FAQ

What is the displacement of the pump? Flow? What is the volume efficiency and mechanical efficiency of the pump?

Pump flow: the volume of liquid discharged per unit time.(3) volume efficiency of pump: the ratio of actual output flow of pump to theoretical flow rate.

What is the function of a submersible pump?Do you have any knowledge about submersible pumps?.

Important equipment for deep well water extraction. When in use, the whole unit dives into the water. The extraction of groundwater to the surface is water, mine rescue, industrial cooling, irrigation, water lifting, ship ballast, also can be used in fountain landscape, hot water submersible pump for hot spring bath, but also can be applied to the extraction of groundwater from wells, can also be used in rivers, reservoirs, canals and other water projects. The utility model is mainly used for farmland irrigation and water for human and livestock in mountain areas, and can also be used for central air conditioning cooling, heat pump units, cold pump units, cities, factories, railways, mines and site drainage. General flow can reach (10m3~650m3) per hour, head up to 1500 meters.

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.

I would like to ask, constant pressure pump set pressure 20Mpa, the actual load is 15Mpa, then the constant pressure pump outlet pressure? If it is 20Mpa, then where is the loss of 5Mpa? If 15Mpa, the constant pressure pump 20Mpa how to understand? In addition, the constant pressure pump pressure is defined when the flow began to reduce the point, or a sharp drop in flow after the point?

15MPa. 20MPa means that if you enter the 20MPa, the variable mechanism will work, and the flow at this time automatically matches the load. 20MPa used to supply the fuel by maximum displacement.

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).

Do you have a suction pump higher than 9 meters?

Since the atmospheric pressure has been basically determined, the theoretical suction degree of the pump is more than 10 meters.

How long does the fine stone pump need maintenance? What should I pay attention to?

Filter backwash pump for what use, what is the principle of work ah?

But the reverse cleaning can not completely regenerate the filter medium, or there will be some impurities remain, when the regeneration of residual impurities (pressure drop) to set the value, you need to replace the filter (filter media).
