  • Precautions For High Temperature Heat Transfer Oil Pumps Operation

    During the first 3-4 hours of high temperature heat-conducting oil pump in operation, turn off the oil pump after heating the equipment to the operating temperature, check the coaxiality of the pump shaft and the motor shaft coupling, and the deviation between the pump shaft and the motor shaft should be controlled within the allowable range The pu...

  • Key Features Of Hydraulic Oil And Application Of Hydraulic Pumps

    Just because the wrong type of hydraulic fluid is used, the hydraulic pump can become inefficient or damaged. How do you know if you are using the correct fluid for your hydraulic pump? The answer to this question depends on several factors, including the type of pump, its maximum operating temperature, its maximum operating pressure, and even the ...

  • Working Characteristics Of Internal Gear Pumps

    Internal Gear Pumps    use internal and external gears. The gear itself is lubricated by a fluid having lubricating properties. The internal design is considered reliable, easy to operate and maintain-because there are only two moving parts. The mechanism only needs one drive gear to work, but two can also be used. The pump will usually contain at ...

  • Internal Gear Pumps: What Are The Limitations?

    The     Internal Gear Pumps   is self-priming and can dry up, although it will improve its oil absorption characteristics if the gear is wet. Gears need to be lubricated by the pumped liquid and should not idle for long periods of time. Some gear pump designs can operate in either direction, so, for example, the same pump can be used to load and un...

  • Learn About Your Vane Pumps Application Technical Information

    The rotor of a vane pump has radial grooves which are located off-center in the housing bore. Blades that fit tightly in the rotor slots slide in and out as the rotor rotates. Centrifugal, hydraulic or push rods help the blades. The pumping action is caused by the expansion and contraction volume contained in the rotor, blades and housing. The blad...

  • Vane Pumps: No Oil? Not Accompanied By The Exit Pressure?

    Almost all causes of failure of the    Vane Pumps    may be caused by the lack of pressure or no pressure at all. The China vane pump manufacturer, supplier & Zhejiang Yongling Hydraulic Machine Co , Ltd . explained:   1. Poor contact between the oil distribution plate and the end surface (fixed surface) of the casing, and there is a large...

  • Double Vane Pumps: Internal Structure And Instructions For Use

    The double vane pump is composed of two pumps with the same displacement or two different displacements. The two pumps share an oil suction port and are connected by an intermediate. There are two oil outlets, which are respectively covered by the front cover. It is separated from the back cover and driven by a core shaft. Although the double vane ...

  • Zhejiang Yongling Hydraulic Machinery: Oil Pumps Failure Causes

    What are the reasons for the failure of the   Oil Pumps  ? How can I resolve these failures? China oil pumps manufacturer & Zhejiang Yongling Hydraulic Machinery Co., Ltd. explained:   1. The oil pumps oil seal wears, the rubber seal of the rubber seal aging unloading sheet ages and changes, loses its elasticity, and loses the sealing and ...
