Sprinkler Valve Solenoid- Manufacturers Suppliers Factory From China

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.

1. There are two ways of filter drainage: differential pressure drainage and manual drainage.  Manual drainage must be discharged before the water level reaches the level below the filter element.

2. When adjusting the pressure, please pull up and rotate the knob before turning it, and press the knob for positioning.  Rotate the knob to the right to increase the outlet pressure, rotate to the left to lower the outlet pressure.  Pressure adjustment should be gradually and evenly adjusted to the required pressure value, should not be adjusted in one step.

3, the use of oil feeder: oil feeder using JIS K2213 oil (ISO Vg32 or the same oil).  Please fill no more than eight full cups.  The number 0 indicates the minimum amount of oil and 9 indicates the maximum amount of oil.  Cannot rotate from position 9-0, must rotate clockwise.  A. According to the pipe diameter, flow size, pressure regulation, filtration accuracy and other technical performance parameters, select the air components needed by the system;  ?

B. The filter precision of air filter is 2um, 5um, 10um, 20um, 40um, 70um, 100um seven, according to the quality requirements of the air to choose the appropriate products;

C. When using the pressure reducing valve, try to avoid using the lower limit value of the pressure regulating range, choose the appropriate pressure reducing valve according to the requirements of the use of pressure;

D. Installation sequence: from the inlet end of the air source, connect the air filter, pressure reducing valve and oil mist at one time. The arrow direction on the component shell is the direction of air flow, and no reverse connection is allowed;

E. Air filter and oil mist must be installed vertically with the cup side down;

F. Once the oil mist is countercurrent, it will cause damage and danger to the internal parts, so it should be avoided;

G. During installation and connection, do not mix any impurities such as sealing tape and rust into the pipes.

Dear all friends and customer,

Happy Chinese New Year

We BLCH pneumatic Team

wish you lucky in the year of OX

safety & peace all the year round

Good health &Vitality

Flourishing wealth & fortune

we will come back from holiday after 20th Feb.  Thanks for your support in the new year!

Advantages of pneumatic components:  

1. Pneumatic device is simple in structure, light and easy to install and maintain.  The medium is air, which is not easy to burn compared with the hydraulic medium, so it is safe to use.  

2, the working medium is inexhaustible air, air itself does not cost money.  Exhaust treatment is simple, no pollution to the environment, low cost.  

3. It is very easy to adjust the output force and the working speed.  The speed of the cylinder is generally less than 1M/S, which is faster than the speed of the hydraulic and electrical modes.  

4, high reliability, long service life.  The service life of effective action of electrical components is about one million times, and the life of the general solenoid valve is more than 30 million times, some good quality valves more than 200 million times.  

5, air compressibility can store energy, to achieve centralized air supply.  The energy can be released in a short time to obtain a high speed response in intermittent motion.  It can be buffered.  Strong adaptability to impact load and overload.  Under certain conditions, the pneumatic device can be self-sustaining.  

6, full pneumatic control is with fireproof, explosion-proof, moisture-proof ability.  Compared with hydraulic mode, pneumatic mode can be used in high temperature occasions.  

7, because the air flow loss is small, compressed air can be centralized supply, long-distance transportation.

Disadvantages of pneumatic components  

1, because the air has compressibility, the speed of the cylinder is subject to changes in load.  This defect can be overcome by gas-liquid linkage.  

2. When the cylinder is moving at low speed, the low speed stability of the cylinder is not as good as that of the hydraulic cylinder due to the large proportion of friction in the thrust.  

3, although in many applications, the output force of the cylinder can meet the work requirements, but its output force is smaller than the hydraulic cylinder.  

Warm congratulations to BLCH Pneumatic, for the success of 350kWp distributed photovoltaic power generation project test.

Pneumatics are used in many of today’s industrial and automation environments, and there is an increasingly wide range of options from which to choose your components. Knowing how to choose pneumatic fittings is therefore all about suiting the materials to the job and its environment. In order to break down this process, you first need to identify:

• the specific environment in which your equipment will be working

• the required air pressure or PSI specification of your equipment

• any approvals that may be needed for the equipment and its components

• the material(s) from which your fittings should be made

• the type and size of tubing you will require

• the type and size of thread your fittings will need

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.
