The key techniques of vacuum pump in beef preservation mainly include the following points: 1.Vacuum packaging: Vacuum packaging achieved by a vacuum pump is an effective means to extend the shelf life of beef. Vacuum packaging can reduce the contact between beef and oxygen, inhibit the growth of microorganisms, and thus extend the shelf life. 2.Temperature control: Temperature control is crucial ...

The basic structural formation of the air compressor cylinder is the key to ensure its effective operation. According to professional literature and information, the cylinder assembly mainly includes the following parts: 1.Cylinder block: As the frame of the air compressor, it supports the moving parts of the crank-connecting rod mechanism, forms cooling water channels, oil channels, and air chann...

The air compressor cylinder liner is an important component in the air compressor, which has the following main functions: 1.Guiding function: The cylinder liner provides a stable motion track for the piston, ensuring that the piston reciprocates in a straight line in the cylinder, reducing friction and wear. 2.Forming working space: The cylinder liner and piston together form the working space fo...

The rotor structure of the vane compressor is the core part of the equipment. Its design and function have a direct impact on the performance of the entire compressor. The following is an introduction to the rotor structure of the vane compressor: 1.Rotor configuration: The rotor of the vane compressor is eccentrically installed in the cylinder. This eccentric configuration allows the vanes instal...

The unloading and anti-friction structure design of the vane compressor is to reduce the mechanical friction between the vane and the cylinder, and improve the operating efficiency and service life of the equipment. The following are some key unloading and anti-friction structures: 1.Unloading ring: Unloading rings that can rotate freely are arranged at both ends of the cylinder. The inner diamete...

The oil return pipe of the screw air compressor is an important part of the oil circulation system. Its main functions include: 1.Stable oil return: The oil return pipe smoothly draws the lubricating oil at the bottom of the oil-gas separator back into the compressor casing to maintain the stability of the oil circuit circulation. 2.Prevent oil loss: The oil return pipe is equipped with a filter, ...

The minimum pressure valve (also called pressure maintaining valve) of the screw air compressor is a key component in the oil circulation system and is located at the outlet above the oil-gas separator. Its main functions include: 1.Ensure that the circulating pressure required for lubrication can be quickly established when the air compressor is started to prevent equipment wear caused by poor lu...

In the oil circulation system of the screw air compressor, the temperature control valve is an important component. Its main function is to control the cooling process of the lubricating oil to maintain the optimal working temperature. The following is an introduction to the temperature control valve in the oil circulation of the screw air compressor: 1.Function of temperature control valve: The t...
