Description
Technical field
The utility model relates to a kind of Centralized and Automatic Lubrication system, particularly relates to a kind of construction machinery and equipment Centralized and Automatic Lubrication system.
Background technology
Lubricating pump in the concrete pumping machinery centralized grease lubricating system extensively adopt electronic lubricating pump (motor-driven), hydrodynamic lubrication pump (hydraulic-driven) or manually lubricating pump (driven by shaking) pumping lubricant medium (grease or lubricating oil) enter in the lubricating pipe of lubricating system, thereby each lubricating point that guarantees concrete pump truck can be regularly, lubricated quantitatively.
The service conditions of concrete pumping machinery very abominable (dust is big, high humidity, to follow pumping to impact shake big), the requirement system can adapt to this rugged environment fully, can realize simultaneously good lubrication automatically to each motor element, system's good anti-vibration, lubricating pump can realize hesitation pumping lubricant medium (saving the lubricant medium consumption).
Use the lubricating system of above-mentioned lubricating pump to have following problem:
1), adopts the Centralized and Automatic Lubrication system of electronic lubricating pump (motor-driven), lubricant medium pressure oil circuit needs by pass valve to adjust pressure, can realize Centralized and Automatic Lubrication, but the import motor costs an arm and a leg, homemade electrical fault is many, the batch (-type) pumping needs the frequent starting motor to cause the motor easy burn-out, the working environment shake is easy to generate electrical accident greatly, has the Installation and Debugging complexity in addition, the shortcoming that fault is more.
2), adopt the Centralized and Automatic Lubrication system of hydrodynamic lubrication pump (hydraulic-driven), can realize Centralized and Automatic Lubrication, the hydrodynamic lubrication pump does not have and independently drives oil circuit, mostly from distributing oil circuit to get hydraulic oil source, lubricating pump follows distribution (or pumping) mechanism to be synchronized with the movement, and lubricant medium pressure oil circuit needs by pass valve to adjust pressure, the more electronic lubricating pump of this mode price is cheap, but times of exercise is many, the installation and maintenance more complicated, and fault is high and be not easy identification; And hydraulic oil and lubricant medium (as grease) are scurried oil (behind the ring wear) and will be caused that hydraulic oil seriously goes bad in the whole hydraulic efficiency pressure system of equipment in the lubricating pump, lose bigger.
3), adopt the centralized grease lubricating system of manual lubricating pump (driven by shaking), can not realize Centralized and Automatic Lubrication, need the artificial frequent lubricating pump that shakes, cause equipment lubrication bad easily.
Adopt the centralized grease lubricating system fault rate height of above lubricating pump, equipment is easy to generate insufficient lubrication, causes the friction between each relative motion component to strengthen because of can not get good lubrication, element shortening in service life, and the equipment that influences normally uses.
The utility model content
Technical problem to be solved in the utility model provides a kind of reliability height, and fault rate is low, and installation and maintenance are simple, can obtain good lubricated construction machinery and equipment Centralized and Automatic Lubrication system by all lubricating points of assurance equipment.
In order to solve the problems of the technologies described above, the construction machinery and equipment that the utility model provides Centralized and Automatic Lubrication system, comprise lubrication box, filter, progressive distributor, the chassis storage tank is connected with the first two-bit triplet change-over valve by pressure regulator, described first two-bit triplet change-over valve outlet is connected with the three-way pipe inlet, an outlet of described three-way pipe is connected with described air-operated lubricating pump by the second two-bit triplet change-over valve, described lubrication box is connected with progressive distributor with described filter by described air-operated lubricating pump, and another outlet of described three-way pipe is connected with pneumatic butter machine.
Described first two-bit triplet change-over valve and the described second two-bit triplet change-over valve are electromagnetism two-bit triplet change-over valve.
Adopt the air-operated lubricating pump Centralized and Automatic Lubrication system of technique scheme, realize the pumping lubricant medium by the perseveration time of two pneumatic butter machines of solenoid control and air-operated lubricating pump.In this system on the one hand the laddering Centralized and Automatic Lubrication system of air-operated lubricating pump group and stepwise type distributor formation provide lubrication protection reliably for the motive position of concrete pump truck distribution system and stirring system; Can be all manual application of lubricant point (alemite) grease ups of concrete pump truck not only on the other hand, realize the mechanization of the manual lubricating point oiling of concrete pump truck technology by pneumatic butter machine (but also claiming high pressure lubricator).The characteristics of this lubricating system are that operation pressure height, consumption of fuel are little, easy to use, labour intensity is low, the various extreme pressure lithium base fat such as 000-2# of annotating.
The chassis compressed air reservoir provides the compressed air-driven propulsion source, and the first two-bit triplet change-over valve is the chassis air pressure switch, and the first two-bit triplet change-over valve was closed when the chassis was in motoring condition, and lubricating system does not have driving power; The first two-bit triplet change-over valve is just connected when only carrying out pumpdown, and lubricating system could normal operation.
In sum, the utility model is a kind of reliability height, fault rate is low, installation and maintenance are simple, can obtain good lubricated construction machinery and equipment Centralized and Automatic Lubrication system by all lubricating points of assurance equipment, can adapt to concrete pumping machinery, overcome all deficiencies of the electronic lubricating pump, hydrodynamic lubrication pump or the manual lubricating pump centralized grease lubricating system that extensively adopt in the industry, have very big promotional value.
