Puhou Pump Industry Manufacturer Supplies Is Clean Water Pump Product Features

1. The single-stage single suction clean water pump is designed according to the performance and dimensions specified in the standard ISO2858, mainly consisting of the pump body, pump cover, impeller, shaft, sealing ring, shaft sleeve, and suspension bearing.

2. The pump body and pump cover of a single-stage clean water pump are divided from the back of the impeller, which is commonly known as the rear opening structure. Its advantage is easy maintenance. During maintenance, the pump body, suction pipeline, discharge pipeline, and motor are not moved. Only the middle connecting piece of the extended coupling needs to be removed to exit the rotor part for maintenance.

3. The pump casing (i.e. pump body and pump cover) constitutes the working chamber of the pump. The impeller, shaft, and rolling bearings are the rotors of the pump. The suspension bearing components support the rotor part of the pump, while the rolling bearings are subjected to the radial and axial forces of the pump.

4. In order to balance the axial force of the pump, most pumps are equipped with sealing rings at the front and rear of the impeller, and balance holes are provided on the rear cover plate of the impeller. Due to the low axial force of some pumps, there are no sealing rings or balance holes on the back of the impeller.

5. The axial sealing ring of the pump is composed of a packing gland, packing ring, and packing to prevent air intake or significant water leakage. If the impeller of the pump is balanced, the cavity containing soft packing is connected to the suction port of the impeller. If the liquid at the inlet of the impeller is in a vacuum state, it is easy to introduce air along the surface of the shaft sleeve. Therefore, a packing ring is installed in the packing chamber through the small hole on the pump cover to guide the pressure water in the pump chamber to the packing ring for sealing. If the impeller of the pump does not have a balance hole, there is no leakage problem due to the liquid pressure on the back of the impeller being greater than atmospheric pressure, so the packing ring can be omitted.

6. To avoid shaft wear, a shaft sleeve protection is installed at the part where the shaft passes through the packing chamber. There is an O-ring seal between the shaft sleeve and the shaft to prevent air intake or water leakage along the mating surface.

7. The transmission mode of the pump is connected to the motor through an extended elastic coupling. The rotation direction of the pump, when viewed from the drive end, is clockwise

Stainless steel submersible pumps have the characteristics of corrosion resistance, hygiene, energy conservation and environmental protection, no blockage, large flow rate, and strong passing capacity. They are widely used in drainage applications such as medicine, environmental protection, food, chemical industry, and electricity.
1、 Reasons and solutions for insufficient flow or failure to produce water during the operation of stainless steel submersible pumps:
1. The installation height of the stainless steel submersible pump is too high, resulting in insufficient immersion depth of the impeller and a decrease in the water output of the pump; The allowable deviation of the installation elevation of the water pump should not be arbitrarily expanded.
2. The water pump rotates in the opposite direction. Before the water pump is put into trial operation, idle the motor and check the direction to make it consistent with the water pump; If the above situation occurs during use, check whether the phase sequence of the power supply has changed.
3. The outlet valve cannot be opened. Check the valve and regularly maintain it.
4. The water outlet pipeline is not unobstructed or the impeller is blocked. Clean up blockages in pipelines and impellers, and frequently remove debris from the reservoir.
5. The wear-resistant ring at the lower end of the water pump is severely worn or blocked by debris. Clean up debris or replace wear-resistant rings.
6. The density or viscosity of the liquid being pumped is too high. Identify the causes of changes in water quality and take measures to address them.
7. The impeller is detached or damaged. Reinforce or replace the impeller.
8. When multiple water pumps share the same pipeline output, there is no one-way valve installed or the one-way valve seal is not tight. Install or replace one-way valves after checking the cause.

The reliable operation of chemical pumps includes two aspects: long-term operation without failure and stable operation of various parameters. Reliable operation is crucial for chemical production. If the pump frequently malfunctions, it not only leads to frequent shutdowns and affects economic benefits, but also sometimes causes safety accidents in the chemical system. For example, if the pipeline oil pump used as a heat carrier suddenly stops running and the heating furnace does not have time to shut down, it may cause the furnace tube to overheat or even burst, leading to a fire.
The fluctuation of pump speed in chemical industry can cause fluctuations in flow rate and pump outlet pressure, which can disrupt the normal operation of chemical production, affect the reactions in the system, cause material imbalance, and result in waste; Even causing a decrease in product quality or scrapping. For factories that require annual major maintenance, the continuous operation cycle of pumps should generally not be less than 8000 hours to meet the requirement of three-year major maintenance. API610 and GB/T3215 stipulate that the continuous operation cycle of centrifugal pumps used in the petroleum, heavy chemical, and natural gas industries should be at least 3 years.

QDN small stainless steel submersible pump has a compact overall structure, small volume, low noise, energy-saving *, easy maintenance, no need to build a pump room, convenient use, wide range of applications, not limited by usage conditions and scope, especially suitable for frequent movement or temporary emergency situations. It does not need to be fixedly installed, just put on a rubber tube or connect the tube, and place the submersible pump on the bottom of the water to level it, but it must be equipped with a safety control box to ensure safety. The submersible pump is designed using stainless steel stamping technology, which improves the surface smoothness of the pump body and impeller, reducing water flow friction loss to *, thus achieving significant energy-saving effects. At the same time, it also significantly reduces the volume and weight of the water pump, making it very suitable for situations that require mobile use.

The pump is entirely made of non-magnetic stainless steel casting when in contact with liquids, which has the characteristics of no pollution and corrosion resistance, expanding the use and application fields of submersible electric pumps. Stainless steel corrosion-resistant submersible pumps use single-phase (three-phase) power supply, which has small size, beautiful appearance, rust prevention, corrosion resistance, and can be used in general acidic and alkaline seawater.
