CONDENSATE PUMP TYPE LDTN

CONDENSATE PUMP TYPE LDTN

APPLICATION:
Type LDTN and LDTNA condensat8 pump are used for pumping con-densating water in condenser of thermal (nuclear) plant, also be used for pumping other media which are similar towater in physical and chemical properties. Its range of performanc are as follows: Capacity: 85 〜1940m3/ h Head: 48 ~ 360m Temperature of medium: 8°C(special is up to 1500°C).

CONDENSATE PUMP TYPE LDTN Details

 

CONSTRUOTION:
Type LDTN and LDTN pump are a vertical muilt - stage columnar pump, suction and discharge nozzle are respectively arranged on the barrel and discharge scat and both can be altered on place of 180° 90oor mally degrees; the impeller is closed, the firsti mpeller has two constructions of single and double suction. There are two ways to balance the axial thrust, one is boroe by motor. The other is balanced by pump itself.

BEARING:
The pump has many water - Itihrication bearings thrust of rotor, one balancing drum and a pair of thrust ranged on type LDTN (A. B ) - DP pump to be used thrust. The axial thrust of

COUPLING:
so that bear radial hall bearing are ar-to balance the axial
Pump rotor and line shaft are connected by cutting The connection between pump rotor and motor shaft has thrust is borne by motor which is connected by flanged axial thrust is balanced by pump itself which is connected by flaxible coupling.

SHAFTSEAL:

shaft seal is soft -packing, the mechanical seal can be as sembled according to special ruquirements.

The rotating direction of pump are disigned counter - clockwise when overlooking

AUXIILARY WATER SYSTEN:
Sealing water: Shaft seal must be provided sealing water from outside, the water quality is condensating water, capacity is 0. 3 ~0. 5m3/h, water pressure is 0. 2 ~ 0. 4Mpa, water temperatnre is not more that 38°C.
Cooling water: motors with more than 560kw are installed bearing cooler, which are provided cooling water from outside, water quality is industrial softened water, capacity is 8 - 12m3/h, water pressure is 0. 1~0. 2MPa, water temperature is not morethan 38"C. other pumps are borne by the thrust bearing of motor.
