The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.
Piston type filling industrial pump hydraulic system according to one embodiment of the invention is described in detail in the following with reference to the attached drawings
The piston type filling industrial pump hydraulic system comprises a power device 100, wherein the power device 100 is formed by connecting at least two power units 110 in parallel, each power unit 110 comprises an oil tank 120 and a motor oil pump group 130, each motor oil pump group 130 comprises an oil tank 120, a main oil pump and a constant pressure pump, the power units 110 are pairwise and oppositely arranged, and the power units 110 are closely attached and arranged side by side;
in this embodiment, the power device 100 is provided with four power units 110, the arrangement of the power units is as shown in fig. 1, one end of the oil tank 120 is attached between the two power units 110, one end of the motor oil pump unit 130 is far away, and the power units 110 are closely arranged, so that the occupied space is saved, and the power device can be better arranged in a small space.
The pumping device 200 is connected with the power device 100 through a pipeline, the pumping device 200 comprises a main valve group 210, a distribution valve group and an S pipe valve pump 230, the main valve group 210 receives power from a main oil pump and provides the power to the S pipe valve pump 230, and the distribution valve group receives power of a shunt oil pump to control the S pipe valve pump 230 to change directions. For example, referring to fig. 3, the main valve set 210 is connected to the power plant 100 through an oil pipe, specifically, the main valve set 210 is communicated with the main oil pump, directly receives power from the main oil pump, and transmits the power to the S-pipe valve pump 230, and the main oil pump has a large flow rate to supply power for the S-pipe valve pump 230 to transport materials. The distribution valve bank is connected with a shunt oil pump, the flow rate of the shunt oil pump is relatively small, and the distribution valve bank is only used for supplying the shunt valve bank 140 to control the reversing of the S-pipe valve pump 230.
In the embodiment, the power unit 110 adopts a combination of 355 oil pumps and 260 oil pumps, the flow rate reaches 2400L/min, and the area ratio of the main oil cylinder to the conveying cylinder is improved, so that the transportation requirement of large square quantity is fully met. The combination of multiple power units 110 increases the amount of redundancy in the system and allows continued use when a single power unit 110 is damaged.
In this embodiment, the shunting oil pump is composed of a constant pressure pump and a gear pump, which are respectively 28 pumps and 22 pumps, and the shunting oil pump sucks oil from the oil tank 120 and then shunts the oil to four paths through the shunting valve bank 140, wherein the two paths are converged by the confluence steel pipe and then are delivered to the S-pipe valve pump 230; and the other way flows to the oil tank 120, and a radiator 300 is arranged in the pipeline, for example, referring to fig. 2, the radiator 300 can reduce the oil temperature, so that the overall temperature of the system can be better controlled, and the influence of overheating on the operation of the system can be avoided.
It is understood that, in order to control the oil temperature, a temperature sensor is disposed in the oil tank 120, and detects the oil temperature, and when the temperature of the system reaches a certain set value, the radiator 300 is automatically activated or deactivated to control the current oil temperature.
The fourth oil flowing out of the flow dividing valve block 140 flows to the oil tank 120, and an oil return filter 330 is provided in the pipeline, for example, referring to fig. 2, the oil path circulates through the oil return filter 330, thereby filtering impurities in the oil path system to maintain the cleanliness of the system.
According to some embodiments of the present invention, the main valve block is composed of four two-way inserts, and the flow rate can reach 4000L/min, which meets the requirement of large-volume transportation, for example, referring to fig. 4, the main valve block is composed of four two-way inserts, thereby increasing the flow rate of the valve block and meeting the requirement of large-volume transportation.
According to some embodiments of the present invention, a heater 310 for heating hydraulic oil is disposed in the oil tank 120, for example, referring to fig. 2, when the ambient temperature is low, the hydraulic oil is poor in fluidity, and the system is difficult to start. In order to ensure that the system can be normally started in a low-temperature state, the electric heater 310 is arranged in the oil tank 120, when the ambient temperature is lower than minus five degrees, the heater 310 automatically starts to heat the hydraulic oil to 15 degrees, and then the oil pump is started, so that the hydraulic elements can be protected under the condition of low viscosity of the hydraulic oil, and the service life of the system is prolonged.
According to some embodiments of the present invention, an energy storage assembly 320 is disposed on the oil inlet of the distribution valve block. For example, referring to fig. 2, the distribution valve block is driven by hydraulic oil, and the oil inlet of the distribution valve block refers to an oil inlet through which the hydraulic oil is introduced to change the direction of the distribution valve block, rather than the controlled end. Because the whole flow of the system is large, and the power required by the reversing of the distribution valve group is large, the energy storage component 320 is arranged, and the reversing pressure is improved. Normally, the energy storage assembly 320 is stamped by a constant pressure pump in the shunt oil pump, and the reversing process is completed by releasing pressure through the energy storage assembly 320. Specifically, the energy storage assembly 320 includes four energy storage devices connected in series, and the four energy storage devices are connected in series to improve overall pressure, so as to ensure normal operation of the reversing.
According to some embodiments of the invention, the main valve block 210 is made up of an integrated valve block, inside which all the pipes are drilled. Compared with a common hydraulic pipeline, the valve block can reduce leakage points of a hydraulic system, avoid leakage, reduce connecting pipelines and facilitate maintenance. Meanwhile, the layout can be simplified, and the occupied space is reduced, so that the system is neat and attractive.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the gist of the present invention.
