  • Troubleshooting Common Pressure Problems

    One of the common misconceptions about air compressors is that they somehow manufacture pressure. In fact, compressors only pump air in a system that creates back pressure against which the compressor pumps. When the pressure is higher than necessary, it creates wasted energy in the system, which means inefficient performance and higher operating costs. Low system pressure can also affect performance at both the supply side and demand side of an air compressor system. For these reasons, it’s important that you learn how to troubleshoot pressure problems you experience in your air compressor system. If the problem persists or you are unable to identify its cause, contact an air compressor repair company in San Jose .

    Determine Which Applications are Driving System Pressure

    If you are experiencing consistent pressure problems in your compressed air system, the first step should be to determine which applications are the most sensitive to pressure fluctuations, which in turn are most likely to be driving changes in system pressure. Depending on the size of your operation and whether or not you have a dedicated compressor operator, you may need to contact an air compressor repair company to determine which components should be inspected first.

    Look for Pressure Drops at Point-of-Use Components

    If you cannot determine which applications are specifically driving system pressure changes, look for pressure drops at the point-of-use components within your air compressor system—i.e., the filter, regulator, lubricator, and final hoses. Installing delta pressure measuring instruments at these components can help you identify pressure changes and thus identify where to focus your repair/adjustment efforts.

    Schedule Professional System Inspection

    Unless you have a dedicated in-house air compressor operations team, the fastest and easiest way to troubleshoot pressure fluctuations within your air compressor system is to schedule a professional inspection with an air compressor repair company in San Jose. These experts can quickly identify the cause of your pressure issues and make the necessary repairs, adjustments, or retrofits to get your air compressor system back up and running in no time.

  • Selecting the Right Air Compressor Oil

    Oil changes are just as important for air compressors as they are for vehicles, generators, and any other pieces of equipment that need oil for internal lubrication. And like those other pieces of equipment that require oil, it’s important that you use the right type of oil inside your air compressor to achieve maximum performance, efficiency, and protection. If you or someone within your business handles air compressor maintenance, watch this video to learn how to select the right type of air compressor oil.

    If you have any questions about air compressor oil or would like to outsource the maintenance of your air compressor, including oil changes, contact an air compressor maintenance and repair company in San Jose. Air compressor service providers in the Bay Area offer periodic or monthly maintenance programs that take the guesswork out of maintaining your air compressor system and ensure that you experience as few problems and the best performance possible.

  • Preventative Maintenance for Your Air Compressor System

    Whether you have a small electric air compressor or a complex industrial-grade rotary screw air compressor, routine maintenance can save you a lot of time and money in the long run. For starters, routine maintenance will ensure that your air compressor system runs as efficiently as possible, which means lower operating costs over the life of your air compressor. Routine maintenance can also prevent major air compressor repairs and even extend the life of the system, which means you won’t have to invest in a replacement air compressor for some time. Here’s a few tips to help you create a preventative maintenance plan for your air compressor system, whether you handle the maintenance or hire an air compressor service company in San Jose to perform the maintenance on your behalf.

    Consider Size of Air Compressor System

    First and foremost, you should know that different sized air compressor systems require different approaches to preventative maintenance. Although all air compressors can benefit from routine preventative maintenance, larger and more complex systems obviously require a greater deal of maintenance at more frequent intervals than a small air compressor or even portable air compressor system. Keep this in mind as you create a preventative maintenance plan for your compressed air system.

    Refer to Manufacturer’s Maintenance Specifications

    To take the guesswork out of creating a preventative maintenance plan that’s appropriate for your air compressor system, refer to the manufacturer’s maintenance specifications. However, it’s important to keep in mind that manufacturer-recommended maintenance intervals and plans are intended primarily to protect the equipment from failure rather than optimize the system. For this reason, you may want to perform maintenance more frequently to increase the efficiency of your air compressor system.

    Assign Maintenance Roles and Responsibilities

    Depending on the size of your business and the size of your air compressor system, you may want to assign specific maintenance roles and responsibilities to different people on your team who interact with the air compressor system on a regular basis. For example, one person may be responsible for logging system pressure and power at the end of each shift, while someone else may be responsible for oil and filter changes according to manufacturer-recommended service intervals.

  • A Look at Air Compressor Retrofitting

    If your business has outgrown your existing air compressor system, you have two options: invest in a brand-new air compressor setup or retrofit your existing system to meet your current and future needs. Depending on the size and complexity of your existing system, a retrofit may be more cost-effective than installing a brand-new air compressor system. Retrofitting your existing air compressor system requires a complete evaluation of your system, including both the supply and demand sides and all of the individual components. The main goals of an air compressor retrofit are to increase reliability, increase performance, decrease maintenance, and decrease the operating costs of the compressed air system while maintaining quality.

    Evaluating your air compressor system and designing a retrofit plan requires representatives from your energy utility (gas or electric) and a compressed air systems supplier in San Jose . Utility representatives and air compressor experts will work together to identify equipment upgrades, pressure control changes, and supply/demand side retrofits that will improve your current air compressor system to meet your current and expected future needs.

  • How Pressure Affects the Performance of a Rotary Screw Compressor

    Rotary screw air compressors deliver quiet and vibration-free performance, and when sized correctly by an air compressor supplier in San Jose they can also be among some of the most effective and energy-efficient air compressors on the market today. Whether you’re looking for an industrial air compressor for a giant manufacturing operation or a smaller commercial air compressor for an auto body shop, a rotary air compressor might be the right solution. As you do your research and weigh the different factors and considerations that go into selecting an air compressor for your business, keep in mind how pressure affects the performance of rotary screw air compressors.

    Torque and Discharge Pressure

    The torque required to turn the rotors inside the air compressor is a function of the pressure pushing against the rotors, which means the torque require to move a given volume of air through the compressor is reduced as the discharge pressure is reduced. In general, the air compressor industry estimates approximately a 0.5 percent drop in power for every 1 psi reduction in discharge pressure .

    Internal Friction Loss

    Pressure at the discharge of the compressor also includes pressure losses across internal components causes by friction and heat. For oil-flooded rotary screw compressors, air goes through internal piping, an oil separator element, baffles, check valves, heat exchangers, and a moisture separator before being discharged. The influence of internal friction loss on pressure changes within the air compressor can affect torque, power, efficiency, and performance.

    Power Factor Value

    The math required for calculating power relative to discharge pressure for a specific air compressor system (which in turn yields insights regarding efficiency and output) is very complex, but the change in power associated with a reduction in pressure follows a general rule: as the power factor value becomes lower, the amperage will increase. However, because power factor values and voltage can change independent of the compressor operation, measuring amperage only can lead to incorrect assumptions regarding performance and efficiency.

  • How to Choose and Air Compressor and Pneumatic Tools

    Whether you’re an avid do-it-yourselfer, a residential contractor, or anyone else in any other industry that would like to get work done faster and easier, pneumatic tools can take your productivity levels to new heights. If you’ve never used pneumatic tools before or have only used pneumatic tools selected by others, you might not know the first thing about choosing the right tools and, more importantly, the right air compressor system to power those tools. This video offers great tips and advice for anyone interested in purchasing their own air compressor and pneumatic tools.

    Although these tips are certainly a step in the right direction, your best bet is to consult with an air compressor company in San Jose to find the right setup for your needs. An air compressor supplier will be able to recommend the best size and type of air compressor based on the pneumatic tools you will be using, the environment in which you work, and other factors that can affect your air compressor system.

  • A Look at Air Compressor Audits in Chemical Plants

    Considering the greater emphasis on safety, process stability, and system reliability within the chemical and petrochemical manufacturing industries, it’s no surprise that air compressor audits take on a more serious role in chemical plants than in other commercial or industrial settings. More than simply revealing when you need to seek air compressor repair in San Jose , regular air compressor audits can also enhance system reliability and reduce operating costs. Here are some important things you should know about air compressor audits in chemical plants.

    Long Pipe Runs and Multiple Compressor Rooms

    Auditing a compressed air distribution system in a chemical manufacturing facility is different than other industries for many reasons. For one, pressure drops can be an issue due to the typically extreme length of pipe runs, especially in remote areas of the plant. Some facilities get around this by having multiple compressor rooms, which can also be a challenge to audit considering how difficult it is to coordinate the behavior of systems with multiple entry points.

    Demand and Supply Side Audits

    Auditing the demand and supply side of the air compressor system inside a chemical plant first requires identifying the primary goal of the audit. For example, if increased reliability is the primary goal, the audit will look for areas of improvement or upgrades that will result in more repeatable performance of demand and supply control valves. Similarly, the goal of the air compressor audit may be to reduce operating costs.

    Air Compressor Improvements

    Although auditing chemical plants is a challenge, and an investment, the potential return can be massive in terms of performance, reliability, and operating costs. Having as wide a view of an air compressor system as possible will allow an auditor to recommend areas where air compressor systems, processes, and/or components can be improved. For example, one common application in chemical facilities that often has a great potential for improvement is air sparging, in which compressed air is fed into a tank to reduce the concentrations of VOCs within the container.
