Description
Technical field
The present invention relates to the special-purpose vehicle technical fields of automobile industry, further relate to the self-priming pump technical field of industrial centrifugal pump.
Background technique
Since the ponding of heavy rain or other reasons can usually be given, production, life is made troubles or disaster, accumulates there is burst
When water or flood, due to the pumping equipment that spot is usually not fixed, it is therefore desirable to which mobile facility carries out Quick drainage, speedily carries out rescue work
Operation.
The existing emergency in home and abroad water drainage vehicle and movable pump station are vehicular or towed at present, and vehicle or chassis are only
As the mobile vehicle of the drainage equipment such as water pump, power needed for usual pump working is supplied by independent generator set device.
Vehicular water drainage pump truck is the chassis that the facilities such as generating set or diesel engine unit and the water pump of driving are fixed on to vehicle
On, surrounding and top closed, power is provided by vehicle-based generator set or diesel engine unit, and high equipment cost, diesel engine noise is big,
It is complicated for operation.
Towed water drainage pump truck is also referred to as pulling type water drainage vehicle, is that the dedicated units such as generating set, water pump are fixed on trailer
On, surrounding and top are closed.Water drainage vehicle cannot walk alone, other traction devices is needed to pull or transport.Its feature is
It cannot walk alone, other features are identical as vehicular water drainage pump truck
Applicant in this case once developed a kind of self-driving type pump truck, had applied for utility model patent, and title is a kind of " self-powered
The strong self-priming flood fighting water drainage vehicle of formula ", Patent No.: ZL201420515163.9, its main feature is that: the power of pump is derived from car engine
Machine, the power of engine access power takeoff by gearbox, transmission shaft, and power takeoff has an input shaft and two output shafts,
In an output shaft normally connect rear axle and drive chassis normally travel, another output axis connection and transfer tube have on power takeoff
Arrangement of clutch.When running car, the output shaft for connecting pump is detached from；Conversely, connecting rear axle when the output shaft work of connection pump
Output shaft is detached from.As shown in figure 3,91 power of engine will be conveyed to rear power takeoff by gearbox 92, power takeoff driving shaft 93
94, an output shaft of rear power takeoff 94 drives transmission shaft 95 to connect rear axle differential 96 by vehicle, and another output shaft passes through
Pump driving transmission shaft 97 connect self priming pump 98, above-mentioned power takeoff be arranged in engine 91, gearbox 92, power takeoff driving shaft 93 it
Afterwards, referred to as rear power takeoff 94.It is this by way of 94 power taking of rear power takeoff, not only influence efficiency, also add transmission shaft
Quantity needs three transmission shafts to realize the driving of pump with vehicle altogether, and needs to change automobile chassis first wife's transmission shaft.
The mechanics feature of water pump requires its input driving power to have substantially invariable revolving speed, and at this moment its operation is just put down
Surely, under the premise of guaranteeing metered flow, rated head, guarantee that the efficiency of pump maximizes.Under normal circumstances, the rated speed of pump with
The corresponding electricity of asynchronous machine, revolving speed usually respectively correspond the asynchronous machines such as 2 grades, 4 grades, 6 grades, 8 grades, correspond, water pump
Rated speed is typically designed in 2900r/min, 1480r/min, 980r/min, 740r/min or so, depending on practical turn of asynchronous machine
Depending on speed.It, be using the outlet valve opening for adjusting pump, to realize adjustment lift, stream when needing to adjust flow, the lift of water pump
Amount, does not change the revolving speed of pump generally.As shown in Figure 1, water pump is when its rated speed is Nb, lift, flow, efficiency are best
Match point.
Since automobile needs to accelerate at any time in road surface normally travel, This vehicle stops frequently, it is therefore desirable to which the travel speed of automobile can
It is arbitrarily adjusted by 0km/h to 100km/h or so, in 0~6000r/min, gearbox low gear passes the revolving speed of such automobile engine
It is dynamic that than generally 6 or so, top gear transmission ratio is generally 0.6~0.8, by gearbox adjust the speed the revolving speed 0 of inter-axle shaft~
7000r/min or so.The revolving speed of transmission shaft is adjusted at random by driver's throttle and gear to the travel speed of automobile in other words
, it is difficult constant speed, it can not constant-speed traveling.
The traveling road conditions of automobile feature itself and complexity determine, it is necessary to can only change by adjusting throttle and gearbox shifting
The output torque for becoming transmission shaft, adjusts the travel speed of vehicle, guarantees that vehicle transmission shaft in low speed obtains more large torque, and when high speed is obtained
Must be bigger, to adapt to the running environment needs of moment change, especially quick start, the brake of quick reduction of speed, as shown in Figure 2.Vapour
The corresponding revolving speed of maximum torque point is Nf on car engine performance curve.
It can be seen that under prior art conditions, to realize mobility demand of the vehicle-mounted water pump when meeting an urgent need water drainage, use vapour
Car engine is come when driving water pump, if vehicle-mounted to drive by control throttle and gearbox gear with conventional car engine
Pump, engine difficult to realize is matched with the revolving speed of pump, torque and transmission efficiency maximizes.
