Technical field
This utility model relates to a kind of watering vehicle intelligent dosing pump water system, be widely used in the dosing pump of the saline in saline distribution vehicle, road cleaning vehicle, environmental sanitation greening vehicle, alkalescent water and pure water to.
Background technology
There are an important functional requirement, i.e. the spread uniformity in sprinkling truck. No matter sometimes requiring that speed is high and low, the watering amount on every square metre of road surface wants homogeneous constant. Require the output of water pump, with the travel speed linear proportional relation of vehicle, speed is more high, and output is more big.
The pumping system on current domestic sprinkling truck, can only accomplish the output of water pump and the rotating speed linear proportional relation of electromotor, it does not have accomplish and speed linear proportional relation.
The operation principle of water system is shown in that accompanying drawing 1, electromotor 1 drive oil pump 2 to motor 3 fuel feeding, and motor 3 drives water pump 4 water-pumping/draining by shaft coupling.
Having this visible, the rotating speed linear proportional relation of pump rotary speed and electromotor, engine speed is more high, and pump rotary speed is more high, and water-pumping/draining flow is more big.
And vehicle to run speed is not only relevant to engine speed, also relevant to change speed gear box high low gear. Vehicle is when actual job, and driver according to road conditions, can adopt different gears to travel.
Same engine speed, because gear difference speed difference is very big, the watering amount difference causing unit are road surface is bigger, it is impossible to realize uniformly dispensing.
Summary of the invention
The technical problems to be solved in the utility model is for problem above, it is provided that one can improve watering vehicle
Watering efficiency, improve the utilization rate of spread liquid, pump capacity can be dynamically controlled, it is ensured that every square metre of road surface watering amount is definite value, and alleviates the operation easier of operator and the watering vehicle intelligent dosing pump water system of labor intensity according to the speed that vehicle travels.
In order to solve the problems referred to above, this utility model is by the following technical solutions: a kind of watering vehicle intelligent dosing pump water system, including metering pump device, metering pump device includes the water pump and the hydraulic motor that are fixed together, and the output shaft of water pump is connected by shaft coupling transmission with the power shaft of hydraulic motor.
The following is further improvement of the utility model:
Described intelligence dosing pump water system also includes controller, and controller is for controlling the rotating speed of metering pump device.
Improve further:
Being connected to electro-hydraulic servo choke valve on described hydraulic motor, electro-hydraulic servo choke valve is for controlling the oil inlet quantity of hydraulic motor.
Improve further:
Being also associated with motor rotary speed induction apparatus on described hydraulic motor, motor rotary speed induction apparatus is for measuring the rotating speed of hydraulic motor.
Improve further:
Described controller electrically connects with motor rotary speed induction apparatus and electro-hydraulic servo choke valve.
Improve further:
Oil seal plate it is provided with between water pump and hydraulic motor.
After this utility model adopts technique scheme to have following technical effect that water pump system of the present utility model loaded onto by the watering vehicles such as saline distribution vehicle, road cleaning vehicle, environmental sanitation greening vehicle, operator can according to actual condition needs, determine the watering amount that every square meter road surface needs, after input control system, control system can dynamically control pump capacity according to speed, guaranteeing the definite value that every square metre of road surface watering amount is input, driver can arbitrarily regulate and control speed; The watering efficiency of watering vehicle can improve 30%, and the utilization rate of spread liquid improves 50%, and the operation easier of operator and intensity also can be substantially reduced about half, and social benefit is very good.
It is described further originally novel below in conjunction with drawings and Examples.
