How AC Compressor Work?

Ningbo Anchor is the professional auto ac compressor manufacturer, we can offer you high quality and reliable service. Now let me introduce the abnormal noise of automobile air-conditioning compressors.

We can’t generalize about the problem of abnormal noise of automobile air-conditioning compressors, because abnormal noises are just performance, but there are many reasons for abnormal noises.Therefore, after abnormal noises of automobile air-conditioning compressors, we must first investigate and determine the cause Before finally finding a solution.

Let’s analyze the specific causes of abnormal noise of automobile air-conditioning compressors

Abnormal noise when the compressor is running mainly occurs in the cylinder and crankcase. The main causes of cylinder abnormal noise (knock sound) are:

1. The top of the piston collides with the exhaust valve, that is, the clearance is too small, and a “cylinder knock” phenomenon occurs. Can be increased by increasing the thickness of the gasket on the contact surface of the two

Large clearance to eliminate the “knock knock” phenomenon.

2. The valve plate of the suction and exhaust valve is damaged or broken due to serious wear, poor material and improper operation. Treatment method: replace the valve.

3. The piston ring is worn or stuck. Treatment method: replace the worn piston ring. Strengthen lubrication.

4. Compressor fluid knocking sound, crankshaft toggle, or the big head of connecting rod splashing oil produces “oil knocking” sound. Need to find out the reason and rule out immediately.

5. The tightening screw of the valve disc or the nut on the piston connecting rod is loose. Just tighten.

Analysis of the causes of abnormal noise in the compressor crankcase:

1. The gap between the connecting rod big-end bearing bush and the crank, and between the crank and the main bearing is too large, the gap should be adjusted, and the bearing bush should be replaced if necessary.

2. The amount of lubricating oil in the bearing is insufficient or impurities are mixed in the lubricating oil. Check the oil circuit, remove impurities or replace the lubricant.

3. The connecting rod nut is loose; treatment method: re-tighten.

4. The loose fit between the flywheel and the shaft requires readjustment or repair.

The abnormal noise of automobile air-conditioning compressor, in fact, there are many reasons for abnormal noise of automobile air-conditioning compressor.

It is recommended that you go to a professional location.

If it is only when the air conditioner is turned on, the possible causes are as follows:

Too much or too little refrigerant charge, the flow sound generated when passing the expansion valve; the amount of lubricating oil inside the compressor is small, and the friction caused by insufficient lubrication

Sound; the compressor produces abnormal sounds that resonate with other parts of the wheel system at a certain speed; the suction and exhaust pulses of the compressor itself are relatively large, and the generated pulses

The motion is transmitted to the air-conditioning box through the air-conditioning pipeline and amplified to produce abnormal sound.

Rules of the road; How well do you know them?

Learning to drive is one of the most difficult, yet rewarding things that you can do. Being an inexperienced driver and sitting behind the wheel for the first time can be one of the most daunting and frightening things. After hours of stressful driving lessons, theory mock-up tests and the dreaded driving test itself, you’re ready to hit the road solo. There is no better feeling than being able to pick up your keys, get in your car and drive around freely to your hearts content. It doesn’t take long to turn from a shy driver to an extremely confident one who knows the roads back to front and all the rules that go with it… or so you might think.

When it comes to driving, safety should always be the number one priority. Wherever you drive, the basic rules will always be the same.

Follow the speed limits

Speed limits are there for a reason, they are not placed there just as a recommendation. Did you know that inappropriate speed contributes to around 11% of all injury collisions reported to police, 15% of crashes resulting in a serious injury and 24% of collisions that result in a death?

Don’t run a red light

Many drivers will attempt to run through an amber light that is just about to change to red. This can be a dangerous game, however, if the traffic light has a camera attached to it and you’re even just a fraction of a second too late, the camera will flash and you’ll be receive a hefty fine and potentially points on your license – which is never good for car insurance renewals!

Keep a safe following distance

You must drive a safe distance behind a vehicle travelling in front of you. This will give you enough time to react and break safely if the driver in front has to break suddenly for any reason. Following another vehicle too closely is known as tailgating, which is a primary reason for rear end crashes. It’s recommended to keep a 3 second distance between you and the car in front of you in dry conditions, 4 seconds for wet conditions!

Always wear a seatbelt

Do you always wear your seatbelt? Well, you should. Even if you are only travelling a short distance and think you have no chance of crashing. It’s always better to be safe than sorry. Seatbelts are pivotal to keeping you safe on the road; they dramatically reduce the chance of death and serious injury. Front seat passengers and drivers who wear their seatbelts reduce the risk of death by 45% and cut the risk of serious injury by 50%. People not wearing a seatbelt are 30 TIMES more likely to be ejected from a vehicle during a crash. So before you turn on that ignition, strap up!

To keep up with safety standards, the rules of the road are always changing in order to deliver the safest possible experience for drivers, passengers and pedestrians. With all these constant changes it can be overwhelming to stay on top of them all. There may be some situations where you’re not even aware that you’re breaking the law!

Did you know that it could be our four legged furry friends that could land you in the dog dirt? You may often see dogs hanging out the window, tongues out and enjoying life whilst they cruise down the road with their owners. However, there is a correct way you should be driving with your dog in the car and you could be breaking the law if you choose to ignore these rules. Your dog should be retrained in the car so they are not to cause a distraction when you are driving. With this being put into action the dog should be harnessed in a way that will not cause injury to you or him in case you were to come to a sudden stop. Failure to comply could land you a hefty £5000 fine. Tyre Pros have published a handy article of all the dos and don’ts of the road that involve your dog that are worth checking out!

Which Is Best – Steel or Aluminum Hitch Cargo Carriers?

When you have a good receiver hitch cargo carrier attached to the back of your car, it becomes extremely easy to transport extra luggage and stuff. Things like beach chairs, tree stumps, tools, garden supplies, cooler, luggage, diving gears, trash cans and every other thing that won’t fit in your car or SUV can fit on a cargo carrier.

There are two types of material used in cargo carriers: steel and aluminum. There are reasons some folks choose one over the other. If you are looking to buy a hitch mounted cargo carrier and you are confused on which one to choose, here is what you need to know.

Steel Hitch Cargo Carriers

Pros: If you want to have a receiver hitch cargo carrier that is sturdy and able to withstand highways that are not so smooth or even mountainous terrain, then you need a steel hitch cargo carrier. Many car owners trust this carrier because it is capable of hauling whatever they require for their outdoor adventure.

Apart from being very sturdy, steel hitch cargo carriers are known to have massive load bearing capabilities. Regardless of what is being placed on the tray, they can secure them thereby making them a perfect match for hauling serious effects from camping trips. However, they have their shortcomings.

Cons: One major area of concern for most customers is weight. These cargo carriers are generally known to be weighty. These carriers can weight up to 60 pounds. Also, they are not corrosion resistance and this often affects their overall appearance. As a result, must customers may be forced to spray paint their carrier every couple of years.


Aluminum Hitch Cargo Carriers

Pros: Weight is simply one of the most prevalent advantages of the aluminum hitch cargo carrier over the equivalent steel version. This type of trailer hitch cargo carrier is generally known to be lightweight. As a result, little effort is required to lift and install it to the back of the car. Even a single person can do this just fine.

The aluminum hitch cargo carrier tries to eliminate the need of paint or fancy coating to protect it because it doesn’t rust. These carriers are less expensive as their steel counterparts. There are really no disadvantages with this type of cargo carrier. It will both be able to carry items up to its rated capacity.

Both steel and aluminum hitch cargo carriers will get the job done in nearly all cases.

How to maintain critical car parts

If you own a newer car model then it may need less maintenance that what some of the old models require. By the old models we mean the models that were manufactured a decade or so back. However this should not give you a sense of security as there are many things even in the new models that need to be looked after on a regular basis. In this article we will discuss about how to maintain some of the critical car parts.

Oil –The engine oil of your car ensures that your engine works smoothly year on year without much maintenance. Over prolonged years of usage, the gases that come from cylinders and also small bits of the metal pollute the oil and thus its effectiveness as a lubricating agent gets reduced. Heat also reduces its thickness and viscosity. When the oil becomes thin it will not lubricate the engine efficiently. Hence if you have an old car, then consider changing the oil of the car after every 4000-5000 mile of ride.

Suspension- A complete visual inspection is the best thing that can be done for proper maintenance of the suspension. It can help you in pre identification of any eminent failure. Ideally with every oil change the suspension should be also inspected. Try pushing the vehicle up and down and look for the number of bounces it makes. If it makes more than two bounces then it could mean that shocks have become old and worn out. If your vehicle has undergone suspension modification then ideally you should check the suspension more often because any change in suspension disturbs the angle of the suspension components which causes them to wear out more quickly. You may also want to upgrade your car with best 4X4 suspension.

Tires- Tire is the part of the car which is most susceptible to wear and tear. Like the brake pads, these have built in indicators that tread with the ridges which are 1/15 of an inch high. When these ridges become flat, you should ideally get your tire checked for a change. Otherwise also you should have the car tire checked every month for wear and tear.

Apart from other mentioned components there are many other parts that need a regular preventive maintenance such as the pads, brushing components, engine valves, etc. You cannot ignore maintenance of any of the above mentioned parts if you want your car to last longer. Preventive maintenance will not only help your car last longer but also reduce the cost of breakdowns.

How to Decide the Size of the Car Wipers

Car’s windshield commonly includes wiper blades which help to clear the wind screen from liquid or other things which may hinder driver’s vision while riding the car. Each of the wiper blades will work in a smooth semi-circle motion from its arm point. The wiper blades not only make the view right before the driver and front passenger clearer but also able the clear the rear window as well when the care features with rear wiper blades. Even though car has been equipped with wipers, there is always an area on that window which doesn’t get approached by the blades. Those areas such as the passenger’s side top corner and driver’s side bottom corner. If this happens to your car perhaps you need to get new wiper size blades which can approach more to the window glass. If you plan to replace the blades, you need to consider the guides in order to get the right size of wipers.

Selecting the Best Size of Wiper Blades   

Each car commonly comes with specific wiper blades. There are types of car which provide the similar side wiper blades for both driver and passenger. However, for other cars they might be particularly unlike. The right size of the wiper that you should give to the car is actually the one which is chosen for appropriate accessories as well as to clear as much section as possible on the wind screen of the car. If you swap the wiper blades on the windshield with the larger ones, the problem which might encounter is the one or both of the wipers will either dangle on the glass screen or smash the upper trim of windshield when it is positioned vertically. This condition can result on risk the less durable use of wipers. Another problem of too long wipers is there will be area on the window which doesn’t get cleaned properly when the blades are not purged the glass screen. Overly long size also can peril the wiper blade themselves since it can knock each other, twisted, and harm the parts of the blades such as their arms, motor, as well as transmission.

On the other hand, if wiper blade size appears to be smaller, then there might be some problems raise up too. For instance, when you put smaller wipers on the car’s windshield that it will be easier for you to spot large area on it which aren’t cleared probably including the most important viewing section. You need to make sure that you change the blade wipers with the size which has been specified by the manufacturer. It is important to convince the appropriate fitment and lowering the risk find. You are able to look for the size of the car wipers through the car manual or find it online since there are specific sites which provide recommended size of wipers blade for all well-known car manufacturers. For example, you will know that Hyundai Tucson 2015 will require wiper size containing 24 inch for the driver side and 16 inch for the passenger side.
