Abstract
The utility model relates to pumps in engineering machinery, in particular to a mining sinking pump, which is characterized in that a corrugated pipe made of nylon or plastic and an airbag type expansion unit are respectively connected to the upper end and the lower end of a communicating pipe and filled with liquid so as to form a vertical closed communicating vessel. The corrugated pipe at the upper end is connected with a transmission mechanism, and the expansion unit at the lower end is mounted in a drum type hydraulic cylinder which is equipped with a suction valve, a discharge valve anda discharge pipe. When the corrugated pipe is driven to expand and contract by the transmission mechanism to cause changes of volume, the expansion unit at the other end of the communicating pipe expands or contracts in the hydraulic cylinder in the same period along with the changes of volume, thereby changing space inside the hydraulic cylinder and having functions of sucking and discharging liquid.
Description
Technical field
The utility model relates to the pump in the engineering machinery.
Background technique
Existing mining deep water pump is as the picotan of more piece centrifugal pump, submersible pump, liquid jetting device and centrifugal pump combination etc.Downhole hardware is more, complex structure, and the cost height, water intaking has certain narrow limitation.
The model utility content
The utility model provides a kind of mining deep water pump that utilizes the law of connected vessels water lift or draw water, and the water lift degree of depth can reach ten meters even tens meters, simple in structure, cost is low, easy to use, have wide range of applications.
Feature of the present utility model is that bellows and elasticity air sac type breathing preferably device that nylon or plastics are made are connected on the top and bottom of connecting tube respectively, and fills liquid therein, forms the airtight connecting vessels that stands vertically.The bellows of upper end is connected with driving mechanism, the breathing device of lower end be installed in have suction valve, in the cartridge type liquid cylinder of expulsion valve and discharge tube.When driving mechanism drives that bellows is flexible to produce Volume Changes, connecting tube the breathing device of the other end also expand and shrink along with in liquid cylinder, doing with the same cycle, cause the Volume Changes of fluid cylinder intracorporeal space, play the effect of suction and drain.
Description of drawings
Fig. 1 is an embodiment's of the utility model a structural representation.
Among the figure: 1 bellows, 2 connecting tube, 3 discharge tubes, 4 breathing devices, 5 liquid cylinders, 6 expulsion valves, 7 suction valves, 8 traffic valves, 9 rocking bars, 10 gears, 11 transmission shafts, 12 rotatingshafts.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.What accompanying drawing provided is the mining deep water pump structure with A, two connecting vesselss of B.Upper end in connecting tube 2 connects bellows 1, and the lower end connects breathing device 4, and water is filled in its inside, sealing back, forms airtight connecting vessels.Breathing device 4 is installed in the liquid cylinder 5 with suction valve 7 and expulsion valve 6.When utilizing motor or other power to make rocking bar 9 rotate moving axis 12 when shaking by gear 10, the transmission shaft 11 that is connected on the rocking bar makes the bellows 1 of connecting vessels A and connecting vessels B make reciprocal fore and aft motion up and down respectively.
When the bellows among the connecting vessels B 1 is compressed volume-diminished, compressed this volume ground water, by entering connecting tube 2 breathing device expanding volume is increased, occupy the space in the liquid cylinder 5, the water in the liquid cylinder is depressed into discharge tube 3 and discharges the pump housing by expulsion valve 6.At this moment, the volume that stretched of the bellows 1 among the connecting vessels A increases, and the water in the breathing device 4 is brought up made that the breathing body is long-pending to be dwindled, and has increased the space in the liquid cylinder 5, causes liquid cylinder inner with extraneous pressure difference, thus with water in suction valve 7 inhalant liquid cylinder bodies.So do action reaches the purpose of continuous suction and extrusion liquid.
Can be provided with traffic valve 8 between connecting vessels A and connecting vessels B, when pump startup, required power when opening the traffic valve and can reduce to start treats that pump work just often closes the traffic valve.
General water pump is all to cause the pressure difference in the external atmosphere pressure and the pump housing to obtain the degree of depth that absorbs water, and the degree of depth that therefore absorbs water is difficult to reach below ten meters.But working principle difference of the present utility model, and liquid cylinder is to be directly installed in the water that is absorbed water, therefore the water lift degree of depth of this pump only is directly proportional with the size of applied external force.This pump can make full use of the gravitational potential energy of water simultaneously, discharges the gravitational potential energy of water outlet immediately when the bellows stretching travel finishes, and makes the volume of bellows compression and increase breathing device, and the hydraulic pressure in the pump housing is gone out outside the discharge tube.The structure that embodiment provides has reached the gravitational potential energy that rationally utilizes water, makes the part number of pump and cost all be lower than existing deep water pump class, and is simple and reasonable.
Claims (1)
