Bottom pressure-resistant rotary valve double-hole circular discharger volumetric with suction port bulk cement,Usage precautions:1、 Before using the star-type discharger, check the quantity and type of lubricating oil in the gearbox. Replace with new oil after one month of operation, and then change the oil once a year thereafter.2、 Connect the air source interface and check if it is blocked by foreign objects to ensure it is clean and unobstructed;3、 Before using the star-type discharger, ensure that the rotor rotates clockwise (viewed from the extended shaft end of the gearbox, consistent with the arrow on the sprocket cover);4、 Before using the star-type discharger, open the sprocket cover to check the chain tension and inspect it regularly during operation; also apply suitable grease to the chain and sprocket;5、 Throughout the use of the discharger, adjust the pressure reducing valve so that the pressure at the seal is preferably 0.05MPa higher than the material pressure inside the valve body; this gas should be oil-free, dry compressed air;6、 During the entire use of the star-type discharger, the air source at the seal must always be present; it can only be turned off after confirming that the valve has stopped operating;

Common faults: 1. During transportation and installation of the star-type discharger, keep it stable and avoid collisions to prevent shell breakage or deformation. 2. Before leaving the factory, the gearbox is filled with No. 0 grease, and the ash discharge valve is filled with lithium-based grease. Within 6-10 months of use, the transmission and bearing components should be replenished or replaced with grease. If the ambient temperature is high, humid, or there is excessive dust in the air, the oil change interval should be appropriately shortened. 3. During use, if there is air or ash leakage along the axial direction, tighten the material compression cover. 4. During operation, avoid overload operation caused by large material particles or strong adhesion, or equipment jamming or motor short circuits due to foreign objects left in the dust collector, which may damage the equipment. It is recommended that users promptly inspect and install overload protection devices. 5. This machine is suitable for continuous operation and allows forward and reverse rotation. 6. When assembling the output shaft and input shaft of the discharger with other parts, do not strike or hammer directly to avoid damage.Bottom pressure-resistant rotary valve double-hole circular discharger volumetric with suction port bulk cement.
