Torque transmission shaft is the main component. Shaft press strength, stiffness and critical speed OK. Small multi-use horizontal slurry pump manufacturer Axis, leaf roller with the shaft, the distance between the impeller with the sleeve positioned. Modern large slurry pump manufacturer stepped shaft is used, ranging from leaf aperture Round with hot cuff mounted on the shaft, and use involute splines instead of past short key. This method, between the impeller and the shaft is not Gap between the axes does not result in channeling water and erosion, but disassembly difficult. For the inhalation chamber. Its role is minimal hydraulic loss in case of liquid smoothly guided into the impeller, the impeller inlet and make The flow as evenly as possible. According to the structure suction chamber can be divided into: (A) straight conical suction chamber shown in Figure 1-2, this form of suction chamber hydraulic performance, simple structure, easy fabrication. The liquid in the suction chamber straight tapered flow speed is gradually increased, and therefore tend to be more uniform velocity distribution. Straight tapered suction chamber Taper of about 70,, 8o. This form of suction chamber is widely used in single-stage centrifugal water cantilevered on slurr y pump manufacturer. (2) elbow-shaped suction chamber shown in Figure 1-3, is a large centrifugal slurry pump manufacturer and large axial slurry pump manufacturerfrequently used form, this suction One room has a straight in front of the impeller cone shrink tube, so it has the advantage of a straight conical suction chamber. (3) an annular suction chamber shown in Figure 1-4, inhalation chamber for each axis in-plane cross-sectional shape and dimensions are the same. The advantage is the junction Symmetrical structure, simple, compact, small axial size. Drawback is that there is shock and whirlpool, and the uneven distribution of the flow velocity. Annular suction chamber is mainly used for multistage slurry pu mp manufacturer in. Figure 1-3 elbow-shaped suction chamber MI, annular ilk into ‘;, r (4) semi-spiral suction chamber shown in Figure 1-5, is mainly used for single-stage double-suction submersible slurry pump manufacturer, horizontal split multistage slurry pump manufacturer, large Type multistage slurry pump manufacturer and certain single-stage slurry pump manufacturer on the cantilever. Half spiral suction chamber can produce rotational movement of liquid flow, ie There circulation exists, the presence of the liquid circulation around the slurry pump manu facturer axis, causing the liquid into the impeller inlet velocity distribution when it A more uniform, but the import of pre-spin will cause slurry pump manufacturer’s head slightly lower, which reduces the value of the flow rate is directly proportional.
4 vanes Also known as the deflector vanes, guide wheel, sub Radial vanes and runner-type guide vanes two kinds, used multistage slurry pump manufacturer to make Water guide. Radial vane shown in Figure 1-6, which consists of spiral, expanding Loose tube, the transition zone (annular space) and ABM leaves (to Heart Ring out cascade) components. Helix and the diffusion tube portion, said positive lead Ye, the outflow of liquid from the impeller, from the helical part of the collection , The majority of the diffusion tube to pressure energy is converted to kinetic energy into Transition zone, from the effect of changing the flow direction, and then into the ABM Leaves, eliminating velocity circulation and the liquid toward the secondary impeller Imports. Thus, both the guide vane suction chamber and the pressure of the chamber Effect. Flow guide vane type shown in Figure 1-7, the front part of it with Radial vanes are the same vane, radial and later Type missile leaves the guide vane is similar to, but not between them an annular space, and being part of the diffuser vanes with the flow channel outlet Partially connected with the ABM leaves together to form a flow channel. Their hydraulic performance is almost the same, but in the structure of the radial size Style guide vane larger workmanship is relatively simple. Currently multistage slurry pump manuf acturer designs tend to use flow-type guide vanes. Pressurized water chamber is exported to the slurry pump manufacturer impeller outlet flange (right multistage slurry pump manufacturer is to the rear impeller import) over-current portion Points. Its role is to collect the high velocity fluid discharged from the impeller, and the majority of the liquid kinetic energy is converted into pressure energy, and the introduction of pressure water or the rear stage impeller. Pressurized water chamber according to the structure is divided into spiral pressurized water chamber, an annular pressurized water chamber and the guide vane pressurized water chamber. Spiral pressurized water chamber shown in Figure 1-8, it is not only the role of the liquid from the collection, while the diffusion tube will spiral Ministry Of converting kinetic energy into pressure energy of the liquid. Spiral pressurized water chamber has manufacturing convenience, high efficiency characteristics. It is suitable for single-stage single-suction, Single-stage double-suction centrifugal slurry pump manufacturer and horizontal split multistage centrifugal slurry pump manufacturer. Annular pressurized water chamber shown in Figure 1-9, the multistage slurry pump manufacturer in the water segment adopt. Annular pressurized water chamber of the flow channel cross-section plane Product is equal, so the flow rate is not equal everywhere. Thus, whether or not the design conditions design condition always has an impact Losses, the efficiency is lower than spiral pressurized water chamber. Figure 1-8 spiral pressurized water chamber Figure 1-9 annular pressurized water chamber 6 sealing device Centrifugal slurry pump manufacturer seals with sealing ring (also known as the mouth ring, collar) and the shaft seal two parts. (1) Since the sealing ring impeller centrifugal slurry pump manufacturer exporting liquid is high, the population is low pressure, high pressure liquid through the impeller slurry pump manufacturer body Leak back into the gap between the suction Office, and so need to install the seal ring. Its role is to reduce the impeller slurry pump manufacturerleakage between Loss; hand protects the impeller, avoid rubbing the body with slurry pump manufacturer. Sealing ring pattern shown in Figure 1-10, there are Flat ring, angular contact type and labyrinth. General slurry pump manufacturer Use the first two, while high pressure slurry pump manufacturer as single-stage Young Cheng high, to reduce leakage, commonly labyrinth.
