  1. Do not disassemble and assemble without

  The main material of prefabricated villas is light steel joist
  synthesized by hot galvanizing or aluminized galvanized steel strip cold rolling
  process. Through accurate calculation and supporting combination of auxiliary
  components, reasonable bearing capacity can be exerted to replace traditional
  houses. This kind of building has the same characteristics as all kinds of steel
  structures. All loads are pre-designed to ensure uniform loading of each
  component. In the process of design and installation, each part of the house is
  installed and fixed as a whole, and cannot be disassembled and assembled
  separately. Otherwise, the overall stability of the house will easily
  deteriorate and there will be relative potential safety hazards. If residents
  want to change the original structure of the house, they need to ask
  professional construction personnel to make changes. Before cons...    less

  How To Adjust Top Open Door Freezer In Summer

Reason: In summer, the ambient temperature is high, and at this time it is very difficult for the temperature in the top open door freezer to drop by 1 degree. Through the thermal insulation layer of the box body and the door seal, the temperature drop will also slow down, which often results in short startup time and long shutdown time.
  
  This will cause the press to run at high temperature for a long time, which will intensify the damage of the piston and cylinder, reduce the insulation performance of the motor coil enameled wire due to high temperature, and sharply reduce the power consumption, which is neither economical nor reasonable. If you change to weak gear at this time, you will find that the startup time is significantly...    less

  If you do n’t know much about the principles of elevators,
  let ’s take a look at some principles of elevator design with the China Elevator Lifts Factory :
  
  First, when the elevator overspeed reaches 115%, the speed
  limiter will act, cut off the control circuit, and the elevator brakes. If the
  brake fails, the speed limiter can then operate the safety gear through a
  mechanical device, thereby clamping the elevator on the guide rail.
  
  Since the first elevator in the world, designers have considered
  the protective measures when the wire rope breaks, and only elevators with such
  protective equipment (that is, the safety gear speed limiter device mentioned
  above) can be used for passengers. If all the facilities above fail, of course
  the probability of this happening is minimal. You pick up the back of the foot
  in the car, bend your knees, and bend down, so that the damage will be
  minimized. The elevator will be provided with buffe...    less

The force is the pressure when closing the mould, the pressure of the melt in the mould cavity and the pulling force when opening the mould, etc. The pressure of melt is the main factor. The dustbin mould generally works at a certain temperature and the temperature fluctuates.
  
  In addition, the dustbin mould will be rubbed by plastic and possibly corroded by corrosive gas when working. The working conditions of the dustbin mould are relatively harsh. To ensure the mould has a certain service life, the dustbin mould material, especially the moulding part material, must meet certain requirements.

  Drive Chain maintenance method
  
  1) The tightness of the stainless steel conveyor chain is
  important. Do not overtighten or loosen it, as this will damage the conveyor
  chain.
  2) The stainless steel conveyor chain should be kept clean to avoid
  sunlight and rain, and to prevent contact with acids and alkaline organic
  solvents.
  3) If the conveyor chain wears seriously, parts such as a new
  conveyor chain should be replaced to ensure good results and extend its
  life.
  4) Lubricating oil should be added in time when the chain is working,
  which can make the chain work more smoothly and quickly, and reduce wear and
  tear.
  5) The old conveyor chain cannot be mixed with the new conveyor chain.
  It should cause impact and damage the conveyor chain.
  6) Leave the conveyor
  chain there for a while, then use diesel oil or kerosene to clean it, then coat
  it with oil and place it in a dry place

  Glass Ball Manufacturer introduces the glass ball manufacturing process today.
  
  The first thing to know is that the raw material for making
  glass balls can only be glass. The glass is produced industrially. The raw
  materials are mainly quartz sand, feldspar, calcite, thenardite, etc. These 100
  ores must be heated to more than a thousand degrees to form a glass
  liquid.
  
  Secondly, qualified glass liquid flows through the feeding tank
  and flows out from the feeding port to form a material strand. The temperature
  of the stock is generally 1150 ~ 1170 ℃ for medium-alkali glass balls, and 1200
  ~ 1220 ℃ for non-alkali glass.
  
  Finally, the stock is cut into bulbs nearly 200 times per
  minute. The ball blank passes through the chute, the ball divider, and is pulled
  by the ball divider plate, rolls into different funnels respectively, and then
  falls into the ball forming groove formed by the three rollers with the same

Now let's take a look at the actual situation of the enclosed bus with ECCA wire and the structure of the branch cables. I think everyone is curious. Now let's get to know it.
  
  The main material for ECCA wire production, enclosed bus bar, is mainly formed by the conductor, shell and insulator materials of the carrier. The bus bar shell should be made of high-quality cold-rolled plates with sufficient mechanical strength. In order to prevent the grade from IP55, the current-carrying conductor is made of copper electrical materials of GB5585.1-5585.3, and the contact surfaces of conductor contacts are specially tr...    less
