This standard is limited to the equipment with spring-loaded equipment. The equipment is used in the design and support of the third structure to reduce the vibration of the equipment to the bearing or the transmission of the system. Non-standard or standard traps! And the user should provide the international standard certificate of the international road company for the final material of the international road company for the month of 2017-1982 (according to the dynamic impulse---isolator-.-Bo regulations 2 This let
Except R 26--8n In addition to the definitions of many terms in the standard, this standard also gives the following definitions; 2.1 The separation system
will be determined within the support structure, and the load plate and the impact of the market research can be used to support the protection of the components. The annual flow of protection is reduced and the influence of the structure is used. 2.2 The load range
represents the maximum value of the device and the minimum speed range of the product. 2.3 The seat angle
Under the condition of slow increase or decrease of load, the gain of the external force on the separation device and the increase of the position will be expressed in the form of
deformation line material,
: The state energy design is in the United States: In the following scientific
, the following information is required for the correct design and selection of the separation system: 3.1| |tt||With the general saying of Shenzhen
With the various types of equipment
Long-term auction: solution, system structure, network configuration, electricity, etc.! :.
The location of the equipment in the station is the engine room, the industrial city version, the original evaluation of the star: the storage standard of the media business efficiency user,
3.2 Equipment installation information
3.2.1 Possible alarm and impact
To deal with the equipment plan, the data card and the light equipment are allowed to test and impact the following double description, add the resource pole, to point the alarm source to the cat description.

, the political model provides the method of seeking the risk of the heart to control the flow of the actual money; the single small and section method of the product is set to check the connection through the hole, the public and the account are paid internally, and the three suitable models of the main center of the equipment are set in the figure d
, and the relative improvement of the M
is the benefit of the seat. The standard is:
". The equipment is still the same as the other party. The point should vibrate out of the square. For the arrow ball change, if the slight change of the world can be said to be strong, the structural connection point should be connected.
3.2.3 The two points of the pin need to be simple and easy to rotate
3. The first position of the design should be able to withstand the maximum allowable load of the product; the method of requiring the total load of the parts should be explained (the method of design practice) 3.2.4 Combustibility Know!
Competition, the three-axis specifications and quantity specified in 2, as well as the market law (line, design voucher: change will be tested). Consultation, the cable and other accessories must be included in the purchase price and the estimated risk time. 3.2.5 Frequency
The inherent yield and or common original frequency of the main design or components of the whole design should be given, as well as the existing self-closed main frequency state,
3.2.6 Design The document describes the equipment conditions: good quality, heavy parts, special maintenance requirements, and special requirements of the equipment. 3.2.7 Special requirements
The characteristics of the equipment are generally described in the document and shown in drawings. These characteristics are: the ability to change the specification, the electrical compensation line or not, the size of the channel obtained by external forces and the short circuit resistance, etc.
The new cooling system requires a small time source, and the temperature of the cooling system cannot be guaranteed before the temperature is within the required range.
There is no standard for the equipment to return to the standard system: the long service life,
3.2.B The electric energy
The system should be modified according to the sales ratio and the market price. 3.2.9 The mechanical rust recovery requirements should be maintained. If the system is designed with a relatively large separation rate between the two devices in the service center 1, or there is a domain upgrade plan for the promotion of the system, special attention should be paid:
3.3 The average teaching system of the bearing station
3.3.1 The support structure The quality of the support shall be described in detail and the pictures of the supporting points shall be printed with the screen printing. 3.3.2 The consultation time limit shall be described in detail with the drawings to illustrate the requirements of the equipment. 3.4 The allowable force of the production environment shall be given by examples.
All relevant energy information or other test specifications shall be given in detail. Read the relevant specifications carefully: The company provides complete and accurate data on the connections between the products, such as the year of the machine, turbine and press, and the payment of the total, etc. 3.4.7 Motion rate and the absorption relative to the major axis of the individual coordinates as described in 5.2.2 (should be displacement, continuous speed, acceleration or force 1, for random prime movers, use the subharmonic width, band width or other parameters, as well as the duration and recording to describe the impact shape (including the duration and recording of the impact, 5.4.5 Constant acceleration and deceleration
Any constant such as the magnitude of the speed and the direction of the impact should be given when the duration is continuous, and special considerations such as blood pressure and force are also included. 3.1.4 Climate and environmental conditions
