The energy-saving effect of the energy-saving water injection pump is remarkable. The injection can be realized without introducing a high-power source using only a small power motor with a (1. 1, {text {kW}}) power to drive the mechanical directional control valve and a motor-driven hydraulic pump with a power of (1 1, {text {kW}}).
What are the structural parameters of the energy-saving water injection pump?
The structural parameters of the energy-saving water injection pump were determined. The finite element simulation of the piston cylinder and the plunger cylinder was performed, which shows that the structural strength meets the requirements. The hydraulic system dynamic simulation shows that the output pressure meets the water injection pressure.
Can a water injection device meet the injection pressure and power consumption requirements?
The output pressure and power consumption were recorded every day. The records are presented in Table 3. The data reveal that the device can meet the injection pressure and everyday water injection requirements of the two high-pressure wells and that the device is qualified for the injection task.
How a water injection pump works?
The water smoothly flows in the plunger, the pressure change is not steep, and the work condition is stable. After completing the design of the energy-saving water injection pump, the parts were processed and finally assembled according to the drawings, as shown in Fig. 14.
