The selection of water pumps for wastewater treatment in the petroleum industry is a complex process, which requires comprehensive consideration of factors such as wastewater properties, treatment process requirements, site conditions, economy and reliability. Through scientific and reasonable selection, it can ensure that the water pump performs at its best in the wastewater treatment system and improve the efficiency and quality of wastewater treatment.

Self-priming slurry pumps have strong capabilities in sewage treatment, but they also need to be selected and configured according to specific working conditions and medium characteristics.

The reasons why a small self-priming pump cannot suck water may involve many aspects, which need to be investigated and resolved according to the specific circumstances.

The protection device of the self-priming pump includes electrical protection devices, mechanical protection devices and intelligent control protection devices. These devices work together to ensure that the self-priming pump can operate safely and stably under various working conditions.

Through the implementation of correct measures, the occurrence of idling of the self-priming pump can be effectively prevented, ensuring the normal operation and long-term stability of the self-priming pump.

The working principle of the corrosion-resistant self-priming pump is achieved through the combined action of multiple mechanisms such as self-priming function, the action of rotor and impeller, gas-liquid separation and circulation, and conical nozzle effect and static liquid column effect.

Types of self-priming pump impellers include closed impellers, open impellers and semi-open impellers. Each impeller has a unique structure and characteristics, suitable for different working occasions and media. When selecting an impeller, comprehensive consideration should be made based on actual needs.

Self-priming pumps are suitable for low water level environments, but you must pay attention to the selection of its pumping depth and model power, as well as maintenance during use.

The vacuum-assisted self-priming pump prides itself on its advanced technology and user-friendly design. Its vacuum-assisted system ensures quick and efficient priming, eliminating the need for manual priming, saving time and effort. The pump's self-priming capabilities make it suitable for a variety of applications, including those that are difficult to reach or where water levels vary.

This article mainly introduces the main characteristics and working principle of vacuum assisted self-priming pump
