Diesel self-priming sewage pump set self-priming and non-clogged sewage in one, the use of axial return external mixing, and through the pump body, impeller flow channel design, can be like the general self-priming clean pump does not need to install the bottom valve and irrigation water, but also can suck and drain containing large particles solid and long fiber impurities liquid, It can be widely used in municipal sewage engineering, river pond culture, light industry, paper making, textile, food, chemical industry, electricity industry, fiber, slurry and mixed suspension and other chemical medium ideal impurity pump. Compared with similar products of the same kind, it has the characteristics of simple structure, good self-priming performance, strong sewage capacity, energy saving, convenient use and maintenance, etc., and it is in the forefront of the same kind of sewage pump products. The technical performance index is good, and it has broad application market and development prospect. Because the medium conveyed by the sewage pump is a mixed liquid containing solid materials, the requirements in sealing, motor bearing capacity, bearing arrangement and selection are higher than those of the general sewage pump. The key problems in selection and use are reliability, simple structure, strong sewage capacity and convenient use and maintenance, which are widely used in urban sewage pipe network system.

Methods of diesel self-priming sewage pump to improve self-priming capacity:

1. Install an suction bottom valve at the end of the suction pipe. Suction bottom valve is actually a check valve, it ensures that the water can only flow from the pool into the suction pipe and can not flow back, so if the suction pipe is filled with water, although the pump axis elevation is higher than the working water level of the pool, but because of the role of the suction bottom valve, the water in the suction pipe will not flow into the pool, so that the suction pipe has been filled with water to ensure that the pump can automatically and quickly start. The reliability of this water absorption method is affected by the quality of the water absorption bottom valve, for example, the closure is not strict, leakage, the water in the water absorption pipe will slowly flow into the pool, for a long time, there is no water in the water absorption pipe, resulting in the need for manual irrigation when the pump starts.

2. 
   

2. Reduce inlet pipe bends, drop height and horizontal distance.

3. Set the suction tank before the pump. This method needs to set up a suction tank on the pump suction pipe, before the pump runs, the tank should be artificially filled with water, after the operation stops, because the water inlet pipe height of the suction tank is higher than the water surface height of the pipe, although the water surface height of the pool is lower than the water surface height of the tank, the water in the tank will not flow back into the pool, so the suction tank can store a certain amount of water. And because the suction pipe of the suction tank (that is, the suction pipe of the pump) is lower than the height of the water surface in the pipe, it can ensure that the suction pipe of the pump is filled with water, and when the pump runs again, the water in the water tank is pumped away by the pump, and negative pressure appears in the tank, and the water in the pool is added to the suction tank under the action of atmospheric pressure.

4. Install a vacuum pump on the suction pipe of the water pump. Before the water pump starts, the vacuum pump starts first so that the suction pipe of the water pump is filled with water to ensure that the water pump starts automatically and quickly. This method of water absorption requires a perfect automatic control system to ensure normal work. Up.

The above are four ways to improve self-priming capacity, hoping to help you better use diesel self-priming sewage pumps.

Lightweight flood control emergency drainage pump equipment is a high-performance drainage pump specially designed for urban road waterlogging water. The pump shell material is made of stainless steel, the motor is made of permanent magnet synchronous motor, and the submersible special cable is used. The pump is characterized by small size and light weight, and is widely used in flood control and rescue, urban waterlogging and water removal in low-depression areas. 

Main features:

1, light weight, corrosion resistance: the pump body is made of light aluminum alloy material casting, other parts are made of high strength SUS304 stainless steel, all bolts are also made of stainless steel. Light weight at the same time rust and corrosion resistance is stronger, the weight is only one-tenth of the traditional pump. 

2, high efficiency: the use of permanent magnet synchronous motor, compared with ordinary motor efficiency increased by 20%, green environmental protection and energy saving. 

3, fast installation: two people can achieve the installation of the pump within three minutes, normal pumping operation, to solve the problem of pump installation. The water pump outlet adopts the form of quick connector, and the cable adopts the form of IP67 aviation quick plug, which is convenient for installation and quick connection, and the connection is safe and does not leak electricity. 

4, flow adjustable: pump speed can be stepless speed regulation, flow can be adjusted according to customer site conditions, to meet the actual drainage requirements, to prevent frequent start and close the pump. 

5, the operation is simple: the control box is started with one key, the knob speed is adjustable, the fault buzzer alarm, the fault emergency shutdown, the program fault one-key reset, the panel is clear and easy to operate. 

6, unattended: the pump comes with temperature control module, high temperature alarm stop. The control box comes with underload protection, when the water is pumped, the pump automatically checks

Measure the pumping condition, automatically stop the alarm after no water, prevent long dry operation, and truly realize the unattended emergency scene.

Because of its height and large water consumption, the secondary water supply pressurization equipment is an essential part of high-rise buildings. Why can't high-rise buildings do without secondary water supply pressurization equipment?

First of all, the tap water of high-rise buildings is insufficient to meet the pressure and flow requirements of the water in the building, so it is necessary to improve the system water pressure and increase the water supply in order to ensure the normal water demand of residents. The secondary water supply pressurization equipment is the key link to ensure the water pressure of the whole system.

Secondly, the high-rise building has a higher floor, each of which needs to have enough water pressure to ensure normal water use, so it is necessary to introduce a secondary water supply system and add secondary water supply pressurization equipment to compensate for insufficient water pressure. Through pressurization equipment, the water pressure is raised to a suitable range, and the household can enjoy a stable and balanced water service.

In addition, the secondary water supply pressurization equipment can also improve the utilization rate of water and reduce waste. By controlling the water flow and water pressure through the secondary water supply system, the rational operation of the pressurization equipment can minimize the water consumption and energy consumption, and reduce the operating cost of the secondary water supply system.

In summary, secondary water supply pressurization equipment is indispensable for the construction and operation of high-rise buildings. It not only ensures the normal water demand of households, but also saves water resources and reduces energy consumption, which is also of positive significance for the sustainable development of society.
