Description
Technical field
The utility model relates to a kind of hydraulic pump, particularly a kind of hydraulic centrifugal water pump of continuous speed adjustment.
Background technique
Centrifugal water pump in daily life, and is very common, for example tap water supply system.Generally be by the rotation of motoring water pump, the water pump rotation is delivered to high-pressure water tank with water.Up-to-date hydrotechny adopts variable-frequency motor to drive water pump, by the change frequency of supply, thus the rotational speed of change motor and water pump, in order to adapt to the demand of different water outputs.Yet existing this hydraulic pump can not adapt to field work for generally being to be fixed on the operational site.
The model utility content
The purpose of this utility model is for overcoming the defective that prior art exists, drive needs with the water pump that adapts to mobile device or field work, and we have designed the hydraulic centrifugal water pump, just utilize the fluid motor-driven pump working.
For achieving the above object, the utility model is taked following technological scheme:
A kind of hydraulic centrifugal water pump of continuous speed adjustment, it is characterized in that, comprise oil hydraulic motor belt pulley, centrifugal water pump belt pulley, centrifugal water pump, Idle wheel, support, oil hydraulic motor and synchronous band, centrifugal water pump and oil hydraulic motor are installed on the support, the oil hydraulic motor belt pulley is installed on the oil hydraulic motor, the centrifugal water pump belt pulley is installed on the centrifugal water pump, Idle wheel is installed on the support, between oil hydraulic motor belt pulley and centrifugal water pump belt pulley, the oil hydraulic motor belt pulley is in transmission connection through Idle wheel and centrifugal water pump belt pulley by synchronous band.
The working principle of the hydraulic centrifugal water pump of the utility model continuous speed adjustment is:
The input of hydraulic system power by power take-off, drives the variable hydraulic planger pump by motor car engine.Hydraulic system can change the flow of hydraulic system according to the oil hydraulic motor tach signal, the hydraulic fluid flow rate that oil hydraulic motor obtains changes, and the oil hydraulic motor rotating speed changes thereupon, by synchronous band transmission, the rotating speed of centrifugal water pump changes thereupon, and the water output of centrifugal water pump output changes thereupon.
By detecting hydraulic centrifugal exit of pump working pressure or flow, when load flow diminishes, at this moment the centrifugal water pump outlet pressure can increase thereupon, centrifugal water pump outlet pressure or flow transducer are with the signal of detected outlet pressure or flow increase, pass to hydraulic system, hydraulic system reduces to export the hydraulic pressure oil mass, and the oil hydraulic motor rotating speed reduces, the centrifugal water pump rotating speed reduces, and the water output of output reduces thereupon.By changing the rotating speed of oil hydraulic motor, reached the purpose that adapts to load flow.
Same reason, when the centrifugal water pump load flow increased, outlet pressure can reduce, and the hydraulic pressure of hydraulic system output at this moment oil mass increases, and the rotating speed of oil hydraulic motor and centrifugal water pump increases, and the centrifugal water pump output flow increases thereupon.
Because whole process hydraulic system and centrifugal water pump system all do not have overflow to produce, so be energy-conservation system.Centrifugal water pump is used for mobile device, reduces weight and floor space.
Because the working pressure of centrifugal water pump can reach about 0.5MPa, so the pressure of supply water of the hydraulic centrifugal water pump of this continuous speed adjustment can reach about 0.5MPa.
By structural drawing as can be seen, oil hydraulic motor is given centrifugal water pump by synchronous band, two belt pulleys with transmission of power, during the water pump rotation, can realize from water tank suction and the pressurization of feeding water.
The effect of the hydraulic centrifugal water pump of the utility model continuous speed adjustment:
Realize open-air water supply or mobile water supply.Do not need high-pressure water tank, can realize that variation according to the load flow size provides the water source of different flow.Because to be speed governing simple and regulation range is very big for the characteristics of Hydraulic Adjustable Speed, much larger than the speed adjustable range of variable-frequency motor, regulate on a large scale so can realize water output.
