Overview of sand transporter：
The horizontal sand suction pump sand transporter is designed for transporting sand and soil in the field. It works by using a sand transporter to move the materials to a local area. Then, a high-pressure water gun and a sand suction pump are utilized to mix the solid and liquid components, enabling high-concentration, long-distance transportation. This sand transporter offers several benefits, including simple operation, environmental friendliness, energy efficiency, and durability. With its user-friendly design and efficient performance, it provides a reliable solution for the transportation of sand and soil, meeting the demands of various applications while minimizing environmental impact and maximizing productivity.
1. Customer case of horizontal sand suction pump
Haiyan County, Jiaxing City, Zhejiang Province is located in Hangzhou Bay, adjacent to the Hangzhou Bay Bridge. Due to environmental protection requirements, local sand mining is under control. There is an urgent need for a batch of sand and gravel for construction, so it is necessary to buy sand from other places and transport it to the local area by sand transporter, and then use a conveyor belt or a small mud pump to unload the sand, but this method is inefficient and costly. After the Marine pumping engineer made actual measurements of the local sand transporter，According to the requirements of sand discharge, a sand discharge scheme of 350PNS-35 horizontal sand pump was designed. Finally, 350PNS-35 sand suction pump is selected for sand pumping.
2. Project communication of sand suction pump
On April 10, 2018, the customer came to Tai’an Ocean Pump Co., Ltd. and put forward construction requirements: fast sand unloading speed, 6 water guns, and discharge distance of 600 meters to 1,300 meters. The engineers of our company showed the plan of sand (mud) transporter to customers, that is, to build a new boat, with 350PNS-35 horizontal sand suction pump and 350S44 high pressure water pump arranged in the cabin. Use the hydraulic operating lever to move the high-pressure water gun and the sand suction pipe, and then realize the sand unloading work of the sand transporter. This method is the sand unloading plan jointly developed by Tai’an Ocean Pump Co., Ltd.and Yancheng HeXinghua Shipyard, now it has been successfully promoted and operated for a long time in the middle and lower reaches of the Yangtze River and the Huangpu River area.
The customer recognized this scheme very much, but raised concerns about shipbuilding costs and delivery time, hoping to realize the idea of unloading sand at the terminal. Through the construction simulation on the field site, the engineers of our company put forward the scheme of placing the horizontal sand suction pump on the wharf and using the manual hand-held high-pressure water gun to draw water. However, several key points need to be paid attention to during the operation:
(1) The height of the horizontal sand suction pumpshould not be too high. The acuum suction range of the pump is limited. If it is too high, the first is to affect the suction and cannot guarantee the sand capacity; the second is to produce cavitation, which will cause the sand pump to wear out. Fast; The third is to reduce the head. There is air in the pump body and pipeline, which increases the resistance and shortens the conveying distance. Therefore, it is recommended to achieve backflow or parallel liquid level.
(2) If the on-site use conditions are limited and cannot be lower than the horizontal level, the actual level is within 2-3 meters, it can also be used, but it needs to be filled with water every time it is turned on. There are two ways to fill and divert water. The first is to add a bottom valve to the suction pipe of the horizontal sand pump, and then start the machine after pouring and diversion. Vacuum is achieved at the suction port, and the liquid is filled with the horizontal sand pump and the suction pipe. This solution requires an additional gate valve at the outlet, which is relatively simple to operate.
(3) When equipped with power and pipelines, it is necessary to consider the field requirements of the construction site. The 350PNS-35 horizontal sand suction pumphas a rated power of 200kw. However, considering the high concentration of the sand unloading scheme and long transportation distance, the engineer recommends an 8-pole 220kw motor; The sand discharge distance is relatively short, so you can choose 315mm or 377mm pipelines, and customers can choose according to the cost budget.
3. Introduction to Selection of Project communication of sand suction pump
After preliminary communication, the customer chose the 350PNS-35 horizontal sand suction pump to match the SK-0.2/2.2kw vacuum pump solution, and all motors selected Shandong Huali brand. This type of pump has sufficient stock, so the horizontal sand pump and The vacuum pump assembly connection experiment is completed and sent to the customer site.
Parameters of horizontal sand suction pump:
Model: 350PNS-35 sand pump
Flow：1800m3/h
Head: 35m
Power: 220kw
Motor: 8 level motor
4. How to choose the horizontal sand suction pump?
When selecting a horizontal sand suction pump, consider the following factors to ensure it meets your specific requirements:
(1) Pump Capacity: Determine the desired flow rate and capacity needed for your application. This will depend on the volume of sand and soil you need to transport within a given time frame.
(2) Pump Head: Assess the required discharge head, which is the vertical distance the pump needs to transport the sand and soil. Choose a pump with a head capacity that matches or exceeds your specific needs.
(3) Pump Efficiency: Consider the efficiency of the sand suction pump, as it affects both performance and energy consumption. Look for a pump with high efficiency to maximize productivity while minimizing operational costs.
(4) Construction and Materials: Ensure the pump is constructed with durable and wear-resistant materials, such as high-grade alloys, to withstand the abrasive nature of sand and soil. This will enhance the pump’s longevity and reduce maintenance requirements.
(5) Power Source: Determine the available power source at your location. Choose a pump that is compatible with the power supply, whether it is electric, diesel, or hydraulic, to ensure proper operation.
(6) Safety Features: Check for safety features such as overload protection, automatic shut-off, and reliable sealing systems to ensure safe and efficient operation of the pump.
(7) Support and Service: Select a reputable manufacturer or supplier that offers excellent customer support, technical assistance, and readily available spare parts. This ensures ongoing support and reduces downtime in case of any issues.
By carefully considering these factors, you can choose a horizontal sand suction pump that meets your specific needs, providing efficient and reliable transportation of sand and soil for your application.
