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 wish to rapidly check the compressor with out the assistance of others? Listed below are the steps that may assist you 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, ensure 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 probably 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 must be between 1 and 10 ohms. If the resistance is simply too excessive or too low, it signifies an open or quick circuit within the motor windings, and the compressor should be changed. Additionally, test the compressor physique for any signal of oil leakage, cracks, or any bodily harm which will point out an issue with the compressor.
Visible Inspection for Bodily Harm
Earlier than performing any electrical or efficiency exams, it is essential to visually examine the compressor for any indicators of bodily harm that would point out potential points. This visible evaluation serves as an preliminary screening and helps determine apparent issues which will require quick consideration.
Exterior Parts
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 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 parts, test the compressor’s oil degree and situation. Discuss with 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 decreased efficiency.
Examine the oil for any discoloration or impurities which will point out contamination. Soiled or discolored oil must be changed to forestall harm to the inner parts.
| Oil Situation | Potential Problem |
|---|---|
| Milky or foamy | Water contamination |
| Darkish or gritty | Put on or extreme warmth |
| Metallic particles | Inner element failure |
Strain Gauge Check
A strain gauge check is the most typical solution 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 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 degree. The strain gauge studying ought to then be taken. The strain studying must be inside the producer’s specified vary. If the strain studying is exterior of the desired vary, the compressor is probably not functioning correctly and must be serviced.
Further Particulars
To carry out a strain gauge check, you have to the next gear:
| Strain gauge |
| Air hose |
| Couplings |
Upon getting gathered the mandatory 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.
- Examine the strain studying to the producer’s specified vary.
- If the strain studying is exterior of the desired vary, the compressor is probably not functioning correctly and must be serviced.
Capacitance Analysis
Capacitance analysis is an important facet 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 make sure that the compressor is disconnected from the facility supply earlier than continuing with any exams.
2. Determine the Capacitor
Find the capacitor inside 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 Kind | Capacitance Vary (μF) |
|---|---|
| Small (<5 hp) | 1.5 – 5 |
| Medium (5 – 10 hp) | 5 – 15 |
| Giant (>10 hp) | 15 – 25 |
A big deviation from the desired capacitance worth signifies a possible situation 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, test the oil degree. The oil must 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 must be between 100 and 120 psi. If the air strain is low, modify the strain regulator till it reaches the specified degree.
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 certified technician.
