In response to the new fuel consumption standard to be implemented in China in 2015, all auto companies have formulated power upgrade plans. In the field of passenger cars, and even in the field of micro passenger, a hot trend of automobile engine upgrade has been set off. Wuling, chang 'an, dongfeng xiaokang, haima zhengzhou and a large number of minicar enterprises have invested a lot of manpower and financial resources in engine research and development and manufacturing, marking that the Chinese minicar market has gradually entered the "core" era.
Take haima zhengzhou as an example. As early as April 2009, haima group proposed the "blue engine" strategy for new energy and powertrain, and made detailed plans for the future independent power development of haima group. In 2011, the first phase of haima zhengzhou engine factory was completed and put into operation, with a planned capacity of 300,000 units. By the end of the 12th five-year plan, haima zhengzhou engine factory will have a total annual production and sales of over 1 million engines and become the world's leading engine research and development manufacturing base.
Core parts for free replacement policy. "This seemingly harsh condition is actually derived from haima zhengzhou to hai. In addition, haima m-series engine is the first company in the field of minicar to implement a three-year warranty policy of 100,000 kilometers and a free replacement policy for eight core components of the engine. These seemingly harsh conditions are actually derived from haima zhengzhou's confidence in the series of engines. At the same time, the seahorse M series engine has also passed 10,000 hours of platform endurance, resonance endurance, cold and heat shock, vehicle endurance, and more than 1 million kilometers of vehicle adaptability road test, 24-hour limit test and other harsh tests, and won the "2011 small displacement engine" award.
Hydraulic power unit should be used oil viscosity for the 43 mm/s (50 ℃) 27 anti-wear hydraulic oil, the oil temperature is lower than 50 ℃ is recommended when YA - N46, oil temperature is above 50 ℃ is recommended when YA - N68, join the oil should be filtered to 30 um filter precision, 80% of the fuel tank volume for the amount of regular, conventional oil temperature should be within the scope of the - 10 ~ 80 ℃, cold area in particular, should use the hydraulic oil at low temperature, such as YA - N32 by mechanical blending.
Hydraulic power unit of the hydraulic pump high work pressure refers to the working pressure of hydraulic pump and the load increases, when the work pressure to increase the strength of the hydraulic pump parts itself value and allow larger leakage, hydraulic pump's working pressure is no longer increases, when the hydraulic pump pressure to a higher working pressure.
The rated pressure of the hydraulic pump is the higher working pressure that the hydraulic pump is allowed to achieve in the work, that is, the pressure marked on the nameplate of the hydraulic pump or the product sample.
