As a kind of optimized technical scheme, described plunger pump is a three-cylinder plunger pump, and described jettison gear is provided with three sealing guide sleeves, three push rods, three crank throws, a support and a rotating shaft, and the same end of described three crank throws is all fixedlyed connected with described rotating shaft.
After having adopted technique scheme, the beneficial effects of the utility model are: simple in structure, compact, easy to use, reliable.When discharging water for the pump head body inner chamber, only need can finish, improve the working environment that pump head discharges water, reduce labor intensity the support equipment safe operation carrying on the operating grip, pressing down.This jettison gear structure also can be applicable to slurry pump and fracturing pump, can be applicable to the multi-cylinder plunger pump after the quantity of increase sealing guide sleeve, crank throw and push rod.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model embodiment's a structural representation;
Fig. 2 is an A-A sectional view among Fig. 1.
Among the figure: 1. pump head body, 2. plunger, 3. suction line, 4. support, 5. rotating shaft, 6. operating grip, 7. bearing pin, 8. crank throw, 9. sealing guide sleeve, 10. push rod, 11. spools, 12. springs.
Embodiment
As depicted in figs. 1 and 2, a kind of oil field plunger pump jettison gear.
The pump head body 1 of plunger pump has inner chamber, and plunger 2 to-and-fro motion realize the variation of cavity volume, have suction line 3 below pump head body 1, have spool 11 on the water intake between suction line 3 and the pump head body inner chamber, and spool 11 connects by spring 12.
Jettison gear of the present utility model comprises sealing guide sleeve 9, push rod 10, support 4, rotating shaft 5 and crank throw 8.Be provided with through hole in the bottom of suction line 3 and with the corresponding position of pump head body inner chamber, this through hole can directly adopt the former suction line bottom screw corresponding with the pump head body inner chamber, and sealing guide sleeve 9 is installed on this through hole; One end of push rod 10 passes the lower end surface that sealing guide sleeve 9 and suction line 3 inner chambers rely on spool 11 successively, and push rod 10 should contact with the lower end surface of spool 11 by end; Support 4 is fixedly installed on the plunger pump, and particularly, support 4 is fixedly installed on the suction line 3; Rotating shaft 5 is rotated and is located on the support 4, is provided with operating grip 6 in the end of rotating shaft 5; Crank throw 8 one ends are fixedlyed connected with rotating shaft 5, offer elongated slot on the other end, and push rod 10 is constrained in the elongated slot away from an end of spool 11, in this implementation process, are provided with bearing pin 7 at push rod 10 away from an end of spool 11, and bearing pin 7 is constrained in the elongated slot.
