Air compressor body crack reason and the method of examination
Author: www.dg-zhihe.com      Release Date:2012/11/30      View Count:4175
 

According to the annals and mechanical and electrical equipment limited company technical personnel to understand, air compressor body cracks are common reasons are as follows:

1, as a result of casting internal stress generated when, in use gradually expanded significantly after vibration;

In 2, the cooling water in the cylinder head, in the winter without freezing time after stopping water;

In 3, due to the occurrence of mechanical accidents caused by ruptured, such as a piston, connecting rod screw break, causing the rod broken off, or on the crankshaft balance iron fly out the broken body or a valve parts off bad cylinder head top.

Check the air compressor body crack method has the following two kinds:

1, kerosene penetrant inspection method:

Check, first soaked with kerosene cotton head wiping body and the cylinder head with suspected crack place, then dry cotton yarn head kerosene wipe, and immediately coated with powder, then, crack place, kerosene and then penetrate into powder, crack location and length is clearly displayed.

2, water pressure testing method

Hydrostatic pressure method is used to improve the cooling water pressure method to check the crack location, general business can use ordinary pressure hand pump system simple equipment to check. Check, first the body or cylinder head water pipe joint managed to hold, to which a water pipe joint with a rubber tube with a water outlet connected, body size of plane should use special cover plate, so that the cooling water can not spill. Then turn on the switch pressure water pump, so that water enters into the cooling water jacket. The switch will switch off after the water again, continue to pressure pump, the pressure gauge pointer to 3-4 atmospheric pressure is stopped when the water supply. Then, carefully view the air compressor cylinder head body, the upper and lower water leakage or seepage and has no phenomenon.

Reminder.

And the mechanical and electrical equipment Limited sincere intention to recommend air compressor water heater, air compressor waste heat recovery equipment, as long as you plant air compressor, can 0 operation cost of producing hot water and heating.

( this article mainly analyzes the compressor body crack reason and the method of examination, but in actual problem solving process for reference only. )
