Product Description
MDS Double Suction Self-balancing Multistage Pump
MDSP first-stage double-suction mine self-balancing multistage pump, the first-stage impeller adopts double-suction design, which can effectively reduce the cavitation of the water pump. Due to the absence of wear and axial pulsation of the balance disc, the alignment of the impeller and the guide vane is always in a neutral state, and the efficiency will not decrease with the wear of the balance disc and the forward movement of rotor components like the common multistage pump structure. There is no balance water leakage and volume loss, on the whole, the operation efficiency and service life of the pump are improved, and the efficiency is 5-14% higher than that of the ordinary multi-stage pump.
Model description:
MDSP -- First-stage double-suction mine self-balancing multistage pump;
280-design point flow 280 m3/h;
65 -- The head of single-stage design point is 65m;
8-Series of water pump.
Direction of rotation:
Clockwise rotation as viewed from the motor end to the pump.
Material of main parts:
Pump flow parts are made of wear-resistant ductile iron, cast steel and stainless steel (304, 316, 316L, 2205, 2507, etc.).
Scope of package:
The pump is supplied with motor and base, and can be equipped with functional base or its own base. The manufacturer also provides accessories (including discharge cone pipe, gate valve, bottom valve and check valve) and spare parts (including impeller, sealing ring, guide vane sleeve, balance plate and shaft sleeve).
Structure description:
D, DG, MD, DF, DY pumps are mainly composed of fixed parts, rotor parts, bearings and shaft seals.
1. Partial stator
It is mainly composed of water inlet section, middle section, water outlet section and guide vane, etc., and each section is tightened with a bar to form a working room. The inlet of D-type multistage pump is horizontal and the outlet is vertical upward. DG pump inlet and outlet are both vertically upward. MD, DF and DY pumps have their outlets vertically upward and their inlets are generally horizontal. As required, they can also be produced in the vertical upward direction.
2. Rotor part
It is mainly composed of shaft, impeller, balance plate and shaft sleeve. The shaft transmits power to the impeller to make it work; the balance disc is used to balance the axial force; the shaft is equipped with a replaceable sleeve to protect the shaft.
3. Bearing part
It is mainly composed of bearing body, bearing and bearing gland. In addition to 85-67, 155-67, 600-60 type pump using sliding bearings, thin oil lubrication, the rest of the pump are used rolling bearings, grease lubrication. 85-67, 155-67 can also use rolling bearing structure.
4. Shaft seal
Generally, soft packing is used for sealing, which is mainly composed of sealing body, packing and water retaining ring on water inlet section and tail cover. There is a constant pressure of water in the sealing cavity, which plays the role of water seal, water cooling and lubrication. D type pump water seal generally comes from the high pressure water in the pump, DG, MD, DF, DY type pump comes from the pressure water in the pump or external water supply. DG, MD, DF, DY type pump more mechanical seal.
5. Transmission
The pump is directly driven by the prime mover through an elastic coupling. From the prime mover end, the pump rotates clockwise.
