Does your compressor not carry out nicely or make unusual noises? Possibly the compressor does not activate or all of a sudden journeys? Do you need to shortly take a look at the compressor with out the assistance of others? Listed below are the steps that may enable you to take a look at the compressor with out dismantling it. These steps don’t require particular instruments to stop accidents.
First, put together a multimeter, paper, and pen to file the take a look at outcomes. Security first! Earlier than beginning to take a look at, be sure that the ability to the compressor is turned off. Be certain that the capacitor is discharged by shorting its terminals with an insulated screwdriver. Placed on security gloves and glasses to guard your self.
A defective compressor will possible trigger the motor to overheat and should trigger a tripped breaker. To check the compressor motor, use a multimeter to measure the resistance between every of the three terminals. A standard resistance studying needs to be between 1 and 10 ohms. If the resistance is simply too excessive or too low, it signifies an open or brief circuit within the motor windings, and the compressor should be changed. Additionally, examine the compressor physique for any signal of oil leakage, cracks, or any bodily injury which will point out an issue with the compressor.
Visible Inspection for Bodily Injury
Earlier than performing any electrical or efficiency checks, it is essential to visually examine the compressor for any indicators of bodily injury that would point out potential points. This visible evaluation serves as an preliminary screening and helps determine apparent issues which will require rapid consideration.
Exterior Elements
Start by inspecting the compressor’s exterior elements, such because the корпус, клеммы, проводка, и любые внешние трубопроводы. Search for cracks, dents, or corrosion which will have occurred throughout dealing with or set up. Be certain that all connections are safe and free from unfastened wires or frayed insulation. Additionally, examine for any unfastened or lacking bolts or brackets that would have an effect on the compressor’s stability and efficiency.
Compressor Oil
Along with inspecting the exterior elements, examine the compressor’s oil stage and situation. Discuss with the producer’s specs to find out the suitable oil stage for the particular compressor mannequin. A low oil stage can point out leaks or inadequate lubrication, whereas extreme oil can result in foaming and decreased efficiency.
Examine the oil for any discoloration or impurities which will point out contamination. Soiled or discolored oil needs to be changed to stop injury to the interior elements.
| Oil Situation | Attainable Problem |
|---|---|
| Milky or foamy | Water contamination |
| Darkish or gritty | Put on or extreme warmth |
| Metallic particles | Inner element failure |
Strain Gauge Check
A stress gauge take a look at is the commonest option to take a look at a compressor. This take a look at entails utilizing a stress gauge to measure the stress of the compressed air within the compressor tank. The stress gauge needs to be linked to the compressor tank’s stress port. As soon as the stress gauge is linked, the compressor needs to be began and allowed to run till the stress within the tank reaches the specified stage. The stress gauge studying ought to then be taken. The stress studying needs to be throughout the producer’s specified vary. If the stress studying is exterior of the desired vary, the compressor will not be functioning correctly and needs to be serviced.
Extra Particulars
To carry out a stress gauge take a look at, you will have the next tools:
| Strain gauge |
| Air hose |
| Couplings |
After getting gathered the mandatory tools, observe these steps:
- Join the stress gauge to the compressor tank’s stress port utilizing the air hose and couplings.
- Begin the compressor and permit it to run till the stress within the tank reaches the specified stage.
- Take the stress gauge studying.
- Examine the stress studying to the producer’s specified vary.
- If the stress studying is exterior of the desired vary, the compressor will not be functioning correctly and needs to be serviced.
Capacitance Analysis
Capacitance analysis is a vital side of compressor testing because it supplies insights into the situation of the compressor’s motor and capacitor. The next steps define the method of capacitance analysis:
1. Security First
All the time be certain that the compressor is disconnected from the ability supply earlier than continuing with any checks.
2. Determine the Capacitor
Find the capacitor throughout the compressor unit. It is usually a cylindrical or rectangular-shaped element with two terminals.
3. Discharge the Capacitor
Utilizing an insulated screwdriver, briefly contact each capacitor terminals collectively to discharge residual voltage. That is important for security.
4. Set Up the Multimeter
Set the multimeter to the capacitance measurement mode (usually denoted by a “μF” image).
5. Join the Leads
Join one multimeter result in every capacitor terminal. Guarantee polarity is right, if relevant.
6. Consider Capacitance
Learn the capacitance worth displayed on the multimeter. Examine this worth to the producer’s specs for the compressor. The next desk supplies a basic information for capacitor capacitance values:
| Compressor Sort | Capacitance Vary (μF) |
|---|---|
| Small (<5 hp) | 1.5 – 5 |
| Medium (5 – 10 hp) | 5 – 15 |
| Giant (>10 hp) | 15 – 25 |
A major deviation from the desired capacitance worth signifies a possible challenge with the capacitor or motor.
How To Check The Compressor
There are a number of easy steps you may observe to check your compressor. First, examine the oil stage. The oil needs to be on the “full” mark on the dipstick. If the oil stage is low, add some oil till it reaches the complete mark.
Subsequent, examine the air stress. The air stress needs to be between 100 and 120 psi. If the air stress is low, modify the stress regulator till it reaches the specified stage.
Lastly, begin the compressor and hear for any uncommon noises. If you happen to hear any unusual noises, cease the compressor and seek the advice of a professional technician.
