High pressure centrifugal pump working principle :Relying on the action of the rotating impeller on the liquid to transfer the mechanical energy of the prime mover to the liquid. Due to the action of the liquid flowing from the impeller inlet to the outlet, its speed and pressure energy are both increased, and the liquid removed by the impeller passes through In the press-out chamber, most of the ...
Heat pump is a device that transfers heat energy from a low-level heat source to a high-level heat source. It is a energy-saving high-efficiency device that makes full use of low-grade heat energy. It is a new energy technology that attracts much attention all over the world. As we all know, heat can be transferred spontaneously from high-temperature objects to low-temperature objects, but not in ...
Circulating pumps are centrifugal pumps designed to generate a forced circulation in a closed system. Such us heating systems for hot water ,heat transfer systems, forced circulation boilers or reactor circuits ,and they are also used in open systems. The design of a circulating pump is often determined by the frequently high temperature of the fluid handled and the relatively low head which corre...
Recently, the rising oil price called for people’s attention. US President Joe Biden on Tuesday announced the imposition of an energy embargo on Russia, banning US imports of oil, liquified natural gas and coal from Russia over its ongoing military operations in Ukraine. Meanwhile, the European Union, which relies on Russia for some 40 percent of its natural gas supplies, announced earlier Tuesday...
Ⅰ.Noise Cause 1:Impurities that entering the gap of rotating parts makes friction noise. Solutions: 1. Disassemble the pump and take out impurities in the runner. 2. Use water softener to reduce scale formation. 3. Use a filter net to keep the water in the pipeline clean. Cause 2: Shaft abrasion caused by scale and by grinding due to lack of water. Solutions: 1. Change the rotor and impeller. 2. U...
Position: The backwater side of the main engine of heat pump system Installation Direction: Horizontally Note: Avoid excessive bends Attention: 1. Select the water pump with base slotted structure: Condensate will be generated inside the water pump during transporting low-temperature medium, and the slotted base can discharge the condensate in time to prevent the accumulation inside the wat...
What is heat pump system: The natural law is that water flows from high to low, and heat is transferred from high-temperature objects to low-temperature objects. However, in our daily life, in order to meet the needs of agricultural irrigation and domestic water, people use water pumps to send water from low to high, the same to heat. In short, heat pumps are used to transfer the heat energy in lo...
The 2022 government work report states that the energy intensity target will be assessed within the 14th Five-Year Plan, with appropriate flexibility, and that new renewable energy and raw material use will not be included in the total energy consumption control. China has entered a new stage of development, and promoting "double carbon" is an urgent need to solve the outstanding problems of resou...
