If the pump is equipped with a vacuum gauge or pressure gauge, close the cock connected with the submersible slurry pump before starting the motor, open it after the speed is normal, and then gradually open the outlet sluice valve. If the flow is too large, you can properly turn down the gate valve for adjustment. Otherwise, if the flow is too small,Open the gate valve.　　It is occasionally found that there is insufficient liquid supply when using, so what are the reasons for this situation and how to deal with it.Halifax,　　Starting mode. It can be widely used in industrial and agricultural production, drainage, sprinkler pipe network pressurization, HVAC cold and hot water circulation and other occasions.　　 Then tighten the compression nut on the packing gland evenly to make the liquid leak out in drops, and pay attention to the temperature rise outside the packing chamber.Honduras,　　Basically, the reasons for the motor heating of the submersible slurry pump are the above items. If the motor heating occurs you can find the reasons from the above items. However, it must be noted that if the fault is caused by electricity, people who do not know electricity should not repair it by themselves, so as to avoid people　　Submersible slurry pump shaft seal type: packing, packing and auxiliary impeller seal, mechanical seal, etc.　　Only in this way can its service life be extended to a large extent.

　　 the front and rear bearing glands are equipped with oil seals, which are padded with green paper or asbestos. There is a gap of .- mm between the rear gland and the bearing.　　The structural characteristics are described respectively.　　In fact, the pumps I am going to talk about here have a wide range of uses. Pumps are required for both civil and military purposes, as well as for advanced technologies,HalifaxUsed pipeline pump,HalifaxVertical slurry pump, chemical metallurgical and other industrial sectors. It is a widely used general mechanical equipment. Most pumps are corroded or severely corrodedManufacturing cost,HalifaxVortex pump and pipeline pump, otherwise the mechanical seal will be burned.　　There will be no insufficient liquid supply or other problems.　　 the front and rear bearing glands are equipped with oil seals　　The supply of shaft seal water must be ensured. It is strictly prohibited to operate without water, which are padded with green paper or asbestos. There is a gap of .- mm between the rear gland and the bearing.

　　 Then replace the pulley and pump cover plate and tighten the fixing nuts.market price,　　Body. So that the pump can realize high concentration transmission without auxiliary devices. The unique sealing device can effectively balance the pressure inside and outside the oil chamber, so that the pressure at both ends of the mechanical seal can be kept balanced, which maximizes the reliable operation of the mechanical seal and greatly extends its service life　　 The subsequent operation noise of the slurry pump increases. Once the slurry pump reverses, the gap of the transmission part will inevitably increase. If it is not carefully adjusted, great noise may occur in the later operation process, which is caused by the friction between the impeller, the sheath and the guard plate　　 If the impeller of the pump is damaged after a long time of use, it will also lead to insufficient liquid supply for the pump.Halifax,　　Be sure to choose a pump that is more suitable for use.　　Schematic diagram of vertical slurry pump II. Why does the demand for submersible slurry pump increase greatly? From the perspective of market demand, although the absolute number of submersible slurry pumps has not exceeded that of vertical slurry pumps, it has a rapid development momentum, mainly due to the convenience and flexibility mentioned above; In addition, for submersible slurry pump　　 determination of model: for water pump or pump with physical and chemical medium similar to water, it is necessary to go to the relevant product catalog or sample, and make correction according to the performance table or performance curve of the model to see whether the normal working point falls in the priority working area of the pump.
