Q:What is the nominal pressure of the hydraulic pump and hydraulic motor?: Rated flow refers to the flow under the rated speed and rated pressure input to the motor.Due to leakage loss, the actual flow of the input motor must be greater than its theoretical flow. Actual flow of motor (i.e. inlet flow) leakage flow = theoretical flow of the motor.

Q:Operating procedures for measuring pumps: First, preparation and inspection before starting1. Check to make sure that the drain line is equipped with a safety valve with the correct set pressure.2. Check the screws for the liquid end parts.

Q:What is the series of pumps? What is the difference between a unipolar and a multilevel? What is the meaning of each "first class"?: You're talking about a centrifugal pump. His series says the number of slices of the impeller (excluding the wheel, that is, the wheel)

Q:What are the reasons for sealing damage of centrifugal pumps?: The reasons for sealing damage of centrifugal pumps are as follows: six, the specific contents and handling methods are as follows:First, the centrifugal pump water quality is poor, containing particles.As a result of poor water quality, containing small particles and medium hydrochloride content is high, forming abrasive wear, centrifugal pump seal plane or pull the surface, resulting in groove, ring groove and so on.Treatment method: improve water pressure or medium, replace machine seal.

Q:Pump operator's responsibility 10Sharing the rules, responsibilities, etc..: 1., consciously abide by the traffic control department management rules, to achieve civilized driving, safe driving.2. responsible for the daily maintenance, cleaning and cleaning of the pump truck, and ensure the equipment is in good condition.

Q:What are the advantages and disadvantages of the pump control system and valve control system in the hydraulic system? How to choose in the project?: Pump control system is generally used for closed systems, the flow of the oil pump changes to control the motor or cylinder actuator action. The utility model has the advantages that the principle is simple, and the power of the engine can be fully utilized. The disadvantage is that the calorific value of larger, relatively poor precision.

Q:Why does the centrifugal pump start with a closed valve and the axial pump starts with an opening valve?: Because the characteristic curves of the two are different.The power of centrifugal pump decreases with the decrease of flow rate. When the flow rate is zero, the power is minimum, so the centrifugal pump is started with a closed valve.

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 is double hydraulic pump?: The 2 pumps are all coaxial connected together, driven by a motor, the general gear pump, piston pump

Q:What's the difference between non negative pressure and variable frequency water pump?: Re pressure to a given pressure pressure zone water supply, than frequency conversion water pump energy savingFrom a health perspective, a water tank variable frequency water pump, water tank and the atmosphere, easy occurrence of water pollution two, no negative pressure equipment without negative pressure tank and pump and valve fittings etc., no water tank, the whole process of water supply of water is completed in a closed system, with air contact to avoid two pollution problems water supply.From the management point of view, no negative pressure is fully automatic intelligent operation, reduce management costs, no water tank, reducing the trouble of tank cleaning. No negative pressure is the upgrading of variable frequency water pump products
