=== OVERVIEW ===
General overview about Oil resisting high lift musti impeller hot oil booster pump
Model QDG Stainless Steel Housing Material and Free standing Installation heat pump swimming pool heater is a horizontal multistage centrifugal boiler feed pump and suitable for transporting liquid (with the contained foreign matters' content less than l % and graininess less than 0. 1mm) and other liquids.
QDG model middle and low pressure boiler fuel pump is applicable to transport medium with temperature of not higher than 105ºC, and is also applicable for small boiler water supply or transporting medium similar to hot water.
QDG model hypo high pressure boiler water supply pump is used to transport medium with temperature of not higher than 160ºC, and is also applicable for small boiler water supply or transporting medium similar to hot water.
=== APPLICATION ===

=== CONSTRUCTION FEATURE ===
Construction feature about Oil resisting high lift musti impeller hot oil booster pump
The Stainless Steel Housing Material and Free standing Installation heat pump swimming pool heater is supported by both ends, and casing portion is sectional.
Connected with motor by flexible coupling For rotating direction, viewing from the motor end.
1. The boiler feedwater pumps are sectional casing,multistage centrifugal pumps. The suction casing, stage casing and discharge casings are rigidly held together by tie bolts. The joints between these casings are primarily sealed by means of metal-metal contact. Simultaneously,O-rings are used as auxiliary seals.
2. The shafts of these pumps are sealed by soft-packing and cooling water. Mechanical seal can be used according to the client's requirement.
3. The rotating assembly is supported by sliding bearings on both ends of the pump shaft. Bearings of pump are forced-lubricated. The oil system is equipped for type QD(G) pump The axial thrust of rotor is balanced by balance disc. And the thrust bearing is also provided which is sed to bear residual axial force caused by the change of working conditions.
The assembly quality of the boiler feedwater pump will result in a notable affection to the performance and the running stability of it and can not be guaranteed unless the technical requirements in the drawings are strictly followed in the assembly, such as on the alignment between the centers of the impeller's outlet and the guide vane's inlet. the uniform values of the sealing intervals of both rotor and stator portions etc.
Covering angle and central line posit ion adjustment. check the equipments at least in the fol lowing three periods and take adjustment:
The first time, both pump and foundation are secured while the motor is not.
The second time, both pump and motor are secured while the bolts on the suck-in and spitting pipeline flanges are not.
The third time is in 24 hours after the pump starts running,then secure both pump and motor
=== OPERATING TIPS ===
Attentions when operate Oil resisting high lift musti impeller hot oil booster pump
The boiler feedwater pump is allowed to run within the set parameter range only.
The pump is not allowed to run with the spitting valve closed or closed to a little opening, or it will be caused heated and duration lowered. Each pump is required to run under the special parameters so as to guarantee the flow of it if mounted in a parallel system.
The pump can not run with the suck-in valve closed, or it may be dried moving to cause parts damaged.
The medium the pump transports can not contain air or gas, or both flow and head of the pump may not be accurately measured and, meanwhile, grinding maybe produced to damage parts.
This pump is not allowed to transport any material with grains, or both pump efficacy and part duration may be lowered.
To keep the boiler feedwater pump in a high effective and stable work, it must be often repaired, the items of repair and the interval between every repair depend on the working condition and running state of it.
=== DRIVER ===
Driver about Oil resisting high lift musti impeller hot oil booster pump
The boiler feedwater pump is driven by the motor through the coupling The gear, membrane coupling and hydraulic coupling can be used according to client's requirements. The pump can be driven by turbine or motor.The rotating direction of pumps are clockwise when viewed from the driving end.
