Why are there multiple cylinders in a piston pump?
Practical piston pumps therefore employ multiple cylinders and pistons to smooth out fluid delivery, and much ingenuity goes into designing multicylinder pumps which are surprisingly compact. The displacement of a piston pump can be easily calculated:
How are pistons kept in contact with the swash plate?
The pistons are stroked by a fixed angled plate called the swash plate. Each piston can be kept in contact with the swash plate by springs or by a rotating shoe plate linked to the swash plate. Figure 2.14. Axial pump with swash plate
What causes the barrel of a piston pump to rotate?
This torque causes rotation of all elements ending in the barrel, which is allowed to rotate within the yoke of the pump. The centre shaft of the barrel is fixed to the yoke, which is nonrotating about the centreline of the main shaft. The yoke is allowed to rotate around an axis perpendicular to the main shaft.
How is the displacement of a piston pump calculated?
The displacement of a piston pump can be easily calculated: Figure 2.12 shows one form of radial piston pump. The pump consists of several hollow pistons inside a stationary cylinder block. Each piston has spring-loaded inlet and outlet valves.
What happens if the piston does not move up?
Water can NOT be compressed when the piston moves up. The resulting damage could include a hole in the cylinder wall, a hole in the piston head, blown out valves or a hole in the head. The water will go somewhere, and it will take the weakest route it can find. This is known as a hydro-locked engine.
Why does my Sea Doo engine keep sputtering?
Fearing the salt water would destroy the engine I flushed it out without the engine running. I think this caused more problems. I have removed the plugs numerous times, cleaned, sprayed, blown, used starting fluid but still the engine will only sputter from time to time. I think there is water in the carbs but I do not know how to remove them.
How to get water out of Sea Doo engine?
Leave the plugs out of the plug holes and ground, at least one of them to the head using an “electricians” screwdriver or a small piece of wooden broom handle. If not, you’ll experience the reason why mechanics hate working with coils…..40,000 volts is one hell of a jolt.
Why do I have water in my engine?
Crossing streams, lakes, and rivers that are too deep is another great way to get water in your engine. Carburetors and air-boxes are typically on the upper end of the engine so you’d have to be pretty deep to get water in there, but it can happen.
