Q:Metering pumps related matters
1., exports higher than imports, avoid siphonage2. the pump head and the injection valve require vertical installation3., the attached pipe can be tightened by hand, please do not use the tool; the thread does not use the raw meal belt4. the supply voltage is stable and grounded5. installation environment clean, spacious, well ventilated) 1) metering pump suction is not normal
Q:Troubleshooting of diaphragm pump
In the application of the pump, these conditions are likely to encounter. Each situation can be divided into several possible reasons. This guide lists the causes of failures and gives appropriate corrective maintenance measures. The meaning of all the specific terms in the guide is listed later.Air valves - copper or stainless steel valves are bolted to the center of the pump by four bolts.The piston aluminum cylinder is enclosed in the air valve to control the gas flow.Cavitation - because the pump inlet for the amount of fluid to reduce or lack, the pump discharge is less than the amount of quantitative. In fact, the fluid chamber is full of fluid before it is discharged.Static pressure drop - the inlet pressure from the pump centerline to the free point - the inlet is measured in pounds, including the specific gravity and velocity of the fluid.
Q:How can the submersible pump level meter be connected?
Install liquid level controller, two position liquid level sensor, controller to buy manual, wiring according to wiring diagram.
Q:Does vacuum pump oil belong to dangerous goods?
Of flammable substances, but not included in dangerous goods!Does not belong to dangerous goods,
Q:Double floor sewage pump circuit diagram of a small problem
Question 3 when the water level is low, when the 1KA is connected, the pump will run depending on where your SS selector switch is located. Its left and right position, running pump and standby pump definition is different, left position is 1#, running 2# standby, right position is 2# running, 1# standby. Only inIn case the high level switch 2KA is connected, the standby pump may work at the same time.
Q:Is the sewage pump the same as the mud pump?
Sewage pump is mainly used for industrial wastewater treatment, sewage treatment, environmental protection has played a big role. Among them, the sewage pump is also a sewage pump with cutting wheel, such sewage pump can be chopped dirt, and then extract the sewage clean.
Q:What is the minimum continuous flow of a pump?
The minimum continuous steady flow can be obtained by test and, in general, the pump supplier will indicate(2) minimum continuous heat limited flow (.API) provides minimum continuous heat limit flow, which means the minimum continuous flow that the pump can maintain and that its operation is not impaired by the temperature rise of the liquid being pumpedMinimum continuous heat limited flow can be calculatedIn the formula, the Pe amount of the fixed axis power is.KW;P pump medium density, kg / m3;
Q:What are the characteristics of the piston pump?
main features 1 、 double plunger structure, small pressure pulsation, long life of gem ball.2 、 imported precious stones and precious stones to ensure accurate flow.3, through the RS232 interface and computer communication, can be directly controlled by the computer.
Q:What is the principle of a turbopump?
The working conditions of the turbine are different from those of the medium used, so the structure of the turbine is varied, but the basic working principle is similar. The most important component of a turbine is a rotating element (rotor or impeller) mounted on a turbine shaft with blades uniformly arranged along the circumference. The energy of the fluid is converted into kinetic energy in the flow through the nozzle, and when the fluid passes through the rotor, the fluid impacts the blade and drives the rotor to rotate, thus driving the turbine shaft to rotate. The turbine shaft drives the other machinery directly or through the transmission mechanism, and outputs mechanical work.
Q:What are the basic technical parameters of the pump?
The basic parameters of the pump, the basic parameters of the main performance parameters of pump are the following: first, water pump flow Q flow is the amount of liquid in the pump unit time delivery out (volume or quality). The volume of flow with Q that the unit is: m3/s, m3/h, l/s and so on. The quality of flow unit is expressed in Qm. T/h, kg/s and so on. The relationship between mass flow and volume flow is Qm= P Q density in P - liquid (kg/m3, t/m3), room temperature water P =1000kg/m3.
