Description
Technical field
The utility model relates to the control device of the electronic bus in city, the control device of particularly automatically controlled compressor and the synchronous off-load of air dryer.
Background technology
Along with the continuous expansion of the electronic public transport in city, environmental protection and the energy-conservation theme that becomes.There are a lot of problems in traditional electronic bus aspect the battery service efficiency, cause electric energy to use and insufficiently can not reach environmental protection and requirements of saving energy.How to improve the electrokinetic cell service efficiency, saves energy has become the trend that automobile industry develops.
Summary of the invention
The purpose of this utility model provides the control device of a kind of automatically controlled compressor and the synchronous off-load of air dryer, improves the battery service efficiency, saves energy.
The technical solution of the utility model is: the control device that relates to automatically controlled compressor and the synchronous off-load of air dryer, it comprises magnetic valve, gas receiver, pressure sensor, check valve, moisture bottle, drier and for the automatically controlled compressor of off-load, it is characterized in that: adopt " four-hole " drier, " 21 mouthfuls " of drier are connected with the moisture bottle by check valve, " 22 mouthfuls " of drier are connected with gas bomb, " 4 mouthfuls " of drier are connected with magnetic valve, " 1 mouthful " of drier be connected for the automatically controlled compressor of off-load; " 22 mouthfuls " of drier are equipped with pressure sensor; Magnetic valve is connected with gas bomb.
Described drier select tape control drier can be joined for the automatically controlled compressor of off-load and be used.
Described magnetic valve is selected the two-bit triplet type, and model is Da21M-60c.
It is XMP-D12BZ242 that described pressure sensor is selected model, and the pressure sensor setting is 0.85MP by low pressure toward high disconnection, is 0.65MP by height to low cut-in pressure.
Characteristics of the present utility model are: improve the electrokinetic cell service efficiency, save electric energy, the car load air compressor machine adopts service intermittent, reaches environmental protection and purpose of energy saving.When being higher than the 0.85Mp air compressor machine, air-channel system pressure quits work the drier blowdown.Air compressor machine can start once more when treating that gas circuit pressure is lower than 0.65Mp.

Specific embodiment
Embodiment 1: as shown in Figure 1 and Figure 2, the control device of automatically controlled compressor and the synchronous off-load of air dryer, it comprises magnetic valve 1, gas receiver 2, pressure sensor 7, check valve 4, moisture bottle 5, drier 3 and for the automatically controlled compressor 6 of off-load, it is characterized in that: adopt " four-hole " drier 3, " 21 mouthfuls " of drier 3 are connected with moisture bottle 5 by check valve 1, " 22 mouthfuls " of drier 3 are connected with gas bomb 2, " 4 mouthfuls " of drier 3 are connected with magnetic valve, " 1 mouthful " of drier 3 be connected for the automatically controlled compressor 6 of off-load; " 22 mouthfuls " of drier 3 are equipped with pressure sensor 7; Magnetic valve 1 is connected with gas bomb 2.
Embodiment 2: as shown in Figure 1 and Figure 2, as different from Example 1, select band control drier 3 for use, can join for the automatically controlled compressor 6 of off-load and use, as shown in Figure 3, during the air compressor machine off-load of general engine band, need provide pressure signal by drier 3, be the control mouth " 4 mouthfuls " of drier 3, " 4 mouthfuls " are output at this moment.
As shown in Figure 4, the selection of pressure sensor 7 switches is the most important links of control, and through the type selecting contrast, having chosen sensor is XMP-D12BZ242, and pressure is 0.85MP by the low pressure that disconnects toward height, is 0.65MP by height to low cut-in pressure.
The control device of this automatically controlled compressor and the synchronous off-load of air dryer, utilize the regenerating tank of former car air-channel system to do source of the gas, the Compressed Gas of regenerating tank sent into the four-hole of drier through solenoid control, when pressure from the low process that raises gradually, when pressure is not raised to 0.85MP, sensing switch is in the close position all the time, and sensor disconnected when pressure reached 0.85Mp, the air compressor machine outage, quit work, solenoid relay valve work simultaneously, magnetic valve powers on, 4 mouthfuls of inflations of drier.
