* oil quantity representation method: (note: when the oil value is the same, only one oil value is used) Example 1: LD3-2 indicates LD model and the amount of 1 and 2 oil outlet in 2allocator is 0.3ml each time. Example 2:LD5-53235 indicates 5 allocators, and 1, 2, 3 outlet flow raterespectively is 0.3ml, 0.5ml, 0.3ml, 0.5ml, and 0.4ml each time. Note: among them: 7,8,9,10 bits is the combination of 5 bits and 2,3,4, or 5 bits.The 6 bits, the combination of 3 and 3 bits.
