Direction for use of DC submersible slurry pump

When submersible slurry pump dealing with the slurry containing a lot of impurity particles, a filtration net is placed on the water inlet, this can reduce the the impurity particles into the pump body, and reduce probability of pump be stuck and prolong the service life of slurry pump. Using time of slurry pump should not be too long, if you have a spare pump, it is best to take turns in the form of operation work.

Pats of submersible slurry pump have adopted mechanical seal, the use of this kind of slurry pump must guarantee seal water supply, and forbid the anhydrous state operation, avoid burnout of the mechanical seal because of dry grinding. Generally speaking, before the use of slurry pump with mechanical seal, should connect the shaft seal water, and should at least keep the water supply for more than 3 minutes after stopping the pump.

Submersible slurry pump produced by DC Machinery company have good performance and high quality, feel free to contact us if you want purchase this kind of product.


 

The mechanical seal is generally used in the condition of submersible slurry pump has relatively high demand for sealing. When the submeisible slurry pump equipped with mechanical seal liquid and spare parts is not used for a long period of time, mechanical seal part should be filled with the N46 machinery oil to prevent mechanical seal parts rusting and the internal rubber parts losing efficacy. Mechanical seal have the characteristics of no leakage, low power consumption and others. And the most important is not allow to the addition of extra ingredients into the pump body. The disadvantage is that the cost is high, maintenance difficulties, etc..

Adjustment strategy of submersible slurry pump

Motor steering adjustment of submersible slurry pump

1.Motor steering should ensure that the direction of pump is in line with the direction of the regulation, reverse rotation is not allowed, otherwise it will cause the impeller tripping or damage to other components.

2.The adjustment of motor steering should be carried out in the state of completely uncoupled with the pump (that is not put the coupling pin or belt). In recognition of the motor steering to meet the requirements can it be connected with the pump, and will never allow blind starting of the motor.

The adjustment of transmission device of submersible slurry pump:

1.If the slurry pump use the pin coupling to transfer motion, it should be put on the column pin and protective cover well.

2.And if the submersible slurry pump is using the belt to drive, it should be on a good belt, adjust the tension, so that each belt is consistent, and put on the protective cover well.

The adjustment of impeller gap of slurry pump:

1.For packing and pay impeller combined or packing seal type slurry pump, turn the shaft along the direction of the rotation of pump by hand, the shaft should be can drives the impeller to rotate, there should be no friction, otherwise it should adjust the gap of the impeller.

2.For slurry pump with mechanical seal, in the circumstances of mechanical seal is installed in the right way, generally do not adjust the impeller clearance.

Notes of submersible slurry pump application

Submersible slurry pump is the slurry pump that need to work under water, so it is restricted to the structure of must being placed into water, then the motor is arranged on the surface of the water and fixed to maintain the stability of the submersible slurry pump.

When the submersible slurry pump is dealing with the slurry which contain a lot of impurity particles, a filtration net is palced on the water inlet, this can reduce the impurity particles that into the pump body and reduce the probability of pump stuck, and prolong the service life of slurru pump. The using time of slurry pump should not be too long, if you have a spare pump, it is best to take turns in the form of operation work.

Part of submersible slurry pump have adopted the mechanical seal, the use of this kind of slurry pump must guarantee the supply of seal water, and forbid the anhydrous state operation to avoid the burnout of mechanical seal because of dry grinding. Generally speaking, you should connect the shaft seal water befor using the slurry pump that with mechanical seal, and maintain the water supply at least three minutes after stopping the pump.

The mechanical seal is generally used in the condition that the submersible slurry pump has the relatively high demand of sealing. When the submersible slurry pump equipped with mechanical seal has not been used for a long period of time, we should fill the N46 mechanical oil with the mechanical seal parts to prevent the seal parts from rusting and the internal rubber parts losing efficacy.

The mechanical seal has the characteristics of no leakage, low power cosumption and others. And the most important thing is that the addition of extra ingredients into the pump body is not allowed. The disadvanges of the slurry pump is that the cost is high,maintenance difficulties, etc.

Submersible slurry pump usage and features

YZS series submersible slurry pump is with structure of vertical single stage and single suction system overhung centrifugal pump.It is made of abrasion-resistant alloy, it can transfer medium with high concentration particle .The normal submersible length is 1.3/1.5m , customized length is available .There is no bearing and Gland Seal between impeller and pump body , so the slurry pump is maintenance -free and high temperature resistance , the slurry pump is the ideal centrifugal pump for feeding to decanter centrifuge , and feeding from mud pit for to the shale shaker on the mud system , it can also be used as feeding pump for desander and desilter .

This series of pump is mainly used in environmental protection  new building materials , coal washing , municipal engineering , thermal power, gas coke plant , oil refineries , steel mills , mining , paper industry , cement factories , food factories , add steam concrete, printing and dyeing and other industries , strong suction of fluid , heavy oil , diesel , dirty fluid , mud , mortar , sand and city pollution discharge flow sludge , as well as containing coal , ash liquid .
