According to the current market demand survey, it is not difficult to see that the pneumatic butterfly valve pedestal is mainly used for water pumps. There are also other equipment, such as fans and air conditioners, but they are in a minority. According to the market feedback, 90% of the customers chose to install the damping pedestal when installing the pump, which shows that the market recognition of the pneumatic butterfly valve pedestal is relatively high.
Since the shock absorber pedestal is to be installed, there is a problem of model selection. Whether the model selection is correct or not will affect the following problems:
1. Can it be installed successfully?
2. Can the valve efficiency of the water pump meet the standard requirements?
3. Is it beautiful and practical?
Therefore, the selection of pneumatic butterfly valve pedestal is very important, and the key points of selection are summarized as follows:
1. Type selection of water pump pedestal
Damping pedestal is generally divided into two types: side support type and built-in type. The selection of the two is based on the site environment, without special requirements. Generally, the embedded valve pedestal is selected, which is lower in cost than the side support type damping pedestal. If there is height limitation on the site, the side support type damping pedestal is generally selected to solve the height limitation problem. However, no matter which type of pedestal is selected, there is little difference in terms of valve efficiency and other technologies.
2. Maximum size of valve seat
If you choose an embedded valve pedestal, the size of the pedestal can be less than or equal to the size of the equipment foundation. If it is a side supported vibration damping pedestal, the pedestal size includes the pedestal and side feet, and the overall size is less than or equal to the size of the equipment foundation.
3. Conventional dimensions of the pump shock mount
The size of the pump damping pedestal should be larger than the size of the pump base, and the size increase on each side should be 150 mm;
4. Weight ratio of damping pedestal (inertia fast) to water pump
With regard to the weight of the pump damping pedestal, the specification and the consultant's technical specification clearly stipulate that:
CECS5984 Technical Specification for Vibration Isolation of Water Pump stipulates that the weight of inert and fast water pump shall not be less than the total weight of water pump unit, generally 1.0~1.5 times of the total weight of water pump unit;
Pump installation standard 16K702: the weight of concrete vibration isolation pedestal shall not be less than 2 times of the equipment weight;
