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

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.

Features: high temperature resistance, wear resistance, corrosion resistance, oxidation resistance, hardness, heat conduction

Main products: mechanical seals, pump parts, nozzles, bullet proof plate

Mechanical seals: high hardness, high wear resistance, good self - Lubrication and high heat conductivity, so the service life of mechanical seal is greatly improved.

Pump: resistance to corrosion and wear characteristic of the pressureless sintering silicon carbide become magnetic pump sliding bearing, resistant corrosion pump sleeve, shielding pump assembly, etc. various kinds of pump of choice

Nozzle: wear resistant, high temperature resistance, high hardness characteristics of the normal pressure sintering silicon carbide nozzle to become a perfect alternative to carbide nozzle

Armor: light weight, high hardness, good ballistic performance, pressureless sintering of SiC for your life and property security escort

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: 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: There are several possible causes of this:1, the axis is not automatically generated line segments, but hand-painted multi paragraph line, format brush can change other attributes, but can not change the multi line into the axis, the default line format, so the day can not read.

Q: What is the heat treatment method for making the shaft made of 45 steel? What is the microstructure after heat treatment?: The microstructure before heat treatment is a mixture of ferrite and cementite. Because it belongs to quenched and tempered steel, the conventional heat treatment is quenched and then tempered at high temperature. The microstructure after heat treatment is tempered bainite.

Q: What are the differences between axial fans and centrifugal fans?: 4, the former is often installed in the air conditioning unit inlet and outlet, boiler drum, fan, and so on. The latter is usually installed in the middle of the air duct or the front end of the air duct.In addition, there is a diagonal (mixed flow) fan, the wind pressure coefficient is higher than the axial fan, and the flow coefficient is larger than the centrifugal fan.Fill the gaps between the axial flow fan and centrifugal fan. Meanwhile, the utility model has the characteristics of simple and convenient installation.The mixed flow (or axial thrust) fan combines the characteristics of axial and centrifugal fans, although it looks more like a conventional axial fan.

Q: A hole has a cover, a platform has a column, a wheel has a hood, a shaft must have the meaning of these four words: Railings must be made along the sides of the platform,A rotating wheel with a rotating flywheel must be provided with a safety shield,

Q: What does "axle load Limited" mean?: The traffic control department of the public security is not found above five kinds of circumstances but the cargo weight more than driving license for more than 30% of the nuclear payload, to withhold a driver's license. The day has been punished or uninstall and produce relevant documents and records after unloading weight consistent with the vehicle, shall not be punished or uninstalled.

Q: What are the failure forms of shaft parts?: Large deflection (for the simple beam of the axis, if the load is too large, will be deflection of the shaft, of course, the lack of early design reasons)5, broken (this is the most serious accident, the reasons: lack of design, material problems, heat treatment problems, processing stress, impact load is too large, and other accidents led to...... It can cause human life in serious cases!

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: Excel 2010 in the line chart, how to add title, how to X axis and Y axis name?: In the design module, there is a header in the chart layout module

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;
