A ductile power Manhole Cover is a type of manhole cover that is made from ductile iron, which is a type of cast iron that has been treated with magnesium to enhance its strength and ductility.
Overall, ductile power manhole covers offer a reliable and efficient solution for securing underground utility infrastructure while ensuring safety and ease of access for maintenance and inspection purposes.

Ductile power manhole covers are designed to withstand heavy loads and provide a durable and long-lasting solution for covering underground utility access points. They have a high load-bearing capacity, making them suitable for areas with heavy traffic, such as roads, highways, and industrial sites.
These manhole covers are typically round or square in shape and feature a solid design with reinforced edges to prevent cracking and breakage. They are often equipped with lifting handles or lifting points for easy access and removal during maintenance or inspection activities.
Ductile power manhole covers are known for their resistance to corrosion, making them suitable for use in various environments, including urban, coastal, and industrial areas. They are also designed to be slip-resistant, providing a safe walking surface for pedestrians and vehicles.
Additionally, these manhole covers may have features such as locking mechanisms or anti-theft devices to prevent unauthorized access or theft. They can also be customized with logos, markings, or color-coding to indicate the type of utility or service they cover.
Slurry pump picks easy to maintain hard
The so-called siege easily defend the city, the selection of slurry pump easy, you can choose your favorite, but not so arbitrary maintenance of the. 1, slurry pump should be started before the pump inlet valve, close the pump outlet valve. Then start the pump, start the pump and then slowly start the pump outlet valve, pump outlet valve opening size and speed, the pump should not vibrate and the motor does not exceed the rated current to grasp. 2, series pump with the start, also follow the above method. Just open a pump, you can end of the pump outlet valve to find a little (open size to a pump motor current rated current of 1/4 is appropriate), and then you can start two three Until the last stage pump, tandem pump all started, you can gradually open the last stage of the pump outlet valve, the size of the valve to open the speed, the pump should not vibrate and any level of pump motor is not over-rated current to grasp. 3, Slurry pump mainly for the purpose of conveying flow, so the best running flow control system installed flow meter (meter), in order to monitor the flow at any time to meet the requirements; in the cyclone with the piping system, slag system Filter press dewatering system also requires a certain pressure at the exit of the pipeline. Therefore, in this system should also be fitted with pressure gauge to monitor whether the pressure meets the requirements. 4, slurry pump in operation in addition to monitoring traffic, pressure, but also to monitor the motor do not exceed the rated current of the motor. Always monitor oil seals, bearings and other normal phenomenon occurs, the pump takes place or overflow pool, etc., and at any time.
