XA  Horizontal Single Stage End Suction Centrifugal Pump

XA  Horizontal Single Stage End Suction Centrifugal Pump

1 PUMP INTRO:

1.2、XA series pump is a horizontal single-stage end-suction centrifugal pump for conveying clear water and liquids similar to water in physical and chemical properties without solid particles, which is used in factories, mines, buildings, fire-fighting, irrigation, municipal water supply and so on.
1.3、The change of performance parameters of pumps with the same specifications can be realized by cutting the outer diameter of impeller,
1.4、XA series pump is simple in structure, reliable in performance, small in volume, light in weight, good in resistance to vapor corrosion, low in power consumption, and convenient in use and maintenance.
1.5、XA pump suitable for conveying the medium temperature of -10 – 85°C, conventional working pressure<1.0MPa; if you need to increase to 1.6Mpa or higher, please specify when ordering.Conventional speed of the pump is 1450rpm and 2900rpm, if you need to run at the maximum speed of 3550rpm (60Hz power supply or with gas or diesel engine), the impeller outer diameter of the fit according to the working condition parameters by our company to provide technical services.
1.6、XA series pump flange pressure level for PN16 (GB9119). such as device pressure has special requirements, according to the production of PN25 (GB9119) to provide, please specify in the selection.

2 PUMP STRUCTURE:

2.1 Shell by the vortex chamber, foot, inlet and outiet flanges are cast together as a whole; the inlet is axial, the outlet is radial.
2.2 The structure of the pump is back-open, maintenance without disassembling the suction and discharge piping; pump through the elastic coupling by the motor or internal combustion engine (diesel, gasoline engine) direct drive.
2.3 The shaft sealing type of the pump is divided into packing type and machine sealing type; among them, the machine sealing type has three types; internal mechanical seal, external
mechanical seal and balanced mechanical seal, and the balanced mechanical seal is used for the working pressure of the pump ≥1.6MPa.
2.4 The bearing lubrication of pump has grease lubrication and oil lubrication for selection.
2.5 Bearing configuration of suspension parts

3 ASSEMBLY AND DISASSEMBLY

3.1 The pump should be checked the appearance quality of each part before assembly and wiped clean before putting into assembly.
3.2 Pre-tighten the fasteners, screw plugs, etc. for each connection on the corresponding parts.
3.3 Pre-placing or fitting sealing rings. gaskets, etc. on the corresponding parts respectively.
3.4 Pre-load sealing ring, packing, packing ring, packing gland, etc. on the pump cover parts in turn; mechanical seal pump pre-press the static ring into the pump cover or machine seal gland.
3.5 install the bearing on the shaft, then install it in the suspension, install the sealing gasket, oil seal, bearing gland in tumn, and put the water retaining ring on the impeller end of the shaft.

4  INSTALLATION

The installation of the pump has an important influence on the operation and service life of the pump, so the installation and calibration must be carried out carefully. Pump shape and installation
dimensions, see the chart. installation and calibration are as follows:
4.1,Remove grease and dirt from the base and place the base on the foundation.
4.2.Check the level of the base with a spirit level, allowing for leveling with a wedge.
4.3,Pour cement over the base and ground bolt holes.
44.After the cement dries and solidifies. the base and foot bolt eyelets should be checked for looseness, tighten the foot bolts when appropriate, and check the level again.
4.5.Clean the support plane of the base, the pump foot and the motor foot plane, and install the pump and motor to the base.
4.6,Keep a certain clearance between the couplings, check whether the center height of the pump shaft and the motor shaft is the same, and adjust it with thin shims to make it concentric.
