Q:Operating procedures for measuring pumps
start-up1. Adjust the stroke indication to zero by adjusting the nut or handle with the rotary stroke.2 open the outlet valve.3. Open the inlet valve, pump, exhaust from the high point, exhaust from the relief valve, the breather valve.4, point motor, check the operation of the pump.5. Start the motor.6, without pressure on the premise, every 15 minutes to improve the stroke 20%, if there is no pressure, do not substantially improve the stroke.Note: (1) whether the sound or vibration of the pump is abnormal (2), whether the stroke adjustment is automatic or not
Q:What is the series of pumps? What's the difference between a unipolar and a multistage?
You're talking about a centrifugal pump. His series says the number of slices of the impeller (excluding the wheel, that is, the wheel)
Q:What are the characteristics of a vertical multistage centrifugal pump?
Vertical multi-stage centrifugal pump is cast iron, the advantage is that the price is cheap, the disadvantage is bulky and power consumption.
Q:Is the diaphragm pump and the drain pump one?
Therefore, the need to play a liquid discharge pump, if the medium is corrosive liquid, high viscosity, volatile, flammable, highly toxic liquid, you can choose diaphragm pump. Conversely, the general liquid, there is no special requirements, you can use the general centrifugal pump to reduce costs.
Q:What are the internal losses in centrifugal pumps? How did they come about?
Due to the friction of the bearing, the friction in the stuffing box, and the losses caused by the rotation of the impeller (the loss of the roulette wheel);
Q:What is the pump, how to classify, mainly used in where?
1. vane pumpThe impeller pump is driven by the impeller to rotate the liquid at high speed and transfer mechanical energy to the transported liquidAccording to the pump impeller and runner structure characteristics can be divided into different:1) centrifugal pump2) axial flow pump3) mixed flow pump4) vortex pumps3. jet pumpA high velocity jet produced by a working fluid is used to eject the fluid, and then the energy of the ejected fluid is increased by momentum exchange
Q:What are the starting and stopping procedures for centrifugal pumps?
The use of centrifugal pump can be divided into three steps, namely, start, run, stop.Start: you should do the following preparation before starting:(1) check the water pump equipment in good condition.(2) the bearings are filled with oil, the oil level is normal, and the oil quality is qualified(3) all the inlet valves of the centrifugal pump are opened.(4) pump water injection or vacuum pump diversion (except for flow), open the vent valve exhaust.(5) check the leakage of shaft seal. It is advisable to fill the seal with a little drop of water.(6) the motor rotates in the right direction.
Q:What is the dry running protector of screw pump? What's the principle and function? Thank you
When the temperature reaches a certain value, the signal is transmitted to the electric control box through a dry running protector, and the electric control box is used to stop the screw pump so as to protect the screw pump.
Q:Why does the centrifugal pump start and close first when the outlet valve is closed?
The contact is burned out, the bond and so on the accident, therefore closes the outlet valve, starts the electric machinery, at this time the electric machinery belongs to the no-load current movement, greatly reduces the big current impact
Q:What's the submersible pump?What is a submersible pump, and what about it?
Deep well submersible pump is a fountain, drinking water transportation, irrigation, hot springs, high-rise transport facilities, etc., deep well submersible pump excellent performance, so widely used in various fields.
