Shape and installation dimensions

The dual pumps are composed of two single pumps, and each single pump still maintains its displacement.The driving power is the sum of two single pumps, and the pressure and speed are the same as those of single pumps.

          YB1 type vane pump is a medium-pressure double-acting quantitative pump, suitable for medium and low-pressure systems of metal cutting machines and other machinery.This pump is generally forward and can be installed in reverse as neededEssence

YB1 dual-coupled quantitative vane pumpworking principle

       YB1 dual-coupled quantitative vane pump is a medium and low-pressure quantitative double-acting vane pump.The YB1 dual-coupled quantitative vane pump has a rated pressure of 63kg.The displacement is 4~100ml/r, and users can choose according to their needs.It is an energy conversion device that converts the mechanical energy output by the motor into hydraulic energy, and is used as a hydraulic energy that provides a certain flow pressure in the hydraulic system.The pump has a compact structure, small size, uniform flow, small pressure pulsation, low noise, high efficiency, reliable performance and reasonable price.YB1 dual-coupled quantitative vane pump isYBThe improved design, the appearance installation connection sizes are the same as those of YB type, and are the updated product of my country's medium-pressure vane pumps, and the appearance installation connection sizes are the same as those of YB type.The double pump stator, rotor, blade and flow distribution plate are fastened into a assembly with screws, which is convenient for assembly and maintenance, and has an axial gap compensation structure.

       YB1 quantitative dual-blade pumpIt is widely used in various medium and low pressure hydraulic systems, such as various metal cutting machine tools, hydraulic presses, plastic machinery and various engineering machinery.Dual vane pumps are generally forward-rotating and can be installed in reverse as needed.

Precautions for using YB1 dual-dosing vane pump

1. Double -linked quantitative blade pumpRadial and axial forces are not allowed to be directly subjected to the pump shaft to avoid abnormal damage to the oil pump.
2. During installation, the hole and the surface of the connecting shaft must be carefully wiped to reduce the vibration caused byDual vane pumpThe surface of the shaft end is slightly worn, so that the mating shaft diameter dimensional accuracy is maintained for a long time.
3. Pay attention to distinguishing between oil inlet and oil outlet.Usually, the oil inlet is large and the oil outlet is small. Do not reverse it. Only when the double-coupled quantitative vane pump is verified to be in line with the direction of the sign arrow can the motor be started until the hydraulic vane pump is discharged normally before it is officially started.
4. Dual pumpThe oil suction height generally does not exceed 500mm, and the pump suction inlet pressure is between 0.02 and 0.025MPa. The larger the displacement of the hydraulic vane pump, the higher the suction pressure is required.
5. Leaf pumpThe connection between the entire oil suction pipe and accessories from the oil inlet, pipe joints and pipe joints up to the oil level of the oil tank must be strictly sealed, and no air leakage should be leaked in any part, otherwise a large amount of foam will be generated in the oil tank, and air sucking in will also causebladeCavitation occurs in the oil pump, causingbladeOil pump noise, damage and vibration of the hydraulic system.
6. In order to prevent the quantitative vane pump from inhaling debris and reducing wear, the oil inlet of the dual vane pump should be equipped with a 100-180um oil filter, and its filtration capacity should not be less than three times the flow of the dual pump. It is also recommended to install an oil filter with an accuracy of 30-55um at the oil outlet of the oil drainage pipeline to ensure the cleanliness of the oil, improve the stability of the hydraulic system and the working life of the hydraulic components.
7. To ensure the performance of the dual-blade pump and extend the service life, the hydraulic system should use anti-wear hydraulic oil. It is recommended to use N46 anti-wearHydraulic oil, the long-term working oil temperature should be within the range of 10℃ to 60℃.The oil tank design should be closed, and the oil filter needs to be cleaned regularly and the quality of the oil is checked, and the working oil is replaced according to actual conditions.
