Q:What should be used to pay attention to the use of mechanical pumps?

Overall: large pump should first do a good job of the foundation, to find a good whole, fixed, and motor, pump should be added good oil, the first test of the motor, and then conjoined test

Q:Piston filling and peristaltic pump filling which precision is high?

First of all, we should know the working principle of each, and analyze the accuracy from the principle, this problem is very important. Piston filling, such as the injection of drugs that we have been ill, the accuracy of the piston pump depends on the accuracy of the motor and the area of the unit cross section

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,

Q:How many kilograms of water pump are there in the automatic washing machine on the market?

Longer service life. Automatic switch water pump, car wash automatically open and stop, easy to operate, not easy to bad, repair rate is low!!!

Q:What is a solution pump?

(4) smooth running, low noise, no lubrication, no lubrication and low noise due to the absence of rolling bearings and motor fans(5) a wide range of use, the high temperature, high pressure, low temperature, high melting point and other conditions are able to meet the requirements2.2 shielding pump shortcomings(1) because the shielding pump adopts sliding bearings and is lubricated by the medium to be transported, the medium with poor lubricity should not be transported by shielding pump. Generally, the viscosity of the pump medium is 0.20mPa.s.(2) the efficiency of shielding pump is usually lower than that of single end mechanical seal centrifugal pump, which is approximately equal to that of double end mechanical seal centrifugal pump(3) long time in small flow operation, shielding pump efficiency is low, will lead to heat, make the liquid evaporation, and cause the pump to dry, and thus damage the sliding bearingsCanned pumps can be divided into the following types: 1) basic type 2) reverse circulation type 3) high temperature type 4) high melting point type 5) high pressure type6) self priming 7) multi stage 8) mud type

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 a concrete pump and a concrete pump truck?

Concrete pump and concrete pump truck are concrete conveying machinery, use the same, but the former need to transport and car towing need additional support pipeline, the locomotive body and arm extends freely, without pipeline, hundreds of thousands of millions of the former, the latter

Q:How to select metering pump head?

The manufacturers of chemicals will give relevant recommendations, or consult the ProMinent chemical corrosion chart to determine the compatibility of the chemicals with the contact material.

Q:There are 6 pumps, two indoor fire hydrant pumps, two spray pumps, two outdoor pumps, three units, one master and one spare control cabinet. From the control room to the control cabinet, is there only 3 lines or 9 lines?... How do I get it? Where does the hydrant line come from?

Spray pump in addition to remote direct Kai, there are modules to start function, that is, on the cabinet to add control module, bus linkage pump, in addition to the pressure switch, directly pumping function, a total of three functions.

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?

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.
