The invention provides an optical rod
kinetic energy chemical feeding device. An inlet pipeline of a chemical feeding pump is connected with a chemical feeding
barrel, the inlet of the chemical feeding pump is provided with a one-way valve A, an outlet pipeline of the chemical feeding pump is connected to a pressure regulating valve, a one-way valve B is arranged at an outlet of the chemical feeding pump, the back side of the one-way valve B is provided with a pressure gauge A, an outlet pipeline of the pressure adjusting valve is connected to a well pipeline, the pressure gauge B is arrangedon the well pipeline, a one-way valve C, a one-way valve D, a discharging valve and a switching valve are sequentially arranged at the back side of an outlet of the pressure adjusting valve, and a
reflux inlet pipeline of the pressure adjusting valve is connected to the top of a liquid lever meter. The optical rod
kinetic energy chemical feeding device has the advantages that the
kinetic energy ofan oil pumping
machine is fully utilized to serve as
motive power of the chemical feeding pump, addition of extra
power equipment is not required, the device is easy to maintain, the organic cooperation between the device and a
wellhead does not influence other operation of the
wellhead, and the effect of reducing the chemical feeding cost can be achieved; the chemical feeding amount can be adjusted, and accurate
medicine addition can be achieved without stopping operation of the well; the device is small in size, easy to install, less in maintenance demand and attractive in appearance.
