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.

Application:
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: Know flow and lift how to calculate the pump power?: The pump power (kw) ={9.61* flow (cubic meters per second) * head (m)}/.Where ETA is device efficiency, including mechanical, electrical loss and other factors, generally between 55%~80%. The smaller the pump, the lower the efficiency.

Q: A residential building with a floor height of 11 stories and a roof height of 33 meters. The height of the water tank is 37.7 meters. The basement is -3.3 meters, only set fire hydrant, fire pump only consider the indoor fire water, fire flow should be 10l/s. Now select a fire pump, concrete should be much traffic, big head, flow determine how? How to determine the head, I hope to say some more detailed, thank you, and there is to explain this question, why is the fire pump lift 120?. Thank you: According to the water quantity form fire flow water supply system fire safety in high-rise building fire hydrant pump lift is 10L/s, accurate algorithm is to say after a simple calculation with each indoor hydrant flow is two 5L/s bolt so to get the most unfavorable point for the calculation unit to calculate the minimum requirements, with the most unfavorable point suppository pressure specifications 0.07MPa, partial loss of the most unfavorable line and the line (according to the equivalent length) and loss (according to the material resistance coefficient), and finally the pump head loss of gravity difference. But we just calculate the construction elevation difference multiplied by 110% to 120% to determine the head {there is a need to know is: conversion head (m), (kg) and MPa kg 1MPa=10 kg = 100m is the vertical water column on unit area pressure conversion

Q: How can the submersible pump level meter be connected?: Install liquid level controller, two position liquid level sensor, controller to buy manual, wiring according to wiring diagram.

Q: What is the principle of a turbopump?: Turbine [turbine] is a machine that converts the energy contained in a fluid medium into mechanical work, also called a turbine. Turbine is the transliteration of English turbine, derived from the Latin word "turbo", meaning "rotating object".

Q: Why should I pump the pump before starting the centrifugal pump?: 1., if it is backward flow, it is not pumping;2., if the pump is installed underwater (such as submersible sewage pump), it is not pumping;3. pump is for installation in the form of suction. If no diversion irrigation pump, then the pump is full of air quality, air density is less than water, the pump will not be inside the gas out, the pump pressure will not be far less than the atmospheric pressure, the water will not be pressed into the pump to pump through irrigation formed inside the closed environment, the pump will start water out will cause local vacuum, entrance external water pressure into the pump is in inside and outside differential pressure, complete water movement. (vacuum water diversion is directly through the vacuum pump pumping the air in the pump, resulting in internal and external pressure difference, the external water pressure in the internal and external pressure is press into the inlet of the pump. The principle is the same as the pump. A standard atmosphere of =10m water column.)

Q: What are the main performance parameters of hydraulic pumps?: speedOperating speed is the actual rotation speed of a pump (or motor) at work.Rated speed is the maximum speed that can operate normally for a long time under rated pressure. If the pump exceeds the rated speed, the work will cause insufficient oil absorption, vibration and noise, the parts will suffer cavitation damage, life expectancy.Minimum steady speed is the minimum speed allowed for normal motor operation. At this speed, the motor does not appear crawling phenomenon.

Q: How can I buy a pump?: 3 、 mechanical requirements of high reliability, low noise, vibration.4, the correct calculation of pump procurement costs, the pump manufacturer to inspect, requiring good quality equipment, good after-sales service, spare parts can be timely supply.The micro pump and the motive of the mechanical energy or other external energy transmitted to the liquid, the liquid energy increase, mainly used to transport liquids including water, oil, alkali liquid, emulsion, suspension emulsion and liquid metal, but also transport liquid, gas mixtures and liquids containing suspended solids.The technical parameters of pump performance include flow, suction, lift, shaft power, water power, efficiency and so on.

Q: What are the problems that should be paid attention to when using vacuum pumps?: (8) in the process of running the pump, the bearing temperature shall not exceed the ambient temperature 35C, and the maximum temperature shall not exceed 80C.(9) if the abnormal sound of the vacuum pump is found, the reason should be stopped immediately.(10) vacuum pump to stop using, first shut down valve, pressure gauge, and then stop the motor. (11) vacuum pump in the first month of work, 100 hours after the replacement of lubricating oil, oil every 500 hours after the change.(12) adjust packing gland regularly to ensure the normal condition of drip in packing room. (13) regular inspection of shaft sleeve wear, larger wear should be replaced in good time.

Q: Types and differences of pumps: Depending on the flow of the fluid, they can be subdivided into the following:Classified centrifugal axial flow type mixed flow tubular flow typeThe basic principle of impeller centrifugal force generated by the high-speed rotation of the fluid energy rotary vane extrusion propulsion of the fluid increases the pressure to get the energy mix and energy principle of centrifugal and axial and centrifugalSuch as: central air conditioning centrifugal fan, central air conditioning or cold storage axial flow water pump, mixed flow water pump, domestic air conditioner, indoor fanWorking principle of pump and fanI. the working principle of centrifugal pumps and fansThe centrifugal force generated by the high-speed rotation of the impeller fluid power, namely fluid through the impeller, pressure and kinetic energy can be improved, which can be transported to the height or distance. The impeller is arranged in a spiral shell, when the impeller rotates, the fluid axial inflow, and then turn 90 degrees into the impeller and the radial outflow impeller. Continuous rotation of the impeller inlet in the form of vacuum, so that the fluid continuously by the pump suction and discharge.

Q: No negative pressure water supply equipment, both the main pump and auxiliary pump, power is not the same, how to choose the control cabinet?: 1) microcomputer frequency conversion control cabinet2) water pump unit3) current stabilizing compensator4) vacuum suppressor5) all kinds of pipe fittings, valves and so on
