Embodiment Construction

[0014] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0015] exist figure 1 , 2 Among them, the two-way internal sealing structure of the mechanical vibrator mainly includes a spring 2, a piston 3, a piston ring 4, and a two-way Y-shaped sealing ring 5. The spring 2 is installed at the bottom of the piston guide cylinder 7. With the help of the compressibility of the spring, When the piston guide cylinder 7 is installed, the spring 2 is allowed to have a certain compression range, which is very convenient during installation, much simpler and easier than the fixed installation; the piston is installed in the piston sleeve 6, and it is installed on the left side of the spring And connected closely with the spring. In the working state, due to the pre-tightening force of the spring 2, the inner surface of the piston is tightly pressed against the end surface of the piston rod 1, which acts as an ...

Abstract

The invention relates to a bidirectional internal sealing structure of a mechanical vibrator. The bidirectional internal sealing structure of the mechanical vibrator comprises a spring, a piston and a Y-shaped sealing ring, wherein the piston is arranged on one side of the spring and is in tight contact connection with the spring; an annular groove and a rectangular groove are formed on the piston; the Y-shaped sealing ring is arranged in the rectangular groove of the piston; the Y-shaped sealing ring is a bidirectional Y-shaped sealing ring consisting of two Y-shaped sealing rings; directions of lips of the two Y-shaped sealing rings are opposite; and the bidirectional Y-shaped sealing ring is sealed at the piston to achieve a bidirectional self-sealing effect, so as to improve a sealing effect of the bidirectional Y-shaped sealing ring between the piston and a piston sleeve. The bidirectional internal sealing structure of the mechanical vibrator has the main advantages that: the bidirectional Y-shaped sealing ring, a piston ring, the spring and other components act together to form a high-efficiency internal sealing system, so that the internal sealing performance of the mechanical vibrator is effectively improved and the service life of the mechanical vibrator is prolonged.

Description

technical field [0001] The invention relates to a bidirectional inner sealing structure of a mechanical rapper. Background technique [0002] Internationally, clean, safe and low-pollution clean coal gasification technology has developed rapidly in the 1980s. Coal gasification is to convert solid fuel into gaseous products, fully reflect the utilization value of coal resources, improve the comprehensive utilization efficiency of coal resources, and reduce pollutant emissions in the process of coal use. my country's "coal-rich, oil-shortage" resource distribution determines that coal will be the main primary energy source for a long time in the energy consumption structure. The use of coal gasification technology to protect the environment and save resources has attracted great attention. The national "Eighth Five-Year Plan" and "Ninth Five-Year Plan" clearly pointed out that clean coal technology is an important means of rational and effective development and utilization of...
