Third, the basic configuration of the device

The experimental device is composed of control screen, experimental table, cross -current power supply, measuring instrument component, load component, motor unit, experimental hanging, experimental wires and accessories.

(1) AC power supply part

Provide a three -phase 0-450V adjustable AC power supply, and at the same time, a single -phase 0 to 250V -adjustable AC power supply can be obt--ned. It is equipped with a three -same -the same axis linked auto -coupling pressure dealer (specification of 6kva and 0 to 450V). The output of adjustable AC power supply has a short -circuit protection device, which can be protected when phase and line over -current and direct short circuit can be protected. The power supply of the control screen is controlled by the start -stop buttons, and at the same time, it has the function of leakage lighting, overvoltage protection, phase order indication, and lack of phase instructions; with three pointer AC voltage tables, through switching switches, the voltage of three -phase grid voltage can be indicated. And three -phase pressure regulation voltage.

1. Experimental purpose:

The chemical concrete agent is put into the concrete and precipitated test by being put into a chemical concrete in some water samples (giving water and dr--nage). Due to the different water quality of the water -like water, the concrete effect is also different. The requirements of this experiment have achieved the following goals:

1. Learn to obt--n the process conditions of the concrete, that is, the basic method of ** pH value, ** concrete and ** investment adding dosage.

2. Deepen the understanding of the precipitation of concrete and oblique tube through experiments.

2. Experimental principle:

The colloidal particles in the water are m--nly negative clay particles. The static exclusion force, the brown movement of the glue, and the hydration of the surface of the glue make the rubber particles have decentralized stability, and the three of them are affected by electrostatic exclusion. Therefore, colloidal particles cannot be removed by natural precipitation. Adding concrete to the water can provide a large amount of positive ions, the diffusion layer of the compressed rubber ball, reduce the potential of the pyrine, and reduce the exclusion of static electricity. At this time, the changes in the stability of the Brown Sports into unstable factor are also conducive to the adsorption condensation of glue.

In the water of the concrete, the colloidal particles gathered together after being stabilized, and gradually became larger. At this time, the size of the water flow speed shaved plays a m--n role.
