hydraulic piston pump working principle

Pistons are durable and relatively simple devices. A basic plunger pump consists of a piston, a chamber, and two valves. The pump works by driving the piston down into the chamber, compressing the medium inside. In a hand pump, this is usually air. Once the pressure of the air exceeds the pressure of the outlet valve spring, the compressed medium will pass through the open outlet valve. When the piston is pulled back, it opens the inlet valve and closes the outlet valve, thereby using suction to draw in new medium for compression.

Although somewhat expensive, pistons are one of the most efficient types of pumps. Because they have pressure ratings up to 10,000 psi, they provide an excellent solution for many high pressure hydraulic oil pump applications. Although there are many types of pistons, because the hydraulic piston pump has the most advantages among all types of piston pumps, it stands out and becomes the most widely used piston pump. The hydraulic piston pump working principle is mainly that the hydraulic piston pump is powered by the hydraulic oil tank that supplies oil with air pressure. Therefore, after each startup of the machine, the hydraulic oil tank must reach the operating air pressure before operating the machine. The straight shaft swash plate piston pump is divided into two types: pressure oil supply type and self-priming oil type. Most of the pressure oil supply type hydraulic pumps use a fuel tank with air pressure, and some hydraulic pumps themselves have an oil charge sub-pump to provide pressure oil to the oil inlet of the hydraulic pump. The self-priming hydraulic pump has a strong self-priming ability and does not require external oil supply. There are many suppliers of plunger pumps, but there are only a handful of reliable manufacturers, and the Elephant brand is one of them. Here we show you the products of the Elephant Fluid Power brand. Such as K21E160HD1D/10W-VZI38800-S hydraulic piston pump, they use a bent shaft design. The swashplate design also features a variable displacement pump with an axial piston rotary group for hydrostatic drives in open circuits. If you look closely, its flow is proportional to drive speed and displacement. By adjusting different swashplate angles, the flow can be infinitely changed. The product is equipped with 2 drains. Has excellent suction performance. Elephants use technologies that make them quieter during use and have a longer lifespan and faster operating response. In-line drive is suitable for adding gear pumps and axial piston pumps of the same size, i.e. 100% in-line drive.
