ZM7116C Centrifugal Pumps Characteristics Vocational Trainer Workbench Educational Laboratory Bench Lab Fluid Mechanics Equipment 1. Product Overview 1.1 Product description The horizontal corrosion-resistant chemical pump is a single-stage single-suction (axial suction) cantilever centrifugal pump, which is used to transport liquids that do not contain solid particles and have a corrosive viscosity similar to water. The pump that transports liquid by the centrifugal force generated when the impeller rotates is mainly composed of an impeller, a pump body, a pump shaft, a bearing, a seal ring, and a stuffing box. Centrifugal pumps are turbomachinery used to transport fluids, and can be used to study centrifugal pumps and record typical pump characteristic curves. The experimental device includes a self-priming centrifugal pump, a ball valve on the outlet side, and pressure gauges on the inlet and outlet sides. It is driven by an asynchronous motor. By using a frequency converter, the speed is adjustable. The ball valve is used to adjust the head. In the experiment, the pump's operating characteristics were studied as a function of flow rate and displayed in the characteristic curve. The speed and power of the motor are displayed digitally. The pressure on the inlet and outlet sides is displayed on two pressure gauges. 1.2 Product composition 1. Control panel 2. Hand valve 3. Pressure gauge 4. Speed sensor 5. Centrifugal pump 6.
