Abstract
The utility model relates to a hydraulic driven metering pump. The utility model is composed of a dynamic power part, a hydraulic transmission part and a pump body part. A pump body is a honeycomb-shaped body which is connected with a piston cylinder, four plunger pumps, a liquid inlet pipe and a liquid drainage pipe through two connecting plates. The interior of the connecting plate is provided with an annular passage, a piston and a piston rod which are connected by an interlocking rod. The utility model can be used for electric power, chemical engineering, urban water supply and drainage, etc. The utility model has no box body. The utility model has the advantages of small volume, large flow capacity, reasonable structure and high stress strength.
Description
The utility model belongs to a kind of fluid conveying machine field---hydraulic driving metering pump.
At present general mechanical metering pump since force bearing point concentrate, so quick abrasion, vibration frequency height, deficiency such as the little instability of flow, volume are big.
The purpose of this utility model is in order to obtain long service life, high pressure, stable big flow, and the little power saving of volume and design a kind of by the moving novel metering pump of hydraulic pressure body.
This metering pump is to realize with following technical proposal: it comprises: power, hydraulic pressure transmission and pump housing three parts, its middle pump body is by piston cylinder, four plunger pumps, liquid inlet pipe, liquid-discharging tubes they to be connected its two ends respectively by two joining plates to be cellular type body, in each joining plate, be provided with the annular pass, and be connected with the bottom surface of two plunger pumps respectively, also communicate with liquid inlet pipe and liquid-discharging tube respectively by two one-way valves.End face at each joining plate is respectively equipped with linkage rod, by it two plungers in plunger pump is connected with piston rod.
The utility model does not have casing, and is rational in infrastructure, is subjected to the force intensity height, and it is by the variation of piston area with the sectional area of plunger ratio, can obtain desirable high pressure and flow, and piston two-way work has two plunger pumps all the time at drain, so flow is big.The no idle running of hydraulic pressure transmission, the energy utilization is abundant, power saving.
Description of drawings of the present utility model:
Fig. 1 is the appearance structure schematic representation of the pump housing.
Fig. 2 is the sectional drawing of joining plate.
Fig. 3 is the utility model bulk shape connection diagram.
Fig. 4 is the utility model workflow schematic representation.
1～4 pair of overall structure of the present utility model and workflow thereof are described in further detail in conjunction with the accompanying drawings:
Shown in Fig. 1～3: this hydraulic driving metering pump by motor 13 as power; Control panel 7, Flow valve 8, selector valve 9, oil pump 10 and oil pipe 16 have constituted the hydraulic pressure hop; By piston cylinder 2, four plunger pumps 3, liquid inlet pipes 4, liquid-discharging tube 5 connects them respectively by two joining plates 1 with its two ends become cellular pump housing part, linkage rod 15 connects together two plungers and piston rod.Be provided with an annular pass 18 in each joining plate, the bottom surface with two plunger pumps is connected respectively, and communicates with liquid inlet pipe 4, liquid-discharging tube 5 respectively by two one-way valves 6.Wherein Flow valve 8, selector valve 9 are connected on the survey end of pump housing joining plate by control panel 7.The whole pump housing is fixed on the fuel tank 11 by mounting angle plate 14.
Its workflow is: shown in Figure 4ly drive oil pumps 10 by motor 13 pressure oil is sent into Flow valve 8 by oil pipe 16, reconcile and reach required flow, enter oil cylinder 2 (a piston left side) by selector valve 9, and the oil on the piston right side flows back to fuel tank 11 by selector valve 9.When piston is pushed into from left to right, drive linkage rod 15, the plunger that drives simultaneously in the plunger pump 3 moves from left to right, and two plunger outward discharge opeings that continuous motion stem drove on the piston left side at this moment make liquid go out one-way valve 6 by annular pass 18 and enter liquid-discharging tube 5 and deliver to feed flow place 17 at last.Simultaneously other two plunger outward that linkage rod drove on piston the right are pulled out formation suction, make its with liquid from flow container 12 sucking-offs through liquid inlet pipe 4, break through one-way valve 6 and enter annular pass 18 and suck in the plunger pumps 3.When selector valve 9 is hit in piston motion during to right-hand member, commutation pressure oil makes piston to left movement to piston the right voltage supply, and two plunger pumps that drive the right drive that linkage rod connects are to exterior liquid, and other two plunger pumps are in imbibition.Circular flow constantly has liquid to discharge all the time like this, and reaching oil pump does not have idle running, the purpose that flow is big.
