Product overview

Adopt unique single or double channel impeller flow channel structure, greatly improve the through capacity of the contamination, can effectively by fiber material with pump diameter is about 50% of pump diameter and solid particles. The overall structure is compact, small volume, low noise, energy-saving effect is remarkable, maintenance is convenient, without having to build pump room, working while being submerged into water, and greatly reduce the project cost; Installation fast; Eliminate the noise and the heat problem.

Application field

WQ series submersible sewage pump can meet the municipal engineering, building construction, industrial sewage, wastewater treatment and environmental protection requirements, can be used for lining of sewage containing solid particles and all kinds of long fiber, wastewater, rain water and sewage, etc.

Q:Why is the submersible pump tripped on an electrical switch?There is no electrical leakage protection, directly connected to the circuit breaker, and when the switch on, the circuit breaker jumpedI checked the line is good, the pump did not break down, is not the water pump?: Submersible pump cable or motor insulation is damaged.3) motor water solution

Q:Shielding pump is the main drawback of electricity? How much does it cost more than an ordinary centrifugal pump? Is there any noise in the running of the canned pump? How much is it lower than the noise of the common centrifugal pump?: The ordinary centrifugal pump is driven by coupling the pump impeller shaft is connected with the motor shaft, the impeller and the motor rotates while working and shielding pump is a kind of non seal pumps, pump and motor is sealed in a medium filled by pumping the pressure vessel, the pressure vessel only static seal and, by a group of wires to provide a rotating magnetic field and rotor drive. The structure eliminates the rotary shaft sealing device of the traditional centrifugal pump, so the utility model can be completely free from leakage.

Q:Water pump outlet valve sequence: Design specifications detailed manual instructions, divided into two cases:1, pump water first check valve, suitable for small caliber pipeline, gate valve to protect the non-return valve, not damage function;2, pump water out of the first gate valve, check valve for large diameter pipe, at this point valve easy to open and close;The setting of the check valve is mainly to avoid the high reverse speed of the pump and the condition of the submerged pump house. Set in the suction port of the pump, then stop the pump water flow will still affect the pump. In addition, the pump suction should try to avoid installing too many pipe fittings, so that the pump can maintain sufficient cavitation margin.

Q:What is the difference between swashplate pump and crankshaft pump?: In hydraulic system:Axial piston pump is the use of parallel with the transmission shaft in the plunger plunger reciprocating movement of the volume changes generated by the work. As the plunger and the plunger hole are circular parts, processing can achieve high accuracy with the high volume efficiency, stable operation, good flow uniformity, low noise, high working pressure, but the hydraulic oil pollution is more sensitive, more complicated structure, high cost.

Q:Types and differences of pumps: Classification and working principle of pump by structureClassification of pumpsInvolved pump standard product types are also very much, a centrifugal pump, metering pump, screw pump, reciprocating pump, hydraulic pump, submersible pump, oil pump, water pump, pressure test pump, vortex pump, cryogenic pump, vacuum pump, roots pump, molecular pump, gear pump, mud pump, corrosion-resistant pump deep well pump, water pump, mixed flow pump, axial flow pump, boiler feedwater pump, liquid pump, injection pump, chemical pump, pump plugging and no leakage pump, plastic pump, fire pump and so on, there are many. Its name is divided according to some conventional classification methods such as pump vane pump volume, pump etc., some are divided by purpose such as sewage pump, pump and other health, some names are more random as diffusion pump, liquid nitrogen pump. As long as the production of this product, with standard requirements, through a certain application and approval procedures may produce a new The standard, but sometimes the content also has a repeated cross, quite. The domestic and foreign standards, the domestic standard is more than the number of foreign standards. In general, such as centrifugal pumps are widely used, the production history of the pump more standard (total standard centrifugal pump up to more than 100). As new standard pump leakage pump this rapid development is relatively small. This paper introduces the structure and working principle of the pump according to the classification of the

Q:Direct connection pump What is straight pump and non direct pump? What's the difference in structure?: Direct connected pump: pump impeller installed directly on the motor shaft, it looks like a whole, relatively compact, simple installation, but the general power is relatively small (big bad processing connection, but not absolute);Non direct pump: pumps and motors are independent of each other, through the coupling torque transmission, the structure is relatively large, complex installation, to adjust the level / concentricity and so on, the general power is relatively large

Q:What does "anti pump" mean in pump operation?: The pump again is the pump, the theory is the plugging problem can be solved, but if you are against the pump after pump has been plugging serious, and pump has been unable to solve the plugging problem, finally the worst solution is a split pipe, if the situation under enormous pressure will only exacerbate the plugging

Q:What are the conditions required for hydraulic pumps to complete oil absorption and compression?: Volume conditions: oil absorption cavity from small to large, complete oil absorption, oil pressure chamber has become smaller, complete pressure oil.Sealing conditions: the hydraulic pump itself should have good sealing

Q:How long does the fine stone pump need maintenance? What should I pay attention to?: Daily maintenance of concrete pump, that is, routine maintenance in use, including inspection, cleaning, lubrication, fastening, adjustment, leak hunting, supplement of hydraulic oil, etc.. 8.1 hydraulic components inspection, due to the complexity of the equipment, we recommend practical experts to carry out the inspection of hydraulic system. If a fault is found, check the cause and repair the entire loop before proceeding to any operation. - found that oil has diarrhea, excluding leakage reasons. - inspect safety valves, hydraulic systems, steel tubes and hoses, fittings, cylinders, and find any wear and tear (pipe explosion may cause very serious consequences)

Q:Filter backwash pump for what use, what is the principle of work ah?: Regeneration of the filter medium is required to regain the filtration capacity of the medium. The regeneration process is mainly accomplished by the backwashing pump (the backwash pump is not a special pump, referring to the pump for the completion of the process). The working principle is through the cleaning liquid from the downstream of the filter into the backwash pump (alkali, acid and water), reverse flushing filter medium, cleaning liquid discharged from the upstream, this process can be attached to the dielectric surface and internal impurities washed away.
