The pump is a sectional structure with a one-sided location of the workplaces. The sectional case consists of a set of sections with a connector in the planes, perpendicular axes of the pump. The sections between themselves and the lids are centered on cylindrical grooves, joints can be compacted either due to metal contacts of sealing belts, or with the help of sealing rings. The guides in the pump are pressed in the section. The sections and lids are interconnected by screed hairpins and form the pump body. Bearing brackets are attached to the lids of the body with hairpins. Together with lids, nozzles and supporting paws are cast. The axial force is balanced by the unloading drum, the water from it is diverted into the ring chamber to the first stage. The end seals are mechanical seals of the Tandem type. The residual axial load is perceived by stubborn roller bearings. Carter bearing lubricant.
The dignity Smaller metal consumption and complexity, unlike a double -hub pump.
The pump is designed in accordance with the API610 and fully complies with safety and reliability requirements.
Used to pump products with a temperature of up to 150̊s. />
The design of the pump is determined by three main factors: temperature, pressure and nature of the pumped liquid.
The absorption and pressure nozzles are calculated taking into account the permissible loads on the API610.
/b>
- A simple design with a minimum number of parts to minimize the size and cost of maintenance;
- increased absorption of the first stage;
- Unloading from axial effort using a fasting drum;
- The implementation of the bearing unit without the need to disassemble the entire pump.
