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.

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 are axonometric drawings? How many are there? What are their respective features?
The item is wrong and should be isometric.Definition of isometric drawings:The body is positioned so that its three coordinate axes have the same angle (about 35 DEG 16 ') with the axonometric projection mask, and then the axonometric projection surface is projected as a positive projection. The axonometric drawings made in this way are called isometric drawings.
Q:What are the differences between axial fans and centrifugal fans?
The curved plate blade is welded to the conical steel hub. Change the flow by changing the angle of the blade in the upper inlet housing of the impeller.The casing can have an open entrance, but more commonly, it has a right angled bend to allow the motor to be placed outside the pipe. The excretory shell expands slowly to slow down the flow of air or gas and converts kinetic energy into useful static pressure.The role of axial fans and centrifugal fans in mechanical ventilation1, because the temperature and grain temperature difference is great, the first ventilation time should be chosen during the day, in order to reduce the gap between grain temperature and temperature, and reduce the occurrence of condensation. After the ventilation as far as possible in the evening, because the ventilation is to cool at night, humidity is relatively high, low temperature, so that reduce the water loss, and make full use of the night temperature, improve the cooling effect.2 centrifugal fan for ventilation early there may be a door and window and wall condensation, even slight condensation of surface grain surface, as long as the wind stop machine, open the window, open the axial fan, if necessary, changes the grain surface, the positions within the hot air outside the warehouse can be excluded. When the axial fan is used for the slow ventilation, there will be no condensation. Only the upper and middle grain temperature will rise slowly, and the grain temperature will decrease steadily as the ventilation continues.
Q:Excel 2010 in the line chart, how to add title, how to X axis and Y axis name?
Titles can be added in the layout toolbar, but coordinates are not available and can only be added to the text box.
Q:How does the Maya move the coordinate axis?
When the movement is finished, press the insert button again to get back to normal
Q:Now mechanical keyboard what black axis, red axis, green axis, tea axis, ask God detailed explanationOne by one to talk about what are the characteristics.
Black shaftIs not the sense of paragraph, click down, in the end, the pressure increases gradually from top to bottom, black is the most widely used market shaft axis, but the name of the game under the banner of the keyboard must use black shaft, black and white shaft axis of the problem is the same, the pressure is whether you can use black shaft, but I I recommend the black shaft, because black shaft has a characteristic that is not required by the end, shaft can trigger, which means that you can only do with quick way to tap the black shaft keyboard, there will be a finger to massage feeling after the superficial habits, the reasons for the game, is a straight handle for smooth operation.
Q:What are the paraxial approximation conditions in physical optics?
Paraxial optics is set all optical conditions of basic formula, SIN = theta theta meet,
Q:How to use CAD to draw axonometric drawing
In the command line, enter: DS enterPoint capture and raster capture type: equal axis capture.Back to the drawing area, press "F8" to open the orthogonal mode
Q:Who can say in detail under the axle, burning tile, cylinder, cylinder, storm what meaning.
The main solution is: to regularly check the oil and a high degree of quality, the replacement of oil, oil filter and air filter regularly. In the vehicle at the beginning (especially in winter) do not rapidly increase the engine speed, should keep the engine running idle for a few minutes, the engine at full lubrication started again.
Q:Machining process of transmission shaft
Shaft parts are one of the typical parts often encountered in machines. It is mainly used to support transmission parts, transfer torque and bear load. Shaft parts are rotating parts, the length is greater than the diameter, generally by the concentric shaft of the cylindrical surface, cone surface, inner hole and thread and the corresponding end face. According to the shape of the structure, the shaft parts can be divided into optical axis, ladder shaft, hollow shaft and crankshaft.
Q:Who can explain the normal stress and the axial force?. Shear stress and shear force
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.
