Q:What are the ways of hydraulic pumps?
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.
Q:How to select hydraulic pump?
1. rpmOperating speed is the actual rotation speed of a pump (or motor) at work.Rated speed is the maximum speed that can operate normally for a long time under rated pressure. If the pump exceeds the rated speed, the work will cause insufficient oil absorption, vibration and noise, the parts will suffer cavitation damage, life expectancy.Minimum steady speed is the minimum speed allowed for normal motor operation. At this speed, the motor does not appear crawling phenomenon.
Q:What is a feed pump?
In general, high lift pumps are required with a front pump (which is similar to the feed pump of the landlord) or a low position;
Q:What is the relationship between the minimum suction vacuum of a pump and the required cavitation?
Suction is allowed to pump the vacuum from the distance from the inlet, which is part of the field installation.The manufacturer of cavitation allowance is closely related to the design and process of pump. Estimation formula: cavitation allowance =10.33 meters - allow suction of -0.5 meters (safety).
Q:Why does the centrifugal pump start with a closed valve and the axial pump starts with an opening valve?
Centrifugal pumps require a vacuum to produce negative pressure, which allows atmospheric pressure to lift the water surfaceAxial flow pump impeller is thrust on water
Q:No negative pressure water supply equipment, both the main pump and auxiliary pump, power is not the same
Non negative pressure water supply equipment can be divided into non negative pressure tank and box type non negative pressure compensation device, steady flow tank type non negative pressure water supply equipment is the negative pressure tank, pressure tank can eliminate the negative effect of network equipment, is equipped with a vacuum suppressor and water protection box; non negative pressure water supply equipment has the advantages of simple device is a water tank with the boost voltage stabilizing device of complex box at the same time with no negative pressure tank.The tank type non negative pressure water supply equipment adopts vertical multistage centrifugal pump. This kind of pump is low noise and high efficiency. Such as CDL series and imported CR seriesOrdinary box type non negative pressure water supply equipment can use multi-stage centrifugal pump, also can use stainless steel submersible pump, submersible pump costs will be lower, but the maintenance costs will be high.
Q:What is the pump delivery? What's the difference between years and years?
Secondly, the landlord asked the question, although I did not go to the insurance company to practice the operation, but to my four years of learning, as well as internship experience, or can help you analyze, and I hope to help you.Pay is a one-time payment of premium -- all wholesale D sea n
Q:How to distinguish the flow and displacement in the hydraulic pump? What's the difference between the two?
For example, once you sprinkle water from the tank to the ground, one shot of water is 1000 milliliters, which is equivalent to displacement, once (pump turn) 1000 ml.,
Q:Constant pressure pump working principle
The pressure loss is borne by the valve. Constant pressure pumps generally do not export direct load, unless you need this load response is very fast, then the maximum displacement of the pump work, so as to ensure the rapid response of the load.
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.
