Q:What is an industrial water pump?
The pump has the different uses, conveying different liquid medium, different flow rate, different lift range, therefore, its structure of course is not the same, the material is different, in general, can be divided into:1, urban water supply 2, sewage system 3, civil and construction systems 4, agricultural water conservancy system 5, power station system6. Chemical system 7, petroleum industry system 8, mine metallurgy system 9, light industry system 10, ship system
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:What is the pump delivery? What's the difference between years and years?
1) integer integer: ~ batch. Sell ~.2) buy in bulk: ~ goods. Sell now.The exchange is, according to the duration of the contract delivery insurance premium, payment is generally in common, 5 years of insurance you every year that time, continuous call five years; general single sex 5 years or even 10 years of premium.Furthermore, the insurance premium is good or good pay period, if a single rate from the point of view, to make cheaper than single period, but considering the one-time payment of the interest cost of funds and the opportunity cost, there is no difference. While the single cross ratio advantage is mainly reflected in its flexibility. First of all, additional premium may be added to the premium. At present, additional risks can only be covered if the main risks and principal risks are covered during the payment period. The single way to buy insurance, even in the primary insurance protection period will no longer be able to purchase additional insurance new; secondly, to pay the premium can enjoy a premium waiver. If the insured in full payment period has not yet had the danger, not pay part of the premium would be exempt from the Qing dynasty. For child insurance, the premium waiver is more advantageous. If parents unfortunate accidents or illness, resulting in death or one or two, three disabled or suffering from severe illness, the insurance company will be exempted after the premium, the insurance contract shall continue to be valid; finally, to pay the premium or additional premium amount can be changed. The policy holder may adjust his insurance plan according to the change in his economic strength. In contrast, single premium has the advantage of a one-time payment more convenient.
Q:What is the nominal pressure of the hydraulic pump and hydraulic motor?
Related concepts of hydraulic motorsFlow theoretical volume refers to the volume of oil inhaled in unit time without leakage.
Q:Why can the centrifugal pump hold down the pressure?
The centrifugal pump can hold pressure because of the suction pipe in the pump at the entrance of a non-return valve (valve).
Q:Water pump spoon pipe for power plantWhich hero can tell me what is the water pump spoon tube ah? And its role
By adjusting the amount of oil entering into the hydraulic coupler, the torque of the hydraulic coupler can be controlled
Q:Centrifugal pump flow, why can be adjusted through the outlet valve?
First of all, we know that pump according to the principle of work is divided into speed and volume type, centrifugal pumps are speed type, and reciprocating pumps are volume type.The centrifugal pump can adjust the flow through the outlet valve and outlet valve opening can determine the pump flow and head performance curve parameters such as specific relationship between the outlet flow and pressure can be provided by the data pump manufacturers endplate that even close the outlet valve of the pump pressure will also have a fixed value, but not allow zero flow pump operation, vibration caused by damage to the pump on the mechanical seal is not good and so easy to cavitation, set the minimum reflux line.
Q:What are the conditions required for hydraulic pumps to complete oil absorption and compression?
Volume conditions: oil absorption cavity from small to large, complete oil absorption, oil pressure chamber has become smaller, complete pressure oil.Sealing conditions: the hydraulic pump itself should have good sealing
Q:Why adjust the centrifugal pump outlet valve can adjust the flow?
The centrifugal pump at a fixed speed, the head is fixed, adjust the outlet valve to adjust the diversion area
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.
