Start and stop.
In some embodiments, after the order that controller obtains driver's closing hydraulic motor, pass through motor driver 7
Directly controlling motor 9 reduces power.
There are two types of work patterns for the road sweeper tool of the present embodiment, and wherein the first work pattern is the horse for driving water pump
Low-power mould up to high-power mode when work, when second of work pattern is for driving the motor of water pump to stop working
Formula.
The present embodiment is achieved in that the hydraulic horse for being opened and closed water pump with driving water pump being arranged in driver's cabin 4
Up to 12 operating member 5, operator is in the main control in control cabinet when closing hydraulic motor and water pump by operator
Device 1 detects signal, and makes 8 coil losing electricity of relay, and motor driver 7 detects 8 contact of relay and disconnects, then it is assumed that present
Work pattern is low-power mode, and motor driver 7 reduces by 9 revolving speed of motor, and the discharge capacity and power of hydraulic pump 11 also drop therewith
It is low, while master controller 1 makes 10 power loss of solenoid valve, closes the hydraulic motor 12 of driving water pump.
When the operating member 5 by being arranged in driver's cabin 4 opens water pump and drives the hydraulic motor of water pump, it is in control
Master controller 1 in case detects that signal makes 8 coil of relay be powered, and motor driver 7 detects 8 contact of high-pressure hydraulic pump relay
Closure, then it is assumed that present work pattern is high-power mode, and hydraulic electric motor driver 7 is by 9 turns of motor of hydraulic drive unit
Speed improves, and the discharge capacity and power of pump also increase accordingly, at the same master controller 1 make electromagnetic valve for water pump 10 it is electric, open driving water pump
Hydraulic motor 12.
The road sweeper of the present embodiment has following technical effect that
Electric road sweeper includes master controller 1, the motor 9 for driving hydraulic pump, motor driver 7, is used for start and stop water pump
Solenoid valve 10, the operating member 5 and the relay 8 that control for operator water pump and hydraulic motor 12 etc. constitute.Operator
It can be the work pattern of controllable electric road sweeper by control operating member 5, it is easy to learn, facilitate operation, simplifies electrical
The volume and spool road arrangement of system and hydraulic system, maintain easily.When being in low-power mode, the row of hydraulic power unit
Amount and power be in reduced levels, meet of short duration mechanism action, when being in high-power mode, the discharge capacity of hydraulic power unit and
Power is in higher level, while meeting of short duration mechanism action, it is ensured that the normal work of high-pressure hydraulic pump motor.Operation
Person only need to be simply by switch control work pattern, so that it may complete the required power unit of cleaning work different rotating speeds and
The switching of operating mode utilizes the capacity usage ratio of vehicle and operating efficiency rationally, avoids energy loss and waste, from
And the calorific value of vehicle hydraulic system is reduced, increase operation course continuation mileage and the activity duration of vehicle.
In some embodiments, monitoring component can be the pressure sensor for detecting the output pressure of water pump.It is grasping
Make personnel to control after hydraulic motor 12 stops operating by operating member 5, the pressure reduction that pressure sensor detects, pressure passes
Force information back to controller, controller are reduced the power of motor 9 by sensor.
The foregoing is merely exemplary embodiment of the present invention, are not intended to limit the invention, all in spirit of the invention
Within principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
