Does your compressor not carry out properly or make unusual noises? Perhaps the compressor does not activate or immediately 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 show you how to take a look at 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 document the take a look at outcomes. Security first! Earlier than beginning to take a look at, ensure that the ability to the compressor is turned off. Be sure 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 seemingly 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 traditional resistance studying must be between 1 and 10 ohms. If the resistance is just too excessive or too low, it signifies an open or quick circuit within the motor windings, and the compressor have to 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 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 establish apparent issues which will require speedy consideration.
Exterior Elements
Start by analyzing the compressor’s exterior parts, 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 sure 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 parts, examine the compressor’s oil stage and situation. Seek advice from the producer’s specs to find out the suitable oil stage for the precise 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 must be changed to forestall injury to the interior parts.
| Oil Situation | Doable Subject |
|---|---|
| Milky or foamy | Water contamination |
| Darkish or gritty | Put on or extreme warmth |
| Metallic particles | Inner element failure |
Stress Gauge Take a look at
A strain gauge take a look at is the most typical solution to take a look at a compressor. This take a look at includes utilizing a strain gauge to measure the strain of the compressed air within the compressor tank. The strain gauge must be related to the compressor tank’s strain port. As soon as the strain gauge is related, the compressor must be began and allowed to run till the strain within the tank reaches the specified stage. The strain gauge studying ought to then be taken. The strain studying must be throughout the producer’s specified vary. If the strain studying is outdoors of the required vary, the compressor is probably not functioning correctly and must be serviced.
Extra Particulars
To carry out a strain gauge take a look at, you will want the next gear:
| Stress gauge |
| Air hose |
| Couplings |
After you have gathered the mandatory gear, comply with 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 stage.
- 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 must be serviced.
Capacitance Analysis
Capacitance analysis is an important 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
At all times be sure that the compressor is disconnected from the ability supply earlier than continuing with any exams.
2. Determine the Capacitor
Find the capacitor throughout the compressor unit. It is sometimes 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 (sometimes 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. Evaluate this worth to the producer’s specs for the compressor. The next desk supplies a normal 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 required capacitance worth signifies a possible problem with the capacitor or motor.
How To Take a look at The Compressor
There are a couple of easy steps you’ll be able to comply with to check your compressor. First, examine the oil stage. The oil must 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 strain. The air strain must be between 100 and 120 psi. If the air strain is low, modify the strain regulator till it reaches the specified stage.
Lastly, begin the compressor and pay attention for any uncommon noises. In the event you hear any unusual noises, cease the compressor and seek the advice of a professional technician.
