The working conditions
The work speed: 2950/1480 r/min
Medium: D type horizontal multi-stage centrifugal pump used for conveying water or physical and chemical properties of containing no solid particles similar Yu Qingshui
The liquid.
MD type coal mine with wear-resisting multistage centrifugal pump used for conveying solids content (volume concentration) is not greater than 1.5%
(particle size is less than 0.5 mm), the temperature is not higher than 80 ℃ of neutral mine water or other similar wastewater.
Liquid temperature: 0 ~ 80 ℃;
Flow range: 6.3 ~ 1200 m3 / h;
Lift range: 50 ~ 1140 m;
- Q: What are the internal losses in centrifugal pumps? How did they come about?
- Hydraulic loss: the loss of water by friction, eddy, impact, etc in a flow;
- Q: 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.
- Q: What is the minimum continuous flow of a pump?
- Quality solutionsMinimum flow of pump, minimum continuous flow of pumpIn order to ensure the proper use of the pump and the normal operation of the pump manufacturer will indicate the minimum pump in the sample of the continuous operation flow, the correct selection or use to warn or instruct users. According to the provisions of the API standard, the minimum continuous flow into the minimum continuous stable flow and continuous flow. Most small thermal limit(1) the minimum continuous stable flow.API standard specifies the minimum continuous stable flow refers to the vibration limit does not exceed the standard set by the pump can work normally. The minimum flow pump at small flow rate, there will be noise and vibration increase, API of this provision is to ensure that the service life of the pump, avoid due to improper operation of the pump caused by the adverse effects.
- Q: What is the dry running protector of screw pump? What's the principle and function? Thank you
- The utility model relates to a screw pump dry running protector, which is used for protecting the stator and the rotor of the screw pump from being transported by air
- Q: Why can the centrifugal pump hold down the pressure?
- Centrifugal pumps are vertical, horizontal, single-stage, multi-stage, single suction, double suction, self suction and other forms. Vertical centrifugal pump is referred to as submerged pump, molten salt pump and submerged pump. Centrifugal pumps use the impeller to rotate and cause centrifugal motion of the water to work.
- Q: Shielding pump is the main drawback of electricity? How much does it cost more than an ordinary centrifugal pump? Is there any noise in the running of the canned pump? How much is it lower than the noise of the common centrifugal pump?
- The graphite bearing lubrication medium, make the operation less noise and manual, reduce maintenance costs; in recent years, bearing material added with silicon carbide SIC, super hard, life is better than that of graphite bearing.The vertical structure can be installed on the pipeline like a valve, the installation is convenient and quick, and the motor and the impeller can be drawn out only when the utility model is used, and the pipeline is not needed to be removed.The utility model can be installed and run with a shock absorber or a damping pad, so that the pump is less noisy at running time.
- Q: Roots pump and dry pumpRecently involved in the work of the vacuum pump, don't understand this, is a ads602 vacuum pump, composed of roots pump and dry pump, is pre pumped to the 500mtorr equipment, the main pumping vacuum continues to 10mtorr, where the roots pump and dry pumps must be used? What role they play respectively. The so-called dry pump? Is refers to one kind of the pump, the pump is many dry pump? Also do not understand how the work of automatic switching system for pre pumping, the main pump, pump work alone did not connect system ah (of course there are even a butterfly) teach?
- Different working conditions, our company does dry claw pump alone can also achieve the vacuum of 133 PA.
- Q: What is the difference between the ground pump and the pump in the commercial concrete?
- What you should say here is the concrete pump.Ground pump: the pump will be placed in a position on the site, the pipeline will be sent to the construction of concrete surface,
- Q: Why can't the centrifugal pump pump the vacuum?
- Working principle (taking centrifugal pump as an example):Prerequisites, processes, and requirements for the overall system structure.
- Q: How accurate is the metering pump?
- The measuring accuracy of the stable metering pump is as follows:In a diaphragm metering pump, the reciprocating motion of the plunger is passed to the diaphragm through the hydraulic chamber between the plunger and the diaphragm. In order to maintain the normal movement of the diaphragm, the hydraulic chamber is required to keep the volume of the liquid in the space (usually using hydraulic oil) unchanged. In order to ensure that the volume of the formation of membrane movement is always equal to the stroke volume of the plunger pump, so as to maintain the stability of the flow, but in the actual operation of the pump, the plunger seal will inevitably cause leakage at the same time, there may be a gas into the hydraulic chamber
