Operation of a manual hydraulic pump

Have you ever found yourself in a situation where you had to lift a heavy load, but lacked the physical strength to do so? Or perhaps you've witnessed a worker performing seemingly impossible tasks using a small hand tool? Behind these feats lies an ingenious technology: the manual hydraulic pump. In this article, we'll explore how this little machine can transform your physical strength into hydraulic power to perform heavy and complex tasks.

What is a manual hydraulic pump?

As the name suggests, a hydraulic hand pump is a piece of equipment that uses a hydraulic system to produce mechanical energy. Unlike an electric pump, manual pumps do not require electricity to operate. This makes them an ideal solution in environments where there is no electricity.

What is a manual hydraulic pump made of ?

Pompe à main – Sciences de l'Ingénieur

If you have a hydropumpif you're looking at a manual pump, you'll see that it's made up of three main parts: the pump body, the pumping system and the discharge valve.

On the one hand, the pump casing is the external housing that contains the pumping system and the discharge valve.

The pumping system comprises a piston or diaphragm that moves inside the pump to pump hydraulic fluid.

The relief valve also controls the discharge of hydraulic fluid from the pump.

How does a manual hydraulic pump work ?

Pompe hydraulique et moteur, principe et fonctionnement !

The principle of operation of a manual hydraulic pump is fairly simple. It uses a piston or diaphragm to pump hydraulic fluid through a closed circuit.

When you operate the pump handle or lever, you create a force that acts on a piston in the pump body. This force drives the piston backwards, creating a negative pressure inside the pump body.

As the piston moves backwards, it creates a vacuum in the cylinder. Water, liquid or gas is then naturally drawn in due to the pressure difference between the inside and outside of the pump. The liquid is drawn into the cylinder through an inlet valve.

Once the piston is pulled all the way back, the inlet valve closes and the outlet valve opens. When the piston is pushed forward, the liquid is forced out of the pump through the outlet valve.

This means that tools or equipment such as jacks, presses, winches, jacks, tension dividers or bending machines can be driven by the mechanical force produced.

How is oil pressure generated in a hydraulic hand pump using pistons and valves, and what is the function of the reservoir ?

Would you like to know how oil pressure is generated in a hydraulic hand pump using pistons and valves, and the function of the reservoir ?Well, you're doing the right thing !

On the one hand, pistons are moving parts that allow oil to be compressed and propelled through the hydraulic circuit.

Valves are regulating elements that control the flow of oil through the pump. They are designed to prevent the oil from flowing back to maintain a constant pressure in the hydraulic circuit.

The reservoir also serves as a storage tank for hydraulic oil, ensuring a continuous supply of oil to the pump. The tank also helps to maintain the oil temperature at an optimum level. Without a proper reservoir, the hydraulic pump could suffer from overheating and premature wear. This could lead to costly breakdowns.

Now that you understand the crucial role of pistons, valves and reservoir in the operation of a hydraulic pump, you'll be able to optimise the use of your hydraulic equipment and extend its life.

When these elements are in good working order, the hydraulic pump can provide constant, reliable pressure to operate hydraulic equipment safely and efficiently.

The role of hydraulic oil

If you plan to use hydraulic equipment, you need to familiarise yourself with hydraulic oil. To better understand the importance of using the right hydraulic fluid, you need to know the role of hydraulic oil.

Hydraulic oil is a working fluid used to transmit pressure from one point to another in a hydraulic system. It is essential for transmitting hydraulic power in equipment such as cranes, excavators and presses. It is also used in aircraft, motor vehicles and industrial machinery to transmit power to various parts of the system.

Another important role of hydraulic oil is to lubricate the components of the hydraulic system. Metal parts in constant motion, such as pumps, valves and cylinders, are exposed to high pressure and friction. Hydraulic oil provides wear protection by creating a thin layer of lubrication between the moving parts.

Hydraulic oil can also play a role in heat dissipation. Hydraulic systems often generate heat due to friction and power losses. Hydraulic oil absorbs this heat and transports it to the reservoir, where it is dissipated into the air or cooling water.

What is the role of the oil filter in a manual hydraulic pump?

If you are using awhen it comes to manual hydraulic pumps, you know how important clean hydraulic oil is for the efficient operation and long life of your equipment. However, it's not enough, what is the role of the oil filter in a manual hydraulic pump? ? ?

Comprising a filter element and a housing, the oil filter is generally located in the fluid intake circuit, just before the hydraulic pump.

The filter element can be a paper filter, a cloth filter or a metal filter. The housing is designed to protect the filter element and allow hydraulic fluid to flow through the filter.

The oil filter is actually designed to remove impurities and foreign particles from the hydraulic fluid. In doing so, it prevents them from accumulating and spreading through the system.

The accumulation of foreign particles in hydraulic oil can cause damage to the hydraulic system, such as leaks, premature wear of components, reduced performance and even total failure. An effective oil filter removes foreign particles from hydraulic fluid, extending the life of your equipment and improving its performance.

What are the advantages of a manual hydraulic pump ?

The manual pump has a number of advantages that justify the love industry has for it.

Firstly, it is highly reliable and resilient, as it does not depend on electricity or other external energy sources.

Secondly, it's easy to use and maintain, because it doesn't require complex moving parts or delicate electronics.

Finally, it is highly versatile, as it can be used in many different applications, from construction to agriculture to the oil and gas industry.
