The technical solution of the utility model
The combined simple plunger pump that the utility model is alleged is provided with skeleton symbol plunger valve crowd in the pump housing.Described skeleton symbol plunger valve crowd is made up of a plurality of plunger valves, and each plunger valve mainly is made up of valve rod and valve body again, and valve body wall is provided with the oil extraction inclined hole, and the oil outlet of valve body connects pump housing oil pocket; The valve body bottom is provided with oil-sucking hole; Said skeleton symbol plunger valve crowd's combination or for single group or be above many groups of two groups and two groups; Skeleton symbol plunger valve crowd for many groups, respectively organize skeleton symbol plunger valve crowd and be connected with pump housing pto successively.
The further technical solution of the utility model
Said skeleton symbol plunger valve crowd is many groups, and the structure of each group is identical.
Said many group skeleton symbol plunger valve crowds' combination is provided with connecting plate between each group, will organize skeleton symbol plunger valve crowd more and connect into the whole pump housing.
Said skeleton symbol plunger valve crowd's oil extraction inclined hole connects oil drain passage, leads to pump housing oil pocket, and pump housing oil pocket passes to total oil exit pipe; Its lower end of oil extraction inclined hole communicates with the valve body chamber, and the place of communicating is provided with boss, is placed with steel ball on the boss, and the steel ball footpath is greater than the boss internal orifice dimension.
The oil-sucking hole that said skeleton symbol plunger valve crowd's valve body bottom is provided with is connected with the pump externally mounted fuel tank, and oil-sucking hole is provided with concave station, is placed with steel ball on the concave station, and the steel ball footpath is greater than the concave station internal orifice dimension; And the position, hole of said oil-sucking hole is provided with near valve body wall.
Said connecting plate is provided with the filler opening that is connected with the pump externally mounted fuel tank.
Said many group skeleton symbol plunger valve crowds' combination, its skeleton symbol plunger valve crowd bottom that is positioned at one group of below has the pump fuel tank; Fuel tank is connected with the pump externally mounted fuel tank in the said pump.
The beneficial effect of the utility model
(1) the utility model has been simplified the concrete structure of existing axial columns plug valve; Also utilize same pto that many group skeleton symbol plunger valve crowds are set; Obviously increased axial piston pump oil pump capacity, strengthened oil pressure; Make plunger pump reaching under identical oil pump capacity, the oil pressure parameter prerequisite, reduced power consumption.
(2) the skeleton symbol plunger valve crowd of the utility model has removed rapid wear assemblies such as spring, and maintenance rate is low, easy for installation, long service life, and performance is safe and reliable.
Description of drawings
Accompanying drawing 3 is organized the structural representation that skeleton symbol plunger valve group closes for the utility model more.
Embodiment
Like Fig. 1, shown in 2,
The alleged skeleton symbol plunger valve crowd 1 of the utility model is the center with the power input shaft 2 (containing bearing 21) of pump housing power equipment (like motor, diesel engine, petrol engine etc.), is provided with the plunger valve 3 laid in orientation such as a plurality of and (only representes corresponding a pair of two among Fig. 1; The colony that has represented five pairs of ten plunger valves among Fig. 2), each plunger valve mainly is made up of valve rod 31 and valve body 32.Swash plate 22 rotations that are connected with power input shaft 2 are pressed on the valve rod of each plunger valve.Valve body wall is provided with oil extraction inclined hole 33, and the oil extraction inclined hole connects the oil pocket 5 that oil drain passage 35 leads to the pump housing, and oil pocket leads to the hydraulic equipment (not shown) through total oil exit pipe 4; The bottom of valve body is provided with oil-sucking hole 34.Oil extraction inclined hole lower end is provided with boss 331 with the place of communicating, valve body chamber, is placed with oil drainage hole steel ball 332 on the boss; Oil-sucking hole 34 is provided with concave station 341, is placed with oil-sucking hole steel ball 342 on the concave station.
It is as shown in Figure 3,
Skeleton symbol plunger valve crowd 1 among the figure is three groups, is that the center is provided with pump housing power input shaft 2 successively, is provided with connecting plate 6 between each group, will organize skeleton symbol plunger valve crowd more and connect into the whole pump housing.Connecting plate is provided with the filler opening 61 that is connected with the pump externally mounted fuel tank, and it is positioned at that the bottom of the one group of skeleton symbol plunger valve crowd valve body in below has pump fuel tank 7, and passes through the filler opening and the pump externally mounted fuel tank (not shown) of connecting plate.
Below in conjunction with accompanying drawing, the working procedure of brief description the utility model plunger valve:
Respectively organize plunger valve crowd's plunger rod end in this plunger pump; Through be positioned at its top pto and drive swash plate 22 runnings; Make plunger valve 311 times set springs 312 of valve rod cap or be lax shape, or be impaction state, as: the spring of left side valve is for compressing the shape shape that relaxes among the figure; The spring of the right valve is lax shape, is provided with chamfering man-hour because boss or concave station add, thereby steel ball drops on oil drainage hole or the oil-sucking hole and all excellent sealing performance can be arranged.When the valve rod of the right valve moved up, oil-sucking hole steel ball 342 was picked up, and oil-sucking hole sucks fluid; The valve rod of left side valve is to bottom offset, and oil-sucking hole steel ball 342 is adjacent in the oil suction aperture, and the fluid in the valve pocket is the communications centre oily inclined hole steel ball 332 that begins to rehearse then, and the fluid in the valve pocket is discharged from the oil extraction inclined hole, gets into pump housing oil pocket and oil outlet tube.Because each group plunger valve crowd's plunger valve to-and-fro motion again and again, high pressure oil exports the engineering hydraulic equipment to from oil outlet tube to make the oil outlet of plunger pump have continuously.
To sum up, the utility model can reach the goal of the invention of expection.
