Product Description:

Production Introduction:
WQ blockage-free sewage submersible pump(hereinafter as pump) is untegrative motor and pump. Which is manufactured based on absorbing domestic and foreignadvanced technology and advantages. Impeller, designed with hydraulic model and made by precision casting, has the advantages of energy-saving, anti-winding and non-clogging,etc. At the same time, the pumps have a unique effect in the carriage of solid particles and long fibers garbage. Single or dual impeller structure ensures the pump has the higher efficiency when it has bigger flow. So this king of pump is a ideal drainage pumps for industries and cities.

Q:Piston filling and peristaltic pump filling which precision is high?
If the unit area is large, the accuracy of the plunger is certainly not high. The peristaltic pump is used by means of extrusion roller extrusion pump to promote the solution, this also depends on the unit cross section size, the same motor accuracy is very important.
Q:The working principle of magnetic pump
Control of cooling fluid flowThe pump is running, you must use a small amount of liquid in the magnetic separation between the rotor and the casing annulus area and sliding friction bearings for flushing cooling. The cooling liquid flow pump design flow is usually 2%-3%, the annular area between the magnetic rotor and sleeve of eddy current generated because of high heat. When the cooling and lubrication the liquid is not enough or poor flushing holes to plug, will result in permanent magnet medium temperature is higher than the operating temperature of the inner magnetic rotor gradually loses magnetism, the magnetic actuator failure. When the medium is water or water-based liquid, can make the annulus area temperature maintained at 3-5 DEG C; when the medium or hydrocarbon oil that can make the annulus area temperature maintained at 5-8 degrees.
Q:How to maintain and repair the booster pump of pipeline pump?
I. installationAssembly and disassembly1. scrub all the spare parts to be cleaned.2. mechanical seals are installed on the main shaft of the motor, and a small amount of clean turbine oil or 20 oil is added to the surface of the mechanical seal.
Q:Rotary vacuum pump does not meet the requirements of vacuum, what are the reasons?
(1) the disk, stator or bushing is worn and shall be inspected, trimmed or replaced with a rotary vane vacuum pump.(2) the pump temperature is too high, which not only reduces the viscosity of the oil, increases the saturated vapor pressure, but also may cause cracking of the pump oil. Ventilation, cooling and environmental temperature should be improved. If the exhaust gas temperature is too high, should be cooled before entering the pump, the environment temperature is high, should try to use a better high speed vacuum pump oil or 3# diffusion pump oil. (10) because of the deformation, wear or movement of the parts, the maximum opening height of the check head can be reduced or even unable to be opened, the intake of oil is too little, and the vacuum degree of the rotary vane vacuum pump is reduced, and should be adjusted as shown in the assembly section. Open high, more oil, but open too high, check valve in some places on the stop, it will not automatically drop, lost to prevent oil returns. The commonly used rotary vane vacuum pumps mainly include double stage rotary vane vacuum pump and single-stage rotary vane vacuum pump
Q:What are the characteristics of a pipe shield pump?
According to the transmission of liquid temperature, pressure, viscosity and particle level have different requirements, the pump can be divided into the following types: first, the basic type (standard type) transport medium temperature does not exceed 120 degrees, the head of not more than 100m, the pump other types are variations on the basic type and improved.
Q:Does the control cabinet of the fire control pump need to be related to the fire control room?
Automatic sprinkler, which is mostly used in this device or high water tank, the whole set of equipment must meet the most unfavorable point (the farthest the highest point of water) water pressure of the faucet.
Q:Why adjust the centrifugal pump outlet valve can adjust the flow?
This method can be used to regulate flow. The advantage is that it is simple and easy to use and the disadvantage is that the throttle consumes energy
Q:The difference between submersible pumps and centrifugal pumpsWhat's the difference between the two? What is applicable and what?
High speed rotating impeller blade drives the liquid to rotate, and the liquid is thrown out so as to achieve the purpose of conveying. There are many medium for transportation, such as oil, water, chemicals and so on. The pump shaft and the motor shaft are of the same shaft, the pump and the motor are made into an integral body and immersed in water. The medium of transportation is water.
Q:Brief description of centrifugal pump on / off operation
(3) check whether the turning rotor is easy and flexible, check the pump body is clang or friction sound.(4) the protective cover is installed, and the shield contact.(5) clean the pump frame and do a good job of sanitation.(6) open the inlet valve, make the liquid full of pump body, open the vent valve, clean the air and close it. If the hot oil pump, it is not allowed to open the air valve exhaust, to prevent hot oil channeling spontaneous combustion, if there is a dedicated vent pipes and tanks, you can vent the pipe line air and cold oil.(7) the hot oil pump should be preheated slowly before starting. Especially in winter, the pump body and the pipe should be preheated at the same time, so that the temperature difference between the pump body and the conveying medium is below 50 centigrade.(8) the oil must be sufficiently dehydrated before being introduced into the oil pump.
Q:What does the impeller on the centrifugal pump mean by the first cutting?
I used to do this job before. After the impeller is cut, the flow and lift will decrease. Sometimes, the same pump will be cut according to the needs of the impeller, so as to meet the actual needs, at this time, with the power of the motor will also be reduced
