Hydraulic Pump and Motor for Replacing 16HP Gas Engine

In summary, a hydraulic pump and motor can be used to replace a 16HP gas engine in various applications. These components work together to convert mechanical energy from the engine into hydraulic power, which can be used to operate machinery or equipment. This can be beneficial for reducing emissions and increasing efficiency, as well as providing a more compact and versatile power source. However, proper installation and maintenance is crucial for ensuring optimal performance and longevity of the hydraulic pump and motor.

need a hydraulic pump (gpm) ? to drive a hydraulic motor (torque)? - that has to replace a 16 horsepower gas engine - to drive a snowblower at 1000 rpm,s what is the formula for this? pump would be driven at arpox 3,000 rpm

The power from the pump, the hydraulic motor, the snowblower and the driving motor/engine must all be the same (taking into account their respective efficiencies). Power is conserve throughout the system.

Equations and calculators available http://www.surpluscenter.com/Hydraulic.htm" .

Torque needed by the 16 hp snowblower @ 1000 rpm is 1008 in.lb (Power = Torque X RPM / 63025).

Assuming 0.85 efficiency, the characteristics of the motor are (you need to know the operating pressure or the GPM):

GPM = Torque X RPM / PSI X 2 X pi / 231 / 0.85

GPM and PSI will be the same for the pump. Power and torque for the pump are (assuming 0.85 efficiency):

Power = PSI X GPM / 1714 / 0.85 --> according to the website: «HP is for electric motors, double this for gas engines.» Multiply by 746 to convert into Watt (electric motor).

Torque (ft.lb) = 5252 X Power / RPM

Displacement of the pump and motor (with their respective RPM):

Displacement (in³/rev) = GPM X 231 / RPM

1. What is a hydraulic pump and motor?

A hydraulic pump and motor is a mechanical device used to convert energy from a fluid flow into rotational motion. This is typically used to power heavy machinery and equipment, such as a 16HP gas engine.

2. Why would a 16HP gas engine need to be replaced with a hydraulic pump and motor?

There are several reasons why a 16HP gas engine may need to be replaced with a hydraulic pump and motor. One reason could be to improve efficiency and reduce emissions, as hydraulic systems are known for their high efficiency and low environmental impact. Another reason could be to provide more control and precision in powering specific equipment.

3. How does a hydraulic pump and motor work?

A hydraulic pump and motor work together in a closed loop system. The pump uses mechanical energy to create fluid flow, which is then directed to the motor. The motor converts this fluid flow into rotational motion, which can then be used to power machinery and equipment.

4. What are the benefits of using a hydraulic pump and motor?

There are several benefits of using a hydraulic pump and motor, including high efficiency, precise control, and low environmental impact. They also have a longer lifespan compared to traditional engines, as they have fewer moving parts and require less maintenance.

5. How do I choose the right hydraulic pump and motor for my 16HP gas engine?

Choosing the right hydraulic pump and motor for your 16HP gas engine will depend on several factors, such as the intended use, flow rate and pressure requirements, and compatibility with other equipment. It is best to consult with a hydraulic specialist or manufacturer to determine the best fit for your specific needs.
