Load Sensing systems are used to maintain constant speed of hydraulic actuators even with load variation on them.
The main advantages of using this technology range from reducing energy consumption to increasing the performance of the machines where it is used.
What is the Load Sensing system?
Load Sensing or Demand Flow. In other words: it is a hydraulic system made up of a variable displacement pump that creates the necessary pressure and/or flow according to your needs.
How does a hydrostatic pump work?
The basis of the operation of these pumps is based on hydrostatics, where a variation in volume generates a variation in pressure. Hydraulic pumps consist of cylinders that aspirate liquid through blades that, when rotating, generate a suction current.
How does a variable displacement piston pump work?
The operation of variable displacement piston pumps is based on a pressure compensating control. When the pressure exceeds 20 MPa (200 bar), the flow rate starts to decrease (cut-off point). Decreasing the flow decreases the input power.
How does a variable displacement type vane pump work?
The operation of variable displacement vane pumps roughly consists of a pressure compensating principle, through which the pumping O-ring maintains its displaced position by means of an adjustable spring.
What is a variable speed pump?
This is a system in which the electric motor of the pump varies its speed or revolutions per minute through electronic control. Going and stopping would consume a lot more gas, the engine would die, and all the traffic would be jostling.
What pump to use for the pool?
CENTRIFUGAL PUMPS: More common in large pools, mainly in pools for private use. BLOWER PUMPS: Common in spa or wellness spaces, as well as in swimming pools with areas dedicated to relaxation through air and water.

How does a hydrostatic pump work?
A hydrostatic pump is a machine that provides power for a hydraulic motor. This is accomplished by taking a liquid and creating flow, which will lead to pressure. Once the liquid is pressurized, it will move with more force, creating mechanical energy.
How does hydrostatics work?
What is hydrostatic pressure The fluid generates pressure on the bottom, the sides of the container and on the surface of the object introduced into it. Said hydrostatic pressure, with the fluid in a state of rest, causes a force perpendicular to the walls of the container or to the surface of the object.
What is a variable air volume system?
In contrast, a Variable Air Volume (VAV) System delivers primary air at a constant temperature and varies the flow or volume of air to maintain the required space temperature under load conditions.
What are variable air volume boxes?
Variable air volume boxes modulate the airflow supplied to each space using an actuator and controller. There are various types of VAV boxes but all within two classifications:
What is a constant volume system?
Another constant volume system design is an air handling unit that has a fan and cooling coil to send primary cool air to all zones to meet the demand of the zones that need to be cooled.
