2、Structural drawing




Structure specification

Except pump head(including pump shell、spiral case、front and back fender 、impeller and so on), therest of GMZ series pump are similar and adopt the same driving mechanism, in the following, giventhe instruction to pump head、shaft gland part and driving part respectively:

1. Pump head: the GMZ series pump is dual-pump shell structure, that is front and back pump shellas well as changeable flow parts (including impeller、spiral case、front and back fenders), the backand front fender adopt gray pig iron or ductile cast iron for manufacturing, it is open in middle invertical way and use bolts for connection, there is spigot on the back pump shell and connected withbracket with bolts, additionally, the discharge opening of pump can be installed by eight anglesrotation, the back and front cover plates of impeller are equipped with back blade for reducing theleakage, and so the useful life of pump can be improved greatly. Between the impeller and shaft,adopt threaded connection for prevention of reversion. For each kinds of pump, the inlets aredesigned to be horizontal direction, when seen from the driving direction, it rotates clockwise.

2. Shaft gland part: there are three types for shaft gland, that is auxiliary impeller shaft gland、stuffing shaft gland and mechanical sealing.

(1) Auxiliary impeller shaft gland: if the single-stage pump or the first stage pump of multilevelseries pump whose positive pressure of inlet is no less than 10 % of the outlet value, can useauxiliary impeller shaft gland, because it has the features like no dilution to pulp and good sealingand so on.(2) Stuffing shaft gland: the structure of stuffing shaft gland is simple and easy to maintain, for theindustrial and mining district where is not suitable to use auxiliary impeller shaft gland, can adoptstuffing shaft gland.(3) Mechanical sealing: For the place where is not suitable for using the two above shaft glands, canadopt mechanical sealing for reducing the maintenance times of

3. Driving part: for this series pump, adopt the same series driving system including bracket、bearingassembly, the pump shaft has many advantages, such as large diameter、well rigidity and shortcantilever, so there is no deviation and vibration when used in bad environment , choose uniserialconical roller bearing and deep groove ball bearing, with the combination of these two bearings, themaximum axial or radial load can be improved greatly. Additionally, use thin oil for lubricating thebearing and there are end covers at the two ends of bearing body and can prevent the bearing fromthe pulp pollution, besides, there are two rubber hose connecter, which can be connected with watersource, installed onto the bearing body for cooling down the bearing chamber, and so, this pump canbe used in high temperature environment without fault and long useful life.

4、Points for attention for assembly

1、Bearing assembly assembling: before assembly, preheat the bearing cone within 120℃, the deepgroove ball bearing must be close to fillet whose two sides are uniserial conical roller bearing. Whenassembly the uniserial conical roller bearing, adjust the washer at rolling bearing end cap forguarantee of axial clearance, after adjusting, rotate the shaft manually for making the rotate flexibly.2、Shaft gland assembling: the stuffing shaft gland assembly consists of stuffing-box、shaft liner、packing ring、packing and packing gland and so on. Selection of packing: if the working pressure ofpump is under 1MPa, adopt asbestos fibre soaking mica as packing, while the pressure is higher than1 MPa or convey the corrosive slurry, adopt asbestos fibre soaking polyfluoroethylene as packing.For the mechanical sealing pump, the pump has been debugged before leave factory, there is no needfor adjusting by users.3、Pump head assembling: fasten the back pimp shell onto bracket and install the stuffing-box intoback pump shell, then use back fender positioning nuts to install back fender, put the O-ring ontoshaft with bond, and install auxiliary impeller as well as spiral case, next, use the bolts and fixedpressing plate to fasten the spiral case onto back pump shell, at last, install the front fender and pumpshell, then make the front pump shell and back pump shell be fixed together and screw down thebolts. Additionally, when assemble, put the sealing O-ring of stuffing-box and fender、back and frontfender and spiral case in correct position and impact it.

5、Operation

1. Startup: before start, check each unit as the following procedure:




(1) The pump shall be installed onto reliable foundation without vibration, then screw down all theanchor bolts.(2) The pipeline and valve shall be equipped with holding frame. When screw down the connectingbolts, the metal liner of some pumps may be higher than flange, so the bolts shall be screwed downproperly in case cause damage to sealing washer.(3) Rotate the rotational shaft manually to check is there is any abnormal noise, if any, adjust theclearance of impeller.(4) Check the rotation direction of motor to see if it is the same to the direction of arrow.(5) When direct connection driving, the pump shaft and motor shaft must be centered accurately, andthe pump shaft shall be parallel with motor shaft when use belt for driving, and adjust the position ofgrooved pulley for making it vertical to trough belt in case cause cute vibration and friction.(6) There is one stub tube which can be removed fixed onto the suction pipe of pump, it isconvenient to carry out maintenance due to its special structure.(7) Shaft gland inspection: check the water quantity and water pressure in shaft gland to see if theyare reasonable; adjust the forcing screw of packing gland for changing the degree of tightness; thenadjust the shaft gland, the leakage from packing gland should be seen as blob and blob effusion. Thepacking should be kept not too tight, otherwise, the shaft liner shall be hot and at the same time,energy consumption shall be increased. While the packing is too loosening, there may be too muchleakage, generally, the water pressure of shaft glad shall be higher than pump outlet by 35 KPa. It issuggested that the water quantity of shaft gland shall be controlled at the range of 0.15L/S -2.1L/Saccording to different model. Additionally, for the pump equipped with mechanical sealing, putthrough the shaft glad water before open the pump.

2、Running

(1) In the process of running, check the pressure and flow rate of water in shaft gland frequently andadjust the packing gland or change the packing for ensuring there is less clean water going throughthe shaft.(2) Check the running condition of bearing assembly, before start the pump, add #20 or 30lubrication oil into bearing body, and connect the rubber hose connecter with cold water (No needfor cold water for 18.5KW below). The oil quantity of bearing shall be proper and clean and shouldbe added termly.(3) The performance of pump shall be degraded with the increase of the clearance between theimpeller and fender, so adjust the impeller forward in time for keeping the pump running in highefficiency. If the friction is serious, the spare parts shall be changes. Check the spare partstermly andestimate the useful life of spare parts in case cause serious consequence due to the failure of spareparts.

3、Termination of pumping

Before termination of pumping, make the pump draw out a certain clean water for removing theslurry, then close the pump、valve、shaft gland water and cold water in bearing body in turn.




6、Care and maintenance

In order to make the pump run safe with long useful life, must carry out daily maintenance. Whencarry out maintenance, the following aspects shall be paid attention:1、Maintenance for shaft gland:Check the water pressure and quantity of shaft gland, keep a certain clan water to flow through theshaft all the time, check the packing gland termly as well as packing. If the packing is not enough,change it. Besides, the water pressure and quantity of shaft gland shall be in accordance with theabove requirements. For the pump equipped with mechanical sealing, the mechanical sealing partsshall be added with N45 engine oil in case rusty of this part and aging of inner rubber.2、Adjusting for impeller:In order to keep high efficiency running, adjust the clearance between the impeller and front fenderin time. Before adjust the clearance, must stop the pump, then loosen the bolts for compressing thebearing assembly, and screw the nut of adjusting bolt to make the bearing assembly forward, at thesame time, rotate the pump shaft manually as the rotation direction of pump till there is frictionbetween the impeller and front fender. Then loosen the nuts which were screwed down just by halfcircle, then screw down the nuts in front of the adjusting bolts for making the bearing assembly movebackwards, here, the clearance between the impeller and front fender shall be kept at the range0.5-1mm. after adjustment, recheck the impeller rotation to see if it is in normal condition and is theholding down bolts have been screwed down before restarted.3、Lubrication of bearingWhen assemble the bearing assembling, the useful life shall be longer if the assembly is correct andadded with proper lubrication oil as well as proper maintenance, in the processing of running, thepump shall be added changed with lubrication oil, the time interval and injection quantity shall berelated with the rev、bearing spec、continuous duty, on and off times and so on, and so the operatorshould accumulate the 4、operation experience, add to oil reasonably and in time.4、The stand by pump shall be rotated by 1/4 circle so that the bearing can bear the static load andexternal vibration evenly.
