Abstract
The utility model is characterized in that two sets of automatically transmitting mechanisms and an integral type converting valve group controlled by an automatic signal are arranged at the corresponding position of a supercharging cylinder; no exposed element is arranged in the signal generating and transmission system. Thus, the usually adopted cockamamie mechanisms, such as machinery, electricity, etc. are cancelled. The utility model has the advantages of simple device, strong adaptability, reliable starting and operation, and good dust proofing and sealing; if the pressure oil is side entered to the supercharger of the utility model once, two continuous high voltage output can be obtained. The eversing arrangement for a supercharger can be used in the series products of the double-acting intensifier of different dimensions and different pressure ratio, and an ultra-high pressure automatic supercharger is also included.
Description
The utility model belongs to hydraulic transmission technology.
The reversing arrangement of general double-acting supercharger has: machine---electric control, machine---machine or machine---hydraulic control system and liquid---hydraulic control system three major types.Modal is first class.It is to be met and discussed by moving elements such as piston bump machinery, by position limit switch, relay, makes the solenoid valve commutation.Its shortcoming is that system's link is more, and device is complicated, and sealing and reliability are relatively poor, easily produce hydraulic shock, and second type is by the machinery manipulation machine liquid changing valve of meeting and discussing, and hydraulic operated valve is commutated; Or utilize and to be contained in the stroke that And Shang the Huo Sai stretches out the casing wall of cutting open the belly and to meet and discuss, stir the commutation of stroke valve.Its shortcoming is a complex structure, size is big, and machine---machine control mode not only size is big, and sealing, anti-dust performance are poor, and efficient is low, the 3rd type is normally utilized piston, casing wall annular groove and duct sender, make the hydraulic operated valve commutation, its shortcoming is because the annular groove spacing is restricted, can not be too big, simultaneously, annular groove causes the destruction of piston seal easily, makes sealing reduce job insecurity, efficient is lower, moreover, its effective travel and low pressure (LP) cylinder length ratio, effective travel compares M, always be less than 1/2nd, so physical dimension is big.
The present invention seeks to overcome above-mentioned shortcoming, provide that a kind of simple and compact for structure, dustproof, sealing is good, starting, reliable, use, easy to maintenance, adaptability is strong, efficient is high automatic hydraulic reversing arrangement.
Solution of the present invention is a (see figure 1): the sender mechanism design is in intensifier body, it forms the b of another sender mechanism, (3), (4) and preceding group of symmetrical distribution by two apertures (1), (2) on annular groove a on the booster rod (10) and pressurized cylinder (11) the casing wall sealing position.Integrated type selector valve group mainly is made up of the throttle valve (5) (6) that valve body (9), guide's guiding valve (7), main commutation are surged on guiding valve (8) and two valve gaps.Board-like connection is installed on the pressurized machine cylinder body.When piston to left movement, when aperture (1), (2) are connected through a, deliver to aperture (2) through aperture (1), annular groove a from the control oil of low pressure oil circuit L, obtain a pilot signal.This signal enters the left end of guide's guiding valve (7), spool is shifted onto right end position, hydraulic fluid port P, B and A, O connect respectively, the fluid of right-hand member flows back to oil sump Q through valve (6), at this moment deliver to the surge left end of guiding valve (8) of main commutation from L through the secondary of hydraulic fluid port P, the B of guide's guiding valve (7) control oil, this spool is pushed to right end position, its hydraulic fluid port P, B connects, the fluid of right-hand member arrives guide's guiding valve (7) hydraulic fluid port A through valve body (9) runner, cross valve core channel to hydraulic fluid port O, return oil sump Q by the road, thereby realize the commutation of first side oil circuit.Low pressure oil enters chamber, a piston left side by L through surge hydraulic fluid port P, the B of guiding valve (8) of main commutation; Right chamber fluid is got back to oil sump Q through surge A, the O hydraulic fluid port of guiding valve (8) of main commutation, and piston begins to move right.When moving to the b groove with aperture (3), when (4) are connected, obtain a commutation signal simultaneously, be directed at the commutation of first side oil circuit again, piston restarts stroke left, so goes round and begins again, and just obtains continuous secondary high-pressure output at pressurized machine oil outlet H.If the second side high-pressure medium is different with first side, then the pipeline before the two pressurized cylinder import one-way valves can be cut off from shown position, receive after the merging in the medium of high pressure side and go.
The present invention and existing similar control pattern compare, and sender mechanism has simple in structure, and working stability is reliable, advantages such as good airproof performance.Adopt the pressurized machine effective travel of this device bigger than the M value, compact structure, working service are conveniently, high pressure is steady, efficient is high.As long as at first side pushing inlet pressure oil, this reversing arrangement under any circumstance can both start pressurized machine reliably, devotes oneself to work, and obtains continuous secondary high-pressure output.
In some mechanical design of Hydraulic System, rationally adopt pressurized machine, will make system works reliable more economically, only single pump work with this reversing arrangement, can obtain low pressure and mass flow and high-pressure low-flow fuel feeding, according to the variation of load, can realize the automatic conversion of pressure height and speed speed, the corresponding simplification of electrical system, pump and part valve class component can be selected the lower pressure grade for use, the hydraulic station volume reduces, and cost reduces, obvious energy conservation.
Embodiment of the present invention can at first, with selector valve group part reference orientation valve class series product, be pressed different pressures level and latus rectum specification in conjunction with the relevant explanation in front, make standardization such as its guiding valve, installation dimension, form respective series.According to the requirement of pressurized machine, select corresponding specification for use; In cylinder body design, satisfy its installation requirement, the selector valve group is as individual components, convenient for maintaining and emergency replacement.Then, with two groups of sender mechanisms, promptly annular groove and signal aperture are produced on the pressurized machine specified parts, guide to valve group attachment face connecting the duct.The present invention is applicable to the various double-acting supercharger series product of different capabilities, different pressure ratio and cylinder diameter, comprises the ultrahigh pressure self booster.
