Does your compressor not carry out nicely or make unusual noises? Possibly the compressor does not activate or instantly journeys? Do you need to rapidly check the compressor with out the assistance of others? Listed here are the steps that may make it easier to check the compressor with out dismantling it. These steps don’t require particular instruments to forestall accidents.
First, put together a multimeter, paper, and pen to report the check outcomes. Security first! Earlier than beginning to check, be sure that the facility 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 will 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 have to be changed. Additionally, test the compressor physique for any signal of oil leakage, cracks, or any bodily injury that will point out an issue with the compressor.
Visible Inspection for Bodily Injury
Earlier than performing any electrical or efficiency exams, 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 that will require instant 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 that 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, test 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, test the compressor’s oil degree and situation. Seek advice from the producer’s specs to find out the suitable oil degree for the particular compressor mannequin. A low oil degree can point out leaks or inadequate lubrication, whereas extreme oil can result in foaming and lowered efficiency.
Examine the oil for any discoloration or impurities that will point out contamination. Soiled or discolored oil needs to be changed to forestall injury to the interior elements.
| Oil Situation | Doable Situation |
|---|---|
| Milky or foamy | Water contamination |
| Darkish or gritty | Put on or extreme warmth |
| Metallic particles | Inside part failure |
Stress Gauge Take a look at
A strain gauge check is the most typical strategy to check a compressor. This check entails utilizing a strain gauge to measure the strain of the compressed air within the compressor tank. The strain gauge needs to be related to the compressor tank’s strain port. As soon as the strain gauge is related, the compressor needs to be began and allowed to run till the strain within the tank reaches the specified degree. The strain gauge studying ought to then be taken. The strain studying needs to be inside the producer’s specified vary. If the strain studying is outdoors of the required vary, the compressor is probably not functioning correctly and needs to be serviced.
Extra Particulars
To carry out a strain gauge check, you’ll need the next gear:
| Stress gauge |
| Air hose |
| Couplings |
After you have gathered the required gear, observe these steps:
- Join the strain gauge to the compressor tank’s strain port utilizing the air hose and couplings.
- Begin the compressor and permit it to run till the strain within the tank reaches the specified degree.
- Take the strain gauge studying.
- Evaluate the strain studying to the producer’s specified vary.
- If the strain studying is outdoors of the required vary, the compressor is probably not functioning correctly and needs to be serviced.
Capacitance Analysis
Capacitance analysis is an important facet of compressor testing because it offers 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 sure that the compressor is disconnected from the facility supply earlier than continuing with any exams.
2. Establish the Capacitor
Find the capacitor inside the compressor unit. It is sometimes a cylindrical or rectangular-shaped part 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 (sometimes denoted by a “μF” image).
5. Join the Leads
Join one multimeter result in every capacitor terminal. Guarantee polarity is appropriate, if relevant.
6. Consider Capacitance
Learn the capacitance worth displayed on the multimeter. Evaluate this worth to the producer’s specs for the compressor. The next desk offers a common information for capacitor capacitance values:
| Compressor Sort | Capacitance Vary (μF) |
|---|---|
| Small (<5 hp) | 1.5 – 5 |
| Medium (5 – 10 hp) | 5 – 15 |
| Massive (>10 hp) | 15 – 25 |
A big deviation from the required capacitance worth signifies a possible difficulty with the capacitor or motor.
How To Take a look at The Compressor
There are a couple of easy steps you possibly can observe to check your compressor. First, test the oil degree. The oil needs to be on the “full” mark on the dipstick. If the oil degree is low, add some oil till it reaches the total mark.
Subsequent, test the air strain. The air strain needs to be between 100 and 120 psi. If the air strain is low, alter the strain regulator till it reaches the specified degree.
Lastly, begin the compressor and pay attention for any uncommon noises. For those who hear any unusual noises, cease the compressor and seek the advice of a certified technician.
