Product Description:

Production Introduction:
WQX.WQXD series pump consists of pump, mechanical seal and motor. Pump is at the bottom part of pump, which is adopted centrifugal impeller. Motor which is monophase or triphase is at the upper part of pump and seal is used where pump and motor combine, which is a kind of double-face mechanical seal,"0"rings are applied to all static joints. This series pump has many merits, which are well-set,high head, high efficiency, easy-handled etc. The pump’s key part seals are completely adopted with high-quality metal alloy and carborundum as material.

This series pump is widely used for sewage treatment of city construction discharge forarchitecture projects, hotel, mine, pond, dyeing and printing, paper making and textile industries. It is the ideal tool for transportation of sludge, slurry, living sewage, feces and stale wastes, solid grains fiber, paper chips, and sandy soil etc..

Work Conditions:
The pump can work properly and continuously under following op?erational conditions:
1.Medium is not corrosive. Sand contents should be max.2.5% by volume and granular size should be max.1.8mm.
2.Medium temperature shouldn’t be over 40"C and PH should be 4-10. The pumps should be operated within rated head.
3.The pumps should be fully submerged into water with depth of less than 3m and max. The pump should bemin.0.5m over the water bottom and not be inserted into sludge.
4.Power frequency should be 50Hz,single phase voltage 220V,three-phase voltage 380V,and voltage fluctuation should be 0.9-1.1 times than the rated.

Q:What is a positive displacement pump? He Weizheng displacement?
The principle and structure of positive displacement pumps are similar to those of hydraulic motors. Positive displacement is the pump outward to provide flow and pressure, that is, conventional pumps. A negative displacement pump is a hydraulic motor that rotates by external pressure and flow.
Q:Metering pumps related matters
1., exports higher than imports, avoid siphonage2. the pump head and the injection valve require vertical installation3., the attached pipe can be tightened by hand, please do not use the tool; the thread does not use the raw meal belt4. the supply voltage is stable and grounded5. installation environment clean, spacious, well ventilated) 1) metering pump suction is not normal
Q:What is an industrial water pump?
The pump has the different uses, conveying different liquid medium, different flow rate, different lift range, therefore, its structure of course is not the same, the material is different, in general, can be divided into:1, urban water supply 2, sewage system 3, civil and construction systems 4, agricultural water conservancy system 5, power station system6. Chemical system 7, petroleum industry system 8, mine metallurgy system 9, light industry system 10, ship system
Q:The distance from the pump button to the ground
After confirming that the fire pump has started running, issue a command signal to the hydrant button to light the green answer light.
Q:Fire pump control cabinet There are 6 pumps, two indoor fire hydrant pumps, two spray pumps, and two outdoor pumps
You said the three line refers to the control room, the control cabinet, the main pump directly start the straight line of water pump. Each pump should be equipped with single straight line Kai, reported that the cabinet Jinglian dynamic multi line linkage control board has three buttons corresponding to a remote spray pump, fire hydrant pump, pump start outdoor fire hydrant. This requires three straight lines, from the cabinet to the three pump control cabinet, which is the 9 line you call. The water pump control cabinet is provided with a terminal for supplying a remote pump. By looking at the wiring diagram of the water pump control box, you can find the technical personnel of the control cabinet manufacturer if you can't find them.
Q:What is the displacement of the pump? Flow? What is the volume efficiency and mechanical efficiency of the pump?
Displacement of a pump: the volume of the discharged liquid calculated by the change in the size of the sealing geometry for each revolution of the hydraulic pump
Q:What are the parts of a pump? How do you classify it?I just want to know
The liquid ring pump: pumping air, the working medium is generally at room temperature water gas lift pump: simple structure of submersible sewage pump: a form of basic principle, performance parameters of centrifugal pump, with it the same. Underwater installation, sound, water cooling condition, screw pump: spiral lower invasion water medium variety formThere are too many kinds of pumps, such as submersible pumps for wells, centrifugal feed pumps, sewage pumps, etc. the submersible pumps are wet, oil immersed, etc.The water pump for automobiles is divided into oil lubrication and grease lubrication,
Q:What is the minimum continuous flow of a pump?
Quality solutionsMinimum flow of pump, minimum continuous flow of pumpIn order to ensure the proper use of the pump and the normal operation of the pump manufacturer will indicate the minimum pump in the sample of the continuous operation flow, the correct selection or use to warn or instruct users. According to the provisions of the API standard, the minimum continuous flow into the minimum continuous stable flow and continuous flow. Most small thermal limit(1) the minimum continuous stable flow.API standard specifies the minimum continuous stable flow refers to the vibration limit does not exceed the standard set by the pump can work normally. The minimum flow pump at small flow rate, there will be noise and vibration increase, API of this provision is to ensure that the service life of the pump, avoid due to improper operation of the pump caused by the adverse effects.
Q:If you use an ordinary 15W submersible pump, put it in the tank, if the leakage, the fish will hang it?
What will happen then? The aquarium glass is an insulator. The water in the fish tank has the same potential as the live wire, and the fish is like a bird standing on the fire line. No electricity flows through their bodies, so they won't get electrocuted. But if you put your hands into the water, you will get an electric shock, because the line voltage through the water, then your body and the earth to form a loop, current flowing through your body you will get (of course, if you stand on the insulator does not get an electric shock)
Q:What is the principle of a turbopump?
The working conditions of the turbine are different from those of the medium used, so the structure of the turbine is varied, but the basic working principle is similar. The most important component of a turbine is a rotating element (rotor or impeller) mounted on a turbine shaft with blades uniformly arranged along the circumference. The energy of the fluid is converted into kinetic energy in the flow through the nozzle, and when the fluid passes through the rotor, the fluid impacts the blade and drives the rotor to rotate, thus driving the turbine shaft to rotate. The turbine shaft drives the other machinery directly or through the transmission mechanism, and outputs mechanical work.
