As the name implies, an automatic booster pump is a system designed to operate autonomously without requiring manual initialization once it's set up. Unlike a single booster pump, which cannot function automatically on its own, an automatic system requires the integration of an intelligent controller and additional components to manage its operation. The controller acts as the central brain of the automatic booster pump, determining its level of intelligence and reliability. There are various types of controllers available, each with different operating mechanisms, but they all ultimately follow the same basic principle. Based on their working mechanism, controllers can be categorized into three main types: pressure-based, level-based, and inverter-based.
Once the level-based booster pump is operational, it will stop running when the water level in the tank or reservoir reaches a pre-set high level. When the user consumes water and the level drops to the pre-set low level, the pump restarts. This cycle continues, ensuring a continuous supply of water. The float can be adjusted to set different operational points, allowing for flexible control based on specific needs. A system diagram of the level-based booster pump is shown in Figure 2.
In a differential pressure booster pump system, the pump starts when the pipeline pressure rises to the upper limit and stops when the pressure drops to the lower limit set by the user. This process repeats continuously, maintaining stable water pressure throughout the network. The pressure values can be easily adjusted using the pressure gauge, making it simple to modify the operating points. The system diagram for the pressure-based booster pump is illustrated in Figure 3.
The inverter-based booster pump works by setting a desired pressure value. Pressure sensors continuously monitor the pipeline pressure and send feedback to the controller. The controller compares the actual pressure with the user-defined setpoint and adjusts the pump speed accordingly to maintain constant pressure. This allows for precise and efficient water supply. The pressure value can be directly set on the controller, offering a high degree of flexibility. A system diagram for the inverter-based booster pump is provided in Figure 4.
Stainless Steel Washer
stainless steel commercial flat washers are used under bolt heads or nuts to increase the bearing surface area, or to offer protection so that the nut or bolt can be rotated without distortion of the bearing surface. Flat washers are also used to give tightness to a joint, to prevent leakage, and especially to distribute pressure under the head of a bolt or nut. Dimensional specifications are governed by ASME B18.21.1. Commercial flat washers generally have a larger outer diameter than SAE (Society of Automotive Engineers) flat washers, and can be utilized in nearly any application. stainless steel fasteners are commonly used in applications that require general atmospheric corrosion resist ance, such as chemical and food processing equipment. Stainless steel has a higher corrosion resistance than carbon steel.
