When working on any air conditioning system, the ability to pull a hard vacuum to remove all moisture from the system is critical. One of the best tools available to the A/C technician is the Robinair 15600 two-stage vacuum pump. This article will take a look at why this AC pump is so useful, and will end by showing you where you can save a lot of money if you want to buy a new Robinair 15600.

Why We Need an A/C Vacuum Pump

Our main goal in A/C service is to ensure that all air and water have been removed from the system before it is recharged with fresh refrigerant and the appropriate amount of lubricant. Water and air are enemies of cooling efficiency. Both are very difficult for the compressor to actually compress, leading to flow restrictions in the system. Water threatens to freeze up the evaporator core and reacts corrosively with the refrigerant charge, leading to expensive and difficult repairs. On many cars, replacing an evaporator core is a nightmare, requiring many hours of labor to remove the dash for access.

To remove water from an A/C system, we reduce the pressure in the system, thereby reducing the temperature at which water boils. At sea level, water boils at 212 F, but if we pull a vacuum of 29.40 in/Hg that boiling point falls to only 60 F. And if you can pull 29.86 in/Hg, water will boil off at a mere 10 F. It always helps to do this job on a warm day with the car's cabin heated thoroughly by leaving the windows closed. But there's no substitute for a really good vacuum pump.

Why the Robinair 15600 Two-Stage Pump is Superior

The Robinair 15600 is very powerful, pulling a super-hard vacuum in under 60 minutes. The cheap venturi-style pumps can never come close to this kind of performance. In most cases, a venturi pump will not fully evacuate the system, and that means performance and reliability problems down the road. As an electric pump, it's much quieter than running an air compressor for a venturi pump. This is much appreciated if you're working in a confined shop, or you like to be considerate to your neighbors at home. Either way, it's nice to be able to hear yourself think! It's easy to take to different job sites because you only need one piece of equipment. There's no need to lug an air compressor around with you. As a two-stage pump, there is no risk that the system you're working on will be contaminated by pump oil. This design also contributes to the strength of the pump. With a huge 6 cfm capacity, the Robinair 15600 can handle larger applications if necessary, such as RVs or commercial vehicles. This is a pump that can handle just about anything for years to come.

How Does a Sump Pump Work?

!: How Does a Sump Pump Work?

Many of us may have a difficult time with getting water in our basement, either as a result of rainwater entering in through the walls or perhaps even because our basement resides below the water table. If this is the case, one of the only solutions for you is to install a sump pump. Since there are so many different ways in which this can be done, it leaves a person wondering, how does a sump pump work?

A sump pump is a relatively simple machine to understand. It generally has a ball attached to it that floats on top of any water that is located within the sump hole. As the water level rises, the ball rises as well and eventually, it will trigger a mechanism that will cause the pump to come on automatically and push the water outside. As the water level lowers, and the ball lowers beyond a certain extent, the mechanism will be triggered again in order to shut the pump off.

It is generally not necessary for you to understand how a sump pump works because once they are installed, they are relatively problem-free. As a matter of fact, it would really only be if a problem was occurring with the pump that you would ask the question, how does a sump pump work? If that is the case, either a minor adjustment in the float may be in order or it may be necessary for you to install a new one. Fortunately, they are not a very expensive item to purchase.

Submersible Solar Powered Water Pumps

!: Submersible Solar Powered Water Pumps

If you are facing acute power shortage and is in need of regular, consistent supply of water for irrigating your farm, then perhaps the best solution for your problem would be a Solar Submersible Pump. Widely regarded as the most cost-effective and economical of all water pumps, the Solar Submersible pump is mainly used in well pumping applications. They offer several distinct advantages over other water pumps. Solar Submersible pumps could be positioned in a pond or creek in such a way that they remain fully submerged and are basically used in pressurized and non-pressurized irrigation, home water systems and livestock watering.

A Submersible Solar Powered Water Pump offers a tremendous deal of benefits. If your water system is equipped with a battery bank which facilitates energy storage, then water could be pumped at any time of the day, in all weather conditions. A solar-powered water system basically constitutes two parts. The main component of a solar powered water system is the solar electric modules. The motor and pump operates using the electricity from the solar panels. The water is thus directed through the pipe to the desired place. Most of the solar-powered water systems pump the water into a reservoir, where abundant water is stored and supplied for immediate use in cloudy weather or at night.

Moreover, a Solar Submersible Pump needs very little maintenance. Installing the equipment is also very easy and could be set up even by a person who has very little technical know-how or expertise. They are generally installed on special ground or pole mounting structures. One of the greatest advantages of using solar electricity is that it could be used directly or it could be conveniently stored in batteries for future use. The batteries used in most solar powered water systems are called deep-cycle batteries and could be recharged whenever necessary. They also provide a consistent supply of power over a longer duration of time. And what more...! Using solar power to pump water is highly cost-effective and reliable, with a submersible pump and solar cell panel available for less than Rs. 70,000.
