Stainless steel centrifugal pump

Stainless steel pump has the advantages of corrosion resistance, high strength, light weight and long service life.it is widely used in shipbuilding, rail vehicle transportation industry in recent years.With the development of machinery manufacturing industry, stainless steel pumps will have more wide application prospects.
Stainless steel has high temperature resistance, corrosion resistance, wear resistance and other properties,it play active role in energy, petrochemical, power, mining and other fields.
In the last decade, the stainless steel pump requirement is increasing.Especially the water industry, construction and structure of industry, environmental protection industry, the demand is increasing year by year.
In the water industry, the problem of water pollution during storage and transportation has attracted more and more attention
More effects have proved that stainless steel equipment for water tranportation, storage, purification, recycling, desalination and other water industry is the best.
The advantages are: corrosion resistance, earthquake resistance, water saving, sanitation, light weight, easy maintenance, long service life, low life cycle cost, is Recyclable using green materials.At present, the Tokyo stainless steel pipeline in Japan has reached 76%, the pipe leakage rate from the original 14.7% to the current 7.5%.
Stainless steel tanks are intact after a big earthquake in Osaka, Japan.Recently, Japan developed a corrugated pipe joint, so that the construction cost of the stainless steel water pipe is reduced by 20%, 3% reduction in total cost, reduce the maintenance cost of 3/4.
Stainless steel pump driven by stainless steel industry has a good market prospect.It is predicted that China stainless steel pump market in the last ten years can reach 20-30 billion.
Gelaili is a mainly Stainless steel centrifugal water pump manufacturer,it provide high quality stainless steel water pump to the whole world. Gelaili is a mainly professional manufaturer of shower pump,aquarium water pump,fire pump,coolant pump,dewatering pumps,booster pump,ro booster pump and so on.

Why Ro booster pump in a water treatment system does not work?

Why Ro booster pump does not work?Let's find out the reason. Reverse Osmosis booster Pump is one of the key part of the RO water purification machine,we call it ro booster pump,It is a kind of booster pump be used in the reverse osmosis device, it has the function of self-priming and pressurization. Ro booster pump provide Ro membrane water pressure and water flow,to make Ro rembrane work. Ro membrane is another important component of the RO water purification machine.So Ro water purification machine can give us purifield water. Some times ro booster pump does not work,so the whole system is out of work,there are follow reasons cause the ro booster pump doesn't work: 1,Purifield water tank at a high level or the original water tank is at a low position. 2,Ro water pressure is higher than the protection switch Settings, the controller automatically switched on. 3,Ro booster pump suction pressure is lower than protection switch Settings, the controller automatically discon...

How to exclude the interference from the frequency converter

These problems often occur when you work at regular work and debug the equipment: 1 . When the converter of the heat exchange station is opened , the pressure transmitter shall jump ; 2 . using frequency converter to control the water supply , the voltage transformer is used as a signal for collecting pressure , and the voltage transformer is interfered by the frequency converter ; 3 . When the frequency converter starts up the motor , the voltage change signal is unstable and the jitter is great ; 4 . The voltage transformer ( 4 – 20mA ) shall jump after the frequency converter is started , and the integrated thermal resistance ( 4 – 20mA ) nearby is not affected , and the signal line is not shielded . These phenomena are due to the interference of the frequency converter. Why does the inverter produce interference The inverter comprises a rectifying circuit and an inverter circuit , wherein the input AC power is converted into a DC voltage through a rectifying circuit and a wave loo...

Difference between suction stroke and lift head of water pump

Pump self-priming capacity is also called maximum self suction height.It is the maximum height at which the water is pumped (the vertical distance between the pump and the the liquid surface to be pumped) without fill in water into the pump tunnel. General water level is lower than the location of the pump, you need to pump self-priming capacity.For example ,if we need to pump water from a river ,we will not plan pipe first,so we need a pump which has self-priming capacity. Or we need to pump some corrosive liquid,we can not fill water into the water pump tunnel. Some centrifugal water pumps do not have self-priming capacity,they need to fill in water at first time of using. The pump lift is the height that pump can lift water up.We usually expressed in H,the the unit is meter. The lift of the centrifugal pump is based on the center line of the impeller.The lift Consists of two parts,first is the vertical height from the center line of the pump impeller to the surface of the water s...
