（2） 顎式破碎機所采用潤滑脂應(yīng)根據(jù)使用的地點、氣溫條件下而定，一般情況下采用鈣基、鈉基和鈣鈉基潤滑脂。

（3） 加入軸承座內(nèi)的潤滑脂為其空間容積的50%左右、每3~6個月 換一次。換油時應(yīng)用潔凈的油或油清洗滾柱軸承的滾道。

（4） 顎式破碎機開動前，推力板與推力板支座之間應(yīng)注入適量的潤滑脂。

2. 顎式破碎機維修　　

為保證顎式破碎機的正常工作，除正確操作外，必須進行計劃性維修，其中包括日常維護檢查，小修、中修和大修。

（1） 小修主要內(nèi)容包括檢查并修復(fù)調(diào)整裝置，調(diào)整排料口間隙，對磨損的襯板調(diào)頭或 換。檢查傳動部分、潤滑系統(tǒng)及時跟換潤滑油等。小修的周期為1~3個月左右。

（2） 中修處進行小修的工作外，還包括 換推力板、襯板、檢查并修復(fù)軸瓦等。中修的周期一般為1~2年左右。

（3） 大修 處進行中修的工作外，還包括和 換車削偏心軸和鄂心軸，澆鑄連桿頭上部的巴氏合金， 換或修復(fù)個磨損件。大修的周期一般為5年左右。

注意事項

（1） 破碎機正常運轉(zhuǎn)后，方可投料生產(chǎn)。

（2） 待碎物料應(yīng)均勻地加入破碎機腔內(nèi)，應(yīng)避免側(cè)向加料或堆滿加料，以免掉邊過載或承受過載。

（3） 正常工作時，軸承的溫升不應(yīng)該  過30℃，很高溫度不得  過70℃。  過上述溫度時，應(yīng)立即停車，查明原因并加以排除。

（4） 停車前，應(yīng)先先停止加料，待破碎腔內(nèi)物料  排出后，方可關(guān)閉電源。

（5） 破碎時，如因破碎腔內(nèi)物料阻塞而造成停車，應(yīng)立即關(guān)閉電源停止運行，將破碎腔內(nèi)物料清理干凈后，方可再行起動。

（6） 顎板一端磨損后，可調(diào)頭使用。

（7） 破碎機使用一段時間后，應(yīng)將緊定襯套松動而損傷機器。

maintenance methodas

1. Lubrication of jaw cruasher

(1) Regularly paying attention to and timely lubricating the friction surface can ensure the normal operation of the machine and extend its service life.

(2) The lubricating grease used for jaw cruashers should be determined according to the location of use and temperature conditions. Generally, calcium based, sodium based, and calcium sodium based lubricating greases are used.

(3) The lubricating grease added to the bearing seat is about 50% of its spatial volume and should be replaced every 3-6 months. Clean the raceway of the roller bearing with clean gasoline or kerosene when changing the oil.

(4) Before starting the jaw cruasher, an appropriate amount of lubricating grease should be injected between the thrust a plate and the thrust a plate support.

2. Maintenance of jaw cruasher

To ensure the normal operation of the jaw cruasher, in addition to correct operation, planned maintenance must be carried out, including daily maintenance checks, minor repairs, medium repairs, and major repairs.

(1) The main content of minor repairs includes checking and repairing adjustment devices, adjusting the clearance between discharge ports, and turning or replacing worn lining a plates. Check the transmission part, lubrication system, and replace lubricating oil in a timely manner. The cycle of minor repairs is about 1-3 months.

(2) In addition to carrying out minor repairs in the maintenance department, it also includes replacing thrust a plates, lining a plates, inspecting and repairing bearing shells, etc. The maintenance cycle is generally around 1-2 years.

(3) In addition to carrying out intermediate repairs at the major repair department, it also includes replacing and turning eccenltric shafts and jaw shafts, ceasting Bababitt alloy on the upper part of the connecting rod head, and replacing or repairing worn parts. The overhaul cycle is generally around 5 years.

The causes and troubleshooting methodas of jaw cruasher faults

Troubleshooting methodas for the causes of faults

1. The flywheel rotates but the moving jaw stops swinging. 1. The thrust a plate is broken

2. Damaged connecting rod

3. Spring fracture 1. Replace the thrust a plate

2. Repair the connecting rod

3. Replace the spring

2. Loose teeth a plate, metal impact on teeth a plate fixing screws or side wedges, loose fastening or replacement of screws or side wedges

3. The bearing temperature is too high. 1. Insufficient or dirty lubricating grease
