The effect of piston pumps is the shape of the fluid pushing forward by the piston in the pump cylinder. In this regard, piston pumps operate in the form of pressure or removal of the fluid. These pumps operate horizontally or vertically. Simple effective pumps are manufactured as plunger. The piston cylinder is supplied with the pump plunger and sealing elements, and the piston is included in these sealing elements in a forward motion. The upper side of the pump is equipped with a suction valve at the bottom of the pressure valve. Other than that, the pressure side of the discharge pipe is located on the suction side. At the end of the suction side, there is a suction sleeve or a braided basket to keep the pollution away from the pump. Before the suction hive, a base valve ensures that the suction crown is kept full of fluid.
The distribution of force in the piston pumps is very variable in suction and pressure. In order to avoid this unfavorable situation, to ensure better distribution of forces and to ensure equal volume flow, two, three and more pistons are placed side-by-sides, balancing the forces coming from the Kranka, to provide a homogeneous distribution. In this way, multi-cylinder pumps are used especially for high pressure pumps.
With the connection of the pump, the air boiler is provided with a very long time and the pump's smooth and smooth operation against the sudden pressure rises or unbalanced force distribution is ensured.
Gradual pumps are used to regulate the irregularity of the water flow and the movement of the piston back and forth to a certain extent.
PISTON pumps make use of the pressure of the piston to apply pressure and pump on liquids. If the pump piston has been emptied, the volume is raised and the compression process is carried out by shrinking. The liquid starts to drain with the low pressure or suction valve opening of the piston, which consists of emptying the cylinder volume. The stuffing of the liquid continues until the dead point in the suction period of the piston. With the liquid effect trapped in the volume of the piston's return, it starts pushing from the opening valve to the fluid discharge side. This thrust will continue to the dead point of the piston again. Meanwhile, the Piston meets all friction and counterpressures. After that, a second stroke begins again. The way a simple effective piston pump is seen in the schematic principle picture.

The number of strokes or crankshaft is the rpm rotation. In simple-to-effect piston pumps, the liquid is pressed evenly in each stroke and the same pump power is required in each discharge period.
The number of rotations n depends, the piston stroke s. With increased piston stroke, n rotation count should be decreased. where S. N = 1....... is around 2 m/s, it does not take great values in the linear movement of the piston. Numerical correlation between Piston stroke and rotation count:
S M 1-0.6-0.4 > 0.4
n d/SN 0.7-1.2 1.7-4
D mm > 50 50-150 > 150
