Q:Pump operator's responsibility Sharing the rules, responsibilities, etc..
3. master the operating rules of the pump operation, and make sure the pump position is reasonably determined. Do a good job of site investigation, find out, pay attention to.4. master the working principle and basic technical parameters of the delivery pump. Obey the command of production dispatcher to ensure the completion of production tasks.5., according to the number of tanker at the scene, determine the pumping speed, in order to ensure the continuity of pouring.6. normal pumping, the discharge rate should be uniform, to prevent uneven discharge, resulting in pressure pipe gas plug, and thus lead to pipe or pipe explosion accident.
Q:What is the difference between centrifugal pump and positive displacement pump?
The centrifugal pump is usually driven by an impeller, and the head has a functional relationship with the flow rate. Positive displacement pump is gear or piston drive, each stroke output flow is constant, and the head does not matter, the pressure head can be infinite.
Q:How about the depreciation of vacuum pumps?
(three) appliances, tools, furniture and so on related to the production and operation activities, for 5 years;(four) aircraft, trains, ships and other means of transport for 4 years;
Q:Water pump does not produce water, what are the reasons?
The reason why centrifugal pump does not produce water:1. pump inlet or sink, water tank water shortage.2. water pump pipe blocked or valve not open.
Q:Why is the flow of the pump too small will occur cavitation phenomenon?
Why is it easy to produce cavitation when the inlet flow of pump is lowered?This is because the main performance parameters such as the head, power and efficiency of the centrifugal pump are not fixed, but vary with the flow rate. The curve drawn on a coordinate paper is called the performance curve or characteristic curve of the centrifugal pump. What happens when the flow rate decreases? The disadvantage of throttling adjustment is that the pump flow is small, and the impeller is easy to cause cavitation
Q:Roots pump and dry pumpRecently, the work involved in the vacuum pump, do not understand this, is a ads602 vacuum pump
The front stage pump to a certain pressure to start the roots pump, roots pump has advantages of is at the entrance of low pressure gas pumping speed is high, popular point is in high vacuum pumping speed is still relatively large. With the former pump can achieve different limit the vacuum is different.
Q:Water pump outlet valve sequence
Design specifications detailed manual instructions, divided into two cases:1, pump water first check valve, suitable for small caliber pipeline, gate valve to protect the non-return valve, not damage function;2, pump water out of the first gate valve, check valve for large diameter pipe, at this point valve easy to open and close;The setting of the check valve is mainly to avoid the high reverse speed of the pump and the condition of the submerged pump house. Set in the suction port of the pump, then stop the pump water flow will still affect the pump. In addition, the pump suction should try to avoid installing too many pipe fittings, so that the pump can maintain sufficient cavitation margin.
Q:What are the differences between the sewage pump and the clean water pump?
2. in order to prevent the wound, water pump impeller design is more simple but not ring pump, equipped with tips, cloth and other debris can be crushed after the pump, and the impeller water pump is relatively complex, but the efficiency will be significantly higher than the former.Why can't the sewage water pump and impeller: because features of key design, resulting in water pump for sewage situation is likely to occur, blocking, winding, wear and corrosion occurs, resulting in damage to pump or scrapped, so water pump can not be used for sewage.
Q:How to adjust the flow of piston pump?
Changing the size of the current in the solenoid valve can change the angle of the tilting element, and then change the stroke length of the plunger in the pump cylinder, that is to say, to change the flow of the pump. An inclined angle is called a quantitative pump, and the angle of inclination can be changed, which is called a variable pump.
Q:What is the dry running protector of screw pump? What's the principle and function? Thank you
Principles are generally temperature sensing, such as: when the screw pump by air, the stator and rotor will be heated due to friction,
