Uniweld presents 12CFM Hummvac Vacuum Pump - HVP12. The vacuum pump is a device that uses a vacuum to create pressure. It is used to produce low pressure in the fuel tanks of some aircraft. The design consists of a vacuum chamber containing a diaphragm, which is connected by a rod to the engine-driven suction fan. As the diaphragm moves, it opens and closes an air valve that controls the flow of air through the fuel tanks. The pumps are typically located at the front of each tank, and are either connected directly to the fuel feed or controlled by a valve in the tank's outlet pipe.
As you're probably well aware at this point, the vacuum pump is a machine used to create negative pressure. This means that the air inside the pump is under pressure from being sucked inward by the pump's fan blades and motor. Once that air is inside the pump, a valve closes and seals off the pump from outside air, so that air inside and outside of the pump is separated. Since there's a lower pressure on the interior of the pump, it's easier for gas molecules to diffuse through any porous materials that are acting as barriers between the two sides of the pump. This allows you to use your vacuum pump to suck out some of those pores, leaving your target object more compact and therefore stronger.
Vacuum pumps are used to remove air from a container. They can be used to create a vacuum in the space between two flat, sealed surfaces. The removal of air reduces the movement of material within the space, which is useful when it comes to transporting materials that could leak or shift during shipping. Vacuum pumps can also be used when filling a box with products. By creating a vacuum in the box, the items inside are pushed together and fill in the extra space. This helps keep the contents from shifting or being damaged during transit.

Uniweld presents Refrigeration Gauge HP Rd Pls - G29LD-5. A refrigerant gauge is a simple piece of equipment that can be used to test the levels of refrigerant in various HVAC systems. This allows the technician to ensure that no leaks exist before adding any new refrigerant to the system, avoiding evacuation and recharge requirements. The gauge is also used to show technicians whether or not they are low on refrigerant or if there is an overcharge of refrigerant within the system. A standard refrigerant gauge usually comes with a 0-3000 psi scale with a 100 psi increments, which makes it easy to measure any amount of pressure within the system.
In order for the technician to use a gauge, he or she must first know how to set up a leak test on the system. Using a copper tube with an end cap and a small amount of soapy water inside, the technician places one end of the copper tube into the soapy water and submerges it into one of the lines that are connected to the evaporator coil. If there is no leak present in this line, bubbles will begin to appear in only one area of the copper line. The technician then switches over to his or her gauging device and attaches it to this line where bubbles are not appearing.
A series of numbers and arrows on a circular dial indicate how much gas is inside the system: if there is too much gas—a condition known as overcharging—the arrow points upwards to indicate that more gas needs to be released. If there is not enough gas in the system, the arrow points downwards, indicating that more gas needs to be added. When both arrows are pointing upwards (or downwards), it means that there is an equal amount of gas at each port and that a compressor needs to be activated in order for cooling or heating to take place.

Uniweld presents Manifold LPF 3" HP Hose - QS4L3H-5. These gauges are devices that measure the amount of refrigerant or gas in a cooling system, such as the refrigerator in your kitchen or an air-conditioning unit that cools a room. In some cases, they also measure low- and high-pressure, a measurement of how much pressure the gas is under. The gauge measures this pressure with either digital or mechanical gauges.
Digital gauges have a digital readout of the pressure and can be used when troubleshooting issues such as leaks to help determine whether the leak is coming from inside or outside the system. Mechanical gauges are considered more accurate but require regular calibration to ensure they're working properly. The most common type is analog, which has a needle that rises and falls with changes in the pressure.
Manifold Gauge Sets usually include one or two temperature probes that attach to different parts of a system to ensure the temperature inside and outside of the unit remains at an appropriate level. They can be inserted into liquid lines, such as those on a heat pump, or into a suction line to measure how effectively it's pulling in coolant. These sets come in several sizes that fit different systems and will sometimes include multiple adapters to ensure compatibility with all kinds of plumbing systems. The manifold gauge, sometimes referred to as a HVAC gauge or a refrigeration gauge, is used to determine both low- and high-pressure readings for refrigerant systems. This type of gauge is useful for troubleshooting issues with refrigerators and other cooling systems, as well as for evacuating and recharging a system.
