Abstract
The utility model provides a diesel-saving device for a screw compressor driven by a diesel engine. The diesel-saving device includes an electromagnetic valve, a pressure switch, an adjustable orifice and a fixed rack; the electromagnetic valve and the adjustable orifice are arranged on the fixed rack; and the pressure switch is connected in parallel to the electromagnetic valve and controls the action of the electromagnetic valve through a relay. The device can adjust the opening extent of the orifice through adjustment, so as to reduce the unloading tank pressure; and the machine set can run under the lower unloading tank pressure, so that the power of the diesel engine can be greatly reduced during the unloading operation, and the diesel-saving effect is very remarkable.
Description
Technical field
The utility model relates to a kind of mechanical field, particularly about a kind of diesel-driven helical-lobe compressor gasoline-saving device.
Background technique
Diesel-driven compressor bank tolerance regulative mode major part all is to adopt air inlet restriction and diesel engine speed to regulate dual mode and usefulness, and pressure regulator valve or similar device action when present stage, to be rotational speed regulation or air inlet restriction all be higher than rated pressure by unit pressure, the control gas that forms certain pressure goes to adjust the aperture of rotating speed or suction valve.
Because unit unloading runtime system pressure is higher than rated pressure, cause the unit operation back pressure too high, and unit under higher back pressure, unload the operation the result be, even unit is when carrying out unloading without air supply operation, the fuel consumption rate of unit still maintains high level, therefore, there is the uneconomic defective of operation in existing technology.
The model utility content
In order to overcome above-mentioned the deficiencies in the prior art, the utility model provides a kind of oil-saving effect good diesel-driven helical-lobe compressor gasoline-saving device.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of diesel-driven helical-lobe compressor gasoline-saving device is provided, it comprises solenoid valve, pressure switch, adjustable orifice and fixing frame, described solenoid valve and adjustable orifice are placed on the fixing frame, described pressure switch is in parallel with this solenoid valve, and controls the action of this solenoid valve by relay.
The scheme of the further technical solution problem of the utility model is: it further comprises first interface, second interface and the 3rd interface.
The scheme of the further technical solution problem of the utility model is: described adjustable orifice links to each other with the pressure regulator valve outlet by the 3rd interface.
The scheme of the further technical solution problem of the utility model is: described pressure switch links to each other with line pressure by second interface.
The scheme of the further technical solution problem of the utility model is: described solenoid valve links to each other with tank pressure by first interface.
The scheme of the further technical solution problem of the utility model is: it further comprises pressure adjusting mouth and minimum tank pressure regulation knob.
The scheme of the further technical solution problem of the utility model is: described pressure is regulated mouth and minimum tank pressure regulation knob is placed on the pressure switch.
Compared to prior art, the advantage of the diesel-driven helical-lobe compressor gasoline-saving device of the utility model is: this device is by adjusting the adjustable orifice aperture, thereby reduce the unloading tank pressure, because unit is worked under lower unloading tank pressure, so diesel engine power in the time of can reducing the unloading operation greatly has very significantly oil-saving effect.Rated working pressure is 10～14bar (1bar=10
5Pa) movable compressor uses this gasoline-saving device, during unloading than the compressor fuel-economizing 10～15% of not adorning this gasoline-saving device; Rated working pressure is that the movable compressor of 17～24bar uses this gasoline-saving device, during unloading than the compressor fuel-economizing 20～30% of not adorning this gasoline-saving device.

Embodiment
Following content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
See also Fig. 1 and Fig. 2, the utility model provides a kind of diesel-driven helical-lobe compressor gasoline-saving device, described diesel-driven helical-lobe compressor gasoline-saving device 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 this solenoid valve 11, and control the action of this 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.
Described pressure is regulated mouth 15 and minimum tank pressure regulation knob 16 is placed on the pressure switch 12.
During practical work process, pressure switch 12 setting pressures are that (ft lbf is (1bf/in2) per square inch for the rated pressure+10psi of system, 1psi=6894.76pa), as user during without gas, system pressure can raise gradually, system pressure reaches pressure switch 12 (P) operating pressure, and switch motion must be established solenoid valve 11 (YV1) by cable and opened, and system forces low pressure unloading operation; Regulate adjustable orifice S, set the unloading tank pressure, the unloading tank pressure can be adjusted between rated pressure and pressure minimum valve opening pressure as requested.Since can be the unloading tank pressure regulation to more much lower than rated pressure, the fuel consumption rate during the unloading operation can reduce significantly.Line pressure descends when the user recovers usefulness gas, during to the pressure switch reseat pressure of setting, and closed electromagnetic valve, the normal operating pressure of the fast quick-recovery of system.
The beneficial effects of the utility model are: this device is by adjusting the adjustable orifice aperture, thereby reduce the unloading tank pressure, because unit is worked under lower unloading tank pressure, so diesel engine power in the time of can greatly reducing the unloading operation has very significantly oil-saving effect. Rated operating pressure is 10～14bar (1bar=105Pa) movable compressor uses this petroleum economizer, during unloading than the compressor fuel-economizing 10～15% that does not fill this petroleum economizer; Rated operating pressure is that the movable compressor of 17～24bar uses this petroleum economizer, during unloading than the compressor fuel-economizing 20～30% that does not fill this petroleum economizer.
