Its purpose of multi-cylinder plunger pump that the utility model proposes just is to make it to have higher working efficiency, has simple in structurely simultaneously, is easy to manufacturing and characteristics easy to maintenance.
The utility model is finished the technological scheme that goal of the invention takes: vertical two rows are provided with a plurality of plunger cases hole on the cylinder body of pump, and each plunger case side that has a plunger is provided with fuel feeding application chamber and oil extraction application chamber and communicates with the plunger case inner chamber respectively on the cylinder body of pump simultaneously; The two organ timbering plug cylinder central authorities below of vertically arranging is provided with the oil extraction through hole, is provided with oil supply gallery and is communicated with fuel tank below plunger case; Be that every organ timbering plug cylinder bottom is provided with an oil supply gallery and is communicated with fuel tank, to the plunger case fuel feeding of correspondence.
The fuel feeding application chamber of each plunger case side is arranged on the cylinder body of pump, in spring and oil-feed check valve are arranged, check valve under spring action between oil supply gallery and plunger case, stop oil to enter plunger case, during the plunger upward stroke, the suction that the plunger below produces picks up the oil-feed check valve, and open port sucks oil in the plunger case; Spring and oil extraction check valve are arranged in the oil extraction application chamber, the oil extraction check valve under spring action between plunger case and oil extraction through hole, stop oil to enter the oil extraction through hole, plunger is when down stroke, oil in the plunger case backs down the open port of check valve of oil extraction application chamber, and oil enters oil drain passage, discharges through pipeline, when acting on press machine, lead to above the hydraulic machine piston face, provide pressure oil to it.
The power section of plunger mainly contains the gearbox of motor and large and small gear and in the output shaft of gear-box end one eccentric wheel is set, the big connecting rod the other end that one end is connected on the eccentric wheel throw of eccentric is connected with the arm of couple lower end of T font effect axle, and the two ends of effect axle are connected to two plunger upper ends of vertical two rows by small rod.During the power section action, big connecting rod one end is with eccentric crop rotation circular movement, and the other end is a straight line motion, and the two ends of effect axle move up and down under the effect of big connecting rod, and the upper end that the small rod at two ends drives plunger again makes its motion up and down reciprocatingly.
An outstanding supporting axle play supporting role in order to be connected with gearbox casing at the intersection point place of effect axle.
The plunger case of its a plurality of arrangements of multi-cylinder plunger pump of the present utility model sets on the cylinder body of pump, and plunger and power section all are arranged on outside the cylinder body of pump, and plunger is pressed into the plunger case hole so that cylinder sleeve is equipped, and total is comparatively simple, is easy to manufacturing and is convenient to maintenance; Working efficiency is higher and can make its suitable requirements of one's work according to the size and the big or small quantity of selecting be provided with plunger of pressure of work discharge capacity.
Accompanying drawing 1 is the utility model embodiment's a cross-sectional view.
The embodiment who provides is in conjunction with the accompanying drawings further specified the utility model structure:
Structure sets a plurality of plunger cases of vertical two rows hole on the cylinder body of pump as shown in drawings, and the plunger case hole is equipped to be pressed into cylinder sleeve, is convenient to repair or change; Each plunger case side that has a plunger 5 is provided with oil suction application chamber and oil extraction application chamber and communicates with plunger case inner chamber 10 respectively; The two organ timbering plug cylinder central authorities below of vertically arranging is provided with oil extraction through hole 14, is provided with oil supply gallery 8 and is communicated with fuel tank below plunger case, and promptly every organ timbering plug cylinder bottom is provided with an oil supply gallery that is communicated with fuel tank 8, to the plunger case fuel feeding of correspondence.The fuel feeding application chamber of plunger case one side is arranged on the cylinder body of pump, in spring 15 and oil-feed check valve 6 are arranged, check valve can adopt steel ball, the oil extraction application chamber also is arranged on the cylinder body of pump, in spring 15 and oil extraction check valve 12 are arranged, check valve also can adopt steel ball.
The power section of plunger mainly contains the gearbox of motor and large and small gear, at output shaft of gear-box is that the Large Gear Shaft During end is provided with eccentric wheel 1, connect big connecting rod 2 on eccentric wheel throw of eccentric point, the big connecting rod the other end is sold in the 3 times stomidiums of the arm of couple that are through T shape effect axle 7 with unit and is connected; The two ends of effect axle 3 are connected to two plunger upper ends at vertical two row two ends by small rod 4.
Every horizontal two of the plunger that vertical two rows arrange is that one group of its upper end is provided with small rod 4, and be connected to the two ends of effect axle 7, and upper end of its effect axle 7 is worn axle by the middle part and all is connected with the arm of couple 3 of plunger power section, organizes pump oil suction and provide pressure oil to the oil extraction through hole of plungers thereby the straight line motion of the big connecting rod 2 ends drive arm of couple 3 has when moving more.The plunger case top of the pump housing is provided with leakage-preventing oily passage (hole), and the plunger cylinder below is provided with accepts to reveal fuel tank.
