GOOD-LUCK OF BEGINNING !
Solenoid valve selection should first follow the four principles of safety, reliability, applicability, economy, followed by six aspects of the field conditions (namely, pipeline parameters, fluid parameters, pressure parameters, electrical parameters, mode of action, special requirements to choose).
Selection basis:
First, according to the pipeline parameters to select solenoid valve: diameter specification (i.e.), interface mode according to the field pipe diameter size or flow requirements to determine the size of diameter 0.Interface mode, general > to choose flange interface,< can be freely selected according to user needs.
Second, according to the fluid parameters of the solenoid valve: material, temperature groupCorrosive fluid: should choose corrosion resistant solenoid valve and all stainless steel; Edible ultra-clean fluid: food grade stainless steel solenoid valve should be selected.High temperature fluid: the solenoid valve made of high temperature resistant electrical materials and sealing materials should be selected, and the type of piston structure should be selected.Liquid state: large to gaseous, liquid or mixed state, especially when the diameter is larger than the order must be distinguished., fluid viscosity: usually in the following can be arbitrarily selected, if more than this value, to choose high viscosity solenoid valve.
Third, according to the pressure parameters to choose the solenoid valve: principle and structure varietiesNominal pressure: this parameter and other general valve meaning is the same, is based on the nominal pressure of the pipelineWorking pressure: if the working pressure is low, it must choose direct motion or step by step direct motion principle; When the minimum working pressure difference is above, direct acting type, step by step direct acting type and pilot type can be selected.
Fourth, electrical selection: voltage specifications should be preferred as far as possible, more convenient.
Fifth, according to the length of continuous working time to choose: normally closed, normally open, or sustainable electricityWhen the solenoid valve needs to open for a long time, and the continuous time is more than the closing time should be used normally open.If the open time is short or open and close time is not much, then choose normally closed type.However, some working conditions for safety protection, such as furnace and kiln flame monitoring, can not choose normally open, should choose long-term electrified type
Sixth, according to the environmental requirements to select auxiliary functions: explosion-proof, check, manual, waterproof fog, water spray, diving explosive environment: the corresponding explosion-proof solenoid valve must be selectedWhen there is a backflow of fluid in the tube, the solenoid valve with check function can be selected.When you need to manually operate the solenoid valve on site, you can choose the solenoid valve with manual function.Open air installation or dust more occasions should choose waterproof, dustproof varieties (protection grade above).
Pneumatic fittings are required in any kind of pressurised gas system to link together sections of tubing, pipe or hose. They typically have tighter seals and are subject to lower pressure than hydraulic fittings, and are frequently found in pneumatic instrumentation and logic control systems, as well as moving parts such as cylinders.
Although fittings may represent the minutiae of the overall pneumatic system design, they are perhaps the most important of all the elements. Pneumatic fittings, together with their pipes, hoses and tubes, connect all the other major components together, and can therefore have a major influence on the efficiency, safety and energy consumption of the entire system.
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.
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. Before installation, the connecting pipe should be blown out completely, and impurities such as dust, chips and fragments of sealing strip should not be brought into the cylinder valve. In places where is with more dust, water drops and oil drops, telescopic protective cover should be installed on the side of the rod, to avoid the rod twisting during the installation. strong dust rings or waterproof cylinders should be used when telescopic sleeves are not available.
Standard cylinders should not be used in corrosive fogs or in fogs that inflates seal rings. The grease lubricating cylinder should be equipped with reasonable lubricator flow, do not lubricate the cylinder with oil, because the cylinder is filled with grease in advance, which can be used for a long time. This type of cylinder can also be supplied with oil, but once the oil is supplied, it cannot be stopped because the pre-lubricated grease may have been flushed away and insufficient oil supply will cause cylinder failure.
The installation position of the cylinder should prevent drilling cuttings from mixing into the air inlet of the cylinder. Cylinders should not be used as liquefied gas cylinders to avoid oil leakage. The sliding parts of the cylinder and the piston rod shall not be damaged to avoid air leakage and damage to the piston rod seal ring caused by improper operation of the cylinder. Compensating valve should have enough space for maintenance and adjustment, electromagnetic switch should have enough space for installation and adjustment. If the cylinder is not used for a long time, it should be operated once a month and protected with oil to prevent rust.
