Centrifugal installation ZBKiT represents an aggregated decision of centrifugal pump units including necessary equipment and electric part (including instrumentation and control equipment)
At installation of centrifugal pumps at pump station and their work on individual pipelines an assembly insert, return valve, shutoff valves, diffusor are installed on pressure head communications.
Pump stations are equipped with high-speed one- and multistage centrifugal pumps of high productivity (to 3000 m/h and more). Electric motors more are often used as a drive for the pumps. Stations are equipped with systems of centralised control and management.
The largest pumps are capable to pump over several thousand cubic metre of oil an hour. Each pump station provides certain speed of oil movement on its site, to the following station. Linear speed movements try to support within 1-1,5 l / second. Main pipelines are equipped with means of local automatics.
Vertical centrifugal pumps are intended for vertical installation by shaft position. The basic advantage of vertical pumps of type B is smaller size in the plan in comparison with horizontal ones and convenience of configuration for some types of pump stations. These advantages are especially essential for large pumps.
Example. To select water air ejector for filling with water of centrifugal pump with calculated lifting height //вс = 5 m. Diameter of lifting pipeline тр = 300 mm, its length = 20 m. Duration of filling of pump and lifting pipeline should not exceed 5 minutes Absolute pressure in the network of pump station is 0,45 MPa. This pressure was decided to use for work of ejector during operating time of pump station. If the basic pumps do not work, filling should be made by means of circulating installation with the centrifugal pump, water air ejector and a vacuum tank.
Application of adjustable drive considerably raises economic indicators of pump stations, economy of electric power reaches 10-15 %, Application of adjustable centrifugal pump allows to reduce number of pumps at pump stations. For the group of three-four working pumps it is enough to have one adjustable pump.
Vertical centrifugal pumps (with vertical shaft) are widely used at pump stations of the first lifting at big fluctuations of water level in the source, and also for lifting of underground waters from boreholes. Usually these pumps are connected directly to vertical electric motor.
Pump stations ZBKiT-2-ЦНУ-Q-H- У2-1a possess a set of advantages:
Box is a building construction providing safety of the set of thermophysical parametres and protection of covered technological installations, equipped with necessary process equipment, instrumentation and control equipment and engineering communications, installed either on specialised object or on the installation place.
Box represents a basis which is simultaneously a frame of technological installation ZBKiT-2-УНД-Q-P- У2-1а or ZBKiT-2-ЦНУ-Q-H- У2-1а, having protecting constructions made of metal, three-layer, wall and roof sandwich-panels, entrance in the form of a door and equipped with electric equipment system inside.
On request of the customer it is possible to install the following in box: alarm systems (fire, gas hazard and not authorised penetration into the box), ventilation and heating systems.
For input (output) in the box technological pipelines, electric cables and wires sealed passes (gaps) are provided in box walls in a place convenient for installation. Knots of passes through protecting constructions are made in the form of tubes rigidly built in in building constructions, backlash between the pipeline and the tube (from both ends) is filled by non-flammable material admitting moving of pipeline along its longitudinal axis. Configuration of process equipment in the box is executed according to requirements of design documentation, GOST 32569 and other standard documentation confirmed when due hereunder.
Installations ZBKiT-2-УНД-Q-P-У2-1а or ZBKiT-2-ЦНУ-Q-H-У2-1а, built in in a box, is based on a frame which represents an integral welded design from a channel. Dosing pumps equipped with gauges of membrane breakdown are put on the frame, shutoff and control valves and fittings, instrumentations are mounted.
ZBKiT-1 – БДР-Q-P – У2-1а represents technological installation ZBKiT-2-УНД-Q-P- У2-1а or ZBKiT-2-ЦНУ-Q-H- У2-1а, built in in a box.
Centrifugal console pumps of ZBKiT type and electric pump units on their basis are intended for pumping over of chemically active and neutral liquids with density no more than 1850 kg/m3 and kinematic viscosity to 30*10-6 m 2 / with (30 cS) with volume concentration of firm inclusions no more than 1,5 % with the size of firm inclusions no more than 1,0 mm
