Abstract
The utility model relates to a plunger pump part, in particular to a low-noise oil pumping mechanism for hydraulic plunger pumps, which belongs to the technical field of plunger pumps. The low-noise oil pumping mechanism comprises a housing, the interior of the housing is provided with a round oil push cavity, a rotor is eccentrically arranged in the oil push cavity, the rotor is provided with a plurality of positioning cavities evenly arranged along the circumferential direction, a seal pin is mounted in each positioning cavity, and the upper ends of the seal pins are in tight contact with the sidewalls of the oil push cavities. Both ends of the housing are respectively provided with an oil outlet and an oil inlet, the oil outlet is provided with an oil outlet passage which is communicated with the oil push cavity, and the oil inlet is provided with an oil inlet passage which is communicated with the oil push cavity. The structure of the low-noise oil pumping mechanism is simple, compact and reasonable; because the combination of the seal pins and springs is adopted, the seal pins can constantly keep tight connection with the housing, consequently, the sealing property of the low-noise oil pumping mechanism for hydraulic plunger pumps is effectively enhanced, and moreover, working noise is effectively reduced; the low-noise oil pumping mechanism is worth popularizing and using.
Description
Technical field
The utility model relates to a kind of plunger pump parts, and a kind of low-noise pumping unit structure for hydraulic planger pump, belongs to plunger pump technique field specifically.
Background technique
Hydraulic piston pump is to drive hydraulic jack by hydraulic power bag, and hydraulic jack advances carries cylinder, will carry the material in cylinder to export pipeline to.Hydraulic piston pump is generally divided into single plunger pump and double plunger pump, is specially adapted to high solid content, the long-distance transportation through pipeline of sticky material, and its advantage is that operation is highly stable, reliable.Be widely used in sewage treatment, Solid Waste Treatment, mine is metallurgical, desilting, dredging, petrochemical industry, power plant, the fields such as cement industry.But the oil pumping mechanism noise of hydraulic planger pump of the prior art is larger, and sealing is inadequate, so pressure just not, is unfavorable for applying, and need to improve.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, thereby a kind of low-noise pumping unit structure for hydraulic planger pump is provided, and effectively raises the sealability of hydraulic planger pump oil pumping mechanism, and effectively reduces operating noise.
The technological scheme providing according to the utility model, low-noise pumping unit structure for hydraulic planger pump comprises housing, in housing, be provided with the circular oil pocket that pushes away, it is characterized in that: push away eccentric setting rotor in oil pocket, rotor is along the circumferential direction evenly provided with a plurality of positioning chambers, a link block is installed, link block upper end and push away oil pocket sidewall close contact in each positioning chamber; Housing two ends are respectively equipped with oil outlet and filler opening, be provided with and be communicated with the oil discharge passage that pushes away oil pocket in oil outlet, be provided with and be communicated with the oil inlet passage that pushes away oil pocket in filler opening.
Further, between positioning chamber bottom and link block, be provided with spring.
Further, positioning chamber is six.
Further, push away between oil pocket and filler opening and be provided with branching block, in branching block, be provided with three split channels, three split channels all with push away oil pocket and oil inlet passage is communicated with.
Compared with the prior art the utility model has the following advantages:
The utility model is simple in structure, compact, reasonable, adopt the combination of a plurality of link blocks and spring, make link block constantly keep being connected with the close of housing, thereby effectively raise the sealability of hydraulic planger pump oil pumping mechanism, and effectively reduce operating noise, there is the value of promoting and using.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Description of reference numerals: 1-oil outlet, 2-housing, 3-filler opening, 4-push away oil pocket, 5-rotor, 6-positioning chamber, 7-link block, 8-spring, 9-oil discharge passage, 10-oil inlet passage, 11-branching block, 12-split channel.
Embodiment
The utility model is further described in connection with the embodiment in accompanying drawing below:
As shown in Figure 1, the utility model mainly comprises housing 2, is provided with the circular oil pocket 4 that pushes away in housing 2, pushes away eccentric setting rotor 5 in oil pocket 4.
Described rotor 5 is along the circumferential direction evenly provided with a plurality of positioning chambers 6, and a link block 7 is installed in each positioning chamber 6, link block 7 upper ends and push away oil pocket 4 sidewall close contacts.In embodiment as shown in Figure 1, positioning chamber 6 is six.
Between described positioning chamber 6 bottoms and link block 7, be provided with spring 8.
Housing 2 two ends are respectively equipped with oil outlet 1 and filler opening 3, be provided with and be communicated with the oil discharge passage 9 that pushes away oil pocket 4 in oil outlet 1, be provided with and be communicated with the oil inlet passage 10 that pushes away oil pocket 4 in filler opening 3.
Push away between oil pocket 4 and filler opening 3 and be provided with branching block 11, in branching block 11, be provided with 12, three split channels 12 of three split channels all with push away oil pocket 4 and oil inlet passage 10 is communicated with.
The utility model adopts the combination of a plurality of link blocks and spring, make link block constantly keep being connected with the close of housing, thereby effectively raise the sealability of hydraulic planger pump oil pumping mechanism, and effectively reduce operating noise, there is the value of promoting and using.
