Air compressor common problems

                                                                   Air compressor common problems

The main causes of solenoid valve leakage are:

1. There is dirt inside the solenoid valve.

2. The solenoid valve coil burned due to unstable voltage.

3. There is foreign matter in the silicone inside the one-way valve.

Solution: Open the one-way valve to clean out foreign matter, and smooth the silicone surface with emery cloth.

 two. The cause of the oil leak? Is the product stuck due to lack of oil?

1. The oil drain screw leaks oil, the cylinder gasket leaks oil, and the cylinder screws are not tightened.

2. There are pores or trachoma in the cylinder or box.

3. If the oil drain screw is leaking and the nut is screwed out, the rubber pad inside is damaged or squeezed into the hole.

Solution: Check the location of the oil leak, determine the location of the oil leak, replace/tighten the screws and apply glue or wrap the biological tape.

 three. Oil leakage phenomenon.

1. There is oil leakage from the side of the cylinder head, there is oil in the gas tank, too much oil is added, and the type of oil used is wrong. Failure to maintain the cylinder in time.

Solution:

1. Open the cylinder screws and check whether the piston rings are aligned.

2. Check whether the piston ring is worn.

3. Check whether the cylinder is strained.

 Four. Customers need to change the engine oil once a week. The belt conveyor uses: summer (L-DAA150) compressor oil. In winter (L-DAA100) compressor oil, use No. 68 engine oil for direct-line machines.

 five. What is the cause of air leakage and return of air?

1. It results in slow air intake, frequent work starts, waste of air source, and inability to keep up with air consumption.

2. Main leakage locations: air release valve, drain valve, safety valve, one-way valve, pressure regulating valve, unloading valve, pressure gauge, high-pressure pipe connection, gas storage tank, etc. The glue leaks or is not properly sealed. Stomatal trachoma.

3. Solution:

1. First use a soapy water brush to find the location of the air leak.

2. If the glue leaks, unscrew the screw and wrap it with raw material tape. Apply 704 glue or liquid oxygen glue and screw it back.

3. After the leakage of the gas storage tank is released, repair the leakage location by welding.

 six. The return air from the one-way valve causes excessive air pressure in the box, causing fuel injection.

Reason: 1. There are impurities or foreign matter on the plane of the valve core (silica gel) in the one-way valve or it is uneven.

2. The pressure switch unloading valve is damaged.

 seven. Causes and solutions for blowby gas?

1. Inspection method: Block the air inlet with your hand, which is the position of the muffler. If there is gas coming out, it is blow-by.

2. It will cause the air supply speed to be slow, the pressure to reach a certain level will not rise, the valve plate will burn, the cylinder head temperature will rise, and the life of the main engine will be short.

 reason:

1. There are impurities under the valve plate, and the impurities cause a gap between the valve plate and the valve plate.

2. The use environment is too poor and impurities and dust enter.

3. Not installed properly.

 Solution:

1. Check whether the valve plate is tilted

2. Open the cylinder cover and clean the debris under the valve plate.

3. Reinstall the valve plate.

 eight. Causes of air leakage between cylinder head, valve plate and cylinder:

1. Paper pad breaks

2. The cylinder head screws are not tight

3. The cylinder, valve plate and cylinder head are not flat.

4. There is foreign matter under the paper pad

 Nine. CBB60 is the running capacitor and CD60 is the starting capacitor.

 ten. How to adjust the pressure switch:

Bedroom pressure switch adjustment steps:

1. The flat-shaped iron screw adjusts the take-off pressure. Turn it forward to adjust the take-off pressure and push it up, and twist it counterclockwise to adjust the pressure and push it down.

2. The black slotted plastic screw adjusts the reset pressure. Turn it forward to adjust the pressure upwards, and reverse it to adjust the reset pressure downwards.

3. It is not recommended that customers adjust the pressure of the factory air compressor. The service life will be reduced and the damage will not be covered by the three guarantees.

 eleven. The four major uses of engine oil: lubrication, sealing, cooling and noise reduction

 twelve. The length of the power cord should be about five meters (the power cord should not be too long, as too thin will cause the machine to fail to start, burn, etc.)

 Thirteen. Main reason for no downtime

1. The wire connection is wrong and connected to the motor.

Solution: Connect the wires to L1/L2/L3 of the external protector (after connecting the wires of the new machine, check whether the reversal direction is in the direction of the arrow on the grille. If the direction of rotation is incorrect, swap two wires with L1/L2/L3)

 fourteen. Does not start/difficult to start

1. The power cord connected to the air compressor is too thin, the number of square meters is not enough, or the connected cord is too long, causing too much loss.

2. The pressure switch is not turned on

3. Poor line contact

 Solution:

1. Replace the appropriate square power lead-out wire and the length of the power cord.

2. Check whether the pressure switch is closed properly.

 fifteen. Oil direct line machine is suitable for construction decoration, pneumatic work paint spraying and other places where the source requirements are not high.

16. An air compressor is a gas pressure generating device and a conversion device that converts mechanical energy into gas pressure energy.

Seventeen. According to the working principle, it is divided into:

1. Positive displacement compressor: uses variable volume to increase gas pressure

2. Power compressor: Convert gas kinetic energy into pressure energy, that is, convert gas velocity into pressure.

 eighteen.

According to the exhaust pressure, it is divided into:

Low pressure compressor >0.2>1.0mpa

Medium pressure compressor >1.0>10mpa

High pressure compressor >10>100mpa

Ultra-high pressure compressor >100mpa
