The detection of the screw air compressor before starting is very important, it directly affects the later use, so it must be checked before starting the machine. Some people have seen this, they wondered, "Where do you want to start? What places to check?" Don't worry, then, let me explain to you what the screw air compressor should check before starting. .
1. There should be no sundries inside and outside the machine. Flammable and explosive. Corrosive chemicals.
2. Remove the wooden stakes. Live debris such as studs and hoops and supports.
3. Check the setting value of the motor overload relay, check whether the electrical wiring meets the safety regulations, and insulate the nose blood to prevent short circuit. The power switch should be located near the unit.
4. Check the oil and gas pipeline connection is correct, the position of each valve. The status is correct.
5. Turn on the waterway, close the drain valve, and check the air outlet door open. All machinery. The anchor screws of the electrical equipment are complete and firm, the protective cover is complete, and the connecting parts and fasteners are installed normally.
6. Refuel the oil and gas barrels to the upper level of the oil level gauge.
7. Safety interlocking devices such as oil pressure, temperature, differential pressure, solenoid valve, over current, under voltage, etc. shall be qualified according to the technical documents of the equipment.
8. The local control panel and the installed equipment work well and the indicator test is qualified.

Advantages:
1. High strength and stiffness;
2. High impact and notching impact strength;
3. High heat deflection temperature ;
4. Good at dempening;
5. Good glide and limp home characters;
6. Good chemical stability against organic solvents and fuels;
7. Resistant to thermal aging (applicable temperature between -40°C and 90°C;
8. Size alternation by humidity absorption must be considered;
Disadvantages:
1. The water absorption rate of nylon can be as high as 9%;
2. Physical stability is sensitive to temperature and humidity;
3. Dimensional stability is sensitive to temperature and humidity.
Application:
1. Nylon is widely substituted for wear parts of mechanical equipment, or used as quick-wear parts
of equipment instead of copper and alloy;
2. Shaft sleeve, bearing bush, lining, lining plate, gear;
3. Worm gear, roller copper guide rail, piston ring, seal ring, slide block;
4. Spheric bowl, impeller, blade, cam, nut, valve plate,
5. Pipe, stuffing box, rack, belt pulley, pump rotor, etc.
