Pumping station project management and maintenance

Pumping station project management and maintenance First, pumping station project management In the rapid development of pumping station at the same time, the operation and management also made a lot of accumulated experience and achieved some success. However, it has long been affected by the idea of ​​"rebuilding the light pipe" and there are still some problems in management. How to manage, make good use of, good pump station project. And put it into the track of normalization, standardization and scientific management. The real management and management according to the requirements of infrastructures and basic industries are the central tasks of pump station management and an important measure to promote the sustainable development of water conservancy. (A) Organization Management Organization management includes: establish and improve the management agencies; clear terms of reference; rules and regulations. Do a good job of organization and management to improve the political and ideological level of workers, professional quality and technical level. It is very important to mobilize all the positive factors and ensure the completion of various production tasks at the pumping station. 1. The nature of the pumping station, institutions and capacity standards Pumping station is a grassroots water conservancy project management unit, but also the basic accounting unit. The main purpose of pump station management is to provide water services to society. In order to maintain and expand reproduction, pump stations should change their mode of operation and change the state that they do not talk about economic accounting, do not talk about project benefits, and losses depend on state subsidies. On the premise of fulfilling the task of providing water conservancy services, we will actively carry out diversified operations, strengthen economic accounting, and give better play to the comprehensive benefits of the project. Pumping station management agencies should be completed before the completion of construction. During the construction period, it will start training the technical forces, take part in the inspection and acceptance of the construction quality, and work with the design, construction and competent departments to formulate engineering and equipment management measures. Pumping station management unit should be based on the type of work, installed capacity and the scope of benefits, with reference to the "Ministry of Water Resources formulated by the water conservancy project management personnel setting standards trial" set the necessary management agencies and managers. Pumping station should be equipped with high quality, competent management personnel. In order to be beneficial to the management cadres, technicians and maintenance personnel to improve the management level and technical level, personnel should be kept relatively stable and should not be easily replaced or replaced. 2. The task of pumping station management agencies The main tasks of pumping station management agencies are: to fully mobilize the enthusiasm, initiative and creativity of employees with various legal, administrative, economic and technical means; to conduct effective command over the operation of pumping stations , Supervision and regulation; and strive to obtain the best economic efficiency with the smallest investment. Its specific tasks are as follows. (1) Collect relevant technical information from surveying and design departments and other departments; take part in inspection and acceptance of construction projects, take over engineering and related technical materials from the construction department, establish and improve technical archives and write memorabilia. (2) To formulate and implement various rules and regulations; to participate in the study and formulation of short-term plans and long-term plans for the development of pumping stations. (3) To formulate and implement the management plan, water supply and drainage plan, inspection and maintenance of engineering and mechanical and electrical equipment, and supporting and tapping potential renovation plans. ⑷. To promote advanced water supply and drainage technology; to carry out the necessary observations and experimental studies. (5) .Depreciation of depreciation and overhaul according to relevant provisions; timely collection and supply of water supply and drainage fees; comprehensive operation, ensuring the balance of financial revenues and expenditures and striving for self-sufficiency.经 often carry out civilized production and safety education; organize staff to learn culture, learn technology. 3. Technical Training In order to improve the water supply and drainage technology and improve the management level, we must strengthen the training of serving staff besides relying on professional schools to train qualified personnel. Pumping stations at all levels and pumping stations must have a special person to grasp the training. Such as the development of training programs, the implementation of training funds, training base planning, syllabus preparation, teaching materials and teachers hired. The form of training should be based on training objectives and training objectives, can be flexible. Such as teachers with only students, on-site training courses, special training classes Shenzhen, special seminars and so on. (B) project management The main task of project management is: do a good job in the control of the project, supporting updates to ensure the project intact, to ensure project safety. Extend the service life, give full play to benefits. The main contents of project management are: the management and application of hub buildings, the management and application of channels (river channels) and their buildings. Buildings in the long-term use. Often affected by natural and human factors, suffered varying degrees of damage. If not timely maintenance and repair, it will directly affect the reliability of water supply and drainage, shortening the service life of the building; the rational use of engineering facilities control or to play a significant impact on the effectiveness of the project. 1. Pump station management Pump station managers should be familiar with the details of civil construction, understand the civil construction, mechanical and electrical equipment installation, pump house and other building structures, various embedded parts, in order to facilitate future management. Pumping station project completed. To strictly implement the acceptance transfer procedures, all the survey design and construction materials received, archived custody. Then according to the original data, the specific circumstances of hydraulic structures and the existing relevant regulations, standardize and formulate engineering management systems and methods. Pumping station hub generally by the inflow of buildings, water buildings and pumping stations in three parts. ⑴ influent water inflow buildings connected with the diversion canal, it spread evenly to the water, smooth and even into the water pump or water pump suction pipe. The bottom pool of the front pool is generally 1 to 2 below the lowest water level, and consists of an anti-filtration section from the bottom section of the protection and is connected with the slope protection on both sides. Traps arranged regularly in the pool to prevent water and debris from entering the pump. Water meter installed beside the pool for water level observation. The management of inflow buildings should pay attention to the following points. 1) Check the slope protection works flushing damage. Found problems, should be promptly repaired. To avoid the slope. 2) Check the protection of the bottom of the project drainage is smooth, there is no earthwork, piping phenomenon. If it is necessary to promptly reduce the water level upstream, find out the reasons for repair, in order to avoid the pan under the floor of the pump room, causing major accidents. 3) During the water supply and drainage. Swimming in the pool is strictly prohibited to avoid danger. 4) Do not fish fish in the pool. No grindstone or thrown debris. 5) Pumping station operation, we must promptly remove trash rack before the debris, otherwise, on the one hand will increase the flow through the trash rack head loss and reduce the efficiency of the intake pool; the other hand, Of the uneven distribution of flow rate, affecting the performance of the pump and reduce the efficiency of the pump operation. 6) After the annual water supply and drainage, sludge and debris at the bottom of the pond should be removed and kept in a clean and good condition. ⑵. Outflow building The outflow building is connected to a pump room or pipe. It consists of the wall, the protection of the bottom, the gradient of several parts. The wall is equipped with a water gauge to observe the water level. ①. Out of the pool and the bottom of the wall separate masonry, often due to uneven subsidence cracks, resulting in leakage, such as serious water leakage, groundwater levels may cause too high, endangering the stability of the pump room. Therefore, we should always observe the presence of cracks, once found to be promptly repaired. ② .When the outflow pool and the pump house are built together, the side close to the pumping house is often overfed due to the backfill soil, causing uneven settlement, resulting in cracks in the outflow pool floor and the fracture of the wall on both sides. Therefore, we should always pay attention to observation, if there is a crack, it should be cut open, stuffed with cement mortar, if necessary, grouting. ③. When using the door to cut off, we should step up inspection and maintenance of the door, the shaft should always add lubricating oil. Otherwise, it will not open all the shutter doors or close them smoothly, causing an accident to the pumping station. ④. The pool wall is prohibited stacking heavy objects; the bottom of the pool is not allowed to impact. ⑤ out of the pool prohibit laundry, swimming and throwing debris. ⑶. Pump room pump room by the motor, pump layer, the water layer and the surrounding walls and other components. The management requirements of the pump room are: ① timely repair leaky roof. ②. Pump room should be kept clean. Prevent dust from entering the machine. Outdoor drainage should be smooth, so as not to rain into the pump room, affecting the safe operation of the unit. ③. To constantly check the pump room wall, in the piers, plates, beams, columns and the connection between each other, if any cracks should identify the reasons for timely treatment. ④. Make ground subsidence observation work. If the subsidence is not uniform, the concentricity of the unit will be destroyed, which may endanger the safe operation of the unit. Once discovered, should be dealt with as soon as possible. 2. Management of Culverts Culverts (such as intake sluices, sluice gates, flood control gates and various sub-divisions of culverts) in pumping stations and water supply and drainage areas are used for diversion and distribution of water by pumping stations. In order to ensure the flexible opening and closing of the culvert and the proper control and deployment of water, special personnel must be set up and operational rules and maintenance systems formulated. ⑴. Culvert gate requirements and opening and closing principles ①. Culvert gate should be intact. No gate erosion and destruction of the phenomenon. ② gate should be open and close flexible, and open the process and open without vibration. ③. Before the sluice water height should not exceed the design level; water capacity to meet the design requirements; and the correct control of water flow, ease of use. ④. For multi-hole gates, such as mechanical opening and closing, to open and close the holes at the same time, and open the same degree; such as manpower or mobile hoist open and close, first open the hole, hole. If the lifting height is larger, the grouting should be gradually upgraded to prevent the erosion of the downstream slope. Off gate when the symmetry of the first off both sides of the gate, after closing the hole. In this way, it is possible to prevent the water from flowing through the diversity or generating the bias current. ⑵. Opening and closing the gate Note ①. Before opening and closing the gate, should check the hoist, gate, gate slot, such as failure. Try to open and close the first time before use to ensure the opening and closing when opening and closing flexible. ②. When the gate is open, such as downstream without water, or the water level difference between upstream and downstream is above 1, in order to avoid the erosion of downstream channels and slope protection, the gate should be opened a little before the water level is raised and then gradually increased to the required height. ③ hoist hoist hoist, the force should be uniform. In case of trouble is forbidden to forcibly operate. ④ When the gate is opened, such as uneven distribution of downstream water flow or gate distortion, vibration, sound and other anomalies, should promptly check and deal with, in order to avoid failure to expand. ⑤. Gate barrier should be cleared before the rubble at the threshold, silt and other obstacles, so as not to gate closed lax. When the gate quickly dropped to the threshold, to reduce the speed of falling, so as not to drop too much, crashing parts or gates. ⑥. Close the gate, we must always pay attention to the degree of opening of the gate indicator to prevent the gate in the end is still rotating the rocker, causing the screw bending, or even under the top of the working bridge. ⑦. Unlimited switch on the straight gate, the use of rope drum closing machine, to prevent the gate to the top, the rope was pulled
