Q:how to install a main pipe water pump to service the community?

Installation of water pump is very easy, any certified plumber and electrician can install electric water pump. Your question maybe is, how to design water pump water system to service the community? To determine the correct rating of water pump to be used and to design a water system, here are the steps : 1) Determine the safe discharge yield of your well for your water source, by series of tests. This will enable you to know discharge rate of well and the draw back time of water after pumping. This data will be used for designing a pump (its discharge capacity). Note that pump discharge capacity should be lower than well safe yield capacity in order not to drain the well. 2) Determine the suction lift or height of water table in the well by measuring the height from water table up to the top of the well. This data will be used for pump design (its suction lift/height capacity). Pumps suction lift varies depends on its Horsepower capacity and the type of pump (submersibble or centrifugal). 3) Determine number of households in the community. This data will be used for the design of reservoir (tank) for your water system and the number of hours for the pump to operate to fill the tank. Note that the average usage of water is 120 liters per day per capita. So the more the number of population, the bigger the tank and the longer the pumping time in order to meet the per capita usage. 4) Determine the elevations from your water source towards the community to be served. Use survey instrument to determine the elevations. This data will be used to design a height of the tank and the sizes of service pipes towards the community. The higher the difference in elevation from your source towards community, the lower the height of the tank and the smaller the sizes of service pipes. Sizes of service pipes can be determined by hydraulic heads (heights). By following these steps, I gues you can now design and construct a water system.

Q:Is this a symptom of a bigger problem or do I just need to replace the water pump?

either the water pump gasket is leaking, or the water pump impeller seal is leaking. bith can be fixed by replacing the water pump. after replacement make sure to check for any other leaks.

Q:What is the relationship between pump power, lift and flow?

When the power is constant, the kinetic energy theorem is known as P=F*V, that is, W=F*S.In the water pump, it is said that the work done by the unit time pump = the gravity of the water flow * the displacement of the waterIt can be seen that:1, the power is certain, the head and the flow is inversely proportional.2, the greater the power, the greater the product of the head and flow.Therefore, when the flow is minimum, the pump head is the maximum; when the head is the minimum, the flow is the maximum.

Q:I am about to replace the timing belt in a 3.4L Toyota V6 at approximately 85,000 miles. The motor has had the Toyota red coolant, which lubricates a water pump very well. Should I, Or should I not replace a Toyota Water Pump also, at this mileage (85,000)? Could the original water pump last until 170,000? Thank you

It's recommended to change the water pump also because your labor cost to open the engine to change the belt, is the exact cost of any future labor cost to change the water pump which, will go bad, eventually. The original pump could last until 170,000 miles but why chance it when the engine is already opened up.

Q:Just touch this area, a lot of places do not understandFor example, I have a water pump, for 11kw, choose circuit breaker, then what model should be chosen more appropriate, it is best to recommend a Schneider, universal DW recommend oneCan explain in detail, better, I checked online selection manual, there are many places that feel fuzzyIn addition, 37KW, 22KW, 1.5KW each choose what type?Hope predecessors give advice

If it is a single-phase motor, rated current is 75A; three is about 30A; the contactor should be 1.1-1.5 times the rated current of the motor protection type selection of circuit breaker, circuit breaker: RMM1-100/33002 or 50A motor comprehensive protector, the price is not expensive.The circuit breaker (English Name: circuit-breaker circuit, breaker) refers to the closing, carrying and breaking current conditions and normal circuit switch device, load and breaking current loop abnormal conditions within the stipulated time. The circuit breaker is divided into high voltage circuit breaker and low voltage circuit breaker according to its range of use. The demarcation line of high and low voltage is fuzzy. Generally, more than 3kV is called high-voltage equipment.The circuit breaker can be used to distribute electricity, not frequently start asynchronous motors, the protection of the power line and a motor, can automatically cut off the circuit when they occur serious overload or short circuit and under voltage fault combination, its function is equivalent to the fuse switch and less thermal relay etc.. Moreover, after breaking the fault current, there is no need to change the components. At present, it has been widely used.Distribution is an extremely important link in the generation, transportation and use of electricity. Distribution systems include transformers and various high and low voltage electrical equipment. Low-voltage circuit breakers are a wide range of electrical equipment.

Q:The actual way to move water (liquid) from a pond with small bits of debris. Trying to find out which system is the most efficient: vane, impeller, rotary, centrifugal...etc...either by hand or using a bicycle to turn the pump. I do NOT want to use an engine or electric motor. I've read about the transfer pumps in the hardware store are only about 50% efficient, I need something better that will provide me a continuous output. Something lightweight that will handle pressure. Any ideas? Thanks in advance!!

Most efficient (fewest parts) is a lift pump. The simplest example is if you use a bucket. You can make this easier to use with a few extra parts to make a shadoof the only losses are friction in the pivot and any leakage that takes place.

Q:Fully automatic self-priming pump

Yes, design according to your different working conditions. For example, water pressure pump is pressure control, water pressure is low will automatically start, the pressure automatically shut down.

Q:How does a pump get water from a low low elevation to a higher elevation.

The simplest form of water pump is a plastic spiral where the outermost spiral dips under the water and out as it rotates. The spiral can be driven by attached paddles if the water is flowing. As the water progresses down smaller spirals the pressure increases. The water exits through a rotating coupling at the centre of the spiral. A single stage pump can only raise water 15 feet (1 atmosphere) A windmill is a good example of a simple pump where a lever moves up and down, A valve closes at the bottom of a tube on the up stroke and raises the water by the length of the stroke. This water opens a second valve near the top of the tube as soon as the upstroke starts and the water is pushed up. This pump does not work by creating a vacuum. On the downstroke the upper valve closes due to the raised water pushing on it, and also due to its own weight, and the lower valve opens from the water below pushing on it as the cylinder descends. At the end of the downstroke the valve closes under its own weight and the weight of the water above it and the cycle repeats To raise water higher than 15 feet using a windmill, it is necessary to install a small tank at, say 14 feet, with a second lower and upper valve in a tube. The first stage pump fills the tank which the second stage pump then lifts another 15 feet, This process can be repeated until the water reaches the surface, but a bigger windmill will be needed to power multiple pumps

Q:Was able to remove all bolts except the one in the rear of engine one of the bigger bolts the pulley from the serpentine belt blocks itdoes the pulley need to be removed and if yes then how

yes you,ll probably have to remove the pulley from it to get to all of them,i usually remove the pulley first anyway ,this makes it a lot easier to do ,but you should be able to get to the bolt after the pulley is off,good luck i hope this help,s.

Q:What are the export pumps packed in cartons?

Our exports are packed in specially made export special wooden cases. The water pump bolts are fixed at the bottom of the wooden box through the anchor bolt hole, then wrapped in plastic bags, and then sealed.
