FAQ

The distance from the pump button to the ground

After confirming that the fire pump has started running, issue a command signal to the hydrant button to light the green answer light.

What is the main difference between SK water ring vacuum pump and 2BV water ring vacuum pump?

The 2BV vacuum pump belongs to the machine pump coaxial type direct connection design. It saves space and is easy to install;The use of mechanical seals as standard configuration eliminates leakage and easy maintenance;Smooth running, low noise to 62 decibels;

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.

What is the pump lift voltage? And how to suppress the pumping voltage rise?

The reverse voltage and torque electric torque instead, and the motor has strong braking torque, forcing the rotor quickly stopped, but usually AC-DC-AC converter is the main power AC/DC rectifier circuit is irreversible, and therefore can not return to the power grid, resulting in the main circuit of the capacitor voltage increases two that is called the pump voltage.

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?

Valve control system is generally used for open systems, through the proportional valve or servo valve flow changes to control the motor or cylinder actuator action. The advantages of the system are energy saving, heat generation, and control accuracy. The disadvantage is that the system is complex and the cost is higher.

How many pumps does the 80cm tank use?

Filter pump to select the water per hour can be filtered more than 3 times, I personally feel that this is almost enough. Of course, the more times the better, but also consider that if the pump is too large, the water inside the tank will be too large.128X3=384LThat is, the flow must be more than 384L/H of the water pump.You can buy a bigger pump, because the pump for a long time there will be some attenuation and domestic things in general to sign data, so it should be based on your actual situation to buy. Taobao on this category is about 20~40 yuan.

What does centrifugal pump mean horizontally?

In other words, pump casing and pump body along the horizontal center of the pump leaves into the upper and lower halves, so that when the pump leaves the pump cover open, you can pump and bearings as a whole pumping out. No need to remove the pipe. I don't know. Do you understand?.

Filter backwash pump for what use, what is the principle of work ah?

Regeneration of the filter medium is required to regain the filtration capacity of the medium. The regeneration process is mainly accomplished by the backwashing pump (the backwash pump is not a special pump, referring to the pump for the completion of the process). The working principle is through the cleaning liquid from the downstream of the filter into the backwash pump (alkali, acid and water), reverse flushing filter medium, cleaning liquid discharged from the upstream, this process can be attached to the dielectric surface and internal impurities washed away.
