Pump pump body is breathed to magnetic force

The utility model relates to a pump pump body is breathed to magnetic force, a serial communication port, it has the one or more cavity to distribute in the pump body, be provided with on the wall ofcavity sliding rail structure with corresponding piston on slider cooperation work. Be provided with the electrode on the sliding rail structure of cavity, the electrode with corresponding binding post electricity on the pump body surface is connected, electrode and corresponding piston electrode cooperation, binding post has two pairs at least, and one of them is to corresponding constant voltagepower supply, and a pair of or how many are to corresponding alternating voltage power in addition. The one end of cavity is provided with the oil inlet, and the other end is provided with the oil -out, oil inlet and oil -out department all are provided with the check valve. The utility model provides a pump body, adopt slide rail slider structure, make piston and pump body contact diminish, notonly because frictional hea
