1. Equipment introduction
1.1 Overview
This product provides controlled water flow for various laboratory experiment modules (available separately). The main body of the workbench forms a reservoir with a submersible pump. When the water level reaches a suitable level, it can meet the circulating water requirements for the experiment without the need for external water supply.
Two manual control valves regulate the water flow from the pump, and one of the manual valves is used as a relief valve. This can keep the circulating water path open and the water pump will not be overloaded when the experimental pipeline is closed due to accident. The electrical box on the side of the bench includes pump switches, circuit protection, power supply knowledge and digital flow display.
Four allow users to move around the classroom, and all four wheels have foot locks to hold the casters in place.
The liquid level viewing port on the underside of the workbench allows the user to check the water level within the tank.
The top of the workbench provides a work surface. Matching fluid experiment modules can be placed in this position, and larger experiments are usually placed next to the workbench. The edge at the top effectively prevents water from spilling out. A small groove on the top collects water discharged from some experiments within the hydrodynamic range.
The test bench consists of four parts: test cycle system, real-time system, electrical control system and bench. The centrifugal pumps selected for the test pump have rated flows of 40L/min and 80L/min respectively. This pump has the characteristics of compact structure, smooth operation, small flow and pressure pulsations, and low noise. It can provide sufficient and reliable power source for the test system. In conjunction with electrical frequency conversion control, stepless speed regulation within the rated flow range can be achieved. The flow meter in the flow meter system uses a precision intensity mass flow meter with an accuracy of 0.15% to meet the system's requirements for flow accuracy and range. In order to ensure accurate test accuracy, the system is designed with two test flow sections. The measurement range of flow section 1: 1 ~ 40L/min, and the measurement range of flow section 2: 40 ~ 80L/min.
