The order of the outlet valve of the water pump is usually soft joint, check valve, gate valve (or butterfly valve), and the pressure gauge is installed on the water outlet of the water pump and located in front of the check valve. This order design takes into account both the normal operation requirements of the system and the convenience of maintenance.

There are five main leakage points of mechanical seals for pumps. These leakage points vary according to the structure and working environment of the mechanical seal

The pump outlet "check valve" plays an important role in protecting the pump body, ensuring system safety, improving system efficiency, and preventing media contamination.

There are obvious differences between fire booster pumps and pressure stabilizing pumps in terms of definition, use, working principle, application scenarios, performance characteristics, and starting and stopping conditions. In practical applications, the appropriate pump type should be selected according to specific needs to ensure the reliability and effectiveness of the fire protection system.

The calculation of the installation height Hg of a centrifugal pump is a process involving multiple factors, mainly including the allowable suction vacuum height Hs, the total resistance of the suction pipeline Hf0-1, the velocity V1 of the liquid at the pump inlet, etc.

when choosing a voltage-stabilizing pump, in addition to paying attention to its performance parameters and reliability, its noise and vibration levels should also be fully considered.

The reasonable selection of a pressure-stabilizing pump requires comprehensive consideration of multiple factors, including demand, product characteristics, use environment, brand and service. Through comprehensive evaluation and selection, it can be ensured that the selected pressure-stabilizing pump can meet actual needs and has efficient, reliable and economical operation characteristics.

Determining the flow of a fire protection pressure-stabilizing pump is a process of comprehensive consideration of multiple factors. By understanding the needs of the fire protection system, referring to specifications and standards, considering the actual use scenarios, and comprehensive calculation and selection, it can be ensured that the selected pressure-stabilizing pump meets the actual needs of the fire protection system and meets the relevant specification requirements.

The impeller of the submersible pump generates centrifugal force through rotation, sucking the liquid from the inlet and discharging it to the outlet through the pump body flow channel, thereby realizing continuous liquid transportation. Its efficient and energy-saving design makes submersible pumps widely used in many fields.

The machine tool cooling water submersible pump drives the impeller to rotate through the motor, and uses the principles of centrifugal force and fluid dynamics to realize the circulation supply of cooling water, providing the necessary cooling and lubrication functions for machine tool equipment.
