Before we get into high pressure pumps, it may help to take a step back and discuss water pumps on a more fundamental level. At their core, water pumps are designed to move water from one point to another. As such, the core metric for measuring water pumps is the flow rate. Flow rate in the US is typically measured in gallons per minute (GPM). Flow rate here in China is always measured in cubic meter per hour.
A high pressure pump allows the machine to work just as we have our hearts to pump blood through our bodies. It is the pump that produces a force so that the water creates a flow. It’s built to last for many years and to keep producing high amounts of pressure.
If the high pressure pump is classified according to the medium, it can be divided into: high pressure piston pump, high pressure reciprocating pump, high pressure electric pressure test pump, high pressure cleaning pump.
We’re going to look specifically at the high pressure axial piston pump. Axial piston pump is a kind of reciprocating pump. Axial piston pump is generally composed of main parts such as cylinder block, valve plate, piston and swash plate. There are multiple pistons in the cylinder, the pistons are arranged axially, that is, the centerline of the pistons is parallel to the axis of the drive shaft, so it is called an axial piston pump. But it is different from the radial plunger pump because its piston not only reciprocates in the pump cylinder, but also the piston and the pump cylinder rotate relative to the swash plate. The piston contacts the swash plate with a spherical end. There are high and low pressure moon-shaped grooves on the valve plate, which are separated from each other by a partition wall to ensure a certain degree of sealing. They are respectively connected with the water inlet and water outlet of the pump. There is an inclination angle between the axis of the swash plate and the axis of the cylinder.
