Background
The constant flow injection pump is a capacity pump, is mainly applied to the distribution or the transportation of fluid, and is widely applied to the industries of food, chemical industry and the like. When the constant flow injection pump is used for transferring liquid, the injector performs reciprocating pumping and pushing movement, and meanwhile, the reversing valve is matched with the injector in a reversing way to complete the transfer of the liquid.
The switching valve of the current constant flow pump is operated by respectively driving two reversing valve cores through 2 stepping motors.
The control mode of the original constant flow injection pump reversing valve is to switch by the movement of the stepping motor according to a preset program. The cost is high (two sets of control systems and motors), the reversing valve cannot be too close due to the shape problem, otherwise, the pipeline joints can interfere with each other, and the whole size of the pump body is influenced to be larger and heavier. The operation installation is inconvenient, has two inlet and two liquid outlets, needs to insert four pipelines and connects. To achieve the constant flow effect, an external tee joint is connected to combine the liquid outlet into an outlet. The pipeline is too long, and the probability of stable operation under the influence of external factors is too high. There is no structure to assist in stabilization, and there is no buffering function when the liquid delivery flow fluctuates.
