When change, can not adjust automatically imbibition revolution speed, be susceptible to suction pumps and vibrate excessive or emptying phenomenon, adaptability is poor；We
The foam liquid supply vehicle of company's design configures a suction pumps, can be with bilateral imbibition, and imbibition pump condition can be with the change of imbibition flow
Change adjust automatically matching, to ensure that suction pumps can be operated steadily under different imbibition operating modes
Invention content
The purpose of this utility model is to provide a kind of adaptive absorption foam liquid control system of single pump, can solve existing
Foam liquid supply vehicle in technology is of high cost, can not adjust automatically imbibition revolution speed, the shortcomings that bad adaptability.
The utility model uses following technical scheme：
A kind of single pump is adaptive to draw foam liquid control system, including foam solution suction pumps, and the foam solution suction pumps
Liquid sucting port the foam solutions of several foam solution liquid storing barrels is drawn by the connection of several electrically-controlled valves, the foam solution of absorption passes through quantitative liquid
The foam suction pumps of pressure motor driving are transported on liquid supply vehicle in flow container, the hydraulic pressure oil inlet and outlet connection of the constant displacement hydraulic motor
Motor control valve group, and the oil inlet of motor control valve group is connected to Variable plunger pump.
Variable plunger pump is electric proportional control Variable plunger pump, including volume adjustable hydraulic pump, electric proportional valve, variable piston and shuttle
The output end of valve, the signal output end link variable plunger of the shuttle valve, variable piston connects electric proportional valve.
The motor control valve group includes overflow valve, hydraulic directional valve, counterbalance valve, solenoid directional control valve.
The solenoid directional control valve is two four-way electromagnetic reversing valves, and hydraulic directional valve is two-position four-way hydraulic directional valve.
The utility model has the advantages that：The application of the foam liquid supply vehicle of uninterrupted feed flow, it is sustainable at large-sized fire scene
Foam solution constantly is provided for extinguishing vehicle, can be supplied from liquid supply vehicle either side according to scene of a fire situation foam bucket.
Description of the drawings
Attached drawing described herein is used for providing further understanding of the present application, constitutes part of this application, this Shen
Illustrative embodiments and their description please do not constitute the improper restriction to the application for explaining the application.In the accompanying drawings：
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
Presently filed embodiment is described in detail below in conjunction with accompanying drawings and embodiments, thereby how the application is applied
Technological means solves technical problem and reaches the realization process of technical effect to fully understand and implement.
As shown in Figure 1, a kind of single pump is adaptive to draw foam liquid control system, including foam solution suction pumps 4, and the bubble
The liquid sucting port of foam liquid suction pumps 4 is connected to the foam solution for drawing several foam solution liquid storing barrels, the bubble of absorption by several electrically-controlled valves 5
The foam suction pumps that foam liquid is driven by constant displacement hydraulic motor are transported on liquid supply vehicle in flow container, the constant displacement hydraulic motor 3
Hydraulic pressure oil inlet and outlet connects motor control valve group 2, and the oil inlet link variable plunger pump 1 of motor control valve group 2.
The Variable plunger pump 1 be electric proportional control Variable plunger pump, including volume adjustable hydraulic pump 1.1, electric proportional valve 1.2,
Variable piston 1.3 and shuttle valve 1.4, the signal output end link variable plunger 1.3 of the shuttle valve 1.4, the output of variable piston 1.3
End connection electric proportional valve 1.2, and electric proportional valve 1.2 is two-bit triplet electric proportional valve.
The motor control valve group includes overflow valve 2.1, hydraulic directional valve 2.2, counterbalance valve 2.3, solenoid directional control valve 2.4,
The solenoid directional control valve 2.4 is two four-way electromagnetic reversing valves, and hydraulic directional valve 2.2 is two-position four-way hydraulic directional valve.
The utility model list pump is adaptive to draw foam liquid control system, can be foam liquid supply vehicle using configuration suction pumps and
Solution feed pump is embodied as the scene of a fire and uninterruptedly conveys foam solution, and suction pumps are driven using side power takeoff, and solution feed pump uses off-axis power takeoff
Driving, suction pumps are interrupted when drawing barreled foam solution due to will produce, and to ensure uninterrupted feed flow, select the specified stream of suction pumps
Amount can draw barreled foam by the way that the control of valve in pipeline can be achieved more than the metered flow of solution feed pump at left and right sides of vehicle
Liquid；Foam liquid supply vehicle has multiple liquid sucting ports, and the variation of imbibition flow is will produce when drawing barreled foam, is controlled automatically by hydraulic pressure
System processed can be such that imbibition pump condition is matched with the variation adjust automatically of imbibition flow, to ensure suction pumps under different imbibition operating modes
Can steadily operate, it is of high cost to solve foam liquid supply vehicle in the prior art, can not adjust automatically imbibition revolution speed, adaptability
The disadvantage of difference.
Several preferred embodiments of the present invention have shown and described in above description, but as previously described, it should be understood that this
Utility model is not limited to form disclosed herein, is not to be taken as excluding other embodiments, and can be used for various
