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.

- 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: What is the axle hole?What are the shafts, bores, and key slots?
- The axle (mechanical component) edits the locking shaft (shaft), a cylindrical object that is worn between the middle of the bearing or between the wheels or the gear, but a few are square.
- Q: The transmission change ratio is defined as the input shaft speed / output shaft speed. So, is the 1 gear drive larger than the 5 gear transmission ratio?
- Split view should be control relationship between the gearbox and the speed of the engine, the clutch control left after incision impact of transmission speed has been in decline, because of the transmission loss from the driving force of the engine after the body inertia driving tire with gear rotation. The right pedal is actually controlling the speed of the engine.
- Q: What is the heat treatment method for making the shaft made of 45 steel? What is the microstructure after heat treatment?
- The method of heat treatment after quenching and tempering at high temperature is called quenching and tempering. High temperature tempering means tempering between 500-650 degrees centigrade. Quenching and tempering can make the properties and material of steel be adjusted greatly. The strength, plasticity and toughness of the steel are better, and it has good comprehensive mechanical properties. The tempered bainite is obtained after quenching and tempering.
- Q: With regard to the matching system, when to choose the base hole system, when to choose the basic shaft system, what are the basis for selection?
- At this time, the base shaft system (for example, the outer diameter of the rolling bearings is matched with the holes is the shaft system fit).
- Q: How do I display the arrow of the Y axis and the X axis in the Geometer's Sketchpad (I didn't draw the arrow, ah, the following picture)picture
- The default coordinate system of geometric sketchpad axis is not the arrow, which is consistent with the mathematical requirements, but not in line with people's habits, the coordinate system has an end, is represented by a straight line segment, especially to print papers. These exercises require the coordinate system in the limited range, which coordinates with an arrow and the image size is limited.
- Q: How to use CAD to draw axonometric drawing
- Enter in the command line: L (line command, start drawing)You'll see that the direction is limited. You can press "F5" to switch between three faces, and try it
- Q: What's the axis control of the mouse?
- The mouse moves ten times distance in the vertical direction to reach the same distance in the horizontal direction on the screen.
- Q: How do you change the pixel Z axis coordinates of CAD to 0 at a time?
- Method oneZ axis clearing operation in CAD, select all the lines in CAD, and then enter the ch space, there will be a Z feature, the coordinate axis in the properties bar inside, he replaced 0. Note: only the line will display the coordinate data. So the first clean up your CAD
- 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
