Abstract
The utility model is related to a kind of vacuum sweeper blower fan control system of invariable pressure, with the working condition of real-time control blower fan, make air inlet pressure all the time in steady state, to improve the operating efficiency of blower fan, and solve pavement garbage amount it is excessive when, the not good shortcoming of pick-up performance.It includes air inlet, B/P EGR Back Pressure Transducer EGR, Engine ECU, centrifugal blower, assistant engine, driving belt, it is characterised in that：B/P EGR Back Pressure Transducer EGR is arranged at air inlet, B/P EGR Back Pressure Transducer EGR detection blower fan air inlet pressure, and pressure signal is converted into current signal sends to Engine ECU, air inlet is arranged on centrifugal blower, and Engine ECU is arranged on assistant engine, by closed-loop control, control assistant engine rotating speed, assistant engine is connected by driving belt with centrifugal blower, by changing assistant engine rotating speed, control centrifugal blower rotating speed, and then control fan outlet pressure.
Description
Technical field：
The utility model belongs to special purpose vehicle technical field, more particularly to a kind of vacuum sweeper blower fan control system of invariable pressure.
Background technology：
Vacuum sweeper is the environmental sanitation engineering goods of new generation being received by the market developed in recent years.Vacuum sweeper is using blower fan
Powerful suction and soil pick-up disk all reclaim the rubbish on road surface and dust, and the cleaning, clearly of rubbish can disposably be completed in operation
The recovery of reason and rubbish, operation effectiveness is better than traditional sweeping machine and sweeper.And blower fan as vacuum sweeper core component it
One, performance and the working condition quality of blower fan are directly connected to the clean-up performance on road surface, and then have influence on the usability of vehicle
Energy.But traditional vacuum sweeper is in use, when pavement garbage amount is excessive, pressure drop at air inlet can be caused
It is low, it is impossible to reclaim pavement garbage completely, so as to cause pick-up performance not good, have a strong impact on the performance of vehicle.For this we
A kind of vacuum sweeper blower fan control system of invariable pressure is devised, with the working condition of real-time control blower fan, air inlet pressure is begun
Eventually be in steady state, to improve the operating efficiency of blower fan, and solve pavement garbage amount it is excessive when, pick-up performance it is not good lack
Point.
The content of the invention
The purpose of this utility model is, to overcome disadvantages mentioned above, and to provide a kind of vacuum sweeper blower fan control system of invariable pressure.
The technical scheme that the utility model is used is implemented：A kind of vacuum sweeper blower fan control system of invariable pressure, bag
Include air inlet, B/P EGR Back Pressure Transducer EGR, Engine ECU, centrifugal blower, assistant engine, driving belt, it is characterised in that：Negative pressure
Sensor is arranged at air inlet, B/P EGR Back Pressure Transducer EGR detection blower fan air inlet pressure, and pressure signal is converted into electricity
Stream signal is sent to Engine ECU, and air inlet is arranged on centrifugal blower, and Engine ECU is arranged on assistant engine, is led to
Closed-loop control is crossed, controls assistant engine rotating speed, assistant engine to be connected with centrifugal blower by driving belt, start by changing pair
Machine rotating speed, controls centrifugal blower rotating speed, and then control fan outlet pressure.
The utility model has superior performance, safe and reliable, the characteristics of easy to use.
Brief description of the drawings：
Fig. 1 is schematic diagram of the present utility model；
Fig. 2 is front view of the present utility model；
Fig. 3 is top view of the present utility model；
In figure：1. air inlet, 2. B/P EGR Back Pressure Transducer EGR, 3. Engine ECU, 4. assistant engine, 5. centrifugal blower, 6.
Driving belt.
Specific embodiment：
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of vacuum sweeper blower fan control system of invariable pressure, including air inlet 1, negative pressure is sensed
Device 2, Engine ECU 3, assistant engine 4, centrifugal blower 5, driving belt 6, it is characterised in that：B/P EGR Back Pressure Transducer EGR 2 is arranged on blower fan
At air inlet 1, pressure at the detection blower fan air inlet 1 of B/P EGR Back Pressure Transducer EGR 2, and pressure signal is converted into current signal sends to hair
Motivation ECU3, air inlet 1 is arranged on centrifugal blower 5, and Engine ECU 3 is arranged on assistant engine 4, by closed loop control
System, controls the rotating speed of assistant engine 4, and assistant engine 4 is connected by driving belt 6 with centrifugal blower 5, by changing assistant engine
4 rotating speeds, control the rotating speed of centrifugal blower 5, and then control the pressure at fan outlet 1.
Embodiment：When vacuum sweeper in the course of the work, run into pavement garbage amount it is excessive when, centrifugal fan air outlet 1 is pressed
Power step-down, when blower fan suction declines, the pressure signal that B/P EGR Back Pressure Transducer EGR 2 will can be detected is sent to after being converted into current signal
Motivation ECU3, Engine ECU 3 controls the rotating speed of assistant engine 4 by closed-loop control system, pressure value at fan outlet 1 is begun
Keep constant eventually, so as to ensure that the suction of blower fan, to reach good refuse collection effect.
