Torque hydraulic motors is done by oil pressure and oil pressure is caused by the hydraulic pump. The hydraulic pumps produce higher pressure gets too much torque.
Not a lot. A fire fighting pump found on most fire engines is the centrifugal type. Other than the amount of water it may flow and the number of discharges it can supply, there is no difference (although I'm not sure what "ordinary centrifugal pump" refers to unless it is a trash or sump pump). Centrifugal type pumps weren't always used in the fire service, but they are the standard now because they can spin (they can pump or maintain pressure) even when there is no water actually flowing.
The "engine" part of a marine engine is the same as any other kind of engine. The difference is the cooling system, and there are two kinds: raw water and enclosed. Raw water systems are used on outboards and small pleasure boats with inboard engines. The engine's water pump sucks water out of the lake, runs it through the engine and puts it back in the lake. This works with a minimum of parts, until you get into boats that run in salt water. Would YOU want ocean water running through your engine? Neither would yachtsmen with expensive diesels. The enclosed cooling system uses a heat exchanger. There's a tank on the boat with a radiator in it. The engine pumps coolant through the radiator just like it would the radiator on a car. A second pump pulls water out of the ocean and feeds it into the tank to cool the radiator. There's more maintenance in this system (you have to be sure saltwater scale isn't blocking the heat exchanger and you've got more water pumps to deal with) but it is more reliable than feeding raw water into the engine.
the impeller of the pump, discharges the water of a steam or air or electric driven pumps.
This varies from pump to pump because centrifugal pumps can be designed for various applications. The maximum height a pump can pump water depends on size of pipe/water column, friction, power available etc. This is often reffered to as the head of the pump. A water company would probably have some centrifugal pumps capable pumping to over 300m in a 30 inch main.
torque setting for 91 cadillac water pump 4.9 engine?
This depends on what engine you are working on.
According to the chilton manual the 5 water pump bolts torque to 89 inch pounds. The four bolts that hold the water pump pulley torque to 18 foot pounds.
11ft lbs
The torque of a water pump bolt can be requested from the manufacturer. The Chevy Trailblazer has a high torque for the water pump bolt.
the torque you want to put on the water pump bolts are about 60 foot pounds of torque.
It's connected to the water bottle, halfway down towards the rear of the engine.
cam is set at 12 oclock ip pump is set at 3oclock crank is 6 oclock a aux is 9 oclock
Torque specs for WATER PUMP Mercedes 420 SEL are: 7.3 diesel and 15 to 18 foot pounds of torque
Fuel pump is what pumps gas to engine. Water pump is what pump water in engine
when changing the water pump it is also adviseable to change the timing belt as well.
The water pump is usually on the front of the engine.
