Abstract

The invention discloses a confluence block used for filling an industrial pump hydraulic pressure return line, an oil inlet and an oil return port which are communicated mutually are arranged on the confluence block, the oil inlet is connected with the hydraulic system oil return pipe, the oil return port is communicated with an oil tank; an accumulator communicated with the oil inlet and the oil return port is arranged on the confluence block main body, and the accumulator is capable of absorbing pulse impact effectively so as to protect hydraulic elements such as oil return filter and heat radiator from damage under moment oversize oil return impact force; and the check valve arranged on the confluence block is communicated with the main return line, and when an oil return pressure is oversized, a majority of hydraulic oil reflows to the oil tank through the main return line, thereby avoiding the heat radiator from being damaged due to an oversized pressure. In the invention, the connection of an industrial pump hydraulic pressure return oil system hose is simplified so that the ducting connection is more convenient and damage to a hydraulic pressure return line element is diminished effectively, the parallel arrangement of the main return line and oil return branches is beneficial to realizing such automatic regulation that filtration is chosen as a primary operation when the oil temperature is low and the heat dissipation is chosen as a primary operation when the oil temperature is high.

Description

Filling industrial pump hydraulic oil-returning piece that confluxes for pipeline
Technical field
The invention belongs to hydraulic component, be specifically related to the filling industrial pump hydraulic oil-returning piece that confluxes for pipeline.
Background technique
The rated flow of filling industrial pump hydraulic system when work and pressure are all higher, and (flow reaches 2000L/min, system pressure 31MPa), return line and device thereof itself have certain return oil pressure, the impact of pulsatile impact and main reversing valve commutation during due to hydraulic work system, cause the suffered pulsatile impact of the hydralic hose of return line very large, the pressure variation of moment easily causes damage to the hydraulic pressure components and parts on return line, particularly when return pressure is excessive, radiator on main return line will be impacted, radiator is the main cooling element of high-temperature liquid force feed in hydraulic system pipeline, as being damaged, radiator will have influence on the normal operation of whole hydraulic system.
Due to the high pressure of filling industry pump hydraulic system, large flow, so the oil return sebific duct latus rectum that return line is selected is larger, hydralic hose is easily damaged parts, there is certain working life, need running check to change, oil return sebific duct very slightly and longer, is subject to spatial constraints to be difficult for stringing and is difficult to fix under oil return pulsatile impact power during assembling, produce each other strong interference and noise, seriously shorten the sebific duct life-span.
Summary of the invention
The invention provides the filling industrial pump hydraulic oil-returning piece that confluxes for pipeline, while being used for solving existing return line pressure variation, the easy damage of hydraulic pressure components and parts and hydralic hose are difficult for the shortcomings such as installation, can also realize oil temperature when low to be filtered into master, take when oil temperature is high heat radiation is that main automatic flow regulates.
The present invention adopts following technological scheme: filling industrial pump hydraulic oil-returning piece that confluxes for pipeline, described in conflux in piece main body and offer filler opening and return opening, in the described piece body interior of confluxing, offer the asphalt channel being communicated with described filler opening and return opening; Described filler opening connecting fluid pressing system oil returning tube, described return opening is communicated with fuel tank; In the described piece main body of confluxing, be also provided with and the filler opening of the piece that confluxes, the accumulator that return opening is communicated with.
In the described piece main body of confluxing, be at least provided with two return openings, the first return opening is communicated with fuel tank by main return line, on described main return line, is provided with one-way valve and return filter; The second return opening is communicated with fuel tank by oil return branch road, on described oil return branch road, is provided with radiator.
Described one-way valve is bolted to be arranged at and confluxes in piece main body, and one end is connected with the first return opening, and the other end is connected with return filter, and return filter is communicated with fuel tank.
In the described piece main body of confluxing, be also provided with and the filler opening of the piece that confluxes, the pressure measuring tie-in that return opening is communicated with.
Described filler opening, the return opening confluxing in piece main body is provided with the split flange folder for connected pipes.
The present invention adopts the piece that confluxes that hydraulic system return line is pooled together, and then unified backflow fuel tank, has avoided the too much long Large Diameter Pipeline sebific duct of employing in loop; The accumulator and the one-way valve that in the piece main body of confluxing, arrange.When return line pressure is normal, hydraulic oil flows into by filler opening the piece that confluxes, the hydraulic oil of a part carries out flowing back to fuel tank radiating and cooling to hydraulic oil by radiator from the second return opening, and a part of hydraulic oil can flow back to fuel tank by the first return opening after one-way valve and return filter filtration.When oil-return pipeline system pressure instantaneous variation, accumulator impact-absorbing pressure peak, protection return filter, radiator be not to be subject to moment excessive oil return impact force damaged.When oil temperature is lower, most hydraulic oil can flow back to fuel tank through one-way valve and return filter by the first return opening, effectively avoids radiator to damage because Low Temperature Liquid resistance increases.This first, second oil return be arranged in parallel realize oil temperature when low to be filtered into master, take when oil temperature is high heat radiation is that main automatic flow regulates.In the piece main body of confluxing, be also connected with pressure measuring tie-in, the pressure of the return line of cut-in pressure table monitoring at any time.
In sum, the present invention is by filler opening and the return opening connection rubber tube of the piece main body of confluxing, more reasonable stringing, and hydraulic fluid port is concentrated, and has effectively shortened sebific duct length, the stringing of sebific duct and dismantle, convenient maintenance and replacement are installed.The one-way valve arranging in the piece main body of confluxing and accumulator can effectively be protected return filter, the radiator in return line, and the present invention is simple in structure, connecting pipeline is convenient, can effectively protect hydraulic oil-returning pipeline parts not damaged.
