    What is a Hydraulic Intensifier?

    A hydraulic intensifier system is quite simple in principle, the system uses hydraulic power to increase the pressure of a liquid or gas. Pressure multiplication occurs because of the dissimilar areas between the hydraulic piston and the process media piston. The ratio of the area between the hydraulic piston and process media piston is known as the pressure ratio.

    (Ex: a 10in³ hydraulic piston pushing a 5in³ process media piston had a ratio of 1:2). A ratio of 1:2 can multiply the process media pressure by two times the hydraulic pressure.

    Single Stage Intensifier

    With a single stage intensifier both the left and right sides have the same ratio resulting in one pressure discharge from the intensifier for every stroke as shown in the picture.

    Single Stage Intensifier

     

    Two Stage Intensifier

    With a two-stage intensifier the left and right sides have different pressure ratios, this is also known as a multiple ratio intensifier. Multiple ratio intensifiers allow for a larger pressure multiplication than with a single stage. This style of intensifier only produces a pressure discharge every other stroke as shown in the picture.

    Two Stage Intensifier

    What’s New?

    Maxpro Technologies has recently designed a new generation of intensifiers to seamlessly integrate with modern and advancing technologies. Our intensifiers now have the option of using electronics and integration to bridge the gap of the mechanical and digital world.

    With our latest generation of intensifiers, we are now able to have real time monitoring and feedback of all machine parameters right at your fingertips. For example, the machine is constantly analyzing inlet pressure, outlet pressure, hydraulic flow rate and temperature, coolant flow rates and so much more.

    You might wonder why it is so important to continuously analyze all this data, after all our previous generation did not do this. The reason is simple, More Control – More Efficient – Endless Possibilities.

    Maxpro Technologies Hydraulic Intensifiers

    More Control

    Our automated intensifiers with process monitoring have user programmable recipes to keep your process on point. Minimum and maximum process media pressures can be defined along with specific flow rates to dial in your process like never before.

    More Efficient

    In today’s world manufacturing is about being lean. Companies are constantly striving to increase productivity while simultaneously decreasing process waste. In the case of our intensifier, we were able to significantly reduce electrical waste. Running motors can be expensive especially under high load. Our control and monitoring system gives you on demand power when you need it and idles without load or powers down when not in use.

    Endless Possibilities

    No one knows your process better than you; this is why our system is programmed to be flexible. Recipes allow the user to have different process setups saved in the controller, all of which are continuously monitored to keep everything running safely.

    In modern times people are accustomed to being connected to their devices. Our latest intensifier is set up to be no different. Our controls system can remotely interface where an internet connection is available as well as receive email notifications of critical machine events. An auxiliary plug prewired to be integrated with other pieces of equipment is also included.

    Can You Benefit from an Intensifier?

    Hydraulic Intensifiers can be used any time the available liquids or gases are at pressures lower than what is required by the process. Intensifiers will take low pressure liquid or gas and boost them to a specific pressure and flow rate depending on the intensifier configuration and horsepower. Some common pumping media and applications are as follows.

    Common liquids

    • Carbon Dioxide
    • Water
    • Oil

    Common Gasses

    • Nitrogen
    • Carbon Dioxide
    • Hydrogen
    • Dry Air
    • Helium
    • Argon

    Industry Applications

    • Gas Foaming of Polystyrene
    • Gas Cylinder Filling
    • Supercritical CO2 Extraction & Cleaning
    • Gas Assisted Injection Molding
    • Gas Supply to Sintering Furnace
    • Burst Testing
    • Gas Tube Trailer & Cylinder Scavenging
    • Gas Vapor Reclaim from Cryogenic Storage
    • Supply Gas to Hot Isostatic Pressing (HIP)
    • Cold Isostatic Pressing (CIP) of powdered metals and ceramics
    • Hydrostatic pressure testing

    Engineered Solutions

    Maxpro Technologies offers three system levels;  manual, control and monitoring, and also control and monitoring with tubing.

    Manual

    Manual systems are the simplest form of the hydraulic intensifier. These systems consist of the intensifier, hydraulic power unit and a motor starter with on/off control. This style of system must either be manually operated or integrated into other equipment due to the absence of process feedback. This is a great style of system for someone who wants to do all their own integration and controls or wants a budget system to operate manually.

    Manual Instensifier

    Control and Monitoring

    The control and monitoring system is a plug and play system recently designed to fill a rapidly increasing market demand. This style of Intensifier is a closed loop system meaning it constantly watches your upstream and downstream processes and makes decisions on how to operate based on that data. The advantage of this style of system is that it takes all the guess work out. The integrated recipe page allows you to set up custom process parameters that the system can safely operate within.

    Control and Monitoring with Tubing

    Systems that incorporate the addition of external plumbing are turnkey systems. These systems not only control the intensifier as described in the control and monitoring system, but they also control any upstream and downstream plumbing as specified by the customer. At Maxpro, our engineers and designers are dedicated to designing custom systems to your specifications.

  2. Product Spotlight: Maxpro’s High Pressure Relief Valves

    Leave a Comment

    Pressure relief valves are intended to protect system components from over pressurization. The pressure relief valve is often set at 10% over maximum system operating pressure to allow the system to operate up to the maximum working pressure rating. The maximum allowable working pressure for the system is based on the lowest rated system component. The size must be chosen to allow the rate of relief flow to equal or exceed the potential various sources of over pressurization. Materials of construction must be chosen to be compatible with the fluid or gas that will be encountered. Poor material choices could lead to faulty operation of the relief valve and failure to relieve overpressure as intended.

    Features of MAXPRO®’s High Pressure Relief Valves

    High Pressure Relief Valves

    Proportional high pressure relief valves from MAXPRO® are designed with simplicity in mind. The goal is to support long term reliability, performance, and serviceability, while providing the safety relief valve function. The relieving function is accomplished by an adjustable spring force acting upon a stem that presents two unequal areas for inlet pressure to act upon, causing stem lift off the seat. The higher the spring force, the higher the relieving pressure. With the proportional relief valve design, higher system pressure causes higher stem lift, resulting in higher relieving flow. This “unbalanced stem” design also provides for smoother operation over those that simply lift from the stem area under the seat and minimizes the reseating pressure window as well as hysteresis of the set pressure. These valves are not poppet style relief valves. At a preset pressure, poppet style relief valves “pop” full open for maximum flow, and then snap closed at some reseating pressure. Poppet style valves tend to be more complex to achieve the pop-open action.

    MAXPRO® offers proportional relief valves with four minimum/maximum set pressures to support most applications. Choose from:

    Note: The sensing pressure enters the side port and exits the bottom port. MT3RV and MT10RV have two standard side ports. The second port can be for a tee for a gauge or vent line, or the extra side port can be plugged if preferred. MT25RV and MT66RV have one sensing port.

  3. How to Choose the Right High Pressure Valve for Your Application

    Leave a Comment

    MAXIMATOR high pressure valves are designed to safely operate at pressures of 15,500 psi for a 1-½” medium pressure valve up to 101,000 psi for an Ultra-High Pressure Valve. High pressure valves are used to regulate flow in various fluid handling operations across a wide range of industries, including aerospace, automotive, military, and mining industries. Selecting the best, high pressure valve for your application is crucial.

    There are many factors to consider when choosing a high pressure valve. Below, we highlight some key factors to consider when choosing the right high pressure valve for your application.

    Factors to Consider When Evaluating Your High Pressure Valve Needs

    Important factors to consider when evaluating whether a particular high pressure valve is right for your fluid handling application include:

    • Process medium: The valve should be able to handle the process medium, whether it is in gas, liquid, or steam form, inert, abrasive, or corrosive, and hot or cold.
    • Pressure rating: It should be rated to handle the range of pressures expected in operation. Consider upstream and downstream pressure for the maximum, normal, and minimum flow rates.
    • Temperature: The valve should be rated to handle process medium temperatures.
    • Flow rate: A high pressure valve should be properly sized to ensure it has the proper flow rate capacity.
    • Connection type and size: It should have a connection type and size that fits the inlet/outlet piping.
    • Valve style: Do you need a manual valve or an air actuated valve? If air operated, should the valve be air-to-open (normally closed) or air-to-close (normally open)?
    • Construction material: A high pressure valve should be constructed of material that can withstand the process medium and operating conditions (temperature, pressure, flow, etc.). For example, stainless steel is suitable for fluid handling operations involving corrosive materials.
    • Application: It should be appropriate for implementation in the system.

    High-Pressure Valve Solutions at MAXPRO®

    At MAXPRO® Technologies, our MAXIMATOR® line encompasses a range of manual and air-actuated valves. Key features include:

    • Non-rotating, rising stem design
    • 316 stainless steel wetted parts with 17-4 PH stainless steel stem
    • Metal-to-metal seating for bubble-tight shut-off

  4. Factors Involved in Air Amplifier Design

    Leave a Comment

    Air amplifiers are industrial equipment designed to increase air pressure to improve pneumatic tool operation.  When centralized air pressure systems are insufficient to power air-driven tools, air amplifiers can fill localized demand. Depending on the type of unit, air amplifiers have various pressure and flow capabilities, ranging anywhere from 30 to 4,350 PSI. Because there is such a wide selection of air amplifier designs available on the market, it is important to carefully select the right one for your intended application.

    Air Amplifiers

    How Air Amplifiers Work

    Air-driven air amplifiers use the principle of differential areas to generate pressure. By having a higher ratio of inlet to outlet piston areas, air amplifiers utilize shop air, use some of that air as power to operate the unit (called the ‘drive air’), and intensifies the remainder of the inlet air into pressurized output. Shop air utilizes a four-way spool valve to affect cycling, then exhausts the drive air.  There are two main ways MAXPRO® Air Amplifier Systems achieve this:

    1. DLA Series:  A large air piston drives a smaller air piston to generate higher pressure levels.
    2. PLV Series:  These units have two fixed area pistons.  During cycling, the air amplifier utilizes one of the pistons to effectively double the incoming air pressure.

    MAXPRO® air amplifier systems include an air control package, the amplifier, air storage tank with drain valve, pressure relief valve and outlet pressure regulator with gauge.

    Sizing Air Amplifiers

    Consider these factors as you determine the right air amplifier for your application:

    Airflow

    Airflow demands are based on the application, environment, and specific equipment involved in each case.  Parameters to consider:

    • Available inlet air drive flow and pressure
    • Required outlet pressure
    • Required flow at outlet pressure

    Applications Requirements

    • What is the highest flow and pressure needed?
    • Describe typical machine cycle requirements

    Pressure

    It is crucial to figure out the highest and lowest air pressure requirement.  Remember you will need to store up higher pressure than is needed to provide the delta P needed for airflow.

    Other Considerations

    • Duty Cycle (Intermittent demand or 24/7 operation?)
    • Environment (hot, cold, inside, outside, clean, dirty?)
    • Future expansion of production line (will more volume be needed in the future?)
    • Future need for higher pressure and flow?
    • Distance to work (line lengths can become a factor for pressure and flow)
