Product Description:

1) Function and Feature:
This adcanced V(WQ)series,a branch of single-phase drainge pumps, will be your ideal drainage helper. The letter’V’which substitutes for the letters "WQ"indicates the distinct design of the filter and the broadness of the high efficient area. It can work safely and efficiently at high flux with the feature of Complete heads. The design is designed to a wide tunnel which helps to convey the long fiber liquid of the solid whose diameter Is about 15-35mm. The selection of bottom suction strcture, stainless steel and special and castiron make the pump has the capabilities of complete drain and high resistance of abrasion and corrosion. The float switch can automatically control on and off with the change of the liquor lever. The protector in the motor can automatically cut off the power when it overheated or overcurrented. Thus guarantee the security and

2) Work Conditions:
1.The maximum deep it is allowed in water is 5m from its center of impeller;
2.The trans mediums temperature shouldn t higher than 40℃
3.The trans medium’s FH scope is from 4~10
4-Thc kinematics viscosity of the trans medium is from7x10~7x10~5.The maximum density of the tr^ns medium is 1.2x10³kg/m³

Q:No negative pressure water supply equipment, both the main pump and auxiliary pump, power is not the same
Non negative pressure variable frequency water supply means no negative pressure superposed water supply equipment. When running, it is connected directly to the water supply pipe. Always test the pressure of tap water pipe network and water supply pipe network pressure control system, when the water pressure is lower than the pressure required by the user, the frequency conversion device based on water automatically control the pump speed through the steady flow compensator of water balance, maintain a constant pressure water supply. In the multi pump system, the control system can automatically dispatch the water pump according to the water consumption. It can balance the working time of the pump and ensure the pressure of the water supply. When the water supply pressure satisfy the required pressure, the system automatically stops the pump by the external water supply pipe network directly. CJWFG-DYG non negative pressure superposed water supply system:
Q:Hydraulic pump displacement refers to the pump shaft what?
You can see the sign of your hydraulic pump. There will be a displacement **ml/r in the sign of the hydraulic pump (r stands for every turn, ML is milliliter)
Q:What are the meanings of the vacuum pump, the front pump and the main pump?
The main pump and the front pump with the general vacuum unitThe front pump can be understood as a mechanical pump. It can be used by itself, but the pumping rate or the vacuum can not meet the requirements. In this case, we add a booster pump
Q:What is the Rhodes pump?
Best answerRoots vacuum pump (referred to as: Roots pump) refers to the pump is equipped with two opposite direction of synchronous rotation of the leaf rotor, rotor, rotor and pump housing between the walls of a small gap and no contact with a variable capacity vacuum pump.Roots vacuum pumps have been tested for long time in the fields of petroleum, chemical, plastic, pesticide, steam turbine rotor dynamic balance and aerospace simulation, so it should be popularized and applied in china. It is also widely used in petroleum, chemical, metallurgical, textile and other industries. Vacuum pump fittings are used for noise control of vacuum pumps, vacuum pump silencers.
Q:The suction pump has a nominal suction range of 30 metersHow deep can a well be sucked?Well, sixteen meters,
That is impossible. The suction height of the pump is caused by the centrifugal force of the vacuum. The water is sucked into the vacuum
Q:Advantages and disadvantages of centrifugal pumps?
The uniform liquid no pulse phenomenon.(2) shortcomingsBefore running, the pump must be filled with liquid.For the supply of small flow, large pressure head inappropriate, inefficient and limited.Encountered imperfect design or operation is not at the time, such as milk, it is easy to produce foam, affecting the next process production.The installation is wrong. There will be "Qi tie" phenomenon.The efficiency is also lower than the reciprocating pump.The sources of knowledge are absolutely reliable!!!!
Q:Centrifugal pumps for normal operation, is it reasonable to install valves on their inlet lines?
Reasonable, no valve, how to debug, overhaulGenerally installed on imports of valves of relatively large Cv value
Q:What is the working pressure of the hydraulic pump in the hydraulic transmission system?
The operating pressure of the hydraulic system depends mainly on the load. Generally speaking, the working pressure of the hydraulic system means the highest working pressure of the system. If the pressure is higher than the value of the equipment, the relief valve works to relieve pressure. The actual working pressure of the hydraulic system is determined by the load, which refers to the actual pressure of the hydraulic oil and can be read directly from the pressure gauge. The pressure increases with the increase of the load. You Li's balance can know: the thrust of the cylinder = the load, the thrust of the cylinder = the working pressure of the hydraulic oil, the working area of the cylinder, the working pressure = the load / the area of the cylinder.
Q:How to adjust the flow of piston pump?
Changing the size of the current in the solenoid valve can change the angle of the tilting element, and then change the stroke length of the plunger in the pump cylinder, that is to say, to change the flow of the pump. An inclined angle is called a quantitative pump, and the angle of inclination can be changed, which is called a variable pump.
Q:How high can the pneumatic diaphragm pump be?
Diaphragm capacity, high temperature, pneumatic diaphragm pump ability, high temperatureMany users do not know how high the temperature resistant diaphragm pump, diaphragm pump either electric diaphragm pump or pneumatic diaphragm pump products it cannot do without diaphragm attachments, diaphragm materials mainly fluorine rubber, rubber, rubber, polyether road three EPDM, PTFE several, if not considering the gas temperature resistant diaphragm made of stainless steel. The temperature to 600 degrees of diaphragm pump diaphragm pump, but must use the diaphragm, so the diaphragm pump can Naiduo high temperature depends entirely on the diaphragm was affected by temperature, following to share various diaphragm pump diaphragm material and different material temperature choice diaphragm pump product right:
