Respirator and reducer

Abstract

The invention discloses a respirator and a speed reducer. The respirator comprises a piston cylinder body (1) and a piston (2). The piston cylinder body (1) is provided with a piston cavity. The piston (2) can be arranged in the piston cavity in a sliding mode. One end of the piston cylinder body (1) is provided with a respirator connecting opening communicated with the piston cavity. The other end of the piston cylinder body (1) is provided with gas exhaust holes (3) and a gas exhaust collision pin (4). The piston (2) is provided with a valve core (5) which corresponds to the position of the gas exhaust collision pin (4) and is in a normally closed state. Gas introduced through the respirator connecting opening can drive the piston (2) to move towards the gas exhaust collision pin (4), so that a gas exhaust core rod of the valve core (5) collides with the gas exhaust collision pin (4) so as to break over the valve core (5). According to the respirator, gas exhaust and compensation can be conducted, and meanwhile, air containing water from the outside world is prevented from entering equipment where the respirator is installed through the respirator.

Description

technical field [0001] The invention relates to the field of respirators, in particular to a respirator. Background technique [0002] The respirator is a protective device developed to protect various lubricating equipment against lubricant pollution. It is widely used in gear boxes, reducers, hydraulic equipment, oil storage tanks, transformers and other equipment. [0003] At present, in order to ensure the balance of pressure inside and outside the gear box and prevent oil leakage or damage to the oil seal caused by the pressure in the gear box being too high or too low, the respirator used by the reducer in the power plant is mostly a silicone respirator, and the respirator shell is made of elastic polycarbon The plastic shell has a filter screen and granular silica gel inside to form a comprehensive filter screen. The structure of this type of respirator is a two-way flow structure (that is, during the operation of the reducer, the oil and gas inside the reducer can b...

AI Technical Summary

Problems solved by technology

The structure of this type of respirator is a two-way flow structure (that is, during the operation of the reducer, the oil and gas inside the reducer can be discharged into the atmosphere through the respirator, and the atmosphere can also pass through the respirator when the load of the reducer is low or the process is out of service. However, for some special environments with high humidity in the power plant, such as the air-cooled fan reducer, due to the special working conditions of the air-cooling system, the system is required to be equipped with a flushing and spraying system. In the case of a shower system, due to the increase in air humidity outside the respirator, the high-humidity air sucked into the gearbox will accelerate the failure of the silica gel inside the respirator, and if the expired silica gel is not replaced in time, it will eventually cause the lubricant inside the equipment Pollution, excessive water content, and reduced lubricating ability of the lubricating oil, so that the lubricating oil needs to be replaced frequently, and even the equipment is damaged due to the water content of the lubricating oil
