Water pressure is the force with which the water enters your house and gets distributed thru the pipeline provided. The more is the volume of water entering the pipe, the greater is its pressure. Continuing to have a low pressure is really very irritating, as it takes unduly long to fill the tub in the bathroom of even the washing of pots and pans in the kitchen. Likewise, it causes poor and inadequate flushing in the toilets. However, it’s not something that can’t be taken care of. You can always adopt means to get water at increased pressure. Here are some of the ways to get improved supply of water at home.

1. First of all you should try to assess the source that is causing the drop in pressure. Check the plumbing for any water leaks. There could be some obstructions in the pipeline itself. If any of the problems is noticed you have to ask for the services of a plumber.

2. Quite often one feels that the pressure is low at one particular point say, the sink or the toilet. That can generally be taken dare of easily. It may be due to a clog in the plumbing system and needs plunging. Kitchen pipes often get blocked and may need plunging or a chemical in the form of a drain cleaner for getting clean. At times, the aerator housed at the end of the sink faucet could contain accumulated sediment, needing to be cleaned and removed. Aerator is a small screen positioned within the head of the faucet. After cleaning and putting it back to its position, check the flow of water. In case of showers, it may be that the showerhead needs to be cleaned or at the most you may be required its replacement and get water at increased pressure.

3. The other way to get water at higher pressure throughout the house is to install a water pressure booster arrangement. Technically, it’s just an additional pump that assists the original pump, already installed, to increase the flow of water entering your home. This pump is installed next to the water line entering your home. The additional water removes the air from the pipe, fills it with more water and you get water at increased pressure.

4. You may check the pressure using a water gauge on the pump while it is still running. The gauge should read about 35 PSI and if the reading is lower than that, you may increase the pressure by getting the pump recalibrated. You can also corner the problem thru the installation of pressure tank with a check valve that raises and also maintains the pressure of incoming water.

Water PRessure Booster Pumps – The Way They Work

The function of a booster pump is to supply water at a higher pressure within the house when the pressure of incoming water is too low. These pumps come in different designs, depending on the application, and can be employed in isolated areas or can be installed in the pipeline of a large residential or commercial complex where water pressure is very low. The size and specification of these pumps typically depend on the design of waterline laid and the history of the building. Usually older buildings need these pumps more often

One of the main reasons for low water pressure in residential areas is the growth of infrastructure. A particular locality might have been originally designed to accommodate say a thousand families, but in a span of ten or twenty years, it may already be having two thousand families. Though the population of the area has doubled, there has been no change in the design or size of the pipeline feeding water to the locality. So, it’s the poor planning that often results to such a situation. One option to overcome the malady is the replace the entire pipeline of the house, but that’ll be very expensive and time consuming too. Fortunately, there’s another economical and convenient option.

Water booster pumps forcibly pull water thru the pipes connected to your house. That increases the speed and pressure of incoming water without having to replace the piping. Though it is much convenient than undertaking all the digging needed for pulling out the older pipes and replacing them with the newer ones, there are some limitations. As a matter of fact, homeowners or businesses need to take formal approval from the municipal authorities for installing their own personal pumps to boost up the pressure of incoming water. But, they realize that getting such a permission to handle city piping can be difficult. One single mistake can prove to be very costly. You need to have a lot of patience to get permission for using your pump, but it is worth doing as it solves the problem of water pressure being fed to your home.

On finding it difficult to get the required approval, it will be good for all the residents to come together and approach the authorities to convey your problem. With a great number of residents making a complaint, you stand a good chance of your problem being redressed. Usually, you can hope to get a positive response or at least a temporary solution to the problem by way of getting permission to install booster pump, enabling you to get water at a higher pressure. In the meanwhile, you can expect the municipal authorities to overhaul the existing pipeline.

Using Liquid Ring Vacuum Pumps And Booster Blowers

A liquid ring vacuum pump needs to be considered seriously if the gas load is wet. Its internal construction is designed for pumping of saturated loads without any apprehension of damaging the pump. In fact, a much increased pumping can be achieved from the standard pumping curve as the warm process vapors condense inside the cooler liquid ring.

This is not the case if oil sealed or dry vacuum pumps are used for pumping wet gases and should seldom be thought of for this kind of service. However, the liquid ring vacuum pump relies on the physical characteristics of the sealant to decide its utmost vacuum level and is generally restricted to about 25mmHg.

For achieving deeper vacuum levels an extra pumping stage like a rotary booster or blower can be used. Incorporating a rotary booster at the vacuum pump suction could increase the operating pressure by 4-10mm. The improved performance would usually deliver a more cost effective system, compared to using additional or bigger primary vacuum pumps.

A booster blower is backed by a liquid ring, and two of its interlocking rotors are used to trap and convey gas. The rotors synchronized by external gears rotate in opposite directions. Each rotor collects a predefined amount of gas on moving past the inlet port. The collected gas is transferred to the periphery of the casing bordered by the casing and the rotor. The gas continues moving at a steady pressure while actual compression takes place when it gets discharged from the discharge port. The lobes are synchronized by timing gears which maintain a steady clearance between the rotors and the cylinder.

The back gassing of a blower is totally decided by these clearances. There are no sealing or lubricating fluids in the pumping chamber of boosters. They have separate lubricating fluid reservoirs located at each end of the cylinder that continue to lubricate to its seals, bearings, and timing gears. Usually, a maze of seals is employed to separate the oil reservoir from the pumping chamber. Generally, rotating speeds are high-of the order of 3 to 4000 rpm and are made of different materials to suit the kind of gas used for the process.

As complete compression takes place at the discharge port of the blower, there is hardly any chance for the compressed gas to transfer its heat to the blower housing. Therefore, generally blowers have limited compression ratio. Normal theoretical limit for gas discharge pressures of more than 10mm is 2.3:1. Higher compression ratios will cause the discharge nozzle get overheated. As a result it transfers too much heat to the blower lobes which could result to mechanical failure.

Even when a water pressure pump operates at a compression ratio of only 2.3:1 above 10mm, there is a great advantage to pumping below 10mm because when the pressure goes lower the compression ratio in the blower can be as high as 50:1. That means you can have a pumping system of a larger capacity by adding a blower to a smaller vacuum pump. And, when applied to a liquid ring, vacuum pump allows the system pressure to become lower than the vapor pressure constraint of the liquid ring.

Calculating the temperature rise across the booster blower is relatively simple and straight forward. From atmospheric to pressures down to 10mm the temperature rise coefficient is essentially unity. With the pressure moving lower, say .1mm, the temperature rise coefficient attains a very low value, usually .01.

Temperature Rise = T x TRC x (K-1)/ (K) x (SR-1)/Volumetric Efficiency

Where T = Absolute temperature of the inlet gas

TRC = Temperature rise coefficient

SR = Staging ratio

For example, a blower working at 10mm with a 2:1 staging ratio and an inlet gas temperature of 100f would deliver a temperature rise of 90f. On our changing the staging ratio to 3:1 it would cause a temperature rise of 180f. And when we bring the operating inlet pressure to 1mm the temperature rise becomes 24f.
