The difference between the bearing  w ww.timkenbearings-hk.com/ Series Of SKF Bearings    temperature, pressure and hydraulic pressure:

The difference between the bearing temperature, pressure and Suppli10
A: the bearing temperature pressure:


Temperature pressure is known as "start a new application of a new era of powder metallurgy parts manufacturing technology", the key is that at a relatively low cost to create high performance of iron base P/M parts, spare parts for cars between performance and cost has found a better point. According to the data analysis, although the compaction process than conventional a pressure sintering process of relative components increased by 20%, but better than leach process, copper after pressure after burning technology, powder hot forging process respectively by 20%, 30% and 80%. In addition, the compaction technology also has its own unique technical advantages:


1. The lost foam casting production needed raw materials is roughly divided into the model of raw material, dry sand raw materials, coating materials, alloy smelting such aspects as raw materials. Because of the lost foam casting process is a systematic project, the selection of raw materials is particularly important. So control the quality of the raw materials and parameters is the basis of success or failure of epc.


2. The carrier of epc coating use water-based, more for the environment protection. The dope mainly including clay, sodium silicate, syrup, pulp waste liquid, white latex, silica sol, etc. In choosing adhesive to consider the following factors: high temperature hair gas; Smearing; The coating strength and stiffness; Erosion model, etc. Suspending agent used to prevent the coating deposition, layered, agglomerate, make coating has thixotropy.


2: hydraulic bearing:


Hydraulic pressure is critical in manufacturing, coordination and operation for the hydraulic performance of the parts is very important! Packing element damage is the main factors of the impurity in the working fluid. These impurities grinding between the sealing element, make the leak valve. Abroad, therefore, has put forward the corresponding grades of hydraulic components, should adopt the corresponding precision filter. They think 5 microns pump seal element, if the filter filtration precision is 3 M/mu, longevity 10 times higher than the 10 microns.


Reasonable working speed of the gear pump, gear and bearing the rotation of the mesh to avoid resonance frequency, to prevent noise. Because when close to the gear mesh frequency is likely to occur when the natural frequency of resonance. The proper vibration isolation technology can prevent vibration transfer to the adjacent structure. Therefore, the gear pump and drive motor should be through the flexible shaft coupling, and installed on the same floor, in order to assure alignment, the base plate on the elastic support, can further improve the effect of vibration isolation. On the outlet pipe of the gear pump, set up a swell to describe cavity or accumulator, to absorb the pressure pulsation of the pump or buffer the pressure of the mutations in the pipeline, is the effective measure to control the high viscosity gear pump noise.


In the processing of electrical system, with "less" for the principle, basically retained the original machine electrical system, only some of the redesign will be related to the system.


With the development of hydraulic support technology. The use of valve performance and valve life put forward higher requirements. But in fact indoor type testing and downhole working results vary widely. Now many countries in the form of the experiment, increased the anti pollution for, have a plenty of mixed with appropriate coal powder in the emulsion, have a plenty of joining mechanical impurities.
