Seal selection parameters: medium pressure, temperature, shaft diameter and speed. The selection of mechanical seal structure type is an important step in the design process, and must be investigated first: (1) working parameters - medium pressure, temperature, shaft diameter and speed. (2) medium characteristics a concentration, viscosity, corrosion, whether there are solid particles and fiber im...
Metal bellows accumulators are advanced technologies available for hydraulic systems, preferably for reducing or smoothing pressure peaks in pressure fluids. In order to ensure that the separating bellows can move freely and there is no risk of damaging its corresponding working position during operation, the outer diameter of the bellows is selected to be slightly smaller than the inner diameter ...
The outer diameter of the bellows accumulator can be advantageously selected to be smaller than the distributable inner diameter of the accumulator shell, so as to form a plurality of Subspaces in the fluid space, and the subspace as a whole forms a hydraulic buffer of the fluid. Advantageously, the sealing device can be arranged on the closed part between the guide device and the cover. In additi...
What are the main types of bellows accumulators? 1. Hammer accumulator The hammer accumulator stores and releases energy by changing the position of the heavy hammer to the north. The heavy hammer exerts a certain pressure on the hydraulic fluid through the plunger. The accumulator has the advantages of simple structure, hidden pressure, small capacity, low pressure, large size, heavy weight, larg...
The left end of the bellows accumulator is welded with the flange of the hydraulic pipeline interface, the right end of the bellows is welded with the seal ring, and the right side of the seal ring is also provided with a guide ring. Corrugated pipes are installed in the original accumulator shell, which can be deformed after being pressed, absorb the pulsating pressure in the pipeline, ensure tha...
As we all know, special valves rely on the pressure and temperature of the medium in the valve as the energy source to drive the valve to work automatically. Its sealing directly affects the performance of self operated control valves. Therefore, to improve the performance of special valves, it is necessary to continuously improve their sealing performance in use. Here are some ways to improve the...
Armored corrugated pipes refer to expandable tubular products made of plastic. Plastic corrugated pipes save materials, are light in weight, and have excellent physical and chemical properties. They are widely used in civil buildings, municipal projects, and highway bridges. The armored corrugated pipe is a corrugated pipe. The common metal corrugated pipe is carbon steel. The stainless steel or i...
The armored corrugated pipe is characterized by corresponding displacement under the action of pressure, axial force, transverse force or bending moment, pressure resistance, vacuum sealing, corrosion resistance, temperature stability and long service life. Therefore, it is widely used in many industrial fields. Various pipes are often used in daily life, among which armored corrugated pipes are w...
