4、izontal centr- ifugal pumps are made by way of improving the design of SLS series vertical centrifugal pumps of this company with the performance parameters identical to those of SLS series and in line with the requirements of ISO2858.The products are produced strictly according to the relevant re-
5、quirements, so they have a stable quality and reliable performance and are the brand-new ones instead of model IS horizontal pump, model DL pump etc. ordinary pumps. They are divided into basic type, flow-expansion type A B C cutting type etc. in more than 250 specifications 3 and with a flow range
6、of 1.5-2400m /h and a head range of 8-150m. And, per the different fluid media and tempe- ratures, model SLWR hot-water pump, mode SLWH chem- ical pump, model SLWY oil pump and model SLWHY horizontal anti-explosion chemical pump etc. series prod- ucts are designed and manufactured and have the same
7、pe- rformance parameters. 1.Compact structure. These series pumps have an integrally Horizontal structure, beautiful appearance and less areaof occupied land, which, comparing with the ordinaryones, is reduced by 30%. 2.Stable running, low noise, high concentricity of assem-bly. By the straight join
8、t between the motor and thepump, the middle structure is made simplified, thus en- hancing the running stability, making the impeller of agood balance of moving-resting, resulting in no vibration during running and improving the environment of use. 3.No leakage. A mechanical seal of antisepticcarbid
9、e alloyis used for the shaft sealing so as to get rid of the ser-ious leakage of the fillings of centrifugal pumps andensure the operating place clean and neat. 4.Convenient service. Service can be easily done withou t removing any pipeline because of the back-door structure. 5.Viewing from the inle
10、t of the pump, the outlet of it can be mounted in one of the three ways, horizontally left-ward, vertically upward and horizontally rightward.SLW SERIES SINGLE-STAGE END-SUCTION HORIZONTAL CENTRIFUGAL PUMPS02WORKING CONDITIONS 1 1.6MPa+ 1.6MPa 0.4MPa 1.6MPa 2 0.1 0.2mm 34 09 5 1.Max.

This pump consists of pump, motor and fundation three parts and its structure is formed by pum
23、p casig, impeller, pump cover, mechanical seal etc. Components.It is a single-stage single-suction ho rizontal centrifugal pump a nd b oth p ump c asing and cover are separated from the back side of the impeller, that is the back-door structural form. For most of the pumps, a seal ring is set in bot
24、h front and back of the impeller to make a balance action on the axial force of the rotor. Both pump and motor are coaxial and a dual-angle conta- Cting-ball bearing structure used on the projected end of the motors shaft can partially balance the residual axial force of the pump.With the straight j
25、oint between pump and m- otor, it is not necessary to calibrate when being mounted. Both of them have a common fundation and a buffer das- hpot of model JSD is used to isolate vibration. The outlet of the pump can be mounted vertically upward, leftward or rightward, flexibly and easily. Outlet to le
