Description of drawings
The coal-winning machine that Fig. 1 provides for the utility model embodiment cleans and test water circulation system structural representation.
The specific embodiment
As shown in Figure 1, the utility model embodiment provides a kind of coal-winning machine to clean and test uses water circulation system, coal-winning machine 1 to be provided with water inlet 11 and delivery port 12, and this water circulation system comprises water tank 2 and emulsion pump 3.Water tank 2 includes an inlet and an outlet 21, the open top of the water tank 2 that opens wide namely can be as the entrance of water tank 2, the outlet 21 of water tank 2 is positioned at the bottom of water tank 2, be connected with the water inlet 11 of coal-winning machine 1 by inlet pipeline 4, the entrance of water tank 2 is connected with the delivery port 12 of coal-winning machine 1 by water return pipeline 5.Emulsion pump 3 is arranged between the water inlet 11 of the outlet 21 of water tank 2 and coal-winning machine 1, and the suction pipe of emulsion pump 3 links to each other with the outlet 21 of water tank 2, and the discharge pipe of emulsion pump 3 communicates with inlet pipeline 4, so that the water in the water tank 2 is drawn in the inlet pipeline 4.
The water tank 2 that the water circulation system that present embodiment provides arranges, its length is 9.5 meters, and wide is 2.2 meters, and height is 2.2 meters, and the top is uncovered, with water tank 2 water storages, when making municipal water occur cutting off the water, maintenance of equipment work can not be affected.Emulsion pump 3 can be selected the Leibo pump for use, and model is RMI S300, and the power of this pump is 224Kw, and supply voltage is 1140V.Simultaneously, this pump is furnished with the vacuum electromagnetic starter that model is QJZ-400/1140 (660) S.When coal-winning machine 1 is cleaned or tests, by emulsion pump 3 water that stores in the water tank 2 is pumped into coal-winning machine 1 via inlet pipeline 4, after cleaning or test were finished, water was recycled in the water tank 2 through water return pipeline 5.Like this, coal-winning machine 1 test or water for cleaning just can reuse, and have avoided the waste of water resource.
Because water tank 2 is open, sediments such as the grains of sand, chip or anvil cinder are fallen in the water tank 2 easily, enter the damage that emulsion pump 3 causes pump for fear of these sediments, preferably, outlet 21 places in water tank 2 arrange strainer 6, so that above-mentioned various sediments are filtered.
Further, water circulation system also comprises radiator 7, is arranged in the water return pipeline 5.Return water temperature is too high, and when repeating water, cooling effect is poor, and each motor temperature that can make coal-winning machine 1 is too high and cause the generation of coal-winning machine 1 fault.Arranging of radiator 7 can effectively reduce return water temperature, and open water tank also can play the effect of heat radiation simultaneously, thereby reduces return water temperature.
On the basis of above-described embodiment, this water circulation system also is provided with accumulator 8, be arranged between the water inlet 11 of emulsion pump 3 and coal-winning machine 1, and accumulator 8 communicates with inlet pipeline 4.Accumulator 8 claims auxiliary power source again, can assist emulsion pump 3 to guarantee discharge pressure, can also absorb high-pressure pulsating simultaneously.
Preferably also be provided with one way valve 9 between the outlet 21 of water tank 2 and the emulsion pump 3, the flow direction that is used for control inlet pipeline 4 water, thereby make the water in the water tank 2 flow to the suction pipe of emulsion pump 3 via inlet pipeline 4, and can be from emulsion pump 3 reverse reflux to water tank 2.
Further, above-mentioned inlet pipeline 4 and water return pipeline 5 are formed by sebific duct, and it is the sebific duct of DN20 that sebific duct can be selected model.
Because the pressure of test water is 40-100bar, for guaranteeing that sebific duct is not damaged under this hydraulic pressure, the highest withstand voltage that sebific duct can be set is 40MPa.
The coal-winning machine that the utility model embodiment provides cleans and test comes water storage with water circulation system by water tank is set, and when making municipal water occur cutting off the water, maintenance of equipment work can not be affected.The water that reclaims in the water tank can be recycling simultaneously, saved water resource.By the pressure that emulsion pump has guaranteed the water tank water outlet is set, thereby can guarantee the requirement of coal-winning machine test pressure.
It should be noted that at last: above embodiment only in order to the technical solution of the utility model to be described, is not intended to limit; Although with reference to previous embodiment the utility model is had been described in detail, those of ordinary skill in the art is to be understood that: it still can be made amendment to the technical scheme that aforementioned each embodiment puts down in writing, and perhaps part technical characterictic wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the scope of each embodiment technical scheme of the utility model.
