The purpose of this utility model can realize by following technical proposal: a kind of bidirectional ram pump, comprise plunger, have the pump housing of two independent pump chambers, it is characterized in that, described pump chamber is connected with intake tunnel and the exhalant canal that is connected with the external world, described intake tunnel and exhalant canal place respectively are provided with and make the fluid one-way valve by intake tunnel, pump chamber, exhalant canal successively, described plunger two ends are stretched into respectively in two pump chambers, are connected with on described plunger to promote plunger reciprocating driving mechanism between two pump chambers.
The driving mechanism drive plunger is reciprocating between two pump chambers, and when the volume reducing of a pump chamber, another pump chamber must increase.Due to the existence of one-way valve, exhalant canal can only effluent fluid, and intake tunnel can only incoming fluid.Pump chamber reduces, and the fluid in pump chamber flows out from exhalant canal; Pump chamber increases, and the fluid of intake tunnel is inhaled in pump chamber.One-way valve is arranged on exhalant canal and intake tunnel place, does not have relatedly with one-way valve during the installation and removal plunger, has improved efficiency of assembling.
In above-mentioned bidirectional ram pump, described driving mechanism comprises motor and the coupling shaft that is connected with the rotating shaft of motor, described coupling shaft one end face bias is connected with an eccentric needle bearing, described plunger middle part offers recessed frame, and described eccentric needle bearing and recessed frame match and merge the drive plunger and pump.The driven by motor coupling shaft rotates, and is connected because coupling shaft and eccentric needle bearing are eccentric, so when eccentric needle bearing moves and plunger two side leans, makes plunger reciprocating.
In above-mentioned bidirectional ram pump, described driving mechanism comprises cylinder and the push rod that is connected with the push rod of cylinder, described plunger middle part offer can with the groove of push rod one end phase inlay card.The push rod moving linearly of cylinder drives push rod and plunger reciprocating.
In above-mentioned bidirectional ram pump, have guide pin bushing on the described pump housing, described guide pin bushing is enclosed within on plunger.Guide pin bushing is used for the restriction plunger, makes the plunger can be at the stationary axle upward sliding.
In above-mentioned bidirectional ram pump, described guide pin bushing has two and communicate with two pump chambers respectively, and described plunger two ends embed respectively in two guide pin bushings.All there is guide pin bushing at the plunger two ends, slide more steady.
In above-mentioned bidirectional ram pump, described plunger two ends are provided with annular groove, are arranged with seal ring on annular groove.Seal ring is used for the gap between sealed plunger and the pump housing or guide pin bushing, prevents that fluid from overflowing from the plunger sidewall.
In above-mentioned bidirectional ram pump, the described pump housing has an intake pipe and an outlet pipe, and described intake tunnel is communicated with intake pipe, and described exhalant canal is communicated with outlet pipe.Two pump chambers share same intake pipe and outlet pipe, and structure is more simple compact.
As preferably, in above-mentioned bidirectional ram pump, described plunger two ends also are arranged with steel ring, bowl flat board, leather cup, bowl suspender and fix by screw and plunger.Steel ring, bowl are dull and stereotyped, the bowl suspender all is used for fixedly leather cup, and leather cup can be made with materials such as rubber, nylon, coordinates the formation double seal with seal ring.
Compared with prior art, this bidirectional ram pump all has advantages of firm, easily manufactured, easy accessibility simple in structure, is arranged with seal ring and leather cup on plunger, makes the good sealing effect of plunger pump.
