Abstract
The invention relates to a guiding type pressurization sleeve of a hydraulic pump oil tank. The guiding type pressurization sleeve of the hydraulic pump oil tank comprises a pressurization sleeve body. The pressurization sleeve body comprises an upper pipe body and a lower pipe body. The upper pipe body is provided with a conical through hole. The lower pipe body is provided with a cylindrical hole communicating with the conical through hole. The inner wall of the conical through hole is provided with a plurality of pressurization grooves which are symmetrically arranged relative to the center of the conical through hole. The pressurization grooves penetrate the conical through hole from the upper end to the lower end. The pressurization grooves are provided with curve-shaped structures, and the upper end and the lower end of each pressurization groove are obliquely arranged relative to the end faces of the pressurization sleeve body. A plurality of guiding grooves which are approximately of L structures are further formed in the side wall of the pressurization sleeve body. The upper end of each guiding groove communicates with the upper end face of the pressurization sleeve body, and the lower end of each guiding groove communicates with the conical through hole. The guiding type pressurization sleeve of the hydraulic pump oil tank is simple in structure; by arranging the pressurization sleeve on a piston rod of the oil tank, return oil can be guided into the oil tank easily, the piston pushing force is improved, and accordingly the pressurization effect is improved; by arranging the curve-shaped pressurization grooves and the guiding grooves, the pressurization effect is improved, and the pressurization guide resistance is reduced.
Description
Technical field:
The present invention relates to field of hydraulic equipment, particularly to the fuel tank of hydraulic system.
Background technology:
In hydraulic system, fuel tank is mainly used to the air in oil storage, heat radiation and separating medium force feed, impurity etc. The quality of tank design directly influences the functional reliability of Hydraulic Elements and system, and there is conclusive impact in the life-span particularly with hydraulic pump. Under or environment that air pressure is less higher for height above sea level, according to general open type oil tank, often lead to the reduction of hydraulic pump inlet pressure and cause the cavitation erosion of hydraulic pump, have a strong impact on the normal operation of hydraulic system, it is thus desirable to adopt the flow-guiding type booster set of hydraulic pump fuel tank, the flow-guiding type booster set of hydraulic pump fuel tank can increase the pressure on tank-level, it is prevented that hydraulic pump produces cavitation erosion, thus being effectively improved the high-level performance of hydraulic system. The shortcoming of the flow-guiding type booster set of traditional hydraulic pump fuel tank is that pressurized effect is not good, fuel tank go out that oil pressure is relatively low, oil yield efficiency is low.
Summary of the invention:
The applicant, for the disadvantages mentioned above of tradition fuel tank, carries out studying and improving, it is provided that the flow-guiding type booster set of a kind of hydraulic pump fuel tank, and it has simple in construction, pressurized effect is good, manufacture feature easy to process, that cost is low.
In order to solve the problems referred to above, the present invention adopts following scheme:
A kind of flow-guiding type booster set of hydraulic pump fuel tank, including booster set body, described booster set body includes upper tube body and lower tube body, upper tube body is with conical through-hole, lower tube body is with the cylindrical hole connected with conical through-hole, the inwall of described conical through-hole is with multiple supercharging grooves that its center is arranged symmetrically with relatively, and supercharging groove runs through the upper and lower side of described conical through-hole; Described supercharging groove is with curve-like structure, and the end slope of its upper and lower side relative booster set body respectively is arranged; The sidewall of described booster set body is additionally provided with the guiding gutter of multiple class L-type structure, and the upper end of guiding gutter is through with the upper surface of booster set body, and its lower end connects with conical through-hole.
The method have technical effect that:
The simple in construction of the present invention, is installed on the piston rod of fuel tank, is beneficial to and oil return is imported, and improves the motive force to piston, thus improving pressurized effect to arrange curvilinear supercharging groove and guide trough structure, improving pressurized effect, reducing supercharging baffling resistance.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention:
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further.
As shown in Figure 1, the flow-guiding type booster set of the hydraulic pump fuel tank of the present embodiment, including booster set body, booster set body includes upper tube body 1 and lower tube body 2, upper tube body 1 is with conical through-hole 11, lower tube body 2 is with the cylindrical hole 21 connected with conical through-hole 11, and the inwall of conical through-hole 11 is with multiple supercharging grooves 12 that its center is arranged symmetrically with relatively, and supercharging groove 12 runs through the upper and lower side of conical through-hole 11; Supercharging groove 12 is with curve-like structure, and the end slope of its upper and lower side relative booster set body 1 respectively is arranged; The sidewall of booster set body 1 is additionally provided with the guiding gutter 13 of multiple class L-type structure, and the upper end of guiding gutter 13 is through with the upper surface of booster set body 1, and its lower end connects with conical through-hole 11.
The simple in construction of the present invention, is installed on the piston rod of fuel tank, is beneficial to and oil return is imported, and improves the motive force to piston, thus improving pressurized effect to arrange curvilinear supercharging groove and guide trough structure, improving pressurized effect, reducing supercharging baffling resistance.
