Product introduction of wear-resistant multi-stage centrifugal pump Wear-resistant multi-stage The centrifugal pump is efficient, energy-saving, wear-resistant and reliable, and has a long life. It is especially suitable for mine drainage. It pumps mine water and other similar liquids with a volume concentration of solid particles not greater than .﹪ (particle diameter less than .), and the liquid temperature is not higher than ℃.
Design principles of wear-resistant multi-stage centrifugal pumps Existing multi-stage centrifugal pumps generally adopt a one-dimensional theoretical design to transport clean water. Our company's wear-resistant multi-stage centrifugal pumps used in coal mines pump coal water containing solid particles. The design theory of two-phase flow is added to the pump's suction performance and hydraulic design, which increases the pump's suction head, reduces the impact wear of coal water in the pump, and can effectively convert energy, thereby improving the efficiency of the pump and extending the time Pump life.
Product features of wear-resistant multi-stage centrifugal pump The wear-resistant multi-stage centrifugal pump is a segmented horizontal multi-stage pump. The suction port is horizontal and the discharge port is vertically upward. The water pump is directly driven by the prime mover through a coupling. Looking at the pump from the prime mover end, the pump rotates clockwise. The pump is mainly composed of four parts: stator, rotor, bearing and shaft seal. The stator part is mainly composed of suction section, middle section, discharge section, guide vane, etc. Each section is clamped with tightening bolts to form a working room.
The rotor part is mainly composed of shaft, impeller, balance plate and bushing. The shaft transmits power to the impeller to make it work. The balance plate is used to balance the axial force. Replaceable bushings are installed at both ends of the shaft to protect the shaft.
The bearing part includes two types: rolling bearings and sliding bearings. Rolling bearings are mainly composed of bearing bodies, bearings and bearing glands, etc., and are lubricated with grease. Sliding bearings are mainly composed of bearing bodies, bearing caps, bearing bushes, dust disks, oil level gauges, oil throw rings, etc., and are lubricated with thin oil.
The shaft seal adopts packing seal, which mainly consists of the water inlet section and the sealing box body, packing and water retaining ring on the stuffing box body. It seals the liquid in the working chamber and plays the role of water sealing, water cooling and water lubrication. The water seal water comes from the pressure water in the pump.
Performance parameters of wear-resistant multi-stage centrifugal pump
The motor drives the impeller to rotate through the pin coupling direct-coupled pump. The blades in the impeller force the liquid to rotate and do work on the liquid, increasing its energy. The liquid is Under the action of centrifugal force, it is thrown around the impeller, and the speed energy is converted into pressure energy through the guide vane flow channel. The liquid is collected through the guide vanes and flows into the next stage impeller, and the above impeller working process is repeated. When the liquid in the first-stage impeller is thrown out, the pressure in the inlet of the first-stage impeller is lower than the pressure in the water inlet pipe. The new liquid is sucked into the first-stage impeller under the action of this pressure difference, and the liquid continuously flows from the pump Internal outflow.
