Trap installation precautions

Trap installation precautions
The core prompts: (1) When it is installed in a rising position In general, traps are installed at positions below the condensate discharge device. However, if you want to install the trap higher than cold
(1) When it is installed in a rising position
In general, traps are installed below the condensate drain device. However, if you want to install the trap higher than the condensate drain device, install the poppet in front of the trap so that the condensate can flow into the trap smoothly. Liftfitting: Also known as "lifting joint". When the condensate drain site is low, it can suck the condensate to a high point and guide it forward.
(2) Exit side recovery pipe
The diameter of the piping used to recover the condensate discharged from the trap should have a certain margin, at least to prevent the influence of steam hammer or pressure loss. In addition, when connecting the recovery pipe to a plurality of collector pipes (back pipes), a certain inflow angle should be created to facilitate the flow of the condensed water.
(3) When the outlet piping is flooded
When the condensate drains to the drain, if the drain pipe is directly extended into the water, the danger of condensate splashing may be caused. If it is necessary to be flooded, in order to prevent the water in the drain from flowing back to the trap when the steam is stopped, it is necessary to make a hole in the drain pipe or install a vacuum adjustment valve.
(4) Setting of the condensate collecting device
When a trap is installed in the steam conveying pipe, it is necessary to design a condensate collecting device.
In the early stage of ventilation and the fast flow rate, it can effectively collect condensate, which will help the trap to work better. If the condensate collecting device is not designed, it is easy to see that the condensed water is not discharged and garbage. Scale blocking entrance and so on.
(5) Recovery of condensate lines with different pressures
For condensate lines with different pressure conditions, the condensate recovery pipes must be designed for each different pressure, or flashlegs must be installed for recovery. Once the high-pressure condensate flows into the low-pressure recovery pipe, the condensate will evaporate again due to the temperature difference of the condensate, thereby generating noise. Steam hammer and other adverse effects.

Product introduction
Steel Bending Machine, one of steel reinforcement processing machinery.
The working mechanism is a horizontal working disk rotating on the vertical axis. The steel bar is placed in the dotted line position in the diagram. The supporting shaft is fixed on the machine tool.

For bending steel bars of various diameters, there are several holes on the work plate to insert the bending pin shaft, and the center pin shaft of different diameters can be replaced accordingly.

Advantages of characteristics
Applicable to all kinds of round steel, carbon steel, screw steel.
It has strong operability, high working efficiency, convenient Angle adjustment and neat bending
Operation procedures of steel bending machine:

1. Check whether the mechanical performance is good, keep the working table and bending machine surface level;
And prepare various spindle tool blocks.

2. According to the requirements of the diameter of steel bar and bending machine, the core shaft, forming shaft, iron shaft or variable structure shall be installed. The core shaft diameter shall be 2.5 times of the diameter of steel bar.

Check the core shaft, block and turntable shall be free of damage and crack, and the protective cover shall be tightly fixed and reliable, and the operation shall not be performed until it is confirmed that the air machine is running normally.

Iv. During the operation, insert the bend end of the steel bar into the clearance provided by the turntable for fixation, and fix the other end close to the fuselage and press it with your hand to check the fuselage fixation.

The side that actually holds the steel bar can be moved.

It is strictly forbidden to change the spindle, change the Angle, adjust the speed and so on.

When bending steel reinforcement, it is strictly forbidden to process steel reinforcement diameter, root number and mechanical speed beyond the mechanical specification.

When bending high hardness or low alloy steel bars, the maximum limit diameter shall be changed according to the mechanical nameplate, and the corresponding mandrel shall be replaced.

8. It is strictly forbidden to stand in the working radius of the bending steel bar and the unfixed side of the fuselage.
Curved semi - finished products should be stacked neatly, curved hooks should not face up.

When the turntable is turned, it must be done after it has stopped.

X. completion of operation, cleaning of site, maintenance of machinery, power off lock box.
