Hydraulic Solenoid valve is the control element of hydraulic systems, which use hydraulic solenoids as its power components. There are many different types of hydraulic solenoid valves, such as hydraulic directional valve, hydraulic proportional valves, hydraulic servo valves, etc.
Essentials for Hydraulic Systems
Hydraulic solenoid valve is a type of automatic element operated by pressure oil. It is controlled by the pressure oil of the distributing valves. Normally, hydraulic solenoid valve and distributing valve are used in combination to control the start and stop function of hydraulic systems. Hydraulic solenoid valves are divided into direct action solenoid valves and pilot solenoid valves, the pilot type solenoid valve is the frequently-used solenoid valve.
No matter which types of hydraulic systems you use, hydraulic solenoid valves are the essential elements. Hydraulic solenoid valve is used to control the flow directional and adjust the pressure and flow of hydraulic oils. In order to achieve the different functions, different hydraulic solenoid valve adopts different hydraulic solenoid as the power actuators. Typically, according to its different functions, hydraulic solenoid valves can be divided into directional valves, pressure valves, flow valves.
Hydraulic solenoid valves are the most widely used hydraulic products. Except for the different functions, there are also many different ways to classify the hydraulic solenoid valves, such as the different control methods, different valve structures, etc. The different solenoid valve features provide large numbers of combinations, therefore, hydraulic solenoid valves also maintain the maximum products types. With the numerous hydraulic solenoid valve types, it is one of the basic components of hydraulic systems.
Common Equipment Use Hydraulic Systems
Hydraulic solenoid valves have been applied in all the hydraulic systems, but what is hydraulic system? Is it a common system we have seen every day, or it is just a special equipment for some niche markets?
From the above contents, we may feel that hydraulic solenoid valves are too messy, there are so many different solenoid valve types, and we have absolutely no idea what hydraulic systems are. Actually, hydraulic system has a very large application, everyone has seen or used the equipment which adopts hydraulic systems, such as water pump, excavator, bus, etc. In the following contents, we will give you a general idea about hydraulic systems, and shows you some common equipment that uses hydraulic systems.
The working method of hydraulic systems is based on hydraulic transmission. Hydraulic transmission is using fluid as the working media to pass energy and control the working of equipment. With the development of hydraulic transmission technology, hydraulic system becomes an industrial essential. Based on industrial actual usage, hydraulic system uses hydraulic oil as its working media, it is an important fundamental element in the industries such as vehicles, airplanes, aerospace, tubing, etc.
Except for the transportation industries, there are also many different important materials are formed by hydraulic equipment, such as carbon steel, stainless steel, aluminum alloy, copper alloy, nickel alloy, etc. Which means, the cold forming materials used for electrical appliance factories, gear factories, heat treatment plants, electronic equipment factories and all kinds of machine parts are formed by hydraulic equipment.
Not only the materials forming industry, hydraulic equipment also has a wide application in the machinery industry. No matter it is for civil industry or national defense industry, no matter it is for general precision control or high precision control, the utility ratio of hydraulic equipment is over 50 percent. Take the different machinery industries as an example:
- Engineering Machinery: excavator, wheeled loader, automobile starter, crawler dozer, motor scraper, bulldozer and road roller are using hydraulic systems.
- Agricultural Machinery: hydraulic systems are widely used in all types of harvesters, tractor, and hydraulic suspension system.
- Automobile Industry: there are some parts of cars that are hydraulic systems. For example, hydraulic brake system, hydraulic dump mechanism, and the aerial ladders are hydraulic systems.
- Metallurgical Industry: hydraulic systems have been widely used in the control system of metallurgical machinery, such as the control system of electric furnace, the control system of rolling mill, the control system of converter furnace and the control system of blast furnace.
- Textile And Light Industry: hydraulic systems has been used in molding plastics machines, rubber vulcanizing machines, paper machines, printing machines, textile machines, and so on.
- Shipping Industry: hydraulic system has been used in hydraulic dredger, salvage ships, production platforms, aerofoil boats, air cushion vehicles, and the marine auxiliary.
As we can see, hydraulic equipment has such a wide application range, which makes it significantly important for us. As the developed needs of hydraulic equipment, the demand for hydraulic solenoid valves will also grow heavily in hydraulic equipment manufacture industry.
