  • Patent number: 11421687
    Abstract: A water lubrication screw type air compressor includes a compressor, an air-loop system and a water-loop system. The water-loop system includes a water supply device, a first water-loop unit and a second water-loop unit. The water supply device includes a first water-treatment device to modify the water quality and provide purified water. The first water-loop unit includes a second water-treatment device to modify water quality and reduce the corrosion of metal components. The second water-loop unit includes a water filter to remove the impurities in water and maintain the purity of cycling water. Therefore, the water-loop system in the present disclosure includes multiple water-treatment devices and filters to maintain the water quality. The purified water ensures better cooling, lubrication and air proofing when injected into the compressor.

  • Patent number: 10718332
    Abstract: A water lubrication air compression system disposes an lubricant heat dissipation system at a bearing chamber close to the high pressure end of the compressor for cooling and circulating lubricant due to the rise of temperature during operation of the compressor, hence enhancing the ability and stability of the compressor. On the other hand, a negative pressure system is connected to the air chambers between the oil lubrication and the water lubrication of the compressor in order to provide a negative pressure. If any leak of water vapor at the compressor chamber or oil vapor at the bearing chamber, the negative pressure system is able to produce a negative pressured condition toward the sealing structure so that the oil lubrication can be effectively isolated from the water lubrication and inter-contamination between the lubricant and water can be avoided.

  • Patent number: 5818877
    Abstract: A method generates a reduced number of values representing a sequence of grouped data values and partitions the reduced number of values by first mapping data values into groups of symbols and then partitioning the resulting stream of symbols. The digits representing the first data value in each group are replaced with symbols from a first alphabet. The most significant digit of the second data value in each group and the sign of that second data value are also represented by a symbol from the first symbol set, while the remaining significant bits of the second data value in each group are represented by symbols from a second symbol set. A stream of symbols which represent a sequence of grouped data values is partitioned into first partition symbol groups and second partition symbol groups. Each first partition symbol group comprises the symbols representing the first data value in each group and also the symbol representing the least significant bit of the second data value which follows.
