Hydraulic Pumps Explained
Hydraulic pumps are very simple and they have many applications. Their basic design is a piston in a cylinder that puts a force on an incompressible liquid (often oil), and the force is transmitted to another piston which will do something useful for you. The force is usually multiplied during the process, and so the second piston can achieve much more than the first. To create force multiplication, the relative size of the pistons is increased.
The oil needs to be free from bubbles because if a piston is used when bubbles are present, a lot of the force is wasted compressing them rather than driving the second piston which is definitely not an efficient way to go about things. Most pump failures are because of oil contamination of one kind or another. The oil reservoirs should be made from aluminium or stainless steel to avoid corrosion and reduce the chance of any oil contamination.
The pipe containing the oil can be varied lengths and shapes in a hydraulic pump which is very useful because they can be used in almost any system design. The pipes can also be branched so that the master piston drives two or more slaves.
You may not even know it but you probably own a hydraulic pump. Vehicles use them for the braking system. When you push down on the brake pedal it applies pressure to two master cylinder pistons which each drive two slave pistons (there’s one at each wheel). These then press the brake pads against the brake rotor to stop the car. The thought behind two cylinders each driving a pair of cylinders as opposed to one cylinder driving four is in case there is a fault with a master cylinder - in this case if you only have a single master cylinder, you cannot stop the car because all of your brake pads cannot work properly.
Some hydraulic pumps are manual and some are powered by compressed air, electricity or petrol. Manual hydraulic pumps are great because they have portability because they don’t need an additional power supply. They are perfect for occasional tasks but they do lack the power and speed of powered pumps. They also require physical effort to operate.
Pneumatic and electric pumps are both good when the required power source is nearby. They will acheive more in a quicker time than a manual hydraulic pump but the downside is the price and the fact that they must be powered by electricity or air and so the supply must be near to hand.
Petrol pumps are perfect for cases where a manual pump is not powerful enough and where the constraints of an electric or pneumatic pump don’t allow for use in remote places.
Hydraulic pumps have many uses but if you find that you need to purchase one yourself, make sure that you do your background research and get the right one.
