Q:What do you mean, flange four?
The number of holes is a multiple of 4
Q:650 how big flanges and valves are used in the pipe?
You mean the inner diameter of the pipe is 650, then the butterfly valve or other valves and flanges are 650. If you have any further questions, you can continue to ask questions
Q:Why is the ultra short flange distance the advantage of a single camera?
The shorter the flange distance of a single camera, the better the edge quality.The flange distance refers to the distance between the mounting flange and the converging point of the incident lens parallel light, which is the distance from the fuselage lens to the sensor.Micro single flange distance is shorter and shorter, for example, just released Fuji X-pro 1 flange distance is only 17.7mm, compared to SONY E bayonet 18mm and Micro 4/3 system 20mm is shorter! Flange recall system SLR and paraxial distance, we will find that both the Nikon F, Canon EF or other Pentax K is about 45mm, the Leica M bayonet flange distance in 27.8mm, compared to the current micro single are very!SLR due to the presence of reflecting plate flange from natural than no reflector micro single and paraxial long, this is not what doubt, however you may have heard, paraxial edge quality generally better than the SLR, and micro single edge quality is better than the paraxial.In fact, the pinhole imaging principle and imaging camera lens can be seen as similar, cardboard and hole, and the sensor is wall, so it is not difficult to understand, when the camera sensor distance closer, the amount of light received on the central and edge closer to the sensor, so the quality is more close, this is also the reason why the micro single flange distance is small the better the quality of edge.
Q:PN40 valve flange surface using RF or FM?
PN40 valve flange surface default FM, and if you use RF, you must note.
Q:What is flange connection pile?
Classification of pilesWith the development of engineering technology, new steel pile and reinforced concrete pile are more and more widely used in engineering construction. Different pile types have different characteristics.Classification according to force condition:Friction piles - most of the load is carried by the friction of the soil around the pile, while the pile at the end of the pile can be neglectedPileEnd bearing friction pile -- the pile whose load is mainly borne by the friction force of the pile bodyEnd bearing piles - most of the load is carried by the supporting force of the pile tip, while the resistance at the side of the pile is negligibleFriction end bearing pile -- the pile whose load is mainly loaded by the end of pileClassification by construction method:Mechanical hole pileBored pileImmersed tube cast-in-place pileReinforced concrete pilePile foundation, precast pile, prestressed concrete pileSteel pileCement soil mixing pileMixing pileOther chemical material mixing pilesAccording to the overall size of the pile classificationLong pilePileShort pileMiddle long stakeVariable cross-section pileAccording to the method of pile driving, prefabricated piles can be divided into driven piles, pressed piles, vibrating sinking piles, rotary piles and so on.
Q:What are the specifications and dimensions of flanges?
Flanges are a disk shaped part, most common in pipe engineering. Flanges are used in pairs.In pipe engineering, flanges are used mainly for pipe connections. In the need to connect the pipe, all kinds of installation of a flange, low pressure pipe can use wire connection flange, more than 4 kilograms pressure use welding flange. Add a gasket between the two flanges and secure with bolts.Different pressure flanges have different thicknesses and use different bolts.Water pump and valve, and in the pipe connection, these equipment parts of the equipment also made corresponding flange shape, also known as flange connection.Usually in the two plane, in the vicinity of the use of bolt connection
Q:Servo reducer and servo motor connection, flange locking screw hole is M4.5, but servo motor installation hole is Phi 5.5, what will be the impact?
Loose is small! The key is blue docking is the fine positioning and fastening screw for different screw! Will make inaccurate positioning of operation will increase the vibration!! this is generally wide hole or wide hole! If no conditions on the small end with gasket!It doesn't matter if you're small size. Just tighten the axle when you tighten it!
Q:What flange is the change-over flange?
A device that converts a form of connection (or a specification or size) into another form of connection. If the main form of this device is a flange, it can be called a change-over flange. Accordingly, there is a changeover joint and a switch socket.Connect:First, each is fixed on a flange plate, and between the two flanges, and the flange pad, the bolts are fastened together, and the connection is completed. Some pipe fittings and equipment have their own flange, but also belong to flange connection. Flange connection is an important connection way for pipeline construction. Flange connection, easy to use, able to withstand greater pressure. Flange flanges are widely used in industrial piping. In the home, the pipe diameter is small, and it is low pressure and can not see the flange connection. In a boiler room or production site, flanges are connected to pipes and equipment.
Q:What is the equipment flange?
Take it easy, don't worry. Always hungry for knowledge, and constantly explore the unknown world. If you can have a harvest every day, as long as we persist, many years later you will be invincible. Keep on learning and your dream will come true!
