Abstract
The utility model relates to a hydraulic oil pressure control and oil recycling device which comprises a hydraulic oil outlet pipeline. A hydraulic oil pump and a pressure control safety valve are mounted on the hydraulic oil outlet pipeline, an oil return pipeline is connected on the pressure control safety valve, a hydraulic oil storage tank is connected at the end of the oil return pipeline, the hydraulic oil outlet pipeline is divided into two branches, the hydraulic oil pump and the pressure control safety valve are mounted on the two branches respectively, and the maximum bearing pressure of the pressure control safety valve is 7MPa. The set pressure of the pressure control safety valve is 7MPa, oil can return to the hydraulic oil storage tank through the oil return pipeline from a pressure control valve outlet once a pressure value is higher than a set value, so that the oil pressure is not too high, stability of the outlet pressure and fine flowability of the oil are ensured, and waste of the hydraulic oil is avoided.
Description
Technical field
The utility model relates to a kind of auxiliary device of polypropylene production equipment, particularly relates to a kind of hydraulic fluid pressure and controls and oily reclamation set.
Background technique
At present, in polyacrylic production process, hydraulic oil is the important leverage of each pump running of device, but in hydraulic fluid pressure control procedure, owing to being subject to the impact of extraneous electrical tracing oil supply heating.The oil pressure of hydraulic oil can raise along with the rising of temperature simultaneously.When normal, oil pressure is controlled at 6MPa left and right, but temperature influence can reach the pressure about 10MPa sometimes, so to some equipment and pipeline, can cause because building the pressure for a long time certain infringement.
Based on this, make the utility model.
Model utility content
For the problems referred to above, the purpose of this utility model is hydraulic fluid pressure to be set on the outlet line of hydraulic-pressure pump control and oily reclamation set, guarantees outlet pressure control within the specific limits, the safety of assurance equipment and pipeline.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of hydraulic fluid pressure is controlled and oily reclamation set, comprise hydraulic oil outlet line, on described hydraulic oil outlet line, hydraulic-pressure pump and pressure controlled safety valve are installed, are connected with oil return pipeline on described pressure controlled safety valve, the end of described oil return pipeline is connected with hydraulic oil storage tank.
Described hydraulic oil outlet line is divided into two branch roads, and described hydraulic-pressure pump and pressure controlled safety valve are arranged on respectively on two branch roads.
It is 7MPa that described pressure controlled safety valve maximum is born pressure.
The beneficial effects of the utility model are as follows:
Hydraulic fluid pressure of the present utility model is controlled and oily reclamation set, on hydraulic oil outlet line, pressure controlled safety valve has been installed, pressure controlled safety valve setting pressure is at 7MPa, once pressure is higher than setting value, oil just can export from pressure controlled valve, by oil return pipeline, come back to hydraulic oil storage tank, guarantee that oil pressure is too not higher, guaranteed stable and oil mobility good of outlet pressure, also guaranteed not wasting of hydraulic oil simultaneously.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Wherein, 1 is that hydraulic oil outlet line, 2 is that pressure controlled safety valve, 3 is that oil return pipeline, 4 is that hydraulic oil storage tank, 5 is hydraulic-pressure pump.
Embodiment
Below in conjunction with specific embodiment, the utility model is further described, but protection domain of the present utility model is not limited to this.
As shown in Figure 1, hydraulic fluid pressure of the present utility model is controlled and oily reclamation set, comprise hydraulic oil outlet line 1, hydraulic-pressure pump 5 and pressure controlled safety valve 2 are installed on hydraulic oil outlet line 1, on pressure controlled safety valve 2, be connected with oil return pipeline 3, the end of oil return pipeline 3 is connected with hydraulic oil storage tank 4.
For reaching better pressure, control and oily reuse effect, in the utility model, hydraulic oil outlet line 1 is divided into two branch roads, and hydraulic-pressure pump 5 and pressure controlled safety valve 2 are arranged on respectively on two branch roads.
In the utility model, to bear pressure be 7MPa to pressure controlled safety valve 2 maximums.
Hydraulic fluid pressure of the present utility model is controlled and oily reclamation set, by controlling safety valve 2 at the rear setting pressure of hydraulic oil outlet line 1, installs oil return pipeline 3 additional in pressure controlled safety valve 2 outlets simultaneously, oil return pipeline 3 is connected to hydraulic oil storage tank 4 simultaneously.At the pressure of normal condition hydraulic oil, controlling is by automatic start-stop hydraulic-pressure pump 1, control its outlet pressure, general pressure is controlled at about 5.5 to 6.5MPa, but for guaranteeing oil mobility, on hydraulic oil outlet line 1, heat traced pipeline is housed, rising along with oil temperature, oil pressure also can rise simultaneously, too not higher for guaranteeing oil pressure, pressure controlled safety valve 2 setting pressures that install additional on hydraulic oil outlet line 1 are at 7MPa, once pressure is higher than setting value, oil just can be from pressure controlled safety valve 2 outlets, by oil return pipeline 3, come back in hydraulic oil storage tank 4, guarantee that oil pressure is too not higher, guaranteed stable and oil mobility good of outlet pressure, also guaranteed not wasting of hydraulic oil simultaneously.
Above-described embodiment is only for the inventive concept of the present utility model of explaining, but not restriction to the utility model rights protection, allly utilizes this design to carry out the change of unsubstantiality to the utility model, all should fall into protection domain of the present utility model.
Claims (3)
