DY multistage centrifugal horizontal high pressure oil pump

D multistage centrifugal pump adopts the high efficiency and energy saving hydraulic model and has the advantages of high efficiency and energy saving, wide performance range, safe and stable operation, low noise, long life, convenient installation and maintenance, etc. By changing the pump material for the flow part of the pump), seal form and increase the cooling system, D multistage centrifugal pump can transfer hot water, oil, corrosive and abrasive media etc.

DY horizontal multistage centrifugal oil pump is made of cast iron or stainless steel pump body and driven by explosion proof motor. DY multistage centrifugal oil pump is used to transport petroleum oils without solid particles and the viscosity less than 120 CPSThe medium temperature is t-20 ℃ ~ 105℃, and the allowable inlet pressure is 0.6mpa.

DY stainless steel multistage high pressure centrifugal oil pump is used to transport oils and petroleum products without solid grains and the temperature of 20℃ ~ 105℃ with a viscosity of less than 120CPS.

DY multistage oil pump is a single-shell, single-suction, multi-stage segmental centrifugal pump structure, the pump inlet horizontal, vertical upward outlet specific structure is as follows:

1. Stator part

Mainly by the front section, middle section, guide vane, back section, bearing support and balance chamber cover and other parts with the bar and nut into one, front section, after both sides of the section with bolts and nuts fixed on the pump seat

2. Rotor components

Mainly by impeller, impeller block sleeve, balance block sleeve, balance disc and shaft sleeve parts with small round nut, fixed on the shaft with flat key anti-rotation. The entire rotor is supported on bearings at both ends. The rotor is connected directly to the motor by an elastic pin coupling.

In order to compensate the expansion in the last stage and balance between the installation of a gear-shaped pad, pump maintenance should be replaced this piece.

3. Balancing mechanism

This pump adopts the hydraulic balancing device of balancing disc which can completely and automatically balance the axial force. The device is composed of four parts: balancing plate, balancing disc, balancing sleeve and balancing retaining sleeve.
