(1) technical field
The utility model relates to a kind of suction booster, particularly a kind of hydraulic drive liquid booster pump.
(2) background technique
At present, a lot of places need supercharging, and the reversing mode of supercharging now mainly contains three kinds: the one, and pressurized machine adds electric element opsition dependent and comes the controlled motion direction; The 2nd, control commutation with pressure relay; The 3rd, drive mechanical commutation mechanism with pressurized machine and commutate.
Pressurized machine adds electric element opsition dependent control and uses many, the position that limits the pressurized machine two ends near switch or other induction switches is housed respectively with pressurized machine pressurizing piston or driven plunger two ends, add that electric controling element controls pressurized machine commutation, realize supercharging.
Pressurized machine plus-pressure relay pressing force is controlled commutation, and hydraulic pressure rising in another cavity when promptly driven plunger moves to an end is when pressure reaches the pressure relay setting pressure, the commutation of electrical control pressurized machine, charged piston moves to opposite side, and so forth, realizes supercharging.
More than two kinds of control modes, be electrical control, control loaded down with trivial detailsly, the fault point is many, the reliable operation degree is not too high, is not suitable for the flame proof occasion.Pressurized machine drives mechanical commutation mechanism, commutates when making pressurized machine arrive dead-centre position, reaches the reciprocating effect of driven plunger, realizes supercharging.Mechanical mechanism commutating structure complexity is made trouble, and is bulky.
(3) summary of the invention
The utility model is in order to remedy the deficiencies in the prior art, and a kind of hydraulic drive liquid booster pump of simple in structure, reliable operation is provided.
The utility model is achieved by the following technical solution:
A kind of hydraulic drive liquid booster pump, comprise mainly by driving the driving oil hydraulic cylinder that cylinder barrel, driven plunger and driving cylinder cap are formed, it is characterized in that: the driven plunger both sides are provided with and pass the piston rod that drives cylinder cap, piston-rod end is fixed with the charged piston that is positioned at the supercharging cylinder barrel, supercharging cylinder barrel end is provided with inlet one-way valve and outlet one-way valve, drives oil hydraulic cylinder and is provided with the commutation control section.
Driving oil hydraulic cylinder of the present utility model connects pressurized cylinder by piston rod, and when the driven plunger to-and-fro motion, drives charged piston and move reciprocatingly, and the fluid in the supercharging cylinder barrel is pressurizeed; Utilize the special construction on driven plunger and the driving cylinder barrel, for selector valve provides control oil, make selector valve automatic reverse, hydraulic oil is controlled, driven plunger is moved reciprocatingly automatically, realize that the supercharging of suction booster is moved by the commutation control section.
More excellent scheme of the present utility model is:
Described commutation control section comprises that being communicated with the commutation that drives oil hydraulic cylinder controls integrated package, hydraulicchange-over valve and hydraulic control part; Described hydraulicchange-over valve is two four-way hydraulicchange-over valves, is communicated with filler opening, drive cylinder tube inner chamber, hydraulic control part and return opening respectively.
The drive cylinder of described driven plunger, charged piston and socket piston rod covers and is provided with Sealing.
The utility model compared with prior art has the following advantages:
(1) no electrical control.Thoroughly eliminated the fault of loaded down with trivial details circuit and electric elements (near switch, relay, PLC etc.); Adopt position of piston to cut off and connect the position that control oil is controlled selector valve, determine the moving direction of piston, realize to-and-fro motion; Whole control process, medium tache is few, and is simple in structure, and control unit is few, and rate of fault is low, and it is more reliable to work; No electric elements does not have electrical spark and produces, so can be used for the flame proof occasion.
(2) has more intense flexibility.Owing to adopt the mode of hydraulic control commutation; Reduce the loaded down with trivial details structure of mechanical part, made simple in structurely, reduced the leakage hidden danger that mechanical export structure brings.Also can make cylinder part and commutation control section separate design, can be more suitable for special installation requirement.
(3) has adaptability widely.Can be by the piston area ratio of change design driven cylinder with pressurized cylinder, convertible multiple pressure ratio has reached required pressure and traffic requirement; Also can adapt to the more medium that needs supercharging by the material that changes pressurization cylinder barrel, pressurization end cap, pressurizing piston and Sealing.
The utility model does not have electrical control, and mechanism is simple, reliable operation, and no electrical spark is fit to the flame proof occasion, is particluarly suitable for working under the situation of high-power, particular surroundings, special media.
