Description
Technical field
The utility model relates to a kind of water supply installation, is specifically related to a kind of water lubriucated bearing draining pump lubricated water feeder for subsequent use.
Background technique
The pump shaft of deep-well pump is rubber bush bearing, relies on water to lubricate.The lubricated water investing method of current draining pump is to drop in the time of first 5 minutes of electric motor starting, to lubricate the rubber bush bearing of pump shaft, after outlet pipe there are flowing out, lubricated water just can stop supplying water, but in the time that water lubriucated bearing draining pump external lubrication water supply channel is cut off the water, cannot normally starting of draining pump, will cause sump to exceed the risk of warning stage.The lubricated water that drainage pumping plant uses at present is only obtained from outside water main, because the lubricated water that drainage pumping plant uses is only obtained from outside water main, in the time that outside supply channel need to be cut off the water, drainage pumping plant just cannot obtain lubricated water, thereby make draining pump cannot normally start work, in the time that sump exceeds warning stage, will cause danger.
Summary of the invention
For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of water lubriucated bearing draining pump lubricated water feeder for subsequent use, and this device can, at pump house in the time that external lubrication water supplies water interruption, provide lubricated water for subsequent use, to ensure the normal operation of draining pump.
The purpose of this utility model is achieved in that a kind of water lubriucated bearing draining pump lubricated water feeder for subsequent use, comprise feed main, total water pipe is provided with total water supply valve, total water pipe communicates with water storage box through isolation ball valve by lubricated water lines for subsequent use, be provided with outside water supply float switch in the outlet port of water storage box, the highest water level of water storage box is provided with a spill pipe, lowest order is provided with emptying ball valve, emptying ball valve is connected with spill pipe, the outlet pipe of water storage box is by water outlet ball valve, reduction valve, isolation ball valve, lubricated water water supply valve is connected with the lubricated water lines of pump motor group, on pumping line, be provided with an arm and pass through damper, anti-water supply ball valve and the anti-float switch that supplies water communicate with water storage box.
On water storage box, be provided with water-level gauge.
Between feed main and water supply main valve, be provided with total supply channel filter.
The problem that the water lubriucated bearing draining pump lubricated water feeder for subsequent use that the utility model provides cannot lubricate water pump while having solved water lubriucated bearing draining pump external water source water supply fault, provides lubricated water for subsequent use, makes draining pump energy reliable operation.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is inner rack structure schematic diagram of the present utility model.
Embodiment
Structure of the present utility model is as shown in Figure 1: a kind of water lubriucated bearing draining pump lubricated water feeder for subsequent use, comprise feed main 17, total water pipe 17 is provided with total water supply valve 14, total water pipe 17 communicates with water storage box 5 through isolation ball valve 13 by lubricated water lines 18 for subsequent use, be provided with outside water supply float switch 7 in the outlet port of water storage box 5, the highest water level of water storage box 5 is provided with a spill pipe 12, lowest order is provided with emptying ball valve 11, emptying ball valve 11 is connected with spill pipe 12, the outlet pipe of water storage box 5 is by water outlet ball valve 9, reduction valve 10, isolation ball valve 13, lubricated water water supply valve 16 is connected with the lubricated water lines of pump motor group 2, on pumping line 1, be provided with an arm by damper 3, anti-water supply ball valve 4 and the anti-float switch 6 that supplies water communicate with water storage box 5.On water storage box 5, be provided with water-level gauge 8.Between feed main 17 and water supply main valve 14, be provided with total supply channel filter 15.
Working principle of the present utility model is as follows:
(1) water storage box water-filling first: under external lubrication water water supply normal state, total water supply valve 14 is opened, to water storage box 5, by total water supply valve 14, total supply channel filter 15 water-filling first, in the time that the interior water level of water storage box 5 arrives designated water level (at least ensureing once to open pump institute water requirement), outside water supply float switch 7 cuts out.
(2) external lubrication water supplies water normal: do not need to use the water in water storage box 5 when normal when external lubrication water supplies water, close isolation ball valve 13, water outlet ball valve 9, the anti-ball valve 4 that supplies water, emptying ball valve 11, open total water supply valve 14 and lubricated water water supply valve 16, external lubrication water can be lubricated water pump.
(3) external lubrication water water pipe is cut off the water: in the time that external lubrication water water pipe is cut off the water, close emptying ball valve 11, total water supply valve 14, open isolation ball valve 13, water outlet ball valve 9, the anti-ball valve 4 that supplies water, the water that opens the front water storage box 5 of pump is lubricated water pump by water outlet ball valve 9, reduction valve 10, isolation ball valve 13 and lubricated water water supply valve 16.
After pump motor group 2 starts, on pumping line 1, drawing an arm supplies water to water storage box 5 by damper 3 and anti-water supply ball valve 4, in the time that the interior water level of water storage box 5 arrives designated water level (at least ensureing once to open pump institute water requirement), the anti-float switch 6 that supplies water cuts out, thereby provides lubricated water for opening pump next time.
(4) lubricated water turnaround of unit for subsequent use: when lubricated water turnaround of unit for subsequent use, close isolation ball valve 13, the anti-ball valve 4 that supplies water, open after emptying ball valve 11 is discharged the water of water storage box 5 inside it is overhauled.
Wherein the effect of reduction valve 10 is to limit the percolating water of discharging when deep-well pump opens pump to backflow into water storage box 5 by the lubricated water rising pipe of water storage box 5.3 of dampers are for reducing anti-water supply flow.The effect of spill pipe 12 is in order to prevent that cistern water level is too high and overflow from top.
