Description
Technical field
The utility model relates to a kind of liquid pump, and especially reciprocating volumetric pump belongs to the pump valve technical field.
Background technique
At present, known electric reciprocating pump, all reciprocating by reduction gearing mechanism drive crank-connecting rod or eccentric wheel driven plunger usually by motor, and by means of sucking one-way valve and discharging one-way valve generation hydraulic pressure and current.Above-mentioned existing electric reciprocating pump is all because the restriction of the retardation phenomenon of valve can't improve reciprocal time; In addition, being transferred medium contains impurity and also influences the valve seal reliability; And have that complex structure, volume are big, Heavy Weight, cost height, shortcoming that can only unidirectional liquor charging
Summary of the invention
The purpose of this utility model is: at the problem of above-mentioned existing electric reciprocating pump existence, a kind of valveless rotator type radial reciprocating pump is proposed, contain the executive component that produces eccentric reciprocating mechanism on the pump shaft as driving shaft, cancelled valve arrangement, the retardation phenomenon of having got rid of valve can improve the reciprocal time of pump; And eliminated because of impurity influences the valve seal reliability and then influences the shortcoming of pump performance, reach the purpose that designs simplification, volume-diminished, weight saving, cost reduce
In order to achieve the above object, the utility model proposes a kind of valveless rotator type radial reciprocating pump, it is by having the garden cylindrical inner chamber and the inner chamber runner being separated into the pump housing (5) of inhaling people chamber and discharge side by two cut waters, be contained in the rotator type liquid cylinder (7) in the cylindrical inner chamber of pump housing garden, radially make the piston or the piston assembly (6) of displacement in the garden post hole at liquid cylinder, make piston produce the eccentric reciprocating mechanism of displacement, pump shaft (1), pump cover (8) and axle envelope (2) are formed, its special way is: the relative pump shaft of rotator type liquid cylinder (7) axis (1) axis has a throw of eccentric, contains eccentric reciprocating executive component on the pump shaft (1).
The axle head that the eccentric to-and-fro motion executive component of above-mentioned valveless rotator type radial reciprocating pump can be a pump shaft is made tablet, is inserted in the corresponding translot of piston (6) waist.
The eccentric reciprocating executive component of above-mentioned valveless rotator type radial reciprocating pump also can be made up of pump shaft (1) and square slider (10), and pump shaft and slide block link with key, and slide block is embedded in the corresponding groove of piston (6) waist.
The eccentric reciprocating executive component of above-mentioned valveless rotator type radial reciprocating pump also can be that eccentric shaft (11) is housed on the pump shaft (1), and the axle that turns on the eccentric shaft (11) is inserted in the post hole, the corresponding garden of piston waist eccentric shaft (11) and pump shaft key joint.
The described piston of valveless rotator type radial reciprocating pump (6) of above-mentioned three kinds of structures can be that plunger adds barrier film.
Because valveless rotator type radial reciprocating pump of the present utility model has been cancelled the valve arrangement of conventional reciprocating pump, also rotation synchronously of rotator type liquid cylinder during the pump shaft rotation, make piston reciprocating while rotating with the rotator type liquid cylinder by eccentric reciprocating mechanism, the twice throw of eccentric is the running length of reciprocating motion of the pistons; Piston at the upper half of each rotation from inhaling people's chamber inspiration liquid, and at lower half to the discharge side drain.New structure has been got rid of the retardation phenomenon of valve, can improve the reciprocal time of pump, and has eliminated because of impurity and influence the valve seal reliability and then influence the shortcoming of pump performance; Designs simplification, volume-diminished, weight saving, cost reduce, efficient improves thereby make: except that having kept the good self-priming performance of conventional reciprocating pump, can also reach gas, liquid, husky mixing and fail, also can carry suspended matter, fibre object and viscous liquid; And increased when motor only reverses can two-way liquor charging new function.
