Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figures 1 to 3, it is intake chamber 1, pump tank 2 and work nest 3 by baffle for separating that the present invention makes the housing 11 of the device that hydrostatic circulates, and intake chamber 1, pump tank 2 and work nest 3 are rectangle; Intake chamber 1 is separated by first dividing plate 14 with pump tank 2, and work nest 3 is positioned at pump tank 2, and work nest 3 has one side coplanar with pump tank 2, and other three are separated by three second partitions 16; Three second partitions 16 wherein one parallel with the first dividing plate 14, all the other two are vertical with the first dividing plate 14.
The first dividing plate 14 between intake chamber 1 and pump tank 2 has the first circular through hole 10 near the position of bottom, and the effect of this first through hole 10 is for water is transported to work nest 3 from intake chamber 1.
Bottom centre position at work nest 3 has threaded hole, and its effect is in order to connect sparge pipe 9; On the second partition 16 of parallel the first dividing plate 14, have circular through hole, this through hole is radially provided with the first boss 6 towards the direction of sparge pipe 9, this first boss 6 is cylindrical, the centre of the first boss 6 have with second partition 16 on through hole coaxially with the circular hole in footpath (be through hole extend to the first boss 6) on second partition 16; The effect of this first boss 6 is in order to connect for the first communicating pipe 7, by the first communicating pipe 7 water in intake chamber 1 being introduced in sparge pipe 9.The second partition 16 of two vertical the first dividing plates 14 between work nest 3 and pump tank 2, have at least one in the position near top, to have the hole 13 being communicated with pump tank 2, the shape in this hole 13 can be definite according to actual conditions, and the effect in hole 13 is for the water flowing in intake chamber 1 in work nest 3 is entered in pump tank 2 by this hole 13.
The first communicating pipe 7 was a columniform rubber tube, and its one end is connected in the first boss 6, and the other end is connected in the second boss 8, and its effect is for the water in intake chamber 1 is introduced in work nest 3.
The top of work nest 3 is provided with cover plate 4, and this cover plate 4 is rectangle, on cover plate, can have a plurality of circular holes according to actual conditions, all overlaps rubber sleeve 5 in each circular hole, and the connecting line that is arranged in work nest 3 samples is passed by rubber sleeve 5.
Principle of work of the present invention is:
While using device of the present invention, water is introduced from intake chamber 1, be introduced into water in tank 1 successively by the first through hole 10 on the first dividing plate 14, entered in sparge pipe 9 the first communicating pipe 7; According to law of connected vessels, the water level of the water in introducing intake chamber 1 and flow into water level in sparge pipe 9 equal after, continue to add water in intake chamber 1, the water in sparge pipe 9 just can overflow, in inflow work nest 3.When the water level of the water in overflowing into work nest 3 is concordant with water surface elevation in sparge pipe 9, sparge pipe 9 is not just had under upstream face; Continuation adds water in intake chamber 1, and the water level in adding intake chamber 1 is during higher than the hole 13 on work nest 3 and pump tank 2 second partition 16 tops, and the water continuing to flow into is just from then in the 13 inflow pump tanks 2 of hole.When the water level in pump tank 2 reaches 1/2 height of second partition 16 between work nest 3 and pump tank 2, and the water level in intake chamber 1 is during higher than hole 13 setting height on work nest 3 and pump tank 2 second partition 16 tops, stops adding water; Open pumping water device 12, water in pump tank 2 is flowed in flow inflow intake chamber 1 identical in work nest 3 with intake chamber 1, like this, from open after pumping water device 12, water level in each groove just can remain unchanged, and realized and having circulated in the situation that total Water is constant, realized again the dynamic effect of water in work nest 3.
