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: What is the slip shaft of the slitter?
- Slip shaft is used for cutting and rewinding tension product, slip shaft above the slip rings according to each volume of material tension size, coiling, each volume of the material above the slip ring with axial slippage, the tension balanced and stable effect, and finally the product end winding it's neat, tight moderate, well solves the disadvantages of inflatable shaft (the end winding material not neat, some very loose, some tight deformation)
- Q: That's the line of the painting. It's just moving the coordinate axis. I want to make a rotation of the custom axis. Which prawns help me?!
- Well, the insert key on the keyboard moves the coordinate axis of the selected object
- Q: What are the differences between axial fans and centrifugal fans?
- The main difference between centrifugal fans and axial fans is that:1. The centrifugal fan changes the flow direction of the medium in the air duct, while the axial fan does not change the flow direction of the medium in the air duct;2, the former installation is more complex3, the former motor and fan are generally connected through the shaft, the latter motor generally in the fan;
- Q: What's the camshaft phase shifter for?
- Function and typeCrankshaft position sensor (Crankshaft Position, Sensor, CPS) also known as the engine speed and the crank angle sensor, its function is to collect the crankshaft rotation angle and the engine speed signal, and input the electronic control unit (ECu), in order to determine the ignition timing and injection timing.
- 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?
- In exceptional cases, the upper and lower deviations of the shaft, such as the shaft, are not allowed to change
- Q: What does the structural design of the shaft include?
- The design of the shaft structure is mainly to determine the shape and size of shaft. In general structure design condition: assembly drawing machine, shaft speed, transmission power, shaft parts of the main parameters and dimensions.
- Q: In EXCEL, to compare with the month of sales, product gross margin%, because these two numbers are too big to show in the main shaft
- Right column graphs and line charts select "add data labels" and adjust the value of the position to show the complete diagram.
- Q: What are the differences between the temperature instrument, axial type and universal type, radial type?
- Its products are flexible in appearance and beautiful in appearance, and have reached the standard of similar products in Europe and america. Our factory has been unanimously recognized as the most comprehensive manufacturer in China. Our most powerful advantage lies in the complete range of products, the most abundant stocks and the best quality and inexpensive
- Q: How do you change animations in PS to frames instead of time axes?
- The animation panel has an icon with a frame at the lower corner. Click it! Hope to be of help to you!
- Q: What do you mean by six axis and four linkage?
- Is the tool x, y, Z can move, and then there is a tool, the direction can rotate is the 4 axis, and then there are two directions to rotate, that is, the 5 axis. And then there are two directions to rotate, that is, the 5 axis. The three directions can be rotated, that is, the 6 axisFour moving lower programming requirements, in the processing of certain parts of the workpiece, which use only 4 degrees of freedom, the other two fixed, can simplify the programming requirements. Such as fixed distance and the axial rotary tool spindle machining, a knife, and then use a fixed two parameters processing under the knife in order to complete a process, such as the workpiece surface.
