Description

Metering fuelling machine

The utility model relates to a kind of improved metering fuel charger, has the advantages that flow is big, the accuracy of measuring is high, is specially adapted to petrol service station and unit oil depot and is truck conspicuity marking or other feed apparatus and refuel and use.

The existing metering fuel charger of China mostly uses the J-60A type, along with reform, opening and enlivening and modern requirement, so designed a kind of big flow fuel charger.

The purpose of this utility model be former J-60A type machine appearance profile size become less or basis of invariable on improve, provide the fuel charger that a kind of flow is big, the accuracy of measuring is high, to satisfy real needs.

The utility model is finished the work as follows: on former J-60A type machine basis, necessary improvement have been done in major part inside such as oil pump, oil separator, metering device, oil gun made this fuel charger reach 90 liters/minute flow, the accuracy of measuring reaches ± and 015%.1. in order to strengthen into oil drain quantity, reduce the pipeline flow resistance, reduce fluid pressure loss, increased metering fuel charger oil circuit access way, 2. in order to improve oil pump efficient and fuel feeding import degree of vacuum, the transformation of the way of the gluing sealing means between oil pump case and pump cover (1) is become with O shape rubber sealing (Fig. 1).To the overflow portion size, element has also been done necessary improvement (Fig. 2), and the buffering boss (3) of 6-8mm is set in valve body (2) bottom, and the natural frequency of vibration that makes the valve opening and closing balance spring is different from oil pump oil transportation frequency, avoided resonance to produce hydraulic noise, so that system stability work.3. oil separator, for guaranteeing to separate the gas effect, cut down finished cost, improve the life-span, make to be float (4) formula oil separator (Fig. 3) into check valve (5) formula oil separator, one-way valve structures (Fig. 4) is by valve body (6), and valve (7), air bleed hole (8), air extractor vent (9), copper ball (10) are formed.4. metering device; To have the pair of pistons of transferring the gauge rod mounting hole and improve the mounting hole (11) that becomes the inclined to one side axis of criss-cross (Fig. 5), other will also be done similar change to piston, make piston in twos symmetry reach four pistons work balances, improve the vibration that produces behind the flow to reduce.Need guarantee piston and plunger shaft and the precision-fit of transferring gauge rod and lining in addition, and the assembly technology requirement, to reduce internal leakage, guarantee the accuracy of measuring.5. oil gun, make corresponding fuel charger oil transportation amount and be 90 liters/minute oil gun (Fig. 6), adopt handle (13) location structure, by main valve (14), width of cloth valve (15) control oil transportation, spacer (17) is equipped with in rifle body inboard, and may command master, width of cloth valve refuel with the still middle flow of big flow respectively.Installing and locating spring (16) on gun barrel is stuck in during for oiling and prevents the oil gun slippage on the oil head.

The utility model is 90 liters of/minute metering fuel chargers, with J-60A type machine is that prototype converts, improve at inner member dimensional structures such as oil pump, oil separator, metering device, oil guns, and will advance the passage increase of footpath, oil extraction crossing, through the positive effect of having received on probation, other parts all can directly use J-60A type machine appliance, thereby has a good inheritance, can significantly reduce processing capacity and worker's folder amount mould, cost-cutting, measuring accuracy height, life-span is long easy to operate, the efficient height, now large quantities of operations, existing how tame manufacturer both at home and abroad orders goods.

Be elaborated below in conjunction with the utility model structure accompanying drawing:

Fig. 1 is the oil pump cover constructional drawing.

Fig. 2 is the valve pocket buffer table rank site plan of oil pump.

Fig. 3 is J-60A type fuel bowl oil separator figure.

Fig. 4 is oil separator figure.

Fig. 5 is that gauge rod structure of mounting hole figure is transferred in the inclined to one side axis of metering device piston criss-cross.

Fig. 6 is an oil gun.

With reference to diagram, starting oil pump begins to refuel, oil enters the check valve-type oil separator through a large amount of channel filters, when a large amount of gases enter check valve, because gaseous mass, viscosity are little, flow velocity is big and produce negative pressure, causes bead (10) still to be in the bottom, gas is discharged to air chamber then in atmosphere by air bleed hole (8) to air extractor vent (9), incidentally goes out micro oil and falls into the air chamber lower end.As oil with air bleed hole (8) when flowing through, because gas quality and viscosity are all bigger relatively, copper ball (10) is floated and rises to air bleed hole (8) to be located, block air bleed hole (8), a small amount of gas then is discharged in the air chamber through air extractor vent (9), this exhaust mode has avoided the fuel bowl disconnector to take place in this case to air chamber bleed phenomenon.Fluid just enters metering device after coming out from oil separator, register work demonstrates, output oil mass and fluid output speed, counting machine can show a volume read-out and accumulate volume read-out, and can recover on demand to measure separately after the zero-bit, flow through oil level indicator, flexible pipe of fluid enters oil gun ante-chamber (12), handles position fixing knob (13) and opens main valve (14), and fluid just passes through main valve (14) and is transported in the oil head to secondary valve (15).

Claims (3)

1, the utility model relates to a kind of new metering fuel charger, is made up of major parts such as oil pump, oil separator, metering device, oil guns, it is characterized in that:
