Introduction
Hydraulic roof support is the key equipment in the longwall mining method,which are used to support the tunnel roof of the mining face to make a space for armored face conveyors and shearers to operate underneath.The development of filling hydraulic support can prevent the ground subsidence, to fully realize the coal mining under buildings, railways and waterbodies, to prolong the service life and save resource.
Meaning of model
- Q: What are the benefits of sanitation
- The protection equipment and make it is not too bad
- Q: Procter &gamble has some common cleaning equipment in the cleaning of the property
- High pressure rinsing machine: for exterior wall, car and other special cleaning equipment that needs high-pressure water. When activated, it can produce a strong shock flow to remove dust, mud and other dirt.
- Q: What is the cleaning equipment?
- The use of clean devices must be used by everyone. This calls for clean devices to be developed in a simplistic direction, lowering the barriers to entry and allowing clean devices to be used like "dumb" cameras. The development of clean equipment also requires manufacturers to make products that are easier for people to use, in order to maximize the needs of different users. To create convenience for users is to create wealth for ourselves.
- Q: Characteristics of cleaning equipment of cleaning equipment
- The cleaning time can be adjusted arbitrarily, suitable for different places. The casing is made of stainless steel, beautiful and generous. Improve the cleaning effect. Adopting high-quality imported parts, ultrasonic power conversion rate is high, the power is strong, the cleaning effect is good. Main application: auto parts, optical lenses, metal stamping parts, electronic industry, aviation industry, mechanical hardware, medical apparatus and so on.
- Q: What is suitable for factory cleaning equipment
- Automatic sweeping machine, used to clean the ground garbage, dust, debris and so on, is artificial clean more than eight times.
- Q: How often do the reverse osmosis of pure water equipment wash the search?
- Generally 3 ~ 12 months clean, if every month had to be cleaned once, this explanation should improve the pretreatment system, adjust the running parameter. If you need to clean it once or three months, you will need to improve the operating level of the equipment, and it is difficult to determine if you need to improve the pretreatment system.
- Q: The oil can be cleaned by the tank cleaning and the cleaning of the tank is the cleaning of the machine
- There are a lot of mechanical cleaning equipment in storage tanks, and the cleaning process is different, and the cleaning effect is different.
- Q: What are the methods of general cleaning of mechanical equipment?
- It is commonly used for dry cleaning and washing 1, dry cleaning: it is with a bit like a sponge absorbing water materials, such as spray (drop) some detergent or anything on the brush, complete with relatively wet objects in to wipe again, finally just now with the dry items all dry clean place (general comparison precision of the equipment) 2, rinse directly with water, direct and clear, and then dry (directly dry, the equipment is large). This kind of equipment is not afraid of water Most of it comes in the first way
- Q: Clean the cleaning parameters of the equipment
- Judge a ultrasonic cleaning machine general technical indicators as to stay ageing degree and resonant, impedance and impedance matching are already debugged before they go out, the key lies in you to do. Of course, the sound of ultrasonic cleaning machine and generator is now being silenced. The bonding mode of the oscillator is usually made of special cement, and the bolt fastening effect is good, but it is not suitable for maintenance. Frequency selection is cleaned according to the workpiece to decide, general material or on the surface is not very high, with 28 KHZ, more strict for cleaning, or had better choose high precision parts. This is because, the lower the frequency of the bubbles, the greater the when ultrasonic frequency is greater than 800 KHZ, there is no cavitation bubbles, this to be the effect of cleaning the surface of the cavitation corrosion is the lowest. In addition, the ultrasonic cleaning is the effect of the high pressure produced by an empty bubble in the instantaneous blast.
- Q: Is there any molding equipment in the car engine?
- We now have the patent equipment hydrogen carbon removal machine, especially the combustion chamber carbon cleaning cars, clean up three yuan may oxygen sensor at the same time, only for 15 minutes, without having to remove the parts, don't need an oil change
