Soft Start Water Pump Project in the Philippines

Due to geographical reasons, the Philippines is flooded. Meanwhile, industrial and infrastructure projects in the Philippines often face problems with power fluctuations and shocks during equipment startup. Think-Think-To solve these problems, our company provides soft start control cabinets for customers in the Philippines, aiming to achieve a smoother motor starting process and reduce the shock to the power system. The customer used this batch of soft start cabinets on flood control pumps to improve flood control capability, safeguard the safety of people and property in the Philippines, and promote economic development. After two years of time test, the product does not have any defects, warmly praised by the customer.

The usefulness of the motor soft start cabinet is mainly to realize the smooth start of the motor, reduce the current impact during startup, reduce the impact on the power grid and motor, and improve the service life of the equipment and the reliability of the system. In order to further understand the specific role and function of the motor soft start cabinet, can be analyzed in detail from the following aspects:

1. Reduce the impact of starting current

Control voltage and current: the soft start cabinet reduces the current impact by controlling the voltage and current during the motor starting process, so that the starting current increases gradually.
Avoid instantaneous high current: in full-voltage direct start, the motor starting current can be up to 4~7 times the rated current, while the soft start cabinet can limit the starting current to within 2~3 times the rated current, effectively avoiding instantaneous high current.

2. Reduce mechanical shock

Smooth torque change: soft start cabinet controls the output torque to make it change smoothly, reducing the impact on mechanical equipment and prolonging the service life of the equipment.
Avoid water hammer effect: in pumps and other equipment, the traditional starting method may lead to water hammer effect, soft start cabinet can effectively avoid this problem.

3. Extend the life of the motor

Reduce insulation aging: high current will produce a lot of Joule heat, accelerate motor insulation aging, soft start cabinet can significantly reduce this aging process.
Reduce mechanical wear: by reducing the mechanical impact of the starting process, soft start cabinet can reduce the mechanical wear of the motor and related equipment.

4. Improve system reliability

Reduce the impact of the power grid: soft start cabinet can reduce the impact of the starting current on the power grid to ensure the stable operation of the power grid.
Prevent overload tripping: by controlling the starting current, the soft start cabinet can effectively prevent circuit tripping due to overload, improve system reliability.
