The specific embodiment
Below, further specify flow counter of the present invention and pump integral apparatus in conjunction with the accompanying drawings.
Figure 1 shows that the composition frame diagram of flow counter of the present invention and pump integral apparatus, the inflow entrance 2 of flow counter and pump integral apparatus 1 is connected by the storage tanker that does not mark among pipe arrangement 3 and the figure.Simultaneously, inflow entrance 2 is connected with pump 6 by inlet side filter 4 and check valve 5.
Have, the outlet of pump 6 is connected with shunt valve 13 with sucking hole again, and shunt valve 13 is provided with bypass disc 14.Also have, the bunker oil that contains air that flows out from air eliminator 7 passes through pipeline 15 person who lives in exile's float bowls 16, and the pipeline 17 that bunker oil passes through returns a side of inflow pump, and air is put into atmosphere by floating on valve 18.
Following Fig. 2 is to Figure 6 shows that flow counter of the present invention and pump-integrated structure explanation.
According to shown in Figure 2, in the casing 19 of flow counter and pump integral apparatus 1, formed inflow entrance 2 by do not mark in pipe arrangement 3 connection diagrams and storage tanker.Simultaneously, inflow entrance 2 is connected with the sucking hole of pump 6 by inlet side filter 4 and check valve 5.And as requested, check valve 5 and the reverse configuration of sucking hole filter are also passable.
Sucking hole filter 4 is removed the grit in the fuel oil, and check valve 5 can prevent that the fuel oil counter-flow from going in the casing 19, causes air displacement.Also have, the inhalation power of pump 6 is stronger, can reduce the fault of gear type pump.
According to shown in Figure 3, the outlet 6a of pump 6 is connected with air eliminator 7, and the filter 8 of the pipeline of air eliminator 7 by outlet side returns with flow counter 9 and be connected.
Like this, pump 6 and flow counter 9 form connecting line in casing 19, because of pipeline returns, suppressed the interference of higher cycle pressure vibration, the rigidity height of pipeline, and the little noise of area lowers simultaneously, and the sprung back is few, can reduce the vibration of flow counter.Have, because of pipeline shortens, capacity also reduces again, and because of cavitation build-up of pressure wave amplitude is little, the liquid displacement amount is also few.
For guaranteeing the measuring accuracy of flow counter 9, air eliminator 7 is removed the air in the fuel oil, this air eliminator 7, because of miniaturization performance height, that is to say, use the Cyclonic air disconnector to be advisable, gas, liquid are separated by the centnifugal force of Cyclonic air disconnector.
From the outlet 6a of pump 6, along the cylindric pipeline direction inflow fuel oil of air eliminator 7, high speed revolution in cylindric pipeline 7a, the fuel oil that contains air that assemble in the centre in cylindric pipeline 7a is through pipeline 15 person who lives in exile's float bowls 16.The fuel oil that contains air separates air in float bowl with oil, fuel oil is 17 sides of returning inflow pump 6 by the road, and air is put into atmosphere through rotor valve 18.Thereafter, not aeriferous oil, the leading section outflow from cylinder road 7a flows into outlet side filter 8.
Shown in Figure 4, outlet side cylinder-shaped filter 8, be with fan-shaped filtering net 8a form cylindric after, what fender 8b constituted on its two end cap again.
This filter 8 is removed the assorted dirt in the oil, and the precision that has prevented flow counter is lowly side by side except fault, and the eddy current that flows into from air eliminator is also by rectification.Flowed into flow counter 9 by fluid after the rectification like this, because the straight sections of the inflow entrance of flow counter is short, guarantee measuring accuracy, the miniaturization of parts also becomes possibility.
Flow counter 9 is combined by two rotor 9a, that is to say to adopt salient angle formula flow counter to be fit to, and this flow counter is small-sized high precision positive displacement flowmeter, also is the flow counter that pulse free takes place.
Shown in Fig. 5,6, on the rotor chamber 9b of the rotor 9a that takes in flow counter 9, process and be used for fixing bolt hole 9d and the location indentations 9e that covers 9c.Have again, on lid 9c, be provided with the bearing 9g that the axle 9f of rotor 9a is inserted in supporting, in recess 9e, insert protuberance 9h, and be provided with bolt hole 9i.To be located at the recess 9e of the protuberance 9h insertion rotor chamber 9b that covers on the 9c, the axle 9f insertion bearing 9g with rotor 9a tightens fixed cap 9c with bolt 9j by screw 9d.
Utilize such protuberance 9h and recess 9e positioning and fixing lid 9c, thereby the axle 9f of rotor 9a is also correctly fixed, make flow counter have good assembly precision, the tooth engagement that also can not produce rotor is stuck.
The flow pulse transmitter 20 of flow counter 9 is the magnetite 9k that are provided with of axle 9f by flow counter 9, and detects the magnetic field of magnetite 9k and the magnetic field sensor 20a of delivery rate signal, and just the MR sensor constitutes.Have, the lid 20b of flow pulse transmitter 20 is by the 20c seal again.Lid 20b has been prevented the generation of the mal factors such as exchange rate of flow pulse transmitter 20 by the 20c seal like this.
When the axle 9f of flow counter 9 revolution, during magnetite 9k revolution, magnetic field sensor 20a detects the revolution of magnetite 9k, flow signal is input to the control setup that does not mark among the figure by signal wire (SW) 20d.
Shown in Figure 3, the outlet of flow counter 9 is connected with outlet 11 by control cock 10, and outlet 11 is connected with fuel oil supply nozzle by the pipe arrangement that end among the figure marks.
Because of on valve body 10a, being provided with the edge 10d of pressurization, the pressure of inflow entrance is kept suitably, the separating property of air eliminator 7 and the measuring accuracy of flow counter improve.
Have, valve body 10a is provided with reducing valve 21 again, and this valve 21 is made of valve body 21a and the spring 21c that pushes valve body 21a to valve seat 21b side closure valve with spring force.
Reducing valve 21, when the pressure in exit 11 raise, under pressure, fuel oil flowed back in the case 19, and the pipe arrangement in exit 11 and the damage of machine are reduced.
Illustrated embodiment is an example, is not the qualification content to technical scope of the present invention.
The effect of invention
1. have each equipment such as flowmeter and pump in the casing and be integrated, this combination weighing equipment can be little Type.
2. form pipeline after each parts connects in case, the streamline that flows into flowmeter is fixed, and makes metering Stable accuracy only needs to set an error in dipping.
3. the pipeline because of air separator and pump comes and goes complications, can control the pressure of higher cycle rate Vibration suppress to be disturbed, because of the rigidity height of pipeline, and area reducing and make hot-tempered sound low, strain is returned The multiple vibration attenuating that makes less flowmeter.
4. because pipeline shortens, reduced capacity, the pressure wave amplitude that produces because of cavitation is little, The replacement amount that liquid displacement causes also reduces.
5. flowmeter is the volumetric flowmeter by two rotor combinations, because of miniaturization, high accuracy. The pulse free phenomenon takes place.
6. the axle of the rotor of flowmeter is located at and covers, and lid is positioned by recess and protuberance, has guaranteed The position of armature spindle makes the rotor engagement accessible.
7. the lid of flowmeter rotor chamber is provided with the flow pulse sender unit, the lid of flow pulse sender unit Seal prevents that undesired factor from appearring in the flow pulse sender unit.
8. the filter in exit has rectified action, and the contracting of the straight sections of the inflow entrance of flowmeter Weak point can guarantee that measuring accuracy, miniaturization also become possibility.
9. because being provided with the control valve with boosting, to keep the suitable pressure of head piece, make air The air separation performance of separator and the measuring accuracy of flowmeter upwards improve and become possibility.
