Piston air compressor safety protector

Abstract

The invention relates to the field of air compressors, in particular to a piston air compressor safety protector. The piston air compressor safety protector is characterized by comprising a body sleeve, an ejector rod, a trigger cap, a piston, a spring and a microswitch, the piston is arranged in the body sleeve, at least two sealing rings are arranged between the outer surface of the piston and the inner wall of the body sleeve, the top of the piston is connected with one end of the ejector rod, the spring is sleeved on the ejector rod, an adjusting gland is arranged at the top of the body sleeve, the other end of the ejector rod extends out of the adjusting gland, the microswitch is arranged right above the ejector rod, the bottom of the piston is connected with one end of the trigger cap, a transition sleeve is arranged between the trigger cap and the body sleeve, the outer surface of the transition sleeve is provided with a thread, the other end of the trigger cap is provided with a trigger plane perpendicular to the central axis of the trigger cap, and the outer diameter of the transition sleeve is matched with a mounting hole between two suction and exhaust valves on a cylinder cover. Compared with the prior art, the piston air compressor safety protector has the advantages that the service lives of parts of a compressor are obviously prolonged, and the working efficiency of the compressor is improved.

Description

technical field [0001] The invention relates to the field of air compressors, in particular to a safety protector for piston air compressors. Background technique [0002] Air compressors are indispensable machinery and equipment in modern industrial and agricultural production, especially piston air compressors are more widely used. There are two types of lubrication: "with oil" and "without oil". Take the 40 cubic piston oil-free air compressor as an example: each compressor has 16 sets of suction and discharge valves. Frequent start-up work in the state, the valve plate often breaks, and the broken valve plate falls between the piston and the cylinder head. Under the high-speed reciprocating impact of the piston, the broken valve plate penetrates the surface of the aluminum piston body, causing damage to the piston. After the valve body of the suction and exhaust valve is hit and broken by the broken valve plate, the volume of the broken valve body is relatively large, ...

AI Technical Summary

Problems solved by technology

After several rounds of reciprocating movement of the piston, the cylinder head and piston will be damaged, and in severe cases, the cylinder block and crankshaft connecting rod will be scrapped. Therefore, the average service life of the suction and exhaust valves is only 30 days, and the average service life of the piston is only 30 days. 6 months, the average life of the cylinder head is only 2 years

The current air compressors do not have protection devices for such failures. In order to avoid such accidents, we can only rely on the operator's operating experience and the sense of responsibility of the maintenance personnel.
