Abstract
A high pressure fluid delivery system is disclosed in which two or more dump guns, each having a high pressure nozzle outlet and a low pressure dump outlet, may be connected to and operated from a single high pressure pump. Pressure responsive flow control apparatus is provided in the flow line between each gun and the pump to maintain a substantially constant load on the pump even though the dump guns are randomly operated. A motor control apparatus is also provided for controlling the speed of an engine driving the pump and this apparatus is connected to the pressure responsive control apparatus through a shuttle valve so that the engine idles when all of the guns are dumping, but automatically runs at a faster speed when one or more of the dump guns is actuated to provide a high pressure fluid blast.
Claims12
A system for supplying a high pressure stream of fluid comprising:
- a pump having a low pressure inlet adapted to be connected to a source of fluid and a high pressure outlet;
- a prime mover drivingly connected to said pump and including a throttle for controlling the speed of operation of said pump;
- throttle control means connected to said throttle and adapted to respond to a control signal to move said throttle to vary the speed of said prime mover between a relatively fast speed and a relatively slow speed;
- at least two dump guns each including a fluid inlet, a relatively high pressure fluid outlet, a relatively low pressure fluid outlet, and actuating means for diverting flow between the fluid outlets of said guns;
- flow control means connected between the inlet of each gun and the outlet of said pump for maintaining a substantially constant load on said pump during random actuation of said actuating means;
- and
- means connected between said flow control means and said throttle control means for providing said control signal in response to actuation of at least one of said guns.
Apparatus for controlling the speed of operation of a pump driven by a prime mover wherein the pump is adapted to supply fluid to a plurality of randomly operated dump guns, comprising:
- first means connected between said pump and said guns for providing a substantially constant load on said pump during random operation of said guns;
- and
- second means connected to said prime mover for varying the speed of operation thereof in response to operation of said guns whereby the pump is driven at a relatively high speed when load demand is relatively high, and a relatively slow speed of operation when load demand is relatively low.
