Steering units

Application

Steering units are pumps which are made for accurate dosing of a given volume of working fluid. They are used for steering systems of mobile equipment.

Main characteristics

  • feed rate of the dosed liquid;
  • dosing accuracy;
  • maximum working pressure;
  • the type of working chamber and the material from which it is made.

Principle work of metering pumps

The supply of reagents by metering pumps is controlled by the change in the length of the piston stroke, produced by a micrometric screw or special mechanical dividers, acting to limit the piston stroke.

The number of piston strokes (operating cycles) is taken into account, controlled by adjusting the settings in the pump control circuitry. The metering pumps are preferably equipped with safety valves and devices for bleeding air from the working chamber

Almost all modern models equipped with electronic controllers for control, which allow you to change the flow of the reagent from the pump control panel and adjust the dosing rate according to signals from external control devices.

With all the variety, metering pumps can be divided into two main categories:

  • Plunger and diaphragm (depending on the design of the piston);
  • Mechanical and hydraulic driven pumps.

Main characteristics which you have to pay attention while choosing metering pump:

  • The flow rate of the liquid that is dosed;
  • Maximum working pressure;
  • Dosing accuracy;
  • Working chamber type (depending on whether a diaphragm pump or a plunger pump); 
  • Type of material which was used in manufacturing working chamber
