Stable Performance Hydraulic Equipment Plunger Pump For Switch Machine

Plunger Pump for Switch Machine

Model: ZT-7YB2.1

Performance parameters

① Working medium: YH-10# aviation hydraulic oil;

② Displacement: 2.1ml/r;

③ Rated pressure: 12MPa; maximum pressure: 20MPa;

④ Rated speed: 960r/min; maximum speed: 1400r/min; minimum speed: 60r/min;

⑤ The minimum suction pressure is no more than -0.05 MPa;

⑥ When the speed is 990r/min and the load is zero, the torque is less than 0.8Nm and the output flow rate is greater than 2.05L/min;

⑦ When the speed is 990r/min and the load is 11Mpa, the input torque is less than 4.4Nm;

⑧ When the speed is 960r/min and the load is 12Mpa, the output flow rate is over 1.85L/min;

⑨ When the speed is 960r/min and the load is 20Mpa, the output flow rate is over 1.70L/min;

⑩ When the speed is 100r/min, the output pressure of the oil pump should be greater than 18MPa, and the swing amplitude is not more than 2MPa;

The above performance should meet the two-way requirements;

⑪ Service life: Under the condition of speed 960r/min, outlet pressure 12MPa, reversing every 15min, after 2400 hours of continuous operation, the set pressure should not be lower than 95% of the calibration value and the volumetric efficiency should not be less than 88%.

Features and application:

Features: high reliability and long life; stable performance;

Application: for EHC switch machine for high-speed railway.
