Dry running refers to operating a submersible pump without water, leading to overheating, increased wear, cavitation, seal damage, and reduced lifespan. Prevent these issues with proper water supply, pump priming, and safeguards. Regular maintenance and a Velox Timer can help.
Isolators physically disconnect circuits for maintenance and safety, while breakers protect against overcurrents. They have distinct functions in electrical systems.
In business relationships, having clear terms and conditions and well-drafted contracts is crucial to mitigate conflicts and misunderstandings. Learn why it’s important to have contractual agreements and how they can provide clarity, manage risks, offer legal protection, and preserve positive relationships with clients.
Discover how procurement and contract management are vital for successful drilled borehole construction projects in Ghana, addressing water scarcity challenges and ensuring timely and cost-effective completion. Learn more about the process, resources, regulations, and best practices involved.
You have done everything you need or are required to do before drilling a borehole. Reconnaissance, Collection and comparing historical information about ground formation for the selected area, Geophysical Survey, etc. But can you actually tell the Exact or Actual Quantity and the Quality of water you will get before drilling?
Discovering underground water sources is a critical task, and relying on scientifically validated geophysical methods is recommended for accurate and reliable results. Using objects like coconuts or divining rods, associated with superstitious practices, lack scientific evidence and are not considered reliable. Instead, methods like electrical resistivity surveys, ground-penetrating radar, or seismic methods are used to assess the presence and characteristics of water-bearing formations. Traditional methods like divining or dowsing, observation of surface features, and gathering historical information can provide insights but are not scientifically reliable.
Choosing the right borehole site is crucial for a safe and reliable groundwater supply. Factors such as catchment, fracture zones, and contamination risks must be considered.
Relays and contactors are electrical devices used to control circuits. Relays are for low-power signals, while contactors handle high-power applications. Contactors have larger contacts, heavier-duty coils, and require higher voltage and current. They also have protective enclosures and more auxiliary contacts. In summary, relays are for lower current and voltage, while contactors are heavy-duty for high-power switching.
Learn about the main differences between capacitors and resistors in electronic circuits. Understand their functions, symbols, construction, and time response. Discover how farads and ohms measure different properties. Determine when to use a capacitor or a resistor based on specific applications and desired effects in the circuit. Capacitors store and release electrical charge, block DC current, smooth power supplies, create timing circuits, and filter signals. Resistors limit current flow, divide voltage, limit current, and set bias in transistor circuits. Farads measure capacitance, while ohms measure resistance.
Amps, watts, volts, and ohms are all units used to measure different aspects of electrical energy and properties of electrical circuits. Here is a brief explanation of each: To relate them to an everyday example, it’s like the flow of water (amps) through a hose is determined by the water pressure (voltage), and the rate […]
Discover the effects of low voltage on submersible pumps, from reduced performance to increased energy consumption and maintenance costs. Learn how to mitigate these issues and ensure proper functioning with our All Purpose Voltage Mediator – VRC360.
Chlorine tablets are one of the most commonly used water treatment methods because they are effective, reliable, and easy to use. Chlorine tablets are designed to release chlorine when dissolved in water. Chlorine is a powerful disinfectant that is capable of destroying bacteria, viruses, and other microorganisms that may be present in water and that […]
Here are some tips to keep your borehole with a submersible pump and underground chamber safe and clean: Regular Maintenance: It’s important to maintain the submersible pump and underground chamber on a regular basis, such as cleaning the strainer basket and removing any sediment or debris that might have accumulated. You can also do regular […]
There are several possible disadvantages of building a timer without using a magnetic contactor, including: 1. Risk of Overheating: Building a timer without using a magnetic contactor can put excessive load on the timer’s internal circuits. If the circuit is not designed to handle the load, the timer can overheat and potentially damage its internal […]
