Description
Technical field
The present invention relates to Retarder technical field, in particular to the control of a kind of automobile-used Retarder of underground work
System.
Background technique
It does not retrieve and uses the prior art of Retarder in underground vehicle.Underground vehicle uses Retarder,
In view of its special use environment, vehicle has higher requirement of explosion proof, it is therefore desirable to reduce the use of electric component.
Summary of the invention
Technical problem solved by the invention be to provide it is a kind of set several groups for Manual pressure regulating valve, different groups set
Different pressure values is set, keeps operation easier, the air inlet of retarder, the exhaust automobile-used fluid power of the faster underground work of response speed are slow
The control system of fast device.Have a higher requirement of explosion proof it is a further object of the present invention to provide a kind of adaptation underground vehicle, reduce or
The control system of the automobile-used Retarder of the underground work for avoiding electric component from using.Another object of the present invention is to provide one kind
When there is overtemperature prompt, driver should turn down output pressure immediately, avoid the underground of the damage of retarder or vehicle part
The control system of the automobile-used Retarder of operation.
The control system of the technical solution of the invention is as follows the automobile-used Retarder of underground work, including fluid power are slow
Fast device, is characterized in that, the Retarder, which is respectively connected to, to be driven indoor Manual pressure regulating valve and show
Show that module, compressed air divide two-way, accesses Manual pressure regulating valve all the way, another way access setting is in Retarder and manually
Relay valve between pressure-regulating valve in pipeline, the relay valve are equipped with exhaust pipe, and the relay valve air inlet connects compressed air,
The pressure modulating opening takes over dynamic pressure force regulating valve, and the servo valve air gate connects retarder, and the exhaust outlet leads to atmosphere；The outlet
Mouthful pressure according to the change in pressure of pressure modulating opening, when the pressure of pressure modulating opening is 0, compressed air in retarder from after
The exhaust outlet discharge of dynamic valve；The gas of the Manual pressure regulating valve export-restriction air pressure is to the Retarder；It is described aobvious
Show module by+24VDC power supply power supply and be grounded, the Retarder is respectively equipped with cooling water inlet pipe interface and cooling water goes out
Waterpipe jointing.
As preferred: the Retarder accesses the display module through water temperature sensor and oil temperature sensor respectively.
As preferred: the Manual pressure regulating valve is arranged in parallel several groups, and every group of output pressure is 0 or setting pressure
The setting pressure of power, difference group is different；Several groups Manual pressure regulating valve is respectively connected to compressed air and export-restriction air pressure
After gas is respectively connected to the relay valve, while accessing the Retarder.
Compared with prior art, beneficial effects of the present invention:
(1) Manual pressure regulating valve and display module are all mounted in driver's cabin, and driver is facilitated to operate and observe.
(2) Manual pressure regulating valve is limited equipped with highest output pressure, damage caused by preventing Retarder from overloading, In
Highest air pressure is hereinafter, stepless manually or have grade to adjust air pressure, to realize control to Retarder torque.
(3) driver turns down output pressure immediately when there is overtemperature prompt, avoids the damage of retarder or vehicle part
It is bad, customer requirement is answered, display module can do overtemperature prompt with displays temperature numerical value or only, can prompt simultaneously with overtemperature buzzing.
(4) customer requirement answered, and display module can increase that pressure is shown or superpressure (prevents from overloading) prompt facility, slow
Pressure sensor is installed on device, or pressure sensor or pressure gauge are installed in regulating valve delivery outlet.
(5) the quantity of Manual pressure regulating valve is increased, but operation is easier, the air inlet of retarder is vented response speed more
Fastly.
Detailed description of the invention
Fig. 1 is the control system block diagram of the automobile-used Retarder of underground work of the present invention.
Specific embodiment
The present invention is further detailed in conjunction with the accompanying drawings below:
Refering to Figure 1, the control system of the automobile-used Retarder of underground work, including Retarder,
It being characterized in that, the Retarder, which is respectively connected to, drives indoor Manual pressure regulating valve and display module,
Compressed air divides two-way, accesses Manual pressure regulating valve all the way, and another way access is arranged in Retarder and Manual pressure tune
The relay valve between valve in pipeline is saved, the relay valve is equipped with exhaust pipe, and the relay valve air inlet connects compressed air, the tune
Mouth is pressed to take over dynamic pressure force regulating valve, the servo valve air gate connects retarder, and the exhaust outlet leads to atmosphere；The pressure of the gas outlet
Power is according to the change in pressure of pressure modulating opening, and when the pressure of pressure modulating opening is 0, compressed air in retarder is from relay valve
Exhaust outlet discharge；The gas of the Manual pressure regulating valve export-restriction air pressure is to the Retarder；The display module
It by+24VDC power supply power supply and is grounded, the Retarder is respectively equipped with cooling water inlet pipe interface and cooling water outlet pipe connects
Mouthful.
In the present embodiment, the Manual pressure regulating valve is arranged in parallel several groups, and every group of output pressure is 0 or setting pressure
