Air Lubricator In Pneumatic System- China Factory Suppliers Manufacturers

Description of filter working principle:

The compressed air from the inlet is strongly rotated through the tangential gap of the guide plate. The liquid oil, water and solid pollutants are thrown to the inner wall of the cup by centrifugal force, then flow to the bottom.

The compressed air has removed the liquid oil, water and large particle impurities, and further removes the small particles through the filter element, then flows out from the outlet.

The baffle prevents the liquid oil and water below from being swept back into the airstream. The condensed water accumulated in the cup can be discharged from the drain by pressing the manual button.

You may still will encounter many problems in the actual use process, even fully understanding the working principle.

TIPS1: replace the filter element in time

When the pressure difference between the air inlet and the air outlet is greater than 0.1MPa, or the service time is more than 2 years. Be sure to replace the filter element!

Tips 2: Distinguish between normally open and normally closed drains

There are automatic drain and manual drain, normally people prefer automatic drain. There are two kinds of drainage specifications for automatic drainage: normally open and normally closed.

But normally open is not equal to normally leaky

Tips 3: Installation required

Pre-blow before assembling, to prevent debris, dust, and sealing materials mixed into the compressed air.

The inlet and outlet can not be installed in reverse. And filter need to be installed vertically, with cup downward and make space for maintenance.

The front section of the filter should be equipped with a choke valve for maintenance.

The drain pipe should be secured to prevent the discharge speed from being too fast during the drainage process, which may cause the pipe to swing and injure people.

Tips 4: Strengthen the maintenance

Check the cup regularly for cracks, to prevent cracking and hurting people.

Ordinary cup is made of carbonate polyester. It need to avoid being used with organic solvents and chemical fumes. If you have to, choose a nylon or metal cup. And metal cup is necessary at high temperature.

Avoid the sunshine when using it.

Cylinder Accessories

Even when a cylinder is sized properly, it may stroke too fast and require use of a flow control, typically by controlling flow of air leaving the cylinder. This also reduces noise problems caused by cylinders banging and reduces rapid exhaust racket. These flow controls are typically mounted directly to the cylinder, but can also be mounted inline near the cylinder, or at the valve if the hose between the valve and cylinder is less than about 3 feet.

Specifying cylinders with built-in cushions can help provide long-term performance in high-speed pneumatic motion applications. The cushions allow a cylinder to stroke at high speed and only slow down near the end of stroke for a quiet, low-impact stop. Adjustable pneumatic cushions are often the best solution, comprised of specially designed end caps with built-in flow controls. Mufflers can also be used to quiet cylinder or valve exhaust noise, and they are often a simple and low cost solution.

Cylinder position switches are extremely helpful in sequencing operations and prevent starting the stroke of one cylinder before the previous cylinder’s stroke is complete. Using timers to control a sequence instead of position sensors should be avoided in this and most cases. One stuck or slow cylinder during an automated sequence can cause a machine crash, costing much more than the cost of buying, installing and programming end-of-stroke sensors.

These are just a few of the many items to consider when designing a successful pneumatic system. Other factors, such as energy efficiency, can affect overall system design as well. But regardless of the design, watch out for the common issues and always be sure to supply, prep and distribute the air properly. When properly applied, your pneumatic devices and actuators will have a long life with limited operational issues along the way, and with minimal required maintenance.

Control Valves

Once the cylinders are selected, you should now have a good idea of the flow rate and pressure of compressed air needed. With this information, you can select control valves. Items to consider in valve selection are size (flow capacity), type and actuation method.

Choosing the right type of valve for the job required is not as difficult as it may seem. For cylinder control, the simplest method is to use a 3-way valve for a single-acting cylinder and a 4-way valve for a double-acting cylinder. Systems can be much more complex if needed, but let’s focus on a basic system for now. The form factor of the valve can vary a great deal and many people have a variety of preferences. It’s usually best to make sure the valve has the needed performance characteristics before locking into a particular form factor.

Valve Sizing

Once the function of the valve has been determined, look at the required flow capacity. The usual first step is to use the air cylinder bore, stroke and cycle rate to determine a flow rate in standard cubic feet per minute (SCFM). Many valve suppliers will list a flow rate at a particular inlet pressure and pressure drop. Others will list this value as a factor Cv, which has no units. For a more thorough explanation, check out our Interactive Cv Calculator here. A simple thing to remember is that a larger Cv value will allow a higher flow rate of air through the valve. Key points to remember in valve sizing are that undersized valves may restrict flow and not allow a system to work properly. Oversized valves often cost more and will use more air. Keep in mind that air consumption is a major portion of the expense for a pneumatic system. If air consumption is a major concern for your factory, check out our Interactive Air Consumption Calculator here.

Valve Actuation

How will the valves be operated? Manual valves could be push button, lever or foot pedal activated. The more common method is to use electric solenoids to operate the valve. Solenoids are available in a variety of both AC and DC voltage ratings to fit just about any need. Match the solenoids up with your electrical control system. In less common situations, an air piloted valve may be required. When air pressure is applied to a pilot port, the valve switches. This is a good way to switch very large valves while using very little electrical power – use a small solenoid valve to send air to the pilot port of the large valve.

Select the correct cylinder according to the following conditions:

1. According to the type of cylinder:

Choose the type of cylinder according to the working requirements and conditions.  Use a heat-resistant cylinder in a high temperature environment.  In a corrosive environment, the use of corrosion – resistant cylinder.  Install a dust cover on the protruding end of the piston rod in harsh environments such as dust.  When no pollution is required, the cylinder without oil or oil lubrication should be selected.

2, according to the size of the force:

According to the size of the load force to determine the cylinder output thrust and tension.  In general, the acting force of the cylinder required by the theoretical equilibrium condition of uniform external load is multiplied by the coefficient 1.5~2.0, so that the output force of the cylinder is slightly surplus.  The cylinder diameter is too small, the output force is not enough, but the cylinder diameter is too large, so that the equipment is cumbersome, the cost increases, and increases the consumption of gas, waste energy.  In the fixture design, should try to use the expansion mechanism, in order to reduce the cylinder size.

3. According to the stroke of the piston:

And the use of the occasion and the stroke of the mechanism, but generally do not choose full stroke, to prevent the piston and cylinder head collision.  If used for clamping machine structure, it should increase the allowance of 10~20mm according to the calculation required stroke.  It should be selected as standard trip as far as possible to ensure the supply speed and reduce the cost.

4. According to the movement speed of the piston:

Mainly depends on the cylinder input compressed air flow, cylinder inlet and exhaust port size and pipe diameter.  High speed motion is required.  The cylinder movement speed is generally 50~1000mm/s.  For high-speed motion of the cylinder, the intake pipe of large internal passage should be selected;  For the load changes, in order to get slow and steady speed, can choose with throttle device or gas-liquid damping cylinder, it is easier to achieve speed control.  When selecting throttle valve to control the cylinder speed, note that: when the horizontally installed cylinder pushes the load, it is recommended to use exhaust throttle speed regulation;  When vertically installed cylinders lift loads, it is recommended to use intake throttle speed regulation;  When the stroke is required to move smoothly to avoid impact, the cylinder with buffer device should be selected.

    Time is flying, in an instant, half a year of 2020 has passed. Enterprises and employees even all of the world have undergone a new test in the past six months due to the COVID-19.

    In the beginning of 2020, affected by the epidemic situation, the company’s commencement date has been postponed again and again. With the support and one month’s arduous straggle of company’s leaders, company finally started operation on 22 February successfully.

 

  In order to meet the supply needs of customers, we have been continuing to work overtime with quick respond to deliver high-quality products to customers.

The expert review meeting named “Internal Pilot Type Precision regulator” of Zhejiang manufacturing group standard, which was leading by our company successfully held in April.

Affected by the epidemic situation, the safety production monthly meeting of the company was held on May 4. But we have never relaxed our vigilance about safety in production.

On June 23, 2020, Ningbo Fenghua District pneumatic industry association youth branch held a salon activity in our company. We have exchanged many acknowledge with Yueqing and Fenghua’s ” HYDRAULIC-PNEUMATIC MAN” as well.


Even though the half year of 2020 is over, in the following six months, let’s keep going on with high enthusiasm for work.

WE PASS TOGETHER !

One of the important parts of the pneumatic components is the cylinder. In order to ensure the normal use of the cylinder and avoid unnecessary situations, for the use of the pneumatic components and cylinder, let’s check the right way to use cylinder. When using the cylinder, the air quality requirements are very high. Clean, dry compressed air should be used. The air should not contain organic solvents, synthetic oils, salts, corrosive gases, etc., in order to avoid bottle and valve failure.
