Một yếu tố không thể thiếu trong tài liệu bao phủ mái nhà là các bản vẽ kỹ thuật. Những bản vẽ này cần phải được vẽ một cách chi tiết và chính xác, từ hình dáng tổng thể đến từng chi tiết nhỏ như các đường ống thoát nước, hệ thống cách nhiệt và các loại vật liệu chống thấm. Điều này không chỉ giúp cho việc thi công diễn ra suôn sẻ mà còn giảm thiểu rủi ro trong quá trình xây dựng.

High-Pressure Rotary seals that are used for high-pressure applications have a solid cross-section, are developed to seal a pressurized lubricant, and possess hydrodynamic waves that encounter the pressurized lubricant. These fluid waves pump lubricant into the engaged sealing interface when the shaft spins.
The introduction of skeleton oil seals
Generally said that the oil seal refers to the skeleton oil seal.The function of the oil seal is generally to isolate the parts that need lubrication in the transmission parts from the external environment, so as not to let the lubricating oil leak.The skeleton acts like the steel bars in a concrete member to strengthen and keep the seal in shape and tension.According to the structure, it can be divided into single lip skeleton oil seal and double lip skeleton oil seal.The auxiliary lip of the double lip skeleton oil seal plays a dust-proof role, to prevent the outside dust, impurities and so on into the machine.According to the frame type, it can be divided into inner frame oil seal, exposed frame oil seal and assembled oil seal.According to working conditions, it can be divided into inner frame oil seal, exposed frame oil seal and assembled oil seal.According to working conditions, it can be divided into rotating frame oil seal and round-trip frame oil seal.Used for gasoline engine crankshaft, diesel engine crankshaft, gearbox, differential, shock absorber, engine, axle and other parts.
The skeleton oil seal structure is composed of three parts: oil seal body, strengthening framework and self-tightening spiral spring.The sealing body is divided into the bottom, waist, cutting edge and sealing lip according to different parts.Generally, the inner diameter of the skeleton oil seal in the free state is smaller than the shaft diameter, that is, it has a certain amount of interference.
Therefore, when the oil seal is loaded on the oil seal seat and shaft, the pressure on the edge of the oil seal and the contraction force of the self-tightening spiral spring produce a certain radial tightening force on the shaft. After a period of operation, the pressure will rapidly decrease and even disappear. Therefore, the self-tightening force of the oil seal can be compensated at any time with the spring.
