It depends on what type of bearing needs to be purchased, but most of them are similar.

For example, 100,000 sets of bearings need to be purchased.

Then it is necessary to write the content of the purchase, that is, the model, quantity, unit price, delivery date, remarks, etc., and then there should be quality clauses on the contract

1.It is required that the dimensional tolerance of the product should meet the national standard.

2.The product clearance is C3

3.Bearing material: GCR15

4.The rotation feels good.

5.What grease is required to be filled with what to say to the factory.

Then there are the packaging requirements, whether the requirements are cartridge or single carton packaging, and then the outside carton is neutral or branded, whether the carton needs to be labeled on the outside, etc.

If it is a ** company, far away from the supplier, you can let the supplier send samples to see, for hardness, generally do not test, unless the customer requirements are very strict, Size: As long as it is in line with national standards, it is OK, material: to see what material is not needed:

There are bearing steel, stainless steel, ceramics, etc., finish: that is, surface roughness, which is a national standard.

Drawings: Of course, it is provided as much as possible, and the required material, size, clearance, tolerance, and roughness will be represented on the drawings.

Of course, the quality is stable.

I am bearing production and wholesale, manufacturers love direct sales, welcome to inquire and cooperate.

This needs to be specified according to the requirements of your own equipment, if there are no special requirements, just purchase according to the national standard.

Stiffness, clearance, diameter standard.

1。The specifications and models should be clear: such as accuracy, pressure range, gauge diameter, and connection thread.

2。Agree on the delivery period.

3。Whether a certification certificate is required.

4. Packaging, transportation methods (self-pickup, delivery, etc.).

Professional manufacturers need the following parameters:

Measure the temperature, corrosivity, and state of the medium (select wetted material, heat dissipation, etc., select spring tube, diaphragm, running-in, diaphragm, etc.).

Process piping conditions: such as vibration, pulsation, water hammer effect (selection of seismic resistance, overpressure, damping, etc.) working pressure (working pressure * is the basis for the measurement range of the pressure gauge) process connection, dial, accuracy, installation method.

Yunnan Hibot Technology Technology Department.

1. The name of the instrument: it should be clear that it is a general pressure gauge, an oxygen pressure gauge, an electric contact pressure gauge, an ammonia pressure gauge, etc.;

2. Instrument model: There are different models for different manufacturers, but they should be clearly written in the contract;

3. Gauge OD size: 40, 60, 100, 150, 200, 250.

How to purchase the right valves? What technical requirements should be paid attention to when purchasing valves:

1. The specifications and categories of valves should meet the requirements of pipeline design documents.

1. The model of the valve should indicate the national standard number requirements according to it. If it is an enterprise standard, the relevant description of the model should be indicated.

2. The working pressure of the valve requires the working pressure of the pipeline, and the working pressure that the valve can withstand should be greater than the actual working pressure of the pipeline without affecting the first grade; When the valve is closed, any side should be able to withstand the working pressure value of the valve without leakage; When the valve is opened, the valve body should be able to withstand the requirement of twice the working pressure of the valve.

3. The valve manufacturing standard should indicate the national standard number based on it, and if it is an enterprise standard, the enterprise documents should be attached to the procurement contract.

Second, choose the material of the valve:

1. The valve material, because the gray cast iron pipe is gradually not recommended, the valve body material should be mainly ductile iron, and the grade and the actual physical and chemical testing data of the casting should be indicated.

2. The stem material, strive for the valve stem, and the large-diameter valve should also be a plugged valve stem.

3. The nut material is made of cast aluminum brass or cast aluminum bronze, and the hardness and strength are greater than that of the valve stem.

4. The hardness and strength of the stem bushing material should not be greater than that of the valve stem, and there should be no electrochemical corrosion with the valve stem and valve body under water immersion.

As long as you can make a table, you can take a look at the above book to understand

Seeing so much you say, I think most of them are! There are many kinds of purchasing! It's the same with machine shops!

If you want to do a good job in procurement, at least you need to know what your company needs, basic knowledge. Don't think about being a purchasing supervisor just because you don't know anything! Let's go to the workshop and learn slowly, and talk to the boss when you know what your company needs and what is most practical!
