Abstract
The utility model discloses a labor-saving piston hydraulic pump with a lever rock arm as power, comprising a plurality of bearings disjunctively arranged on a crank shaft in a pump body, and a plurality of linkage shafts respectively equipped with linkages. The other end of the lever rock arm connected with the linkage is connected with the upper and the lower piston pumps by a positioning pin and a connecting rod respectively; separation channels are arranged outside a copper sleeve in the piston pump, and a standing valve and a delivery valve are arranged inside the pump. The utility model is labor and energy saving. The model is of the same machine with prior pressure hydraulic pump by tests, and the model is characterized in that the utility model can save more than 30% fuel and will be widely used in the future. And the model is used preferred in construction machinery the as excavator and the like and ship power. The utility model is simple constructed, safe and reliable, low in cost, relatively convenient when implementing and easy when operating.
Description
Technical field
The utility model relates to a kind of multistage hydraulic pump, especially a kind of lever rocking arm power energy saving plunger hydraulic pump.
Background technique
So far, oil hydraulic pump hydraulic unit constructed products is more and more both at home and abroad, and hundreds of oil hydraulic pumps are often arranged on the market, and it is not the pressure oil hydraulic pump that considerable part is wherein arranged.The oil hydraulic pump of excavator is the pressure oil hydraulic pump, and common oil hydraulic pump is axle band tapered plane rotating hydraulic plunger pump and gear pump.Its oil temperature that hydraulic pressure in use habitually in the past occurs is too high, causes oil hydraulic pump pressure not reach job requirement, even motor often occurs loading excessive in the course of the work.Because tapered plane pressure and excavator working arm device do not wait, working arm is the effort lever entirely, so operation power is excessive under the situation of existing design, causes the fuel oil oil consumption big especially, and cost of production is too high.In addition, when the maintenance fluid press pump, also exist related accessory price height and accessory and original part to be difficult to equal mutually problem.
Summary of the invention
The purpose of this utility model provide a kind of simple in structure, cost is low, efficient height, easy to operate, fuel-efficient lever rocking arm power energy saving plunger hydraulic pump.
Technical solution adopted in the utility model is: the utilization lever principle, separate on the bent axle of establishing in the pump housing a plurality of bearings and many pitman shafts that connecting rod is housed respectively are installed, the lever rocking lever the other end that is connected with connecting rod connects two plunger pumps up and down respectively by locating stud, connecting rod; Copper sheathing peripheral hardware in the plunger pump is separated water channel, and oiling valve and outlet valve are installed in the pump.
The advantage of this product is to save the power and the energy.Through practice test, with " lever rocking arm power energy saving plunger hydraulic pump " and existing pressure hydraulic pumping unit in same machinery, under equal working environment, equal operating time and equal workload condition relatively: " lever rocking arm power energy saving plunger hydraulic pump " can effectively save fuel oil more than 30 percent, and suitable application prospects is arranged.Especially suit using on the engineering machinery such as excavator and on the ship power.
This product structure is simple, and is safe and reliable, the efficient height, and cost is low, implements easier, easy to operate.
Description of drawings
Fig. 1 is a kind of embodiment's plane structure of the utility model plan view.
Fig. 2 is the back pseudosection of Fig. 1.
Shown in the figure, 1, the pump housing 2, bent axle 3, connecting rod 4, connecting pin 5, lever rocking lever 6, locating stud 7, plunger 8, plunger pump 9, outlet valve 10, oil outlet 11, plunger cylinder 12, oiling valve 13, water channel 14, oil inlet hole 15, copper sheathing 16, plunger pump connecting rod 17, plate washer 18, connecting cover.
Embodiment
Establish a bent axle 2 in the pump housing 1 of the present utility model, separate on the bent axle 2 four bearings and three pitman shafts that connecting rod 3 is housed respectively are installed, article three, connecting rod 3 connects lever rocking lever 5 respectively by connecting pin 4, the other end that is the lever rocking lever 5 in the pump housing 1 neck and neck connects upper and lower two plunger pump connecting rods 16 by locating stud 6, the other end of plunger pump connecting rod 16 is fixed a plunger pump 8 respectively, promptly a lever rocking lever 5 connects upper and lower two plunger pumps 8 respectively, plunger pump 8 is operation up and down respectively, makes in the work oil-feed oil extraction stable.Crankshaft direction is variant, spin balancing.The utility model is provided with many bent axles, by the many bent axles many connecting rods that turn round, drives many lever rocking arms and the work of interlock plunger pump up and down.During work, above three pumps arranged side by side be one group, three following pumps are one group, respectively a chain of work keeps each pump oil extraction balance.
Plunger 7 bottom fixed connecting rods 16 in the plunger pump 8, pump collar extension end sets out fuel tap 9, oil outlet 10, establishes oiling valve 12 and be located at the separation water channel 13 that plays cooling action outside the copper sheathing 15, the protruding oil inlet hole 14 in below in cylinder body 11.Because oiling valve as safe as a house and outlet valve are installed, hydraulic oil is burnt one's bridge at work.Peripheral hardware plate washer 17 between the plunger pump 8 up and down, there is connecting cover 18 bent axle 2 outer ends.
Claims (1)
1, a kind of lever rocking arm power energy saving plunger hydraulic pump includes the plunger pump of turnover oilhole, plunger, cylinder body and bent axle, connecting rod, it is characterized in that:
