China Bulldozer Steering Clutch Cylinder Manufacturer, Supplier, Factory

As a hydraulic equipment manufacturer, we often think about the installation order of relief valves and check valves when designing hydraulic systems. Both valves play an important role in hydraulic systems. The relief valve is mainly used to protect the system from damage caused by excessive pressure, while the check valve is used to prevent the reverse flow of oil.

Air in a hydraulic system can lead to decreased performance and even cause failures. Therefore, removing air from a hydraulic system is an essential step to ensure its normal operation. Here are several effective methods to remove air from a hydraulic system:

On May 20, 2025, Qingdao Micro Precision Machinery Co., Ltd. participated in the highly anticipated offline machinery seminar with its enthusiasm and spirit of exploration for the machinery industry. The seminar brought together many experts, scholars, enterprise representatives and technical backbones in the machinery industry, aiming to build a professional platform for exchanging ideas, sharing experiences and seeking common development, injecting new vitality into the continuous progress of the machinery industry.

As a manufacturer of hydraulic cylinders, we are well aware of the importance of excavator cylinders to equipment. Cylinders are like the "muscles" of an excavator, driving the excavator arm, bucket and other parts to complete various complex movements.

Hydraulic valve is an automatic element operated with pressure oil, which is controlled by the pressure oil of the pressure distribution valve, and is usually used in combination with the electromagnetic pressure distribution valve, which can be used to remotely control the on/off of the oil, gas and water pipeline system of the hydropower station.

In modern industry, hydraulic systems are widely used in engineering machinery, metallurgy and mining, petrochemical, port machinery and ships, and general machinery. A hydraulic system with excellent performance can run stably for ten years, while a system with design or manufacturing defects may become a continuous source of failure and maintenance nightmare. As the "muscle" of modern industry, the performance of the hydraulic system directly affects the life of the equipment and production efficiency. But what kind of hydraulic system can be considered high-quality? Many users often only focus on the price when purchasing, but ignore the key performance indicators.
