2. Excavator dredge pump 5 characteristics, which one do you know?
2.1 Stir and mix.
The bottom of the pump is equipped with a stirring impeller, which can be equipped with reamer or cage rack on both sides. This loosens the stiff sediment and improves the extraction concentration. The automatic hinged design prevents large solids from clogging the pump body and ensures that solid and liquid are fully mixed for easy handling.
2.2 High concentration.
The pump can handle solid substances with a maximum particle size of 50mm, and the solid-liquid extraction concentration can reach more than 70%. It should be noted that due to different working conditions, the output of the pump may vary due to factors such as processing media, field operations, and transportation distance.
2.3 Easy to use.
The equipment is mainly installed on the excavator, and the power is provided by the excavator hydraulic station. This allows for free movement. The equipment uses diesel engine as the power source, which can solve the problem of inconvenience in the construction of remote areas.
2.4 Wear-resistant material.
Flow parts such as pump shell, impeller, guard plate, impeller are made of high chromium alloy, and other materials can be customized according to demand.
2.5 Efficient sealing.
The equipment adopts a unique sealing device, which can avoid frequent changing of the machine seal and improve the work efficiency. The fuselage is made of solidly welded steel plates with high quality components. Each set of pumps has a master hydraulic cylinder and two side hydraulic cylinders, each hydraulic cylinder can be independently controlled, easy to adjust the cutting blade to suit the working conditions. The efficient, low-consumption jet pump is driven by a DC motor and gearbox for maximum efficiency at all times.
3. What is the price of a hydraulic excavator dredgepump?
The price of excavator dredge pumps varies according to different specifications. The main models of hydraulic submersible pumps are defined in terms of outlet or drive power. Therefore, the price of the submersible pump with the same power is basically the same, and the hydraulic submersible slurry pump mainly works with the hydraulic pump station or the excavator. Commonly used excavator specifications are 20 tons, 30 tons, 45 tons and so on. Of course, the bigger the pump, the higher the price, which is not going to change. However, some custom pumps will also be much higher than the price of the same power. The price of hydraulic submersible pumps with the same parameters is higher than that of electric submersible pumps, which is caused by the requirements and costs of hydraulic power.
4. What are the factors that affect the price of hydraulic dredge pumps?
The price of hydraulic submersible slurry pump mainly depends on the cost of flow parts and hydraulic modules. The main factors affecting the price of hydraulic submersible slurry pump are as follows:
4.1 Pump parameters
The parameters of hydraulic excavator dredge pump determine the type and caliber of pump. This determines the specifications of the pump, and the larger the specifications, the higher the price.
4.2 Material of pump
For different media, the material we choose is also different. However, it is usually made of high chromium alloy (only flow parts). For corrosive but not high media, we usually recommend high chromium alloy materials. However, if it is for highly corrosive media, the flow parts need to choose a corrosion-resistant material, which can be 304 stainless steel or 316 stainless steel. This material is much more expensive than high chromium alloy.
4.3 Agitator
The agitator here does not refer to the impeller at the bottom of each pump, but to the additional side agitator, usually 2. The main function of the agitator is to break up the bonded or viscous medium to facilitate the extraction of the pump. If an agitator is selected, the extraction medium concentration is relatively more uniform. At the same time, compared with the hydraulic submersible slurry pump without agitator, the price is more expensive.
4.4 Driving force of pump
The main reason why most customers choose excavator dredge pumps instead of electric submersible slurry pumps is that electricity is inconvenient in the field. Compared with the electric pump, the hydraulic pump can be directly driven by the hydraulic motor, and the electric motor is not required, so the use is more convenient and flexible. Therefore, most people use hydraulic submersible slurry pumps together with excavators. The hydraulic power of the excavator itself directly drives the hydraulic motor on the pump.
But some customers, they need a larger pumping depth, so close to the excavator is not enough to complete their requirements. At this time, the choice of hydraulic pump station is a good program. Can ensure the smooth field work at the same time, get more deep pumping. Therefore, the price of the hydraulic pump station accounts for a large proportion in the unit.
5. What are the 5 characteristics of hydraulic submersible pump?
5.1 The bottom of the pump is equipped with a stirring impeller, and can be installed on both sides of the reamer or cage, loosen the stiff sediment, improve the extraction concentration, automatic hinged, but also to prevent the larger solid materials will be clogged pump, so that solid and liquid fully mixed, so as to facilitate processing.
5.2 The pump can handle the maximum particle size of 50mm solid materials, solid-liquid extraction concentration can reach more than 70%.
Note: Due to different operating conditions, the output of the pump may vary depending on the processing medium, field operation, transport distance and other factors.
5.3 The device is mainly installed on the excavator, the power is provided by the excavator hydraulic station, can achieve free transmission, and the power source is diesel engine, construction in remote areas can solve the problem of inconvenient electricity.
5.4 Overflow parts: pump shell, impeller, protection plate, impeller are made of high chromium alloy, can also be customized other materials.
5.5 The use of unique sealing device, avoid frequent replacement of machine seals, improve work efficiency.
