Functional scope

R45Gear pumps are mainly used for conveying and boosting media in hydraulic systems

Medium conveying can stably transport various viscous fluids such as hydraulic oil, lubricating oil, mineral oil, etc., realizing the circulation or supply of medium in the system

The pressure is established through the volume change generated by gear meshing, providing stable working pressure for the hydraulic system and driving the actuator components (such as oil cylinders and motors) to act

Although gear pumps are quantitative pumps, flow regulation can be indirectly achieved by cooperating with relief valves and variable mechanisms to regulate system flow

System oil replenishment can be used as an auxiliary pump in large hydraulic systems to replenish oil and maintain stable system pressure

Temperature and pressure range

medium temperature

The normal operating temperature is-20℃to+100℃Short term affordability120℃High temperature (duration not exceeding)30Minutes)

ambient temperature

Adapting to environmental temperature-30℃to+60℃If the ambient temperature is too high, heat dissipation measures need to be taken

temperature effect

When the temperature of the medium is lower than-10℃It is recommended to preheat to avoid difficulty in starting due to increased viscosity; temperature exceeds80℃Pay attention to the aging of the sealing components and shorten the maintenance cycle appropriately

pressure range

The recommended continuous work pressure for work pressure is160-250 barDepending on the model and displacement, small displacement models can withstand higher pressure

Pressure fluctuations allow the system pressure to fluctuate within±10%Fluctuations within the range may affect the service life and stability of the pump beyond this range

When the system is unloaded, the outlet pressure of the pump should decrease to5 barBelow, to reduce no-load losses and heat generation

Medium requirements during use

R45Gear pumps have strong adaptability to media, but in order to ensure their performance and lifespan, the following requirements must be met

Priority should be given to using mineral oil-based hydraulic oil (such asISO VG 32、46、68It can also be used to synthesize hydraulic oil, lubricating oil, diesel, etc., but compatibility needs to be confirmed with the manufacturer in advance

The normal operating viscosity range is10-400 cStThe optimal viscosity range is30-100 cStThe viscosity is lower than10 cStAt this time, it may lead to poor lubrication; above400 cStWhen using, it is necessary to reduce the speed

The cleanliness of the medium should reachISO 4406 18/16/13Grade（NAS 8Level above, it is recommended to install filtering accuracy in the system≥10μmFilter to prevent impurities from wearing gears and bearings

The water content of the medium needs to be≤0.1%Excessive moisture can easily cause parts to rust and oil emulsion, affecting the normal operation of the pump

And precision

flow characteristics

theoretical flow

The calculation formula isQ=V×n（QFor traffic, unitL/min；VFor displacement, unitcm³/rev；nFor rotational speed, unitrpm）For exampleR45/10The model is1500 rpmThe theoretical flow rate is15 L/min

The actual flow rate is affected by factors such as pressure, viscosity, and rotational speed, and is slightly lower than the theoretical flow rate. At rated pressure250 barViscosity40 cStAt that time, the actual flow rate was approximately equal to the theoretical flow rate95%-98%

Flow stability under constant speed and pressure, flow fluctuation≤±2%Ensure smooth operation of the system

precision metric

Accuracy of volumetric efficiency under rated operating conditions, deviation of volumetric efficiency≤±3%Ensure the accuracy of traffic output

When used in conjunction with the system relief valve, the pressure control accuracy can reach±5 barMeet the requirements of precision hydraulic systems

Viscosity and headInfluence of viscosity

The influence of viscosity on flow rate

When the viscosity increases, the internal leakage of the pump decreases and the volumetric efficiency improves, but the flow resistance increases, requiring more power consumption; When viscosity decreases, internal leakage increases, volumetric efficiency decreases, but power consumption decreases

The influence of viscosity on starting performance: When the temperature is low and the viscosity is high, the starting torque increases. It is necessary to ensure that the driving motor has sufficient starting power to avoid motor overload

Head characteristics

The head (i.e. pressure head) of a gear pump is related to pressure, and the calculation formula isH=P/(ρ×g)（HFor head, unitm；PFor pressure, unitPa；ρDensity of the medium, unitkg/m³；gFor gravity acceleration,9.8 m/s²）. Using hydraulic oil (density)850 kg/m³）For example, when the pressure is250 bar（25×10 ⁶ Pa）When, the lift is about25×10 ⁶/ (850×9.8)≈2980 m, indicating that it has strong medium enhancement ability

structural advantage

Double gear meshing design: using high-precision involute gears, with small meshing clearance, less internal leakage, and improved volumetric efficiency

Shaft sleeve support structure: The gear shaft is supported by a wear-resistant shaft sleeve, which is made of bronze or alloy material and has good lubrication and wear resistance, extending the service life of the pump

Integrated design: high integration of pump body, gears, shaft sleeves and other components, compact structure, small installation space, suitable for narrow equipment environments

Bidirectional rotation function: By changing the driving direction, the import and export directions can be switched, increasing the flexibility of use

performance characteristics

High reliability: using high-quality materials and precision machining processes, with long working hours,MTBF(Average time)≥5000hour

Low noise operation: Smooth gear meshing, shock-absorbing design of pump body, operating noise≤75 dB(In)1500 rpmUnder working conditions, it meets industrial noise standards

Strong anti pollution ability: The internal flow channel design is reasonable, insensitive to small impurities in the medium, and reduces faults caused by pollution

Easy maintenance: adopting modular design, simple disassembly and assembly, easy replacement of vulnerable parts (such as seals and shaft sleeves), reducing maintenance costs

Application Fields and Scenarios

Power equipment: used for lubrication systems of steam turbines and generators, delivering lubricating oil to various friction parts

Installation method

R45The installation of gear pumps should follow the following specifications to ensure their normal operation

Installation location

Suggest horizontal installation, with the pump shaft centerline parallel to the ground; If installed vertically, ensure that the motor is above to avoid bearing force on the motor shaft when the pump body is filled with medium

fixation method

Fixed to a rigid foundation with bolts through the installation holes at the bottom of the pump body, the foundation needs to be flat to avoid vibration. The tightening torque of the installation bolts should comply with the manufacturer's regulations to prevent deformation of the pump body

Import and export pipelines

The diameter of the inlet pipe should not be smaller than the inlet diameter of the pump to avoid excessive oil suction resistance; The return pipe should be inserted below the oil tank level to prevent air from entering. The pipeline connection should be sealed reliably and leak free

Drive connection

Using an elastic coupling to connect the pump and motor to ensure coaxiality error≤O.1 mmAngle deviation≤1°To avoid vibration and bearing damage caused by different axes

Exhaust operation

After installation, it is necessary to exhaust the pump and pipeline by opening the exhaust valve of the pump or loosening the outlet pipeline joint until there are no bubbles in the discharged medium

Precautions

to ensureR45The safe and stable operation of gear pumps requires the following precautions during use

Pre-start inspection

Check if the motor direction is correct (consistent with the arrow direction on the pump body); Check if the liquid level of the medium is sufficient to avoid idling; Check if the inlet and outlet valves are open to ensure smooth oil flow

Monitoring during operation

Regularly monitor the outlet pressure, flow rate, temperature, and noise of the pump. If abnormal pressure increases, significant flow rate decreases, or temperature exceeds100℃If the noise suddenly increases, the machine should be stopped immediately for inspection

maintenance

Maintain according to the manufacturer's recommended cycle, usually every operation2000Replace hydraulic oil and filters every hour; Check whether the sealing components are aging or leaking, and replace them in a timely manner; Clean the impurities inside the pump body and keep the flow channel unobstructed.

Avoid overload

It is strictly prohibited to operate the pump for a long time under conditions exceeding the rated pressure and speed, in order to prevent overheating of the pump body and worsening of component wear

Media replacement

If different types of media need to be replaced, the pump and pipeline should be thoroughly cleaned to avoid chemical reactions caused by mixing different media

Winter protection

In low-temperature environments, it is necessary to preheat the medium or use low-temperature hydraulic oil before starting to prevent difficulty in starting or damage to the pump body due to increased viscosity
