There are several reasons that cause water circulator pump do not start. 1. Problems with power supply: You should check the plug and socket and the cable. Check circuit breaker in electrical panel. 2. Capacitor not working: Needs a new capacitor, not expensive. 3. Air pressure in water pressure tank too high: Reset air pressure in pressure tank. 4. ...
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 ...
Shinhoo mechanical pump can be divided into PH series ,PUN series and MHI series. PH series are famous for its convenient installation ,compact structure, saving space, low noise and long service life. This kind of circulator pump can be used in hot water circulation and heating system, solar energy, air energy, air-conditioning as well as clean water pressurization system and industrial circulati...
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...
Ⅰ.Leakage Cause 1:The worn shaft causes the can damaged. Solutions:1.Test the motor resistance. If it is normal, replace the shielding cover- rotor assembly. 2.If the motor is burnt out, return it to the factory for maintenance Cause 2:During the maintenance of the water pump, the sealing gasket is poorly installed and deviated Solution:1.Reinstall the gasket. Ⅱ.Burning Cause 1: Burning caused by ...
