1, why when is two-seater a powerful person young spend the job easy oscillation?
To Chan Xin character, when medium it is to flow model when, stability of a powerful person is good; When medium it is to flow shut model when, the stability of a powerful person is poor. Two-seater a powerful person has core of two a powerful person, core laying a powerful person is in stream shut, core of a powerful person is in on flow, such, when small spend the job, stream shut model the vibration that core of a powerful person arouses a powerful person easily, this is the reason place that two-seater a powerful person cannot spend the job with Yu Xiaokai.
2, why cannot double sealed a powerful person regard as cut off a powerful person to use?
The advantage of core of a powerful person of two-seater a powerful person is equilibrium structure, allow to press difference big, and its outstanding defect is two sealing surface cannot at the same time good contact, cause leak big. If be its person the ground, mandatory the ground is used at cutting off a circumstance, obvious result is bad, even if made a lot of improvement for it (like a powerful person of double sealed sleeve) , also cannot take.
3, control valve of what vertical distance prevents a function difference, it is good that horny tenor a powerful person defends a performance?
Core of a powerful person of linear motion valve is perpendicular reduce expenditure, and medium is horizontal inpour is poured out of, the flow path inside antrum of a powerful person turns necessarily abduct, make of a powerful person shed a road to become quite complex (if appearance falls " S " model) . Such, put in a lot of dead band, the precipitation that is medium provided a space, if things go on like this, cause jam. The direction of reduce expenditure of horny tenor a powerful person is horizontal way, medium level inpour, water advection goes out, take away sordid medium easily, shed a route at the same time simple, the space that medium precipitates is very few also, it is good that so horny tenor a powerful person defends a performance.
4, why vertical distance control valve is lever of a powerful person fine?
It involves a simple mechanical principle: Sliding friction big, rolling friction is small. The lever of a powerful person of linear motion valve moves up and down, filling a bit impaction a bit, it can hire staff of a powerful person very closely, produce a bigger difference. For this, lever of a powerful person is designed very pettily, filling the 4 fluorine filling with commonly used small coefficient of friction, so that reduce a difference, but the problem that expedites from this is lever of a powerful person fine, bend easily, filling life is brief also. Solve this problem, best method uses rod of a powerful person of brigade rotary valve namely, namely horny tenor kind control valve, lever of its a powerful person is thicker than lever of linear motion valve 2 ～ 3 times, and the black lead filling that chooses life to grow, stiffness of lever of a powerful person is good, filling life is long, its attrition moment of force is small instead, answer difference small.
