Variable Speed Drive ( VSD )

Aplikasi variable speed banyak  diperlukan dalam industri. Jika sebelumnya banyak dipergunakan system mekanik, kemudian beralih ke motor slip/ pengereman maka saat ini banyak menggunakan semikonduktor. Tidak seperti softstarter yang mengolah level tegangan, inverter menggunakan frekuensi tegangan masuk untuk mengatur speed motor. Seperti diketahui, pada kondisi ideal (tanpa slip).

Jadi dengan memainkan perubahan frekuensi tegangan yang masuk pada motor, speed akan berubah. Karena itu inverter disebut juga Variable Frequency Drive.

Prinsip kerja inverter yang sedehana adalah :

  • Tegangan yang masuk dari jala jala 50 Hz dialirkan ke board Rectifier/ penyearah DC, dan ditampung ke bank capacitor. Jadi dari AC di jadikan DC.
  • Tegangan DC kemudian diumpankan ke board inverter untuk dijadikan AC kembali dengan frekuensi sesuai kebutuhan. Jadi dari DC ke AC yang komponen utamanya adalah Semiconduktor aktif seperti IGBT. Dengan menggunakan frekuensi carrier (bisa sampai 20 kHz), tegangan DC dicacah dan dimodulasi sehingga keluar tegangan dan frekuensi yang diinginkan.

Untuk pemasangan inverter sebaiknya juga dipasang unit pengaman hubung singkat seperti Seconductor Fuse atau bisa juga Breaker. Ini seperti pada pemasangan softstarter hanya saja tanpa contactor bypass.

 

Pengontrolan start, stop, jogging dll bisa dilakukan dengan dua cara yaitu via local dan remote. Local maksudnya adalah dengan menekan tombol pada keypad di inverternya. Sedangkan remote dengan menghubungkan terminal di board control dengan tombol external seperti ,button, atau switch. Masing- masing option tersebut mempunyai kelemahan dan keunggulan sendiri- sendiri.

Frekuensi dikontrol dengan berbagai macam cara yaitu : melalui keypad (local), dengan external potensiometer, Input 0 ~ 10 VDC , 4 ~ 20 mA atau dengan preset memori. Semua itu bisa dilakukan dengan mengisi parameter program yang sesuai.

 

Beberapa parameter yang umum dipergunakan/ minimal adalah sebagai berikut (istilah/nama parameter bisa berbeda untuk tiap merk) :

  • Display : Untuk mengatur parameter yang ditampilkan pada keypad display.
  • Control : Untuk menentukan jenis control local/ remote.
  • Speed Control : Untuk menentukan jenis control frekuensi reference
  • Voltage : Tegangan Suply Inverter.
  • Base Freq. : Frekuensi tegangan supply.
  • Lower Freq. : Frekuensi operasi terendah.
  • Upper Freq. : Frekuensi operasi tertinggi.
  • Stop mode : Stop bisa dengan breaking, penurunan frekuensi dan di lepas seperti starter DOL/ Y-D.
  • Acceleration : Setting waktu Percepatan.
  • Deceleration : Setting waktu Perlambatan.
  • Overload : Setting pembatasan arus.
  • Lock : Penguncian setting program.

Jika beban motor memiliki inertia yang tinggi maka perlu diperhatikan beberapa hal dalam acceleration dan deceleration. Untuk acceleration/ percepatan akan memerlukan torsi yang lebih, terutama pada saat start dari kondisi diam.

Pada saat deceleration/ perlambatan, energi inertia beban harus didisipasi/ dibuang. Untuk perlambatan dalam waktu singkat atau pengereman, maka energi akan dikembalikan ke sumbernya. Motor dengan beban yang berat pada saat dilakukan pengereman akan berubah sifat menjadi “generator”. Jadi energi yang kembali ini akan masuk ke dalam DC Bus Inverter dan terakumulasi di sana karena terhalang oleh rectifier. Sebagai pengamanan, inverter akan trip jika level tegangan DC Bus melebihi batas yang ditoleransi.

Untuk mengatasi tripnya inverter dalam kondisi ini diperlukan resistor brake. Resistor brake akan membuang tegangan yang lebih dalam bentuk panas. Besar kecilnya resistor brake ini sangat tergantung dengan beban dan siklus kerja inverter.

Booster Pump

Pompa Pendorong / Booster Water Pump / Otomatis Pressure Switch

Untuk memenuhi kebutuhan air sehari-hari, di butuhkan minimal 1 buah pompa air untuk mendistribusikan dari sumber ke seluruh titik air ( sumber air bisa dari sumur,atau penampungan ) . Untuk memudahkan mengkonsumsi air, biasanya kita membangun tower air dengan ketinggian tertentu. Dengan sistem pompa air menghisap air dari sumber untuk di simpan pada tower air. Selanjutnya dengan tower air, yang memanfaatkan gaya gravitasi, air mengalir melalui pipa tanpa bantuan pompa.
Dalam kondisi ini biasanya tekanan air hanya cukup untuk memenuhi kebutuhan mencuci maupun mengisi bak kamar mandi. Tetapi apabila kita mandi menggunakan shower, tekanan air biasanya kurang memuaskan. Apalagi bila kita menggunakan water heater gas. Water heater gas umumnya membutuhkan tekanan air sebagai salah satu mekanisme pemantik untuk menyalakan api untuk memanaskan air. Sehingga bila tekanan air kurang pemantik tidak akan berfungsi dengan baik. Selain itu mesin cuci modern umumnya mensyaratkan tekanan air tertentu untuk dapat berfungsi dengan baik. Oleh karena itu membutuhkan tambahan pompa untuk dapat memenuhi kebutuhan ini.
Salah satu solusi yang umum di gunakan adalah menggunakan pompa sumur dangkal yang dilengkapi dengan otomatis. Otomatis pada pompa ini menggunakan jenis pressure switch. 
Pompa booster merupakan alternatif penggunaan produk pompa sumur dangkal otomatis yang biasa kita kenal. Pompa booster adalah jenis pompa yang berfungsi hanya untuk menambah tekanan air, dengan demikian pompa tidak dapat di gunakan untuk menghisap air dengan posisi sumber air di bawah pompa. Sistem otomatis menggunakan sejenis bola magnet, yang bekerja bila ada aliran air.

Pompa otomatis dan pompa booster merupakan sistem penambah tekanan air, yaitu apabila kran dibuka pompa ON, kran ditutup pompa Off.

Planning guide

 

Inlet pressure

The maximum inlet pressure (see Technical data) must be taken into account when configuring the system. The maximum permissible inlet pressure is calculated from the maximum operating pressure of the system minus the maximum pump delivery head at Q = 0

Pressure reducer

Fluctuating inlet pressure is compensated by the speed control integrated into each single pump as long as the pressure fluctuation is not greater than the difference between the setpoint pressure value and the zero-delivery head of the single pump at minimum speed. If the pressure fluctuation is greater, a pressure reducing valve must be installed upstream of the system.

Volume flow

Up to 155 m3/h (43 l/s) system configuration in accordance with DIN 1988 (EN 806); with standby pump up to 185 mm3/h (51 l/s) during operation of the standby pump as an auxiliary peak-load unit

Residual-current-operated protection

switch

When installing residual-current-operated protection switches in conjunction with frequency converters, bear in mind that only universal-current-sensitive residual-current-operated protection switches in accordance with DIN/VDE 0664 are to be fitted.

Wilo-WMS low-water cut-out switchgear

The series Helix VE pump being used is already equipped with an integrated dry-running detection as safety equipment for the pump. Nevertheless, the installation of a low-water cut-out switchgear is required in cases where the pressure boosting systems are connected directly to a public mains power supply; that prevents the inlet pressure in the mains supply line from falling below 1.0 bar. Please order directly when ordering the pressure boosting system. The WMS will then be installed in the pressure boosting system, electrically wired and fully tested by Wilo during the final functional test.

Standards/directives

The overall system conforms with the requirements of

  • DIN 1988 Part 5
  • DIN 1988 Part 6* (**)

* The specifications in DIN 1988 (EN 806) and of the water-supply companies are to be observed. Regarding the electrical components, the system conforms with the requirements of

  • VDE 0100 Part 430/Part 540
  • VDE 0110 Part 1/Part 2
  • VDE 0660 Part 101/Part 107 and
  • DIN 40719/IEC 754

Always observe the specifications in DIN 1988 (EN 806) when using and operating the pressure boosting system.(**) That does not apply to fire extinguishing systems in accordance with DIN 14462. Please request these separately.

Commissioning

 

  • If pumps with 2900 rpm are installed inside residential buildings, then corresponding noise reducing measures are to be implemented.
  • Pump curves and specific motor powers depend on the respective fluid being pumped. Pump curves and power vary considerably when fluids are conveyed that differ from water in thickness and/or viscosity. For this, please observe the table “Recommended limit values for dimensioning”.
    The recommended limit values for dimensioning are calculated as follows:
    Qoptimum (volume flow at which the pump reaches its best efficiency), to be read from the individual pump curve; factors Qmin and Qmax , to be taken from the table “Recommended limit values for dimensioning”.Qmin dimensioning = Qmin x Qoptimum
    Qmax dimensioning = Qmax x Qoptimum
    Example: Size NL 32-125
    Qmin = 0.3 x 8 = 2.4 m3/h
    Qmax = 1.2 x 8 = 9.6 m3/h
  • Load-sensitive pump output
    All Wilo standard pumps are equipped with IEC standard motors. The Wilo control devices are suitable for automatic load-sensitive speed control of pumps that are driven by any standard motors of conventional manufacture.

General notes – ErP (ecological design-) directive

 

  • The benchmark for most efficient water pumps is MEI ≥ 0.70
  • The efficiency of a pump with a trimmed impeller is usually lower than that of a pump with the full impeller diameter. The trimming of the impeller will adapt the pump to a fixed duty point, leading to reduced energy consumption. The minimum efficiency index (MEI) is based on the full impeller diameter.
  • The operation of this water pump with variable duty points may be more efficient and economic when controlled, for example, by the use of a variable speed drive that matches the pump duty to the system.
  • Information on benchmark efficiency is available at www.europump.org/efficiencycharts
