Abstract
The invention relates to environment-friendly urban bus gas circuit control equipment, which comprises a pressure switch, a high-voltage relay, a direct current (DC)/alternating current (AC) conversion circuit, an air compressor and a power supply, wherein the power supply is connected with the DC/AC conversion circuit; the DC/AC conversion circuit, a contact of the high-voltage relay, the air compressor and the DC/AC conversion circuit are connected in series in turn to form a loop; one end of a coil of the high-voltage relay is connected with the pressure switch and the other end of the coil of the high-voltage relay is grounded. The control device also comprises a normally open solenoid valve, wherein one end of an electromagnetic coil of the normally open solenoid valve is connected with the pressure switch and the other end of the electromagnetic coil of the normally open solenoid valve is grounded; and a valve body of the normally open solenoid valve is arranged at an outlet of the air compressor. Compared with the prior art, the equipment has the advantages that: the air compressor is protected, the air compressor is prevented from polluting a power supply of the whole vehicle during on-load starting, and the like.
Description
Technical field
The present invention relates to a kind of bus gas circuit control setup, especially relate to a kind of environment-friendly type city bus gas circuit control convenience.
Background technology
Pure electric bus is owing to replaced Traditional engine with drive motor; Just must increase electric air compressor uses the gas demand to satisfy car load braking, ABS etc.; But because car load factory is unreasonable to the design of Air compressor control policy now; Make the Air compressor loaded starting, had a strong impact on the service life of Air compressor, also brought hidden danger to vehicle driving safety.
Summary of the invention
The object of the invention is exactly for the defective that overcomes above-mentioned prior art existence a kind of environment-friendly type city bus gas circuit control convenience to be provided.
The object of the invention can be realized through following technical scheme:
A kind of environment-friendly type city bus gas circuit control convenience comprises pressure switch, high-voltage relay, DC/AC change-over circuit, air compressor, power supply, and described power supply is connected with the DC/AC change-over circuit; The contact of described DC/AC change-over circuit, high-voltage relay, air compressor, DC/AC change-over circuit are connected into the loop successively; One end of the coil of described high-voltage relay is connected with pressure switch, and other end ground connection is characterized in that; Described control setup also comprises normally open solenoid valve; Magnet coil one end of this normally open solenoid valve is connected with pressure switch, other end ground connection, and the valve body of described normally open solenoid valve is contained in the exit of air compressor;
When the air pressure in the storage tank dropped to setting value, pressure switch was closed, and the closing of contact of high-voltage relay drives air compressor work, and normally open solenoid valve cuts out simultaneously, and pressurized air gets into storage tank;
When storage tank pressure rises during to setting value, pressure switch is broken off, and the contact open of high-voltage relay quits work air compressor, and normally open solenoid valve is opened simultaneously.
The valve body of described normally open solenoid valve is installed in the exit of air compressor through T-pipe joint.
Compared with prior art, the present invention has can avoid the air compressor loaded starting, pollutes for when both having protected air compressor also to avoid the air compressor loaded starting car load power supply.

When storage tank air pressure is reduced to 0.4MPa, pressure switch 1 closure, high-voltage relay 2 adhesive air compressors 3 are started working, and normally open solenoid valve 4 cuts out simultaneously, and pressurized air gets into storage tank;
When the storage tank pressure rises arrives 0.8MPa; Pressure switch 1 is broken off, and high-voltage relay 2 breaks off air compressor 3 and quits work, and normally open solenoid valve 4 is opened simultaneously; Air compressor 3 mouth air pressure are reduced to 0MPa, so just get ready for air compressor 3 next working cycle starting under no loads.
When pressure was between 0.4MPa and 0.8MPa, pressure switch 1 was in hold mode.
The valve body of described normally open solenoid valve is installed in the exit of air compressor through T-pipe joint.
Claims (2)
