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:How do you clean the inside of the electric oven? Can you use a wire ball or a detergent?
Remember a TV show that USES a bowl of lemon water cloth cover, ten minutes of evaporation and then a soft cloth to wipe it off without a chemical smell.
Q:What are the types of cleaning equipment
There are many kinds of cleaning equipment, mainly automatic washing machines, sweeping machines, vacuum cleaners, and high pressure cleaning machines. And some are less common, such as: stone crystal machine, carpet cleaner, sofa cleaning equipment according to the clean area of different models and choose to use the equipment and is not the same.
Q:Is there any molding equipment in the car engine?
The car engine is cleaned with molding equipment. Automobile engine cleaning equipment is mainly used for cleaning the various parts of the car parts such as turbocharger, shock absorber parts, aluminum, iron, copper die casting, ductile iron parts, cylinder block, shell, piston rings, hydraulic parts, compressor spare parts, and so on mechanical hardware parts, cleaning production and processing process or terminal. Such as the typical gj-6000, which is used to clean the grease and dirt of foreign metal parts such as auto supercharger parts. The advantages of rapid cleaning and drying are applicable to batch production.
Q:The heavy oil on the machine should use what cleaning agent to clean up?
Weigh? There is a kitchen called wei-bang kitchen, which is good, I don't know
Q:What are the methods of general cleaning of mechanical equipment?
Oil seal rupture Water, oil, special cleaning agent.. et.
Q:What is suitable for factory cleaning equipment
Industrial vacuum cleaner is used to collect waste gas, dust and debris from equipment in industrial production, purify workshop environment, and no secondary pollution. High pressure cleaning machine, clean equipment oil pollution, rust stain, and some areas with small and unsanitary areas.
Q:How do you clean the household central air conditioner
You're the one that's in the middle of a draught tube, usually cleaned by a professional and included in the installation cost
Q:Procter &gamble has some common cleaning equipment in the cleaning of the property

Q:How often do the reverse osmosis of pure water equipment wash the search?
Generally, under the condition of normal operation, reverse osmosis membrane may also be inorganic scale, colloid, microorganism, metal oxides, such as pollution, these substances deposited on the membrane surface to cause water purification equipment, reverse osmosis device output descent or desalination rate, differential pressure increases, and even cause unrecoverable damage to membrane, therefore, in order to restore good waterproof and desalination performance, need for chemical cleaning membrane.
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.
