Q:What is cavitation, centrifugal pump cavitation phenomenon how to solve?
Centrifugal pump cavitation phenomenon how to solve?:Measures to improve cavitation resistance of centrifugal pumps(1) improve the design of the suction port of the centrifugal pump to the impeller. Increase flow area; the radius of curvature increases the impeller cover inlet section, reduce the flow accelerated sharply with pressure; reduce the thickness of the blade, and the blade inlet rounded, close to the streamline, can also reduce the acceleration and pressure flow around the blade head portion of the impeller and the blade inlet part; improve surface finish in order to reduce the resistance loss; the blade inlet edge extends to the impeller inlet, the liquid flow in advance to accept work pressure, improve.
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 is a vacuum pump for?
In fact, the vacuum pump and high Swiss fan, high Swiss high-pressure blower, high Rui high-pressure pump principle is almost the same
Q:The suction pump has a nominal suction range of 30 metersHow deep can a well be sucked?Well, sixteen meters,
That is impossible. The suction height of the pump is caused by the centrifugal force of the vacuum. The water is sucked into the vacuum
Q:Water pump does not produce water, what are the reasons?
4. as a water inlet valve, check whether it is normal, whether the silted up.5. the installation height of water pump exceeds the allowable suction height of pump, or the suction pipe is too long.
Q:What are the problems that should be paid attention to when using vacuum pumps?
What are the problems that should be paid attention to when using vacuum pumps?
Q:Why is the sewage pump device coupler?
Advantages of installation and arrangement of sewage pump coupling:1. automatic coupling device, easy installation and maintenance. In the absence of automatic coupling device under the condition of fixed installation, such as pump fault maintenance personnel need to unscrew the screw pump lifting water, repair, or other small pump to pump the water down perfect maintenance, if the water is dirty, it would be difficult for people to go to the next, then the overhaul had great difficulty.
Q:What is the pump, how to classify, mainly used in where?
Classification of pumpsAccording to the principle of division:1. displacement pumpDepending on the movement of the work parts, the volume of the work increases periodically and reduces the suction and discharge of the liquid, and the pressure of the liquid increases directly by the extrusion of the working partsAccording to the different movement of moving parts, it can be divided into two types: reciprocating pump and rotary pumpAccording to the structure of the moving parts are different: piston pump and piston pump; there are gear pumps, screw pumps, vane pumps and water ring pump
Q:How to adjust the flow of piston pump?
For the swashplate valve controlled by the solenoid valve, the swashplate is in an angle with the cylinder body, so the plunger is reciprocating in the pump cylinder when the cylinder rotates. It goes from 0 degrees to 180 degrees, that is, to the upper plunger position, the plunger cylinder volume gradually increased
Q:How to select metering pump head?
In metering fluoride, we recommend the use of Viton, sealed PVC pump head. For most chlorination applications, it is better to use EPDM sealed NP (plexiglass) pump head. For hydrogen peroxide mixtures, only PTFE sealed PTFE pump head or stainless steel pump head can be used
