Abstract
The utility model relates to a piston pump driving device, belonging to the liquid transferring piston pump technical area, characterized in that a main bush is provided with a fitted slipper; a chute, on which a chock is mounted, is produced on the outer diameter of the slipper; an open disc is mounted in the groove on the outer diameter of the main bush; the chock is connected with the open disc through a pin roll and the open disc is connected with a connecting rod through bearings, a gland is provided on the slipper; and one end of a screw for supporting the bearing and adjusting the travel is mounted in the chamber with another end of the screw provided with thread. The utility model has the advantages of long service life, high measuring accuracy and reducing the operation noise of the piston pump.
Description
Technical field: the utility model belongs to the plunger pump technique field that liquid is carried usefulness, is specifically related to a kind of plunger pump driving device.
Background technique: the drive unit of existing plunger pump is by the collision of the eccentric cam on main shaft crank shaft, regulates crank shaft and cam spacing size, realizes that crank shaft drives the plunger rod to-and-fro motion, its shortcoming is, operational noise is big, and parts are easy to wear, and measuring accuracy is low.
Summary of the invention: the purpose of this utility model provides a kind of long service life, and the measuring accuracy height can reduce the plunger pump driving device of work noise of plunger pump.
The technical solution of the utility model is: a kind of plunger pump driving device, by collar bush, the worm gear that collar bush downside cylindrical is provided with, form with the worm screw that the motor shaft of worm wheel is provided with, it is characterized in that: be provided with the slide block that matches with it in the collar bush mesopore, the slide block cylindrical is provided with a skewed slot, is provided with chock in the skewed slot; Be provided with opening disk in the groove on the excircle of main axle sleeve; By pin chock, opening disk are connected in one, opening disk links to each other with connecting rod by bearing; Upper end of slide block is provided with gland, is provided with bearings in the chamber and transfers stroke screw rod one end, and the screw rod the other end is provided with screw.
Owing to adopt technique scheme, regulate the stroke screw rod, slide block moves, the axis that chock in the skewed slot on the slide block drives the relative collar bush of opening disk on the pin produces skew, when opening disk is rotated with collar bush, drives the connecting rod that joins with it plunger bushing is moved reciprocatingly, absence of collision between the parts, thereby having long service life, the measuring accuracy height can reduce the advantage of work noise of plunger pump.
Description of drawings: come the technical solution of the utility model is elaborated below in conjunction with the drawings and specific embodiments.Fig. 1 is a structural representation of the present utility model.Fig. 2 is the A-A broken section enlarged view of Fig. 1.
Embodiment: with reference to figure 1, Fig. 2.A kind of plunger pump driving device, by collar bush 1, the worm gear 2 that collar bush 1 downside cylindrical is provided with, form with the worm screw 3 that the motor shaft of worm wheel is provided with, be provided with the slide block 4 that matches with it in collar bush 1 mesopore, slide block 4 cylindricals are provided with a skewed slot 5, are provided with chock 6 in the skewed slot 5; Be provided with opening disk 7 in the groove on collar bush 1 cylindrical; By pin 8 chock 6, opening disk 7 are connected in one, opening disk 7 links to each other with connecting rod by bearing; Slide block 4 upper ends are provided with gland 9, are provided with bearings in the chamber and transfer stroke screw rod 10 1 ends, and screw rod 10 the other ends are provided with screw 11 and get final product.
