Cara Kerja Pompa Air

. Pada dasarnya setiap pompa air dilengkapi dengan peralatan otomatis ketika kita membeli mesin pompa air, ini berguna untuk memudahkan kita pada saat pengoperasian, sehingga waktu kita menjadi lebih efektif dan efisien dan tidak memerlukan aktifitas menghidupkan ataupun mematikan pompa,sebab sudah ada sensor otomatisnya, yang bekerja berdasarkan tekanan yang terdapat pada pipa atau saluran air pada keluaran pompa.

. Pada mesin pompa air ada saluran hisap dan ada saluran buang, alat otomatis atau sensornya menggunakan sensor tekanan atau disebut juga Pressure Switch dan dipasang pada tabung pada saluran keluaran pompa, ketika pompa dihidupkan atau dihubungkan dengan tegangan jala-jala, maka pompa akan berputar sehingga dibagian dalam pompa terjadi vaccum karena adanya perbedaan tekanan, sehingga air yang ada didalam tanah akan terhisap naik.

. Pada saat mesin pompa air berputar dan semua kran air yang ada dirumah tertutup maka pada saluran keluaran pompa akan timbul tekanan yang cukup besar, ketika tekanan yang dihasilkan melebihi tekan set yang ada pada sensor atau pressure switch maka sensor akan bekerja dan pompa air akan mati seketika, pompa air akan hidup lagi jika ada salah satu kran air terbuka disebabkan tekanan air sudah turun dan begitulah seterusnya.

. Dengan demikian saat kita lupa untuk mematikan pompa air, maka mesin pompa air tidak akan terbakar disebabkan kerja yang terus menerus, dan lagi kita tidak perlu memasang atau mencabut steker dari mesin pompa air sebab segalanya akan bekerja secara otomatis.

Saving Energy - Grundfos Pumps

saving-energy-grundfos-pumpsALL YOU NEED TO KNOW ABOUT PUMPS AND ENERGY THIS IS FOR Saving Energy – Grundfos Pumps

 

 

Pumps are involved in nearly every aspect of modern living. They are used to move fluids such as liquids, slurries or gasses.

Saving Energy – Grundfos Pumps.

In businesses, buildings, households and industries, pumps exist – in some form or another. They are key components in maintaining comfort levels in buildings. for Saving Energy – Grundfos Pumps They deliver and distribute clean drinking water from water treatment plants throughout cities, while at the same time removing wastewater. And, they are highly present within a wide range of industries to Saving Energy – Grundfos Pumps. The world depends on them, but many pumps are also serious energy wasters, leaving behind a significant carbon footprint for Saving Energy – Grundfos Pumps. This is because today’s pumps account for no less than10% of the world’s electricity consumption and because the majority of electricity is still produced using fossil fuels [1].

Pumps and the world’s electricity consumption procent_billede

Today pumps account for no less than 10% of the world’s electricity consumption.

Two third of all pumps use up to 60% too much energy [2].

If every business switched to a high efficiency pump system there could be global savings of 4% of the total electricity consumption- comparable with the residential electricity consumption of 1 billion people.

The Centrifugal Pump - KAMJaya

The Centrifugal Pump

In 1689 the physicist Denis Papin invented the centrifugal pump and today this kind of pump is the most used around the world. The centrifugal pump is built on a simple principle : liquid is led to the impeller hub and by means of the centrifugal force it is flung towards the periphery of the impellers.
The construction is fairly inexpensive, robust and simple and its high speed makes it possible to connect the pump directly to an asynchronous motor. The centrifugal pump provides a steady liquid flow, and it can easily be throttled without causing any damage to the pump.

If a pressure difference occurs in the system while the centrifugal pump is not running, liquid can still pass through it due to its open design.

The difference demands on the centrifugal pump’s performance, especially with regard to head, flow, and installation, together with the demands for economical operation, are only a few of the reasons why so many types of pump exist.

 

Grundfos pumps - Digital Dosing pumps

Overview for Grundfos pumps – Dosing pumps

Grundfos DME Digital Dosing pumps combine perfect precision with user-friendliness, covering large dosing quantities in the range from 60 l/h to 940 l/h with few variants.

Digital Dosing Pumps

The use of stepper motor/EC drives optimizes control of the stroke speed and makes it extremely accurate. The duration of each pressure stroke varies according to the flow setting. The suction stroke time always remains constant but can be lengthened using the anti-cavitation function and thus adapted to the relevant needs. This way suction always takes place with the full stroke volume. This results in continuous dosing and lower pulsation in the dosing system – important factors in ensuring smooth pumping of outgassing media and in installations requiring longer suction lines.

The DME pumps range has all the benefits of the highly acclaimed smaller Digital Dosing range, making accurate dosing easier than ever.

Precise Pumps and easy setting Pumps

The operator can easily install and set the pumps to discharge exactly the quantity of dosing liquid required in the application. In the display, the setting of the pumps is read out directly in ml/h or l/h, pulse or batch. The operation mode is easily identified by means of icons.

Pumps Turndown ratio 1:800

With a turndown ratio ten times better than that of traditional equipment, the DME Digital Dosing pumps offer maximum flexibility and accuracy.

Turndown of the suction stroke to 75 %, 50 % or 25 % of the maximum speed ensures optimal priming pumps and displacement of even the most difficult liquids.

Unique technology Pumps

A unique drive technology and microprocessor control make sure that liquids are dosed precisely and with low pulsation, even when the pumps is operating with high viscosity or degassing liquids. Instead of the conventional stroke length adjustment, the capacity of the DME is regulated by automatic adjustment of the motor speed during the discharge stroke, and by fixed suction stroke speed. This guarantees optimal and uniform mixing.

Fieldbus Pumps communication

Available with Profibus interface to supply performance data and status information for quality control, preventive maintenance and future reference.

Pumps Overload protection

Built-in overload protection monitors the counter-pressure of the pumps and protects it against too high pressure loads.
