The stability of the engine and transmission assembly damping pad is also an important factor in selecting the damping pad planning scheme. In order to ensure that the damping pad has sufficient static load to meet the requirements of the power transmission system of the loader for its service life, the additional static load capacity must be ensured when selecting the appropriate stiffness of the damping pad. The electric butterfly valve of butterfly valve is used more and more widely, and there are more and more derivative products.
In particular, industrial butterfly valves and electric butterfly valves, such as stretched spring electric butterfly valves, electric butterfly valves, and fan electric butterfly valves, are gradually becoming prominent in all walks of life, and are beginning to play a decisive role. The reason why the electric butterfly valve of butterfly valve can be continuously developed in the footsteps of the times is that its strong development foundation and outstanding renewal potential Select the appropriate lifting electric butterfly valve, including the appropriate type of lifting electric butterfly valve and the correct installation load.
Fix the indicator plate of the hanger on the position corresponding to the installation load with the upper and lower positioning blocks, so that the butterfly valve hanger is in a rigid state and exists stably. 2. Hoisting equipment and hoisting equipment shall be confirmed carefully and there is no uncertain risk factor to ensure the safety of hoisting. 3. After the overall installation, the equipment starts to run. First check whether the positioning block exists, and then check whether the indicator board is jammed during the displacement from the installation load to the working load.
Whether there is a large displacement. 4. After entering into normal operation, check whether the displacement of butterfly valve support under working load is consistent with the design. After the equipment stops running, check whether the indicator board returns to the position where the load is installed. Correct installation data can be obtained by testing the above precautions to ensure stable shock proof effect and safety of the valve. The purpose of using electric butterfly valve varies according to different situations.
For example, sometimes it is to reduce the vibration stress to extend the working life of the equipment; Sometimes it is to reduce the amplitude of vibration so as not to affect other equipment due to vibration; Sometimes it is to extend the vibration period and make people comfortable (such as cars). For the shock caused by sudden impact, the amplitude of the shock attenuates much faster after the use of electric butterfly valve than when there is no electric butterfly valve. After using electric butterfly valve for continuous seismic source, the amplitude is generally reduced.
There are various types of electric butterfly valves, which can be divided into fixed type (such as electric butterfly valve on the base) and rotary type (such as electric butterfly valve on the rotor and electric butterfly valve on the bearing) according to whether the electric butterfly valve is rotating; According to the valve principle of electric butterfly valve, it can be divided into elastic electric butterfly valve, friction electric butterfly valve, impact electric butterfly valve, electromagnetic electric butterfly valve, hydraulic electric butterfly valve, balance electric butterfly valve, etc; It is classified according to the valve materials used for electric butterfly valves. It can be divided into electric butterfly valve, butterfly valve electric butterfly valve, air electric butterfly valve, oil electric butterfly valve, etc. For the electric butterfly valve of XHS hanging butterfly valve and the electric butterfly valve of fertilizer machinery.
