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.

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

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 do you mean by eccentric and eccentric axes?
Oral expression "ha ~ bias" is the distance between the point of action of the object or force, the distance from the center, the eccentricity along the axis and the eccentricity of the axis, respectively, the distance from the X to the Y.
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?
Since the hole is difficult to process, the shaft is easy to process, so choose the base hole system when choosing the matching system
Q:What is the heat treatment method for making the shaft made of 45 steel?
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 is the difference between elevation and vertical elevation?
You should say that the elevation of the shaft should be an elevation along the axis of the building, but it is rare to call it
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:How to use CAD to draw axonometric drawing
Enter in the command line: L (line command, start drawing)You'll see that the direction is limited. You can press "F5" to switch between three faces, and try it
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
For the specific use: click the "custom tools" - "ants coordinate" - "the plane rectangular coordinate system (parameter free version)", in the drawing point blank two (only two), then click the "mobile arrow tool" release tool, click the menu "initialization" coordinates, you can use coordinate system.Limited on function image, not in your question.
Q:What is the driving shaft in the conveyor and what is the passive shaft?
Driven by power equipment is the driving shaft, the other shaft is the passive shaft.
Q:What is the difference between the single shaft and the double shaft of the motor?
The double output shaft means that both ends of the motor are output shafts, and there are not two output shafts.This structure is used on certain occasions, such as some old-fashioned cranes.
Q:What are the differences between axial and oblique strikes of hydraulic generators?
Axial flow:For low head water, the height of water head is below 10 meters. The amount of water needed is relatively large, equivalent to the amount of water above the 160mm pipe. The axial flow type of the old section needs to be constructed with cement or other materials before the installation of the water diversion channel and the vacuum vortex chamber. The indirect cost is relatively high and the project is relatively large. The new "axial flow type vortex axial flow type, this machine is not also built aqueducts and vacuum vortex chamber, directly connected pipes can use. Head height of about 2 meters, with 160mm water pipes filled with water, you can use the 300W machine. With 200mm tubes, you can use 1KW's machine. Of course, there are many matches.
