How To Select Model

  • What are the types of pneumatic hammer and pneumatic vibrator, how to select them, and what key points should be paid attention to when selecting models?
    1. Pneumatic vibrators are available in a variety of different types of vibrators, such as single-hit type, reciprocating type, rotating type and so on.
    2. Common considerations: air consumption, noise, installation space, frequency, vibration, etc.
    3. Selection Step:
    4. ·Select all possible vibrators according to the required force.

      ·Select silencers if a quiet workplace is required.

      ·Select single-hit pneumatic hammer if small air consumption is required.

      ·The most suitable type of vibrator is selected according to the wall thickness and material of the hopper, the blanking angle and the fluidity of the material.

    5. On the premise of equal performance, a small vibrator is used on both sides to replace a single large vibrator to prevent excessive force on a single point.
Installation

Installation and Operation

  1. What are the precautions for the installation of the liquid level switch?
  2. Can multi-point float level switch measure both liquid level and temperature?
  3. What are the precautions for the installation of the level switch?
  4. Why can’t the ultrasonic level sensor be installed in the middle of the vault tank?

The stability of the float of the level controller is easy to be affected by external sundries, especially the entangled fibrous sundries that lead to mistake, therefore, it is not appropriate to use more than one float in the same small water tank, otherwise it will be entangled. The service life is relatively short, and most of the direct connection is 220V, thus there is potential security risk and the electric leakage may cause electrocution someday due to the damage of the electric wire. Therefore, the power cord of the float switch is an integral part of the device. Once the wire is found to be damaged, the device shall be replaced and the wire shall not be repaired.

The multi-point float level switch is one kind of safe and reliable level controller with easy operation and simple structure. One product can achieve multi-point control. It is characterized by long service life and fast speed with strong resistance to load shock.

The multi-point float level switch is operated by magnetic force without mechanical connection parts, and the operation is simple and reliable. When the float switch is floated by the measured medium, the float drives the main body to move, and the magnet at the other end of the float controls the magnet on the switch lever.

One or more magnetic reed switches are fixed to a closed metal or plastic tube. When the inner hollow float with fixed permanent ring magnet approaches or leaves the switch along the tube, the float floats up and down. The magnet inside the float is used to attract the contact of the magnetic reed switch to generate the signal ON and OFF.

The level switch is widely applied in modern industrial production processes and storage departments. It can monitor and control the upper and lower limits of the powder level and granular materials in the container. Due to the wide variety of level switch products, the installation method of the level switch is not the same, and the installation precautions are slightly different. So, what should be paid attention to when installing the level switch? In general, the following should be noted for most of the level switches:

1. Before installation, it is necessary to confirm that the level switch model meets the condition requirements of the site, such as process pressure, process temperature, and chemical properties of the medium, to ensure that the level switch can be used normally after installation.

2. Before installation, make sure that the power supply voltage is consistent with the voltage on the label.

3. In order to ensure personal safety and avoid damage to the level switch, it should be connected when power is cut off.

4. Keep away from the material inlet when installing.

1. Do not install under the water inlet to avoid malfunction caused by liquid impact.

2. When installed in a tank with stirring or fluctuating, the protection tube or level switch with delay setting function should be installed.

3. Anti-corrosive level switch is required for the detection of acid and alkali liquids.

4. Keep the connection box inlet downward, and the cable outlet fixed nut must be locked to prevent the penetration of liquid into the connection box.

5. Other notice should be paid attention to:

The specific gravity of the float is less than that of the liquid;

The diameter of the opening for installation is larger than the diameter of the float;

The installation position should not be close to the water inlet and outlet.
