Q:Pump operator's responsibility Sharing the rules, responsibilities, etc..
7., master the knowledge of concrete mix ratio, strictly forbid to add water to the pump at will.8., concrete mixing and workability, gravel diameter is too large, effectively refuse to pump.9. when the delivery pump fails, it can analyze the cause and quickly eliminate the trouble.10. pump complete, you must clean the pump body and pressure pipe residual.11. complete other temporary work assigned by the leader.
Q:What are the basic technical parameters of the pump?
The effective power of pump and output power, with Pe said. It is the effective energy per unit time from the pump in conveying out liquid obtained in the pump. Because the lift refers to the effective energy, pump output unit of heavy liquid obtained from the pump so that the product of head and the mass flow rate and the acceleration of gravity. Is to obtain the output from the pump in unit time of liquid effective energy - efficient pump power: Pe= P gQH (W) = QH (W) - P - density of liquid pumping (kg/m3); severe gamma - pump for transporting liquid (N/m3) - Q (pump flow; m3/s; H) - pump head (m); G (m/s2). The acceleration of gravity P axle power and effective power Pe is the difference of power loss in the pump, the size of the pump efficiency to measure the efficiency of the pump. As the effective power and shaft power ratio, with ETA said. Selection of related pumps:
Q:What is the difference between centrifugal pump and rotary vane pump?
Directly said vane pump on the line, generally do not say rotary vane pump.The centrifugal pump is divided according to the direction of the liquid flow in the impeller
Q:How accurate is the metering pump?
The measuring accuracy of the stable metering pump is as follows:In a diaphragm metering pump, the reciprocating motion of the plunger is passed to the diaphragm through the hydraulic chamber between the plunger and the diaphragm. In order to maintain the normal movement of the diaphragm, the hydraulic chamber is required to keep the volume of the liquid in the space (usually using hydraulic oil) unchanged. In order to ensure that the volume of the formation of membrane movement is always equal to the stroke volume of the plunger pump, so as to maintain the stability of the flow, but in the actual operation of the pump, the plunger seal will inevitably cause leakage at the same time, there may be a gas into the hydraulic chamber
Q:Water pump does not produce water, what are the reasons?
1 check whether the motor is reversed.2, to see whether the export, the entrance blocked, the outlet pressure gauge whether there is pressure.3, whether the pump selection is wrong, you can not suck up the water.
Q:What does centrifugal pump mean horizontally?
In other words, pump casing and pump body along the horizontal center of the pump leaves into the upper and lower halves, so that when the pump leaves the pump cover open, you can pump and bearings as a whole pumping out. No need to remove the pipe. I don't know. Do you understand?.
Q:What is the function of a submersible pump?Do you have any knowledge about submersible pumps?.
Submersible pumpThe submersible pump is composed of a control cabinet, submersible cables, water pipes, submersible pumps and submersible motors.Submersible pump main application and scope of applicationIncluding mine rescue, construction, drainage, agricultural irrigation and drainage, industrial water recycling, urban and rural residents cited water supply, and even rescue, disaster relief and so on.Classification of submersible pumpsAs far as media is concerned, submersible pumps can be broadly divided into three categories: clean water submersible pumps, sewage submersible pumps, sea water submersible pumps (corrosive).
Q:Fire hydrant pump button, under what circumstances do not need to install?
General high voltage system, when normal, use small pump steady pressure.Fire hydrant button lifting pump is one of the multiple pumping methods, and it is an important link of reliable operation of the system.
Q:Double floor sewage pump circuit diagram of a small problem
Q 2, SA and SS are select switches, and different positions indicate the same difference between the two nodes. SA hits the left position 13, 14 to connect, hits to the right position 21, 22 to connect. SS hit the middle position, 5 and 6 turn on, 7 and 8 turn on; hit the right position; 1 and 2 turn on; 11 and 12 turn on; hit the left seat; 9 and 10 turn on; 3, 4 turn on.
Q:What is the difference between centrifugal pump and self suction pump? Which is better?
In order to prevent the filling liquid into the pump shell because of gravity flow in the low groove, in the pump suction pipe at the entrance of a non-return valve (valve); if the location of the pump below the liquid level in the tank, then start without irrigation pump.Self-priming pump is a self-priming centrifugal pump, centrifugal pump is a kind of.Specific choice of a pump, depending on your specific parameters and conditions of use.
