  • What Is The Hydraulic Pumps -Down Phenomenon?

    The suction of the hydraulic pump mainly refers to the mixing of air into the oil sucked by the hydraulic pump, which not only easily causes the phenomenon of "cavitation" and increases noise, but also affects the volumetric efficiency of the hydraulic pump and easily deteriorates the hydraulic oil. Not allowed in hydraulic systems. The volumetric ...

  • Introduction Of The Main Application Of Internal Gear Pumps

    Internal gear pumps are versatile and have an effective working viscosity range from 1 cP to 1,000,000 cP. They are commonly used for thin liquids such as water, solvents and fuel oils, but are good at pumping thick liquids such as asphalt, chocolate and adhesives. Internal gear pumps also have a wide operating temperature range (up to 400 ° C), ma...

  • Internal Combustion Engine & Oil Pumps In High Performance Engine

    An oil pump in an internal combustion engine circulates the engine oil under pressure to the engine's rotating bearings, sliding pistons, and camshafts. This lubricates the bearings, allows the use of large-capacity fluid bearings, and also helps cool the engine.   In addition to the main purpose of lubrication, pressurized oil is also increas...

  • Definition Of Displacement And Flow Rate Of Hydraulic Pumps

    Displacement refers to the volume of liquid discharged (or input) obtained by the change of the geometric dimensions of the sealed cavity every revolution of the hydraulic pump. The common unit is ml / r (ml / rev). The displacement can be changed into a variable pump (or variable motor) by adjusting, and the displacement cannot be changed into a f...

  • How To Prevent And Cure: Hydraulic Pumps Oil Temperature Problem

    Engineering machinery hydraulic pump oil working temperature is generally better in the range of 30 degrees to 80 degrees, too high oil temperature will have a series of adverse effects on the system, such as reduced viscosity, increased leakage, volumetric efficiency decreased, resulting in hydraulic velocity Unstable, will cause gaps between moti...

  • Why Choose An Internal Gear Pumps?

    Many industrial manufacturing plants require the use of hazardous chemicals in their operations. Materials such as strong acids, resins, polymers, solvents, and caustic are common in industrial applications.     One of the main problems caused by the use of these hazardous chemicals is how to handle materials safely. This process can be c...
