Shanghai Huawei Technology Co., Ltd
Shanghai Huawei Technologies Co., Ltd. was established by Huawei Technologies Co., Ltd. in the Free Trade Zone Market Supervision Administration on January 16, 2001.
As the world's leading provider of information and communication technology (ICT) solutions, Huawei focuses on the ICT field and provides competitive products and services for operator customers, corporate customers and consumers. It has won the "2019 China Brand Power Festival Annual Glory" brand".
On October 29, 2021, Huawei released its operating results for the first three quarters of 2021. In the first three quarters, the company achieved sales revenue of RMB 455.8 billion and a net profit margin of 10.2%.
The main components of the equipment:
The equipment purchased this time is a hydrostatic bearing series hydraulic actuator hydraulic system, which is mainly composed of hydrostatic bearing actuators (including servo valves, displacement sensors, load sensors, etc.), control systems, cooling towers, hydraulic station pipelines, etc. .
The hydrostatic bearing actuator mainly has the following characteristics:
1. The hydrostatic bearing is equipped with a hydrostatic piston rod guide, and the rod guide and the seal are in one component. The piston rod floats on a layer of oil film and can withstand large transverse shear forces. The pressure supply of the hydrostatic bearing is realized through the internal structure of the cylinder, which can withstand large lateral forces. Because the contact seal and the dust ring do not bear pressure, the residual friction force in the entire pressure range is very small, so Ensure the high dynamics and long life characteristics of the servo hydraulic cylinder.
2. The annular gap seal is a non-contact seal. Due to the pressure difference, the oil passes through the smaller orifice to form a very thin oil film, thereby replacing ordinary seals to achieve the sealing effect, but all The maximum lateral force to withstand is limited. Since the contacting seal and the dust ring do not bear pressure, the piston rod is guided by a guide element optimized for friction, so the starting friction is very small in the entire pressure range, thus ensuring the high dynamics of the servo hydraulic cylinder And long life characteristics;
3. The hydraulic buffer is set at the stroke limit position of the servo linear actuator to avoid damage caused by running out of control.
