recirculation pipeline connected to a user master pipe, and normal operation of the gas supply machines can be guaranteed. By adding the recirculation pipeline between the user master pipe and the intake master pipe, the surplus gas is returned to the intake master pipe or washer inlet so as to reduce pressure of the user master pipe and to ensure that the gas pressure of user terminals is kept in a safety range. The method and device has the advantages that the gas supply machines with the same specification are adopted, frequent start and stop of the gas supply machines with different specifications can be avoided, workload of production personnel is reduced, the number of specifications of equipment spare parts is greatly decreased, production management is facilitated, and production cost is greatly lowered.
