Corrosion-resistant magnetic pump as the name suggests is a corrosion-resistant pump, mainly for the transport of corrosive liquids. Corrosion-resistant magnetic pump is a more common in recent years, a magnetic pump, which uses the world's best corrosion-resistant materials. But the instrument will be faulty, so we usually pay attention to maintenance, the following to share with you about the corrosion-resistant magnetic pump assembly and maintenance. (A) assembly sequence 1, the heating oil...
Solenoid valve procurement only clear the specifications, types, pressure to meet the procurement requirements of the practice in the current market economy environment is imperfect. Because the valve manufacturer in order to compete for the product, each in the valve under the concept of a unified design, different innovations, formed their own corporate standards and product personality. Therefore, when the valve procurement more detailed technical requirements, and manufacturers to obtain...
Valve body parts suitable for working temperature introduction 1 Overview Valve design and material selection must be one of the key issues to consider the working temperature of the valve. In order to regulate the appropriate working temperature of the valve body material, suitable working temperature and related to the valve body material for petrochemical, chemical, fertilizer, electric power and metallurgical industries in China from the material properties of various types of valve steel...
What are the functions of the pipeline valve? how to install? Common logo what does it mean? Failure, how to repair? Pipeline valve 4 kinds of functions First, cut off and release media This is the most basic valve function, usually the choice of flow-through valve, the flow resistance is small. Closed-down valve (globe valve, piston valve) because of its tortuous flow, flow resistance than other valves, it is less choice. In the case of allowing higher flow resistance, the choice of closed...
Pneumatic actuator repair tips Pneumatic actuator repair tips I. Overview Pneumatic actuators with oil-free compressed air as the driving force to actuate the valve or baffle action. There are the following types: pneumatic control valve, solenoid valve, pneumatic long stroke electric actuator. Second, pneumatic control valve Pneumatic valve by the pneumatic actuator and control valve of two parts. Pneumatic actuators with oil-free compressed air as the driving force, to accept the gas signal...
First, the causes of cavitation Cavitation is caused by the liquid vaporization, the liquid molecules escape the liquid surface, a process of gas molecules, known as "vaporization." The degree of vaporization of liquid pressure and the size of the high and low temperature. Dissolved in the liquid gas, pressure and temperature changes will be released, the formation of cavitation. When the internal pressure of the liquid drops below the saturated vapor pressure of the liquid at the temperature,...
When the purchase of visual valves, the surface should be no blisters; plating surface should be uniform, should pay attention to whether there is peeling, cracking, scorching, exposed, flaking, dark spots and obvious pitting and other defects; spraying surface tissue should be fine, smooth Uniform, no sagging, exposed defects. {TodayHot} Civil valves commonly used in ordinary households commonly used gate valve, ball valve, triangular valve and other forms, usually iron or copper. As the...
