On one hand, an impeller water pump and the air blowpipe are arranged at a water outlet of a screw pump, and pressure at the water outlet of the screw pump is reduce through working of the water pump and the air pump; on the other hand, forward pressure is input into the pressure regulating cavities by the hydraulic oil pump, so that bearings are pushed upwards; and in combination of the two aspects, the counter-acting force borne by the screw shafts is reduced, then the bearing loads are reduced, the bearing abrasion is reduced, and the service life of the submersible pump is prolonged.

An automatic pistol essentially consists of an immovable barrel, a breech with a firing pin and a cartridge extractor, a breech frame, a spring-loaded device for the removal of gas with a gas piston and a gas cylinder, a firing mechanism and a magazine. The barrel is fitted with an end piece, which is located in the lower part of the rear end of the barrel. The design of the breech allows for the displacement of its front part downwards, when the breech is in its front end position. The front part of the breech is fitted with side locking lugs. The corresponding locking grooves are located in the cavities on the end piece of the barrel. The gas piston has an opening for ejecting the cartridge casing. In the course of the backward movement, the gas piston unlocks the breech and draws it back. In the forward movement, the breech is carried forward and pushed downwards. The gas cylinder is located at the front part of the barrel and encompasses the barrel. Along the length of the barrel gas ducts are fixed.

The invention discloses a combined machine tool. The combined machine tool is characterized by comprises a tool body, a rotating and fastening mechanism, a cutting mechanism, a stamping mechanism and a ejecting block; a processing axis is horizontally defined on rotating and fastening mechanism; the cutting mechanism is arranged on the tool body and on one side of the processing axis; the stamping mechanism is arranged on the tool body and on one side of the processing axis; the ejecting block vertically arranged and the stamping mechanism are distributed on two sides of the processing axis facing directly the stamping mechanism and can be arranged on the tool body in a manner of being capable of moving in the direction perpendicular to the processing axis; the cutting mechanism, the stamping mechanism and the ejecting block are located on the front side of the rotating and fastening mechanism. The combined machine tool is good in quality of processed workpieces, good in repeatability, simple in structure and low in cost, and the quality of the processed products can be more easily guaranteed than that of products produced through a tool with only one processing procedure.
