Design Features
Any machine includes some standard components. They determine what functionality a particular type of equipment has.
bed
The bed acts as a load-bearing element. The remaining parts are attached to this part. Structurally, this part looks like two walls that connect to each other. Rigidity to a certain extent is given to it by the transverse elements that organize the connection. The machine is equipped with separate parts that move along the bed.
To solve this issue, special guides are provided.
- Three of the guides have a prism-shaped cross-section.
- One part is flat.
Headstock
The headstock is needed to simultaneously perform two functions:
- The workpiece is fully supported while processing is in progress.
- So that the part rotates in a certain way.
The front part of this equipment also contains handles responsible for controlling speeds. Thanks to this, the spindle can rotate at a certain frequency.
A special diagram is usually placed next to the handle. It is enough to study it once to understand when and what part is turned on.
The headstock in front houses a high-speed box, complemented by a rotating spindle assembly. Inside this part of the structure, special bearings can be used for rolling or sliding. The chuck of the device is fixed at the end of the spindle; a connection with threads is necessarily used in the process. This unit ensures that the part rotates in a certain way while processing is in progress.
To move the carriage on the machine, bed guides with a prismatic cross-section are used. This part must maintain certain properties such as accuracy and straightness. Neglecting such conditions will not allow you to get quality work in the end.

Design of sectional horizontal pump CNS 60-165
The main structural units of the pump are the casing and the rotor.
The housing includes suction and discharge line covers, guide vanes, front and rear brackets. The housings of the guide vanes, suction and discharge covers are tightened with coupling bolts.
The guide vane, ring (with sealing rings) and impeller form the pump section. The joints of the guide vane housings are sealed with rubber rings made of oil- and petrol-resistant rubber.
Due to the fact that the pump body consists of separate sections, it is possible, without changing the flow, to change the pressure by installing the required number of impellers and guide vanes with housings. In this case, only the length of the shaft and tie rods changes.
The pump rotor consists of a shaft on which impellers, a ring, a shaft jacket, a spacer sleeve, adjusting rings and a relief disk are installed. All parts on the shaft are tightened with a rotor nut.
The rotor is supported by two radial spherical bearings installed in the front and rear brackets in a sliding fit, allowing the rotor to move in the axial direction by the amount of the rotor “run-up”.
The bearing chambers are sealed with cuffs installed in the bearing caps.
The bracket is closed from the outside with a cover in which a rotor displacement control device is mounted.
Location of components and their list
Instrument limits
Thread pitch limits:
- metric – from 0.01 to 56 mm;
- modular – from 0.01 to 28 modules;
- inch - from 60 to 3.0 threads/inch.
Feed on one limb risk
This parameter depends on how much movement of the caliper is being carried out. In the longitudinal direction, the feed per stroke of the dial corresponds to moving the caliper by a distance of 0.1 mm, and in the transverse direction - 0.02 mm.
The movement of the upper support (cutting slide), corresponding to one division of the dial, corresponds to 0.02 mm. In this case, the division price of the tailstock dial is 0.05 mm.
Electrical diagram
Operating principle of the sectional horizontal pump CNS 60-165
The operation of the pump is based on the interaction of the rotating impeller blades and the pumped liquid.
Rotating, the impeller imparts a circular motion to the fluid located between the blades. Due to the resulting centrifugal force, the liquid from the center of the wheel moves to the external outlet, and the vacated space is again filled with liquid coming from the suction pipe under the influence of the created vacuum.
Having left the impeller of the first section, the liquid enters the channels of the guide vane and then into the second impeller with the pressure created in the first section, from where it enters the third impeller with increased pressure created in the second section, etc.
The liquid released from the last impeller flows through the guide vane into the discharge cover and from it into the discharge pipeline.
During pump operation, due to water pressure on the unequal area lateral surfaces of the impellers, an axial force arises, which tends to displace the pump rotor towards the suction side.
To balance the axial force, the pump is equipped with an unloading device, consisting of an unloading disk, an unloading ring and bushing, and a spacer bushing.
The liquid from the last stage passes through the annular gap between the unloading bushing and the spacer bushing and presses on the unloading disk with a force equal to the sum of the forces acting on the impellers, but directed towards the discharge. The pump rotor is balanced, and equal forces are established automatically.
The liquid leaving the unloading chamber cools the oil seal on the pressure side.
The suction side seal is flushed with liquid supplied under pressure from the suction line. The liquid, passing through the shaft jacket through the stuffing box, prevents air from being sucked into the pump and at the same time cools the stuffing box. Most of the liquid passes through the gap between the shaft jacket and the hydraulic seal sleeve into the suction cavity, some passes between the shaft jacket and the oil seal on the suction side, cooling it, the rest comes out through the fitting.
The tightening of the stuffing box should allow the pumped liquid to leak out between the shaft and the stuffing box packing in an amount of 5-15 l/h. A smaller number indicates that the oil seal is over-tightened, which increases friction losses and accelerates wear of the shaft jacket and rotor nut.
The pump rotor is driven by an electric motor connected to the pump through an elastic sleeve-finger coupling, consisting of two coupling halves (pump and electric motor) and fingers with rubber bushings.
The direction of rotation of the pump rotor is clockwise when viewed from the electric motor.
The pump and electric motor are installed on a common foundation plate so that there is a gap of 10 mm between the coupling halves when the pump rotor is shifted completely towards the suction side.
The unit's electric motor must be grounded before operation.
The CNS pump has self-priming capabilities. This condition is achieved by installing a valve inside the pump.
As part of the central nervous system pumping unit, as a rule, general industrial asynchronous electric motors are installed on the pump. Most often, a three-phase asynchronous motor with a squirrel-cage rotor is used for these purposes.
Pumps are manufactured with both stuffing box and mechanical seals. Leaks through mechanical seals - according to the technical documentation for mechanical seals.
The pump support brackets are made of cast iron, the material of the flow part of the pumps is TsNS SCh-20, Steel 35L, the shaft is steel 40x, the guide vane, ring and body of the guide vane, the oil seal bushing is made of press material AG-4V. The pump shaft is sealed using an stuffing box packing with a cross-section of 10 mm.
CNS pumps operate stably and for a long time with a headwater of 2-6 m. In the absence of headwater at the inlet, cavitation quickly destroys these high-speed pumps. When installing them to pump water with a temperature of more than 45°C, it is necessary to increase the pressure at the inlet to the pump.

Detailed description of the housing and design
The UT16PM lathe has a standard design for the equipment group to which it belongs. It is distinguished by the strength of all its parts.
Aluminum tables are attached to its body, which protects the components and mechanisms located inside it, using which you can easily control this equipment. There is also a nameplate on the case with the logo of the Ulyanovsk Machine-Building Plant engraved on it.
The basis of the design is a cast bed, which ensures the stability of the UT16PM lathe. Machining accuracy is improved by using vibration-absorbing supports. The cooling system has a small electric pump that is turned on as needed. This allows you to increase the interval between starts.
A six-speed gearbox is mounted in the lower part of the structure, having, respectively, six speed levels. It is mounted on the back side of the pedestal of the UT16PM lathe. The gearbox allows you to provide the required rotation speed from 40 to 2000 rpm. The transmission of torque is carried out using V-belts.
The lubrication system guarantees timely supply of oil to parts rubbing against each other. A spindle is installed on the headstock, which is why it is called a spindle. For safety reasons, the possibility of braking, blocking the spindle and protecting it from overloads is provided.
Under the headstock there is a feed box driven by the spindle output shaft. This mechanism allows you to set the thread pitch when cutting. The cabinet with electrical equipment provides electricity supply and switching on the UT16PM lathe. The support is used to secure tools and move them. On its upper part there is a cutter holder.
The closed apron provides longitudinal and transverse feeds of the caliper, as well as thread cutting using a lead screw. The tailstock is used to press the workpiece. Its functioning is especially important when turning long parts.
For an additional fee, you can purchase a rear tool holder, mounted on the transverse slide of the caliper.
