叉车齿轮泵漏油分析及解决方法
来源:https://www.jnhhcc.com/ 日期:2019-06-21 发布人:admin
叉车齿轮泵在作业中有时会出现漏油现象。齿轮泵的漏油一般可分为可分为内漏和外漏两种:内漏使泵的输出流量减小,压力升不高,而外漏除以上弊病外还污染环境,所以要减小内漏,避免外漏。减小内漏的方法是适当的调整泵的运动间隙,间隙过大,内漏增加;间隙过小,摩擦增大。济南叉车配件小编经多年经验分析齿轮泵造成外漏有以下几个原因:
Oil leakage sometimes occurs in the operation of forklift gear pump. The oil leakage of gear pump can be divided into internal leakage and external leakage. The internal leakage reduces the output flow of pump and the pressure rise is not high. Besides the above disadvantages, the external leakage also pollutes the environment, so it is necessary to reduce the internal leakage and avoid the external leakage. The method to reduce the internal leakage is to adjust the movement clearance of the pump appropriately. If the clearance is too large, the internal leakage will increase; if the clearance is too small, the friction will increase. Jinan forklift truck fittings small knitting after years of experience analysis gear pump leakage caused by the following reasons:
一、前后泵盖上的回油孔被堵,或加工时此孔未被钻通。处理方法:需要清洗或钻通。
1. The oil return hole on the front and rear pump caps is blocked or not drilled during processing. Processing method: Need cleaning or drilling.
二、泵盖与密封圈配合过松形成漏油,处理方法:可通过调整间隙来解决。
Second, the pump cover and seal ring cooperate too loosely to form oil leakage. The treatment method can be solved by adjusting the clearance.
三、轴封唇口被主轴键槽划伤或骨架弹簧脱落。处理方法:可以更换油封或重新安装。
3. The lip of the shaft seal is scratched by the key groove of the spindle or the skeleton spring falls off. Processing method: Oil seal can be replaced or reinstalled.
四、零件密封面划伤严重。处理方法:对密封面重新研詹一消除划痕。

4. Serious scratches on the sealing surface of parts. Processing method: Re-study the sealing surface to eliminate scratches.
五、油封沟槽内径过小或沟槽倒角太小,使油封装斜了,而导致漏油。处理方法:检查沟槽尺寸,按规定加工沟槽或倒角。
Fifth, too small inner diameter of oil seal groove or too small chamfer of groove make the oil seal inclined and cause oil leakage. Processing method: Check the groove size and process grooves or chamfers according to regulations.
六、轴倒角处太粗糙或倒角太小,使密封件唇口翻卷。处理方法:检查粗糙度或倒角。在装配时,应在倒角处打上油脂。
6. Shaft chamfer is too rough or chamfer is too small, so that the seal lip is rolled up. Processing method: Check roughness or chamfer. When assembling, grease should be applied at the chamfer.
七、密封件在高温下使用过久、或密封件胶质不好、或装配不当失去弹性造成外漏,处理方法:需更换密封件。
7. Seals are used too long at high temperature, or the seals are not well gelatinized, or improperly assembled to lose elasticity, resulting in leakage. Treatment methods: Seals need to be replaced.
安装时,泵体装反,使出油口接通卸荷槽。或者在试转对,转向搞错,轴上的油封被击穿而引起外漏。这是因为泵的进油口通过回油通道与油封相连。当泵反转时,进油口变成了排油口,压力油通过回油通道而击穿油封,或将油封冲出泵体形成外漏。这应该,纠正泵的转向,并更换新的油封。
When installed, the pump body is reversed to connect the outlet to the unloading groove. Or the oil seal on the axle is broken down and leaks out because of the wrong turning and trial turning. This is because the oil inlet of the pump is connected with the oil seal through the oil return channel. When the pump reverses, the oil inlet becomes the oil outlet, and the pressure oil breaks through the oil seal through the oil return channel, or washes the oil seal out of the pump body to form leakage. This should correct the steering of the pump and replace the new oil seal.
