Abstract

A redundant array pumping system and control system is provided for water rides for ensuring continuous and non-disruptive supply of water. The pumping system incorporates a redundant pump and filter array in conjunction with a nozzle system for injecting water onto a ride surface. The nozzle system may incorporate a plurality of redundant or quasi-redundant nozzles. The hydraulic system can include many levels of redundancy as applied to its various components, such as pumps, filters and nozzles. Additionally, the system can be equipped with a plurality of pressure and flow sensors for monitoring and controlling the performance of the pumps, filters and nozzles of the hydraulic system.

Claims (17)

1. A hydraulic system for a water ride, comprising:

a first primary pump hydraulically connected to a first supply conduit so that the first primary pump delivers pressurized water to the first supply conduit;

a second primary pump hydraulically connected to a second supply conduit so that the second primary pump delivers pressurized water to the second supply conduit;

the first and second primary pumps and first and second supply conduits arranged so that a flow of pressurized water from the first primary pump to the first conduit is isolated from a flow of pressurized water from the second primary pump to the second conduit;

an auxiliary pump;

a pump bypass manifold; and

a plurality of valves;

wherein the valves are arranged relative to the pumps and manifold so that, through selective actuation of the valves, the first primary pump can selectively be disconnected from the first conduit and in its place the auxiliary pump can be selectively connected via the pump bypass manifold to the first conduit so that the auxiliary pump delivers pressurized water to the first conduit in place of the first primary pump and a flow of pressurized water from the auxiliary pump to the first conduit is isolated from the flow of pressurized water from the second primary pump to the second conduit.

2. A hydraulic system as in claim 1 , wherein the first primary pump is adapted to deliver pressurized water only to the first conduit.

3. A hydraulic system as in claim 1 , wherein the plurality of valves are arranged relative to the pumps and manifold so that, through selective actuation of the valves, the first primary pump can be selectively hydraulically reconnected to the first conduit, and the second primary pump can be selectively hydraulically disconnected from the second conduit and in its place the auxiliary pump can be selectively hydraulically connected via the pump bypass manifold to the second conduit so that the auxiliary pump delivers pressurized water to the second conduit in place of the second primary pump and a flow of pressurized water from the auxiliary pump to the second conduit is isolated from the flow of pressurized water from the first primary pump to the first conduit.

4. A hydraulic system as in claim 3 additionally comprising a first primary filter in a series arrangement with the first primary pump, and a second primary filter in a series arrangement with the second primary pump.

5. A hydraulic system as in claim 4 additionally comprising an auxiliary filter, a filter bypass manifold, and a plurality of valves, wherein the valves and filter manifold are arranged so that through selective actuation of the valves, the first primary filter can selectively be removed from the series arrangement with the first primary pump and in its place the auxiliary filter can selectively be connected in series with the first primary pump via the filter manifold.

6. A hydraulic system as in claim 1 in combination with a water ride comprising a ride surface having a start point and an end point, the hydraulic system having a first nozzle and a second nozzle disposed on or adjacent the ride surface, wherein the first nozzle is disposed nearer the start point along the ride surface than is the second nozzle.

7. A hydraulic system as in claim 6 , wherein the first conduit is adapted to deliver pressurized water to the first nozzle and the second conduit is adapted to deliver pressurized water to the second nozzle.

8. A hydraulic system as in claim 7 , wherein the first and second conduits are hydraulically isolated from one another.

9. A hydraulic system as in claim 7 additionally comprising a control system adapted to control the supply of pressurized water through the first and second nozzles, wherein the supply of water delivered to the first nozzle can be adjusted independently of the supply of water through the second nozzle.

10. A hydraulic system as in claim 1 , wherein the system comprises N primary pumps and x auxiliary pumps, and each auxiliary pump is arranged to selectively replace any one of the primary pumps.
