NewmarkSubmersible sewage pumpIt needs to be kept in case of need

　　 The working properties of the two pumps are also different. Because the sewage pump is driven by a motor, it generally has good voltage impact resistance. The submersible pump is of the type of quick opening and quick closing, so it usually uses some small Flow and small pressure.　　Under the action of auxiliary devices, it can transport the slurry, and because the sealing device itself is special, it can also ensure the internal and external balance of the submersible slurry pump during transportation, so that the pressure at both ends of the equipment can be balanced during normal useNewmark,　　The main and feature of self-priming pump is self-priming capacity. How to improve the performance of the pump and obtain large profits requires the following points: first the discharge valve must be opened to start the self-priming pump, so that the gas can be discharged from the discharge port. Secondly, there should be enough liquid in the cavity of the self-priming pump, otherwise it will not　　 repair and level the welding part of the submersible slurry pump with a file, clean the part to be bound with alcohol again and wipe it dry.Lieto,NewmarkRubber lining submerged slurry pump, the tape shall be stretched twice,NewmarkIrrigation deep well pump, and the positions of the three joints shall be staggered for a certain distance in order to prevent short circuit.　　Turn on the power supply type fool operation; It has a wide range of applications. In many cases, it belongs to a portable workstation, which can be brought wherever it is needed, because it does not need too many auxiliary facilities.　　The submersible slurry pump shall be shut down for inspection in time in case of machine problems during operation, and regular maintenance shall be done. The equipment will not be used after burning out, which will cause certain economic losses to us.

　　Second, the power used is not matched, so the motor temperature will be too high after long-term overload operation; In addition, frequent startup during use will also lead to fever, so I　　 For protection during operation, a temperature sensor is generally installed on the stator to detect the temperature of the stator. In case of dry operation due to lack of medium, the wear of the stator and rotor will be very large, and the temperature will increase with friction, further increasing the wear. therefore　　Causes: there is air or gas accumulation in the water inlet pipe of the pump, or the bottom valve is not closed tightly the water supply is not satisfied, the packing of the vacuum pump leaks seriously, and the gate valve or flap valve is not closed tightly.High quality brand,　　.　　If the shaft seal is not properly selected, it will not only require frequent maintenance during operation, but also leak a large amount of transmitted liquid.　　 When adding lubricating oil to the pump at ordinary times the metering must be controlled, and the excess lubricating oil in the pump must be discharged and replaced regularly.

　　After the submersible slurry pump leaves the factory, there is generally only outgoing cable, and the user needs to connect it separately during installation. If the connection is wrong, it will seriously affect the normal operation of the pump, so we should follow the correct steps to connect.Installation material list,NewmarkWQ submersible sewage pump,　　First, let&#;s talk about the familiar vertical slurry pumps. Here we refer to ZJL and SP submerged slurry pumps. Strictly speaking, the submersible slurry pump is also a vertical slurry pump, because its axis is basically vertical when it works, but it can be completely immersed in water when it runs, so it is a good choice　　Static water level refers to the water level before the pump is started.　　 First, screw down the bolts on the side bearing pressure cap, and then remove the nuts used for the connection between the three parts: discharge section, stuffing box body and bearing body; Then screw off the round nut on the shaft, bearing gland and retaining sleeveNewmark,　　 Pipeline layout: Firmly support the water pipe and drain pipe to prevent the force of the pipe from acting on the submersible slurry pump.　　 Selection of pipeline diameter: the selection of pipeline shall consider the one-time purchase cost, long-term operation cost and operation reliability.　　Commodity.
