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
- Since the spindle of the lathe contains steps and inner holes, it can fully reflect the characteristics of the shaft parts, so the main shaft is used as an example1, the first two forging blank center hole, coarse outside the circle several stalls 2 steps; quenching; 3, semi refined car stall level, and then take the length of discharge allowance, Center for a total length of 4 cars; the central frame shaft through hole drilling; 5, lined both ends of the taper hole, both ends with bulkhead, central hole drilling, prepare for grinding; 6, finishing the file outer circle and step plane, put the grinding allowance, and the groove on the outer circle, car 7, each gear grinding chamfering; cylindrical and plane to the step size; 8, after the assembly processing the thread in the lathe.
- 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?!
- When the movement is finished, press the insert button again to get back to normal
- 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: In mechanical design, how are base hole system and base shaft system chosen?
- Generally speaking, we should take the basic system as the first priority, but not the special case, so as to use the basic hole system. This is because it is more difficult to process the same size than the shaft.For example, the bearings of the bore and shaft coordination, as a result of general circumstances, you can not change the bearing bore to achieve coordination, so only the choice of base hole system. (with the bore as the base, change the size of the shaft to achieve alignment)
- 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
- 5., the secondary axis appears on the right. Because the chart is not pretty, right-click the red chart and select 'change series chart type'.
- 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?
- H7/h6 or H8/h7 coordination, depending on the specific circumstances"Then, will there be a gap between the shaft and the gear during transmission, and the axle diameter will be lost because there is no relative rotation between the gear and the shaft."
- 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: 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: When the textbook calculates the diameter of the shaft, he tells me some of his forces, such as the circumference force of the gear on the shaft, etc.. But in reality, the known conditions are quite small: "now I have a question, how to transform, please help me?"Just know that A is a cylindrical, M, radius R, B as a shaft, and A together, C motor, and B through the chain connection, will now enable A to R RPM speed rotation, so how to determine the motor power, what is the minimum diameter of the B axis? What is the moment and torque that the B axis receives if it is specific? Other conditions to be determined, free to add
- When determining the length of each shaft, it is necessary to make the structure compact and ensure the assembly or adjustment of the parts. The length of each section of the shaft is determined by the axial dimension of the mating parts of each part and the necessary clearance between the adjacent parts. In order to ensure the axial positioning reliable, and gear and couplings and other parts to match, part of the shaft length should generally be shorter than the length of the wheel hub 2 ~ 3mm
- Q: CAD axonometric drawing oblique annotation, why left and right tilt?
- Move the coordinates to the physical surface to be marked so that the annotations and coordinates are in the same coordinate system. This phenomenon will not occur when tagging again
