Air End Differences between various main air compressor brands
Everyone says that the core component of the screw air compressor is the screw element. It should be said that if the screw air end is selected, you are half done?
Because the main parameter that affects the performance of the screw air compressor is the screw element, the rest of the connection methods, three filter options, machine components layout, etc. can only be relegated to the second line, so what is the current domestic use of the screw element? Let's make one, Analysis of the application, performance and occupancy rate of various domestic brands of screw element (excluding AC, IR, LU, FS).
1. Mainstream high-end. The main ones seen in China are AERZEN, GHH, TMC, and Rodcom.
AERZEN is genuinely imported from Germany (only sold by trading companies in China, but not produced in China).
GHH has been put into production in Jiangsu since 2009. At first, it mainly made some small oil-injected screws, within 10 cubic meters. Later, the foreign production lines were slowly moved to China. Therefore, GHH's oil-injected screws are mainly produced in Wujiang, Jiangsu (oil-free twin screw rotors can only be produced in Germany at present), the price is slightly higher than that of AERZEN, but it is the first to be promoted in China, and it is the standard application of domestic high-end air compressor brands. Among them, GHH is due to domestic production and Ingersoll Rand's technology and brand protection (GHH is a wholly-owned subsidiary of IR), the price/performance ratio is not as good as AERZEN.
TMC is an Italian company that mainly produces fans and screw heads. The ones seen in China are imported with original packaging. Some models are quite successful.
Rodekamp entered China relatively early, but due to the relatively short product line, it is mainly concentrated on the production of 3, 6 cubic monolithic heads (oil, oil filter, and air filter are concentrated on one main machine head), although the use situation is very good , But the market is shrinking due to cost-effective reasons.
2, mid-to-high end. The main engine of Hanbell and Nankou are selected by mid-to-high-end air compressor manufacturers. Among them, the main engines of Nankou are mainly 132 or above with better performance. As a company with Fusheng as its parent body (most employees are old Fusheng employees), Hanbell has taken a completely different path from Fusheng. Their technological updates, product control, and prices have completely overwhelmed Fusheng. At present, it is working closely with the leading domestic compressor company Red Five Rings, which has further improved both in sales and product technology.
3, low-to mid end . It is mainly produced by EU, etc., produced by Taiwan Fusheng, and adopted by Esens. Compared with Hanbell, although the EU screw element is also made by Taiwan compatriots, it is a standard version of Fusheng, and its performance is definitely not as good as that of Taiwanese compatriots. Fusheng screw air end.
4. Low-end mainstream. It is mainly based on Baosi, and currently the largest sales volume in the industry is the Baosi,host. Due to its stable performance and low price, Bose main engine is becoming more and more popular with low-end air compressor brands. The fatal disadvantage is low displacement, which is low efficiency. For example, Xinlei, Deslan, and Concor, most of them are According to the actual effect, the Bose main engine can reach 8 at most with 10 cubic meters, while the Han clock can reach 9.5.
5. Low-end air end. It is represented by Wuyang Saidwalker. Both the Wuyangside rotor and the casing are produced and assembled by itself, with the smallest diameter of the rotor. There are some other brands, I haven't heard of them very much, they should not be much better, so I won't introduce them.
