卸料閥是飼料機械上的重要部件，只有更好的保養才能更好的發揮其作用。那么應該如何對卸料閥進行保養呢？
1、卸料閥在出廠前以注足潤滑油與潤滑脂，在正常使用6個月后傳動及軸承部位應補充或是更換油脂,如果安裝環境是在溫度較高或是灰塵過多時應縮短換油時間。
Discharge valve at the factory to note a little oil and grease, in normal use, six months after the drive and bearing parts should complement or replace the oil, if the installation environment is at higher temperatures or excessive dust should shorten oil change time.
2、卸料閥適用于連續工作允許反正運轉，在運行過程中如果出現沿軸向漏風或是漏灰現象，可禁錮壓料蓋的螺絲或是從新更換石棉盤根后在壓緊料蓋即可。
Discharge valves are suitable for continuous operation allows the operation anyway, during operation, or if there is leakage gray axial leakage phenomenon, can imprison binder cover screws or new replacement asbestos packing materials in the cover can be pressed.
3、如果卸料閥所輸送的物料黏度過大，容易造成設備的超載運行簡易用戶安裝過載保護裝置或是更換大功率的電機。
If the material is conveyed discharge valve viscosity is too large, easily lead to overload operation simple user equipment installation overload protection device or replace power motors.
4、各種型號卸料閥的內部結構都相同,拆裝順序與裝配工藝也基本相同，在運輸卸料器過程中應保持平穩避免碰撞，造成殼體和電機的損壞。
Various internal structures are the same type discharge valve, disassembly sequence and assembly process is basically the same, in the course of transportation unloader should remain stable to avoid a collision, causing damage to the housing and the motor.
