Abstract

The utility model provides a plunger pump which is characterized in that the cylinder body is sheathed with a coil group which is electrically connected with a control circuit, wherein, the cylinder body is made from non-magnetic material; a plunger sliding in the cylinder body is made from soft magnetic material. Because the cylinder body of the plunger pump is sheathed with the coil group, the plunger generates reciprocating movement under the action of magnetic field force, and thus the rotating electric machine and the crankshaft connecting rod driving mechanism which are matched with the plunger are omitted. The utility model, the power saving rate of which reaches above 50%, has the advantages of small size, simple structure, easy manufacture and maintenance, low cost and high mechanical efficiency.

Description

Plunger pump

The utility model relates to a kind of plunger pump, main by cylinder body, be fastened on that cylinder body end has the cylinder cap of suction valve and expulsion valve, the piston that slides in the cylinder body is formed.Belong to the plunger pump technique in the material transmit machine field.

Present plunger pump is that the electric rotating machine outputting power is promoted reciprocating motion of the pistons by crankshaft ﹠ connecting, sometimes in order to satisfy certain job requirement, also between motor and crankshaft ﹠ connecting, add speed change gear, therefore not only to exist mechanical efficiency low for existing plunger pump, and make the supporting with it big deficiency of motor power consumption, but also exist the deficiency that volume is big, manufacturing process is complicated, cost is high, maintenance load is big.

The purpose of this utility model be exactly provide at the deficiency in the above-mentioned plunger pump a kind of simple in structure, mechanical efficiency is high, the plunger pump of saving power.

The utility model is to design according to the principle that toroidal winding energising produces magnetic field and magnetic or the body magnetic field force induced effect in toroidal winding that is magnetized produces motion.Change and pace of change by the magnetic polarity that adopts different control circuits just can control toroidal winding, thereby realize control magnetic or the movement velocity of the body that is magnetized and the purpose of reciprocating frequence.

The purpose of this utility model realizes by following technical measures: the coil groups that suit is electrically connected with control circuit on the cylinder body, and wherein cylinder body is by no magnetic material, and the piston that slides in the cylinder body is that soft magnetic material is made.

Control circuit is controlled the variation of the size and Orientation of voltage in each coil groups, electric current successively during work, makes each coil groups two ends magnetic polarity conversion thereupon, thereby attracts or repel piston body and make it make axially reciprocating along inboard wall of cylinder block.

The utility model since on plunger pump cylinder body suit coil groups, make piston under the effect of magnetic force, to-and-fro motion take place, thereby electric rotating machine supporting and crankshaft-linking rod drive mechanism have been saved with it, have volume little, simple in structure, make and maintenance easily, the advantage that cost is low, mechanical efficiency is high, its power saving rate is up to more than 50%.But technological scheme provided by the utility model, can make the plunger pump of pump gas transmission body medium, the also plunger pump of pump transfusion fluid medium or mixed medium.
