Application field of motor pump group
Oil pump selection
1, to determine whether the use of variable vane pump pressure pulsation is small, high volumetric efficiency, flow to follow the pressure change;
2. Determine the pressure, flow, noise, and temperature rise. Determine the pressure and flow parameters of the oil pump according to the power and speed of the system, and consider the noise and temperature rise requirements;
3. Check the installation size to determine the connection mode of the oil pump and the motor, and check the installation size of the oil pump:
4, determine the color appearance of black, green, silver, phosphating and other colors to choose from, indicate the color requirements
5. Special requirements indicate the special requirements for oil pumps and their accessories, such as all copper;
6. Order code Order code = parameter code/installation method/color/special requirements;
Example: 91010504/Spline/Black/All Copper
Notes on the use of oil pump
※ installation
The concentricity of the pump and motor installation shaft is controlled within 0.1mm, and the angle error is less than 0.2 degrees;
※ Piping
Oil suction piping: for the self-priming vane pump, the distance between the oil suction port and the liquid surface is less than 1 m;
Oil drain pipe: the back pressure of the oil drain shall not exceed 0.5bar, and the length shall not exceed 1 m;
※ exhaust
When it is put into use for the first time, the motor should be started repeatedly under no pressure to remove the air in the oil and suction.
Precautions for the use of hydraulic oil
1. Selection of hydraulic oil
The recommend below 70bar uses the viscosity at 40 ℃ 30-50cst(ISOVG-32) hydraulic oil above 70bar recommend uses the viscosity at 40 ℃ 50-70cst(ISOVG-68) hydraulic oil
2. Oil temperature range
In order to ensure long-term reliable operation of the system, the working oil temperature is controlled at 15-60 ℃
3. Oil cleanliness
Always install a suitable filter unit in the equipment system, and regularly replace the cleaning filter element.
4. Oil replacement cycle
Regular oil change method: the time for the equipment to change hydraulic oil for the first time is half a year, and then once a year. Visual oil change method: when the oil turns black or Milky White, the oil sampling and testing method should be replaced in time: regular oil sampling and testing should be carried out to determine whether its performance index meets the standard. If it fails to meet the standard, it should be replaced immediately. It is suitable for key equipment and large-scale equipment.
Performance parameter test environment
1. Hydraulic oil ISOVG-32, motor 4P
2. Temperature rise standard: room temperature 30 ℃,60L oil tank, oil temperature rise during continuous operation
