Abstract
The utility model relates to a totally-enclosed hydraulic pump station system which comprises an enclosed oil tank body, the enclosed oil tank body is connected with an inflatable bag through a flexible pipe, an oil port ball valve is arranged at an oil inlet of the enclosed oil tank body, and a vent valve is arranged at the position of an air outlet at the upper portion of the enclosed oil tank body. The totally-enclosed hydraulic pump station system has the beneficial effects that a totally-enclosed oil tank with a soft bag which is arranged on the totally-enclosed hydraulic pump station is used to inflate air inside so that a plurality of shortcomings for an air cleaner arranged on a common pump station are changed. Because an oil tank is of an enclosed structure, a pump station only exchanges gas with a bag when the pump station works. Meanwhile, the bag keeps pressure balance inside and outside the water tank through contraction and expansion of the bag, and accordingly working stability and durability of a system are improved, and cost is reduced.
Description
Technical field
The utility model relates to the hydraulic power unit technology, relates in particular to a kind of totally enclosed type hydraulic power unit system.
Background technique
Hydraulic power unit is as using a kind of very widely equipment in the modern mechanical industry; Needs because of the external acting of oil cylinder; Fluid in the fuel tank can the time few for a long time, for reaching the pressure balance inside and outside the fuel tank, all pumping plants all are equipped with air-strainer and come external respiration on its fuel tank; But, on-the-spot because of industrial environment, all contain dust and moisture in the air, pumping plant work is of a specified duration, and dust in air and moisture can enter in the fuel tank through air-strainer, cause oil contamination; In the environment of many dirt or humidity, this situation can be more serious especially; For this type of problem, at present, though the nitrogen of filling fuel tank is arranged, higher and working service is complicated because of its cost can't extensive use; Simultaneously, most hydraulic power units still are faced with the present situation of being polluted by environmental air and can't change.Therefore, to above aspect, need reasonably improve existing technology.
Summary of the invention
To above defective, the utility model provides a kind of sealing fully, can avoid oil contamination, helps the totally enclosed type hydraulic power unit system that practices thrift cost, can improve the stability of a system and serviceability, to solve many deficiencies of existing technology.
For realizing above-mentioned purpose, the utility model adopts following technological scheme:
A kind of totally enclosed type hydraulic power unit system; Comprise the closed tank body; Said closed tank body is connected with the inflation leather bag through flexible pipe, and the oil filler ball valve is equipped with at closed tank body filler opening place wherein, and the relief opening position that is positioned at this closed tank body upper end is provided with an outlet valve.
In addition, said inflation leather bag outside has the leather bag urceolus, on closed tank body and the pipeline of inflation leather bag between the two quick inserting joint is installed, and on the inflation leather bag two inflation inlets and an air vent is set.
The beneficial effect of the described totally enclosed type hydraulic power unit of the utility model system is: the total closed oil tank through band moccasin capsule is set carries out inner inflatable; Changed many shortcomings of the air-strainer of being installed on the common pumping plant, because of fuel tank is all-sealed structure, this makes pumping plant when work; Only with the leather bag exchanging gas; Leather bag keeps the pressure balance inside and outside the fuel tank through the contraction of self with expanding, thereby has improved working stability, the durability of system self, has reduced cost.
Description of drawings
According to accompanying drawing the utility model is done further explain below.
Fig. 1 is the structural representation of the said totally enclosed type hydraulic power unit of the utility model embodiment system.
Among the figure: 1, closed tank body; 2, oil filler ball valve; 3, outlet valve; 4, quick inserting joint; 5, inflation leather bag; 6, leather bag urceolus; 7, pressure gauge; 8, inflation inlet; 9, air vent.
Embodiment
As shown in Figure 1; The described totally enclosed type hydraulic power unit of the utility model embodiment system; Comprise closed tank body 1; Said closed tank body 1 be connected with the inflation leather bag 5 that has outside leather bag urceolus 6 through flexible pipe and casing and air bag this two between pipeline on quick inserting joint 4 is installed, oil filler ball valve 2 is equipped with at closed tank body 1 filler opening place wherein, is set up in parallel two inflation inlets 8 and an air vent 9 on the inflation leather bag 5 wherein; Simultaneously, the relief opening position that is positioned at this closed tank body 1 upper end is provided with an outlet valve 3, and the hose end between closed tank body 1 and inflation leather bag 5 is installed a pressure gauge 7.
The described totally enclosed type hydraulic power unit of above the utility model embodiment system, outlet valve 3 is wherein opened when need refuel, and leather bag places in the urceolus to prevent that leather bag from rolling when breathing; When fluid in the fuel tank reduced, the leather bag air flowed to fuel tank, and leather bag is compressed by ambient air, guarantees not have in the fuel tank negative pressure; When the fuel tank inner fluid increases, gas flow leather bag in the fuel tank, leather bag is filled greatly, still keeps barometric pressure; Gas diminishes because of cause specific all the time in leather bag, so that when being lower than barometric pressure, pressure gauge with electric contact is reported to the police; Can be artificial or use electrical switch, through the inflation inlet inflation, if there is not the manual inflation; When pressure further reduced, inflation inlet can overcome spring setting power to be opened automatically, charges into air; When gas in the leather bag is higher than barometric pressure all the time, when height to certain value, air vent overcomes spring and sets the power automatic deflation.
Above embodiment is more preferably embodiment a kind of of the utility model, and common variation that those skilled in the art carry out in present technique scheme scope and replacement should be included in the protection domain of the utility model.
