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:Why Zhouzhong hole hole are matched with each other's accuracy than the low shaft
- The shaft (shaft) is a cylindrical object that is worn between the middle of the bearing or the middle of the wheel or the gear, but a few are square. The shaft supports the rotating parts and rotates with them to convey motion
- Q:What are the real half axes and imaginary half axes of the hyperbola?
- Take the hyperbola on the horizontal axis, for example, the two intersection point of it and the horizontal axis is called the apex of hyperbola
- 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:What does "axle load Limited" mean?
- Five axle vehicle gross weight of more than 50 tons, six axles and more than six axles, vehicle gross weight of goods over 55 tons and so on, the five circumstances should be deemed to be overloaded vehicles and corrected
- Q:In gear drive, what is the fit between the gear and its mating shaft?Gear and shaft coordination is clearance fit, then in the transmission process will not appear shaft and gear gap, and the loss of shaft diameter?
- There is no wear problem; the gear hole and the shaft surface have the shape error, it seems the clearance fit, but because the clearance is very small
- Q:3DMAX why can't the X axis y be solved by opening capture?
- According to the X F5 F6 in X axis Y axis lock free switch. The choice of nodes is convenient, provided that the key is checked in the 2.5 weft
- 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:How can the SketchUp move the blue axis instead of the red axis?
- Two, sometimes your object or point is locked on another plane, for exampleThe plane of motion is completely surrounded in another plane, at that time, with this planeThe non parallel movement direction will not be executed, and the CTRL can only be touched at the time of movement,Copy it to where you want it;
- Q:What are the differences between the major and minor axes of a car?
- The wheelbase is bigger, the length of the greater occupant seat space is more spacious, anti pitching and yaw performance, long wheelbase increased in straight cruising stability at the same time, to increase flexibility, decrease turning radius, the mobility of the vehicle is also worse. Therefore, there must be a trade-off between stability and flexibility to find the right balance. Of course, in the high-end long wheelbase sedan, such shortcomings have been made up of other high-tech devices.
- 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
- In the updated version of the 5.03 most powerful Chinese version of August 31st, the random custom tools have several coordinate system tools, commonly used in ant coordinates
