TOKIMEC type SQP421, SQP431, SQP432 series triple vane pump (I)
1. Product Overview
TOKIMEC type SQP421 series triple vane pump from He Hydraulics: This series of vane oil pumps are efficient and stable, and are suitable for environments with complex oil circuits and large oil pressure differences.
TOKIMEC type SQP431 series triple vane pump: This series of vane pumps is optimized on the basis of SQP421, with higher performance and wider application range. Its compact structure and reasonable design can meet the needs of various complex working conditions.
TOKIMEC SQP432 series triple vane pump: This series of vane pumps has excellent performance and reliability. Its unique vane design and optimized oil circuit layout enable it to maintain stable output under various harsh working conditions.
2. Product Features
Triple pump head design: three pump heads are connected in series and only require one motor to drive, reducing energy consumption and cost.
Independent oil inlet, oil outlet and pressure regulating valve: each pump head has an independent oil inlet, oil outlet and pressure regulating valve, which can achieve precise control of different oil circuits.
High efficiency and energy saving: The advanced blade design and oil circuit layout reduce energy consumption and noise and improve the efficiency of the pump.
Stable and reliable: The use of high-quality materials and precision manufacturing technology ensures the stability and reliability of the pump.
3. Notes
Pump direction: The vane pump has a specified direction and does not allow reversal. Because the rotor blade groove is tilted, the blade has a chamfer, the bottom of the blade is connected to the oil discharge cavity, and the throttle groove and suction and discharge ports on the oil distribution plate are designed according to the established direction.
Assembly requirements: The oil distribution plate and the stator should be correctly positioned with the positioning pins, and the blades, rotors and oil distribution plate should not be installed upside down. The suction area on the inner surface of the stator is most susceptible to wear. If necessary, it can be turned over to make the original suction area become the discharge area and continue to be used.
Disassembly and assembly requirements: Pay attention to the cleanliness of the working surface during disassembly and assembly, and the oil should be well filtered during work.
Gap adjustment: The gap between the blades in the blade groove should be moderate. If it is too large, leakage will increase. If it is too small, the blades cannot expand and contract freely, which will cause malfunction. The axial clearance of the vane pump also has a great influence on the efficiency of the pump and needs to be adjusted according to the type of pump.
Oil temperature and viscosity: The temperature and viscosity of the oil have a great influence on the performance of the pump. Generally, it should not exceed 55°C, and the viscosity should be between 17 and 37 mm²/s. If the viscosity is too high, it will be difficult to absorb the oil, and if the viscosity is too low, leakage will be serious.
4. Application fields
