Products made of stainless steel have gradually entered industrial applications because of their long service life, not easy to rust, and green environmental protection. Stainless steel pipeline pumps are among the best. The stainless steel pipeline pump included in the stainless steel pipeline pump has been widely used in the market in recent years, and is loved by the majority of users because of its corrosion resistance, long service life, light weight, safety and hygiene. Moreover, the cost of construction is comparable to that of ordinary sewage pumps, because the price of its brown metal has continued to increase over the years, and the price is almost the same. The used stainless steel material is a green and environmentally friendly material, which can be recycled 100%, so in recent years, it has become a leader in stainless steel high temperature and corrosion resistant submersible pumps. Especially in recent years, countries in the food industry have put forward higher requirements. Stainless steel materials have gradually entered the stage of history because of their safety and hygiene. For rigid requirements, stainless steel pump products represented by stainless steel submersible pumps have begun to shine in food products. With the sharp increase in the market, the stainless steel pipeline pump industry is facing new technological innovations. Various companies are also competing to launch their own killers, constantly improve their R&D teams, and study related core production technologies, so as to improve their competitiveness in the market. Pump products represented by stainless steel pipeline pumps are leading the entire pump industry to move forward, and the raw material market driven by this, new stainless steel materials continue to come out. Various patented technologies and the continuous improvement of specifications are constantly driving the entire industry chain to a higher and more orderly goal. At the same time, it is also expected that pump products led by stainless steel sewage pumps will go abroad and become more popular in the world. Play the pride of Made in China on the big stage.

What are the filling methods of single-stage centrifugal pump There are two main water filling methods before the start-up of single-stage centrifugal pump: one is to fill water by assembling the bottom valve, which is a one-way valve installed at the inlet of the inlet pipe. The disadvantage of this method is that the head loss of the bottom valve is large, which affects the device efficiency of single-stage centrifugal pump; The other is water filling without bottom valve. The advantage of this method is energy saving. Compared with the pump station with bottom valve, it can save energy by 10% ~ 15%. Manual water filling method: for small pump stations with inlet pipe diameter less than 300mm, a bottom valve is usually set at the inlet of the inlet pipe. Generally, manual water filling method is adopted, that is, water is filled by a water filling funnel (or an inverted ordinary bottle with bottle bottom removed) from the special water filling exhaust hole on the upper part of the pump shell. For small pump stations with inlet pipe diameter less than 300mm, a bottom valve is usually set at the inlet of the inlet pipe, and the pump can also be filled with water from the outlet pipe orifice of the pump (pump station with short outlet pipeline). Because there is no need to buy other water filling equipment, this water filling method is more common in small rural pumping stations Self diversion and water filling method: for the pump house with semi submerged type (i.e. the pump station with the elevation of the inlet pipe and the pump top below the water surface of the inlet pool), the water can be introduced into the pump by itself without manual irrigation and water diversion. The disadvantage of this pump station is that it does not make full use of the water absorption capacity of the pump, and the installation elevation of the pump is reduced, which not only increases the excavation of the foundation, but also inconvenient operation and management; But the advantages are also obvious, that is, it is easy to realize the automation of the pump station and has strong timeliness Vacuum water tank filling method: for small pump stations without bottom valve, vacuum water tank filling method can be adopted. The vacuum water tank is a closed water tank welded with iron sheet, and its volume is three times that of the inlet pipe. The installation position of the water tank should be as close to the water pump as possible, and the bottom height of the water tank should also be slightly lower than the axis of the water pump. The height of the vacuum water tank is generally twice the diameter of the water tank. Vacuum Pump Heat Treatment Guide,Heat Treatment Equipment Liquid Ring Vacuum Pump
