Q:Water pump outlet valve sequence
Design specifications detailed manual instructions, divided into two cases:1, pump water first check valve, suitable for small caliber pipeline, gate valve to protect the non-return valve, not damage function;2, pump water out of the first gate valve, check valve for large diameter pipe, at this point valve easy to open and close;The setting of the check valve is mainly to avoid the high reverse speed of the pump and the condition of the submerged pump house. Set in the suction port of the pump, then stop the pump water flow will still affect the pump. In addition, the pump suction should try to avoid installing too many pipe fittings, so that the pump can maintain sufficient cavitation margin.
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:What is an industrial water pump?
The pump has the different uses, conveying different liquid medium, different flow rate, different lift range, therefore, its structure of course is not the same, the material is different, in general, can be divided into:1, urban water supply 2, sewage system 3, civil and construction systems 4, agricultural water conservancy system 5, power station system6. Chemical system 7, petroleum industry system 8, mine metallurgy system 9, light industry system 10, ship system
Q:Working principle and diagram of axial piston pump with pressure compensation variable
The size of the outlet flow pressure compensated variable displacement pump with outlet pressure of approximately in a certain range according to the constant power curve. When the pressure oil from the main part of the channel (a), (b), (c) into the inferior vena cava (d) variable shell, oil by the channel (E) respectively into the channel (f) and (H), when the spring force is greater than the oil (f) into the lower end of the piston ring servo hydraulic thrust area when the oil liquid (H) to the chamber (g), push the variable downward movement of the piston, the pump flow increases. As for the hydraulic servo piston end thrust force ring shaped area is greater than the spring when the servo piston moves upward, blocking channels (H), the (g) (I) through the cavity of the oil cavity pressure relief, at this time, the piston moves up, the variable head angle decreases, the pump flow rate decreases.
Q:Common failure treatment of piston pump
x09x09 (3) no connecting key on pump shaft or motor shaft1) break2) missing x091) replace key2) patch keyx09x09 (4) pump internal slide vice stuck1) the clearance is too small2) parts accuracy is poor, assembly quality is poor, gear and shaft coaxial deviation is too large; plunger head clamping; blade perpendicularity difference; rotor pendulum difference is too big, rotor slot has wound or blade has scar, force after fracture and stuck
Q:How long does the fine stone pump need maintenance? What should I pay attention to?
Daily maintenance of concrete pump, that is, routine maintenance in use, including inspection, cleaning, lubrication, fastening, adjustment, leak hunting, supplement of hydraulic oil, etc.. 8.1 hydraulic components inspection, due to the complexity of the equipment, we recommend practical experts to carry out the inspection of hydraulic system. If a fault is found, check the cause and repair the entire loop before proceeding to any operation. - found that oil has diarrhea, excluding leakage reasons. - inspect safety valves, hydraulic systems, steel tubes and hoses, fittings, cylinders, and find any wear and tear (pipe explosion may cause very serious consequences)
Q:What is the difference between swashplate pump and crankshaft pump?
In hydraulic system:Axial piston pump is the use of parallel with the transmission shaft in the plunger plunger reciprocating movement of the volume changes generated by the work. As the plunger and the plunger hole are circular parts, processing can achieve high accuracy with the high volume efficiency, stable operation, good flow uniformity, low noise, high working pressure, but the hydraulic oil pollution is more sensitive, more complicated structure, high cost.
Q:What does the pump mortar do?
In order to effectively reduce the flow resistance of concrete and pipe, to avoid obstruction caused by pipe sticking and to achieve normal pumping, and its role is generally only pumps.
Q:What are the problems that should be paid attention to when using vacuum pumps?
(1) check the vacuum pump line and the joint site regularly to see if there is any looseness. Turn the vacuum pump by hand and see if the vacuum pump is flexible.(2) add lubricating oil to the bearing body, observe the oil level at the center line of the oil mark, and the lubricant shall be replaced or supplemented in time.(3) plug screw vacuum pump of the water screw, filling water (or lead paste). (4) turn off the gate valve of the water outlet pipe and the outlet pressure gauge and the vacuum gauge. (5) point motor, and see if motor steering is correct.(6) start the motor. When the vacuum pump is in normal operation, open the outlet pressure gauge and the inlet vacuum pump. As soon as the proper pressure is shown, the gate valve is gradually opened, and the motor load is checked.
Q:What's the pump? Where can I use it?
Working principleIt transfers mechanical energy or other external energy of the prime mover to the liquid, increasing the energy of the liquid. 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. In the spiral case, the liquid slows down due to the gradual enlargement of the flow passage, and the part of kinetic energy is converted to static pressure, and finally flows into the exhaust pipe at higher pressure and is sent to the required place. When the liquid flows from the center of the impeller to the outer edge, a vacuum is formed at the center of the impeller. As the pressure at the upper level of the tank is greater than the pressure at the pump inlet, the liquid is continuously pressed into the impeller. Visible, as long as the impeller continues to rotate, the liquid will continue to be inhaled and discharged.
