(1) Structural characteristics of SZP type slurry pump

Model and Significance of SZP Slurry Pump

① Pump head
The pump head part of SZP slurry pump includes pump casing, impeller and shaft seal device. The pump head and the bracket are connected with bolts. According to the needs, the outlet position of the pump can be rotated at 45 ° intervals to eight different angles to install and use.
The pump casing of SZP slurry pump is of double shell structure. The outer layer is a metal pump casing (front pump casing, rear pump casing), and its material is usually HT200 or QT500-7; the inner shell can be made of high chromium alloy cast iron (including volute, front guard plate, rear guard plate), or Made of rubber (including front volute and rear volute)
The impeller is composed of front cover plate, rear cover plate, blade and back blade. The blades are twisted blades, usually 3-6. The back blades are distributed on the outside of the front cover plate and the rear cover plate, and there are usually 8 blades. The material of the impeller is high chromium alloy cast iron, and the impeller and the shaft are threaded connection.
The shaft seal device has three types: auxiliary impeller packing combination seal, packing seal and mechanical seal.
The combined sealing type of auxiliary impeller and packing is composed of stuffing box, auxiliary impeller, water seal ring, packing, packing gland and shaft sleeve.
The packing seal type is composed of packing box, spacer sleeve, water seal ring, packing, packing gland and shaft sleeve, as shown in Fig. 5a.
The mechanical seal type consists of stuffing box, spacer sleeve, mechanical seal, gland and shaft sleeve, as shown in Fig. 5b.

② Bracket part
The bracket part has two structures: horizontal middle opening type and cylinder type.
Open bracket with thin oil lubrication and grease lubrication of two types. The thin oil lubrication bracket is mainly composed of bracket body, bracket cover, shaft, bearing box, bearing, bearing gland, stop sleeve, nut, oil seal, water retaining plate, disassembly ring and other parts, as shown in Figure 1. 150SZP and above pump type also with water cooling device. The main difference between the grease lubrication bracket and the thin oil lubrication bracket is that the embedded through cover and oil cup are added, and the water cooling device is removed, as shown in Figure 16a.

The cylindrical brackets are all lubricated with grease and are mainly composed of bracket body, bearing body, shaft, bearing, bearing top sleeve, bearing gland, oil seal, oil cup, water retaining plate, disassembly ring and other parts, as shown in Figure 16b. Cylinder bracket is only suitable for 200SZP and the following power smaller pump type, currently only T200SZP-I-A70, T200SZP-I-A60, T150SZP-I-A60 three specifications.

(2) the structural characteristics of SZPL type slurry pump
① SZPL slurry pump is mainly composed of impeller, volute, rear guard plate, shaft sleeve, bracket, support plate, shaft, bearing, bearing body and other parts. The material of the impeller, volute and rear guard plate is high chromium alloy cast iron. The impeller and the shaft are connected by threads, and the volute, bracket and bearing body are connected by bolts. The pump shaft and motor can be driven by coupling direct connection or belt drive. The bearings of SZPL pumps are lubricated with grease. This series of pumps are non-shaft seal pumps.
