Boton high quality refrigerating machine gear oil pump LB series

Structure

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

Q:What is a positive displacement pump? He Weizheng displacement?
The principle and structure of positive displacement pumps are similar to those of hydraulic motors. Positive displacement is the pump outward to provide flow and pressure, that is, conventional pumps. A negative displacement pump is a hydraulic motor that rotates by external pressure and flow.
Q:What does "dual purpose" of water pump mean? Please expert advice
In order to ensure safe and continuous operation, three pumps usually need two units and run one standby.Precautions for using pumps1, if there is any small water pump failure, remember not to work. If the pump shaft packing end wear should be added 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.
Q:Working principle and diagram of axial piston pump with pressure compensation variable
The size of the outlet flow pressure compensated variable displacement pump with outlet pressure of approximately in a certain range according to the constant power curve. When the pressure oil from the main part of the channel (a), (b), (c) into the inferior vena cava (d) variable shell, oil by the channel (E) respectively into the channel (f) and (H), when the spring force is greater than the oil (f) into the lower end of the piston ring servo hydraulic thrust area when the oil liquid (H) to the chamber (g), push the variable downward movement of the piston, the pump flow increases. As for the hydraulic servo piston end thrust force ring shaped area is greater than the spring when the servo piston moves upward, blocking channels (H), the (g) (I) through the cavity of the oil cavity pressure relief, at this time, the piston moves up, the variable head angle decreases, the pump flow rate decreases.
Q:Direct connection pump What is straight pump and non direct pump? What's the difference in structure?
Direct connected pump: pump impeller installed directly on the motor shaft, it looks like a whole, relatively compact, simple installation, but the general power is relatively small (big bad processing connection, but not absolute);Non direct pump: pumps and motors are independent of each other, through the coupling torque transmission, the structure is relatively large, complex installation, to adjust the level / concentricity and so on, the general power is relatively large
Q:Does the control cabinet of the fire control pump need to be related to the fire control room?
Automatic sprinkler, which is mostly used in this device or high water tank, the whole set of equipment must meet the most unfavorable point (the farthest the highest point of water) water pressure of the faucet.
Q:Common failure treatment of piston pump
x09x09 (3) no connecting key on pump shaft or motor shaft1) break2) missing x091) replace key2) patch keyx09x09 (4) pump internal slide vice stuck1) the clearance is too small2) parts accuracy is poor, assembly quality is poor, gear and shaft coaxial deviation is too large; plunger head clamping; blade perpendicularity difference; rotor pendulum difference is too big, rotor slot has wound or blade has scar, force after fracture and stuck
Q:How can I buy a pump?
Selection principle of pump:1, so that the selected pump type and performance parameters meet the unit flow, lift, pressure, temperature and other requirements, the most important thing is to determine the voltage, the maximum lift, and when the head high reached much traffic.
Q:Fire hydrant pump button, under what circumstances do not need to install?
General high voltage system, when normal, use small pump steady pressure.Fire hydrant button lifting pump is one of the multiple pumping methods, and it is an important link of reliable operation of the system.
Q:What are the advantages and disadvantages of the pump control system and valve control system in the hydraulic system?
Valve control system is generally used for open systems, through the proportional valve or servo valve flow changes to control the motor or cylinder actuator action. The advantages of the system are energy saving, heat generation, and control accuracy. The disadvantage is that the system is complex and the cost is higher.
Q:Because the water pressure of the booster pump is not enough, it can not work automatically. It can only be operated by hand. It is inconvenient to use.
If the water pressure is not enough, the pump can not start, then it must be wrong. Because if the water pressure is not enough, the pump should be running automatically. It's just because the water pressure is not enough.
