Q:Excuse me, what is the water pump from the lotus root?

The utility model relates to a self coupling sewage pump, which is composed of a base, a self coupling frame, a guide rod, a guide rod, a support seat, etc., and the utility model does not need bolt connection

Q:What are the characteristics of the piston pump?

main features 1 、 double plunger structure, small pressure pulsation, long life of gem ball.2 、 imported precious stones and precious stones to ensure accurate flow.3, through the RS232 interface and computer communication, can be directly controlled by the computer.

Q:What is the nominal pressure of the hydraulic pump and hydraulic motor?

Working pressure - the actual working pressure of the motor, that is, the pressure of the input oil. The difference between the motor inlet pressure and the outlet pressure should be calculated.Rated (nominal) pressure under normal working conditions, according to the test standards for continuous operation of the maximum pressure, that is, the rated pressure, more than the maximum pressure is called overloading.

Q:Significance of water pump model ISO50-160

Meaning of water pump model ISO50-160: ISO- stands for international standard code (IS). 50- indicates that the inlet diameter of the pump is 50 mm (the complete model IS50-32-160 32- indicates that the outlet diameter of the pump is 32 mm). 160- represents impeller diameter.

Q:What does "efficiency" mean in a water pump catalog?

General pump efficiency is 60% ~ 85%. high efficiency of the pump, indicating the same work, the pump consumes the lowest energy, and vice versa

Q:Hydraulic pump displacement refers to the pump shaft what?

Displacement of the hydraulic pump refers to the axis of each turn, the volume discharged, called displacement, the unit is ml (ML),

Q:What are the characteristics of a pipe shield pump?

Two, reverse circulation type of shielding pump, its bearings, lubrication, cooling and motor cooling fluid flow direction and the basic type is the opposite. The main characteristic of reverse circulation pump is that it is not easy to generate cavitation. It is suitable for conveying liquid which is easy to vaporize. Sometimes it is also called "easy to vaporize" type. Three, high temperature medium temperature of up to 450 degrees. The cooling water jacket is usually added outside the shielding motor, and a cooling sleeve is added to the outer circulation pipe to cool the high temperature circulating liquid to reduce the temperature of the motor and the bearing. In the case of less power, some manufacturers do not use cooling liquid, but the outside of the motor is equipped with fins and the special winding to adapt to the working conditions, the use of temperature generally can not exceed 400 degrees.

Q:The difference between diaphragm pumps, vacuum pumps and centrifugal pumps

The diaphragm pump and centrifugal pump refer to the structure of the pump, and the vacuum pump means the use of the pump. There is no comparability between them.Centrifugal is the sign of inertia of an object. As the umbrella turns, water droplets move out of the outer edge of the umbrella and are thrown out. This is what is called centrifugal. Centrifugal pump is designed according to this principle. The high speed rotating impeller blade drives the medium to rotate and is thrown out so as to achieve the purpose of conveying.

Q:What is a positive displacement pump? He Weizheng displacement?

And includes a pump chamber (24) to open and a channel is arranged between the entrance and the pump chamber (26) in the second one-way valve (15), and one for the continuous displacement member (13) in the pump shell (10) in the travel section (S) actuating mechanism reciprocating motion.

Q:How about the depreciation of vacuum pumps?

(five) electronic equipment, for 3 years.The depreciation period of a vacuum pump can be calculated for 5 years. The expected residual rate is generally 5%, or it can be estimated by itself.
