Product Description:

Production Introduction:
JET series pumps have the advtanges and characteristic of self-priming pumps and centrifugal pumps. Water jet elements realize self-priming function.Pumps by the optimized design, have the advantages of bigger suction, high head, smooth operation, and reliable performance, which is the ideal tool for agriculture, and household, etc

Application:
This series pump is a new type of ideal economical household pump, and widely used in pumping water from well, increasing water pressure, garden irrigation, water supply for vegetable green houses, industrial mining enterprises and aquatic breeding fields 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.0.10% by volume and granular size should be max.0.20mm.
2.Medium temperature shouldn’t be over 40℃and PH should be6.5-8.5.
3.Power frequency should be 50Hz,single phase voltage 220V, and voltage fluctuation should be 0.9-1.1 times than the rated.

Q:Advantages and disadvantages of canned pumps
The graphite bearing lubrication medium, make the operation less noise and manual, reduce maintenance costs; in recent years, bearing material added with silicon carbide SIC, super hard, life is better than that of graphite bearing.The vertical structure can be installed on the pipeline like a valve, the installation is convenient and quick, and the motor and the impeller can be drawn out only when the utility model is used, and the pipeline is not needed to be removed.The utility model can be installed and run with a shock absorber or a damping pad, so that the pump is less noisy at running time.
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:Constant pressure pump working principle
Constant pressure pump is pressure maintained at the set pressure, flow control valve according to the order, there is pressure to set, after the pump displacement is reduced, as for how to reduce emissions, to see how much you need to flow.
Q:What is the difference between centrifugal pump and rotary vane pump?
Directly said vane pump on the line, generally do not say rotary vane pump.The centrifugal pump is divided according to the direction of the liquid flow in the impeller
Q:How many kinds of pumps are available and the operating principles of various pumps?
There are many kinds. See what divides.According to the working principle can be divided into: the power type pump, also called pump or impeller vane pump, depending on the dynamic effect of the rotation of the impeller on the liquid, the continuous energy transfer to the liquid, the liquid kinetic energy (mainly) and the pressure will increase, then converting kinetic energy into pressure energy through the discharge chamber, and can be divided into centrifugal pump, axial flow pump, partial flow pump and vortex pump etc..
Q:What is a positive displacement pump? He Weizheng displacement?
And includes a pump chamber (24) to open and a channel is arranged between the entrance and the pump chamber (26) in the second one-way valve (15), and one for the continuous displacement member (13) in the pump shell (10) in the travel section (S) actuating mechanism reciprocating motion.
Q:Suction stroke and lift of water pump
Lift pump lift pump can lift refers to the height, usually expressed in H, the unit is m. centrifugal pump lift to the impeller center line, divided by two parts. The vertical height from the pump impeller centerline to the water surface, the water pump to suck water up to the height, called water head, referred to as suction pump impeller; from the center line to the vertical height of the water tank, the water pump can put pressure on the height, called water pressure head, referred to as the pressure. The pump head = + suction head pressure water head should be pointed out that the nameplate marked head refers to the pump itself can produce lift, it is not with the pipe flow friction resistance caused by the loss of lift. In the selection of water pump, attention can not be ignored. Otherwise, will be pumping Sheung Shui.
Q:What should be used to pay attention to the use of mechanical pumps?
There are many kinds of pumps, such as centrifugal pumps, piston pumps, diaphragm pumps, vane pumps, gear pumps, etc.
Q:The function of centrifugal pump
6. Stuffing box mainly consists of packing, water seal ring, stuffing box, packing gland and water seal pipe. The function of the stuffing box is mainly to close the gap between the pump shell and the pump shaft. The water in the pump is not allowed to flow outside and the outside air is not allowed to enter the pump. Always keep the vacuum in the pump! When the pump shaft and packing friction heat, it is necessary to rely on water seal to control water into the water ring, so that the filler cooling! Keep the pump running properly. Therefore, in the water pump running inspection process, the stuffing box inspection is to pay special attention to! In the operation of about 600 hours, it is necessary to replace the packing.
Q:What kind of motor does the hydraulic pump need?
Calculation of actual oil pump power:First count the flow: Q=dn L / minD displacement / revN RPM / minThen calculate the actual power: N=QP/ (60K) kwQ flow L / minP MPa MPaK total efficiency (usually 0.85)I do not know what the landlord said, 2.5L is the displacement or flow at the end, the concept must not be confused
