Q:What's the difference between a centrifugal pump and a centrifugal pump? What are they used for?

Centrifuges are generally used to classify liquids of different densities in liquids.

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

There are many kinds of pumps, such as centrifugal pumps, piston pumps, diaphragm pumps, vane pumps, gear pumps, etc.

Q:If the suction pump does not have enough suction range, you need to add a vacuum pump to increase the suction stroke. How do you install the suction pipe of the vacuum pump? Water pump impeller is not closed, it is normal that the vacuum pump is unable to pump suction pipe to a vacuum, is it because the water pump outlet pipe connected to the role of the check valve? But the water pump, outlet pipe, check valve sealing performance can achieve the function of non leakage?

Vacuum suction principle of self suction pump:Assuming that the pump connected with the water inlet of a sealed container, the container has plenty of water, since the start of a water pump, water is thrown out of the water impeller pump body, water inlet seal vessel due to the extraction of water to form a vacuum cavity, this assumption will be connected to vacuum cavity and exposed to atmospheric conditions of water, water at atmospheric pressure under the effect of entry into the vacuum chamber".

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:Difference between pump and compressor

Working principle：The impeller is installed in the pump casing and is fastened on the pump shaft 3, and the pump shaft is directly driven by the motor. There is a liquid suction in the center of the pump shell, and 4 is connected with the suction pipe 5. The liquid through the bottom valve 6 and the suction tube into the pump.The liquid discharge port 8 on the pump housing is connected with the discharge pipe 9. Before the pump starts, the pump shell is filled with the liquid to be transported; after starting, the impeller is driven by the shaft to rotate at high speed, and the liquid between the blades must also rotate. Under the influence of centrifugal force, the liquid is thrown from the center of the impeller to the outer edge and obtains energy, and leaves the outer edge of the impeller at high speed to enter the volute pump shell.

Q:What are the reasons for sealing damage of centrifugal pumps?

Two, cavitation. Cavitation (mainly from a thermal centrifugal pump).Because the medium is hot water, the water temperature is too high to produce steam, the gas in the pipeline enters the pump cavity height, and the part of the gas can not be discharged, thus causing water shortage to run, the machine seal dry grinding is invalid, and the cavitation erosion device is not available.Process: replace the machine seal.

Q:What is the difference between swashplate pump and crankshaft pump?

Piston pump: valve plate, valve plate, piston, piston ring, crankshaft, connecting rod and so on, all belong to its spare parts.Piston pump working principle: by the piston in the pump cylinder for reciprocating movement to suction and remove liquid.

Q:Suction stroke and lift of water pump

The absorption process is also called the "largest self-priming height" (also can be understood as "the degree of self suction). Micro pumps do not add water at the circumstances, can automatically water suction pump up the maximum height (the vertical distance from the pump to be pumped from the mouth of pumping liquid).Generally lower than the water pump positioned equal when there is self-priming pump required capacity. For example, outdoor tourism, need to extract the water in the river, with the best micro pump self-priming ability (impossible to people ran to the river water inlet pipe with water. It) or pumping the liquid corrosion, easy to add water and so on occasions.

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:The suction pump has a nominal suction range of 30 metersHow deep can a well be sucked?Well, sixteen meters,

That is impossible. The suction height of the pump is caused by the centrifugal force of the vacuum. The water is sucked into the vacuum
