Q:Submersible pump and self-priming pump which is easy to use?
Pump generally installed at less than 7 meters from the water surface, if not meet this requirement, have to use submersible pumps, such as deep wells. Submersible pump is obviously not good, easy to malfunction, have to use.Self-priming pump is mainly convenient, but the performance is lower than the general centrifugal pump.There are both advantages and disadvantages at the same time, which is not easy to use.The key is where to use and how many parameters............
Q:The car water pump is broken. What are the symptoms?
Car water pump damage, water temperature will rise sharply
Q:22KW pump motor direct start circuit breaker and contactor size? Concrete calculation method
22KW the water pump motor is 380V. 22KW rated current is about 44A, 10 square copper wire is enough, the motor will often start off ah, if it is not available for DZ108-63 50A, CJX2-50 50A contactor is 380V.Pump motor (pump motor) according to the structure classification, should be divided into horizontal motor and vertical motor. Because of the work characteristics of pump starting torque is relatively small, the starting frequency is relatively small, relatively long time continuous operation and other characteristics, so the majority of pump motor asynchronous motor cage rotor or synchronous motor.The pump motor should be selected according to the selection of shaft power; motor shaft power power is greater than one level; for example: axle power is 15KW, select the motor should be: 18.5KW for motor with very few, according to the actual working conditions. 2 pole motor is generally used in the head of micro height, flow is not large (calculation is more complicated). Large flow, small lift occasions can choose 4 pole motor. Super large flow, lower head select 4 or 6 pole motor, when choose six pole motor, power can be reduced according to the shaft power of a grade.
Q:What are the new regulations in the design of main and auxiliary water bin and water pump room in coal mine?
The main water bin must have a main bin and an auxiliary warehouse. When a sump is cleaned, another water tank can be used normally.When the normal water inflow is below 1000m3/h, the effective capacity of the main water tank should be able to accommodate the normal discharge of 8h.The effective capacity of the main water bin can be calculated by pressing type in the mine where the normal water inflow is greater than 1000m3/h:V = 2 (Q+3000)Effective capacity of V-- main water bin in type m3;Q-- mine hourly normal water inflow, m3.However, the total effective capacity of the main water storage tanks shall not be less than the normal water inflow of 4h.The effective capacity of the water tank in the mining area shall be able to accommodate the normal water inflow in the 4H mining area.There is a big difference between the maximum water inflow and the normal water inflow in the mine. The drainage capacity and the water storage capacity should be specially designed.The water inlet chamber should be set up. A sedimentation tank shall be provided for the filling of water sand, hydraulic coal mining and other gushing water with a large amount of impurities. The water storage capacity of short positions must often remain above 50% of total capacity.
Q:Can the water from the fire pump enter the roof fire tank? Why?
Fire water pump water can not enter the roof, fire water tanks, "construction regulations" and "high regulations" clearly defined. The roof fire water tank acts as a temporary fire fighting water for 10 minutes, and the water in the fire pump is supplied directly to the indoor hydrant or sprinkler system. Roof water tank fire water can only be provided by the living pump.
Q:What is the function of open circulating water pump and shutdown in thermal power plant?
According to the water quality difference, the purpose is to provide the corresponding cooling water, for the system oil cooler, machine seal and other cooling. Open water directly from the circulating water pipe to use, the pump is delivered to the host, the small machine oil cooler, water quality is not very high, the circulating water drainage to the back pipe, water through the water filter filter impurities. The closed water takes the self closing water tank, which is used for removing salt water. General supply pumps, water pumps, sealing cooling water, condensate pumps, sealing water, generator, hydrogen cooler and other requirements of good water quality system, closed water self circulation, and through the cooler and open water circulating water heat exchange.
Q:Why should we pump water into a pump when the country uses a pump to pump it?
Because the leather cushion there is not completely sealed the water pump wall, there is a small gap in the contact, so that the piston up and down the air connection, air pressure is equal, can not pump water.And then add water to the gap closed, such upward pull the piston to make the piston below the space increases, but the air and can not go to fill the air pressure decreases, less than atmospheric pressure, only through inhalation of water to supplement water, which is forced by atmospheric pressure wells the water through the pipe and then rise to the pump. So it can be pumped up.
Q:How to measure the temperature of pump body?
It's the temperature of the pump motor!In addition to large pumps, water temperature is rarely monitored. Even so, the temperature of the pump body will not be measured.Since the water pump pumping, the leaves, vanes and shells are no temperature rise, the temperature is mainly concentrated in the bearing: small pumps rely on the work medium can play a role in reducing friction heat;Heating large pump mainly in the thrust bearing and guide bearing, if the bearing is lubricated by water cooling water, if there is oil lubricated oil cooling equipment specially, temperature monitoring of bearing large pumps can be installed in the pump thrust bearing temperature sensor to monitor the varnay.
Q:How to determine the pump installation elevation, why should we determine the pump installation elevation?
This depends on the water pump cavitation, in theory, suction is equal to the atmospheric pressure minus the margin, the installation is too high to suck the water ah. What kind of pumps do you want?.
Q:Is it illegal to produce aluminium submersible pumps?
When buying, if you ask for a copper wire or a wire, and don't answer you, it's against the principle of good faith. On the contrary, if you did not ask to buy the water pump with aluminum core, then there is no violation. Because the country does not have any laws and regulations prohibiting the production of aluminum core wire motor, naturally there is no aluminum wire motor as a fake and shoddy products, there is no pre notice obligations.In fact, the aluminum core motor is good, and the price is low, especially in the dry environment of small and medium-sized motors, with good performance. Only used in submersible pumps, because aluminum is easier to damp than copper wire, due to bacteria and other corrosion, and its life is sometimes less than copper wire. But the water pump, aluminum often needs to rewind coil, because of a small submersible pump motor is not good around general scrap.
Our main products are all kinds of centrifugal pumps, displacement pumps and vacuum pumps, such as oil pumps, multi-phase pumps, single stage and double suction centrifugal pumps, horizontal split case pumps, multistage pumps, axial-flow pumps, mixed flow pumps, petrochemical pump and submersible pumps.
