Product Description:

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

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:Is the flow meter in front of the pump or after the pump?
Agree upstairs. Pump should be straight before the paragraph, 15 times the nominal length of the caliber.
Q:What is the relationship between the minimum suction vacuum of a pump and the required cavitation?
When the vacuum pressure is called vaporization pressure, cavitation is more than the surplus energy of vaporization pressure at the unit weight of the liquid in the pump suction port of the unit, with mark. The absorption process is to NPSH delta H: pump suction fluid allows the vacuum pump installation height is the unit of rice.
Q:Is the diaphragm pump and the drain pump one?
Therefore, the need to play a liquid discharge pump, if the medium is corrosive liquid, high viscosity, volatile, flammable, highly toxic liquid, you can choose diaphragm pump. Conversely, the general liquid, there is no special requirements, you can use the general centrifugal pump to reduce costs.
Q:How about the depreciation of vacuum pumps?
(five) electronic equipment, for 3 years.The depreciation period of a vacuum pump can be calculated for 5 years. The expected residual rate is generally 5%, or it can be estimated by itself.
Q:What is the difference between swashplate pump and crankshaft pump?
Piston pump: valve plate, valve plate, piston, piston ring, crankshaft, connecting rod and so on, all belong to its spare parts.Piston pump working principle: by the piston in the pump cylinder for reciprocating movement to suction and remove liquid.
Q:Variable flow pumps are variable pumps
To be exact, variable pump means variable displacement. Because if the displacement does not change
Q:Is vane pump good or gear pump good?
The main parts of a gear pump are gears that mesh with each other. The meshing driving gear and the driven gear are respectively arranged on two parallel rotating shafts. Because the gear teeth enter and exit the meshes, the volume of the teeth is changed, and the suction and discharge effect is formed.
Q:Why can't the centrifugal pump pump the vacuum?
Characteristic equation of centrifugal pumpStudy the effect of fluid on centrifugal pump to obtain energy.The experimental condition of u is that the ideal fluid of unit weight bends the flow between blades at infinity.U investigated the mechanical energy balance of the fluid between the adjacent two inlet and outlet sections, that is, the relationship between theoretical pressure head and theoretical flow.
Q:Why should I pump the pump before starting the centrifugal pump?
Before the operation of the centrifugal pump, the pump must be filled with water, exhaust the air, before you start the operation. All centrifugal pumps should be handled this way, which is the centrifugal pump itself.The way of water diversion:1., in the centrifugal pump outlet increase water diversion pump (usually using vacuum pump), start the centrifugal pump before, start the vacuum pump, the centrifugal pump air into;2. increase the vacuum water tank before the intake of the centrifugal pump to meet the working conditions of the centrifugal pump;3. in the centrifugal pump inlet water increase valve, to meet the working conditions of centrifugal pump;4., if the water tank or water tank volume of water level is higher than the centrifugal pump position, the first operation of the front row empty, usually do not empty, you can use.
Q:What is the difference between the ground pump and the pump in the commercial concrete?
What you should say here is the concrete pump.Ground pump: the pump will be placed in a position on the site, the pipeline will be sent to the construction of concrete surface,
