Description
Technical Field
The invention relates to a multi-way sealing material ejection cylinder of a screw press, which can be widely applied to a material ejection device of the screw press.
Background
The cylinder head of liftout cylinder lower extreme of traditional screw press's ejector is sealed to be used the asbestos board, and the material of asbestos board comprises asbestos, rubber, and sealing performance is poor, and easy gas leakage, the installation is troublesome, and manufacturing cost is high moreover. The L-shaped sealing ring is used for sealing the piston, the piston is only suitable for a low-pressure large-diameter cylinder, the phenomenon of larger gap often occurs, the opening of the lip is less, the contact pressure is insufficient, the sealing is poor, and even the sealing effect cannot be achieved.
Disclosure of Invention
The invention aims to provide a multi-seal material ejecting cylinder of a screw press, which has the advantages of good sealing performance, large bearing working pressure, long service life, safety and reliability.
In order to achieve the purpose, the multi-seal ejecting cylinder of the screw press comprises a cylinder body, a cylinder cover, a cylinder body angle sealing type O-shaped rubber sealing ring, a piston Y-shaped sealing ring, a piston O-shaped rubber sealing ring, a piston rod and a cylinder body O-shaped rubber sealing ring, wherein the cylinder cover is installed on the cylinder body through fastening bolts, the cylinder body angle sealing type O-shaped rubber sealing ring is installed between the cylinder body and the cylinder cover, the piston is installed in the cylinder body, the piston Y-shaped sealing ring is located between the piston and the inner side of the cylinder body and is installed at the lower portion of the piston, the piston O-shaped rubber sealing ring is located between the piston and the inner side of the cylinder body and is installed at the upper portion of the piston, the piston rod is installed on the piston, and the cylinder body O-shaped rubber sealing ring is located between the piston rod and the cylinder body and is installed on the cylinder body.
The invention relates to a multi-way sealing material ejection cylinder of a screw press, wherein a piston Y-shaped sealing ring has the advantages that: simple structure, installation easy maintenance, the leakproofness is good, and is high pressure resistant, high temperature resistant, but automatic compensation after a small amount of wearing and tearing, is particularly suitable for being used for piston seal, long service life.
The invention relates to a multi-seal material ejection cylinder of a screw press, which is characterized in that a cylinder body angle seal type O-shaped rubber seal ring, a piston O-shaped rubber seal ring and a cylinder body O-shaped rubber seal ring have the advantages that: the end face of the sealing ring is small in size, the mounting groove can be designed into an integral groove, the groove is easy to process and mount, and the sealing ring can be sealed in two directions.
According to the multi-seal material ejection cylinder of the screw press, the upper part and the lower part of the cylinder body are respectively provided with the cylinder body O-shaped rubber sealing ring and the cylinder body angle sealing type O-shaped rubber sealing ring, and the sealing elements have good high temperature resistance, high pressure resistance, corrosion resistance and wear resistance. The piston is used for sealing compressed air, plays a role in sealing when the piston reciprocates, and has the advantages of good sealing performance of the cylinder body, large bearing working pressure, durability, long service life and convenience in installation.
According to the multi-sealing material ejection cylinder of the screw press, the piston adopts a double-sealing structure of the Y-shaped sealing ring and the piston O-shaped rubber sealing ring, the Y-shaped sealing ring and the piston O-shaped rubber sealing ring realize the sealing work of the piston together, the double sealing effect is good, and the bearing working pressure is large. In case of sealing failure, the normal work of the cylinder cannot be influenced, and the device is safe and reliable.
Compared with the prior art, the multi-seal material ejection cylinder of the screw press adopts the cylinder body angle seal type O-shaped rubber seal ring at the lower part of the cylinder body, thereby avoiding the defects of poor sealing performance and easy air leakage of the asbestos plate used in the prior art.
Compared with the prior art, the multi-seal material ejection cylinder of the screw press adopts the Y-shaped seal ring, so that the defects that the traditional cylinder only adopts an L-shaped seal ring and is suitable for a cylinder with low pressure and large diameter, the gap is large, the opening of lips is less, the contact pressure is insufficient, and the sealing is poor are avoided.
In conclusion, the multi-sealing material ejection cylinder of the screw press is good in sealing performance, large in working pressure bearing capacity, long in service life, safe and reliable.
