- Q: What is a gear pump for?
- Internal wear of oil pumpOil pump parts wear will cause leakage. The large leakage area between the floating axle sleeve and the end face of the gear is the main part of the inner leakage. This part of the leakage accounted for about 50%~70% of the total leakage. The pump efficiency of the gear pump is much lower than the input power when the gear pump is worn and leaked. All of its losses are converted to heat energy, which will lead to overheating of the oil pump. If the joint plane is pressed, the movement of the floating axle sleeve will cause a little wear and tear when the work is in use, so that the farm tools can be lifted slowly or can not be improved, so the floating axle sleeves must be replaced or repaired.
- Q: What is the dry running protector of screw pump? What's the principle and function? Thank you
- When the temperature reaches a certain value, the signal is transmitted to the electric control box through a dry running protector, and the electric control box is used to stop the screw pump so as to protect the screw pump.
- Q: What should I pay attention to when buying a pump?
- Four, packing inspection1. with the pump supply documents shall include: product certification, specification, packing list, agricultural pumps (such as submersible pumps, centrifugal pumps, mixed flow pumps, self-priming pump etc.) should be "Three Guarantees certificate", the implementation of the production permit (such as pump submersible pump, high pressure pump, high temperature pump 5 pump) we should have a production license.2. plugging of the orifice, to withstand wind and rain invasion, and should be strong, can withstand accidental damage.3. pumps and all supplied bulk parts supplied with the pump shall have the required identification number and shall be clear.4. pairs of oil lubricated bearings, bearings tank oil should be discharged, and fixed with "need oil filling" warning signs.
- Q: I would like to ask, constant pressure pump set pressure 20Mpa, the actual load is 15Mpa, then the constant pressure pump outlet pressure? If it is 20Mpa, then where is the loss of 5Mpa? If 15Mpa, the constant pressure pump 20Mpa how to understand? In addition, the constant pressure pump pressure is defined when the flow began to reduce the point, or a sharp drop in flow after the point?
- 15MPa. 20MPa means that if you enter the 20MPa, the variable mechanism will work, and the flow at this time automatically matches the load. 20MPa used to supply the fuel by maximum displacement.
- Q: Double floor sewage pump circuit diagram of a small problem
- Question 4 when you need backup, you need to switch the SA switch, but where you want it. For example, when the 1# pump is running and does not reach the high water level, the 2# pump will not operate. If SA is placed in the left position, 21 and 22 are connected, and the KT is electrically delayed, and the KAB action causes the 2# pump to function. After the KAB operation, the KT will be disconnected, restored to the ready state, and also convenient for KT to restart the power on time, and also avoid the time relay to work on a long-term basis.
- Q: What kind of motor does the hydraulic pump need?
- Hydraulic pump is a power component of hydraulic system. It is driven by an engine or an electric motor. It draws oil from the hydraulic tank to form a component of the pressure oil which is sent to the actuating element. Hydraulic pump according to the structure is divided into gear pumps, piston pumps, vane pumps and screw pumps.
- Q: Is the flow meter in front of the pump or after the pump?
- After the flowmeter is placed in the pump, it is better to add a pressure tank or a buffer tank, so that the flow meter will work better
- Q: What are the parts of a pump? How do you classify it?I just want to know
- According to the working principle can be divided into: centrifugal type and volume type centrifugal pump. By the centrifugal force of the impeller will accelerate the refrigerant, through to stay, so as to achieve the purpose of boosting; volume by changing the refrigerant in the flow volume to boost purpose.According to the media and installation conditions, water pump: centrifugal pump used: the impeller pump shaft, a curved blade on the impeller impeller outlet. The central entrance water vertically along the tangential direction of axial flow pump: high speed, large flow, low lift, mixed flow pump and centrifugal pump structure similar to that of the blade outlet angle is different, wide flow channel, close to the performance of axial flow pump displacement pump: safety valve must be opened before the start (metering pump, screw pump)
- Q: Hydraulic pump displacement refers to the pump shaft what?
- You can see the sign of your hydraulic pump. There will be a displacement **ml/r in the sign of the hydraulic pump (r stands for every turn, ML is milliliter)
- Q: How to calculate the motor power of metering pump?
- The total mechanical power and hydraulic power, divided by the overall efficiency of pump, and the pump head and the utilization rate of pump mechanical efficiency, and then multiplied by 1.1 times (API675), you can get a metering pump motor need more power.
