Description

A kind of electromagnetic plunge pump
Technical field
It the utility model is related to field of hydraulic equipment, and in particular to a kind of electromagnetic plunge pump.
Background technology
Plunger pump is an important device of hydraulic system.Plunger pump generally comprises cylinder body, and one end of cylinder body is connected with column Plug, the other end of cylinder body are connected with unidirectional liquid valve, and cylinder body is communicated with unidirectional liquid feed valve, and unidirectional liquid feed valve is located at unidirectional liquid valve Between plunger.It is mainly moved back and forth by plunger in cylinder body, makes the volume of seal operation cavity volume change to come in fact Existing oil suction, pressure oil.Plunger pump has the advantages that rated pressure is high, compact-sized, efficient and flow-rate adjustment is convenient.
At present, mostly it is that rotating machinery power is converted into the past of plunger with toggle or swash plate piston shoes mechanism etc. Complex line machine power.But since the connecting rod swing of toggle in system causes piston lateral force bigger, not only Mechanical efficiency loss, heavy wear and extra heat load between piston and casing wall, plunger and casing wall are caused, while crank connects Linkage stress intensity is big, and the frictional dissipation at each hinge joint is serious, and the unevenness of system operating is big.Most serious of all by In system capacity conversion, transfer route length, by multiple intermediate transfer links, it is low to cause conversion transmission efficiency, energy dissipation Seriously, the problems such as system complex, heaviness, production cost and high, seriously polluted operating cost.
Utility model content
The utility model is intended to provide a kind of electromagnetic plunge pump, with solve in the prior art energy conversion transmission efficiency it is low, Complicated bulky technical problem.
In order to solve the above-mentioned technical problem, the utility model provides following scheme:A kind of electromagnetic plunge pump, including body, ' work ' font cavity is equipped with the body, ' work ' the font cavity includes upper cavity, middle cavity and lower chamber, the epicoele The left end of body and the right end of lower chamber are equipped with the cover of electromagnetic coil and Motionless electromagnetic coil, and the right end of the upper cavity is with The left end of cavity is equipped with oilhole, and the oilhole is respectively connected with unidirectional liquid feed valve and unidirectional liquid valve, is equipped with the upper cavity First plunger, the left end of first plunger are equipped with permanent magnet, the second plunger are equipped with the lower chamber, second plunger Right end also is provided with permanent magnet, and first plunger and the second plunger are connected with connecting rod jointly, and the connecting rod is in described In cavity.
The operation principle of this programme:Electromagnetic coil produces magnetic field when being powered, and attracts the column below this coil as magnet Permanent magnet beyond the Great Wall is moved to the geometric center of electromagnetic coil, so as to drive plunger to move, in the present solution, first giving the first plunger pair The electromagnetic coil answered is powered, so as to drive the first plunger to be moved to the geometric center of the electromagnetic coil, due to the first plunger and the A connecting rod is connected between two plungers jointly, so the second plunger is also with the first plunger synchronizing moving, when the first plunger When being moved to left stop (i.e. the first plunger is moved to the left position when touching cover) with the second plunger, the electromagnetic coil at this time Power-off, the corresponding electromagnetic coil of the second plunger are powered, and to one electromagnetic force to the right of permanent magnet on the second plunger, drive second Plunger moves right, and the first plunger also synchronously moves right, and when reaching right stop, (i.e. the second plunger, which moves right, touches cover When position) when, electromagnetic coil power-off, and the corresponding electromagnetic coil of the first plunger has energization, and thus repeatedly, reaching makes first The effect that plunger and the second plunger move repeatedly in body;And the right end of upper cavity and the first plunger seal and be slidably connected, So the working volumes of a sealing are formed between the right end of upper cavity and the first plunger, therefore when the first plunger moves repeatedly Change the volume size of the seal operation cavity volume, and then realize oil suction and oil extraction work, similarly, the left end of lower chamber and the second column Also the working volumes of a sealing are formed between plug, the second plunger changes seal operation cavity volume volume when moving repeatedly is big It is small, and then realize oil suction and oil extraction work.
The beneficial effect of this programme:In the present solution, the electricity between the magnetic field produced using electromagnetic coil energization and permanent magnet Magnetic force, to drive the first plunger and the second plunger motion, since the first plunger and the second plunger are fixed together by connecting rod, So the first plunger and the second plunger are synchronized with the movement, and because the permanent magnet on the first plunger and the second plunger and electromagnetic coil are located at Opposite one end, so the first plunger and the second plunger move reciprocatingly in cylinder body, so as to change the body of seal operation cavity volume Product size, realizes that oil suction and oil extraction work, and in the work process, electromagnetic energy is directly delivered on the first plunger and the second plunger, There is no intermediate transfer structure, so this plunger pump energy transfer efficiency is high, simple in structure.
Further, the cover is equipped with cushion pad in its one side adjacent with the first plunger and the second plunger.Due to When one plunger and the second plunger motion are to low order end or high order end, permanent magnet can be contacted with cover, can cause for a long time permanent magnet by To abrasion, so setting cushion pad to avoid permanent magnet from being worn.
Further, the connecting rod is equipped with cushion.Due to connecting rod as the first plunger and the second plunger are done back and forth It may be collided during movement with cylinder body, cause cylinder body and connecting rod to be damaged, so setting cushion effectively to solve the problems, such as this.
Further, it is equipped with gap between the middle cavity and the first plunger and the second plunger.Thus be avoided that the first plunger and Second plunger contacted with the side wall of middle cavity and caused by abrasion.
Further, the unidirectional liquid feed valve is connected with a feed liquor house steward jointly, and the unidirectional liquid valve is connected with jointly A piece go out liquid house steward.So set the oil of the oil for discharging upper cavity and lower chamber or suction to concentrate, improve work efficiency.
