Q:What is the lift of diaphragm pump?

Tell you: diaphragm pump head is liquid through the pump energy obtained is called lift it, and flow and pump speed, a liquid density is generally 1 kg is 10 meters lift, horizontal pipeline 10 meters 1 meters lift, a 90 degree bend is 1 meters.

Q:What is the pump delivery? What's the difference between years and years?

First of all, as a student majoring in insurance, I strongly condemn the first floor of ignoring practice and trampling on real knowledge!!The insurance industry criticized a lot, but it is required for many people, we should face and try to maintain the healthy development of the industry, the first floor of the insurance you have not done, have no contact with the insurance, insurance, not to dictate the nonsense, more should not be here misleading!

Q:There are second cutting, third cutting, why three times?

There are 2 situations, first, for example, a XXXX-160 type pump head 32, flow 100, motor 15kW, according to the model we need to cut a become head 28, flow rate of 88, this time, in addition to cutting the impeller, the pump or the original pump motor, became 11kW this is, re designed a new model, namely XXXX-160A, but most structural components did not change. In the same way, we want to design a XXXX-160B that makes the head 24 and the flow rate 80, then we just need to cut the impeller again and match the smaller (7.5kW) motor (the motor bracket needs to be redesigned). In general, multiple cutting impellers are designed to expand and enrich the model. Second, the actual use, if you think the flow head is too large, but also can be cut to make it smaller to adapt to practical applications. But the 2 and 3 cuts you ask are the first.

Q:The function of centrifugal pump

2, pump body, also known as pump shell, it is the main body of the pump. The utility model is provided with a supporting and fixing function and is connected with a bracket for mounting the bearing.3, the role of the pump shaft is to use the coupling and motor connected, the motor transfer distance to the impeller, so it is the transfer of mechanical energy of the main components.

Q:What kind of motor does the hydraulic pump need?

The motor should be determined according to the work environment, such as 220V.12V.24V.72V or 380V, and then the power.Calculation of actual oil pump power:

Q:What is the relationship between the minimum suction vacuum of a pump and the required cavitation?

When the vacuum pressure is called vaporization pressure, cavitation is more than the surplus energy of vaporization pressure at the unit weight of the liquid in the pump suction port of the unit, with mark. The absorption process is to NPSH delta H: pump suction fluid allows the vacuum pump installation height is the unit of rice.

Q:What is the cause of the damage of pump bearings?

In high-speed equipment, the most likely damage to bearings is high temperature.

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.

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:What is the liquid pump? What are their categories? What are their strengths and weaknesses?

The pump is constructed by connecting large diameter gas piston with small diameter hydraulic piston. The two piston area ratio produces a pressure ratio, and the maximum output pressure can be calculated by the pressure ratio. High pressure ratio produces high outlet pressure. You can set the outlet pressure through a simple gas pressure reducing valve. Pressure ratio * gas drive pressure = output pressure.
