Abstract
The utility model relates to a kind of plunger pump modified return plates, including a backhaul disc main body, the backhaul disc main body is a disc-shaped structure, in the through-hole that there is the medium position of backhaul disc main body an appearance transmission shaft to pass through, in the upper mounting hole for holding piston shoes installation for being also equipped with several distributions of shape in a ring around through-hole of backhaul disc main body；The two sides of the circumferential end surfaces of the backhaul disc main body are inclined-plane, and the inclined direction on inclined-plane is gradually to tilt to the centerline direction of the circumferential end surfaces of backhaul disc main body from the center of backhaul disc main body to the end direction of backhaul disc main body.Utility model has the advantages that for the end face of backhaul disc main body, it is the mode on inclined-plane by using two sides, so that return plate is when being swung, the end of return plate will not contact inclined plate or cylinder ends in advance, the hunting range for allowing for return plate in this way is bigger, to increase the stroke range of plunger.
Description
Technical field
The utility model relates to a kind of plunger pump, in particular to a kind of plunger pump modified return plate.
Background technique
Hydraulic pump provides a kind of Hydraulic Elements of fluid under pressure for hydraulic drive, is one kind of pump.Its function is dynamic
The mechanical energy of power machine (such as motor and internal combustion engine) is converted into the pressure energy of liquid.Influence the service life factor of hydraulic pump very
It is more, in addition to pumping itself design, other than manufacture factor and it is some with pump using the selection of related elements (such as shaft coupling, oil filter),
Operation etc. during trial run and run also has relationship.The working principle of hydraulic pump is the variation that movement brings pump chamber, thus
Compression fluid makes fluid have pressure energy.
Plunger is the core component in plunger pump, is used cooperatively with plunger part.Plunger has a pocket, plunger circle
Head is placed in the pocket, realizes that plunger round end carries out rotational motion in pocket.And plunger ports are open, therefore column
To cooperate closing between plug and plunger round end, plunger round end is shunk and realizes gap rotating function in plunger.
Currently, traditional plunger pump structure, generally includes a plunger pump shell, it is equipped with one in plunger pump shell and stretches
Transmission shaft outside plunger pump shell out is successively set with from end part of driving shaft to center transmission shaft direction in the two sides of transmission shaft
Inclined plate, return plate, cylinder body, oil distribution casing are further sleeved with the piston shoes of several distributions of shape in a ring on return plate, are located on cylinder body
It is also equipped with the plunger for corresponding cooperation with piston shoes around transmission shaft, has on cylinder body and holds plunger insertion and reciprocating movement
Groove, while also having in groove across cylinder body and the oil duct that is connected with oil distribution casing, thus by hydraulic in oil duct
The reciprocal circulation of oil drives piston shoes to realize that plunger moves back and forth in groove to push inclined plate to be moved.In above-mentioned knot
In structure, for return plate, return plate in traditional structure is the disk structure of a standard, such structure, so that plunger
Push piston shoes or pull piston shoes when, the end of return plate can touch in advance the end face of back incline or cylinder body, and cause plunger without
Method is further continued for work, i.e. the stroke range of plunger compares small.
Utility model content
The technical problem to be solved by the present invention is to provide the plunger pump use that one kind can increase the stroke range of plunger
Modified return plate.
In order to solve the above technical problems, the technical solution of the utility model are as follows: a kind of plunger pump modified return plate,
Innovative point is: including
One backhaul disc main body, the backhaul disc main body are a disc-shaped structure, have one in the medium position of backhaul disc main body
Hold the through-hole that transmission shaft passes through, it is sliding in the upper appearance for being also equipped with several distributions of shape in a ring around through-hole of backhaul disc main body
The mounting hole of boots installation；
The two sides of the circumferential end surfaces of the backhaul disc main body are inclined-plane, and the inclined direction on inclined-plane is from backhaul disc main body
Center to backhaul disc main body end direction gradually to the centerline direction of the circumferential end surfaces of backhaul disc main body tilt.
Further, the tilt angle on the inclined-plane of the backhaul disc main body is 45 °.
Utility model has the advantages that in the present invention, for the end face of backhaul disc main body, by using two sides
Be the mode on inclined-plane so that return plate is when being swung, the end of return plate will not contact in advance inclined plate or
Cylinder ends, the hunting range for allowing for return plate in this way is bigger, to increase the stroke range of plunger.
45 ° are both designed as the tilt angle on inclined-plane, so that the increased hunting range of backhaul side surface both sides institute is similar,
To the synchronous stroke range for increasing plunger release piston shoes or the stroke range for retracting piston shoes.
Detailed description of the invention
Utility model will be further described in detail below with reference to the attached drawings and specific embodiments.
Fig. 1 is the schematic diagram of the plunger pump modified return plate of the utility model.
Specific embodiment
The following examples can make professional and technical personnel that the utility model be more fully understood, but therefore will not
The utility model is limited among the embodiment described range.
A kind of plunger pump modified return plate as shown in Figure 1, including
One backhaul disc main body 1, the backhaul disc main body 1 are a disc-shaped structure, are had in the medium position of backhaul disc main body 1
The through-hole that one appearance transmission shaft 2 passes through is located at around through-hole 2 on backhaul disc main body 1 and is also equipped with several distributions of shape in a ring
Hold piston shoes installation mounting hole 3.
The two sides of the circumferential end surfaces of backhaul disc main body 1 are inclined-plane 4, and the inclined direction on inclined-plane 4 is from backhaul disc main body 1
Center to backhaul disc main body 1 end direction gradually to the centerline direction of the circumferential end surfaces of backhaul disc main body 1 tilt.For
The end face of backhaul disc main body 1 is the mode on inclined-plane 4 by using two sides, so that return plate is when being swung,
The end of return plate will not contact inclined plate or cylinder ends in advance, and the hunting range for allowing for return plate in this way is bigger, to increase
The stroke range of plunger is added.
The tilt angle on the inclined-plane 4 of backhaul disc main body 1 is 45 °.45 ° are both designed as the tilt angle on inclined-plane 4, is made
It is similar to obtain the increased hunting range of backhaul side surface both sides institute, so that the synchronous plunger that increases is released the stroke range of piston shoes or retracted
The stroke range of piston shoes.
It should be understood by those skilled in the art that the present utility model is not limited to the above embodiments, above-described embodiment and
Only illustrate the principles of the present invention described in specification, on the premise of not departing from the spirit and scope of the utility model,
The utility model also has various changes and improvements, these changes and improvements both fall within the scope of the claimed invention
It is interior.The protection scope of the present invention is defined by the appended claims and their equivalents.
