Do you think air compressors are all the same in appearance, but different in price?
Do customers always complain that air compressors often fail?
Today we will fully explain all the details of the air compressors:
Through this article, you can become an expert in this field in 10mins.
The air compressor has many details in each gear.
We divided into three parts to explain and will tell you different between quality and cheap way to produce this machine.
The general structure of the air compressor is divided into:
A(MOTOR)
The key parts are 1. silicon steel sheet and 2. motor coil
1. Silicon steel sheet:
Quality way: Use Silicon steel sheet with good magnetic permeability (silicon steel sheet material certificate can be provided)
Cheap way: Use Steel sheet mixed with Silicon steel sheet, the difference between the two is very large; Or reduce Silicon steel sheet to reduce cost.
2. Motor coil&#;
Quality way: The copper wire used is pure in quality, good in electric conductivity, and the winding turns to meet the standard.
Cheap way: Use inferior copper or aluminum wires, with poor electric conductivity and insufficient winding turns.
The motor combines the above two important keys, the magnetic permeability is poor, and at the same horsepower (HP), the efficiency is not good (ampere is too high) so as to consume electricity.
The electric conductivity is poor, the relative resistance (Ω, Ohm) is high, the service time is long, and it is easy to overheat and even burn down.
B(PUMP)
Key parts include 1. cylinder&#;2. piston&#;3. crankshaft&#; 4. Intake and exhaust valve system&#;5. crankcase 6. cylinder head&#;7. connecting rod&#;8.pulley&#; 9.discharge pipe
1.Cylinder
Quality way: cast iron (FC-25) is used for all materials and the hardness is between 85 and 95 HRB. (Wear-resistant and durable)
Cylinder bore diameter: Cylindricity below 0.01/100mm
(no oil risk)
Cheap way: cast iron with poor quality or aluminum is used, and its processing is unstable, and it is worried about assembly problems. Allowable tolerance is very large.
Therefore, quality is unstable, which often leads to the phenomenon of eating oil. You must pay attention to the amount of oil at any time. When the oil is too small, the piston ring will be injured first, and the efficiency will become poor. The oil will run into the TANK, and the oil content in the air will be too high when it comes out. Or directly lead to piston jam and PUMP scrap.
2. Piston & piston ring
Quality way: using car grade pistons is Taiwan's most professional and well-known piston manufacturer. it provides pistons for major Japanese and European cars (with factory certificates attached). using high-grade pistons, the piston ring on the matching is absolutely first-class. the piston rings are all made of Japanese brand (RIKEN).
Cheap way: The use of pistons and piston rings from unknown manufacturers results in poor circularity, causing the same problems as the cylinders.
3. Crankshaft
Quality way: FCD55 is used as the material, with the emphasis on spheroidizing annealing. The body retains toughness (durable and not easy to break). After precision grinding, the surface is subjected to High-frequency heat treatment, and the surface hardness is sufficient (wear-resistant). After the crankshaft goes through these procedures, the accepted standard of the product warranty material is HRC40-50.
Mainland: FC25orFC30 is used as the material and has not undergone @ Spheroidizing annealing treatment. This material cannot be subjected to High-frequency heat treatment, so the crankshaft has low hardness and tensile strength. After being used for a period of time, it is easy to wear, resulting in a larger gap, abnormal sound and vibration, and further damage.
Difference: Cheap way uses inferior materials
1. The material cost can be saved
2. The processing cost can be saved
The cost of abrasive machining and CNC Lathe depends on the precision and working hours. For the same machining size, the working hours with low hardness are definitely lower. On the contrary, the working hours with high hardness are longer.
And save (Spheroidizing annealing) and (High-frequency heat treatment) costs.
4. Intake and exhaust valve system
Quality way: Intake and exhaust valve system has a patented design. After 30 years of verification, the quality has been able to meet OEM customers. Among them, the valve plates are our special accessories (use UDDEHOLM SS716 420Stainless from ASSAB of Sweden, if you need a material certificate, we are very willing to provide it).
SS716 420Stainless Reference
If you are looking for more details, kindly visit chinese air compressor manufacturers suppliers.
SS716 is a multi-purpose martensitic stainless steel grade designed for the medium and thinner range of various components where toughness and impact strength are essential. UHB Stainless 716 is also used at elevated working temperatures and/or in corrosive atmosphere. The 13% chromium steel is delivered in the hardened and tempered condition and has been proven to offer superior fatigue properties.
Brief introduction: when you see the RPM marked on the MOTOR, such as RPM/min, the motor rotates times per minute, and the rpm is 820/min after pulley reduces the rotation speed, the valve means that the opening and closing of the valve are 820 times the same, which can withstand corrosion, high pressure, high temperature, high-speed vibration and magnetism generated after the operation, but will not be fatigued elastically. this is our patent with ingenious design and high cost of materials.
Cheap way: Intake and exhaust valve system -poorly designed and valve plate-unclear materials often cause valve plate fracture or elastic fatigue in a short period of time.
Brief introduction: when the air compressor purchased by you is used for several months, the pressure rises more and more slowly when it is operated-the valve plate is elastic and tired; Pressure cannot rise during actuation-valve plate breaks. This is the most common problem encountered by many customers.
Summary:
Customers feedback the air compressors in mainland China, often requiring repeated maintenance due to small valve sets. On the contrary, our after-sales quality is superior.
5.Crank case&#;6.cylinder head
Quality way: Good processing will bring a sound body. Many inferior air compressors will run for a period of time. Because the pressure in the box rises, there will always be oil leakage under the crankcase. Oil leakage will occur even when it is installed in the store. These bad conditions have never occurred in our products.
During machining, precise parallelism can improve the service life and efficiency of the piston.
Cheap way: Processing is not accurate enough, and OIL gauge often leaks oil. However, the deviation of the parallelism of the crankcase, after running for a period of time, will cause the power consumption to increase and the efficiency to begin to decrease, often resulting in the damage of the fireplug ring in the light case and the damage of the piston unilaterally in the heavy case.
7.Connecting rod
Quality way: Parallelism mentioned just now is also very important on the connecting rod. It is matched with Babbitt metal Busch with good material to achieve the antifriction effect and smooth operation and save electricity.
Cheap way: Connecting rod doesn&#;t use Abbitt metal Busch
8.Pulley
Quality way: Balance correction, counterweight, small vibration
C(TANK)
Certification needed:
Possess CE CE (Europe), ASME (North America), CRN (Canada)
Assist Australian OEM customers through AS-3
Assist Japanese OEM customers to pass JIS B

Sollant screw air air compressor
The working principle of a screw air air compressor is pretty simple.
This type of air compressor depends on male and female rotors to compress the air.
The function of the male rotor is to drive the female rotors.
The screw air air compressor technology is usually used in an oil-injected screw air air compressor.
For a dry screw air air compressor, a timing gear drive is used to drive both the male and the female rotors.
Otherwise, the basic working principle of a screw air compressor is the male and female rotors rotate in opposite directions.
In a screw air compressor, one of the poles is driving shaft, and the other is driven shaft. The driving shaft is directly linked to the driven shaft utilizing timing gears which help to coordinate paces of both the shafts. The driving shaft is fueled by an electric motor generally. The two shafts are encased in an impenetrable casing.
To start the operation off, the suction valve is opened to permit air suction. At that point, the motor is turned on to the shaft.
The secondary shaft, in this way, additionally begins rotating opposite to the driving shaft due to timing gears.
The air enters the hole between the two screw airs cut over the poles. As the two screw airs turn the opposite way, the air gets caught ready between the two screw airs.
The hole between the two screw airs diminishes bit by bit from suction end to conveyance end, which prompts an increase in the pressure of air.
Likewise, due to screw air activity, the air moves from the suction end to the conveyance end. At the point when the compacted air arrives at the conveyance end, it goes through the conveyance valve to the capacity tank.
Additionally, during the compression process, cold water is consistently poured around the packaging, which trades heat with the hot compacted air.
The purpose of this is the productivity of any pressure procedure will be most elevated on the off chance that it is done isothermally in contrast with adiabatically or polytropically.
The speed at which the rotors are rotating is optimized. This minimizes the mechanical loss of the compressor due to heat and friction.
Since screw air compressors don&#;t have valves, they are capable of working at very high speeds hence displacing large volumes of air.
Even with large volumes, the rate of flow can still be controlled at the exit points.
