QY single-stage multistage centrifugal oil pump
The QY type oil pump series is redesigned on the basis of the original Y type oil pump series. It is a new product developed to adapt to the upgrading of energy-saving equipment, and has the following characteristics : 1. Bearing body parts The original 35,50,60 bearing bodies are replaced by 45,55,70 bearing bodies respectively, which improves the reliability. The hydraulic model of high efficiency and energy saving is adopted in the hydraulic flow components, which is 5-8 percentage points higher than the efficiency of the original Y-type oil pump ; In order to maintain continuity, the structure type, installation size and performance parameter range of AY type oil pump are the same as those of Y type oil pump, which is convenient for the renewal and transformation of old products ; 4, parts generalization degree is high, the standard parts for several series of products ; 5. Material selection and refining, mainly I, class materials, bearing body and other parts increased to cast steel, cast iron, for cold regions, open-air use, marine provides favorable conditions ; 6, bearing air cooling, air cooling, water cooling three, according to the different use of the pump temperature selection. Air cooling is particularly suitable for areas with water shortage or poor water quality. QY type oil pump can be used in petroleum refining, petrochemical and chemical industry and other places to transport oil, liquefied petroleum gas and other media without solid particles.
QHY vertical, single-stage single-suction submerged pump
QHY vertical, single-stage single-suction subsurface pump is suitable for transporting various types of sewage containing particles or fibers. When the insertion length under the liquid is more than 2 meters, the shaft structure is adopted, and the length under the liquid can reach 7 meters. Mainly used for : power plants, thermal power plants, chemical plants, sewage treatment plants, steel mills, steel mills, paper mills, fiber plants, cement plants.
Vertical multistage condensate pump
The vertical multi-stage condensate pump is suitable for the condensate pump of large thermal power plants, and is suitable for various specifications of 100,125,200,300,600,1000MW turbine generators. It can also be used as a high suction pump for pumping other liquids with physical and chemical properties similar to water. In the conventional design state, the temperature of the liquid does not exceed 80 °C.When it exceeds 80 °C, special design is required.
Single stage single suction high speed spiral flow constant pressure pump
Single-stage single-suction high-speed spiral flow constant pressure pump is a new type of pump developed by our company. Its biggest advantage is that the unit volume is very small, light weight, constant outlet pressure. In function, it can replace some segmental multistage pumps, some reciprocating piston pumps, and replace the constant pressure water supply system composed of multiple multistage pump units, pressure storage tanks and automatic control devices. Single-stage single-suction high-speed spiral flow constant pressure pump unit is very suitable for equipment in ships, ships, boats and fire equipment systems ( fire trucks, fire drones, spray fire equipment ). It can also be widely used in nuclear power industry, petrochemical industry, food industry, industrial and mining enterprises. It is used for fire water supply, boiler water supply, mine drainage, chemical raw material transportation, tap water transportation, hydraulic station oil supply and so on.
