叉車齒輪泵漏油分析及解決方法
來源:http://www.nehqer.icu/ 日期:2019-06-21 發布人:admin
叉車齒輪泵在作業中有時會出現漏油現象。齒輪泵的漏油一般可分為可分為內漏和外漏兩種:內漏使泵的輸出流量減小,壓力升不高,而外漏除以上弊病外還污染環境,所以要減小內漏,避免外漏。減小內漏的方法是適當的調整泵的運動間隙,間隙過大,內漏增加;間隙過小,摩擦增大。濟南叉車配件小編經多年經驗分析齒輪泵造成外漏有以下幾個原因:
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、前后泵蓋上的回油孔被堵,或加工時此孔未被鉆通。處理方法:需要清洗或鉆通。
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、泵蓋與密封圈配合過松形成漏油,處理方法:可通過調整間隙來解決。
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、軸封唇口被主軸鍵槽劃傷或骨架彈簧脫落。處理方法:可以更換油封或重新安裝。
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、零件密封面劃傷嚴重。處理方法:對密封面重新研詹一消除劃痕。

4. Serious scratches on the sealing surface of parts. Processing method: Re-study the sealing surface to eliminate scratches.
五、油封溝槽內徑過小或溝槽倒角太小,使油封裝斜了,而導致漏油。處理方法:檢查溝槽尺寸,按規定加工溝槽或倒角。
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、軸倒角處太粗糙或倒角太小,使密封件唇口翻卷。處理方法:檢查粗糙度或倒角。在裝配時,應在倒角處打上油脂。
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、密封件在高溫下使用過久、或密封件膠質不好、或裝配不當失去彈性造成外漏,處理方法:需更換密封件。
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.
安裝時,泵體裝反,使出油口接通卸荷槽?;蛘咴谠囖D對,轉向搞錯,軸上的油封被擊穿而引起外漏。這是因為泵的進油口通過回油通道與油封相連。當泵反轉時,進油口變成了排油口,壓力油通過回油通道而擊穿油封,或將油封沖出泵體形成外漏。這應該,糾正泵的轉向,并更換新的油封。
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.
