Description

Technical Field

[0001] The utility model relates to the field of filling machinery, in particular to a double-layer large-flow hydraulic power station. Background Art

[0002] As the country has greatly strengthened its efforts in environmental protection, most companies now use solid waste such as mine tailings, crushed stone, fly ash, industrial slag, etc. to make a paste-like slurry that does not require dehydration, and then continuously transport it to the underground goaf for filling through filling industrial pumps. This can not only increase the resource extraction rate, but also reduce land occupation and environmental pollution.

[0003] With the widespread application of filling industrial pumps, the requirements for the pumping volume of existing filling industrial pumps are getting higher and higher for the annual output of different mines. Obviously, the large demand for volume also requires a large flow rate for the hydraulic power station. The current large-displacement power station has the defects of scattered layout of oil tanks, motors, pumps and other components, large floor space, complex pipelines, and difficulty in use and maintenance. Therefore, a double-layer large-flow power station is developed to meet market demand. Utility Model Content

[0015] The utility model is further described below:

[0016] The power station of the utility model is composed of a chassis, an oil tank, a motor oil pump group, a radiator assembly and connecting pipes. The double-layer large-flow hydraulic power station of the utility model is characterized by a large system flow (4400m3 / min). The overall design adopts a detachable superimposed design with two layers. One motor group drives four 190-displacement hydraulic pumps through a transfer case. Four groups of motors drive the oil pumps at the same time to merge. The overall hydraulic system adopts return oil filtration. The oil tank is equipped with a ladder and a top fence. Two oil pumps share an oil suction self-sealing device. The overall structure is beautiful and easy to maintain. The power station adopts the design concept of superimposing two layers, and the overall space is small.

[0017] The oil pump motor group is mainly composed of a three-phase asynchronous motor, a transfer case, an oil pump, a coupling, etc. The system uses a 450KW motor to drive 4 groups of 190 oil pumps + 190 oil pump main pumps through a speed increase transfer case, and the overall design adopts a four-group motor design. The power station adopts air cooling as a whole. Considering the huge space occupied by the radiator, the utility model changes the radiator to a top-mounted air suction heat dissipation. The utility model adopts return oil filtration, the system flow is large, and the return oil filter is installed in an up and down ladder arrangement.

[0018] In summary, the utility model takes into account the need to meet the flow rate while occupying a small space, so when designing the hydraulic power station, the 4 motor oil pump groups are designed in a two-layer stacking design, the oil tank return oil filter is arranged in a stepped manner, and the transfer case drive method is adopted. Four 450KW motors are used as the main power driving source. Each motor drives 4 main oil pumps through the transfer case. The main oil pump (190 pump + 190 pump) of the motor oil pump group sucks oil from the oil tank through the oil pump high-pressure oil outlet and simultaneously delivers oil to the high-pressure oil pipe. After converging through the high-pressure oil pipe, it enters the valve group and is then delivered to the actuator (the oil inlet of the main oil pump is connected to the oil tank through the oil suction self-sealing device, and then the oil outlet of the main oil pump is connected to the high-pressure oil pipe). A temperature sensor is installed on the oil tank. When the temperature of the system reaches a certain set value, the radiator automatically starts and stops to maintain the oil temperature of the system.

[0019] Compared with the prior art, the utility model has the following beneficial effects:

[0020] The double-layer large-flow hydraulic power station of the utility model integrates various hydraulic components into a whole on the basis of meeting the use requirements of large-flow and high-pressure hydraulic systems, thereby reducing external pipelines. The power station has a compact structure, a reasonable layout, and is easy to use and maintain, and has high working reliability. BRIEF DESCRIPTION OF THE DRAWINGS
