  • Analysis And Prevention Of Vane Pumps Cavitation

    Cavitation is a widespread phenomenon in vane pump products. It damages vane pumps very seriously, which seriously affects the service life of water pumps, causing social waste that cannot be underestimated and safety accidents. Therefore, it is necessary to study the cavitation of the vane pump to prevent the occurrence of cavitation, or to minimi...

  • Oil Pumps -How To Choose The Heat Transfer Oil Pump?

    Based on what selection of heat transfer oil pump? Should be based on the process flow, water supply and drainage requirements, from five aspects to consider, namely the liquid delivery volume, device head, liquid properties, pipeline layout and operating conditions. 1. Liquid properties, including the name of the liquid medium, physical properties...

  • 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...

  • Internal Gear Pumps: Common Faults And Maintenance Methods

    Common failures of     Internal Gear Pumps    : the pump cannot be oiled, the output flow is insufficient, and the pressure cannot be increased. China internal gear pump manufacturer, supplier & Zhejiang Yongling Hydraulic Machinery Co., Ltd. describes the following troubleshooting methods for gear pumps of this kind: First, check the external ...
