Chemical pump LCZ series standards
LCZ type pump for my company for sulzer Switzerland technology and develop new products, products accord with standard of ISO2858, DIN24256, GB5662, filled the domestic blank, reached the international advanced level, is the basic of the standard chemical pump products, its characteristic is as follows:
First, the hydraulic performance
Pump body port to port or the shuangliu, USES the spiral structure of pressurized water. Cavitation lowest performance curve is wide, smooth operation, low noise, high pump efficiency, save energy consumption.
Second, the support form
This series of pump body and foot support, can withstand external load, directly to the foundation. Pump selection is centripetal thrust bearing, durable, trunnion sizes, can ensure smooth operation. Bearing lubrication way for thin oil lubrication, persistence an oil cup to control the oil level, fully guarantee the bearings work in good lubrication condition, makes the service life of the bearings with the best.
Three, stable forms and axial force of the impeller
For the closed impeller or half open. Most LCZ series pump axial force by the blade or smooth hole back to smooth, the residual axial force bearing.
Fourth, the structure of the shaft sealing system
Shaft seal according to the usage of different, can use packing seal, mechanical seal series, double mechanical seal, mechanical seal. Flush with the outside, the flushing, flushing way to flush seal, in order to ensure good working state and service life of the seal.
Five, seriation and generality
This series of pump a total of 6 kinds of specifications of the bearing frame, 40 kinds of pump model. In addition to the pump body, impeller, the rest of the pieces have universality, especially the parts of the pump cover and seal, high degree of standardization, strong commonality.
After "pull" structure is used to pump and lengthened coupling, maintenance, don't need to remove the import and export line motor, even the whole rotor parts, bearing parts, etc.) (impeller can pull from the rear.
