The direction of motor must keep consistent with arrow on the Front casing. Before testing running the motor, the motor must be separated from pump. The shafts of Motor and pump are strictly forbidden to rotate reversely。 otherwise some parts will be damaged. 2. Before operating the pump, the packing must be installed. mechanical seal of pump, must ensure that the shaft seal water supplies, it is strictly prohibited without running water, or mechanical seal will be damaged.4. Before operation we must add oil (N32 summer or N46 winter) according to the oil level of oil gauge. Pump is strictly forbidden to operate without lube。 otherwise bearings will be burned out. 5. When Install the coupling or pulley, must first into the pump coupling or pulley and then load the mechanical seal to protect the mechanical seal from the impact damage, 6. When equipping the belt wheel of motor, the shaft of motor should manufactured in according to drawings if the shaft diameter is higher than 65mm so that the belt wheel operating safely.7. Please read this technical manual carefully before installation and operation.Ⅰ USES AND SCOPE OF APPLICATIONType ZJ series Slurry Pump is a new energysaving centrifugal pump. They are innovative in hydraulic designs, structural designs and materials of castings after integrating congeneric products throughout the world. They have many features: high efficiency, reasonable design, reliable operation, long in service time, easy maintenance, and low running costs and so on. The ZJ series pump’s lead their domestic counterparts in various technical performances, with most of them approaching the advanced world level, and widely used for handling abrasive or corrosive slurries in power, metallurgical, mining, coal, as well as chemical industries. For example, flushing ash in power plants and pumping coal slurry in coal preparation plants. They are suitable for handling abrasive and corrosive solidsbearing slurry with maximum concentrations of %(ash) and %(ore).Ⅱ PATTERN、STRUCTURAL FEATURE OF PUMPS The Type of ZJ series slurry pump is divided into two categories, one type is ZJ , as singlestage singlesuction horizontal axial suction centrifugal slurry pump。 Another type is ZJL, as singlestage singlesuction vertical axial inhalation centrifugal slurry pump. 1．ZJ Structural feature and type of ZJ slurry pumps（1）ZJ Pump Structure Feature ① Pump Head It is a horizontal cantilevered slurry doublecases pump. The pump head includes cases, impeller, and shaft seal. Doublecases pump centrally split vertical split direction. Discharge port can be positioned at 8 different position at an interval of 45176。.The outside cases made by HT200 or HT5007, connecting with bolts. The inside cases (volute case, front liner, back liner) made by highchrome alloy or rubber materials.Impeller front and back cover plates with back vanes to reduce leakage and increase operating life, impeller and shaft is firmly connected by laddershaped with disassembly ring, ”O(jiān)” rubber ring is used between liner and volute casing and it is very convenient and reliable.There are three kinds of shaft seal type, expeller shaft seal, packing shaft seal and mechanical seal, see Expeller shaft seal is made of stuffing box, expeller, lantern ring, packing, packing gland and shaft sleeve, see 5 Packing shaft seal is made of stuffing box, spacer sleeves,lantern ring, packing, packing gland and shaft sleeve, see 。 Mechanical seal is made of stuffing box, spacer sleeves, mechanical seal, gland and shaft sleeve, see fig1 5b. ② SupportThe horizontal splitcase has oil lubrication and grease lubrication. Oil lubrication is mainly posed of the bracket body, the bracket cover, shaft, bearing box, bearing, bearing gland, spacer sleeve, nuts, oil seal, water retaining plate, stripping ring parts, see fig 1. The main difference between grease lubrication bracket and oil lubrication bracket is that increased the embedded through cover and oil cup, remove the water cooling device, see figure 1 16a.

The Pump Stage，Ⅰas first stage，Ⅱas second stage； ZJ type slurry pump Pump Outlet Dia.，mm 2．ZJL Pump Structure Characteristics and Model（1）ZJL Pump Structure CharacteristicsZJL type slurry pump is mainly posed of the impeller and volute, back plate, shaft sleeve, support, support plate, shaft, bearing, bearing body parts, etc. The material of the impeller volute and back plate is high chrome alloy. The impeller and shaft connected by screw thread, the volute and support, bearing connected by bolted. Pump shaft and motor adopt coupling to direct drive or belt drive. The bearings ZJL pump adopt grease series of pump is no shaft seal. ZJL type pump structure as shown in figure 2.
