AboutWuhan New World Refrigeration Industry Co., Ltd. (hereinafter referred to as "Wu Leng"), formerly known as Wuhan refrigerator factory, was established in 1954 and has a history of nearly 70 years. It was originally one of the large backbone enterprises under the Ministry of machinery industry, and is now one of the core enterprises of Dalian Bingshan Group.
-
ProductsScrew refrigeration compressor, a traditional refrigeration product of Wuleng, has the characteristics of small size, high efficiency, low energy consumption, few wearing parts, high stability and long service life. Since the successful development of the first screw machine in 1978, Wuleng has produced more than 60000 screw machines (sets) and is one of the large backbone enterprises in China's air conditioning and refrigeration industry.
-
NewsWith precision machining, compressor assembly, pressure vessel production, unit assembly, cold storage equipment production and other modern assembly lines and 4 sets of product performance testing platform, with an annual output of more than 3000 sets of screw products (sets) capacity.
-
CasesThe screw machine produced by Wuleng is widely used in petroleum, chemical industry, air conditioning, refrigeration, hydropower, textile, coal, pharmaceutical, food, beer, sports venues, exhibition centers, marine refrigeration, national defense science and technology and other fields. It has also entered the international markets of Africa, Oceania, South America and Southeast Asia.

MessageDetails Introduction
Screw compressor for the open type twin screw design, from the mid-1970s has been developed to the screw III machine, screw III machine has experienced 15 years of market test, through continuous optimization and improvement, the theoretical displacement specifications more complete, reliable and efficient operation.
The fourth generation WL-C rotor type line, the comprehensive efficiency is 2 ~ 3% higher than other type line.
Brand rolling bearing, rated life up to 40000h. To maintain accurate positioning, the rotor clearance is small, and the cooling capacity of the compressor using rolling bearings is 2 to 3% higher than that of the sliding bearing compressor under the same working conditions.
High-quality mechanical seal, sealing pressure up to 2.5MPa, to prevent leakage, long service life.
Differential pressure oil supply, a small oil pump is only used before starting, saving oil pump power consumption.
The energy and internal volume ratio are automatically adjustable to ensure that the compressor runs more economically under various working conditions.
The suction filter is built into the body to make the unit more compact and more beautiful in appearance.
Suction and exhaust stop valve and check valve into one, effectively reduce the volume of the unit, reduce the flow resistance, while reducing the leakage point.
Evaporation temperature:-45 ℃ ~ 5 ℃ (please contact our company if the evaporation temperature exceeds 5 ℃); Condensation temperature: ≤ 45 ℃;
Exhaust temperature: ≤ 105 ℃; oil temperature: ≤ 65 ℃;
Cooling water inlet temperature: 20~32 ℃
