Production Introduction:
WQ blockage-free sewage submersible pump(hereinafter as pump) is untegrative motor and pump. Which is manufactured based on absorbing domestic and foreignadvanced technology and advantages. Impeller, designed with hydraulic model and made by precision casting, has the advantages of energy-saving, anti-winding and non-clogging,etc. At the same time, the pumps have a unique effect in the carriage of solid particles and long fibers garbage. Single or dual impeller structure ensures the pump has the higher efficiency when it has bigger flow. So this king of pump is a ideal drainage pumps for industries and cities.

- Q:When the water pump is started, why should it start when the outlet valve is closed? Thank you
- When the valve is closed, the flow of the pump is close to zero, the power of the pump is very small, which reduces the load that the motor starts to bear and has a protective effect on the motor. Therefore, the valve closed to start the pump.
- Q:What is the "variable" of a variable pump? Is the displacement change or the flow change? Thank you
- These two don't mean the same thing? That is, the pump outlet can be changed
- Q:Why does the centrifugal pump start with a closed valve and the axial pump starts with an opening valve?
- Because the characteristic curves of the two are different.The power of centrifugal pump decreases with the decrease of flow rate. When the flow rate is zero, the power is minimum, so the centrifugal pump is started with a closed valve.
- Q:Why adjust the centrifugal pump outlet valve can adjust the flow? What are the advantages and disadvantages of this method? Is there any other way to regulate the flow of the pump?
- The centrifugal pump at a fixed speed, the head is fixed, adjust the outlet valve to adjust the diversion area
- Q:Centrifugal pump flow, why can be adjusted through the outlet valve? Can the flow of the reciprocating pump be adjusted in the same way?. Why
- Reciprocating pump is a positive displacement pump, the volume change of flow is the unit of time, constant flow speed constant, can not rely on increased resistance to change the flow resistance increase is only leaked, only small changes in flow.
- Q:Water pump outlet valve sequence
- In order to prevent the generation of water hammer when the pump stops the damage to the rubber head, should be immediately set rubber head pump outlet, the gate valve and the check valve is not a very convincing reason to decide the order of habits in our hospital order rubber head, check valve, gate valve1. Check valve located in front of the pump, I do not know what the significance is too great to think of.2. The actual installation sequence shall be: soft fittings, check valves, gate valves. The pressure gauge is best installed on the water outlet of the pump, but it must be in front of the check valve.Reason: 1) the soft joint is used to reduce vibration. The connection between the pump and the piping system, of course.2) normal work, the gate valve is not operating, and the check valve is frequent action, so the probability of maintenance is larger, when the maintenance of the pump closed, the water outlet valve can be maintained without affecting the normal operation of the system.3) the pressure gauge is installed in the check valve, which can prevent the impact and damage of water hammer on the pressure gauge.
- Q:Why can't the inlet of centrifugal pump be negative pressure?
- The entrance can be a negative pressure. You can often see someone pumping water from the pool. How can you pump water if it is not negative pressure?
- Q:Know flow and lift how to calculate the pump power?
- The pump power (kw) ={9.61* flow (cubic meters per second) * head (m)}/.Where ETA is device efficiency, including mechanical, electrical loss and other factors, generally between 55%~80%. The smaller the pump, the lower the efficiency.
- Q:Types and differences of pumps
- Classification and working principle of pump by structureClassification of pumpsInvolved pump standard product types are also very much, a centrifugal pump, metering pump, screw pump, reciprocating pump, hydraulic pump, submersible pump, oil pump, water pump, pressure test pump, vortex pump, cryogenic pump, vacuum pump, roots pump, molecular pump, gear pump, mud pump, corrosion-resistant pump deep well pump, water pump, mixed flow pump, axial flow pump, boiler feedwater pump, liquid pump, injection pump, chemical pump, pump plugging and no leakage pump, plastic pump, fire pump and so on, there are many. Its name is divided according to some conventional classification methods such as pump vane pump volume, pump etc., some are divided by purpose such as sewage pump, pump and other health, some names are more random as diffusion pump, liquid nitrogen pump. As long as the production of this product, with standard requirements, through a certain application and approval procedures may produce a new The standard, but sometimes the content also has a repeated cross, quite. The domestic and foreign standards, the domestic standard is more than the number of foreign standards. In general, such as centrifugal pumps are widely used, the production history of the pump more standard (total standard centrifugal pump up to more than 100). As new standard pump leakage pump this rapid development is relatively small. This paper introduces the structure and working principle of the pump according to the classification of the
- Q:What is a feed pump?
- In general, high lift pumps are required with a front pump (which is similar to the feed pump of the landlord) or a low position;
