A professional head algorithm (vertical head) for the well pump to be placed Down hole:1. The professional explanation is: head = outlet pressure - inlet pressure. The test report at the factory is that the inlet pressure is zero (ie on the water) and the outlet pressure is the lift.2. For example: the pump has a maximum head of 50 M, and the pump is placed in a deep position below the water surfa...

1. The reason for the severe vibration of the pump is that the electric rotor is unbalanced or the coupling is poorly coupled, the bearing is worn and bent, some parts are loose and broken, and the pipe bracket is not strong. Adjustment, repair, reinforcement, straightening, replacement, etc. can be taken separately.2. The leaking or leaking of the pipeline may be due to the screw cap not tighteni...

The submersible pump (deep well pump) is a kind of water pump that directly puts the water pump in the water. It saves the trouble of the water pumping of the ordinary water pump, which saves the trouble of water pumping. When in use, the entire unit is submerged into the water to extract groundwater to the surface. It can be used for domestic water, mine rescue, industrial cooling, farmland irrig...

The working principle of the multistage centrifugal pump is the same as that of the surface centrifugal pump. When the motor drives the impeller on the shaft to rotate at a high speed, the liquid filled in the impeller is forced by the centrifugal force from the center of the impeller to the periphery of the impeller along the flow path between the blades. Since the liquid is subjected to the acti...

Utilizing the inexhaustible solarenergy everywhere, the system automatically starts working at sunrise, and thesunset is over, without the need for personnel to take care of it. Maintenancecosts can be minimized and it is an ideal green energy system t...

There are many classifications of centrifugal pumps, which are divided according to different structural characteristics..according to the number of working impellers1.Single-stage pump: there is only one impeller on the pump shaft.2. Multi-stage pump: There are two or more impellers on the pump shaft. At this time, the total lift of the pump is the sum of the lifts generated by n impellers..accor...

1. Ifthe pump has any minor faults, it must not be allowed to work.2. ifthe pump in the process of using a strong vibration, we must tentatively work,check what caused the cause. Otherwise it will cause damage to the pump.3. Theinterface between the pump and the pipe must be sealed, because if there is anydebris, it will damage the inside of the pump.4. afterthe use of the pump must pay attention ...

The selection of the waterpump should be based on four aspects of the liquidflow, head, piping layout and operating conditions.1、1. The pump flowrate is one of the important function data of the water pump selection. When selecting a pump, use the maximum flow as a basis toplan normal flow. Normally 1.1 times the normal flow is the maximum flow.2. The waterpump Max head is another important functi...

The discharge rate from solar powered pump depends on the radiation and not on the temperatures. In fact, the power generated from solar panels decreases (slightly) with increase in ambient temperature and thus, water outflow from a solar powered pump at higher ambient temperature will be slightly lesser than at a lower ambient temperature for the same level of incoming solar radiation on the sola...

A solar powered pump works like any other available and commonly used water pumps. The main difference is that solar powered pumps run on solar energy and do not require any fuel (diesel, kerosene, gas, etc.) or external source of electricity (from an electricity company) to deliver water.

The discharge rate from solar powered pump depends on the radiation and not on the temperatures. In fact, the power generated from solar panels decreases (slightly) with increase in ambient temperature and thus, water outflow from a solar powered pump at higher ambient temperature will be slightly lesser than at a lower ambient temperature for the same level of incoming solar radiation on the sola...

Solar panels that are installed for a solar powered pump normally have tamper-proof hardware to make it difficult for miscreants to take the panels away. Panels are mounted on the structure using anti-theft nuts and bolts, which make it difficult to open and to dismantle the modules from the structure. The only way a panel can be stolen is if those bolts are cut – an undertaking requiring a lot of...

Though it is possible to remove and re-locate solar panels, it is not advisable to change their location

A 2 HP solar powered pump can usually carry water over a horizontal distance of 700 metres, though pressure is somewhat reduced at the end of the plastic pipe. However, the flow of the water from the pump would also be influenced by the local regional topography. Hence, the above measures are tentative figures.DIFFUL is an innovative and technologically advanced solar pump manufacturer, specializi...

The following table can be used as an indicative guide for the selection of adequate ratings for solar powered pumps for different farm sizes:Solar Powered pump rate powerApproximate time required for irrigation per acre0.5HP20hours1HP14hours2HP7hoursHowever, other factors like the type of crop to be cultivated, soil type, climatic conditions, water table, etc., also play an important role in dete...

Any given pump has a rated capacity and maximum flow rate. As a result, increasing/integrating more solar panels as compared to the rated requirement for a particular capacity HP pump does not result in a higher water output.However, since solar powered pumps work on the output from the solar array, increasing the number of panels in some case may increase the number of hours that the pump can ope...

A solar powered pump is rather quick to install and to commission. If an existing diesel pump on an existing bore-well is to be replaced with a solar powered pump, field work of 3-4 days will be required. Generally, the installation of a solar powered pump will take about 3-4 days depending on the size of the installation. Examples from the field shows successful installation of a 7.5 HP solar pow...

It makes sense for a farmer to generally choose a solar powered pump under the followingcircumstances: 1.Installation of new pump in a farm2.Replacement of existing diesel/pumpin a farm

Kindly to know our DC brushless solar bore pumps are with permanent magnet synchronous motor, so not all the controller can be used for our pumps. The pumps should be matched with our own controller and our controller also can not be used for other pumps

We have two types of solar pump, the one with plastic impeller which is with 201 pump body. The other type is with 304 stainless steel impeller and 304 stainless steel pump body.

A PV system is made up of different components. These include PV modules (groups of PV cells), which are commonly called PV panels; one or more batteries; a charge regulator or controller for a stand-alone system; an inverter for a utility-grid-connected system and when alternating current (ac) rather than direct current (dc) is required; wiring; and mounting hardware or a framework.

You will more than likely have a small leak somewhere, if the pump is connected to the internals of the home. The first place to check is the toilet, in most case the washer in the toilet system is leaking letting water in, place a piece of toilet paper in the back of the toilet pan, if the paper gets wet, you have a leak.

If you want to have good tap pressure, than a pump is required, if you only want to hand water the garden and there is enough head pressure in the tank then you may not need a pump, but in most cases a pump is the better option.

A pool pump must be installed by a licensed or certified electrician or a qualified pool serviceman in accordance with the National Electrical Code and all applicable local codes and ordinances. Improper installation will create an electrical hazard which could result in death or serious injury to pool users, installers, or others due to electrical shock, and may also cause damage to property.

Yes….there is the risk of electrical shock or electrocution.
