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:How many kilograms of water pump are there in the automatic washing machine on the market?

Longer service life. Automatic switch water pump, car wash automatically open and stop, easy to operate, not easy to bad, repair rate is low!!!

Q:What are the uses and precautions of magnetic pumps?

5, after the motor starts, slowly open the drain valve, until the pump into the normal working state, and then discharge valve to the desired opening;6, before the pump stops working, should first close the exhaust valve, and then turn off the suction valve.

Q:How to install, operate and maintain the pipeline booster pump?

Should be "People's Republic of China network security law" requirements, since June 1, 2017, the use of Internet services to carry out real name authentication account. In order to ensure your Baidu account can be used normally, please check the account number as soon as possible. Thank you for your understanding and support.How to install, operate and maintain the pipeline booster pump?Brother Yao s Gc76 2547 | browseRecommended for 2016-12-01 23:52:54 best answerThe installation of booster pump must be installed horizontally or vertically according to the installation method. The direction of flow shall be consistent with the arrow on the pump body, and installed as far away from the water level as possible. A valve shall be installed on the pump inlet line for ease of use and maintenance. When the impeller is the aspiration level below the pump on the pump shaft end or around the pump should be installed check valve, the outlet is connected with 13 links for water use, at first use to pump should be filled with water, and tighten the screw plug. The pipe connection should be tight, especially the water inlet pipe can not leak, otherwise it will reduce the pump head or not pumping water. The pump cavity is not water, not a long time running, so as not to damage the seal

Q:Water pump outlet valve sequence

Design specifications detailed manual instructions, divided into two cases:1, pump water first check valve, suitable for small caliber pipeline, gate valve to protect the non-return valve, not damage function;2, pump water out of the first gate valve, check valve for large diameter pipe, at this point valve easy to open and close;The setting of the check valve is mainly to avoid the high reverse speed of the pump and the condition of the submerged pump house. Set in the suction port of the pump, then stop the pump water flow will still affect the pump. In addition, the pump suction should try to avoid installing too many pipe fittings, so that the pump can maintain sufficient cavitation margin.

Q:What do you mean by the self coupling device on the pump?

Auto is an installation of the pump, which comprises a pedestal, self coupling frame, a guide rod and a guide rod support, the bottom fixed coupling frame, vertical installation of two guide rods can easily be brought down without installing the pump, the pump at the bottom of the pool, the outlet of the pump and the discharge tube can automatically lock, don't need to bolt connection, automatic coupling position, so as to achieve the effect of simple and convenient. When you need to repair, pump the pump up without jumping into the sink.

Q:Please give me professionals to calculate, the cylinder bore is 100 and the rate of 20m/s, the leakage can be ignored, but to the large flow pump!

3. efficiencyVolume efficiency, for hydraulic pumps, is the ratio of actual flow to theoretical flow. A hydraulic motor is the ratio of its theoretical flow to its actual flow.Mechanical efficiency, for hydraulic pumps, refers to the ratio of theoretical torque to actual input torque. The actual output torque of the hydraulic motor is theoretical torque to overcome the torque after friction, so the mechanical efficiency is the ratio of the actual output torque to the theoretical torque.

Q:What are the characteristics of a vertical multistage centrifugal pump?

A liquid that is primarily diluted, clean, non corrosive, explosive, or similar to water but contains no solid particles or fibers. Because of its high flow and large lift, it is widely used in fire fighting, water supply and air conditioning unit cooling water transportation in high-rise buildings.

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 pumping property of concrete?

Under a certain pump pressure, the farther or higher the concrete can deliver, the lower the probability of clogging, the better the concrete pumping performance.
