Many facilities are facing issues such as increased starting current, breaker malfunctions, and insufficient generator capacity. In particular, top runner motors (high-efficiency IE3 motors) have a starting current that is 1.1 to 1.4 times higher, increasing the burden compared to older motors (IE1). This has led to breaker trips and insufficient generator capacity. Effects of soft starters: Reduction of starting current → Prevention of breaker malfunctions, no need for increased generator capacity Prevention of water hammer → Gradual deceleration during pump shutdown to reduce piping damage and noise Extension of machine lifespan → Prevention of belt breakage, shaft damage, and gear damage Prevention of load collapse → Prevention of load collapse due to sudden stops of belt conveyors Prevention of damage to propellers and high-viscosity mixers → Reduction of shock during startup

What is a press flange: A press flange is an ultra-lightweight steel flange. It is characterized by its lightweight and easy installation, having been reduced to one-third the weight of conventional products through the pressing method. Background of the test: Due to concerns about durability raised by the unique appearance of the press flange, a pressure test was conducted.

Hashimoto Sangyo sells drainage pumps that can be installed in locations where there is no slope and natural drainage is difficult, allowing for the installation of sinks and toilets. The pump activates immediately when drainage flows in and automatically stops when the drainage ends. Even in cases where a slope cannot be created, it is possible to freely add or install new water facilities. Relocation and removal are also easy, making it suitable for temporary toilets.

This is a guide for control devices for slow start-stop. With the three-phase induction motor (motor) now meeting the IE3 standard, the starting current has significantly increased. When updating fire hydrant pumps or smoke exhaust fans, I've heard that costs rise due to increasing generator capacity, adding inverters, and related harmonic measures. By controlling the voltage for the start and stop of pumps and blowers, the starting current can be reduced, and water hammer can be eliminated.

When updating fire hydrant pumps and smoke exhaust fans, I've heard that costs have risen due to increasing generator capacity, adding inverters, and associated measures for harmonics. By controlling the voltage for the start and stop of pumps and blowers, the starting current can be reduced, and water hammer can be eliminated.

The cause of water hammer is hypothesized to be related to flow rate, and we measured the internal pressure under different flow rates. Additionally, water hammer can be recreated by gradually lowering the voltage when the pump is stopped.
