A vacuum pump is a common and commonly used type of pump among many pump products. It is a device that improves, generates, and maintains a vacuum in a confined space by mechanical, physical, chemical or physicochemical methods , In metallurgy, chemical industry, food, electronic coating and other industries have a wide range of applications, then it and ordinary pump What is the difference between? The most important feature of the vacuum pump is that it can form a vacuum, which can be seen from its name, which can not be achieved by ordinary pumps. This is the most important difference between the two. Vacuum pump is by a rotating wheel, rotating in the chamber, the chamber filled with fluid, the remaining cavity volume cyclical changes in the volume of the fluid under the action of periodic changes on the suction pipe gas Exhaled and inhaled. The most common vacuum pumps are dry screw vacuum pumps, water ring pumps, reciprocating pumps, slide valve pumps, rotary vane pumps, Roots pumps and diffusion pumps. The following is to say ordinary pump. Centrifugal force, the centrifugal pump will be thrown out of the fluid at the same time the formation of negative pressure, and then the other fluid in its suction will continue to enter the pump body, pump impeller into the kinetic energy and potential energy driven by consumption of motor Electricity to complete.

How to clean led aluminum lamp cup, what kind of cleaning agent should be used in led aluminum lamp cup? LED aluminum lamp cups are more or less contaminated with some processing oil or other dirt during the processing. What method can be used to remove such dirt as quickly and as simple as possible? From the perspective of cost, the ultrasonic cleaning method is generally only a single-tank cleaning. The simple process is: ultrasonic cleaning - rinsing - rinsing - drying. The cleaning agent uses a water-based cleaning agent, and considering the active nature of the aluminum, it should be a neutral water-based cleaning agent. There are already targeted products on the market, such as the special cleaning agent for CLF LED aluminum lamp cups of Evergreen Chemical Company. The cleaning agent mainly uses the active material as the main component, and the various substances on the surface of the aluminum lamp cup are dissolved into the water by the penetration and emulsification of the active material on the oil stain.

Cast steel gate valve : It is all gate valves that are cast into castings made of metal steel materials, collectively called cast steel gate valves. And also cast iron gate valve corresponding, forged steel gate valve malleable iron. The following matters should be noted in the installation and maintenance of cast steel gate valves: Handwheels, handles and transmission mechanisms are not allowed to be used for lifting, and collision is strictly prohibited. The double gate gate valve should be installed vertically (ie the stem is in the vertical position and the handwheel is on the top). The gate valve with the bypass valve should open the bypass valve before opening (to balance the differential pressure between the inlet and outlet and reduce the opening force). The gate valve with transmission mechanism is installed according to the product manual. If the valve is used frequently, it should be lubricated at least once a month.

Valve castings have been in a stage of rapid development in China. They are one of the largest valve casting machining centers in Asia and one of the largest valve castings markets in the world. They have their own place in the international market. In recent years, China's economic development stage has been rapid. China's valve casting industry has played an important role in preparing the manufacturing industry as an important link in the development of the national economy. It plays an important role in the important areas related to national economy and people's livelihood, such as millions of kilowatts of nuclear power and large-scale cleaning. High-efficiency power generation, supercritical thermal power, gas-fired steam cycle, large-scale hydropower and pumped storage, large-scale air-cooled power stations and other units and large circulating fluidized bed boilers, etc.; million tons of large-scale ethylene plants, paraxylene, phthalic acid, poly Fat equipment; large-scale coal chemical equipment; large-scale underground mining, lifting and washing equipment; large-scale ships, large chemical vessels, aircraft carriers, CNG; atmospheric governance, urban industrial wastewater treatment, urban pipe network transformation, etc. For the matching of valves, it is necessary to meet the requirements of the national economy industry for valve manufacturing, to achieve scientific development of the entire industry, to take the lead in development, to achieve good and fast development, to seize domestic and foreign market opportunities, forge ahead, and strive to build China into a global valve casting. The main production base of the industry. After years of development, the number of valve casting companies in China ranks first in the world. There are about 6,000 valve companies of various size

In recent years, China's pump valve casting industry has developed rapidly, but there are still a lot of problems. Due to the long-term price war in the domestic pump and valve industry, the pump and valve industry has been stuck in the middle and low position of the world's valve industry for a long time. Therefore, our country's valve and valve industry must start from changing the competition mode and change the weak status of China's pump and valve industry. China's valve casting industry has developed rapidly, but its overall level is still low, its product technology content is low, and key valves also rely on imports. China's existing valve level is at least 10 to 20 years behind that of the internationally advanced countries. There are still many defects in quality management in China. First of all, the process is more or less neglected. Many companies clearly have a quality assurance system, but they have no place in practical work. Quality management is performed by itself, arbitrary; secondly in the assembly process. It is also sloppy. It is no wonder that some valves have appeared running, running, dripping or leaking as soon as they are installed. Another example is the backwardness of many domestic enterprises' production equipment, which has remained at the level of the 70s to 80s of the last century. Some equipment has already passed the service life and is still running at full capacity. How can the quality of product processing be guaranteed? With limited funds, CNC and machining centers have also been added one after another. However, the number of companies that form CNC machining has not been large in the industry so far, accounting for only about 20%.

The common quick coupling is a spare part product for connecting pipes. There are many different types of quick connectors on the market. They can be classified according to size specifications, and the corresponding models and names are also different. We should have a specific understanding of the different quick couplings, and we should also refer to the specifications between the pipe and the interface for proper matching. Next, let's take a look at what are the specifications of the quick connector! Quick connector specifications In general, the difference in the specifications of the quick connector of the water pipe generally refers to the difference of its interface. The interface specifications generally exist in 1/2, 3/4 (4 points, 6 points). When you buy, you must pay attention to whether the interface can match the water pipe or water gun interface that you need to install the connector, so as not to cause inconsistencies, you need to exchange or return the trouble. Others use stainless steel quick connectors. A type quick connector is a simple description: A type quick connector is a male head, it has no lugs on both sides, and the connection of one end is directly locked with the female head with lugs. One end is internally threaded. Brief description of B-type quick connector: B-type quick connector has a pull ear at each end, which belongs to the female head. One end of it is directly connected to the male head, and the other end

In order to improve the machining accuracy and working efficiency of CNC machine tools, the temperature of the CNC machine oil tank must be controlled within a certain range. On the one hand, the change of oil temperature directly affects the change of the temperature field of CNC machine tools, and the change of temperature field affects the change of displacement field. The displacement field changes inevitably affect the machining accuracy. On the other hand, the temperature changes, affecting the viscosity of the oil. Normally, the temperature rises and the viscosity of the oil drops. The viscosity is too high, the resistance is too large, which is unfavorable for starting and working of the hydraulic pump; if the viscosity is too low, it is easy to cause oil leakage and affect the stability of the entire hydraulic system. In addition, if the temperature is too high, it will affect the life of the hydraulic components and change the characteristics of the hydraulic oil itself. Introduction to the principle of fuzzy control of the fuel tank temperature. Anything is ambiguous in itself. It can even be defined as a different value, so the resulting set of theories, called paste mathematics. An important branch of fuzzy mathematics is fuzzy control. When dealing with complex problems, the fuzzy theory is closer to the objective existence rule. Especially for the time-varying and large-delay controlled objects, the fuzzy control is more accurate than the traditional control. Fuzzy control is based on artificial experience and does not require an accurate mathematical model for the controlled object. For the temperature control of the hydraulic fluid tank of CNC machine tools, the operator can easily observe the difference between the actual output temperature and the set temperature, and the change of the temperature difference. Therefore, design a two-input single-output fuzzy controller to realize fuzzy control. The fuzzy controller is composed of fuzzy, fuzz
