Embodiment
Below in conjunction with the drawings and specific embodiments, hydraulic pressure gas vacuum of the present invention is described further, in accompanying drawing, parts same as the prior art have adopted identical label.Following each embodiment is not only limitation of the present invention for the present invention is described.
Fig. 1 is the structural representation of hydraulic pressure gas vacuum of the present invention.As shown in Figure 1, hydraulic pressure gas vacuum of the present invention, comprise the middle oil cylinder part 1 that drives hydraulic oil, is connected to left compression cylinder part 2 and the right compression cylinder part 3 at oil cylinder part 1 two ends.
Oil cylinder part 1 comprises cylinder tube 4 and is arranged on the oil cylinder piston 5 in cylinder tube 4.Hydraulic jack part 1 adopts the hydraulic control mode, by the control that commutates of hydraulic control reciprocating device, thereby reaches the to-and-fro motion of hydraulic jack.
Left compression cylinder part 2 comprises the left compression cylinder piston 7 of left compression cylinder cylinder barrel 6 and left compression cylinder cylinder barrel 6 interior settings.Left compression cylinder cylinder barrel 6 two ends are provided with Aspirating valves and outlet valve, and left end is the first Aspirating valves 8 and first row air valve 9, and right-hand member is the second Aspirating valves 10 and second row air valve 11.
Right compression cylinder partly comprises the right compression cylinder piston 13 of right compression cylinder cylinder barrel 12 and right compression cylinder cylinder barrel 12 interior settings, right compression cylinder cylinder barrel 12 two ends are provided with Aspirating valves and outlet valve, left end is the 3rd Aspirating valves 14 and the 3rd outlet valve 15, and right-hand member is the 4th Aspirating valves 16 and the 4th outlet valve 17.
Left compression cylinder piston 7, oil cylinder piston 5 and right compression cylinder piston 13 are connected on same piston rod.
The pressure signal of described liquid controlled reversing is directly to obtain from the two ends of oil cylinder part.
Cooling jacket is equipped with in the outside of described left compression cylinder cylinder barrel 6 and right compression cylinder cylinder barrel 12, takes the water-cooling pattern cooling.
Left compression cylinder cylinder barrel 6 and right compression cylinder cylinder barrel 12 are cylindric, very easily realize the stepless variable of hydraulic pressure gas compression pump, and the difference of satisfying the market needs.
All be socketed nonmetal seal ring, good sealing effect, and durable on left compression cylinder piston 7, oil cylinder piston 5 and right compression cylinder piston 13.
During use, this hydraulic pressure gas vacuum needs a hydraulic-pressure pump to be used in conjunction with.Prime mover supporting with hydraulic-pressure pump both can adopt motor also can adopt internal-combustion engine, by changing the hydraulic oil pump delivery, just can meet the large-scale Flow-rate adjustment requirement of hydraulic pressure gas vacuum.
The working procedure of hydraulic pressure gas vacuum of the present invention is as follows:
At first, to oil cylinder part 1, by hydraulic pressure automatic reverse technology, make oil cylinder piston 5 automatic reciprocating motions by the hydraulic-pressure pump fuel feeding.The piston rod two ends of hydraulic jack directly are connected with the compression cylinder piston, in the compression cylinder cylinder barrel, do straight reciprocating motion.When oil cylinder piston 5 moves to left end, three pistons are moved to the left simultaneously.Gas in left compression cylinder cylinder barrel 6 is squeezed, and pressure raises, thereby the first Aspirating valves 8 cuts out, first row air valve 9 is squeezed to be opened, liquid or gas are released by left compression cylinder piston 7, via first row air valve 9, enter discharge tube, and this working procedure is the discharge process of vacuum pump.In this process, the second Aspirating valves 10 is in open mode, and second row air valve 11 is in closed condition.In right compression cylinder cylinder barrel 12, the movement of right compression cylinder piston 13 makes in cylinder to form negative pressure, and like this, outside gas enters in cylinder by the 4th Aspirating valves 16, and the 4th outlet valve 17 is closed, until piston moves on to leftmost position.This working procedure, the i.e. suction process of pump.In this process, the 3rd Aspirating valves 14 is in closed condition, and the 3rd outlet valve 15 is in open mode.When piston moves on to leftmost bit postpone, the automatic reverse piston starts to move right.
The present invention adopts the direct driven plunger moving linearly of hydraulic jack, and simple in structure, part is few, volume is little, lightweight, raises the efficiency.With traditional mechanical transmission triplex pump contrast, hydraulic pressure gas compression pump number of spare parts has reduced 65%, and volume and weight has reduced more than 60%.Compared with the crankshaft-link rod speed-changing gear box, come, power end can be accomplished long stroke, low jig frequency, thereby the life-span is long, fault is few, maintenance expenses is low.Be five to ten times of common mechanical reciprocating pump the working life of compression cylinder piston, cylinder barrel, valve body, valve seat and piston rod lamp part.
Hydraulic pressure gas vacuum of the present invention can unit work, again can multi-machine parallel connection work, in many use occasions that require high-power (high-pressure high-flow), the hydraulic pressure gas vacuum of multi-machine parallel connection work not only can greatly reduce manufacture cost, more rare is to carry out seamless coupling with the requirement of these occasions, and this is that mechanical reciprocating piston air pump is difficult to accomplish.
