How to operate the inverter water cooling system?

1. temperature control: the inlet temperature of cooling water is also the water temperature of the cooling water tower, which depends on the ambient temperature and the working condition of the cooling fan; The backwater temperature mainly depends on the heating condition of the refrigeration host, but it is also related to the inlet water temperature.

In temperature control, we should pay attention to the following two points:

A. In order to protect the refrigerator, when the return water temperature exceeds a certain value, the whole air conditioning system must trip protectively.

B, the implementation of variable frequency speed regulation, should be preset lower working frequency.

2. Temperature difference control: The temperature difference △t between the cooling return water temperature t0 and the cooling inlet water temperature tA can best reflect the heating situation of the refrigeration host and the refrigeration effect.

The large temperature difference indicates that the main engine has more heat, so the speed of cooling pump should be increased to speed up the cooling water circulation; On the contrary, a small temperature difference means that the main engine generates less heat, so the rotation speed of the cooling pump can be appropriately reduced to slow down the circulation of cooling water.

When the inlet water temperature is low, the energy-saving effect is the main one, and the target temperature difference can be appropriately higher; When the inlet water temperature is high, the cooling effect must be ensured, and the target temperature difference should be low.

Frequency conversion water-cooled motor is a kind of machinery and equipment suitable for high temperature environment and frequency conversion speed regulation system.

The product has a unique cooling system, which can ensure the motor to run stably for a long time under the condition of high external environment temperature, and has the characteristics of high temperature, high humidity and corrosion resistance. Widely used in military industry, aerospace, sewage treatment, metallurgy, light industry, chemical industry, steel, cement, printing, sugar making, food, rubber, medicine, construction, lifting, transportation, woodworking machinery, instrumentation and other industries.

The special design and water cooling make the motor have a wide frequency modulation range of 3-50- 100HZ, excellent low frequency characteristics, high overload force and high efficiency. Can be equipped with water-cooled electric brake, water-cooled electric brake, water-cooled rotary encoder and reducer equipment.
