Tailor-made for customers all kinds of pumps with my company, kettle, bearing no pressure sintering silicon carbide mechanical seal, and all kinds of resistance corrosion pump parts and the accessories. Our company pressureless sintered silicon carbide products a reaction bonded silicon carbide products, can easily adapt to the harsh working conditions, in strong corrosive, strong wear, high temperature, high pressure, high strength harsh harsh under complex conditions is more outstanding. At the same time, our company to provide customers with nozzles, armored body armor plate and other special-shaped pieces of custom-made service.

Compared with the reaction sintered silicon carbide product (SSIC), the production process of the sintered silicon carbide product (RBSIC) is complex and the production investment is high. In addition, whether it is in the resistance to corrosion and abrasion, compressive and flexural fracture resistance of or high pressure, high temperature and other properties are more excellent, this is pressureless sintering silicon carbide products will in the near future completely replace reaction bonded silicon carbide products is one of the important reasons. The main varieties of the pressureless sintering silicon carbide products with all kinds of mechanical seal with sealing ring and moving ring and static ring, corrosion resistant pump, magnetic pump, shield pump components. At the same time, the production special-shaped pieces of nozzle, wire drawing die, armor plate. According to the drawings, we will provide customers with satisfactory products and customer satisfaction. Let customer satisfaction is one of the purposes of our company has been pursued, but also one of the objectives pursued by all the staff of our company.

Assessment Method: the specimen prior polishing, immersed in the test liquid (70OC) for 100 hours, the weight was measured and observed microstructure, weight reduction is calculated by the degree of corrosion was observed microstructure for corrosion to comprehensive judgments.
A level (corrosion): corrosion rate ≤0.125mm / ingredients in a small amount of corrosion observed slice
Level B (somewhat resistant): corrosion rate = 0.125-1.0mm / or annual corrosion rate ≤0.125mm / observe a large number of corrosion

Class C (resistant to corrosion): corrosion rate ≥1.0mm / or the main ingredient of Corrosion

Q: What is the difference between elevation and vertical elevation?See a vertical elevation in a drawing. Is it an elevation? Are there any differences between elevation, elevation and elevation?: You should say that the elevation of the shaft should be an elevation along the axis of the building, but it is rare to call it

Q: The proe rotation feature is that you can't find the rotating shaft. What's the reason why I can't pick it when I build the new axis?: And the feature of the reference axis can only be selected before the rotation feature (if the window is not selected, it can be selected from the model tree)If it's the center line inside the sketch, I don't know which version you're using. I'm using the PROE5.0,5.0 rotation feature, where there's a single center line for rotation when you're sketching

Q: What is the heat treatment method for making the shaft made of 45 steel? What is the microstructure after heat treatment?: The microstructure before heat treatment is a mixture of ferrite and cementite. Because it belongs to quenched and tempered steel, the conventional heat treatment is quenched and then tempered at high temperature. The microstructure after heat treatment is tempered bainite.

Q: What are the differences between axial and oblique strikes of hydraulic generators?: Axial flow:For low head water, the height of water head is below 10 meters. The amount of water needed is relatively large, equivalent to the amount of water above the 160mm pipe. The axial flow type of the old section needs to be constructed with cement or other materials before the installation of the water diversion channel and the vacuum vortex chamber. The indirect cost is relatively high and the project is relatively large. The new "axial flow type vortex axial flow type, this machine is not also built aqueducts and vacuum vortex chamber, directly connected pipes can use. Head height of about 2 meters, with 160mm water pipes filled with water, you can use the 300W machine. With 200mm tubes, you can use 1KW's machine. Of course, there are many matches.

Q: What is the three axis redundant flight control system?: The "telex operating system" is the Chinese free translation of the English "Fly by wire control system" (FBW), also known as the flight line manipulation system". It is an advanced electronic flight control system. A typical telex control system is composed of sensors (gyroscopes, accelerometers and other various inertial measurement devices and sensor measurement device of atmospheric angle), input device, flight control computer, steering gear and electric transmission line. The fly by wire system was originally developed to solve the stability of aircraft.

Q: What does axle control and frame control of locomotive mean?: Axis control means that each inverter independently controls a motor, and the full axis in a strict sense should include a rectifier and the intermediate loop is completely independent. But in practice, in order to reduce costs and reduce volume

Q: The difference between the drive shaft and the drive shaft and the driven shaft: The transmission shaft is the carrier used to transmit energy, and the drive shaft is used to drive other carriers

Q: In the building, the shaft net is drawn up and down, left and right,What is the meaning of "drawing in, left and right" in the drawing of the axle net in the day building? I feel that it is enough to use only the lower opening and the left entry. And there are two axis markers. Should the default be marked with 2 layers?: I. axle network1, open: table above the size of the blueprint;2, next open: table below the size of the blueprint;3 Zuo Jin: the size of the sheet on the left of the drawing;4, right into: table in the right dimensions of the drawing;

Q: Who can explain the normal stress and the axial force?. Shear stress and shear force. Does it matter? And then there is... Is shear generated in order to propagate bending moments?: If the end of shaft or any point is perpendicular to the axis of the force (such as cantilever, one end fixed and the other end or middle weight suspended), is subjected to shear stress and bending stress, shear stress is a section of shear force per unit area.2. yes. The beam (generalized) that bears the moment must be accompanied by shear forces.

Q: What do you mean by six axis and four linkage?: Six four axis is six axes, four degrees of freedom processing method. The three axis is x, y, Z, the remaining axis refers to the X, y, Z axis rotating reference, how much to achieve function is a few axes. The simple argument is that, each corresponding to a shaft a servo motor, multi axis linkage is the motor can work at the same time, the multidimensional space cooperation processing complex.
