Specific embodiment
As shown in Figure 1, for the hydraulic oil container provided by the embodiment of the utility model for being suitable for extremely cold environment, the hydraulic oil container
It can be used for the relevant devices such as continuous miner, development machine.As shown in Figure 1, the hydraulic oil container of the present embodiment includes: for storing liquid
The cabinet 1 of pressure oil；The gear pump 5 being mounted on cabinet 1 and the gear pump motor 2 being connect with gear pump 5；One end is inserted in case
Fuel sucking pipe 7 in body 1, the other end are connected with the inlet port of gear pump 5；It is connected to oil outlet and 1 oil return of cabinet of gear pump 5
The oil return line of mouth；The overflow valve 6 being mounted on oil return line；The heating for being used to heat its interior hydraulic oil of connection fuel sucking pipe 7
Device；The temperature sensor 9 for hydraulic fluid temperature in detection box 1 being mounted on cabinet 1；The use being mounted on cabinet 1
In the insulating layer 10 for keeping hydraulic fluid temperature in cabinet 1；It is electrically connected with gear pump motor 2, resistance heater, temperature sensor 9
Controller, for being fed back according to temperature sensor 9 temperature data control gear pump motor 2, resistance heater opening and closing.
Specifically, the hydraulic oil container of the present embodiment by cabinet 1, gear pump motor 2, ring flange 3, shaft coupling 4, gear pump 5,
The composition such as overflow valve 6, fuel sucking pipe 7, heating device, temperature sensor 9, insulating layer 10, cover board 11.
Wherein, cabinet 1 is the shell with opening of the cuboid made of low temperature resistant steel, and insulating layer 10 is by protecting
The good thermal insulation material of temp effect is made, and is extruded on cabinet 1 by cover board 11, can effectively keep the temperature, and prevents hydraulic oil in cabinet 1
Oil temperature decline it is too fast, and cover board 11 is bolted on the opening of cabinet 1.
Gear pump motor 2 is connected with gear pump 5 by ring flange 3 and shaft coupling 4, and ring flange 3 is bolted
On cabinet 1, so that gear pump motor 2 and gear pump 5 is fixed.Lead between the oil outlet of gear pump 5 and the oil return opening of cabinet 1
Oil return line connection is crossed, overflow valve 6 is provided on oil return line, and overflow valve 6 can be bolted on cabinet 1.
7 one end of fuel sucking pipe is inserted into the hydraulic oil of cabinet 1, and is fixed in cabinet 1 by flange bolt, in fuel sucking pipe 7
Be equipped with 5 inlet port of gear pump and mining equiment main oil pump inlet port, can by oil pipe by fuel sucking pipe and 5 inlet port of gear pump and
