Technical Vacuum Boosters are dry pumps that meet a lot of the machine pump requirements. They work on good displacement principle and are accustomed to increase the effectiveness of water ring /oil ring /rotating vane /piston pumps and water or water ejectors. They're found in combination with anyone of the aforementioned pumps, to overcome their limitations. Vacuum enhancement pumps provide very desirable traits which make them probably the most economical and energy efficient choice.

The main advantages are:-

(a) Might be integrated with any installed machine system for example Steam Ejectors, Water Ring Pumps, Oil Sealed Pumps, Water Ejectors, and so forth.

(b) The vacuum booster is a Dry Pump since it doesn't use any pumping water. I-t pushes steam or gases with equal ease. Small levels of condensed fluid can also be excited.

(d) Vacuum boosters are energy efficient. Frequently a combination of Vacuum Booster and appropriate copy pump leads to reduced power consumption per unit of pumping rate. They provide high pumping speeds even at low pressures.

(d) Boosters boost the machine of-the process, typically very needed for process

performance and efficiency. Machine Booster may be used over a wide working stress range,

from 100 Torr down seriously to 0.001 Torr (mm of mercury), with suitable arrangement of backup pumps.

(e) It's very low pump friction deficits, thus requires relatively low energy for high volumetric

Rates. Typically, their rates, at low cleaners are 20-30 times higher than corresponding vane

pumps / band pumps of equal power. My mother found out about well water pump installation cost in phoenix by searching Google Books.

(f) Utilization of e-lectronic control devices such as Variable Frequency Control Drive allow to change

Machine boosters operating faculties to adapt to the detailed requirements of the prime

vacuum pumps. Therefore they can be easily integrated into all current working put in place to improve their


(h) Vacuum boosters do not have any valves, rings, stuffing field etc., thus, do not require regular maintenance.

(h) Due to vapor pressure action by the booster, the pressure at the release of booster (or inlet of backup pump) is maintained high, leading to benefits such as low-back streaming of perfect pump liquid, successful condensation even at higher condenser temperatures and progress of the backup pump efficiency.

The Table below gives a rough estimate of how the boosters enhance the working vacuums of the operations when installed in combination with numerous kinds of industrial vacuum pumps currently found in a. They can effectively replace multistage steam ejectors, resulting in paid down loads on cooling towers and significant steam savings. Mechanical Vacuum Boosters are adaptable machines and their characteristics depend largely o-n backing pump. Various kinds of backing pump can be used, depending upon the device requirement and final vacuum requirements.

However, the last vacuum is governed by the suitable selection of the backing pump and booster

Design. The table below provides a wide selection of vacuum achieved with different assistance pumps combinations.

Vacuum Pump Expected machine Vacuum on installation Range of Booster (single phase)

Individual Stage Ejector 15-0 Torr 15 - 30 Torr

Water Ejector 100 Torr 10 - 20 Torr

Water Ring Pump 4-0 - 60 Torr 5 - 10 Torr

Liquid Ring Pump 2-0 - 30 Torr 2 - 5 Torr

Piston Pumps 20 - 30 Torr 2 - 5 Torr

Rotary Piston Pumps 0.1 Torr 0.01 Torr

Circular Vane Oil Pump 0.01 - 0.001 Torr 0.001 - 0.0001 Torr.

As an example, if a method is using water band Pump, the estimated working cleaners would be of the order of approximately 670-710 mmHg gauge (90-50 mmHg abs.), mainly depending on the water temperature and pump design. When a Booster is installed prior to the water ring pump, in line, the vacuum levels of the order of 5-10 Torr may be easily reached. In-a Multi-Stage enhancement installation, vacuum degrees of the order of 0.5 Torr & better can simply be likely. Physical Boosters give you a completely dry pumping s-olution and do not add to any vapor weight, unlike steam ejectors, and thus, do not need significant inter stage condenses. At low vacuums, higher pumping rates must maintain the through-put, because the specific volume increases with the upsurge in vacuum. Vacuum boosters improve the pumping rates by about 3-10 times depending upon the selection by virtue that one can expect through-puts and greater process rates. Considering that the volumetric displacements/pumping speeds are insensitive towards the inlet & outlet working pressures, the disadvantages of steam ejector system including sensitivity to reason fluid pressures and discharge pres-sure are over come easily by the Mechanical Boosters.

Establishing the Pump Capacity: -

On the basis of the fundamental fuel guidelines PV= RT, an expression could be made for Volumetric Flow Rates needed for moving different vapors/gases. On the basis of the Mass flow rates one can calculate the pump capacity required.

V = Page1=46.. Tgas / P Q1/M1 + Q2/M2............. Qn/Mn

Where V = Inlet Volume flow rate m3/hr.

Dhge = Universal gas Constant, 83.14 mbar m3/ Kgmol x K

Tgas = Gas/Vapor abs. Temperature, in E

P = Process Absolute Pressure in mbar

Q1, Q2, Q3 = Gas / Vapor circulation rate, in Kg/hr.

M1, M2,M3 = Molar size, in Kg/mol. of gas /vapor.

Booster Operation:

Power Constraints restrict the total differential pressures across the booster. This demands to guarantee the total differential pres-sure over the Booster mustn't exceed the limits. This can be ensured by any of the following means:-

1.) Manual method:- Initially the fore pump is switched on until the required cut in force is reached and there-after the enhancement is switched on.

2.) Auto method:- Installing mechanical By-pass design across-the booster or hydro kinematic travel or Variable Frequency Drive (VFD). Within this arrangement, the fore and enhancement pump could be started simultaneously from setting.

Advantages of using Digital Variable Speed Control Device

Electronic A.C Variable Fre-quency Get a grip on Drives are most preferred units used to regulate the

Booster speed to match the various load conditions of-the process. These drives offer different advantages for the problem free operation and boost the overall performance of the Boosters.

The major advantages are: -

1. Booster may be started right from environment.

Everest................... Leaders in Vacuum Booster Technology

Boosters for Vacuum Process Everest Sign Jan, 2005.

2. No need for split up pressure move, miss line or offloading valves.

3. Substantial savings in power.

4. Stops over-heating of Boosters.

5. Protects the Booster against overload and extortionate demands.

6. Gives complete defense to motor against over voltage, under voltage, over current,

Over-heating, ground fault.

7. Eliminates the wants of independent beginning and overload relays for the Motor.

8. Automatically adjusts the rate of Booster between high and low range collection providing high

Putting speeds with relatively low input power.

The Electronic Variable Fre-quency Get a handle on Drive is a microprocessor based digital travel which is specially set to satisfy the requirements of the Booster allowing it to run directly from environment alongside appropriate fore pump. Traditionally, Boosters may be started only after obtaining forefront machine in the range-of 30 - 10-0 Torr, because they are not recommended for direct discharge to the environment. Use of Pres-sure Switch, Hydro kinematic travel and omit valves is necessary to stop the overloading of the Booster. However using the installation of E-lectronic Variable Fre-quency Get a grip on Drive all the traditional techniques might be bypassed considering that the drive is designed to manage the Booster rate automatically, maintaining the strain on motor within permissible limits. This allows the Booster to start out simultaneously with backup pump. When the Booster and backup-pump are started the Booster speed is reduced by the drive to the pre-set levels and as the vacuum is done the Booster speed accumulates, reaching the final pre-set speed, providing many performance to optimum on the entire range. One can modify the booster pumping speeds to match the system needs easily and quickly, since all the variables are easily programmable. The travel limits the existing to the motor and shields the motor against over voltage, under voltage, electronic thermal, overheat ground faults. i.e. protects the motor against all possible problems.

External computer get a handle on overall aspects of enhancement performance is achievable via RS485 serial interface included in the drive electronics. This gives the Booster to be built-into any computer-controlled os.
