In the electrical and motor control area it is well known that a soft starter can improve the efficiency and lengthen the life of the motor itself by controlling the electrical current surge during motor start-up. There is also a well known fact, that due to the price point of some motors or systems the added expense of a soft starter may not justify the extra expense of another industrial component. However when considering the overall system the soft starter also lengthens the life of connected mechanical components by putting less torque on the linkage, powertrain, conveyors, etc. In this post we talk about the value a soft start brings to liquid pumping systems.
Powering a hydraulic system while protecting the pipes and joints does not have to mean sacrificing speed. Not only is there the initial hurdle of safely powering motors and other electrically powered elements while protecting them from moisture damage, but also there is further concern about gaining the fine starting, stopping, and overall control necessary to power systems without an excess of wiring, hoses, and other bulky components. Get improved control over your plant’s systems and protect against the damages of water hammering with the NEW compact soft start/soft stop Motor Starter P 4.0 from TELE.
Meet the Worlds Smallest Motor Starters for Protection of Electric Motors, of up to 4 kW / 5.5 hp. The device combines 4 functions; Soft Starter, Reversing unit, 3-pole Shutdown, and complete motor Thermal Protection all in a 22.5 mm width housing.
The space saving and slim soft starter, is designed, to drive up to 4 kW motors. Two control inputs define clockwise, and counter-clockwise rotation. The reversing logic integrates all components, so no external wiring is required. The soft-start/soft stop, offers a shock-free start/stop behavior. This offers maximum protection for the power supply, motor and what its coupled with. Start time and starting torque, can be adjusted from the front of the device. In addition to the soft start and stop functions, the intelligent motor starter, enables the user to change the motor direction remotely.
The current monitoring function, provides a blocking protection of the motor and machine during the startup phase. Adjustment is again done via a simple knob on the front. In case of error, a relay contact, and LED indicates the fault state. Integrated bypass relays are energized once the motor starts, for maximum motor efficiency.
This soft start motor combines the benefits of multiple electronic controls in one compact housing to reduce space without sacrificing function. With its reduced size and multiple features you will also reduce the space needed for cabling and materials in the control cabinet. The Compact Motor Starter P 4.0 provides a wealth of control without impeding on space needs.
Problems with Pumping and Pipe Hammering? A Motor Soft Starter can Eliminate this by Controlling the Pump and Regulating the Proper Pressure
The technical term for this phenomenon is called hydraulic shock, and it occurs when liquid stops or changes directions suddenly. The hammering is either the banging you hear from the force of that fluid physically make the plumbing/pipes move and strike against one another or against things that are nearby. Water hammer can be so forceful that it will break pipes or loosen joints. In plastic or rubber tubing this sometimes can’t be heard but these can flex or expand to the point of breakage or significant pressure losses over time due to being permanently “stretched”. Even in non-precision applications this needs to be looked after and in a precise application such as a medical device this could pose a huge problem.
Compact Motor Start P 4.0 provides the control you need to prevent water from hammering the pipes and causing increased speed of wear. While slim, the Contact Motor Start P 4.0 provides the power and control to operate the start and stop of pipe systems. The soft start and soft stop allow for a system that won’t simply dump water pressure all at once but allow its release in a controlled way that avoids a pressure peak.
Soft Start Control
This is essential for systems that rely on flexible tubes connected to the main pipe via snap-in fittings or couplings. With the control provided by the Compact Motor Start P 4.0, water pressure is initiated in a controlled manner, which helps to prolong the lifespan of pipes, couplings, and fittings — get more operating time from your system when it is not being hit by a powerful flow of water at every startup. Instead, a soft start does not expose pipes to strong water pressure immediately during the startup process; it increases the pressure in a controlled manner, helping your system to stay in good condition longer.
Stop Systems With More Ease
Soft stop capability further helps to protect your system. When stopping the pump, reverse pressure means that check valves will not immediately shut down. Soft stop control helps the system to shut down in a moderate fashion to not cause damage. More importantly, it prevents a hammering effect and increases the life-span of the valves.
Take better control and extend the life of your system with better-functioning industrial components. Fortunately, with the help of TELE’s capable design, you can get the control you need without excess bulk. The Compact Motor Starter P 4.0 gives you control over soft starts and soft stops in a slim design that does not overwhelm a control cabinet.
