Abstract
The utility model relates to a miniature portable centrifugal pump with small flow and low lift which is driven by DC motor which is accelerated by a gear box. The utility model is provided with a delivery chamber with guide vanes, and has high efficiency. The electric lines of the utility model has a function of converting AC 220 volt main power into DC 12 volt 24 ampere which is needed by DC electric motors, and the utility model can be connected with generators for cars to generate DC (14 volt, 24 ampere) to drive the utility model to work. The utility model is suitable for trucks which are provided with ordinary oil tanks and used to transport edible oil from oil depots to grain shops, and is suitable for the transportation of edible oil in remote areas which are lack of power supply particularly.
Description
The utility model relates to a kind of miniature oil pump that is applicable to two kinds of power supplys of alternating direct-current, is mainly used in transporting of edible vegetable oil, but also double as water pump or other purposes.It is one and drives the higher specific speed centrifugal pump that stator is arranged by the low-voltage direct motor, it is characterized in that physical dimension is little, and is in light weight, portable, is realized electric main or is used as power with the low-voltage DC that automobile current generator provides by control circuit.
Present domestic edible vegetable oil is transported to grain and oil store from oil depot, and majority is to transport with oil drum, and in general city and outlying small towns, with truck about the oil drum, its fluid waste and labor intensity are all very huge by manpower.Therefore oil tank progressively replaces oil drum, and oil drum is about to eliminate.How from car, fluid taken out and sends in the higher oil groove in position the grain shop? pump is the most general instrument.The existing multiple M﹠S of band pump fuel tank, but price is very expensive, can only transport as fluid.The county and at county level below grain and oil department purchase this fuel tank financial resources difficulty.And buy logical truck of a Daepori such as east wind automobile carrier, and lift a common oil tank again, to save a lot (can save more than ten thousand yuan) on its price.When bothering to see me out edible oil oil tank is not hung down, the utilization ratio of common truck can be given full play to.For this reason must pump of adapted.Mostly general pump is that with 380V ac power power supply or 220V electric main be power supply, and in view of present domestic power tense, especially outlying district, power failure is recurrent, and this causes difficulty for pumping fluid.
The utility model is that the requirement according to the grain distribution station designs, its purpose is, the both available alternating current 220V civil power of a kind of pump of minitype portable is a power, the 14V low-pressure direct current that automobile current generator on the available again automobile sends is a power, so that edible oil is pumped into the oil tank on the common truck and the oil pump on the car gone into high tank in the grain shop.
Feature of the present utility model is, on the direct current motor that automobile current generator institute output power (voltage and current) adapts, gearbox is installed, casing, and the impeller of the high rotating speed centrifugal pump of higher specific speed is installed on the output shaft of gearbox.Pump, gearbox and motor are to be connected in series and are integral, and the liquid stream runner that stator on spiral shell cover and the pump cover and impeller are formed helps reducing hydraulic loss.The control circuit that matches with it is a multiduty circuit, and it can provide DC electrical source to direct current motor M with the 220V electric main, can also receive the output terminal of automobile current generator, provides the energy with DC electrical source to pump.If the capacity of automobile storage battery descends, the also available 220V electric main of user is that power supply charges to storage battery.
Because the electric weight that automobile current generator can provide is very little, below 350W, considers the efficient that direct current is motor-driven, so the design parameter of this pump is as follows:
Specific speed: n
S=150 rotation speed n=4000 rev/min
Efficient: η=57% Yang Cheng H=6.5 rice
Flow: the Q=5.22 ton/hour=1.45 Kilograms Per Seconds
Automobile current generator: model JF132N, voltage E=14 volt, electric current I=24A.
Direct current motor: voltage rating E=12 volt, electric current I＜23A.
The design is made up of two parts, and first portion is motor and pump, as figure one.Second portion is an electric control system, as figure two.They are made two bodies respectively and are portable.
Consisting of of Fig. 1 motor and pump part: handle (1), gearwheel (2), casing (3), case lid (4), pump cover (5), pump case (6), delivery chamber (7), stator (8), blade (9), impeller (10), spiral shell cover (11), axle (12), small gear (13), direct current motor (14), support (15), leg (16), base plate (17) and corresponding seal ring, bearing, key and other standard piece.
It consists of Fig. 2 electric control system: power transformer (T), commutation diode (G

2Be in position 1, its A, B end is 14 volts of voltages of direct current of exportable full wave rectifier, and the DC electrical source of pump is provided.If use the automobile current generator electricity, (C, D) is connected with the output of automobile current generator the input end on the control box, just motor M can work, for the convenience of the user, works as K switch
1Close K
2Be in position 2, obtain one 12 volts one way rectifier VDC at A, B end, its electric current is 12 peaces, adjusts by potentiometer W, can charge to automobile storage battery, becomes a light charging equipment.
As oil pump, the design's mechanical parts material is cast iron and common iron, and also available cast aluminium replaces.Rubber seal is oil resistant rubber.
Motor and pump structure gross weight are less than 12 kilograms, and length overall is 320 millimeters.
This pump also can be made other usefulness by general service pump except that transporting as edible oil.
