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.

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: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
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 gear drive, what is the fit between the gear and its mating shaft?
Assembly is not easy (especially when the axial size is large). There are also gear and shaft mating using H7/k6, which is used in high-power, high torque transmission, is to prevent vibration caused by large and loose
Q:What is radial and axial?I want to measure the radial and axial runout of the piston rod. What is radial and axial?
What you call "beat" is the deviation between the actual size and the basic sizeFor example, the outside diameter of your axis, you want 50mm, and then you actually measure 50.01 or 50.6, etc. other values, this value is more than or less than your basic size, that is, the value of the beating
Q:3DMAX why can't the X axis y be solved by opening capture?
Changed to two dimensional modeBut normal 2.5 dimension is OKYou put the mouse into a single shaft on the line
Q:What is the driving shaft in the conveyor and what is the passive shaft?
The active shaft and the passive shaft should be a pair of directly adjacent shafts connected by transmission (gears, pulleys, sprockets). Which axis is near to the power source, which is called the driving shaft, but the one near the working axis...............
Q:When you mark the axis number, it indicates that the selected axis is not the starting axis. It can not be continuously marked with the axis number
Solution: the change command, select all axis, P directive, e directive, elevation 0 input or not, if the landlord can hold shift, then press and hold the wheel rotation section, a meter to see in 3D state. The axis across the sky, selected after the Z coordinates to the initiation and termination are changed to 0, then back to the top as the basic icon note will not be a problem.
Q:What are the differences between axial and oblique strikes of hydraulic generators?
Oblique impact:For medium and high head water sources, from 10 meters to 100 meters head water can be, the relative water demand is not so great. Water head drop is about 10 meters, 75mm pipe water diversion, you can use 300W, 600W and other power machine
Q:Machining process of transmission shaft
(1) dimensional accuracyIn order to determine the position of the shaft, the axle journal usually requires higher dimensional accuracy (IT5~IT7). The shaft neck dimensions of the assembly drive are generally low in accuracy (IT6~IT9).(two) geometry accuracyThe geometry precision of shaft parts is mainly refers to the journal, the outer cone, the cone Morse roundness, cylindricity, general tolerances should be restricted in size within the tolerance range. For the inside and outside surface with higher precision, the deviation of the drawing should be marked on the drawing.
