Product Description:

Product introduction:
QDX. QX series submersible 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 three phase is at the upper pa" of pump and seal is used where pump and motor combine, which is a kind of double end mechanical seal "O " rings are applied to all static joints. Floator switch can be equipped to control pump" starting and stopping automatically according to the water level.

This series pump is small and light, which is widely used in countryside for elevating water from well, irrigation, sprinkling and domestic water supply, and also used in draining off water for fishpond and building site.

Work Conditions:
The pump can work properly and continuouslyunder following operational conditions:
1 .Medium is not corrosive, Sand contents shouldbe max. 0.10% by volume and granular sizeshould be max.0.2mm.
2.Medium temperature shouldn’t be over 40℃ and PH should be6.5-8.5.
3.The pumps should be operated within rated head.
4.The pumps should be fully submerged into water with depth of less than 3m mad max. the pump should be min.0.5m over the water bottom and not be inserted into sludge.
5.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 are the important parameters of the pump?
Mass flow is expressed in Qm units: t/h, kg/s, etc.The relation between mass flow and volume flow is:Qm= P QIn the p - type liquid density (kg/m3, t/m3), room temperature water P =1000kg/m3.Lift H
Q:Types and differences of pumps
(I) volumetric typeClassification reciprocating rotary typeThe basic principle of reciprocating action by the piston in the cylinder in the cylinder volume changes again, with the suction and discharge of fluid in the shell or the rotor rotating member rotates, the volume of work between rotor and casing changes to the suction and discharge fluid, such as piston pump gear pump, screw pump(two) blade type;The main structure of vane pumps and fans is rotary, bladed impellers and stationary housings that rotate fluid through the impeller to do work, thereby enabling fluids to obtain energy
Q:What is a vacuum pump for?
In fact, the vacuum pump and high Swiss fan, high Swiss high-pressure blower, high Rui high-pressure pump principle is almost the same
Q:How much water does the water ring vacuum pump run for an hour? If there is no steam separator, does the water vaporize?
For example: water storage is relatively small, it needs to reduce the temperature of the heat exchanger. If the tank is relatively large, it does not need cooling water circulation pump again when the temperature is very low, there is no need to heat exchanger. So you need to ask how much water this is not OK.In a soda separator problem:
Q:What kind of motor does the hydraulic pump need?
The motor should be determined according to the work environment, such as 220V.12V.24V.72V or 380V, and then the power.Calculation of actual oil pump power:
Q:Household automatic booster pump, how much pressure can you work automatically?
With the pressure does not matter, because the pressure is small, it is necessary to boost the pump, the water pressure with the pipe flow and the size of the booster pump related
Q:How many pumps does the 80cm tank use?
For example, you are 80 cm tank, assuming you are 40 cm wide, the water surface is also 40 cm, then the final count by 80X40X40=128000 cubic centimeter, that is, 128000 ml.
Q:The difference between diaphragm pumps, vacuum pumps and centrifugal pumps
The diaphragm pump and centrifugal pump refer to the structure of the pump, and the vacuum pump means the use of the pump. There is no comparability between them.Centrifugal is the sign of inertia of an object. As the umbrella turns, water droplets move out of the outer edge of the umbrella and are thrown out. This is what is called centrifugal. Centrifugal pump is designed according to this principle. The high speed rotating impeller blade drives the medium to rotate and is thrown out so as to achieve the purpose of conveying.
Q:Know flow and lift how to calculate the pump power?
N=Q.H.g. P / nN - motor power, kWH - pump head, MQ - pump flow, m^3/sG - gravity acceleration g=9.81
Q:Why is the sewage pump device coupler?
Advantages of installation and arrangement of sewage pump coupling:1. automatic coupling device, easy installation and maintenance. In the absence of automatic coupling device under the condition of fixed installation, such as pump fault maintenance personnel need to unscrew the screw pump lifting water, repair, or other small pump to pump the water down perfect maintenance, if the water is dirty, it would be difficult for people to go to the next, then the overhaul had great difficulty.
