high quality refrigerating machine gear oil pump LB series
Refrigerator gear pump Application
1.be as transfer pump
2.be as booster pump
3.be as fuel pump
4.be as injection pump
5.be as hydraulic pump
6.be as lubricating pump
7.special use refrigerator pump
It is used intransferring N32 of N46refrigerated lubricating and other lubricant oil of ammonia machine or from machine.The suited temperature is 10-800C
LB refrigerating machine gear pump adopts the internationally advanced level in the eighty s the new technology of a pair of circular arc tooth sine curve type.
It is compared with the involute gear, the most prominent advantage is in the process of the gear and tooth profile surface no relative sliding, the tooth surfaces without wear, balanced operation, no trapped fluid phenomenon, low noise, long life and high efficiency.
The pump out of the bondage of traditional design, making the gear pump on the use of the design, the production has entered a new field
Suction and Extrude Port Diameter(mm)
Max Differential Pressure(Mpa)
Note:Pumps above can be matched with different motor as customer's requirement.

Q:Harm of air pump and pump
Minimum starting current when centrifugal pump of such a small impact on the grid but long closed operation will make the liquid in the pump to the pump overheating temperature is too high will lead to the problem of the seal to a certain temperature will cause deterioration of oil bearing bearing caused by excessive wear and even bite dead
Q:Attention should be paid to the use of pumps?
1, pump shaft packing completely worn, it is necessary to add in time, if you continue to use the water pump will leak. The direct effect of this is the increased energy consumption of the motor, which will damage the impeller. 2, the use of pumps in the course of a strong vibration, then must stop to check the reasons, or the same will cause damage to the water pump. 3 gear pump valve Water Leakage, some will use the soil into the water pump inlet tube, the water washed in the end valve, this is indeed undesirable. Because when the dry soil into the inlet pipe, when the pump started working, these dry soil will enter the pump, which will damage the pump impeller and bearings, which shorten the service life of the pump. When the valve Water Leakage must take to repair, if it is serious that it is necessary to replace the new. 4 after the use of pumps must pay attention to maintenance, for example, when the pump is exhausted, we should put the water pump who put clean, it is best to remove the water pipe, and then rinse with water. 5 water pump on the tape should also be written down, and then always flush, and then light out to dry, do not put the tape in the dark damp place. Water pump tape must not be stained with oil, not to tape coated with some sticky things.
Q:Variable flow pumps are variable pumps
Yes. The variable pump is designed to change the flow rate
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:The working principle of magnetic pump
Structure characteristics1. permanent magnetPermanent magnet operating temperature range is made of rare earth permanent magnet wide (-45 - 400 DEG C), high coercivity, magnetic anisotropy direction is very good, also won't happen in the same demagnetization phenomenon when is close, is a good source of the magnetic field.2. isolation sleeveIn the metal isolation, isolation sets in a sinusoidal alternating magnetic field, in a cross section perpendicular to the direction of magnetic field lines induced eddy current and converted into heat. Eddy current expression is:. The Pe - K constant; eddy current; rated speed of N - T - pump; magnetic drive torque; F - the pressure inside the sleeve; D sleeve diameter; a material resistivity; and the tensile strength. When the pump design is completed, N, T is the given conditions, to reduce eddy current only from F, D, and so on. Non metallic materials with high resistivity and high strength production isolation, in reducing the eddy current effect is very obvious.

Q:Metering pumps related matters
2) change the metering pump diaphragmTrouble is often encountered when the old diaphragm is removed. Provide some additional advice on how to remove the old diaphragm.After in the pump head loose, remove the pump head before the stroke length adjustment to the 10% position. To ensure that the electromagnetic axis has sufficient pressure to maintain its connection firmly, so that you can unscrew the diaphragm.The pull end torque from the Jack out of the screw. Seize the liquid counter clockwise rotation. There is a slight resistance that can unscrew the diaphragm.Chemical 3 measurement may end in fluid crystallization, resulting in a one-way valve ball and seat valve does not work.In the end inhalation metering pump may have a gas leak. Hydraulic end suction side connector may lack O ring or suction valve connection loose.3) flow monitoring and measurement of a high viscosity medium, in the process of liquid delivery received a flow failure signal, how can we solve this problem?Move the hydraulic end by loosening the 4 pump head screws. Rotating stroke length to 10%, and seize the hydraulic end, and then slide out of the screw hole, then the screws do not touch them, but still control the back and diaphragm. Then rotate the component counter clockwise, with a slight resistance, and the diaphragm will loosen from the electromagnetic axis. If the diaphragm is not loose, use some grease on the contact surfaces of the diaphragm and the electromagnetic shaft. After a few minutes, gently tap the diaphragm with a small plastic hammer. Then proceed again in accordance with the above description.
Q:How to calculate the motor power of metering pump?
Two Hydraulic power, metering pump rated flow (L/H) X, maximum pressure (Barg) / 36000 = kw
Q:60 type concrete pump performance?
HBT60.13.90S performance parametersParameter name unit HBT60.13.90SMaximum theoretical concrete conveying capacity m3/h 69/43Maximum pump outlet pressure Mpa 13/7
Q:Fire pump and shower pump flow head selection, high resolution.
3, larger than 25000, the minimum water consumption of indoor fire hydrant is 20L/s4, the minimum water consumption is the flow of a fire hydrant.
