Structure

Pump designed according to National Standard ISO2858.Main parts are pump casing, pump cover, impeller, shaft, sealing parts and cantilever parts etc.
Pump designed at full back pullout, the pump casing and pump cover separate from impeller back face, Pump casing andpump cover are combined a working house; impeller, shaft, and rolling bearing are combined a rotor; cantilever support and bearing parts support the rotor. To balance the axial force, impeller rear cover have balance holes, impeller have wearing. If the axial force small, the impeller rear back hasn't wearing and balance holes.
IR pump have same construction type with the IS pump, pump cover and sealing hose are combined a cooling house, used for cooling packing and shaft, and prevent heat sending to bearing.
Bearing: adopt two radial ball bearing, ( IR pump is one set radial ball bearing, two set radial thrust-force ball bearing), installed in cantilever support, to support pump shaft, and bear pump axial force and radial force.
Seal: IS pump adopted packing seal, in seal, shaft sleeve installed to protect shaft; mechanical seal can be used according to user requirement.
IR Pump seal have two type: packing seal and mechanical seal, in pump cover have water sealing hole, outer water sealinghole and cooling house.
IY pump adopted mechanical seal; packing seal can be used according to user requirement.
Type of sealing and cooling has several kinds as follow:
(1) packing sealing: itself water sealing without cooling water
(2) packing sealing: itself water sealing with cooling water
(3) packing sealing: outer water sealing without cooling water
(4) packing sealing: outer water sealing with cooling water
(5) mechanical seal: without cooling water
(6) mechanical seal: with cooling water

Q:Fully automatic self-priming pump
Yes, design according to your different working conditions. For example, water pressure pump is pressure control, water pressure is low will automatically start, the pressure automatically shut down.
Q:What is the 10KV pump unit?
As the name suggests, the water pump unit is a number of pumps, and 10kV is the voltage level. According to the voltage level, what you call a water pump should be a pump with relatively large power
Q:What motor does the pump use?
Pump should use special water pump motor.Pump motor (pump motor) according to the structure classification, should be divided into horizontal motor and vertical motor. Because of the work characteristics of pump starting torque is relatively small, the starting frequency is relatively small, relatively long time continuous operation and other characteristics, so the majority of pump motor asynchronous motor cage rotor or synchronous motor.
Q:Flow 70 cubic meters per hour; lift 35 meters, choose what standard water pump?
If you want to install simple, you choose vertical single stage pipeline pump, he imports and exports in a straight line above, installation super simple. If the installation does not require, IS ah, GD ah, you can.
Q:What is the reason that the water supply of pump is getting smaller?
1, the water pump screen plug, should remove the filter screen sundries.2, the use of lift is too high. Over the pump range, the pump should be adjusted to use height or replace the pump head.3, pump impeller plug or wear, should remove the impeller sundry. Replace the impeller if worn.4, pump outlet pipe blocked by debris, should remove the debris in the pipe outlet.5, diameter and pump does not match, replace the outlet pipe.6, the pump cover gap is too large, increased pump volume loss, should adjust the gap.7, pump body and pump cover leakage, should tighten the pump cover screw, make the pump body and pump cover close coordination.8, the pump speed is low, the use of voltage is too low. Should adjust the voltage to the rated value, replace the thicker cable or avoid peak use.9, water pump diving depth is too shallow, there is air intake, should adjust the diving depth. Pump running depth is not less than 0.5 meters.Yi Mai water pump to help you answer, I hope to help you
Q:Is it illegal to produce aluminium submersible pumps?
No, the state does not have special laws to prohibit the use of aluminium wireIn fact, the aluminum core wire or mechanical or good, low prices, especially in the dry environment of small and medium-sized mechanical and electrical, with good performance. Only in the submersible pump, because aluminum is easier than copper wire, moisture infiltration, bacteria and other corruption, and its survival time is sometimes less than copper wire. But the pump inlet, aluminum often requires rewinding coil, because of a small submersible pump well around Electromechanical General scrap. Therefore, the quality of submersible pumps will not generally use aluminum, but the production of aluminum submersible pump is not illegal, but in the sale should be based on the principle of honest business detailed notification.
Q:Power flow conversion of water pump
Upstairs in Wurenzidi, pump power is related to the flow and the head, a simple formula: = /367 * power flow lift efficiency
Q:25KW what is the lift of the pump?
Never mind lift and power of pump, series and pump impeller diameter and impeller, the same power pumps may lift hundreds of meters, but the flow may be only a few parties may also lift only a few meters, but the flow may be hundreds of square. The general rule is that under the same power, the flow of the head is high, the flow of the head is low, and there is no standard formula to determine the lift, which is determined by the conditions of your use and the model of the pump.
Q:Why is the water pump usually used multi-stage pumps, while the circulating pump is usually a single-stage pump?
The circulating pump is usually used in the closed-loop system, circulating pump will be generated when the pump pressure, the pressure is also said, and the suction pump up is in normal pressure system, the outlet of the closed-loop system, when the system pressure is 0.1MPa, the water pump for water system needs higher than 0.1MPa, the difference of pressure difference the greater the water faster, on the contrary, the smaller the slower the pressure difference; so the normal work must want water pump outlet pressure is greater than the system pressure. The replenishment pump is usually multi-stage pumps, and circulating pumps are usually single pump is wrong, as long as the replenishment pressure difference to meet the requirements, multi-stage pumps and single-stage pumps are not affected.(single stage pump and multi-stage pump difference: 1, single-stage pump water level "is a wheel is a level", an impeller, no other brothers and sisters for help; and a plurality of multi-stage pump impeller, there are brothers and sisters for its help, so that his ability to work is high. Just as a man works alone and a lot of people work together, the work is differentTherefore, as long as the design requirements are met, it is not important to select multi-stage pumps and single-stage pumps.
Q:How can the pump be stationary?
1, the pump bearing lubrication interruption, bearing burn.2, locking the rotor is jam.3, foreign body corrosion serious impeller lock.
