Abstract
The utility model relates to a portable electric oil well pump which may use oil or water and is applied to the field of electric tools. The utility model is designed aiming at solving the rather complex structure of existing products of the same sort. The design key points are that a motor connecting board is connected with the bump through a hexagon socket head cap screw, a D shaped nut and a plain cushion; doctor blades and a doctor blade back shaft are arranged in a rotor to rotate around an eccentric sleeve, the upper end and the lower end of the rotor are fixed by sealing copper washers and rotate, the four doctor blades are divided into two groups, one ends of the four doctor blades rotate around the doctor blade back shaft which has the same shaft with the eccentric sleeve, and the other ends move along the eccentric sleeve, and the parts of the two groups of doctor blades, which extending out from the rotor, undergo linear alternate motions under the action of the middle doctor blade back shaft and that of the rotor. The utility model solves the technical problem that the structural design of similar products is not so reasonable. Particularly, the adoption of the eccentric doctor blade structure makes the processing of parts easy. Thus, the electric oil well pump has the advantages of compact structure, small volume, easy carrying and convenient operation.
Description
Technical field
The utility model relates to field of power tools, is the portable electric defueling pump of a kind of oil or water dual-purpose.
Technical background
At present, manually oil well pump, suction pump are widely used in each side such as automobile, engineering machinery, corrective maintenances.But manually oil well pump ubiquity rate of pumping is slow, oil pump capacity is low, the shortcoming that labor intensity is big.Especially at the station that unfixed point refuels, the operator gets round-the-clock on-the-spot service, seems very arduous.A electronic oil pumping, the water pump that occur on the present overseas market, its structure are comparatively complicated, and processing cost is higher, and frictional force is bigger, the energy consumption height, and efficient is lower.
Summary of the invention
The utility model will overcome above-mentioned deficiency, and purpose is to provide a kind of portable electric defueling pump to related domain, make its structural design that can solve like product owe rational technical problem.The purpose of this utility model realizes by the following technical solutions.
A kind of portable electric defueling pump, this oil well pump mainly are made up of dc motor assembly, output tube or supplying tube, check valve body, rotor, scraping blade, eccentric bushing, scraping blade back shaft, outer casing upper cover, outer casing base, and the main points of technological scheme are:
The connecting plate for electric motor of dc motor assembly is connected by hexagon socket head cap screw, D nut, plain cushion with the pump housing.Press switch block, the actuating of relay, the motor of the dc motor assembly of connection is started working.Scraping blade, scraping blade back shaft are contained in the rotor, coexist with rotor one under the drive of motor and move in the eccentric bushing, outside framework oil seal, rotor seal ring, go up sealing cushion for cover and play seal action.Open bonnet, power line is put into lid with coiling.Scraping blade, scraping blade back shaft are assemblied in the rotor, rotate flexibly around eccentric bushing, and the two ends up and down of rotor are fixed with the sealed copper packing ring and rotated flexibly.Four scraping blades are divided into two groups, scraping blade one end is along the scraping blade back shaft in rotation process, this scraping blade back shaft is coaxial with the interior circle of eccentric bushing, the other end moves along the eccentric bushing inwall, the length that two groups of scraping blades stretch out rotor constantly changes, cause that the volume between eccentric bushing and the rotor surface constantly changes, liquid is constantly sucked and is discharged.
The output tube of described portable electric defueling pump or supplying tube are connected with the pump housing, and the one-way valve seal ring is housed in the check valve body, and check valve spring is close in the return port of the pump housing, play a protective role when system's overcurrent.Stop up or circulation when smooth when pipeline breaks down, will open check valve body this moment, checks inner circulatory condition, and whole circulation system is not destroyed.Constitute housing by outer casing upper cover, outer casing base, bonnet, the pump housing assembly after the assembling is buckled into wherein.Electronic oil well pump is equipped with trailing wheel and preceding universal wheels, makes its random dragging, and is provided with handle at outer casing upper cover, extracts with convenient.
By above-mentioned technological scheme, overcome the deficiency of known technology, solve the like product structural design and owed rational technical problem.Especially adopt eccentric to scrape chip architecture, part is easy to processing.Make this electronic oil well pump possess the performance that compact structure, volume are little, be easy to carry about with one, be convenient to operate.

Embodiment
Mode of execution is an example with the work of this portable electric defueling pump.Connect power supply, press the button of switch block 36, by the contact of relay 34, dc motor assembly 26 is started working, drive rotor 13, scraping blade 14 are made circumferential running, and scraping blade is done linear reciprocating motion under the effect of centre seal back shaft 12 in rotation process; Because the motion of scraping blade causes the continuous variation of volume, oil plant will constantly be inhaled into, discharge in the rotation process.Scraping blade back shaft 12 is under the seal action of outside framework oil seal 22, rotor seal ring 20, loam cake seal ring 3, one side of eccentric bushing 15 forms vacuum, liquid is inhaled into continuously, and discharges by the opposite side of eccentric bushing, and is realized the shuttling movement of oil by output tube or supplying tube 6.When oil gun that electronic oil well pump connected is closed or pipeline when blocked, liquid can back down check valve spring automatically, opens check valve body 10, the safety of protection pump chamber operational system.This portable electric defueling pump key components and parts adopts stainless steel to make, and the part surface of motion mutually is through special processing, has promptly wear-resistingly reduced frictional force again, thereby has improved efficient.Realize both can pumping, the function that can draw water again, the latter washes vehicle, cooperates the cleaning of different rifle heads to different parts.The superpressure that is provided with this electronic oil well pump refluxes and is provided with, and realizes the automatic adjusting of pressure, uses safer.
