There are many types of single-cylinder diesel engine self-suction and anti-pump fire pumps, of which the water discharged by the impeller to the gas separation room is returned to the water pores at the outer edge of the impeller’s leaf wheel. Under the influence of pressure differences and gravity, the water flowing back to the left water hole is shot into the impeller channel and broken by the impeller. After the air is inhaled from the pipeline, it is dumped into the snail shell. The gear pump, resistance pump, and fire pump flow in the direction of rotation. Then, combined with the water flowing from the right back to the water, it flows along the snail shell. Because the diesel pump continues to impact the leaf grid in the snail shell and is constantly being broken by the impeller, it is strongly mixed with the air to generate a mixture of gas and water. The mixture is stripped by the tongue at the exit of the snail shell and enters the separation room along the short tube. The air in the separation room is separated and discharged from the exit pipe, and the water still flows back to the outer edge of the impeller through the left and right pores, and is mixed with the air inhaled from the pipeline. This repeated cycle is gradually exhausted into the air in the pipeline, so that the water enters the pump and completes the self-suction process.

Fire pumps are a type of pump used in fire fighting. Compared to ordinary pumps, fire pumps have higher standards and requirements in terms of sealing, corrosion resistance and operational efficiency. Before running the fire pump equipment, we need to discharge the gas inside the pump, do you know what is the significance of doing so? The following is the answer from Shanghai Xizhiquan.

1. If there is gas inside the fire pump, then the equipment cannot form a sufficient vacuum during operation, resulting in the liquid not being able to be sucked up. This phenomenon is called gas binding, and is a phenomenon that often results from many operators not understanding this operation.
2, understand the formation of gas binding causes, we will understand how to avoid this problem occurs. Before the fire pump equipment is started, the pump casing needs to be filled with liquid. In the pump suction pipe mouth need to be equipped with a non-return valve, can effectively avoid the pump in the liquid due to gravity into the low tank, if the pump position is low, there is no need to carry out filling the pump.
3. The compressed gas inside the fire pump will occupy a certain space in the fire pump, making it impossible to seal it.

Therefore, the operation of deflating the fire pump before putting it into use can increase the vacuum of the equipment and increase the pumping capacity of the pump, thus effectively improving the efficiency of the equipment and reducing the waste of resources.

Control and adjust the installation height of the pump so that the installation height between the suction port of the pump and the liquid surface does not exceed the maximum allowable installation height, especially for mobile fire pumps, if they cannot absorb and discharge liquid normally, the installation height may be inappropriate. It can be solved by reducing the installation height or reverse installation;

Or add a small-capacity storage tank in front of the pump to increase the height of the liquid level and increase the static pressure, thereby shortening the distance between the liquid level of the suction storage tank and the suction port of the pump to prevent cavitation;

It can also prevent cavitation by reducing the flow resistance loss on the pump suction line. Shorten the length of the suction pipeline as far as possible within the allowable range, reduce the number of pipe fittings such as elbows and valves, and appropriately increase the diameter of the suction pipeline;

By improving the strength and abrasion resistance of the pump material, it can also effectively reduce the erosion of the pump caused by cavitation, so as to reduce the damage caused by cavitation to the pump and prolong its service life. In the selection of the impeller, it is possible to choose high hardness and high elasticity materials with strong cavitation resistance.

The domestic water supply equipment system is equipped with storage tanks and other water storage facilities, which saves the floor area and reduces the construction load, thereby saving a large amount of civil engineering investment costs. The intelligent and automatic operation of the equipment does not require a special person to be on duty, which saves management costs, and there is no water quality treatment instrument, which eliminates the need for regular cleaning and disinfection; the loss of system dripping, leakage, and overflow is reduced.

The application range of common domestic water supply equipment: waterworks, pressurized pump room, residential area, hotel and other buildings, enterprise production water, boiler circulating water system, farmland irrigation system.

What kind of terrain to choose what kind of water pump

This problem, in short, is the selection of water pumps. The following are the applicable way for you to choose water pumps from zjbetter. I hope they can help you choose water pumps and help you better. Choose the water pump that suits your design.
1. Confirm the use terrain
First understand the terrain in which the outfit is used, including temperature, moisture, air pressure, air cattiness, dustproof and leakproof conditions, and the position of dangerous areas.
2. Confirm operating conditions
Refers to the liquid face pressure( absolute) on the suction side of the liquid, the liquid face pressure on the discharge side, intermittent or nonstop work, fixed or mobile position, and the convenience of installation and conservation.
3. Confirm the nature of the medium
Medium temperature, viscosity, density, impregnated vapor pressure, solid flyspeck periphery and content, gas content, cattiness, volatility, trap, toxin.
4. elect the material of the pump bathe corridor
According to the physical and chemical parcels of the pumped medium above, the material of the inflow- passing corridor is determined.
5. Determine performance parameters
The performance parameters of the water pump can be determined by computation, analogy, test and other styles.
6. Determine the installation type
The installation of the channel is determined by the layout of the channel and the installation point, and there are direct connection, perpendicular and other types.
8. Determine the number of pumps
In general, spare pumps, especially fire pumps, are set up, and the number of pumps is named according to different situations.

1, impeller inflow channel blockage
First of all, the most intuitive problem, check whether the impeller is stuck in the main blockage, if so, timely cleaning can break theproblem.However, filtering bias can be added to the front of the pump bay to avoid the impeller runners being blocked again, If necessary.
2 、 Inside leakage
When the gap between the connection points of colorful corridor in the pump is too large, it’ll beget the pump to blunder, performing in a drop in discharge pressure. When this problem occurs, dismembering and form should be carried out.
3 、 Cavitation
still, performing in the pump bay pressure is lower than the impregnated brume pressure of the pumping medium, it’ll form cavitation, If the bay pipeline system has no blockage or the bay stopcock opening is too small. At this time, the blockage should be cleared or the bay stopcock should be opened wide, or the liquid position of the bay pool should be increased.
4 、 drop in rotational speed
Check whether the speed of the pump is reduced because of certain factors, the speed is commensurable to the head, if the speed of the problem, check the reasons, reasonable results.
5 、 Motor reversal
Observe the steering of the pump, if the steering is reversed, exchange the two cables on the outstations of the motor.

Starting with a cargo can beget damage to the motor, the factual use of head is too much lower than the pump nameplate head; submersible pumps without water work for too long.
First, first figure out whether the motor burn is burned comportments( mechanical failure) or burned coil( electrical failure).

still, substantially due toover-current, occasionally the voltage is too high or too low will also beget the coil to heat short circuit, If it’s the fault of burning the coil.

The vertical turbine pump is a vertical pump composed of single or multiple centrifugal or mixed flow impellers and guide casings, lift pipes, drive shafts, pump bases, motors and other components. The pump base and motor are located on the upper part of the wellhead (or pool), and the power of the motor is transmitted to the impeller shaft through the transmission shaft concentric with the lift pipe, which drives the impeller to generate flow and lift.
