Product Description:

Product overview

AY type centrifugal pump series, it was in Y type oil pump series on the basis of modification and redesign. It is to meet the needs of modernization, as soon as possible to adapt to energy saving centered equipment upgrading and development of new products. I plant production AY type pump in the case of without affecting the interchangeability, some parts of the original design is not reasonable place is improved.

Application field

AY type pump can be used in the oil refining industry, petrochemical industry, coal chemical industry and other places.
Product features

1. Bearing body parts to the original 35, 50, 60 Y type oil pump bearing body with 45, 55, 70 bearing replacement, improve the reliability.

2. The hydraulic flow components used the high efficiency and energy saving of hydraulic model, the average is more efficient than the old Y type oil pump 5-8%.

3. In order to keep the inheritance, AY type pump structure, installation size, performance parameters, material level to keep the same as the Y type oil pump, is advantageous for the renovation of the old mechanism.

4. Parts generalization degree is high, the general standard parts for several series of products share.

5. Select material refining, subject to Ⅱ, Ⅲ materials mainly. Bearing body parts such as increase of cast iron, cast steel, as the cold area, outdoor use, such as Marine provides favorable conditions.

6. Bearing free air cooled, fan cooling, the cooling system of water-cooling three, according to the different temperature of pump selection. The fan is especially suitable for cold water or areas of poor water quality.

The working conditions

Traffic: Q = 2.5-600 m3 / h

Head: H = 30-670 - m

Temperature: t = - 45 ~ + 420 ℃ (multistage pump - 20 ~ + 200 ℃)

Q:Filter backwash pump for what use, what is the principle of work ah?
When the filter is in normal operation, the impurity will be trapped in the upstream of the filter (filter medium). As the accumulation of impurities, the filter media will be blocked, and the direct performance is that the circulation will decrease. Usually, when the flow drops to a set point (the industry is usually judged by the pressure drop),
Q:The distance from the pump button to the ground
After confirming that the fire pump has started running, issue a command signal to the hydrant button to light the green answer light.
Q:No negative pressure water supply equipment, both the main pump and auxiliary pump, power is not the same
1) microcomputer frequency conversion control cabinet2) water pump unit3) current stabilizing compensator4) vacuum suppressor5) all kinds of pipe fittings, valves and so on
Q:How can I buy a pump?
Selection principle of pump:1, so that the selected pump type and performance parameters meet the unit flow, lift, pressure, temperature and other requirements, the most important thing is to determine the voltage, the maximum lift, and when the head high reached much traffic.
Q:What do you mean by the self coupling device on the pump?
Installation of GAK self coupling device:The installation of automatic coupling submersible sewage pump is mainly the installation of coupling device and the lifting of pump. In the pump before the installation of the rings on the chain, and the pump used for lifting.Installation procedure of coupling device:The coupling frame with four bolts fixed on the pump body; the water outlet pipe is fixed on the substrate; positioning cone mounted on the pipe seat; the lower end of the guide pipe is sleeved in the positioning cone, the upper end is sheathed on the guide rod of the rubber block; the guide rod frame is fixed on the pool wall. The function of the rubber block: the axial compression degree of the rubber block is adjusted by the screw on the guide rod frame, so that the diameter of the rubber block is consistent with the inner diameter of the guide rod, and the guide rod is stable.
Q:Know flow and lift how to calculate the pump power?
The pump power (kw) ={9.61* flow (cubic meters per second) * head (m)}/.Where ETA is device efficiency, including mechanical, electrical loss and other factors, generally between 55%~80%. The smaller the pump, the lower the efficiency.
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:Fire control center manual start fire pump directly, multi line control
Multi line linkage NHBVR-4*1.5 is a positive pressure blower and smoke exhaust machine fire fighting equipment
Q:What is a solution pump?
Principle and structure features of canned motor pumpThe ordinary centrifugal pump is driven by coupling the pump impeller shaft is connected with the motor shaft, the impeller and the motor rotates while working and shielding pump is a kind of non seal pumps, pump and motor is sealed in a medium filled by pumping the pressure vessel, the pressure vessel only static seal and, by a group of wires to provide a rotating magnetic field and drive the rotor. This structure eliminated the traditional centrifugal pump with a rotary shaft sealing device, it can do no leakage.The pump and motor pump together, motor rotor and pump impeller fixed on the same shaft, use of shielding the rotor and the stator of the motor rotor separated in the medium, its power is transferred to the rotor through the stator magnetic field.
Q:What's the difference between a concrete pump and a concrete pump truck?
Concrete pump and concrete pump truck are concrete conveying machinery, use the same, but the former need to transport and car towing need additional support pipeline, the locomotive body and arm extends freely, without pipeline, hundreds of thousands of millions of the former, the latter
