National treasure explosion-proof sewage pump type record
1. The flow rate used in the working condition is one of the important performance data of the self-priming sewage pump, which is directly related to the production capacity and transportation capacity of the entire device. When selecting self-priming sewage pump, based on large flow, taking into account normal flow, when there is no large flow, it is usually advisable to 1.1 times the normal flow as a large flow.
2. The flow head met on site makes the type and performance of the selected explosion-proof pump meet the requirements of the device flow, head, pressure, temperature, cavitation flow, suction and other process parameters. The head required by the device system is another important performance data of the selected pump, which is generally selected by magnifying 5-10 percent of the residual head. Only in this way can we ensure that the working conditions can be met, and there is no waste caused by redundancy.
Must meet the requirements of the medium characteristics. For explosion-proof pumps that transport flammable, explosive, toxic or valuable media, reliable shaft seals are required or non-leakage pumps are used, such as magnetic pumps and diaphragm pumps; For pumps that transport corrosive media, corrosion resistant materials are required for convection components, such as explosion-proof centrifugal pumps and engineering plastic magnetic pumps. For the transport of pumps containing solid particle media, it is required that the convection parts use wear-resistant materials, and if necessary, the shaft seal is washed with clean liquid.
Field road layout conditions The road layout conditions of the device system refer to the height of the liquid delivery distance of the liquid delivery direction, some data such as the low liquid level on the suction side and the high liquid level on the discharge side, and the track specifications and their length, materials, specifications and quantities, so as to calculate the comb head and check the cavitation allowance.
The explosion-proof pump has the characteristics of high speed, small size, light weight, high efficiency, large flow rate, simple structure, no pulsation in infusion, stable performance, easy operation and convenient maintenance.
For new self-priming sewage pumps, the possibility of quality problems is very small.
To rule out this possibility, and then there is the installation, the general installation is the installation of engineers will not make mistakes, really wrong even boot can not, let alone use.
After this situation is eliminated, there is only the wrong selection, or the choice of large or small.
