Detailed Product Description: | Bengbu is no negative pressure water equipment, frequency of water supply equipment Walter true zero-risk agent, willing to do your full intimate sales consultant! There you can not think of quality, service and price! Address: Lu Tin Road Changsha High-tech Development Zone on the 8th floor Oak Park 5 Tips: happy day is the day, unhappy day is also the day, why not happy about, make your life more laughter! What is no negative pressure water equipment lift represents what letter? What unit of measurement? And conversion and formula pressure? A: The unit weight of the liquid called lift pump by energy obtained. The head includes a suction pump included, is approximately pump outlet and inlet pressure difference. Head with H expressed in meters (m). Pump pressure P expressed by units of Mpa (MPa), H = P / ρ. As P is 1kg / cm2, then H = (lkg / cm2) / (1000kg / m3) H = (1kg / cm2) / (1000 kg / m3) = (10000 公斤 / m2) / 1000 公斤 / m3 = 10m1Mpa = 10kg / c m2, H = (P2-P1) / ρ (P2 = outlet pressure P1 = inlet pressure) What is the efficiency of the pump formula How A: refers to the effective power and shaft power ratio pump. η = Pe / P pump power usually refers to the input power, that power the pump shaft reached the prime mover, it is also known as shaft power, with P said. Effective power ie: pump head and mass flow rate and the acceleration of gravity. Bengbu no negative frequency of water supply equipment work process: 1. When pipeline pressure is greater than or equal to user pressure when the water pressure is higher than the user pressure, the bypass valve is turned on, the water is supplied directly by the water users. Users pressure is higher than or equal to the set pressure, frequency conversion equipment is not running, the pump is shutdown. 2. When the pipeline pressure below the user-pressure frequency conversion equipment is running, the pump is operational. A, pipeline flow is greater than equal to water users within the air flow regulator has if the pressure increases, and excess gas flow regulator can be discharged outside. So that the water flow regulator fills with water to prepare for the next peak period. When the water fills the flow regulator, vacuum mounted on top of the elimination of the flow regulator automatically shut down to prevent overflow. Flow regulator pressure to return to the water pipe network pressure. If there is no air flow regulator, flow regulator maintain the pressure within the water pipe network pressure. Pump upgrade for users of water pressure and the pressure of the pipe network in the difference. That pump provides users of water pressure head = - pipe network pressure B, flow regulator pressure to reduce network traffic when rain water users, when the flow regulator when the pressure is lower than atmospheric pressure mounted on top of the negative pressure flow regulator Elimination automatically opens allowing gas into the flow regulator, eliminate the negative pressure. The pressure drop to zero within the flow regulator. Flow regulator inside the water flowing into a common tap water supplied to the user. Reserve water flow regulator compensation is the difference between user and network flow of water. Pressure pump upgrade for users of water pressure. Bengbu no negative part of the frequency of water supply equipment: Combined pipe network overlying water supply equipment (with pumping stations), Intelligent electrical control system, low noise stainless steel multi-stage centrifugal pumps, automatic life without water tower equipment and backflow prevention device, Complete stainless steel piping, pressure, liquid level signal acquisition, feedback facility. a, starting balance and starting current limit at rated current, thus avoiding the impact on the starting grid; b, because the average pump speed is reduced, and thus extend the life of pumps and valves; c, can eliminate start and stopping the water hammer effect; Generally speaking, when an automatic life by the tower control a motor, just the automatic life without tower equipped with the motor capacity and the actual motor capacity can match. When an automatic life without tower control two motors simultaneously, in principle, automatic life without tower feature motor capacity should be equal to the capacity of the two electric motors and. However, if at the time of peak load of water supply quantity than two pumps at full speed a lot of difference, may be considered appropriate to reduce the automatic life without tower capacity, it should be noted there is adequate capacity. While the pump is running at low speed, motor current is small. However, when the user changes frequently water, the motor will be in frequent, deceleration state, and acceleration and deceleration of the current can be slightly more than the rated current of the motor, causing the motor to overheat. Therefore, the motor thermal protection is required. This temperature rise due to frequent acceleration and deceleration and accumulated, electronic thermal protection function to automatically live within the tower is difficult to play a protective role, it should be used for the motor thermal relay thermal protection. Part of Bengbu no negative frequency water supply equipment: 1, modular stainless steel water tank (with pump house). 2, intelligent electrical control system. 3, low noise stainless steel multi-stage centrifugal pump. 4, no negative pressure water equipment and anti-backflow device. 5, stainless steel tubing sets. 6, pressure, liquid level signal acquisition, feedback facility. Bengbu no negative after-sales service of the frequency of water supply equipment - heartwarming 1, the purchase of our water supply equipment customers, if demand our company will provide technical personnel on-site for a free installation and technical training; water supply equipment to meet the customer's site in 3 days to complete the installation. 2, Division I for the sale of water supply equipment for a period of 12 months warranty. The warranty period, the company free treatment of non-human factors and the quality of the equipment itself belongs to occur under normal conditions of use. 3, Division I for the sale of products to provide maintenance services for life. Ensure long-term spare parts supply equipment at preferential prices to ensure supply for at least 10 years. 4, the user equipment failure in the operation, issued in the user maintenance - repair notice after our confirmation, within two hours to give reply by fax or telephone; For on-site service, arrived at the scene within 24 hours in Hunan Province, the province 72 hours within the scene. 5, to provide customers with the non-confidential information required, upon receipt of (potential) customers non-fault information, to give a reply within one working day (8 hours). |
