Background technology
At present, the colliery powerful device is used very extensive, and operation has obtained approval and extensive use in the industry under the condition that ventilation condition is better under the ore deposit, pumping equipment is more complete.Yet, the most of dash condition of China's coal-mine is relatively poor, the environment on coalface temperature is greater than 35 ℃, and therefore, the powerful device temperature rise in running of existing colliery is very fast, if cooling cooling provision effect is undesirable, then can have a strong impact on the operating efficiency of coal mine equipment.The cooling system of existing colliery powerful device mainly contains following deficiency:
1, adopt open cooling system, the temperature of cooling fluid is affected by environment bigger, so cooling effect and the environment temperature degree of correlation are bigger, and the complete machine cooling effect is not good, and fault rate is higher, influences production efficiency;
2, the apparatus cools water directly is emitted on the operation working face, causes working face to form water damage, has a strong impact on the working face operating efficiency;
3, adopt modes such as entrusting cooling tower will cause coal mine equipment to be subjected to pushing away the restriction of band water pipe, under the colliery, move constantly, cause the serious burden of transporting.
Summary of the invention
In view of this, the present invention is intended to propose a kind of coal mine equipment and cooling system thereof, and is low and then influence the problem of operating efficiency with the cooling system cooling effectiveness that solves existing coal mine equipment.
For achieving the above object, technical scheme of the present invention is achieved in that
On the one hand, the invention provides a kind of cooling system of coal mine equipment, comprise cooling unit, the cooling fluid tank that is arranged on the coal mine equipment and the equipment group that is cooled, the described equipment group that is cooled comprises a plurality of by coolant duct series connection and/or the parts that are cooled in parallel, the described equipment group that is cooled, cooling unit and cooling fluid tank constitute closed circuit by the coolant duct series connection, and described cooling unit and the described pipeline that is cooled between the parts are provided with flow divider.
Further, the series loop at the described equipment group that is cooled, cooling unit, cooling fluid tank is provided with switch valve.
Further, described switch valve is arranged on described cooling unit and the described pipeline that is cooled between the equipment group.
Further, the described pipeline that is cooled between equipment group and the described cooling fluid tank is provided with filter.
Further, described cooling fluid is liquid medium.
Further, described cooling fluid is the mixture of water, bittern or ethylene glycol and water.
Further, described cooling unit comprises cooler and the water pump that is connected in series.
On the other hand, the present invention also provides a kind of coal mine equipment, and described coal mine equipment is provided with the cooling system of aforesaid coal mine equipment.
With respect to prior art, the present invention has following advantage: the cooling system of coal mine equipment of the present invention is because adopting closed circulation system, cooling fluid is subjected to ectocine less, therefore cooling effect is better, and each cooling-part can also be regulated the flow of cooling fluid by flow divider, the coolant rate of parts of being cooled faster heating up is transferred big, to strengthen cooling effect, the coolant rate of the slower parts that are cooled that heat up is turned down, to save cost, and then improve whole cooling effectiveness, reduce breakdown rate, and save cooling cost; On the other hand, because adopt closed circulation system, also need not externally to discharge cooling fluid, reduced the discharge pressure of operation working face, realize few aquation of working face, and then can improve operating efficiency.
