Abstract
The invention discloses a kind of dryer system and its control method, including choke valve, unloading valve, filter, air cleaner, magnetic valve, check valve and drier, choke valve, unloading valve, filter, air cleaner, magnetic valve, check valve are corresponding to be connected with drier.The stopping and drier off-load of air pump are controlled according to gas receiver pressure, and such pneumatic control system can be more accurate.Will not be because of in order to ensure drier off-load, the situation that inflating pump delay is inflated occurs, and so as to save electric energy, and can control the time speed of drier off-load at any time and blowback, extend drier service life.
Description
Technical field：
The present invention relates to a kind of dryer system and its control method.
Background technology：
The brakes of car typically uses double-loop air brakes.Before starting, inflating pump is inflated to gas receiver,
When reaching the atmospheric pressure value of gas receiver setting, inflating pump enters line delay, it is ensured that drier can be with blowback with off-load, regenerating tank.
But the method needs inflating pump to enter line delay, waste electric energy (for pure electric coach).
The content of the invention：
The present invention is to provide a kind of dryer system and its controlling party to solve the above-mentioned problems of the prior art
Method.
The present invention adopts the following technical scheme that：A kind of dryer system, including choke valve, unloading valve, filter, air mistake
Filter, magnetic valve, check valve and drier, choke valve, unloading valve, filter, air cleaner, magnetic valve, check valve are corresponding
It is connected with drier.
The present invention also adopts the following technical scheme that：A kind of control method of dryer system, comprises the following steps：
The first step：When vehicle starts for the first time, vehicle control unit controls inflating pump acquiescence work 8 minutes, work as air pressure sensing
When device sensing gas receiver pressure reaches the 0.8Bar pressure of default, entire car controller is by controlling magnetic valve in drier
Long come makes 3 mouthful discharges of the gas unnecessary in inflating pump by drier, until inflating pump is stopped；
Second step：After vehicle starts for the first time, when the pressure of baroceptor sensing gas receiver is less than default
During 0.68Bar pressure, vehicle control unit controls inflate pump startup, start to inflate, when baroceptor senses gas receiver pressure
When reaching the 0.8Bar pressure of default, now inflating pump is stopped, and entire car controller is by controlling electromagnetism in drier
Valve opens 10s, makes its off-load 10s, so as to which regenerating tank carries out blowback, after 10s, closed electromagnetic valve in drier, waits next
Secondary instruction arrives.
The present invention has the advantages that：The stopping and drier off-load of air pump are controlled according to gas receiver pressure
System, such pneumatic control system can be more accurate.Will not be because of the feelings that in order to ensure drier off-load, inflating pump delay is inflated
Condition occurs, and so as to save electric energy, and can control the time speed of drier off-load at any time and blowback, and extending drier makes
Use the life-span.
Brief description of the drawings：
Fig. 1 is structure chart of the present invention.
Embodiment：
The present invention is further illustrated below in conjunction with the accompanying drawings.
As shown in figure 1, the present invention discloses a kind of dryer system, including choke valve 1, unloading valve 2, filter 3, air mistake
Filter 4, magnetic valve 5, check valve 6 and drier 7, choke valve 1, unloading valve 2, filter 3, air cleaner 4, magnetic valve 5, list
It is connected to valve 6 is corresponding with drier 7.
The A mouths of drier 7 are air inlets, represent the gas come in from inflating pump.B mouths represent the gas outlet of drier, this
The gas of gas outlet leads to gas receiver.C mouths also represent the gas outlet of drier, and the gas of this gas outlet leads to regenerating tank.D mouth generations
The exhaust outlet of table drier, the gas in regenerating tank in the gas and inflating pump of blowback are discharged from this mouth.
Choke valve 1 is used for controlling the flow of air inlet and the blowback of regenerating tank, postpones the blowback time, makes the drier of drier
Effective regeneration.
Unloading valve 2 is used for controlling the exhaust of drier, when controlling unloading valve 2 to open, gas and regeneration in inflating pump
Gas passes through 3 mouthfuls of discharges in tank.There is overload protection function in unloading valve 2, when 1 mouthful of gas flow of drier is excessive, off-load
Valve 2 is opened, and gas is discharged from 3 mouthfuls.
Filter 3 is used for filtering off dust and tiny solid impurity in air, but the moisture that can not be crossed in air filtering and
Oil droplet, equivalent to the function of coarse filtration.
Air cleaner 4 is used for filtering middle excessive moisture and oil droplet in the compressed air come out from source of the gas, equivalent to thin
Consider.
Magnetic valve 5 is a kind of normally closed type 2/2-way magnetic valve, for controlling unloading valve to open.When the pressure of gas receiver reaches
During to setting, vehicle control unit controls magnetic valve 5 is opened, and then controls unloading valve 2 to open.
Check valve 6 is used for preventing the gas in gas receiver from being discharged from drier exhaust outlet.
The control method of dryer system of the present invention, including：
The first step：When vehicle starts for the first time, vehicle control unit controls inflating pump acquiescence work 8 minutes, work as air pressure sensing
When device sensing gas receiver pressure reaches the 0.8Bar pressure of default, entire car controller is by controlling magnetic valve in drier
Long come makes 3 mouthful discharges of the gas unnecessary in inflating pump by drier, until inflating pump is stopped；
Second step：After vehicle starts for the first time, when the pressure of baroceptor sensing gas receiver is less than default
During 0.68Bar pressure, vehicle control unit controls inflate pump startup, start to inflate, when baroceptor senses gas receiver pressure
When reaching the 0.8Bar pressure of default, now inflating pump is stopped, and entire car controller is by controlling electromagnetism in drier
Valve opens 10s, makes its off-load 10s, so as to which regenerating tank carries out blowback.After 10s, closed electromagnetic valve in drier, wait next
Secondary instruction arrives.
Described above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, some improvement can also be made under the premise without departing from the principles of the invention, and these improvement also should be regarded as the present invention's
Protection domain.
