merchandise description

The NL type mEPTTpump is a solitary-stage one-suction vertical centrifugal pump. The main factors are volute, impeller, pump seat, pump casing, support cylinder, motor foundation and motor. The volute, pump seat, motor base and impeller nut are forged iron, have good corrosion resistance and handy processing. The impeller is a a few-piece solitary-chord curved blade. The semi-shut impeller is used, and the malleable forged iron is utilised, so the power is large and corrosion resistance the processing is hassle-free, the passability is excellent, and the efficiency is higher. In orEPTTto reduce weigEPTT and decrease the quantity of turning, the pump shaft is created of substantial quality carbon metal cold drawn steel. 4 skeEPTTn oil seals and bushings are put in in the pump seat to avert shaft dress in and prolong the service life of the shaft. The NL type mEPTTpump can be used vertically or tilted. The footprint is tiny, the volute requirements to be buried in the doing work medium, easy to start, no require to divert h2o, and the path of rotation ought to be clockwise from the rear of the motor. The size of the main device is offered in different technical specs so that the device can be picked according to the software.

NL kind mEPTTpump use range

1. NL sort multi-function submerged pump is a one-phase solitary-suction centrifugal pump utilized in mining, paper producing, printing and dyeing, environmental security, graphite, mica, EPT, EPT, oil refining, petroleum, chemical, farm, salt discipline, iodine field, dyeing, Brewery, food, ferEPTTzer, coking EPTT, building, marble EPTT, EPT EPT, mud, quicksand, mEPTTpond, sewage pond, sewage liquid, sewage pumping thick liquid, charging and suspended substance sewage procedure, can also be employed for coal EPT drainage and A fluid conXiHu (West EPT) Dis.Hu (West EPT) Dis. mud.

2. If blended with higher-force drinking water pump and water gun, the EPT mechanized earthwork engineering unit can be utilized for land leveling, excavation and transportation of little h2o conservancy projects such as dredging and ponding of rivers and ponds, and city air protection operates. engineering.

3. Fish farming is employed to deliver water to very clear ponds, fish ponds to boost oxygen, and so on.

NL series sewage cement pump disassembly and installation

Initial, disassembly and installation

(1), disassembly

one. Disassemble the electric powered raft or the fixed plate and the outlet pipe.

two, get rid of the volute and the impeller butterfly, frivolously broaden the again of the impeller, take away the key impeller

three. Disassemble the EPTn fifty percent coupling, eliminate the essential, then disassemble the motor seat and independent it from the assist cylinder.

four. Disassemble the pump foundation and the support cylinEPTTbolts to make them separate.

5. Get rid of the bushing and bearing from the shaft.

(two), set up

one. Check all areas for defects. Utilize a layer of butter to each sides of the paper pad and include two-thirds of the butter to the bearing.

two. The skeEPTTn oil seal must be filled with butter and placed in the pump foundation, and then mounted on the bearing.

three. Implement a butter to the -ring seal inside of the bushing.

four. Put it on the motor base, put the paper pad, the oil reXiHu (West EPT) Dis.Hu (West EPT) Dis. ring, and install the shaft and the assistance cylinEPTTwith screws.

5, set the paper pad, set up the bearing, bushing, crucial, pump seat and impeller, tighten the impeller nut and rotate the impeller by hand, the rotation can be fleXiHu (West EPT) Dis.ble.

six. Place the paper pad on the pump casing, resolve it with screws and put in the filter. Then pull the impeller by hand and change it fleXiHu (West EPT) Dis.bly.

seven. Install the essential and the EPTn coupling on the pump shaft, set up the important and the active coupling on the motor shaft, and then fix the motor and the motor seat bolt. Soon after set up, the aXiHu (West EPT) Dis.al clearance amongst the energetic coupling and the EPTn coupling should be 1~one.five mm.
