Description
Technical field
The present invention relates to a kind of water pump, a kind ofly make pump chamber water inlet and outlet end pressure constantly change the rotary-piston water pump that reaches suction and the purpose of pumping up water by rotary piston structure thereby particularly relate to.
Technical background
At present, centrifugal pump is because of simple in structure, and is easy for installation, low price and become the leading products of water pump.But people have ignored two fatal shortcomings of centrifugal pump.First shortcoming, efficient is low, and particularly under higher pressure, the efficient of most water pumps has been wasted a large amount of energy often less than 50%, and this increases its operating cost greatly.Some large-scale water lift engineerings particularly, the consumption of electricity charge every day can reach millions of units, and the waste of the energy will bring huge economic loss.Second shortcoming, pressure is little.Most of centrifugal lift of pump are only having twenty or thirty rice, and the centrifugal lift of pump that even has only has several meters, and this dwindles the usage range of centrifugal pump greatly, and a lot of operating conditions centrifugal pumps can't be competent at.
Summary of the invention
The objective of the invention is in order to overcome the shortcoming of prior art, provide that a kind of efficient is high, pressure is large, flow is large, the rotary-piston water pump of simple in structure and superior performance applied range.
For achieving the above object, the technical solution used in the present invention is: a kind of rotary-piston water pump, comprise hollow shell, housing both ends open and be respectively arranged with protecgulum and the bonnet of sealability, housing top is respectively arranged with water intake and water outlet, be provided with slider between water intake and water outlet, be provided with slewing gear in housing, slewing gear is separated water intake and water outlet together with slider.
In such scheme, described slewing gear comprises greater trochanter and a plurality of little cam, its medium and small cam is arranged on the greater trochanter periphery and can synchronously rotates with greater trochanter, little cam end portion is fixedly connected with small gear, small gear intermeshes with the change gear that is arranged on greater trochanter, change gear intermeshes with the fixed gear that is arranged on bonnet, when greater trochanter drives little cam and change gear rotation, under the effect of fixed gear, this moment, the sense of rotation of change gear was identical with greater trochanter, under the effect of change gear, rotation does not occur in little cam.
Further describe, little cam in such scheme is arranged in a plurality of grooves of offering on the greater trochanter outer wall, in the process of rotating, has at least the outer rim of a little cam and housing inner edge to fit, in the process of little cam through the slider position, little cam is placed in groove fully.Avoided little cam and slider mutually to collide.
Can find out from the technical characteristics of the invention described above, its advantage is: this rotary-piston water pump adopts the work of capacity contraction principle, is comprised of shell and slewing gear, and slewing gear and shell form continuous rotary volume-variable and amass the district, form continuous expansion and compression, realize suction and the function of pumping up water.The continuous pulsating movement free of this rotary-piston pump capacity, working principle is very simple, and is rational in infrastructure, possesses simultaneously a lot of performance advantages, and its outstanding performance advantage is embodied in:
1, efficient is high and stable, and this rotary-piston water pump is equivalent to a reciprocating piston pump with endless stroke, and its structural feature can make its efficient reach more than 95%, and efficient is little with lift variation fluctuation.Energy-saving effect is very remarkable, is that Centrifugal water pump is too far behind to catch up.
2, this rotary-piston water pump can be used as turbine pump, liquid with certain pressure intensity is during by this rotary mercury pump, can drive this rotary-piston water pump rotation, this moment this rotary-piston water pump output power, and it is when the turbine pump, efficient still can reach more than 95%, and other turbine pump most effective only 80%.Simultaneously, it also can be used as steam engine etc., absorbs the pressure energy that various fluids contain.This rotary-piston water pump that a plurality of sizes are constantly increased is in series, and will form decompressor.
3, pressure is large, because this rotary-piston water pump is capacity formula water pump, thus can produce higher pressure, more than its pressure energy reaches 5MPa.
4, flow is large, and this rotary-piston pumps design is reasonable, sucks splendidly, and the pump chamber section area is large, and compact structure, and small volume is so the flow of this rotary-piston water pump is much larger than the flow of comparable size Centrifugal water pump.
5, cost performance is high, due to its structure and principle simple, volume is little, flow is large, low cost of manufacture, the manufacture cost of this rotary-piston water pump is also lower than the Centrifugal water pump of equal flow.
6, have very strong self-absorption function, need not to add diversion, very easy to use.
7, flow is controlled and excursion is large, and the flow of this rotary-piston water pump and lift are irrelevant, and in the rated speed scope, flow is directly proportional to rotating speed, and the available adjustment rotating speed is regulated its flow, and its flow can be in zero variation arbitrarily in the peak rate of flow scope.
8, bidirectional reversible, the structure full symmetric of this rotation rotary-piston water pump is when changing sense of rotation, feed-water end and waterexit end reciprocity.
9, the power source selection scope is wide, because this rotary-piston water pump is very little to the requirement of rotating speed, can change in the rated speed scope from zero, so this rotary-piston water pump can connect with various power sources, electric power, internal-combustion engine, wind-force, waterpower, manpower etc.
10, using scope is wide, but this rotary-piston water pump has, and pressure is large, the changes in flow rate scope large, the power source selection scope is wide, the bidirectional reversible self-priming, can be used as turbine pump, and it can also be as air exhauster, the advantages such as air compressor, and this can be competent at multiple operating conditions.
11, operate steadily, a plurality of little cam of this rotary-piston water pump impose at any time trochiterian power all mutual balance, cancel out each other, so this rotary-piston water pump can smooth running as Centrifugal water pump, there is no larger vibration and noise.
According to the above, the combination property advantage of this rotary-piston water pump far away higher than Centrifugal water pump, is a great innovation and breakthrough in water pump field.
