阀弹簧

First and second check valve spring modules are not interchangeable.

第一和第二止回阀弹簧模块不能互换。

We can't ignore that energy sources wasting and environment pollution has already become the necessitous problem in the developing of automobiles as unsuited enactment of the valve and aging of the spring.

我们不可忽视，由于蒸汽阀开启压力值设置的不恰当及蒸汽阀弹簧的老化，过多的汽油箱内汽油蒸汽的排出而造成的能源浪费和环境污染，已成为汽车工业发展中急需关注的问题。

For a long time, our company has specialized in manufacturing diesel valve spring, high-pressure pump, pneumatic hydraulic element spring, pressure regulating spring, delivery valve spring, plunger spring, clutch spring 、 suspension spring 、 die spring 、 disk spring 、 tension spring 、 wire form spring 、 torsion spring etc. for all kinds of motors, motorcycles, tractors and engineering machines.

本公司长期专业生产各类汽车、摩托车、拖拉机及工程机械等配套用内燃机气门弹簧、高压油泵和气动液压元件弹簧、调压弹簧、出油阀弹簧、柱塞弹簧、离合器弹簧、悬架弹簧/减振器弹簧、模具强力弹簧、涡卷弹簧、重型机械用弹簧、碟形弹簧以及拉簧、扭簧、卡簧等，钢丝线径为0.1-75.0mm。

Inspection, screw open the cylinder high-pressure pipeline joints, using hand pump pumping pumps, fuel injection pump at the top of the case found that there is oil outflow tubing connector, the valve of the oil seal bad (of course such as a broken valve spring is also this would be the case), such as cylinder seals appear undesirable situation, it should conduct a thorough debugging injection pump maintenance, the replacement of dual pieces.

检查时，拧开各缸高压油管接头，用输油泵之手油泵泵油，如此时发现喷油泵顶部油管接头有油流出，则说明该出油阀密封不良（当然如出油阀弹簧折断也会出现这种情况），如多缸出现密封不良现象，则应对喷油泵进行彻底调试保养，更换偶件。

To burning the heavy oil in diesel locomotive, the injection unit must be adjusted, such as the clearance of piston, the spring character of unilateralism valve, the needle valve lift of injector and so on. At the same time, the parameter of injection, such as the injection advace angle, the injection time, should be adjusted according to the actual instance.

针对燃用重柴油的实际，需对柴油机喷射元件，如：喷油泵柱塞偶件间隙、出油阀弹簧刚度、喷油器针阀升程、及喷射参数，如：喷油提前角、喷油定时等均需作出调整，本文论述了具体的调整方法和依据。

Injector fuel supply or pressure is not enough, atomization bad, drip, etc.; plunger rod adjustable arm or teeth protruding ears from the governor lever fork slot prolapse in non-oil position; fuel pump plunger and barrel assembly seriously wear and tear, oil pressure is too low, the oil valve wear serious Mifengbuyan; washer crack and deformation, a broken valve spring, injector wear and tear stuck in the closed position.

喷油器不供油或压力不足、雾化不良、滴油等；柱塞调节臂或齿杆凸耳从调速杠杆叉槽中脱出处于不供油位置；喷油泵柱塞偶件严重磨损，供油压力太低，出油阀磨损严重，密封不严；垫圈开裂变形，出油阀弹簧折断，喷油器磨损卡死在关闭位置。

It works as shown in Figure 2b, when the work when the system is high pressure, EF mouth also in high pressure, high pressure Balance Valves unloading of oil equivalent one-way valve open and the unloading valve 3 1 contact; when the pressure exceeds the safety valve unloading having a set pressure, unloading relief valve to open, the return oil through oil path b to uninstall the spool 4, left, unloading Safety valves valve spring to overcome the spring force 5, unloading spool shifted to the right, EF population of high-pressure oil through direct discharge port T Dutch tank.

其工作原理如图2b所示，当工作系统处于高压状态时，EF口也处于高压状态，高压油打开等值卸荷单向阀3与卸荷安全阀1接触；当压力超过卸荷安全阀调定压力时，卸荷安全阀开启，其回油经油道b到卸载阀芯4左端，克服卸载阀弹簧5的弹簧力，卸载阀芯右移，EF口的高压油经T口直接卸荷油箱。

Moreover, the author analyzed and researched dynamic load of the needle valve spring by adopting the method of characteristic line and proposed to design the needle valve spring using its dynamic load.

运用特征线法研究和分析针阀弹簧的动力负荷，推导出采用动载法设计针阀弹簧的方法，从而提高设计的稳健性。高压共轨喷油器精度和技术要求高，加工难度大。

Then the influence of flow, pipe length, setting pressure of relief valve and stiffness coefficient of main valve spring on the water hammer peak pressure at the instant of fuel pistol closing was studied according to the detected pressure signals. Finally, the relatively accurate gas-liquid separation value and critical cavitation pressure value of the system was obtained by frequency analysis and wavelet analysis.

根据测得的压力信号，对燃料枪关闭瞬间流量、管长、溢流阀调定压力以及主阀弹簧刚度对水击效应引起的峰值压力的影响进行研究，并通过频率分析方法和小波分析方法较精确地获得系统的气液分离值和临界汽蚀压力点。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。
