Embodiment
Following content be in conjunction with concrete preferred implementation to further describing that the present invention did, can not assert that concrete enforcement of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
The invention provides a kind of diesel-driven helical-lobe compressor fuel saving method, it may further comprise the steps:
S1: the operating pressure of setting pressure switch and reseat pressure;
S2: regulate adjustable orifice, set the unloading tank pressure;
S3: as user during without gas, system pressure can raise gradually, and system pressure reaches the pressure switch operating pressure, and the pressure switch action must be established solenoid valve by cable and opened, and system forces low pressure unloading operation;
S4: line pressure descends when the user recovers usefulness gas, and during to the pressure switch reseat pressure of setting, the solenoid valve dead electricity is closed, the normal operating pressure of the fast quick-recovery of system.
See also Fig. 1 and Fig. 2, the invention provides a kind of diesel-driven oil-saving system of screw compressor, described diesel-driven oil-saving system of screw compressor comprises solenoid valve 11, pressure switch 12, adjustable orifice 13, fixing frame 14, pressure is regulated mouth 15, minimum tank pressure regulation knob 16 and interface 17,18,19.Described solenoid valve 11 and adjustable orifice 13 are placed on the fixing frame 14, described pressure switch 12 is in parallel with described solenoid valve 11, and control the action of described solenoid valve 11 by relay, described adjustable orifice 13 links to each other with the pressure regulator valve outlet by interface 19, described pressure switch 12 links to each other with line pressure by interface 18, and described solenoid valve 11 links to each other with tank pressure by interface 17.
